The **token** key is `SHA-256(d)`: `SigningService.createFromSecret(secret)` hashes the secret *before* using it, so the `DIRECT://` token address and all token signatures are a **different elliptic‑curve point** from the chain/messaging key. Code that needs the token key must go through `SigningService.createFromSecret(privKey)` (as `deriveL3PredicateAddress` does).

The two networks + +The Sphere SDK spans two independent networks. The README calls them "tokens" and "the ALPHA coin"; here are their real names and mechanics. (Historically these are referred to as **L3** and **L1**.) + +### 2a. The Unicity token network ("L3") — the core + +This is what the Sphere SDK is fundamentally for. A **token** is a self‑contained cryptographic object: a genesis (mint) record plus a chain of transfers, each anchored by a Merkle **inclusion proof** signed by a Byzantine‑fault‑tolerant validator set (the *trust base*). + +The defining property: **only a commitment (a hash) is ever published on the network.** The token itself — its full history and proofs — lives off‑chain and travels directly between users (over the messaging transport). This buys three things: + +- **Privacy** — the network reveals nothing about amounts, token types, or parties. +- **Scale** — a consensus round absorbs an enormous number of commitments; it is effectively one global sparse Merkle tree of spent states. +- **Offline creation** — commitments can be built without connectivity and submitted later. + +The service that batches commitments into rounds and issues the signed proofs is the **aggregator** (the SDK calls it the *Oracle*). + +### 2b. The ALPHA blockchain ("L1") + +A conventional UTXO chain, Bitcoin‑style (SegWit / P2WPKH, bech32 `alpha1…` addresses). The SDK builds and signs transactions by hand (BIP‑143 signature hashing, low‑S canonical signatures, a fixed fee, 546‑sat dust threshold) and talks to a **Fulcrum** Electrum server over a WebSocket. The connection is *lazy* — it isn't opened until the first ALPHA operation. + +It also includes a **vesting classifier**: it traces each coin back to the coinbase that created it to label it vested or unvested, caching results in IndexedDB (browser) or memory (Node). + +### Network presets + +`createBrowserProviders({ network })` / `createNodeProviders({ network })` wire every service from one name. Endpoint values come from `constants.ts`: + +| Service | mainnet | testnet | dev | +|---|---|---|---| +| Aggregator | `aggregator.unicity.network/rpc` | `goggregator-test.unicity.network` | `dev-aggregator.dyndns.org/rpc` | +| Messaging relay | `relay.unicity.network` | `nostr-relay.testnet.unicity.network` | `nostr-relay.testnet.unicity.network` | +| Fulcrum (ALPHA) | `fulcrum.unicity.network:50004` | `fulcrum.unicity.network:50004` | `fulcrum.unicity.network:50004` | +| Group‑chat relay | `sphere-relay.unicity.network` | `sphere-relay.unicity.network` | `sphere-relay.unicity.network` | + +Token metadata (symbols, decimals, icons) is fetched from a remote registry and cached; prices are optional via a CoinGecko provider. + +--- + +## 3. How a token transfer works + +Sending a token reduces to: commit, prove, deliver. + +``` +1. Resolve recipient (Unicity ID / DIRECT:// / pubkey) → an address object +2. Build a TransferCommitment over the token, recipient, a random 32-byte salt, + an optional on-chain message, signed with the sender's key +3. Submit the commitment to the aggregator +4. Wait for the inclusion proof (proof the commitment landed in a round) +5. Turn commitment + proof into a finalized transfer transaction +6. Deliver { sourceToken, transferTx } to the recipient over the messaging transport +7. Recipient verifies the proof locally against the trust base — the sender is never trusted +``` + +When the amount is smaller than a single token's value, the SDK performs an **atomic split**: it burns the original and mints two new tokens (one for the recipient, one as change), each proof‑verified. Split salts are *deterministic* (derived from the token id and amounts), so a split is replayable and idempotent rather than duplicating value. + +### Two transfer modes + +- **Instant** (default) — all tokens are bundled into one message and shipped immediately; proofs are resolved in the background.

See `docs/uxf/UXF-TRANSFER-PROTOCOL.md` for the canonical spec and `docs/uxf/UXF-TRANSFER-IMPL-PLAN.md` for task breakdown): + - **`payments.importInclusionProof(tokenId, proofBytes, options)`** — operator escape hatch with **10 sub-cases** (1, 2, 3, 4a, 4b, 5, 6, 7, 8, 9 per spec §6.3). `options.allowInvalidOverride: true` flips a `_invalid` token back to `valid` (case 5) or re-queues the K-1 remaining txs (case 6); cases 8/9 short-circuit even with override if the supplied proof doesn't pass verification. Override path stamps `overrideAppliedAt` / `overrideAppliedBy` audit-trail fields on the manifest entry (sticky across CRDT merges) and emits `transfer:override-applied`. + - **`payments.revalidateCascadedChildren(parentTokenId)`** — transitively re-evaluates dispositions for tokens whose `splitParent` chain leads back to a previously-cascaded parent (e.g. after operator override unblocks a parent). Bounded depth (`MAX_CHAIN_DEPTH=64`); per-call-stack visited-set defends against corrupted manifest cycles. + - **13 new `transfer:*` events** on `SphereEventMap`: `transfer:submitted` (instant-mode publish ack, distinct from `transfer:confirmed`), `transfer:cascade-risk-warning` (pending source produces freshly-minted child), `transfer:cascade-failed` (downstream notification on hard-fail), `transfer:trustbase-warning` (first NOT_AUTHENTICATED, refresh-and-retry), `transfer:security-alert` (§6.3 forbidden case OR sustained NOT_AUTHENTICATED post-refresh), `transfer:proof-superseded` (newer proof replaces attached proof per BFT round, W16), `transfer:override-applied` (importInclusionProof override fired), `transfer:operator-alert` (`'client-error'` reason path, C13), `transfer:fetch-failed` (CID gateway-walking exhausted, W13 — NO disposition record written), `transfer:ingest-queue-full` (worker pool back-pressure), `transfer:capability-warning` (peer's wireProtocols / assetKinds mismatch outbound — informational only, no auto-coercion). + - **ConnectHost `IntentSchemaVersion`** — `connect/host/ConnectHost.ts` now passes a 4th argument `schemaVersion: 'uxf-1' | 'legacy'` to the `onIntent` callback (default `'legacy'`; `'uxf-1'` triggered by explicit `params.schemaVersion`, non-empty `additionalAssets[]`, or bundle envelope fields). Backward-compatible — 3-argument integrators keep working. Pure detector exported as `detectIntentSchemaVersion()`. See `docs/uxf/CONNECT-HOST-MIGRATION-NOTE.md` for cross-repo migration (agentsphere, sphere, openclaw-unicity). + - **Multi-asset send** — `TransferRequest.additionalAssets?: AdditionalAsset[]` discriminated union (`{kind:'coin', coinId, amount} | {kind:'nft', tokenId}`) enables multi-coin and mixed coin+NFT transfers in a single `payments.send()` call. Per-kind validation: distinct coinIds incl. primary; distinct NFT tokenIds; coin amounts > 0. Forward-compat: receivers reject unrecognized `kind` with `UNKNOWN_ASSET_KIND`.

See UXF-TRANSFER-PROTOCOL §4.1 and `docs/INTEGRATION.md`. + - **Canonical NFT model** — NFT = token with empty/null `coinData` (after zero-amount pruning); coin = non-empty. Class-disjoint at the protocol level. NFT transfers are whole-token (no split, `tokenId` preserved). Coin tokens cannot satisfy NFT targets even on tokenId match → `INSUFFICIENT_BALANCE` reason='nft-not-owned'. See UXF-TRANSFER-PROTOCOL §4.1. + - **Chain mode opt-in** — `TransferRequest.allowPendingTokens?: boolean` (default `false`). When `true`, the source-token selector may spill over to `pending` tokens after exhausting `valid` ones. Strict ordering: finalized-first, then pending-by-age. See UXF-TRANSFER-PROTOCOL §2.3 + §2.5. + - **`confirmNftPending` flag** — required `true` when `allowPendingTokens: true` AND any NFT target's source has unfinalized predecessor txs. Prevents accidental cascade of irrecoverable NFT identity (`NFT_PENDING_REQUIRES_CONFIRMATION` rejection without it). See UXF-TRANSFER-PROTOCOL §4.1 cascade-asymmetry warning. + - **Identity-binding capability hints** — optional `wireProtocols: string[]` and `assetKinds: string[]` for forward-compat. Informational only — receivers still apply the strict `UNKNOWN_ASSET_KIND` reject rule. See UXF-TRANSFER-PROTOCOL §10.4. + - **Bundle ingest concurrency** — recipient runs a `MAX_INGEST_WORKERS = 16` default worker pool with a bounded ingest queue. DoS defense against rogue long-running bundles. Per-tokenId mutex coordinates cross-bundle conflicts. See UXF-TRANSFER-PROTOCOL §5.0. + - **`_audit` collection** — NEW (Wave T.3). Multi-representation aware: keyed by `${addr}.audit.${tokenId}.${observedTokenContentHash}`. Stores `NOT_OUR_CURRENT_STATE` and `UNSPENDABLE_BY_US` dispositions distinct from cryptographically broken tokens (which stay in `_invalid`, also widened to multi-representation key). See UXF-TRANSFER-PROTOCOL §5.4. + - **Periodic rescans** — two orthogonal scanners promoted to in-scope (design summary): profile-pointer rescan (default 30s, detects sibling-instance updates) and per-token spent-state rescan (default 5 min/token, detects off-record spends). See UXF-TRANSFER-PROTOCOL §12.3. + - **Transfer error model** — canonical against `@unicitylabs/state-transition-sdk`: `REQUEST_ID_MISMATCH` at submit = double-spend signal; sustained `PATH_NOT_INCLUDED` past `POLLING_WINDOW` (default 30 min) = oracle rejected; `PATH_INVALID` / `NOT_AUTHENTICATED` retry up to `MAX_PROOF_ERROR_RETRIES`. Threat model: aggregator faulty-not-hostile; explicit threat boundary in §9.4.1. + - **Most-recent-proof rule** — same `requestId` + same value can have multiple valid proofs across BFT rounds; canonicalize by latest BFT round (supersedes the considered-and-rejected lex-min-CID rule for proofs; lex-min `bundleCid` still governs divergent-chain tie-breaks per UXF-TRANSFER-PROTOCOL §5.3 [D-conflict]). Two proofs for same `requestId` with different values → `transfer:security-alert` (single-spend violation; out-of-scope hostile path). See UXF-TRANSFER-PROTOCOL §6.3. + - **Outbox CRDT invariants** — three-tier state partition (active / soft-terminal / hard-terminal); Lamport clock with `max(local, observed)+1` rule; `overrideApplied` sticky flag for operator-import override stickiness; two-set `commitmentRequestIds` (outstanding + completed) preventing finalized-then-re-added re-submission. See UXF-TRANSFER-PROTOCOL §7.1. + - **Operator escape hatches** — `payments.importInclusionProof(tokenId, proofBytes, {allowInvalidOverride?})` with 10-case enumeration (cases 1, 2, 3, 4a, 4b, 5, 6, 7, 8, 9); `revalidateCascadedChildren(parentTokenId)` (transitive). See UXF-TRANSFER-PROTOCOL §6.3 + §6.1.1. - **`cacheMessages` option for CommunicationsModule** — `communications: { cacheMessages: false }` in `SphereInitOptions` disables DM caching in memory and storage. Messages still flow through `onDirectMessage()` handlers and `message:dm` events, but are never stored. Useful for anonymous/ephemeral agents (e.g. LLM bots) that only need streaming DM reception. `sendDM()` still works but doesn't cache the sent message. Deduplication is skipped when caching is disabled. - **Message signing** — `signMessage()`, `verifySignedMessage()`, `hashSignMessage()` crypto functions for secp256k1 ECDSA with recoverable signatures (Bitcoin-like double-SHA256 with `Sphere Signed Message:\n` prefix). `Sphere.signMessage(message)` instance method encapsulates private key access. `SIGNING_ERROR` added to `SphereErrorCode`. `SphereInstance` interface in ConnectHost extended with `signMessage`. 22 unit tests covering signing, verification, round-trips, tampering detection, and edge cases. - **Centralized logger** — `logger` singleton with `debug`/`warn`/`error` levels, `globalThis`-based state sharing across tsup bundles, per-tag control (`logger.setTagDebug('Nostr', true)`), and custom handler support @@ -33,6 +63,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 - **Sync coalescing** — `PaymentsModule.sync()` now coalesces concurrent calls, preventing race conditions when multiple syncs overlap ### Changed +- **Types — `DEFAULT_IPFS_GATEWAYS` widened to `readonly string[]`** (previously `readonly ['https://unicity-ipfs1.dyndns.org']` literal tuple).

No broadcast, no mempool, no gas auction. +It runs the same way in a browser, in Node.js, and on the command line. -- **Wallet Management** - BIP39/BIP32 key derivation, AES-256 encryption -- **L1 Payments** - ALPHA blockchain transactions via Fulcrum WebSocket -- **L3 Payments** - Token transfers with state transition proofs, concurrent-send safety (SpendQueue) -- **Invoicing / Accounting** - On-chain invoice lifecycle with payment attribution, auto-return, privacy-preserving hashed invoice IDs -- **Token Swaps** - P2P atomic swaps via escrow with DM-based negotiation protocol -- **Payment Requests** - Request payments with async response tracking -- **Group Chat** - NIP-29 relay-based group messaging with moderation -- **Nostr Transport** - Resilient P2P messaging with verified publish, health checks, NIP-17 gift-wrap -- **IPFS Storage** - Decentralized token backup via HTTP API (browser + Node.js) -- **Multi-Address** - HD address derivation (BIP32/BIP44) -- **Token Validation** - Aggregator-based token verification -- **Connect Protocol** - dApp ↔ wallet communication via `ConnectClient` / `ConnectHost` (browser extension + popup) -- **CLI** - Comprehensive command-line interface with shell auto-completion -## Installation +--- + + +## Install ```bash npm install @unicitylabs/sphere-sdk +# Node.js also needs a WebSocket library: +npm install @unicitylabs/sphere-sdk ws ``` -## Quick Start Guides +## Why it's built this way +On Unicity, assets aren't rows in a global database that validators take turns updating. They're self-contained cryptographic objects — bearer instruments — that carry their own history and validity proofs and move directly between two parties. -Choose your platform: +That property is what makes agent-to-agent commerce practical. An autonomous agent can't wait on block space or pay a gas auction for every micro-interaction, and it can't depend on a trusted indexer to know whether it got paid — the proof of the transfer is the payment. Sphere is the client-side toolkit that turns that substrate into the things an agent actually needs: identity, discovery, messaging, trade, and settlement. -| Platform | Guide | Required | Optional | -|----------|-------|----------|----------| -| **Browser** | [QUICKSTART-BROWSER.md](docs/QUICKSTART-BROWSER.md) | SDK only | IPFS sync (built-in) | -| **Node.js** | [QUICKSTART-NODEJS.md](docs/QUICKSTART-NODEJS.md) | SDK + `ws` | IPFS sync (built-in) | -| **CLI** | [@unicity-sphere/cli](https://github.com/unicity-sphere/sphere-cli) | Separate package | - | -| **dApp integration** | [CONNECT.md](docs/CONNECT.md) | SDK only | Sphere extension | +## What you can build with it + +| Capability | Module | What it gives your agent | +| --- | --- | --- | +| **Identity** | `identity` | A cryptographic identity (`@nametag` + secp256k1 keypair) — HD multi-address, one nametag per address | +| **Payments** | `payments` | Send and receive bearer tokens | +| **Payment requests** | `payments` | Request money from a counterparty and track the response asynchronously | +| **Invoicing & settlement** | `accounting` | Issue invoices, take payment, and process returns — the bill-and-collect half of commerce | +| **Discovery** | `market` | Post an intent to transact and search for matching counterparties — how agents *find* each other | +| **Atomic swaps** | `swap` | Trade peer-to-peer with signed swap manifests and nametag bindings — settle a two-sided deal without a trusted middleman | +| **Direct messaging** | `communications` | P2P direct messages and broadcasts over Nostr (NIP-04 encryption) | +| **Group chat** | `groupChat` | NIP-29 relay-based group messaging with roles and moderation | +| **Token backup** | token sync | Decentralized sync to IPFS/IPNS, browser and Node.js | +| **dApp ↔ wallet** | Connect | `ConnectClient` / `ConnectHost` for browser-extension integration | -## CLI (Command Line Interface) -The CLI has moved to a dedicated package: [`@unicity-sphere/cli`](https://github.com/unicity-sphere/sphere-cli). -```bash -npm install -g @unicity-sphere/cli -sphere --help -``` -See [docs/QUICKSTART-CLI.md](docs/QUICKSTART-CLI.md) for the full command reference. -## Quick Start +## Quick start ```typescript import { Sphere } from '@unicitylabs/sphere-sdk'; import { createBrowserProviders } from '@unicitylabs/sphere-sdk/impl/browser'; +// Node.js: import { createNodeProviders } from '@unicitylabs/sphere-sdk/impl/nodejs'; -// Create providers (browser) - defaults to mainnet -const providers = createBrowserProviders(); - -// Or use testnet for development -const testnetProviders = createBrowserProviders({ network: 'testnet' }); - -// Initialize (auto-creates wallet if needed) +// 1.

Requests without a valid nametag will fail. - -## Multi-Address Support -The SDK supports HD (Hierarchical Deterministic) wallets with multiple addresses: - -```typescript -// Get current address index -const currentIndex = sphere.getCurrentAddressIndex(); // 0 - -// Switch to a different address -await sphere.switchToAddress(1); -console.log(sphere.identity?.l1Address); // alpha1... (address at index 1) - -// Register nametag for this address (independent per address) -await sphere.registerNametag('bob'); - -// Switch back to first address -await sphere.switchToAddress(0); - -// Get nametag for specific address -const bobNametag = sphere.getNametagForAddress(1); // 'bob' - -// Get all address nametags -const allNametags = sphere.getAllAddressNametags(); -// Map { 0 => 'alice', 1 => 'bob' } - -// Derive address without switching (for display/receiving) -const addr2 = sphere.deriveAddress(2); -console.log(addr2.address, addr2.publicKey); -``` - -### Identity Properties - -**Important:** L3 (DIRECT address) is the primary address for the Unicity network.

Transfer:', response.transferId); - } -} - -// Or subscribe to responses -sphere.payments.onPaymentRequestResponse((response) => { - console.log(`Response: ${response.responseType}`); -}); +That is a real transfer between two users — verified cryptographically, with no backend of your own required. -// Handle incoming payment requests -sphere.payments.onPaymentRequest((request) => { - console.log(`${request.senderNametag} requests ${request.amount} ${request.symbol}`); +> **Getting test tokens.** On testnet you must claim a Unicity ID first, then request from the faucet.

A user's wallet can hold many tokens of different kinds. +- **Wallet** — created from a 12‑word *recovery phrase*. The phrase is the only thing a user needs to back up; lose it and the wallet is gone. +- **Unicity ID** — a human‑friendly handle (like `@alice`) that people use to pay or message you. Each wallet can claim one. (In the SDK's API this is the `nametag`.) +- **Network** — `testnet` for building and experimenting, `mainnet` for real value. Pick one when you create the wallet; everything else is configured for you. -Relay-based group messaging using the NIP-29 protocol. The module embeds its own Nostr connection separate from the wallet transport. +That's enough to send and receive. Everything below is built on top of these. -### Enabling Group Chat +## Common tasks +**Send tokens** ```typescript -// Enable with network defaults (wss://sphere-relay.unicity.network) -const { sphere } = await Sphere.init({ - ...providers, - autoGenerate: true, - groupChat: true, -}); - -// Enable with custom relay -const { sphere } = await Sphere.init({ - ...providers, - autoGenerate: true, - groupChat: { relays: ['wss://my-nip29-relay.com'] }, -}); - -// Access the module -const gc = sphere.groupChat!; +await sphere.payments.send({ recipient: '@bob', coinId: 'UCT', amount: '1000000' }); ``` -### Connection - +**Check balances and holdings** ```typescript -// Connect to the NIP-29 relay -await gc.connect(); -console.log('Connected:', gc.getConnectionStatus()); - -// Check if current user is a relay admin -const isRelayAdmin = await gc.isCurrentUserRelayAdmin(); +const assets = await sphere.payments.getAssets(); // grouped by token, with prices if enabled +const tokens = sphere.payments.getTokens(); // individual tokens +const balance = sphere.payments.getBalance(); // Asset[] breakdown (synchronous) +const usd = await sphere.payments.getFiatBalance(); // total in USD, or null if prices are off ``` -### Groups - +**Receive tokens** ```typescript -import { GroupVisibility } from '@unicitylabs/sphere-sdk'; - -// Create a public group -const group = await gc.createGroup({ - name: 'General', - description: 'Public discussion', -}); +await sphere.payments.receive(); // pull anything sent to you -// Create a private group -const privateGroup = await gc.createGroup({ - name: 'Team', - visibility: GroupVisibility.PRIVATE, +sphere.on('transfer:incoming', (t) => { + console.log(`Got ${t.tokens.length} token(s) from ${t.senderNametag ?? t.senderPubkey}`); }); - -// Create a write-restricted group (only admins/writers can post) -const announcements = await gc.createGroup({ - name: 'Announcements', - writeRestricted: true, -}); - -// Discover and join -const available = await gc.fetchAvailableGroups(); // public groups on relay -await gc.joinGroup(group.id); - -// Join private group with invite -await gc.joinGroup(privateGroup.id, inviteCode); - -// List joined groups -const groups = gc.getGroups(); - -// Leave or delete -await gc.leaveGroup(group.id); -await gc.deleteGroup(group.id); // admin only ``` -### Messaging - +**Request a payment from someone** ```typescript -// Send a message -const msg = await gc.sendMessage(group.id, 'Hello!'); - -// Reply to a message -await gc.sendMessage(group.id, 'Agreed', { replyToId: msg.id }); - -// Fetch messages from relay -const messages = await gc.fetchMessages(group.id, { limit: 50 }); - -// Get locally cached messages -const cached = gc.getMessages(group.id); - -// Listen for new messages in real-time -const unsubscribe = gc.onMessage((message) => { - console.log(`[${message.groupId}] ${message.senderPubkey}: ${message.content}`); +const req = await sphere.payments.sendPaymentRequest('@bob', { + amount: '1000000', coinId: 'UCT', message: 'Invoice #1234', }); +const res = await sphere.payments.waitForPaymentResponse(req.requestId!, 120000); ``` -### Members & Moderation - -```typescript -// Get members -const members = gc.getMembers(group.id); - -// Check roles -gc.isCurrentUserAdmin(group.id); // boolean -gc.isCurrentUserModerator(group.id); // boolean -await gc.canModerateGroup(group.id); // includes relay admin check -gc.canWriteToGroup(group.id); // false if write-restricted and not admin/moderator - -// Moderate (requires admin/moderator role) -await gc.kickUser(group.id, userPubkey, 'reason'); -await gc.deleteMessage(group.id, messageId); -``` - -### Invites (Private Groups) - -```typescript -// Create invite code (admin only) -const invite = await gc.createInvite(group.id); - -// Share invite code, recipient joins with: -await gc.joinGroup(group.id, invite); -``` - -### Unread Counts - -```typescript -const total = gc.getTotalUnreadCount(); -gc.markGroupAsRead(group.id); -``` - -### Key Types - -```typescript -interface GroupData { - id: string; - relayUrl: string; - name: string; - description?: string; - visibility: GroupVisibility; // 'PUBLIC' | 'PRIVATE' - writeRestricted?: boolean; // Only admins and moderators can post - memberCount?: number; - unreadCount?: number; - lastMessageTime?: number; - lastMessageText?: string; -} - -interface GroupMessageData { - id?: string; - groupId: string; - content: string; - timestamp: number; - senderPubkey: string; - senderNametag?: string; - replyToId?: string; -} - -interface GroupMemberData { - pubkey: string; - groupId: string; - role: GroupRole; // 'ADMIN' | 'MODERATOR' | 'MEMBER' - nametag?: string; - joinedAt: number; -} -``` - -## Direct Messages (NIP-17) - -End-to-end encrypted DMs via NIP-17 gift wrap, accessed through `sphere.communications`: - +**Send a direct message** ```typescript -// Send a DM (by nametag or pubkey) await sphere.communications.sendDM('@alice', 'Hello!'); - -// Listen for incoming DMs -sphere.communications.onDirectMessage((msg) => { - console.log(`From ${msg.senderNametag ?? msg.senderPubkey}: ${msg.content}`); -}); -``` - -### DM History on Connect - -By default, the SDK resumes from the last processed DM timestamp (persisted in storage). On first connect, it starts from "now" — no historical replay. - -Use `dmSince` to control how far back to fetch DMs on first connect: - -```typescript -const { sphere } = await Sphere.init({ - ...providers, - autoGenerate: true, - dmSince: Math.floor(Date.now() / 1000) - 86400, // last 24 hours -}); -``` - -Once the SDK processes DMs, the timestamp is persisted and `dmSince` is ignored on subsequent connects. - -### Ephemeral Mode (No Caching) - -For anonymous agents or LLM bots that don't need message history, disable DM caching: - -```typescript -const { sphere } = await Sphere.init({ - ...providers, - communications: { cacheMessages: false }, -}); - -// Stream-only: receive, process, forget -sphere.communications.onDirectMessage((msg) => { - processAndReply(msg); -}); - -// sendDM still works — message is sent but not stored locally -await sphere.communications.sendDM('@alice', 'response'); -``` - -When `cacheMessages` is `false`: -- `onDirectMessage()` handlers and `message:dm` events fire normally -- Messages are never stored in memory or persisted to storage -- `getConversation()` / `getConversations()` return empty results -- Deduplication is skipped (duplicate relay deliveries may trigger duplicate events) - -## L1 (ALPHA Blockchain) Operations - -Access L1 payments through `sphere.payments.l1`: - -```typescript -// L1 is enabled by default with lazy Fulcrum connection. -// Connection to Fulcrum is deferred until first L1 operation. -const { sphere } = await Sphere.init({ - ...providers, - autoGenerate: true, - // L1 config is optional — defaults are applied automatically: - // electrumUrl: network-specific (mainnet: fulcrum.alpha.unicity.network) - // defaultFeeRate: 10 sat/byte - // enableVesting: true -});

-``` - -## Custom Token Storage Provider - -You can implement your own `TokenStorageProvider` for custom storage backends: - -```typescript -import type { TokenStorageProvider, TxfStorageDataBase, SaveResult, LoadResult, SyncResult } from '@unicitylabs/sphere-sdk/storage'; -import type { FullIdentity, ProviderStatus } from '@unicitylabs/sphere-sdk/types'; - -class MyCustomStorageProvider implements TokenStorageProvider { - readonly id = 'my-storage'; - readonly name = 'My Custom Storage';

Valid formats: lowercase alphanumeric with `_` or `-` (3–20 chars), or E.164 phone numbers (e.g., `+14155552671`). Input is normalized to lowercase automatically. - -> **Important:** Nametags are required to use the testnet faucet. Register a nametag before requesting test tokens. - -> **Note:** Nametag minting requires an aggregator API key for proof verification. Configure it via the `oracle.apiKey` option when creating providers. Contact Unicity to obtain an API key. - -### Registering a Nametag - -```typescript -// During wallet creation -const { sphere } = await Sphere.init({ - ...providers, - mnemonic: 'your twelve words...', - nametag: 'alice', // Will register @alice -}); - -// Or after creation -await sphere.registerNametag('alice'); - -// Mint on-chain nametag token (required for receiving via PROXY addresses) -const result = await sphere.mintNametag('alice'); -if (result.success) { - console.log('Nametag minted:', result.nametagData?.name); -} -``` - -### Common Pitfall: Nametag Already Taken - -If you see this error: -``` -Failed to register nametag. It may already be taken. -[NostrTransportProvider] Nametag already taken: myname - owner: f124f93ae6946ffd... -``` - -This means the nametag is registered to a **different public key**. Common causes: - -1. **Storage cleared or not persisting**: - - `Sphere.exists()` returns `false` because storage is empty/inaccessible - - SDK creates a new wallet with new keypair - - Nametag registration fails because old pubkey owns it on Nostr - -2. **Different mnemonic provided**: - ```typescript - // ❌ WRONG: Random mnemonic each time - const mnemonic = Sphere.generateMnemonic(); - const { sphere } = await Sphere.init({ - mnemonic, - nametag: 'myservice', // Fails after first run - }); - ``` - -**Note:** `autoGenerate: true` does NOT generate a new mnemonic on every restart. It only generates one if `Sphere.exists()` returns `false` (wallet not found in storage). - -### Solution: Persistent Storage or Fixed Mnemonic - -**Option 1: Persistent file storage** (recommended for backend): - -```typescript -import { FileStorageProvider } from '@unicitylabs/sphere-sdk/impl/nodejs'; - -const storage = new FileStorageProvider('./wallet-data'); // Persists to disk - -const { sphere } = await Sphere.init({ - storage, - autoGenerate: true, // OK: mnemonic saved to disk, reused on restart - nametag: 'myservice', -}); -``` - -**Option 2: Fixed mnemonic from environment**: - -```typescript -const { sphere } = await Sphere.init({ - ...providers, - mnemonic: process.env.WALLET_MNEMONIC, // Same mnemonic every time - nametag: 'myservice', -}); -``` - -### Debugging Storage Issues - -If nametag fails unexpectedly, check if wallet exists: - -```typescript -const exists = await Sphere.exists(storage); -console.log('Wallet exists:', exists); // Should be true after first run - -// If false - storage is not persisting properly -``` - -### Nametag Recovery on Import - -When importing a wallet (from mnemonic or file), the SDK automatically attempts to recover the nametag from Nostr: - -```typescript -// Import wallet - nametag will be recovered automatically if found on Nostr -const { sphere } = await Sphere.init({ - ...providers, - mnemonic: 'your twelve words...', - // No nametag specified - will try to recover from Nostr -}); - -// Listen for recovery event -sphere.on('nametag:recovered', (event) => { - console.log('Recovered nametag:', event.data.nametag); // e.g., 'alice' -}); - -// After init, check if nametag was recovered -console.log(sphere.identity?.nametag); // 'alice' (if found on Nostr) -``` - -### Multi-Address Nametags - -Each derived address can have its own independent nametag: - -```typescript -// Address 0: @alice -await sphere.registerNametag('alice'); - -// Switch to address 1 and register different nametag -await sphere.switchToAddress(1); -await sphere.registerNametag('bob'); - -// Now: -// - Address 0 → @alice -// - Address 1 → @bob - -// Get nametag for specific address -const aliceTag = sphere.getNametagForAddress(0); // 'alice' -const bobTag = sphere.getNametagForAddress(1); // 'bob' -``` - ---- - -See [IPFS Storage Guide](docs/IPFS-STORAGE.md) for complete IPFS/IPNS documentation including configuration, caching, merge rules, and troubleshooting. - ---- +There is also a command‑line tool in a separate package, [`@unicity-sphere/cli`](https://github.com/unicity-sphere/sphere-cli). -## Known Limitations / TODO +## Glossary -### Wallet Encryption +- **Recovery phrase (mnemonic)** — 12 words that *are* the wallet. Back them up; never share them. +- **Token** — a unit of digital value held in a wallet (e.g. `UCT`). +- **Unicity ID** — a human‑readable handle for a wallet (e.g. `@alice`). Lowercase letters/digits with `-` or `_`, 3–20 characters. Called `nametag` in the SDK's API. +- **Wallet address** — the machine‑readable address behind a Unicity ID. People rarely type it; they use the handle (e.g. `@alice`). +- **ALPHA coin** — the coin of Unicity's base blockchain. Sent through `sphere.payments.l1`. +- **Smallest unit** — token amounts are integers in the token's smallest denomination, passed as strings (so `"1000000"`, not `1.0`). +- **Provider** — a pluggable backend (storage, messaging, etc.). `createBrowserProviders()` / `createNodeProviders()` set these up for you. +- **Network** — `testnet` (free, for building) or `mainnet` (real value). -Currently, wallet mnemonics are encrypted using a default key (`DEFAULT_ENCRYPTION_KEY` in constants.ts). This provides basic protection but is not secure for production use. +## Platforms -**Future implementation needed:** -- Add user password parameter to `Sphere.create()`, `Sphere.load()`, and `Sphere.init()` -- Derive encryption key from user password using PBKDF2/Argon2 -- Migration strategy for existing wallets: - 1. Try decrypting with user-provided password first - 2. If decryption fails, fallback to `DEFAULT_ENCRYPTION_KEY` - 3. If fallback succeeds, re-encrypt with new user password - 4.

NFT and coin tokens are class-disjoint — no single token carries both. NFT transfers preserve the source `tokenId`; coin transfers split via mint, producing fresh `tokenId`s for recipient and change. + +**Pending NFT cascade caveat**: when `allowPendingTokens: true` is set AND any NFT target's source has unfinalized predecessor txs in its history, you MUST pass `confirmNftPending: true` to acknowledge the cascade-asymmetry risk (otherwise the call rejects with `NFT_PENDING_REQUIRES_CONFIRMATION`). Finalized (valid) NFT sources do NOT require the confirmation even with `allowPendingTokens: true` — the requirement is gated on the NFT source actually being pending.

It does NOT scrub the snapshot's +`privateKey` post-callback — see the security-review note below for why. + +## Security review (steelman attack vectors considered) + +1. **Does the helper actually keep privateKey from leaking outside the SDK?** + - The `FullIdentity` snapshot is constructed inside Sphere and passed + ONLY into the callback. The callback shape is `(id) => void`; the + attach-identity wrapper invokes only `setIdentity` on the providers + (a sync method that derives the encryption key inline and stores + the identity reference internally). Consumer code receives only + the constructed providers — never the identity, never the + `FullIdentity` reference. + - **Steelman round 1 catch**: an earlier draft included a `finally` + block that scrubbed `snapshot.privateKey = undefined` post-callback + to reduce GC retention of the secret. This was REMOVED because the + `ProfileStorageProvider` stores the snapshot reference and reads + `identity.privateKey` LAZILY inside `connect()` Phase B (see + `profile-storage-provider.ts` `identityAtStart.privateKey` at line + 709). A post-callback scrub would null out the authoritative copy + mid-attach, breaking OrbitDB connection setup. The Sphere + `_identity.privateKey` field IS the long-lived secret regardless; + the provider's stored reference adds no new exposure (it lives + for the same Sphere lifetime). + +2. **Uninitialized Sphere — clear error path?** + - `_withFullIdentityForProfileFactory` throws + `SphereError('NOT_INITIALIZED')` when `_identity?.privateKey` is + falsy. Distinct from the cryptic `hexToBytes: empty hex string` + RangeError the consumer-facing pre-#292 bug threw. + +3. **Malicious / buggy consumer corrupting encryption-key state?** + - The new factories internally call `setIdentity` once before returning + control to the consumer. A subsequent + `profile.tokenStorage.setIdentity({...identity, privateKey: ''})` call + by the consumer would still throw inside `hexToBytes` — the existing + contract is preserved. The new factories don't WEAKEN that contract; + they provide a key-safe SUCCESSFUL path. + +4. **Concurrent factory calls — shared state safety?** + - Each factory call constructs its own Profile providers (no shared + state). The Sphere accessor uses a local-const snapshot per call, so + concurrent calls each get their own snapshot and don't interfere. + +5. **Memory: does the helper retain a Sphere reference?** + - No. The helper takes a `Sphere` parameter but does not store it. The + producers (the Profile factories) discard the Sphere reference once + `attachIdentityToProfileProviders` returns. The constructed providers + hold only their own internal state (encryption key derived from the + identity) — they do not hold a back-reference to Sphere. + +6. **Pre-existing leakage point — `ProfileTokenStorageProvider.getIdentity()`** + - **Caveat — this is OUT OF SCOPE for this PR but worth flagging.** + The `ProfileTokenStorageProvider` class exposes a public + `getIdentity(): FullIdentity | null` method that returns the stored + identity, INCLUDING `privateKey`. A consumer of the providers built + by `createBrowserProfileProvidersFromSphere` can therefore extract + the wallet's private key after calling the factory. + - This leakage existed BEFORE #292 — consumers who manually called + `tokenStorage.setIdentity(fullIdentity)` could read back the same + identity via `getIdentity()`. The Sphere-bound factories do not + introduce a NEW exposure; they remove the consumer-facing path that + required synthesizing a `FullIdentity`. + - Closing this gap requires migrating + `ProfileTokenStorageProvider.getIdentity()` to return `Identity` (no + privateKey) and routing the existing internal callers (the lifecycle + manager's `Phase B` connect, `factory.ts` line 458) through a separate + internal-only accessor — too large to bundle here. + - **Tracked as part of the follow-up SphereCryptographer migration + ([#293](https://github.com/unicity-sphere/sphere-sdk/issues/293))**.

NFT reservations are existence-based, not amount-based — a coin token cannot satisfy an NFT target even on tokenId match (per the canonical asset model: NFT = empty `coinData`, class-disjoint from coin).

Storage Abstraction + +### 7.1 Design Decision: UXF Wraps, Does Not Replace, TXF Storage + +UXF is a **packaging layer** on top of the existing token storage. It does not replace `TokenStorageProvider` or `TxfStorageData`. Instead: + +- `UxfPackage` can be populated from `TxfStorageData` by iterating its tokens and calling `ingest()` for each. +- `UxfPackage` can export back to `TxfStorageData` by calling `assemble()` for each token in the manifest. +- For direct UXF persistence, a new `UxfStorageAdapter` interface is provided. + +This keeps UXF decoupled from wallet lifecycle and allows incremental adoption. + +### 7.2 UXF Storage Adapter Interface + +```typescript +// uxf/types.ts + +/** + * Abstract storage adapter for persisting UXF packages. + * Platform implementations live in impl/browser/ and impl/nodejs/. + */ +export interface UxfStorageAdapter { + /** + * Save the full package state. + * The implementation may serialize as JSON, CBOR, or any internal format. + */ + save(pkg: UxfPackageData): Promise; + + /** + * Load a previously saved package, or null if none exists. + */ + load(): Promise; + + /** + * Delete the stored package. + */ + clear(): Promise; +} +``` + +### 7.3 Platform Implementations + +**In-memory (testing/ephemeral):** +```typescript +export class InMemoryUxfStorage implements UxfStorageAdapter { + private data: UxfPackageData | null = null; + async save(pkg: UxfPackageData) { this.data = pkg; } + async load() { return this.data; } + async clear() { this.data = null; } +} +``` + +**Browser (IndexedDB):** +A new IndexedDB database `sphere-uxf-storage` with a single object store `package`. Elements are stored as individual records keyed by content hash for efficient incremental updates. The manifest and envelope are stored under reserved keys. + +**Node.js (File-based):** +A directory containing: +- `envelope.json` -- package envelope +- `manifest.json` -- token manifest +- `elements/` -- one file per element, named `{hash}.cbor` +- `instance-chains.json` -- instance chain index + +### 7.4 Integration with Existing StorageProvider + +The `UxfStorageAdapter` can optionally delegate to the existing `StorageProvider` KV interface by serializing the package to JSON and storing it under a well-known key. This avoids creating new platform-specific storage implementations for simple use cases: + +```typescript +/** + * Adapter that stores UXF package data via the existing StorageProvider KV interface. + */ +export class KvUxfStorageAdapter implements UxfStorageAdapter { + constructor( + private readonly storage: StorageProvider, + private readonly key: string = 'uxf_package', + ) {} + + async save(pkg: UxfPackageData): Promise { + await this.storage.set(this.key, packageToJson(pkg)); + } + + async load(): Promise { + const json = await this.storage.get(this.key); + return json ? packageFromJson(json) : null; + } + + async clear(): Promise { + await this.storage.remove(this.key); + } +} +``` + +--- + +## 8.

+``` + +--- + +## Summary of Key Architectural Decisions + +1. **Separate top-level directory** (`uxf/`) rather than under `modules/` -- UXF is a data format/packaging concern, not a wallet-lifecycle module. It has zero runtime dependencies on `Sphere`, `PaymentsModule`, or transport. + +2. **Platform-neutral** -- the core UXF module has no platform-specific code. Storage adapters are injected. CBOR encoding uses `@ipld/dag-cbor` for deterministic serialization. + +3. **Content hash = SHA-256 over deterministic CBOR** -- this aligns with IPLD's dag-cbor codec and produces CIDv1-compatible addresses. The same hash serves as both the pool key and the IPLD CID digest. + +4. **Elements reference children by hash, never inline** -- this is the fundamental property that enables structural sharing. A unicity certificate buried inside token A's inclusion proof is the same pool entry referenced by token B's inclusion proof. + +5. **Instance chains as singly-linked lists** -- new instances prepend to the chain and reference the previous head as predecessor. The instance chain index provides O(1) lookup from any hash to the chain head. All instances are retained (append-only pool). + +6. **Explicit garbage collection** -- removing a token from the manifest does not automatically delete its elements (they may be shared). The consumer calls `gc()` when ready. This avoids reference counting overhead and surprise data loss. + +7. **Wraps TXF, does not replace it** -- UXF ingests `ITokenJson` objects (from `@unicitylabs/state-transition-sdk`) and reassembles them back. A thin adapter converts sphere-sdk's `TxfToken` to `ITokenJson` for integration. The existing `TxfStorageData` format remains the wallet's primary persistence format. UXF is an opt-in layer for deduplication, IPFS export, and multi-token packaging. + +8. **Minimal new dependencies** -- CBOR encoding uses `@ipld/dag-cbor` + `multiformats` (~50-80 KB minified). SHA-256 comes from `@noble/hashes` (already bundled). CAR file import/export uses `@ipld/car`. UXF is a separate tsup entry point, so consumers who don't use UXF don't pay the dependency cost. + +--- + +## 9. Profile Module Integration + +The Profile module (`@unicitylabs/sphere-sdk/profile`) extends UXF with +OrbitDB-backed wallet storage. It uses UxfPackage for token packaging +and adds: + +- **ProfileStorageProvider** -- implements StorageProvider with OrbitDB + local cache +- **ProfileTokenStorageProvider** -- implements TokenStorageProvider using multi-bundle UXF +- **OrbitDB adapter** -- dynamic-import wrapper for @orbitdb/core +- **Encryption** -- AES-256-GCM with HKDF-derived shared key +- **Migration engine** -- 6-step legacy-to-Profile conversion + +The Profile module is a separate entry point (`./profile`) with its own +dependencies (@orbitdb/core, helia as optional peerDependencies). It does +not modify any existing SDK files -- factories are standalone. + +See docs/uxf/PROFILE-ARCHITECTURE.md for the full specification. \ No newline at end of file diff --git a/docs/uxf/CONNECT-HOST-MIGRATION-NOTE.md b/docs/uxf/CONNECT-HOST-MIGRATION-NOTE.md new file mode 100644 index 00000000..89ccf6e0 --- /dev/null +++ b/docs/uxf/CONNECT-HOST-MIGRATION-NOTE.md @@ -0,0 +1,156 @@ +# ConnectHost — UXF-1 Intent `schemaVersion` Migration Note + +> Task: **T.7.C.5** — ConnectHost coordination + external repo type-widening (C5). +> Status: shipped on `feature/uxf-packaging-format`. +> Audience: integrators of `ConnectHost` (sphere app, agentsphere, third-party +> wallet hosts). + +## TL;DR + +`ConnectHost` now passes a fourth argument to the `onIntent` callback (and +to `setIntentAutoApprove` handlers): a string literal **`schemaVersion`** +that tells the wallet UI whether the incoming intent payload uses the new +**UXF-1** packaging format or the **pre-UXF (legacy)** shape. + +```ts +type IntentSchemaVersion = 'uxf-1' | 'legacy'; + +onIntent( + action: string, + params: Record, + session: ConnectSession, + schemaVersion?: IntentSchemaVersion, // <-- NEW (4th arg) +): Promise<{ result?: unknown; error?: { code: number; message: string } }>; +``` + +The argument is **optional at the type level**, which means existing +three-parameter callbacks compile and run unchanged. The default value +emitted by the host when nothing UXF-1-specific is detected is +**`'legacy'`** — full backward compatibility. + +## Why + +UXF-1 widens intents to multi-asset payloads (`additionalAssets[]`, +mixed coin + NFT bundles, top-level `bundle` envelopes). Wallet UIs +that render the confirmation modal have to know *which schema* they are +looking at so they can: + +- pick the right confirmation layout (single-asset vs. multi-asset + summary panel), +- run schema-appropriate validation before signing, +- tag the resulting on-chain artefacts with the format used. + +Previously, integrators had to sniff `params` themselves and risked +drifting from the SDK’s canonical detection rules. The host now does +this once, centrally, and forwards the result. + +## Detection rules (canonical) + +The host returns `'uxf-1'` if **any** of the following hold for `params`: + +1. `params.schemaVersion === 'uxf-1'` (explicit declaration by the dApp). +2. `params.additionalAssets` is a non-empty array + (multi-asset extension — coin or NFT entries). +3. `params.bundle`, `params.uxfBundle`, or `params.uxf` is present and + non-null (a UXF envelope is being shipped end-to-end). + +Otherwise — including when `params` is `undefined`, `null`, or any other +non-object — the host returns `'legacy'`. Detection is **pure**, never +throws, and never mutates the dApp-supplied `params` object. + +The detector is also exported as a standalone function for hosts that +want to apply the same rule outside the callback path: + +```ts +import { detectIntentSchemaVersion } from '@unicitylabs/sphere-sdk/connect'; +``` + +## How to migrate + +### 1. Widen the callback type + +If your existing code declares `onIntent` as a strictly three-parameter +function, widen the signature: + +```ts +// before +const onIntent = async ( + action: string, + params: Record, + session: ConnectSession, +) => { /* … */ }; + +// after +import type { IntentSchemaVersion } from '@unicitylabs/sphere-sdk/connect'; + +const onIntent = async ( + action: string, + params: Record, + session: ConnectSession, + schemaVersion: IntentSchemaVersion = 'legacy', +) => { /* … */ }; +``` + +The default `= 'legacy'` keeps your code tolerant to older SDK versions +that do not yet emit the argument. + +### 2. Branch on the schema version + +```ts +if (schemaVersion === 'uxf-1') { + return openUxfConfirmModal(action, params, session); +} +return openLegacyConfirmModal(action, params, session); +``` + +If you do not need to branch yet, you can simply ignore the new argument +— the legacy code path remains correct because every legacy payload is +still tagged `'legacy'`. + +### 3. Apply the same change to auto-approve handlers + +`ConnectHost.setIntentAutoApprove(action, handler)` forwards the same +`schemaVersion` argument to the registered handler. Widen its signature +the same way if you want to gate auto-approval on schema version: + +```ts +host.setIntentAutoApprove('send', async (action, params, session, schemaVersion) => { + if (schemaVersion === 'uxf-1') { + // …new auto-approve policy for multi-asset bundles + } + // …existing legacy policy +}); +``` + +## Compatibility matrix + +| Caller declares `onIntent` with… | Result on this SDK version | +| --- | --- | +| 3 parameters (legacy) | Works.

These are structurally different — critically, `TxfToken.nametags` is `string[]` while `ITokenJson.nametags` is recursive `Token[]`. The token analysis confirmed nametag deduplication is the #2 savings target (~350 KB per 100-token wallet). + +**Decision:** UXF operates on `ITokenJson` from `@unicitylabs/state-transition-sdk` as its canonical input/output format. The sphere-sdk `TxfToken` type is a convenience wrapper — UXF ingests and emits `ITokenJson` (or its CBOR equivalent). + +**Implication:** The `ingest()` and `assemble()` APIs accept/return `ITokenJson`. A thin adapter converts `TxfToken` → `ITokenJson` for sphere-sdk integration. Nametag tokens are recursively deconstructed as full token sub-DAGs, not stored as string names. + +--- + +## Decision 2: UXF Scope — Exchange Format First, Storage Adapter Second + +**Context:** The reviewer (Finding 3.2) noted that `TxfStorageData` contains wallet-operational metadata (`_outbox`, `_tombstones`, `_mintOutbox`, `_sent`, `_nametags`) that TASK.md does not address. UXF cannot replace TXF as a storage backend without handling these. + +**Decision:** UXF is primarily a **token packaging/exchange format**, not a wallet state format. Implementation proceeds in two phases: + +- **Phase 1 (MVP):** UXF as a standalone library that ingests/emits `ITokenJson` tokens. No wallet metadata. `PaymentsModule` continues using `TxfStorageData` for persistence. UXF is used for IPFS export, cross-device sync, and multi-token exchange bundles. +- **Phase 2 (future):** `UxfStorageAdapter` implementing `TokenStorageProvider` that internally uses UXF for persistence, with wallet metadata stored in the package envelope. Migration logic converts existing `TxfStorageData` on first load. + +**Implication:** The package envelope metadata section (Section 5.3 of the spec) is kept minimal for Phase 1. Wallet-specific fields (`_outbox`, `_tombstones`) are excluded. The `UxfPackage` class does not depend on `PaymentsModule`, `Sphere`, or any wallet lifecycle class. + +--- + +## Decision 3: Use @ipld/dag-cbor, Not Hand-Written CBOR + +**Context:** The architect proposed hand-writing a minimal CBOR encoder (~200 lines) to avoid new dependencies. The IPFS researcher showed that `@ipld/dag-cbor` provides critical determinism guarantees (RFC 8949 canonical encoding, sorted map keys, Tag 42 for CID links) that would be error-prone to reimplement and are essential for content-addressability. + +**Decision:** Use `@ipld/dag-cbor` (v9.2.5) + `multiformats` (v13.4.2) as dependencies. These are well-maintained, ESM-native, and provide the exact deterministic serialization + CID computation needed. + +**Rationale:** +- dag-cbor canonical encoding is non-trivial to implement correctly (key sorting by CBOR byte order, not string order; BigInt handling; float canonicalization). Getting it wrong breaks content-addressability silently. +- `@ipld/dag-cbor` + `multiformats` together add ~50-80 KB minified. This is acceptable given that the SDK already bundles `@noble/hashes` (~25 KB) and `@noble/curves` (~80 KB). +- Native CID link support (Tag 42) means UXF elements are directly usable as IPLD blocks without transformation. + +**Mitigation for bundle size:** UXF is a separate tsup entry point (`@unicitylabs/sphere-sdk/uxf`). Consumers who don't use UXF don't pay the dependency cost. The main SDK barrel re-exports types only, not runtime code. + +**Additional dependency:** `@ipld/car` (v5.4.2) for CAR file import/export. This is optional — only imported when CAR operations are used. + +--- + +## Decision 4: A UXF Bundle IS a CAR File + +**Context:** The IPFS researcher demonstrated that CAR (Content Addressable aRchive) maps 1:1 to the UXF bundle concept: element pool → IPLD blocks, manifest root → CAR root CID, content hashes → CIDs. + +**Decision:** The native binary serialization of a UXF package is a **CARv1 file**. The JSON format remains available for debugging and human inspection. + +**Structure:** +- CAR root: CID of the manifest+metadata block (dag-cbor encoded) +- Blocks: one IPLD block per element, each dag-cbor encoded with CID links (Tag 42) for child references +- Block ordering: manifest first, then BFS traversal from each token root (enables streaming) + +**Implication:** `UxfPackage.toCar()` and `UxfPackage.fromCar()` are the primary serialization methods. CAR files can be uploaded directly to IPFS pinning services (Storacha, Pinata) or exchanged peer-to-peer. The existing sphere-sdk IPFS integration can be extended to upload CAR files instead of JSON blobs. + +--- + +## Decision 5: Decomposition Granularity — Mid-Level, Data-Driven + +**Context:** The token analysis provided concrete byte sizes and sharing ratios. The reviewer (Finding 1.5) warned about overhead for small elements. The IPFS researcher recommended mid-level granularity. + +**Decision:** Decompose at the level where measured deduplication benefit exceeds CID overhead (~36 bytes per reference). Based on token analysis data: + +| Element | Separate DAG node? | Rationale | +|---------|-------------------|-----------| +| **UnicityCertificate** | Yes | 1-4 KB, shared by 5-10 tokens/round. Primary dedup target. | +| **Nametag Token** | Yes (full recursive sub-DAG) | 5-8 KB, shared by 10-100 tokens. Second dedup target. | +| **InclusionProof** | Yes | Container for auth + path + cert references. Enables cert sharing. | +| **Authenticator** | Yes | ~300 bytes. Separating it enables proof restructuring without touching auth data. | +| **SmtPath** | Yes (single node, not per-segment) | 1.5-5.5 KB. Per-segment sharing is minimal (<15%). Keep as one node. | +| **GenesisTransaction** | Yes | Container for data + proof + state references. | +| **TransferTransaction** | Yes | Container for state + data + proof references. | +| **MintTransactionData** | Yes | ~500 bytes. Unique per token but structurally needed for the DAG. | +| **TransferTransactionData** | Yes | ~200 bytes. Structurally needed. | +| **TokenState** | Yes | ~500 bytes. Referenced by transactions as source/destination. | +| **Predicate** | Yes | ~400 bytes. Referenced by TokenState. Low sharing but cleanly separable. | +| **TokenCoinData** | Yes | ~150 bytes. Same-value tokens share it. | +| **SmtPathSegment** | **No — inline in SmtPath** | ~140 bytes each. Per-segment sharing is minimal. CID overhead exceeds savings. | + +**Key change from spec draft:** SmtPathSegments are NOT separate elements. The SmtPath element contains the full steps array inline. This eliminates 10-40 tiny elements per proof with negligible dedup loss. + +**Estimated element count per token (5 transactions):** ~35 elements (down from ~140 with per-segment decomposition). For 100 tokens: ~3,500 elements, ~1,750 after dedup. + +--- + +## Decision 6: Instance Chain Branching — Last-Writer-Wins with Merge Detection + +**Context:** The reviewer (Finding 1.2) identified that concurrent independent updates to the same element create forks in the instance chain. + +**Decision:** Instance chains remain singly-linked (not DAGs). On `merge()`: +1. If both packages have an instance chain for the same element, and one chain is a prefix of the other, the longer chain wins. +2. If the chains diverge (different heads, neither is a prefix), both heads are kept as **sibling instances** — the instance chain index records multiple heads for that element, and the selection strategy can choose between them. +3. The `verify()` operation reports divergent chains as warnings (not errors). + +**Rationale:** True forks are rare in practice (they require two independent agents updating the same proof concurrently). The simple last-writer-wins model handles the common case; sibling tracking handles the edge case without breaking the chain model. + +--- + +## Decision 7: Mandatory Integrity Checks on Reassembly + +**Context:** The reviewer (Finding 5.1) noted that the spec never mandates re-hashing elements during reassembly to detect corruption. + +**Decision:** `assemble()` re-hashes every element fetched from the pool and compares against the expected content hash. If any mismatch is detected, reassembly fails with a `VERIFICATION_FAILED` error. This is cheap (SHA-256 is fast) and essential for security. + +**Additional:** `merge()` verifies all incoming elements' content hashes before adding them to the pool, preventing instance chain poisoning (Finding 5.2). + +--- + +## Decision 8: DAG Acyclicity Enforcement + +**Context:** The reviewer (Finding 1.4) noted that circular references could cause infinite recursion during reassembly. + +**Decision:** Reassembly tracks visited element hashes in a `Set`. If an element is visited twice during the same reassembly operation, it throws a `CYCLE_DETECTED` error. `verify()` also performs a full cycle check on the element pool. + +--- + +## Decision 9: Defer ZK Proofs and Proof Consolidation to Phase 2 + +**Context:** The reviewer (Findings 3.5, 3.6) noted that ZK proof substitution requires a ZK system (none exists in the codebase) and proof consolidation requires aggregator cooperation (undefined semantics). + +**Decision:** Phase 1 implements the instance chain mechanism and tests it with mock alternative instances. The `addInstance()` API works for any element type. `consolidateProofs()` is **not implemented** in Phase 1 — it is a placeholder that throws `NOT_IMPLEMENTED`. ZK proof acceptance criteria (#13) are moved to Phase 2. + +**What IS tested in Phase 1:** +- Instance chains with representation evolution (re-encoded elements) +- Instance selection strategies (latest, original, by-kind, by-repr-version) +- `addInstance()` with a mock "consolidated-proof" kind +- Chain integrity validation + +--- + +## Decision 10: Streaming Semantics — Lazy Resolution, Not Byte-Level Streaming + +**Context:** The reviewer (Finding 4.2) noted that true byte-level streaming is infeasible with a shared DAG. The IPFS researcher confirmed CAR supports sequential reading. + +**Decision:** Redefine "streaming-friendly" as: +1. The manifest is at the beginning of the serialized format (CAR root), enabling early knowledge of which tokens exist. +2. Elements can be **lazily resolved** (fetched on demand by CID from IPFS) rather than requiring the entire pool to be loaded. +3. CAR block ordering (manifest first, then BFS per token) enables progressive loading. + +True byte-level streaming of reassembly is NOT a goal. + +--- + +## Decision 11: Garbage Collection — Explicit Mark-and-Sweep + +**Context:** The reviewer (Finding 1.3) noted GC with shared elements is expensive. + +**Decision:** GC is explicit via `pkg.gc()`. It performs mark-and-sweep from all manifest roots. Not called automatically on `removeToken()`. For typical wallet sizes (100-1000 tokens, <5000 elements), a full mark-and-sweep takes <10ms. + +--- + +## Decision 12: "Append-Only" Wording Correction + +**Context:** The reviewer (Finding 6.1) identified a contradiction: TASK.md says proofs can be "updated in place" but the instance chain model says updates are append-only. + +**Decision:** Correct the language. All elements in the pool are immutable. "Updates" are new instances appended to the instance chain. The original element is never modified or removed. TASK.md will be updated to remove "updated in place" language. + +--- + +## Decision 13: API Cleanup — Remove addToken, Keep ingest + +**Context:** The reviewer (Finding 6.3) noted `ingest()` and `addToken()` appear to do the same thing. + +**Decision:** `addToken()` is removed. `ingest()` is the sole method for adding tokens to a package — it deconstructs, deduplicates, and updates the manifest. `ingestAll()` handles batch ingestion. There is no alias or convenience wrapper. + +--- + +## Decision 14: Module Placement in sphere-sdk + +**Context:** The architect proposed a top-level `uxf/` directory. + +**Decision:** Accepted. UXF lives at `sphere-sdk/uxf/` as a top-level module (not under `modules/`). It is platform-agnostic with no dependencies on `Sphere`, `PaymentsModule`, or transport. It gets its own tsup entry point (`@unicitylabs/sphere-sdk/uxf`). + +**File structure:** +``` +uxf/ +├── index.ts # Barrel exports +├── types.ts # All UXF type definitions +├── UxfPackage.ts # Package class +├── deconstruct.ts # Token → DAG decomposition +├── assemble.ts # DAG → Token reassembly +├── element-pool.ts # ElementPool class +├── instance-chain.ts # Instance chain management +├── hash.ts # Content hashing +├── verify.ts # Integrity verification +├── ipld.ts # IPLD/CAR import/export +└── errors.ts # Error types +``` + +--- + +## Summary: Phase 1 Implementation Scope + +| Component | Status | Notes | +|-----------|--------|-------| +| Element type taxonomy (12 types) | Defined | SmtPathSegment inlined in SmtPath | +| Element pool (in-memory Map) | Phase 1 | Content-addressed, dedup on insert | +| Deconstruction (ITokenJson → DAG) | Phase 1 | Recursive, mid-level granularity | +| Reassembly (DAG → ITokenJson) | Phase 1 | With integrity checks, cycle detection | +| Instance chains | Phase 1 | Mechanism + mock instances, no ZK/consolidation | +| Instance selection strategies | Phase 1 | latest, original, by-kind, by-repr, custom | +| Package serialization (JSON) | Phase 1 | For debugging and interchange | +| Package serialization (CAR) | Phase 1 | Primary binary format | +| Content hashing (dag-cbor + SHA-256) | Phase 1 | Via @ipld/dag-cbor | +| Manifest + indexes | Phase 1 | byTokenType, byCoinId, byStateHash | +| GC (mark-and-sweep) | Phase 1 | Explicit via gc() | +| merge() / diff() | Phase 1 | With instance chain conflict handling | +| verify() | Phase 1 | Hash verification + cycle check + chain validation | +| TxfToken adapter | Phase 1 | Thin conversion layer | +| Proof consolidation | Phase 2 | Requires aggregator cooperation | +| ZK proof substitution | Phase 2 | Requires ZK system | +| UxfStorageAdapter | Phase 2 | Replaces TxfStorageData for persistence | +| Wallet metadata in envelope | Phase 2 | _outbox, _tombstones, etc. | +| HAMT sharding for large pools | Phase 2 | Only needed at >10K elements | + +--- + +## Inter-Wallet Transfer Protocol Decisions + +> Cross-reference: [UXF-TRANSFER-PROTOCOL.md](UXF-TRANSFER-PROTOCOL.md) is the canonical spec for the decisions below. Older decisions in this document that conflict (notably Decision 2 "UXF does not depend on PaymentsModule" and Decision 6 last-writer-wins for proofs) are SUPERSEDED for the inter-wallet transfer flow. + +### Decision 10: Aggregator Threat Model — Faulty, Never Hostile + +The protocol assumes the L3 aggregator may be **faulty** (drops submissions, returns transient errors, briefly returns inconsistent state across nodes) but **never hostile** (does not actively forge proofs or collude with validators to rewrite history). Out-of-scope failure modes (active forgery, validator collusion, deliberate split-brain on different SMT roots) are NOT defended against. + +**Rationale**: defending against active forgery requires multi-aggregator consensus / fraud proofs — fundamentally different architecture. The current Unicity BFT layer is the trust anchor; if it is compromised, no application-layer protocol can compensate. Stating the boundary explicitly avoids accidental claims of stronger guarantees. + +**Implication**: poll-side `NOT_AUTHENTICATED` emits `transfer:trustbase-warning` (likely stale local trustBase), not `transfer:security-alert` (reserved for sustained-after-refresh failures in conservative mode — the rare case that breaches the threat boundary). + +### Decision 11: Class-Disjoint Asset Model (NFT vs Coin) + +Tokens classified at runtime as either **coin** (non-empty `coinData`) or **NFT** (empty/null `coinData` after zero-amount pruning). The two classes are **disjoint** — no token carries both fungible balances and a separable NFT identity. Coin tokens may be split via burn-then-mint (each output gets a fresh `tokenId`); NFT tokens cannot be split (the SDK's `TokenSplitBuilder` rejects empty-coinData inputs). + +**Rationale**: verified against `@unicitylabs/state-transition-sdk` source — there is no SDK primitive that produces a child token with the original `tokenId` while modifying `coinData`. Mixed-asset extraction (e.g., "send the NFT identity but leave the coins behind") is unimplementable on the current SDK. Class-disjointness aligns the protocol with what the SDK actually supports. + +**Implication**: NFT transfers are always whole-token (no split, no change); coin transfers may split. NFT cascades on chain-mode hard-fail are irrecoverable (non-fungible identity loss); the `confirmNftPending` flag forces explicit operator acknowledgment before sending pending-source NFTs. + +### Decision 12: Most-Recent-Proof Canonicalization + +Same `requestId` + same value (transactionHash + authenticator) can have **multiple valid proofs** across successive aggregator BFT rounds — the SMT grows with every round, so witness paths and `unicityCertificate` differ even though the proven leaf is identical. The protocol canonicalizes by selecting the proof from the **latest BFT round** (ties broken by first-observed-locally timestamp). + +**Rationale**: rejected lex-min-CID-as-canonical rule for proofs (which still applies to divergent-chain tie-breaks at §5.3 [D-conflict]) because it is meaningless for proofs — the value is the same; only the BFT-round metadata differs. Latest-round wins is the operationally correct rule. Supersedes Decision 6 ("last-writer-wins") for proof elements specifically. + +**Implication**: when a fresher proof arrives for an already-attached requestId (via merge or rescan), the local manifest entry is updated to the newer proof; the old proof element is tombstoned. Two proofs for the same `requestId` with **different values** is the explicit single-spend violation that triggers `transfer:security-alert` (out-of-scope per Decision 10). + +### Decision 13: Bundle Ingest Concurrency (16-Worker Default) + +Incoming UXF bundles are processed by a pool of `MAX_INGEST_WORKERS = 16` (configurable) parallel workers with a bounded ingest queue (default 256 entries). Per-tokenId mutexes coordinate cross-worker conflicts on the same `tokenId`. + +**Rationale**: a single rogue bundle (chain-mode token with K=64 unfinalized txs, slow-IPFS `uxf-cid` fetch, etc.) would otherwise serialize behind every other legitimate bundle, creating a DoS vector. With N workers, slow bundles consume one worker each; the other N−1 continue serving fresh arrivals. + +### Decision 14: `_audit` as a New Collection + +`NOT_OUR_CURRENT_STATE` and `UNSPENDABLE_BY_US` dispositions land in a NEW `_audit` collection (Wave T.3) — distinct from the existing `invalidTokens` (now `_invalid`) which holds cryptographically broken records. + +**Rationale**: structurally valid tokens we just can't spend (e.g., a token whose current state binds to a sibling instance with the same keys) are forensically distinct from cryptographically broken tokens. `_audit` is operationally promotable — a later transfer that makes the token ours triggers a periodic-rescan-driven promotion to active inventory; `_invalid` is terminal absent operator override. + +**Implication**: both collections use multi-representation keys: `${addr}.invalid.${tokenId}.${observedTokenContentHash}` and `${addr}.audit.${tokenId}.${observedTokenContentHash}`. The same `tokenId` may have multiple records (one per observed bundle). + +### Decision 15: Outbox CRDT — Three-Tier Partition + Override Stickiness + +The outbox state machine partitions states into three tiers for CRDT merge: **active** (worker progressing), **soft-terminal** (`failed-transient` — could resume), **hard-terminal** (`finalized | failed-permanent | expired`). Active beats soft-terminal; hard-terminal beats both — except when the active replica has `overrideApplied: true` (set by `payments.importInclusionProof()` operator override), which makes active `finalizing` win against `failed-permanent` regardless of Lamport. + +**Rationale**: rejected the simpler "monotonic LWW" because the state graph is not a total order (sibling terminal states `finalized` / `failed-permanent` / `failed-transient` would have no canonical winner). Override-stickiness prevents a stale replica's higher-Lamport `failed-permanent` from silently undoing an operator's recovery action. + +### Decision 16: Two-Set commitmentRequestIds (outstanding + completed) + +Outbox entries track instant-mode commitment requestIds in TWO sets: `outstandingRequestIds` (still being polled / submitted) and `completedRequestIds` (proof attached or hard-failed). On CRDT merge: `outstanding := union(A_outstanding, B_outstanding) - union(A_completed, B_completed)`. + +**Rationale**: rejected the simpler set-union form because it would re-add finalized requestIds to the outstanding pool whenever a stale replica merges, triggering re-submission. The two-set form preserves the "completed never un-completes" invariant. + +### Decision 17: Decision 2 ("UXF does not depend on PaymentsModule") Superseded for Transfer Flow + +The original Decision 2 stated UXF library is independent of PaymentsModule, with `UxfStorageAdapter` deferred to Phase 2. The inter-wallet transfer protocol (UXF-TRANSFER-PROTOCOL.md §4–§7) ties bundle construction, outbox state machine, and finalization workers directly to `PaymentsModule.send()`. The OrbitDB-backed Profile (PROFILE-ARCHITECTURE.md §10) is now the storage backbone for the transfer flow, NOT a future-phase `UxfStorageAdapter`. + +**Implication**: Decision 2 still holds for the UXF *package layer* (CAR / DAG / element decomposition is independent of PaymentsModule), but the *transfer protocol layer* is part of PaymentsModule. diff --git a/docs/uxf/DOMAIN-CONSTRAINTS.md b/docs/uxf/DOMAIN-CONSTRAINTS.md new file mode 100644 index 00000000..a7653842 --- /dev/null +++ b/docs/uxf/DOMAIN-CONSTRAINTS.md @@ -0,0 +1,613 @@ +# UXF Domain-Specific Implementation Constraints + +**Status:** Implementation guide for UXF deconstruction/reassembly +**Date:** 2026-03-26 + +This document captures every domain-specific constraint and pitfall that a generic TypeScript developer would miss when implementing UXF token decomposition and reassembly.

The package format MUST preserve this null value on round-trip — null is a valid encoded value, not "missing field." Decoders MUST treat `inclusionProof: null` as "transaction is unfinalized, awaits proof attachment via §5.5 finalization queue." The token's class (NFT vs coin per §4.1 canonical asset model) is determined at runtime from `coinData.length === 0` after zero-amount pruning at ingest. + +--- + +## 1. ITokenJson Field Mapping to UXF Elements + +### 1.1 Canonical Input Type: ITokenJson + +The canonical input is `ITokenJson` from `@unicitylabs/state-transition-sdk` (see Decision 1 in DESIGN-DECISIONS.md). Its structure is: + +```typescript +interface ITokenJson { + version: string; // "2.0" + state: ITokenStateJson; // current ownership state + genesis: IMintTransactionJson; // mint transaction + transactions: ITransferTransactionJson[]; // transfer history + nametags: ITokenJson[]; // recursive nametag tokens +} +``` + +**CRITICAL: ITokenJson vs TxfToken structural divergence.** The sphere-sdk `TxfToken` type describes a **different shape** for transfer transactions. In `ITokenJson` (SDK), transfers have `{ data: ITransferTransactionDataJson, inclusionProof }` where `data` contains `sourceState`, `recipient`, `salt`, etc. In `TxfToken` (sphere-sdk), transfers have `{ previousStateHash, newStateHash, predicate, inclusionProof }`. These are structurally incompatible. The `normalizeSdkTokenToStorage()` function casts between them via duck typing (`structuredClone` + `as any`). The UXF adapter must handle both shapes. + +### 1.2 Element-by-Element Field Mapping + +#### TokenRoot (0x01) + +| UXF Field | Source Path | Type Transformation | Edge Cases | +|-----------|------------|---------------------|------------| +| `tokenId` | `genesis.data.tokenId` | hex string -> `Uint8Array(32)` | Always 64-char hex. Never null. | +| `version` | `version` | string, keep as-is | Always `"2.0"` in production. Must round-trip exactly. | +| `genesis` | `genesis` | Deconstruct to GenesisTransaction element, store content hash | Always present. | +| `transactions` | `transactions` | Array of TransferTransaction content hashes | May be empty `[]`. Never null or undefined. | +| `state` | `state` | Deconstruct to TokenState element, store content hash | Always present. | +| `nametags` | `nametags` | Array of TokenRoot content hashes (recursive) | **May be `[]`, `undefined`, or contain full `ITokenJson` objects.** In TxfToken format, may be `string[]` (nametag names only, not token objects). | + +**Nametag pitfall:** When ingesting `TxfToken`, `nametags` is `string[]` (just names like `["alice"]`). When ingesting `ITokenJson`, `nametags` is `ITokenJson[]` (full recursive tokens). The adapter must detect which format it is. String nametags cannot be deconstructed into token sub-DAGs -- they carry no token data. The adapter must either: +- Reject string nametags and require the caller to provide full nametag tokens separately, or +- Accept string nametags but store them as a lightweight metadata annotation (not as TokenRoot elements), with a warning that nametag deduplication is not possible. + +#### GenesisTransaction (0x02) + +| UXF Field | Source Path | Type Transformation | Edge Cases | +|-----------|------------|---------------------|------------| +| `data` | `genesis.data` | Deconstruct to MintTransactionData, store content hash | Always present. | +| `inclusionProof` | `genesis.inclusionProof` | Deconstruct to InclusionProof, store content hash | Always present for valid tokens. In ITokenJson, the SDK requires it. **However**, tokens with `{ _pendingFinalization }` or `{ _placeholder: true }` in `sdkData` have no valid genesis proof -- these must be rejected by the ingestion layer. | +| `destinationState` | **DERIVED** (see Section 3) | Deconstruct to TokenState, store content hash | Not directly available in ITokenJson. Must be derived. | + +#### MintTransactionData (0x04) + +| UXF Field | Source Path | Type Transformation | Edge Cases | +|-----------|------------|---------------------|------------| +| `tokenId` | `genesis.data.tokenId` | hex string -> `Uint8Array(32)` | Always 64-char hex. | +| `tokenType` | `genesis.data.tokenType` | hex string -> `Uint8Array(32)` | Always 64-char hex. Nametag tokens use type `f8aa13834268d29355ff12183066f0cb902003629bbc5eb9ef0efbe397867509`. | +| `coinData` | `genesis.data.coinData` | `[string, string][]` -> keep as array of `[text, text]` | In ITokenJson: `TokenCoinDataJson = [string, string][]`. May be `null` in the SDK type (`IMintTransactionDataJson.coinData: TokenCoinDataJson | null`). Nametag tokens have `coinData: []` (empty array) or `null`. For CBOR encoding, `null` should be stored as empty array `[]`. | +| `tokenData` | `genesis.data.tokenData` | `string | null` -> `Uint8Array` (empty if null) | For fungible tokens: usually `""` or `null`. For nametag tokens: contains the nametag string data. **Wave H — null hash canonicalization (SPEC change):** at the hash boundary, `''`, `null`, and `Uint8Array(0)` for byte-fields are treated as canonically equivalent and encode to CBOR null (0xf6). This unifies the "no value" representation across SDKs and prevents two compliant implementations from computing different hashes for the same logical token. Wire serialization (JSON/CAR) is unchanged — what the user passes in is what comes back out, modulo the canonical normalization on round-trip. | +| `salt` | `genesis.data.salt` | hex string -> `Uint8Array(32)` | Always 64-char hex. Never null. | +| `recipient` | `genesis.data.recipient` | string, keep as text | `"DIRECT://..."` format (~80 chars). Never null. | +| `recipientDataHash` | `genesis.data.recipientDataHash` | hex string -> `Uint8Array(32)` or `null` | Usually `null`. When present, 64-char hex. | +| `reason` | `genesis.data.reason` | complex object or `null` | **THIS IS THE SPLIT TOKEN PITFALL.** See Section 5.3. For regular mints: `null`. For split tokens: `ISplitMintReasonJson` -- a complex nested object containing a full `ITokenJson` parent token plus proofs. The spec says `text / null` but this is wrong for split tokens. See detailed analysis below. | + +#### TransferTransaction (0x03) + +| UXF Field | Source Path (ITokenJson) | Source Path (TxfToken) | Edge Cases | +|-----------|-------------------------|----------------------|------------| +| `sourceState` | `transactions[n].data.sourceState` | **DERIVED** from `previousStateHash` | In ITokenJson: `sourceState: ITokenStateJson` is inline.

See Section 3.2. | +| `data` | `transactions[n].data` (extract recipient, salt, etc.) | `transactions[n].data` (optional `Record`) | **In ITokenJson format:** `data` contains `sourceState`, `recipient`, `salt`, `recipientDataHash`, `message`, `nametags`. These must be decomposed. **In TxfToken format:** `data` is an optional opaque record, and the predicate is at top level. | +| `inclusionProof` | `transactions[n].inclusionProof` | `transactions[n].inclusionProof` | `null` for uncommitted/pending transactions. Must store as `null` child reference. | +| `destinationState` | **DERIVED** | **DERIVED** | See Section 3.2. | + +**CRITICAL structural divergence for transfers:** + +In `ITransferTransactionJson` (SDK canonical): +```typescript +{ + data: { + sourceState: { predicate: string, data: string | null }, + recipient: string, + salt: string, + recipientDataHash: string | null, + message: string | null, + nametags: ITokenJson[] + }, + inclusionProof: IInclusionProofJson +} +``` + +In `TxfTransaction` (sphere-sdk storage): +```typescript +{ + previousStateHash: string, // hash of source state + newStateHash?: string, // hash of destination state (derived, optional) + predicate: string, // hex CBOR predicate of destination state + inclusionProof: TxfInclusionProof | null, + data?: Record // optional extra data +} +``` + +**The UXF deconstruction layer MUST detect which format a transfer transaction is in.** Detection strategy: +- If `tx.data?.sourceState` exists -> ITokenJson format +- If `tx.previousStateHash` exists -> TxfToken format +- Both may be present (duck-typed cast) + +#### TransferTransactionData (0x05) + +| UXF Field | Source Path (ITokenJson) | Type Transformation | Edge Cases | +|-----------|-------------------------|---------------------|------------| +| `recipient` | `transactions[n].data.recipient` | string, keep as text | Always present in ITokenJson format. | +| `salt` | `transactions[n].data.salt` | hex string -> `Uint8Array(32)` | Always present. | +| `recipientDataHash` | `transactions[n].data.recipientDataHash` | hex string -> `Uint8Array(32)` or `null` | Usually null. | +| `extraData` | n/a | `null` | The `message` field from `ITransferTransactionDataJson` could map here, but it's `string | null` in the SDK, not a key-value map. The `nametags` from `ITransferTransactionDataJson` are handled separately (as child TokenRoot refs on the parent token). | + +**Nametags in transfer data:** `ITransferTransactionDataJson.nametags` is `ITokenJson[]` -- nametag tokens embedded in transfer data. These are the same nametags that appear in the top-level `ITokenJson.nametags`. UXF deduplicates them as shared TokenRoot elements. During deconstruction, extract nametags from transfer data and deduplicate with the top-level nametags array. + +**Message field:** `ITransferTransactionDataJson.message` is `string | null`. This field is not captured by the current UXF `TransferTransactionData` spec which has `extraData: map / null`. Implementation should store message as `{ "message": "" }` in extraData, or the spec should add an explicit `message` field. + +#### TokenState (0x06) + +| UXF Field | Source Path | Type Transformation | Edge Cases | +|-----------|------------|---------------------|------------| +| `predicate` | `state.predicate` or `transactions[n].data.sourceState.predicate` | hex string -> `Uint8Array` (opaque CBOR bytes) | Always present. Variable length (~340-400 hex chars). Keep as opaque bytes -- do NOT decode the CBOR predicate structure. | +| `data` | `state.data` or `transactions[n].data.sourceState.data` | `string | null` -> `Uint8Array` (empty if null/empty string) | Usually `null` or `""` for fungible tokens. **Wave H:** at the hash boundary, `''`, `null`, and `Uint8Array(0)` are canonically equivalent and encode to CBOR null. See `tokenData` row for the full rationale. | + +#### InclusionProof (0x08) + +| UXF Field | Source Path | Type Transformation | Edge Cases | +|-----------|------------|---------------------|------------| +| `authenticator` | `inclusionProof.authenticator` | Deconstruct to Authenticator element, store content hash | **Can be `null` in `IInclusionProofJson`.** The SDK type says `authenticator: IAuthenticatorJson | null`.

See Section 2.3. | + +--- + +## 2. Hex and Binary Conversion Rules + +### 2.1 General Rule + +The SDK stores all binary data as hex strings. UXF elements encoded in CBOR store binary data as `Uint8Array` (CBOR bstr). The conversion is: + +```typescript +function hexToBytes(hex: string): Uint8Array { + const bytes = new Uint8Array(hex.length / 2); + for (let i = 0; i < hex.length; i += 2) { + bytes[i / 2] = parseInt(hex.substr(i, 2), 16); + } + return bytes; +} +``` + +### 2.2 UnicityCertificate: Hex-Encoded CBOR Treatment + +The `unicityCertificate` field in `IInclusionProofJson` is a hex string encoding CBOR bytes. These CBOR bytes contain a tagged structure (tag 1007) with sub-structures (tags 1001, 1008). + +**Decision:** Store as **opaque bytes** in UXF. The `UnicityCertificate` element's `rawCbor` field contains the decoded bytes (hex -> Uint8Array). Do NOT attempt to decode/re-encode the internal CBOR structure. Reasons: +1. The certificate is produced and signed by the BFT layer -- its internal structure is immutable. +2. Preserving exact bytes is essential for content hash stability. +3. The certificate is the primary deduplication target: byte-level identity determines dedup. + +**Conversion:** +``` +Storage: "a4d907ef..." (hex string in ITokenJson) +UXF CBOR: bstr(0xa4, 0xd9, 0x07, 0xef, ...) (raw bytes) +Reassembly: convert back to hex string +``` + +**Round-trip invariant:** `bytesToHex(hexToBytes(original)) === original.toLowerCase()`. Ensure hex is lowercased before storage to guarantee deterministic content hashes. + +### 2.3 SmtPath `path` Field: NOT Hex + +The `path` field in `ISparseMerkleTreePathStepJson` is a **string representation of a bigint**, NOT a hex string. It represents a bit pattern for the L/R direction in the SMT. + +Example values: `"0"`, `"1"`, `"340282366920938463463374607431768211456"`. + +In the SDK, `SparseMerkleTreePathStep.path` is a `bigint`. The JSON form is its decimal string representation via `bigint.toString()`. + +**For UXF CBOR encoding:** Store as bytes (`Uint8Array`). The `path` value must be converted from its string representation to bytes. Use the string's UTF-8 encoding to preserve the exact value. Alternatively, treat as a CBOR bigint/bignum. The simplest correct approach is to store the `[data, path]` tuple as `[bstr, bstr]` where `path` bytes are the UTF-8 encoding of the decimal string, since the spec says `segments: array<[bytes, bytes]>`. + +**PITFALL:** If you interpret `path` as hex and call `hexToBytes()`, you will corrupt the data. The string `"1"` is the number 1, not the byte `0x01`. + +**Recommendation:** Store `path` as a CBOR unsigned integer or bignum. If the value exceeds CBOR's native integer range (which it can -- SMT paths can be up to 2^256), use CBOR tag 2 (positive bignum) with the byte representation of the bigint. This is the most space-efficient and semantically correct encoding: + +```typescript +// Convert path string to bigint, then to CBOR bignum bytes +const pathBigint = BigInt(pathString); +const pathBytes = bigintToBytes(pathBigint); // big-endian, minimal encoding +``` + +### 2.4 Fields That Stay as Strings + +| Field | Why String | CBOR Type | +|-------|-----------|-----------| +| `version` | Semantic version string | `tstr` | +| `recipient` | Address format (`DIRECT://...`) | `tstr` | +| `algorithm` | Algorithm name (`"secp256k1"`) | `tstr` | +| `coinData[n][0]` | Coin ID (hex string kept as text for portability) | `tstr` | +| `coinData[n][1]` | Amount (decimal string for arbitrary precision) | `tstr` | +| `reason` | Reason string or null | `tstr / null` | +| `kind` | Instance kind label | `tstr` | + +### 2.5 Fields That Become Bytes + +| Field | Source Format | CBOR Type | Length | +|-------|-------------|-----------|--------| +| `tokenId` | 64-char hex | `bstr .size 32` | Fixed 32 | +| `tokenType` | 64-char hex | `bstr .size 32` | Fixed 32 | +| `salt` | 64-char hex | `bstr .size 32` | Fixed 32 | +| `publicKey` | 66-char hex | `bstr .size 33` | Fixed 33 | +| `signature` | ~140-144 char hex | `bstr` | Variable 70-72 | +| `stateHash` | 64-char hex | `bstr .size 32` | Fixed 32 | +| `transactionHash` | 64-char hex | `bstr .size 32` | Fixed 32 | +| `root` (SmtPath) | 64-char hex | `bstr .size 32` | Fixed 32 | +| `predicate` (TokenState) | variable hex | `bstr` | Variable ~170-200 | +| `data` (TokenState) | hex string or null | `bstr` | Variable, usually 0 | +| `tokenData` | hex string or null | `bstr` | Variable | +| `recipientDataHash` | 64-char hex or null | `bstr .size 32 / null` | Fixed 32 or null | +| `rawCbor` (UnicityCertificate) | hex string | `bstr` | Variable ~500-2000 | +| `segments[n].data` (SmtPath) | 64-char hex or null | `bstr / null` | 32 or null | + +### 2.6 Normalization Before Hashing + +The SDK's `normalizeToHex()` function handles three input shapes: +1. Hex string -> pass through +2. `{ bytes: Uint8Array | number[] }` -> convert to hex +3. `{ type: "Buffer", data: number[] }` -> convert to hex + +When ingesting tokens, call `normalizeSdkTokenToStorage()` first to ensure all byte fields are hex strings, then convert hex to `Uint8Array` for CBOR encoding. This two-step normalization ensures consistent content hashes regardless of input format. + +--- + +## 3. State Derivation + +### 3.1 Genesis Destination State + +The genesis destination state is the token's state immediately after minting. It is **not an explicit field** in `ITokenJson`. It must be derived. + +**Derivation rule for ITokenJson format:** + +If the token has zero transfer transactions, the genesis destination state IS the current `state`: +``` +genesis.destinationState = token.state +``` + +If the token has transfer transactions, the genesis destination state is the `sourceState` of the FIRST transfer transaction: +``` +genesis.destinationState = token.transactions[0].data.sourceState +``` + +**Derivation rule for TxfToken format:** + +TxfToken does not carry `sourceState` inline -- it only has `previousStateHash`. To derive the actual TokenState for the genesis destination: +- If zero transactions: `genesis.destinationState = token.state` +- If transactions exist: the genesis destination state CANNOT be derived from TxfToken alone (only its hash is available as `transactions[0].previousStateHash`). This is why ITokenJson is the canonical input -- it carries the full sourceState. + +**PITFALL:** If the input is TxfToken with transactions, you cannot construct the genesis destinationState TokenState element. The adapter from TxfToken to ITokenJson must either: +1. Re-parse the token through `SdkToken.fromJSON()` which reconstructs the full state chain, or +2. Store a hash-only reference and mark the element as unresolvable. + +### 3.2 Transfer Transaction Source and Destination States + +For each transfer transaction `transactions[n]`: + +**sourceState (where the token was before this transition):** +- `n == 0`: sourceState = genesis destination state (see 3.1) +- `n > 0`: sourceState = destination state of `transactions[n-1]` + +In ITokenJson: `transactions[n].data.sourceState` is available inline. +In TxfToken: only `transactions[n].previousStateHash` is available. + +**destinationState (where the token is after this transition):** +- Not directly stored in either format. +- If `n < transactions.length - 1`: destinationState = `transactions[n+1].data.sourceState` (in ITokenJson) +- If `n == transactions.length - 1` (last transaction): destinationState = `token.state` (current state) + +**Algorithm for ITokenJson:** +```typescript +function deriveTransactionStates(token: ITokenJson) { + const states: ITokenStateJson[] = []; + + // Genesis destination state + if (token.transactions.length > 0) { + states.push(token.transactions[0].data.sourceState); + } else { + states.push(token.state); + } + + // Transfer destination states + for (let i = 0; i < token.transactions.length; i++) { + if (i < token.transactions.length - 1) { + states.push(token.transactions[i + 1].data.sourceState); + } else { + states.push(token.state); // last tx destination = current state + } + } + + return states; // states[0] = genesis dest, states[n+1] = tx[n] dest +} +``` + +### 3.3 State Hash vs Content Hash + +**Two different hash functions operate on TokenState:** + +1. **SDK state hash:** Computed by `TokenState.calculateHash()` in the SDK. Used in authenticator `stateHash`, in `previousStateHash`/`newStateHash` TXF fields, and for `RequestId` derivation. This is a protocol-level hash with SDK-specific serialization. + +2. **UXF content hash:** `SHA-256(canonical_cbor(TokenState_element))`. Used for content addressing in the element pool and child references. + +These hashes are **completely different values** for the same logical state. Do not confuse them. + +The `authenticator.stateHash` stores the SDK state hash, NOT the UXF content hash. During reassembly, the SDK state hash is preserved verbatim in the authenticator element. The UXF content hash is used only for pool addressing. + +--- + +## 4. Nametag Token Handling + +### 4.1 ITokenJson Nametag Structure + +In `ITokenJson`, `nametags` is `ITokenJson[]` -- each nametag is a complete recursive token: + +```json +{ + "version": "2.0", + "state": { "predicate": "", "data": null }, + "genesis": { + "data": { + "tokenId": "<64 hex>", + "tokenType": "f8aa13834268d29355ff12183066f0cb902003629bbc5eb9ef0efbe397867509", + "coinData": [], + "tokenData": "", + "salt": "<64 hex>", + "recipient": "DIRECT://...", + "recipientDataHash": null, + "reason": null + }, + "inclusionProof": { /* full proof */ } + }, + "transactions": [], + "nametags": [] +} +``` + +Key characteristics: +- `tokenType` is always `f8aa1383...7509` (the nametag token type constant) +- `coinData` is always `[]` (empty) or `null` +- `transactions` is always `[]` (nametags are never transferred) +- `nametags` is always `[]` (no recursive nametags-of-nametags) +- `tokenData` contains the nametag name as data + +### 4.2 TxfToken Nametag Structure + +In `TxfToken`, `nametags` is `string[] | undefined` -- just the names: + +```json +{ + "nametags": ["alice", "bob"] +} +``` + +The actual nametag token data is stored separately in `TxfStorageData._nametag` / `_nametags` as `NametagData`: + +```typescript +interface NametagData { + name: string; // "alice" + token: object; // The full ITokenJson nametag token + timestamp: number; + format: string; + version: string; +} +``` + +### 4.3 Detection and Adapter Logic + +To detect which format nametags are in: + +```typescript +function isITokenJsonNametags(nametags: unknown): nametags is ITokenJson[] { + return Array.isArray(nametags) && + nametags.length > 0 && + typeof nametags[0] === 'object' && + nametags[0] !== null && + 'genesis' in nametags[0]; +} + +function isStringNametags(nametags: unknown): nametags is string[] { + return Array.isArray(nametags) && + (nametags.length === 0 || typeof nametags[0] === 'string'); +} +``` + +### 4.4 TxfToken Adapter Requirements + +When ingesting from `TxfToken`: +1. Check if `nametags` is `string[]`. If so, resolve full nametag tokens from the `NametagData` storage. +2. The caller must provide the `NametagData[]` alongside the `TxfToken` for full nametag deduplication. +3. If nametag tokens are not available (string nametags only, no NametagData), the UXF package cannot deduplicate nametags. Store the string names as metadata in the TokenRoot element (not as child references). + +### 4.5 Nametags in Transfer Transactions + +`ITransferTransactionDataJson` also contains `nametags: ITokenJson[]`. These are nametag tokens that were included in the transfer data to prove the sender/recipient identity for PROXY address resolution. + +**These are the same nametag tokens** that appear in the top-level `ITokenJson.nametags`. During deconstruction, all nametag tokens (from top-level and from transfer transaction data) should be pooled and deduplicated. The content hash ensures identical nametag tokens are stored only once. + +**PITFALL:** When reassembling, the nametags must be placed back in BOTH locations: +- Top-level `ITokenJson.nametags` +- Inside each `ITransferTransactionDataJson.nametags` that originally contained them + +The deconstruction must record which transfer transactions referenced which nametags. One approach: during deconstruction, the TransferTransactionData element's `extraData` field stores a `_nametagRefs` array of TokenRoot content hashes. + +--- + +## 5. Edge Cases and Invariants + +### 5.1 Pending/Uncommitted Transactions + +A token may have the last transaction with `inclusionProof: null`. This means the state transition has been submitted but not yet confirmed by the aggregator. + +**Impact on UXF:** +- The TransferTransaction element has `inclusionProof: null` (null child reference). +- No Authenticator, SmtPath, or UnicityCertificate elements are created for this transaction. +- The `data` child reference may also be null if the transfer data hasn't been finalized. +- The `destinationState` is still derivable (it's `token.state` if this is the last transaction). +- **During reassembly**, null inclusionProof must round-trip correctly. The reassembled `ITokenJson` must have `inclusionProof: null` in the corresponding `ITransferTransactionJson` (via null in the authenticator and transactionHash fields, with an empty/default merkleTreePath and unicityCertificate). + +**WAIT -- ITransferTransactionJson does NOT support null inclusionProof.** Looking at the SDK types: + +```typescript +interface ITransferTransactionJson { + readonly data: ITransferTransactionDataJson; + readonly inclusionProof: IInclusionProofJson; // NOT nullable! +} +``` + +But `TxfTransaction` does: +```typescript +interface TxfTransaction { + inclusionProof: TxfInclusionProof | null; // nullable +} +``` + +**This means pending transactions exist in TxfToken format but NOT in valid ITokenJson format.** The SDK's `Token.fromJSON()` likely fails on null inclusionProof. Pending tokens should be handled by either: +1. Rejecting tokens with pending transactions at ingestion time (recommended for Phase 1). +2. Storing the pending transaction as a special-case element with all-null proof fields. + +**Recommendation:** Phase 1 should reject tokens with `inclusionProof === null` in any transaction with a clear error message. These tokens are in-flight and not yet suitable for archival/exchange. + +### 5.2 Placeholder and Pending Finalization Tokens + +The sphere-sdk stores sentinel values in `sdkData`: +- `{ _placeholder: true }` -- Token slot reserved, no actual data +- `{ _pendingFinalization: { ... } }` -- Token awaiting V5 finalization + +**These must be rejected by UXF ingestion.** They have no valid genesis data and cannot be deconstructed into a DAG. + +Detection: +```typescript +function isPlaceholderOrPending(data: unknown): boolean { + if (!data || typeof data !== 'object') return true; + const obj = data as Record; + return !!obj._placeholder || !!obj._pendingFinalization; +} +``` + +### 5.3 Split Tokens (Mint with Reason) + +When a token is split (for partial transfers), the resulting tokens have `genesis.data.reason` set to an `ISplitMintReasonJson` object: + +```typescript +interface ISplitMintReasonJson { + type: "TOKEN_SPLIT"; + token: ITokenJson; // Full parent token that was split + proofs: ISplitMintReasonProofJson[]; // Aggregation + coin tree proofs +} + +interface ISplitMintReasonProofJson { + coinId: string; + aggregationPath: ISparseMerkleTreePathJson; // Plain SMT path + coinTreePath: ISparseMerkleSumTreePathJson; // Sum SMT path (different type!) +} +``` + +**CRITICAL:** The `reason` field contains a full recursive `ITokenJson` parent token. This is another deduplication opportunity -- if multiple split tokens share the same parent, the parent token sub-DAG is stored once. + +**The UXF spec says `reason: text / null`** which is INCORRECT for split tokens. The implementation must handle: +1. `null` -- regular mint, no reason +2. A string -- future use (the spec's text type) +3. An `ISplitMintReasonJson` object -- split token with embedded parent token and proofs + +**For Phase 1:** Store the reason as opaque CBOR-encoded bytes. If it's an object (split reason), serialize it via dag-cbor and store as `bstr`. The parent token within the reason can optionally be recursively deconstructed for deduplication. This is a significant win: if a 100-token split creates 100 child tokens, each child embeds the same parent token in its reason field. Without dedup: 100 copies of parent. With dedup: 1 copy. + +**SparseMerkleSumTreePath:** The split reason proofs use a **Sum Merkle Tree path**, not a plain one. This is a different type (`ISparseMerkleSumTreePathJson`) with different step structure. UXF does not define a SumSmtPath element type. For Phase 1, store these proofs as opaque bytes within the reason field. + +### 5.4 Tokens with Zero Transactions + +Common case: a freshly minted token that has never been transferred. + +``` +token.transactions = [] +``` + +**Impact:** +- TokenRoot `transactions` field is empty array `[]`. +- Genesis destination state = `token.state` (current state). +- The token has exactly 1 inclusion proof (genesis). +- Element count: ~8-10 elements (TokenRoot, GenesisTransaction, MintTransactionData, InclusionProof, Authenticator, SmtPath, UnicityCertificate, TokenState x1-2). + +### 5.5 Empty Nametags Array + +Most tokens have `nametags: []`. This is the normal case for tokens transferred via DIRECT address (not PROXY). + +**Impact:** TokenRoot `nametags` field is empty array `[]`. No nametag sub-DAGs are created. The CBOR encoding uses `0x80` (empty array), NOT null or omitted. + +### 5.6 Maximum Realistic Sizes + +| Metric | Typical | Maximum Observed | +|--------|---------|-----------------| +| Transactions per token | 0-5 | ~50 (heavily traded token) | +| Nametags per token | 0-2 | ~5 (multi-nametag user) | +| Elements per token | 8-35 | ~350 (50 txns * 7 elements each) | +| Tokens per wallet | 10-100 | ~1000 | +| Elements per package | 100-3500 | ~50,000 (1000 tokens) | +| Token JSON size | 6-18 KB | ~500 KB (50 txns, split token with reason) | +| Nametag token size | 5-8 KB | ~10 KB | +| Unicity certificate hex | 1-4 KB | ~8 KB (many validators) | +| SMT path steps | 10-40 | ~60 | + +### 5.7 Hex String Case Sensitivity + +The SDK uses **lowercase hex** throughout. The `normalizeToHex()` function produces lowercase. However, some SDK methods return mixed-case hex (e.g., `DataHash.toJSON()`). + +**UXF MUST normalize all hex strings to lowercase before:** +1. Converting to bytes (for content hash stability) +2. Using as map keys (for dedup) +3. Storing in manifest or indexes + +Failure to lowercase will cause identical binary content to produce different content hashes, breaking deduplication silently. + +### 5.8 TxfToken `_integrity` Field + +```typescript +interface TxfIntegrity { + genesisDataJSONHash: string; + currentStateHash?: string; +} +``` + +This is a TXF-only field for wallet-level integrity checking. It is NOT part of ITokenJson and MUST NOT be included in UXF elements. Ignore it during deconstruction. During reassembly back to TxfToken format (for sphere-sdk integration), it can be recomputed. + +### 5.9 Authenticator and TransactionHash Coupling + +In `IInclusionProofJson`: +- `authenticator: IAuthenticatorJson | null` +- `transactionHash: string | null` + +These are **coupled**: both are null or both are non-null. The SDK enforces this in the `InclusionProof` constructor: "Error if authenticator and transactionHash are not both set or both null." + +If authenticator is null, it means the proof is a non-inclusion proof (the token ID was NOT found in the SMT for that round). This is used during validation, not during normal token storage. UXF should never encounter a stored token with null authenticator in a committed transaction. + +### 5.10 CoinData Format Variations + +`IMintTransactionDataJson.coinData` is `TokenCoinDataJson | null` where `TokenCoinDataJson = [string, string][]`. + +Observed patterns: +- Normal fungible token: `[["<64-char coinId hex>", "1000000"]]` +- Multi-coin token: `[["", "500"], ["", "300"]]` (rare but supported) +- Nametag token: `[]` or `null` +- Zero-value token: `[["", "0"]]` (split remainder) + +**For CBOR encoding:** Normalize `null` to `[]`. Store as `array<[tstr, tstr]>`. The coinId is a hex string stored as text (NOT converted to bytes), because the SDK treats it as an opaque identifier string in the JSON form. + +--- + +## Summary of Critical Pitfalls + +1. **ITokenJson vs TxfToken transfer transaction shape** -- fundamentally different field layouts. Must detect and handle both. +2. **Nametags: recursive tokens vs string names** -- detect format, require full tokens for dedup. +3. **Genesis destinationState is not in the source data** -- must be derived from transaction chain. +4. **SmtPath `path` is a decimal bigint string, NOT hex** -- do not call hexToBytes on it. +5. **Split token `reason` is a complex object, not text** -- contains a full recursive ITokenJson parent token. +6. **Pending transactions have null inclusionProof** -- reject in Phase 1. +7. **Placeholder/pendingFinalization sentinels in sdkData** -- reject at ingestion. +8. **Hex case sensitivity** -- lowercase normalize before hashing or comparing. +9. **SDK state hash != UXF content hash** -- completely different computations, do not confuse. +10. **Message field in TransferTransactionData** -- exists in ITokenJson but not in UXF TransferTransactionData spec; needs mapping decision. +11. **Nametags appear in both top-level AND transfer transaction data** -- must deduplicate across both locations and restore to both on reassembly. +12. **UnicityCertificate is hex-encoded CBOR** -- decode hex to bytes but do NOT re-encode the inner CBOR. \ No newline at end of file diff --git a/docs/uxf/HIERARCHICAL-ADDRESSABILITY.md b/docs/uxf/HIERARCHICAL-ADDRESSABILITY.md new file mode 100644 index 00000000..9aa04ae8 --- /dev/null +++ b/docs/uxf/HIERARCHICAL-ADDRESSABILITY.md @@ -0,0 +1,473 @@ +# Hierarchical Addressability + +**Tracking issue:** [#200 — Hierarchical addressability: unify pin/fetch model +across profile, bundles, tokens, sub-token components][issue-200] + +[issue-200]: https://github.com/unicity-sphere/sphere-sdk/issues/200 + +This document describes the canonical IPFS storage layout the SDK +produces for every content-addressed artifact (profile snapshots, +bundle CARs, token DAGs, and sub-token components) and the per-codec +`dag/put` invariants that make the layout durable across Kubo +deployments. + +## TL;DR + +1. **Every component is individually addressable by its own CID.** + The envelope, the manifest, every token root, and every sub-token + element (genesis, predicate, coinData, each transition, each proof) + is a separate dag-cbor block reachable via a single `block/get` once + pinned. +2. **Composite artifacts are DAGs whose nodes are linked by CID.** No + opaque concatenations, no inline blobs. `manifest.tokens` is a + `tokenId → CID` map; element children are `CID` references (Tag 42 + in dag-cbor encoding); the envelope holds a single `manifest` CID + link. +3. **Repeating sub-components dedup automatically.** Byte-identical + element bytes produce byte-identical CIDs (sha-256 + canonical + dag-cbor).

The trade-off +is one HTTP round-trip per block; the SDK can parallelise if latency +becomes a concern. + +## Why this model + +### Goal: dedup at every layer + +Before Phase 2 (PR landed in commit f938e4c), the SDK pinned each +bundle CAR as a **single raw block** (`pinToIpfs(carBytes)` with raw +codec, CID = `sha256(carBytes)`). Consequences: + +- A bundle that re-published the same token N+1 times across N+1 + send/receive cycles produced N+1 distinct raw-CID blobs on IPFS even + though all but one byte of content was repeated. +- Sub-token components (predicates, types, proofs) were never + individually addressable. Recipients could not verify a single token + in isolation. + +Phase 2 migrated the bundle path to `pinCarBlocksToIpfs` + per-block +`dag/put`. The block-level dedup payoff is realised immediately at the +storage layer; the architectural payoff (per-token / per-sub-element +addressability) is realised by the existing canonical +`uxf/ipld.ts:exportToCar` builder, which already emits a hierarchical +DAG with CID links between layers. + +### Goal: partial recovery + +Once profile snapshots and bundle CARs share the hierarchical model +(Phase 4), a wallet can fetch the snapshot root, decode the bundle CID +list, and selectively fetch only the bundles relevant to its tracked +addresses. Likewise, a recipient that only needs one token from a +multi-token bundle can fetch that token's root CID directly and walk +its subtree without paying for the sibling tokens' blocks. + +### Goal: forward-compat with new sub-component types + +Future SDK versions might add new sub-token components (e.g. richer +proofs, multi-issuer signatures, …). Because every element is its own +content-addressed block, adding a new element type does not change the +CIDs of existing elements. Old recipients ignore unknown CIDs in +unfamiliar fields and continue to verify the known sub-tree. The +manifest's `tokens` map is the only fixed interop surface. + +## Determinism — what defeats dedup + +Dedup payoff is realized **only when content is byte-identical**. +Anything that introduces non-determinism into the serialisation +defeats it: + +- **Timestamps in element bodies.** Avoid `Date.now()` inside any + element content. Bundle envelopes carry timestamps deliberately and + are bundle-unique by design; element bodies must not. +- **Randomised salts that vary per emit.** A salt MUST be fixed by the + underlying token state, not regenerated each export.

The primary input remains `ITokenJson`. + + **Important structural difference:** `ITokenJson` uses `genesis.destinationState` (the post-genesis TokenState), while `TxfTransaction` uses `previousStateHash`/`newStateHash` (derived hash strings) and `predicate` (string). The deconstruction must handle both structural representations -- see the TxfToken adapter (WU-15). + + For the canonical `ITokenJson` path, the decomposition follows ARCH 4.1 exactly: + + Functions to implement: + + 1. `deconstructToken(pool: ElementPool, token: ITokenJson): ContentHash` -- main entry point (ARCH 4.3).

If string, encode as UTF-8 bytes. If null, store as null. + - Before deconstructing, check for sentinel values: if input has `_placeholder === true` or `_pendingFinalization` property, throw `UxfError('INVALID_PACKAGE', 'Cannot ingest placeholder or pending finalization tokens')`. + - When deconstructing TransferTransactionData, if the source ITokenJson transfer has `data.nametags[]`, recursively deconstruct each nametag token and store their root hashes as a `nametagRefs: ContentHash[]` field in TransferTransactionData content. + - All hex string content fields from the input token MUST be lowercased via `.toLowerCase()` before storing in element content.

OrbitDB + +**Current state:** OrbitDB v2.x (published as `@orbitdb/core`) is actively maintained with monthly updates through 2025. It migrated from the deprecated js-ipfs to Helia. It is funded by community donations and does not have corporate backing or a token. + +**Architecture:** OrbitDB builds databases on top of an immutable, append-only OpLog using Merkle-CRDTs. Libp2p PubSub propagates operations to peers. Every write is an IPLD-encoded operation appended to the log; the current state is derived by replaying the log. + +**Database types:** `events` (append-only log), `documents` (JSON indexed by key), `keyvalue`, `keyvalue-indexed` (KV backed by a LevelDB index for faster reads). + +**API:** +```javascript +import { createOrbitDB } from '@orbitdb/core' +const orbitdb = await createOrbitDB({ ipfs: heliaInstance }) +const db = await orbitdb.open('my-profile', { type: 'keyvalue' }) +await db.put('displayName', 'Alice') +const name = await db.get('displayName') +``` + +**TypeScript:** No first-class TypeScript types ship with `@orbitdb/core`. Community typings exist but lag behind releases. + +**Browser:** Works in browsers (Helia + libp2p in-browser). Bundle size is significant (~500KB+ gzipped with all libp2p transports). + +**Consistency:** Eventually consistent via Merkle-CRDTs. Concurrent writes to the same key are resolved by OpLog merge (last-writer-wins by default). No strong consistency guarantees. Replication depends on peers being online simultaneously or using the Voyager replication service (currently in testing). + +**Verdict for UXF wallet profiles:** Overly heavy for simple profile KV storage. Pulls in full Helia + libp2p stack. The CRDT machinery is valuable for multi-device sync but adds complexity. The lack of TypeScript types is a concern. Consider only if peer-to-peer real-time sync between wallet instances is a hard requirement. + +--- + +### 2. Helia + libp2p + +**What it is:** Helia is the official TypeScript IPFS implementation, replacing the deprecated js-ipfs. It is lean and modular: you compose a node from a blockstore, a datastore, and networking transports. + +**Storing a JSON document:** +```typescript +import { createHelia } from 'helia' +import { json } from '@helia/json' +import { dagCbor } from '@helia/dag-cbor' + +const helia = await createHelia() +const j = json(helia) +const cid = await j.add({ displayName: 'Alice', avatar: 'Qm...' }) +// cid is the content-addressed identifier +const profile = await j.get(cid) // { displayName: 'Alice', ... } +``` + +For structured data, `@helia/dag-cbor` is more compact and IPLD-native than `@helia/json`. + +**Persistent blockstore in browser:** Use `blockstore-idb` (IndexedDB-backed) for persistence across sessions. In Node.js, use `blockstore-fs` or `blockstore-level`. + +**Can it be a KV store?** Not natively. Helia is a content-addressed blockstore (CID -> bytes). To build a KV store, you would store a DAG-CBOR map, get its CID, and use IPNS to point to the latest version. Each mutation creates a new CID. This is essentially what OrbitDB does, but you can do it more simply for single-writer scenarios. + +**Verdict:** Good foundation for storing immutable snapshots of profile state. Not a KV store by itself. For UXF, the pattern would be: serialize profile to DAG-CBOR, store via Helia, publish CID via IPNS or a custom pointer. + +--- + +### 3. IPNS for Mutable Pointers + +**How it works:** An IPNS name is derived from a public key (ed25519 or secp256k1). The owner signs an IPNS record pointing `name -> /ipfs/CID`. Records are published to the Amino DHT or via PubSub. + +**Performance (ProbeLab measurements, 2025):** +- Median DHT publish latency: ~5-10 seconds +- Median DHT resolve latency: ~11 seconds +- P95 resolve latency: >30 seconds +- Success rate: High (correct record returned even under churn with quorum of 16) + +**IPNS over PubSub:** Much faster (sub-second for subscribed peers) but only works when both publisher and resolver are online and subscribed to the same topic. Falls back to DHT for cold resolution. + +**TTL:** Default suggested 5 minutes (300 billion nanoseconds). Can be tuned. Lower TTL = fresher data but more DHT queries. Higher TTL = better caching but stale data risk. + +**Verdict:** IPNS DHT resolution is too slow (~11s median) for wallet profile lookups in interactive contexts. Acceptable for background sync. For UXF, consider IPNS only as a fallback discovery mechanism, not as the primary lookup path. Use a faster resolution layer (like Nostr relay events, which the SDK already has) and IPNS as a backup. + +--- + +### 4. w3name / Storacha + +**w3name:** A hosted IPNS-like service by Storacha (formerly web3.storage). Creates self-certifying mutable names backed by ed25519 keypairs. Records are signed locally; the service just stores and serves them. No account or API key needed for basic use. + +**API:** +```typescript +import * as Name from 'w3name' +const name = await Name.create() // generates keypair +const revision = await Name.v0(name, '/ipfs/bafyabc...') +await Name.publish(revision, name.key) +// Later: +const latest = await Name.resolve(name) +``` + +**Performance:** w3name's hosted endpoint resolves much faster than DHT IPNS (sub-second for cached records). But it is a centralized service -- if Storacha goes down, resolution fails. + +**Storacha / w3up:** The broader storage platform. Upload CAR files, get CIDs, use UCAN-based authorization. Supports delegation (a space owner can grant upload rights to clients). Free tier available. Data stored on IPFS + Filecoin. + +**Verdict:** w3name is a pragmatic choice if you want fast mutable pointers without running DHT infrastructure. The centralization trade-off is acceptable for non-critical metadata (profile display name, avatar CID). For UXF, w3name could serve as the "fast path" for profile CID resolution, with DHT IPNS as backup. + +--- + +### 5. CAR Files as Local Cache + +**CARv1:** A streaming archive of IPLD blocks. Header contains root CIDs, followed by length-prefixed (CID, bytes) pairs. Sequential access only. + +**CARv2:** Wraps CARv1 with a fixed 40-byte header (characteristics bitfield, data offset/size, index offset/size) and an appended index. The index maps CID to byte offset in the CARv1 payload, enabling random access by CID. + +**Index types:** `IndexSorted` (sorted CID multihash digests + offsets), `MultihashIndexSorted`. Both support binary search for O(log n) lookups. + +**TypeScript implementation:** `@ipld/car` (v5.4.2, Apache-2.0/MIT). `CarReader` for streaming, `CarIndexedReader` for random-access reads after a full scan to build an in-memory index. Works in browsers (async iterables) but some raw-file operations are Node.js only. + +**As a local cache:** A CARv2 file is an excellent format for a local IPLD block cache: +- Content-addressed: blocks are deduplicated by CID +- Self-contained: no external dependencies +- Random access via index: fetch any block by CID in O(log n) +- Portable: can be synced, backed up, or transferred as a single file + +**Limitations:** +- CARv2 is append-friendly but not easily mutable (deleting blocks requires rewriting) +- The JS `CarIndexedReader` builds an in-memory index on open (scan cost proportional to file size) +- No built-in compaction; deleted/superseded blocks remain until archive is rebuilt +- Browser storage: must store the CAR bytes in IndexedDB or OPFS (see section 7) + +**Verdict:** CAR files are the recommended transport and cache format for UXF token pools. Use CARv2 for the on-disk/local representation. For small profiles (<1MB), the full-scan index cost is negligible. For larger token pools, consider pre-built indexes. + +--- + +### 6. Existing Patterns for Wallet/User State on IPFS + +**WNFS (WebNative File System):** +- Rust implementation compiled to WASM, actively developed (rs-wnfs, last updated Sep 2025) +- Two-layer encryption: private HAMT with XChaCha20-Poly1305, skip ratchets for temporal access control +- Versioned via content-addressing; each mutation produces a new root CID +- Conflict resolution: multivalue buckets in HAMT (all conflicting versions kept; app resolves) +- Designed for user-owned data; keys never leave the client +- **Applicable pattern for UXF:** The skip-ratchet key derivation (forward secrecy without backward access) is relevant for shared wallet profiles where you want to revoke past access. The HAMT structure for organizing private data by encrypted labels is elegant. + +**Ceramic Network / ComposeDB:** +- **Deprecated.** 3Box Labs merged with Textile in 2024. ComposeDB and js-ceramic are no longer maintained. +- ceramic-one (Rust) continues as infrastructure but the developer-facing SDK layer is gone. +- **Do not build on Ceramic for new projects.** + +**Textile (Threads/Buckets):** +- Original Textile Threads are deprecated. The company now focuses on Tableland (SQL on-chain) and Basin (data streaming). +- Not suitable for new IPFS-based storage projects. + +**State of the art (2025):** The space has consolidated. WNFS is the most sophisticated user-owned-data-on-IPFS system still actively developed. For simpler use cases, the pattern is: DAG-CBOR serialization -> CAR packaging -> upload to Storacha/pin service -> IPNS/w3name pointer. + +--- + +### 7.

It provides synchronous read/write without SharedArrayBuffer workarounds (since SQLite 3.43's opfs-sahpool VFS). +- IndexedDB is better for structured KV lookups (token metadata, profile fields). +- `navigator.storage.persist()` should always be called to prevent eviction of wallet data. +- Chromium grants persistent storage automatically to installed PWAs and sites with high engagement scores. + +**Recommendation for UXF:** +- **Profile KV data** (nametag, display name, settings): IndexedDB (already used by sphere-sdk) +- **CAR file cache** (token pool blocks): OPFS in a Web Worker for best performance, with IndexedDB fallback for older browsers +- **SQLite WASM + OPFS**: Overkill unless you need relational queries over token data + +--- + +### 8. Node.js Storage Options + +| Engine | Read perf | Write perf | ACID | Size | Notes | +|--------|-----------|------------|------|------|-------| +| **lmdb-js** | ~1.9M ops/sec single-thread | ~500K puts/sec | Yes (MVCC) | ~5MB native | Memory-mapped, crash-safe, zero-copy reads, V8 fast-api integration.

Best for complex queries. | +| **classic-level** (LevelDB) | Good | Good (LSM) | No | ~2MB native | Simple KV, sorted keys, range scans. Used by Helia internals. | + +**Recommendation for UXF Node.js:** +- **lmdb-js** is the best fit for a profile KV store. It is the fastest for the read-heavy pattern of wallet lookups, supports structured JS values natively (MessagePack encoding built in), is fully ACID, and handles concurrent access across threads/processes. No schema overhead. +- **better-sqlite3** if you ever need SQL queries or want to store the profile alongside relational data (transaction history, etc.). +- **classic-level** if you want minimal dependencies and are already in the Helia/IPFS ecosystem (it is what Helia uses internally). + +--- + +### 9. Sync Patterns + +**Recommended architecture for UXF profile sync:** + +1. **Single-writer model:** Each wallet identity owns its profile. Only the private key holder can update it. This eliminates multi-writer conflict resolution. + +2. **Optimistic local-first writes:** + - Mutate profile locally (IndexedDB/LMDB) + - Serialize to DAG-CBOR, package as CAR + - Upload CAR to IPFS (Storacha/pin service) + - Publish new CID via IPNS/w3name + - Background: no blocking on network + +3. **Pull-based sync (other devices / readers):** + - Resolve IPNS name -> get latest CID + - Fetch CAR from IPFS gateway/trustless gateway + - Verify blocks (content-addressed, self-authenticating) + - Merge into local cache (CID-based dedup: if block already present, skip) + +4. **Conflict resolution (multi-device same-owner):** + - Since IPNS records have sequence numbers, the highest sequence wins + - For concurrent edits from two devices: last-write-wins on the IPNS record level + - For finer granularity: embed a logical clock or vector clock in the profile DAG, merge field-by-field + - Simplest approach: treat the profile as a single atomic document; last publish wins + +5. **Versioning:** + - Each profile version is a distinct CID (immutable) + - Previous versions remain retrievable if pinned + - The IPNS record acts as a "HEAD pointer" to the latest version + +**Applicable CRDT patterns:** +- For simple KV profiles: LWW-Register per field (timestamp + value) is sufficient +- For token pools: OR-Set (observed-remove set) for token membership +- For append-only data (transaction history): G-Set (grow-only set) + +--- + +### 10. Lazy Loading from IPFS + +**Individual block fetching:** Yes, IPFS supports fetching individual IPLD blocks by CID. The trustless gateway spec supports `application/vnd.ipld.raw` (single block) and `application/vnd.ipld.car` (DAG as CAR). + +**Gateway pattern:** +``` +GET https://trustless-gateway.link/ipfs/{cid}?format=raw +``` +Returns the raw block bytes. The client verifies the CID matches the hash of the received bytes. + +**Latency (2025):** +- CDN-cached block: 50-200ms (via gateways like `trustless-gateway.link`, `dweb.link`) +- Uncached, DHT discovery required: 2-10 seconds (content routing + retrieval) +- Edge-cached via dedicated gateway: <100ms + +**@helia/verified-fetch:** A fetch()-like API for browsers that retrieves and verifies IPFS content from trustless gateways. Supports WebSocket and WebRTC Bitswap for direct provider retrieval, falls back to HTTP gateways. + +```typescript +import { verifiedFetch } from '@helia/verified-fetch' +const response = await verifiedFetch('ipfs://bafyabc...') +const data = await response.json() +``` + +**Partial CAR retrieval (IPIP-0402):** Trustless gateways can serve partial CARs for byte ranges or directory listings, reducing round trips. + +**Recommendation for UXF:** Design the profile DAG with lazy loading in mind: +- Root node contains metadata + CID links to sub-trees (tokens, history, settings) +- Fetch root first (small, fast) +- Fetch sub-trees on demand as the UI needs them +- Cache fetched blocks locally in a CARv2 file or IndexedDB blockstore +- Example structure: + ``` + root (DAG-CBOR, ~500 bytes) + ├── /meta -> CID (profile metadata: nametag, display name) + ├── /tokens -> CID (HAMT of token pool) + ├── /history -> CID (append-only log of transfers) + └── /certs -> CID (shared unicity certificates) + ``` +- Fetching `/meta` alone is one HTTP request (~200ms cached). The full token pool is only fetched when the payments view opens. + +--- + +## Concrete Recommendations for UXF Profile Design + +1. **Serialization:** Use DAG-CBOR for all profile data. It is IPLD-native, compact, and schema-evolvable. Avoid JSON-in-IPFS (wastes space, no IPLD linking). + +2. **Packaging:** CARv2 files as the canonical exchange format for UXF token pools. Include a block-level index for random access. Use `@ipld/car` for TypeScript read/write. + +3. **Mutable pointer:** Use w3name (Storacha) for fast profile CID resolution (sub-second). Publish to DHT IPNS as a fallback. The sphere-sdk's existing Nostr relay infrastructure can also serve as a resolution layer (publish `profile_cid` in a Nostr event, resolve via relay query -- fastest option, already deployed). + +4. **Browser storage:** IndexedDB for profile KV fields via `IndexedDBStorageProvider` (already in sphere-sdk). OPFS (Web Worker + SyncAccessHandle) for CAR file cache of the full token pool. Call `navigator.storage.persist()`. + +5. **Node.js storage:** lmdb-js for the profile KV store (fastest reads, ACID, native structured data). File system for CAR file cache. + +6. **Sync:** Single-writer, local-first. Write locally, serialize to DAG-CBOR + CAR, upload to Storacha (UCAN-authorized), update w3name pointer. Readers resolve pointer, fetch CAR, verify blocks, merge into local blockstore. + +7. **Lazy loading:** Structure the profile DAG as a shallow tree with CID links. Fetch root + metadata eagerly (<1KB). Fetch token pool, history, and certificates on demand. Use `@helia/verified-fetch` or direct trustless gateway HTTP calls. + +8. **Skip OrbitDB** unless multi-writer real-time collaboration is required. The CRDT OpLog adds significant complexity and bundle size for a single-writer wallet profile. + +9. **Skip Ceramic/Textile** -- both are deprecated/pivoted. + +10. **Consider WNFS patterns** (skip ratchets, encrypted HAMT) if profile encryption and temporal access control become requirements.

IPLD Data Model and Codecs + +### Core Data Model + +IPLD (InterPlanetary Linked Data) represents data as a DAG (Directed Acyclic Graph) of **blocks**. Each block is a tuple of `(CID, bytes)` where the CID is derived from the block's content. The IPLD Data Model defines these kinds: Null, Boolean, Integer, Float, String, Bytes, List, Map, and **Link** (a CID reference to another block). + +Links are the key primitive: a CID embedded in one block's data that references another block, forming edges in the DAG. + +### Available Codecs + +| Codec | Code | Format | Full Data Model | Best For | +|-------|------|--------|----------------|----------| +| **dag-cbor** | `0x71` | Binary (CBOR) | Yes | Structured data with links, binary payloads | +| **dag-json** | `0x0129` | JSON text | Yes | Human-readable debugging, APIs | +| **dag-pb** | `0x70` | Protobuf | Partial | UnixFS file chunking (legacy IPFS) | +| **raw** | `0x55` | Raw bytes | N/A | Opaque blobs, leaf data | + +### Recommendation for UXF + +**dag-cbor** is the clear choice for the UXF use case. Reasons: + +1. **Full Data Model support** -- supports all IPLD kinds including native CID links (encoded as CBOR Tag 42). +2. **Deterministic serialization** -- DAG-CBOR mandates canonical encoding (sorted map keys, no indefinite-length items, smallest integer encoding), which is essential for content-addressability. +3. **Efficient binary encoding** -- unlike dag-json, bytes are encoded natively (not base64-inflated). Token proofs, signatures, and hashes are predominantly binary data. +4. **Widely supported** -- it is the codec used by Filecoin for its entire chain state, by Ceramic Network for document streams, and by NFT.Storage for metadata bundles. + +dag-json is useful as a secondary codec for debugging and human inspection but should not be the primary storage format due to ~33% inflation on binary data from base64 encoding. + +### CID Versions + +**CIDv1** is recommended for all new projects. Structure: + +``` + +``` + +- **CIDv0**: Legacy, fixed to `dag-pb` + `sha2-256`, base58btc encoding. 34 bytes binary. Cannot represent dag-cbor content. +- **CIDv1**: Self-describing. Supports any codec + any hash. For dag-cbor + sha2-256, binary size is approximately 36 bytes (1 byte version + 1-2 bytes codec varint + 2 bytes multihash header + 32 bytes sha256 digest). + +**Multihash choice**: `sha2-256` is the standard default and recommended unless there is a specific reason to use alternatives like `blake2b-256` (slightly faster but less universal tooling support). + +### Deterministic Serialization in dag-cbor + +DAG-CBOR enforces strict canonical encoding per the spec: + +- **Map keys**: Must be strings only. Sorted by byte-wise comparison of their CBOR encoding (length-first, then lexicographic). +- **Integer encoding**: Smallest possible encoding. Positive integers use major type 0, negative use major type 1. +- **Float encoding**: IEEE 754 NaN, Infinity, -Infinity are forbidden. Floats that can be represented as integers must be encoded as integers. +- **No indefinite-length**: All strings, bytes, lists, and maps must use definite-length encoding. +- **Links**: CIDs are encoded as CBOR byte strings with Tag 42, using the raw-binary CID form with a `0x00` multibase prefix byte. + +**JavaScript pitfalls**: +- All JS `Number` values are 64-bit IEEE 754 floats internally. Integers outside the safe range (`Number.MAX_SAFE_INTEGER` = 2^53-1) lose precision. The `@ipld/dag-cbor` library handles this by using `BigInt` for integers outside the safe range on decode and accepting `BigInt` on encode. +- `Uint8Array` is the canonical bytes type. TypedArrays round-trip as `Uint8Array` (type information is lost). +- JavaScript `Map` key ordering is insertion-order, but dag-cbor sorts keys by CBOR byte order regardless of insertion order, so determinism is preserved. + +## 2. IPLD Schema and Advanced Data Structures + +### IPLD Schema Language + +IPLD Schemas define typed data structures over the IPLD Data Model. They provide: + +- **Structural types**: `struct`, `union`, `enum`, `list`, `map`, `link` +- **Representations**: How types map to the Data Model (e.g., `struct` can be represented as a `map` or `tuple`) +- **Typed links**: `&TargetType` syntax to indicate a CID link that should resolve to a specific type +- **Nullable and optional fields** + +Example schema for a UXF-like structure: + +```ipldsch +type Token struct { + genesis &Genesis + transactions [&Transaction] + state &TokenState + nametags [&Token] +} representation map + +type Genesis struct { + transactionData &MintTransactionData + inclusionProof &InclusionProof + destinationState &TokenState +} representation map +``` + +### Schema Validation in JavaScript + +- **`@ipld/schema`** (actively maintained) -- parser, validator, code generator for IPLD schemas. +- **`ipld-schema-validator`** -- builds runtime validator functions from IPLD schema definitions. Example: + +```javascript +import { parse as parseSchema } from 'ipld-schema' +import { create as createValidator } from 'ipld-schema-validator' + +const schema = parseSchema(schemaText) +const validate = createValidator(schema, 'Token') +validate(decodedBlock) // returns boolean +``` + +Note: The `ipld-schema-validator` library has been archived with functionality rolled into `@ipld/schema`. + +### Advanced Data Layouts (ADLs) + +ADLs are "lenses" that make sharded or transformed data appear as a single logical node: + +- **HAMT** (Hash Array Mapped Trie): Provides a map interface over sharded blocks. Deterministic (no hysteresis -- same content always produces same structure regardless of insertion order). Useful for very large element pools. +- **Prolly Trees**: Probabilistic B-trees for ordered indexes. Deterministic chunking based on content hashing. Used by Fireproof database. O(log_k(n)) read/write. Good for sorted indexes (e.g., token manifest sorted by tokenId). + +For UXF's element pool, if the pool grows very large (thousands of elements), a HAMT or Prolly Tree could shard the pool across multiple blocks while maintaining a single logical root CID. For moderate sizes (hundreds of elements), a single dag-cbor map block is simpler and sufficient. + +## 3. JavaScript/TypeScript Libraries + +### Core Libraries + +| Package | Version | Purpose | +|---------|---------|---------| +| `multiformats` | **13.4.2** | CID creation, multihash, multicodec, multibase | +| `@ipld/dag-cbor` | **9.2.5** | dag-cbor encode/decode with CID link support | +| `@ipld/dag-json` | **10.2.5** | dag-json encode/decode (human-readable) | +| `@ipld/car` | **5.4.2** | CAR file reading/writing (CARv1 focused) | +| `@ipld/schema` | latest | IPLD schema parsing and validation | +| `helia` | **6.0.14** | Modern IPFS node (ESM + TypeScript, successor to js-ipfs) | +| `cborg` | (dep of dag-cbor) | Low-level CBOR encoder/decoder with strictness | + +All packages are ESM-only and TypeScript-native. + +### API Examples + +**Creating a content-addressed block:** + +```typescript +import { encode, decode } from '@ipld/dag-cbor' +import { CID } from 'multiformats' +import { sha256 } from 'multiformats/hashes/sha2' + +// Encode a leaf node +const leafData = { type: 'authenticator', pubkey: new Uint8Array([...]), signature: new Uint8Array([...]) } +const leafBytes = encode(leafData) +const leafHash = await sha256.digest(leafBytes) +const leafCid = CID.createV1(0x71, leafHash) // 0x71 = dag-cbor codec + +// Encode a parent node with a CID link to the leaf +const parentData = { + type: 'inclusionProof', + authenticator: leafCid, // CID instances are encoded as IPLD links (Tag 42) + merkleTreePath: [new Uint8Array([...])], +} +const parentBytes = encode(parentData) +const parentHash = await sha256.digest(parentBytes) +const parentCid = CID.createV1(0x71, parentHash) + +// Decode +const decoded = decode(parentBytes) +CID.asCID(decoded.authenticator) // returns CID instance +``` + +**Encoding options for size calculation:** + +```typescript +import { encodeOptions } from '@ipld/dag-cbor' +import { encodedLength } from 'cborg/length' +const byteLength = encodedLength(data, encodeOptions) +``` + +### Helia (Modern IPFS) + +Helia is the official successor to js-ipfs, designed as composable and modular: + +```typescript +import { createHelia } from 'helia' +import { dagCbor } from '@helia/dag-cbor' + +const helia = await createHelia() +const d = dagCbor(helia) +const cid = await d.add({ hello: 'world' }) +const obj = await d.get(cid) +``` + +For UXF, Helia is relevant if the package needs to interact with the live IPFS network (pinning, retrieval). For offline packaging (creating CAR files for later upload), the lower-level `@ipld/dag-cbor` + `@ipld/car` combination is sufficient and has zero network dependencies. + +## 4. CAR Files (Content Addressable aRchive) + +### Overview + +CAR is the transport/archive format for IPLD blocks. A CAR file is essentially exactly what UXF needs: **a bundle of content-addressed blocks with a root pointer**. The mapping is direct: + +| UXF Concept | CAR Equivalent | +|-------------|---------------| +| Element Pool | Collection of IPLD blocks in the CAR body | +| Token Manifest root | CAR root CID(s) | +| Element hash | Block CID | +| Child references | CID links within dag-cbor encoded blocks | + +### CARv1 Format + +Structure: + +``` +[header: dag-cbor encoded {version: 1, roots: [CID...]}] +[block: varint(len) + CID + bytes] +[block: varint(len) + CID + bytes] +... +``` + +- **Header**: dag-cbor encoded map with `version: 1` and `roots: [CID]` array listing root block CIDs. +- **Body**: Sequence of length-prefixed blocks, each containing the block's CID followed by its raw bytes. +- **Streaming**: Blocks can be written and read sequentially -- no random access required. This satisfies UXF's streaming-friendly constraint. +- **Multiple roots**: A CAR can have multiple roots (e.g., one per token, or a single manifest root). + +### CARv2 Format + +CARv2 wraps a CARv1 payload with additional metadata: + +``` +[CARv2 pragma: 11 bytes identifying CARv2] +[CARv2 header: 40 bytes fixed] + - Characteristics: 128-bit bitfield + - Data offset: uint64 (byte offset to inner CARv1) + - Data size: uint64 (byte length of inner CARv1) + - Index offset: uint64 (byte offset to index) +[CARv1 payload] +[Index: CID -> offset mapping] +``` + +Key CARv2 features: +- **Index for random access**: Maps CID to byte offset within the CARv1 payload, enabling O(1) block lookup without sequential scanning. +- **Characteristics bitfield**: Extensible flags describing the archive. +- **Backward compatible**: The inner payload is a valid CARv1. + +### JavaScript CAR API + +```typescript +import { CarWriter } from '@ipld/car/writer' +import { CarReader } from '@ipld/car' + +// Writing +const { writer, out } = CarWriter.create([rootCid]) + +// Pipe output to file or buffer +const chunks: Uint8Array[] = [] +const collectPromise = (async () => { + for await (const chunk of out) chunks.push(chunk) +})() + +// Add blocks +await writer.put({ cid: leafCid, bytes: leafBytes }) +await writer.put({ cid: parentCid, bytes: parentBytes }) +await writer.put({ cid: rootCid, bytes: rootBytes }) +await writer.close() +await collectPromise + +const carBytes = concat(chunks) // single Uint8Array + +// Reading +const reader = await CarReader.fromBytes(carBytes) +const roots = await reader.getRoots() +const block = await reader.get(someCid) // { cid, bytes } + +// Iterate all blocks +for await (const { cid, bytes } of reader.blocks()) { + // process each block +} +``` + +**`CarIndexedReader`** provides random-access reading from a file descriptor using an index, useful for large archives. + +### CAR as UXF Transport Format + +The alignment between CAR and UXF is remarkably tight: + +1. **UXF Bundle = CAR file**. The element pool maps to the collection of blocks. The manifest is a dag-cbor block whose CID is listed as a CAR root. +2. **Deduplication**: Each block appears once in the CAR by CID. Shared sub-DAGs (unicity certificates, nametag tokens) are stored as single blocks referenced by multiple parents. +3. **Streaming creation**: `CarWriter` supports streaming -- blocks can be added as they are deconstructed from tokens, without buffering the entire pool in memory. +4. **Streaming consumption**: `CarReader` supports iteration -- tokens can begin reassembly as blocks arrive. +5. **IPFS upload**: CAR files can be uploaded directly to Storacha (web3.storage successor), Filecoin, or any IPFS pinning service that accepts CAR uploads. +6. **Indexes**: For the UXF token manifest and secondary indexes (by tokenType, by state hash), these are simply additional dag-cbor blocks in the CAR with their CIDs tracked as roots or linked from the manifest. + +## 5. Packaging Patterns for Complex Hierarchical Data + +### Pattern: NFT.Storage dag-cbor Bundle + +NFT.Storage creates a dag-cbor "bundle" that includes structured metadata with native IPLD links to all referenced files. This is the closest existing pattern to what UXF needs: + +- A root dag-cbor block contains the metadata structure +- Binary assets are stored as raw blocks +- CID links connect them into a DAG +- The entire bundle is packaged as a CAR file + +### Pattern: Filecoin Chain State + +Filecoin is "probably the most sophisticated example of DAG-CBOR IPLD blocks used to represent a very large and scalable graph of structured data." The entire Filecoin chain state is an IPLD DAG using dag-cbor blocks with HAMT sharding for large collections. + +### Pattern: Ceramic Network Document Streams + +Ceramic uses IPLD for hash-linked event logs (document streams): + +- Each event is an IPLD block (dag-cbor or dag-jose for signed/encrypted) +- Events link to predecessors via CID +- Streams have an immutable `streamId` derived from the genesis event's CID +- ComposeDB adds a GraphQL layer on top + +This is relevant to UXF's instance chains (newer instances linking to predecessors via content hash). + +### Pattern: WNFS (Web Native File System) + +WNFS by Fission builds a complete filesystem on IPLD: + +- Public and private branches +- Versioned with CRDT semantics for concurrent writes +- Serializes/deserializes from IPLD graphs +- Uses "virtual nodes": Raw IPLD nodes, File nodes (data + metadata), Directory nodes (index + metadata) +- Rust implementation (`rs-wnfs`) with WASM bindings + +### Pattern: Fireproof Database + +Fireproof uses IPLD prolly trees for a content-addressable database: + +- Documents stored in prolly-tree indexes (deterministic B-tree variant) +- Updates logged to a Merkle clock (causal event log) +- All data packaged as CAR files +- Same data always produces same physical layout and Merkle root + +### Pattern: Storacha/w3up + +The successor to web3.storage uses a CAR-centric upload pipeline: + +- Client-side: files are chunked and hashed to calculate root CID locally +- Packaged as CAR files +- Uploaded with UCAN authorization +- Index created for retrieval + +### UnixFS vs Raw IPLD DAGs + +For UXF, **raw IPLD DAGs with dag-cbor** are the correct choice, not UnixFS: + +- UnixFS is designed for file/directory hierarchies with chunked byte streams +- UXF's data is structured (maps, lists, typed fields, CID links) -- not files +- dag-cbor supports the full IPLD Data Model; dag-pb (used by UnixFS) does not +- Filecoin's entire chain state validates this approach at massive scale + +### IPNS for Mutable Package Roots + +IPNS provides stable names for mutable content: + +- Each IPNS name is derived from a keypair +- Resolves to a CID that can be updated by the key holder +- IPNS records contain: content path, expiration, version/sequence number, cryptographic signature + +For UXF, IPNS is relevant for the "latest version of my token pool" use case: as tokens are added/removed, the manifest root CID changes, but the IPNS name remains stable. The existing sphere-sdk already uses IPNS for wallet state publishing (`impl/shared/ipfs/`). + +## 6. Deterministic Serialization Deep Dive + +### dag-cbor Guarantees + +dag-cbor provides the strongest determinism guarantees of any IPLD codec: + +1. **Map key ordering**: Keys sorted by CBOR-encoded byte comparison (length-prefix first, then lexicographic). This is NOT JavaScript string comparison -- it is comparison of the raw CBOR-encoded key bytes. +2. **Integer minimality**: Must use smallest possible CBOR encoding. +3. **No duplicate map keys**: Strictly forbidden. +4. **No indefinite-length**: All containers must be definite-length. +5. **Float canonicalization**: Must use smallest IEEE 754 encoding (half, single, double) that preserves the value. NaN/Infinity forbidden. +6. **Tag 42 only**: No CBOR tags except 42 (CID links). All other tags are rejected. + +### Ensuring Identical CIDs + +To guarantee identical content produces identical CIDs: + +1. **Always use `@ipld/dag-cbor` encode/decode** -- it enforces all canonicalization rules. Never hand-craft CBOR. +2. **Normalize data before encoding**: Ensure no `undefined` values (not representable in CBOR), no `NaN`/`Infinity`, no non-string map keys. +3. **Use `Uint8Array` for all binary data** -- not `Buffer` or other typed arrays. +4. **CID links must be `CID` instances** -- the encoder recognizes them via `CID.asCID()` and applies Tag 42. +5. **Avoid JavaScript `Number` for large integers** -- use `BigInt` for values outside safe integer range. + +### Known Pitfalls + +- **Object property order in JavaScript**: `@ipld/dag-cbor` sorts keys during encoding, so JS object property insertion order does not affect the output. This is safe. +- **`undefined` vs `null`**: `undefined` is not representable in CBOR. Omit fields rather than setting them to `undefined`. +- **`Buffer` vs `Uint8Array`**: Node.js `Buffer` extends `Uint8Array` and will encode correctly, but round-trips as `Uint8Array`. +- **Floating point precision**: `0.1 + 0.2` !== `0.3` in JavaScript. Avoid floats for values that must be deterministic. Use integers or string representations for amounts. + +## 7. Performance and Size Considerations + +### Block Size + +- **IPFS recommended max**: 1 MiB per block (for network compatibility). +- **Practical optimum**: 1-5 MB for transfer performance, but most structured data blocks are far smaller. +- **For UXF**: Individual token elements (transactions, proofs, certificates) are typically 200 bytes to 5 KB each.

Use `dag-json` only for debugging/inspection tools. + +2. **CIDs**: Use CIDv1 with `sha2-256` via `multiformats` v13.4.2. Binary CIDs are ~36 bytes. + +3. **Archive format**: Use **CAR files** (`@ipld/car` v5.4.2) as the UXF bundle container. A UXF bundle IS a CAR file -- the element pool maps to blocks, the manifest root is the CAR root. CARv1 is sufficient for most use cases; CARv2 adds indexing for large archives. + +4. **Block granularity**: Decompose at the level where deduplication provides measurable benefit -- shared sub-elements (certificates, nametag tokens, SMT segments) as separate blocks; unique leaf data inlined into parent blocks. + +5. **Schema validation**: Use `@ipld/schema` for defining and validating element types. + +6. **Determinism**: Rely on `@ipld/dag-cbor`'s canonical encoding. Avoid floats for deterministic values. Use `BigInt` for large integers. Always use `Uint8Array` for binary data. + +7. **Streaming**: `CarWriter`/`CarReader` support streaming creation and consumption, satisfying the streaming-friendly constraint. + +8. **IPFS integration**: CAR files can be uploaded directly to Storacha/web3.storage, IPFS pinning services, or used with Helia for peer-to-peer distribution. The existing sphere-sdk IPNS infrastructure can point to the latest CAR root. + +9. **Large pools**: If the element pool exceeds ~10K elements, consider HAMT sharding (as Filecoin does) to avoid single massive manifest blocks. + +10. **Instance chains**: Model after Ceramic's event stream pattern -- each new instance is a dag-cbor block with a `predecessor` CID link to the previous instance. + +--- + +Sources: +- [IPLD DAG-CBOR Specification](https://ipld.io/specs/codecs/dag-cbor/spec/) +- [IPLD DAG-JSON Specification](https://ipld.io/specs/codecs/dag-json/spec/) +- [IPLD Codec Docs: DAG-CBOR](https://ipld.io/docs/codecs/known/dag-cbor/) +- [IPLD Codec Docs: DAG-JSON](https://ipld.io/docs/codecs/known/dag-json/) +- [IPLD Specs Repository](https://github.com/ipld/specs) +- [@ipld/dag-cbor on npm](https://www.npmjs.com/package/@ipld/dag-cbor) +- [@ipld/dag-json on npm](https://www.npmjs.com/package/@ipld/dag-json) +- [@ipld/car on npm](https://www.npmjs.com/package/@ipld/car) +- [multiformats on npm](https://www.npmjs.com/package/multiformats) +- [@ipld/schema on npm](https://www.npmjs.com/package/@ipld/schema) +- [js-dag-cbor GitHub](https://github.com/ipld/js-dag-cbor) +- [js-car GitHub](https://github.com/ipld/js-car) +- [CARv1 Specification](https://ipld.io/specs/transport/car/carv1/) +- [CARv2 Specification](https://ipld.io/specs/transport/car/carv2/) +- [IPLD Advanced Data Layouts](https://ipld.io/docs/advanced-data-layouts/) +- [IPLD HAMT Specification](https://ipld.io/specs/advanced-data-layouts/hamt/spec/) +- [IPLD Prolly Tree Proposal](https://github.com/ipld/ipld/pull/254) +- [Prolly Tree Analysis](https://blog.mauve.moe/posts/prolly-tree-analysis) +- [Content Identifiers (CIDs) - IPFS Docs](https://docs.ipfs.tech/concepts/content-addressing/) +- [Multiformats CID Spec](https://github.com/multiformats/cid) +- [Helia - Modern IPFS in TypeScript](https://github.com/ipfs/helia) +- [Helia on npm](https://www.npmjs.com/package/helia) +- [ipld-schema-validator on npm](https://www.npmjs.com/package/ipld-schema-validator) +- [Ceramic Network - How it Works](https://ceramic.network/how-it-works) +- [Ceramic Event Log Specification](https://developers.ceramic.network/protocol/streams/event-log/) +- [WNFS - Fission](https://fission.codes/ecosystem/wnfs/) +- [rs-wnfs GitHub](https://github.com/wnfs-wg/rs-wnfs) +- [Fireproof Architecture](https://use-fireproof.com/docs/architecture/) +- [Fireproof Database Engine](https://fireproof.storage/documentation/how-the-database-engine-works/) +- [Storacha CAR Documentation](https://docs.storacha.network/concepts/car/) +- [DASL - Data-Addressed Structures & Links](https://dasl.ing/) +- [DASL CAR Specification](https://dasl.ing/car.html) +- [IPFS IPLD Block Size Discussion](https://discuss.ipfs.tech/t/supporting-large-ipld-blocks/15093) +- [NFT.Storage CAR Files](https://dev.nft.storage/docs/concepts/car-files/) +- [Storacha/w3up Protocol](https://github.com/storacha/w3up) +- [IPNS Documentation](https://docs.ipfs.tech/concepts/ipns/) +- [cborg - CBOR Library](https://github.com/rvagg/cborg) \ No newline at end of file diff --git a/docs/uxf/ISSUE-455-INVESTIGATION.md b/docs/uxf/ISSUE-455-INVESTIGATION.md new file mode 100644 index 00000000..74abe7d4 --- /dev/null +++ b/docs/uxf/ISSUE-455-INVESTIGATION.md @@ -0,0 +1,182 @@ +# sphere-sdk #455 — Single-coin faucet flakiness investigation + +**Status:** Investigation closed — root cause identified (high confidence). +**Branch:** `investigate/issue-455-faucet-flakiness` +**Related:** sphere-sdk#444, PR #453 (cross-device durability split), sphere-cli PR #45 (operational workaround). + +## Symptom + +`manual-test-swap-roundtrip.sh` fails consistently at Section 2 (faucet + sync): + +``` +sphere faucet 100 UCT # → "✓ Received 100 unicity" +sphere payments sync # → [Nostr] [AT-LEAST-ONCE] TOKEN_TRANSFER … not durable + # — leaving 'since' at 0;

Bulk and single-coin paths use identical synchronization. There is no in-server publish race that could make the single-coin path race the receiver's subscription window. + +### H2 — Asymmetric payload encoding (V6 COMBINED_TRANSFER vs V5) + +**Status: REFUTED.** The faucet's `transferToProxyAddress` → `serializeToken` / `serializeTransaction` shape is the same per-request regardless of bulk/single (see `FaucetService.java:234-241`). The receiver's discrimination in `PaymentsModule.handleIncomingTransfer` (`modules/payments/PaymentsModule.ts:16329-16469`) covers all four legacy shapes via the same dispatch; the Sphere-wallet `{sourceToken, transferTx}` shape (which is what the faucet emits) routes identically in both cases. There is no V6 vs V5 split between bulk and single-coin requests. + +### H3 — Empty-handler buffer race on outer NostrTransportProvider + +**Status: CONFIRMED as a contributing factor for the warn line; partial root cause.** + +Reading the flow with MUX active (the default Sphere config): + +1. `Sphere.fetchPendingEvents()` (`core/Sphere.ts:2773`) calls `this._transport.fetchPendingEvents()`. `this._transport` is **always the OUTER `NostrTransportProvider`** — `_transport` is never reassigned to the mux/adapter (`core/Sphere.ts:940` is the only write). +2. Outer's `fetchPendingEvents` (`transport/NostrTransportProvider.ts:2724`) does NOT check `_subscriptionsSuppressed`. It unconditionally opens a one-shot subscription and dispatches every collected event through outer's `handleEvent` (`transport/NostrTransportProvider.ts:2814`). +3. The event reaches outer's `handleTokenTransfer` (`transport/NostrTransportProvider.ts:2304`). In MUX mode, **PaymentsModule registered its handler on the address ADAPTER, not on the outer** (`modules/payments/PaymentsModule.ts:2074` uses `deps.transport.onTokenTransfer`, and `deps.transport` is the adapter — `core/Sphere.ts:3851`). +4. Outer's `transferHandlers.size === 0` → event is pushed to `pendingTransfers` buffer (`transport/NostrTransportProvider.ts:2369-2376`) → **`return false`**. +5. Back in `handleEvent`, `recordDurabilityMiss(event.id)` arms the cooldown ledger and emits the exact warn line from the issue body: `[AT-LEAST-ONCE] TOKEN_TRANSFER … not durable — leaving 'since' at 0; cooldown 30000ms (attempt 1/3)`. + +This is the source of the warn line. **It is a benign side effect on the outer subscriber** — the actual receive of the token happens later via `payments.receive()` → mux adapter's `fetchPendingEvents` → `mux.fetchPendingEvents()` → `mux.handleEvent` → `entry.adapter.dispatchTokenTransfer` → PaymentsModule's handler. + +However, H3 in isolation does NOT explain the missing token. The mux's `dispatchTokenTransfer` (`transport/MultiAddressTransportMux.ts:2286-2298`) fires the handler. The token addToken should run. + +### H3-Extension (NEW finding) — Mux dispatch is fire-and-forget + +This was uncovered in the H3 trace and is the **most likely structural root cause of the missing-token symptom** (not the warn line). + +In `MultiAddressTransportMux.handleEvent → handleTokenTransfer → adapter.dispatchTokenTransfer`: + +```typescript +// transport/MultiAddressTransportMux.ts:2296-2298 +for (const handler of this.transferHandlers) { + try { handler(transfer); } catch (e) { logger.debug('MuxAdapter', 'Transfer handler error:', e); } +} +``` + +The handler is `PaymentsModule.handleIncomingTransfer` — an **async** function. `handler(transfer)` returns a Promise; the loop body does NOT `await` it. The mux's `handleTokenTransfer` returns immediately after dispatching; `fetchPendingEvents` then iterates the next event; `payments.receive()`'s `await this.deps!.transport.fetchPendingEvents()` resolves while the handlers are still in flight. + +Compare with `NostrTransportProvider.handleTokenTransfer` (`transport/NostrTransportProvider.ts:2380-2389`) which does `await handler(transfer)` and aggregates the durability signal — the correct contract. + +**Impact:** `payments.receive()`'s subsequent `await this.load()` (`modules/payments/PaymentsModule.ts:8192`) may read storage before any handler has finished writing. With 7 bulk events, the time budget per-event averages out and some handlers complete in time. With 1 single-coin event, the race is binary — either the handler beats `load()` or it doesn't. + +This explains the bulk-vs-single asymmetry: bulk wins by sheer luck (more chances for SOMETHING to complete in time); single is a clean coin-flip every run. + +### H4 — Relay event retention + +**Status: REFUTED on the available evidence.** Two independent reasons: + +1. `fetchPendingEvents` filters use `since = now - 86400 - 172800` (outer: `NostrTransportProvider.ts:2757`; mux: `MultiAddressTransportMux.ts:758`) — a 3-day lookback. Even an aggressive relay-side TTL would have to drop events within seconds for this to fire, which contradicts the steady operation of every other soak. +2. The issue's own log line shows the event ID makes it to the receiver (`TOKEN_TRANSFER ae59acc8f979 not durable`) — meaning the relay DID deliver the event. Retention can't be the cause when the event reaches the receiver's transport layer. + +The H4 hypothesis appears to have been a misdirection from the warn message's wording ("leaving 'since' at …") — the cursor is left pinned because the durability gate fired, not because the relay dropped anything. + +## Root cause (high confidence) + +The dominant root cause of the single-coin faucet flakiness is **H3-Extension: `MuxAdapter.dispatchTokenTransfer` is fire-and-forget**, breaking the await chain between `payments.receive()`'s `fetchPendingEvents` and the receive handler's completion. The auxiliary H3 (outer's empty-handler buffer) produces the cosmetic `[AT-LEAST-ONCE] not durable` warn line but does not by itself cause token loss. + +Why bulk masked this for ~2 years: + +- Bulk fan-out (`Promise.all` over 7 coins) produced 7 separate Nostr events with staggered arrival. +- The mux's fire-and-forget dispatch runs all 7 handler Promises in parallel. +- Even if one handler races `load()`, the next round of `payments.receive()` (called from `balance`, `tokens`, `history`, etc., each of which does its own `ensureSync`) gets another shot. +- With multiple events in flight, the wall-clock load() landing is statistically more likely to capture AT LEAST ONE token write — and the soaks' assertions usually only check "did SOMETHING land", not "did EXACTLY ONE specific coin land". +- Single-coin requests fail in a binary way: the one Promise wins or loses against load(). + +## Why sphere-cli PR #45 (local mint) closes the issue procedurally + +PR #45 replaced the HTTP-faucet path with `sphere.payments.mintFungibleToken()` — a synchronous, in-process L3 aggregator mint that returns AFTER addToken has run. No Nostr round trip, no mux dispatch race. The fix is correct as an operational workaround but does not address the underlying SDK defect. + +## Suggested next steps (in priority order) + +### 1. Fix `MuxAdapter.dispatchTokenTransfer` to await + collect durability + +Change `transport/MultiAddressTransportMux.ts:2286-2299` to await the handler Promise and propagate its boolean return value back through the mux's `handleEvent` chain so the `since` cursor advance honours the existing at-least-once invariant. Concretely: + +```typescript +// transport/MultiAddressTransportMux.ts +async dispatchTokenTransfer(transfer: IncomingTokenTransfer): Promise { + if (this.transferHandlers.size === 0) { + this.pendingTransfers.push(transfer); + return false; // not durable — replay on next reconnect + } + let allDurable = true; + for (const handler of this.transferHandlers) { + try { + const result = await handler(transfer); + if (result === false) allDurable = false; + } catch (e) { + logger.debug('MuxAdapter', 'Transfer handler error:', e); + allDurable = false; + } + } + return allDurable; +} +``` + +Then `MultiAddressTransportMux.handleTokenTransfer` (`MultiAddressTransportMux.ts:1331`) must await the new boolean and gate `updateLastEventTimestamp` accordingly — same pattern as `NostrTransportProvider.handleEvent` does for outer events. + +This is a structural fix; it eliminates the bulk-vs-single asymmetry entirely and also makes `sphere payments sync` deterministic for ANY single inbound event (faucet, P2P send, swap deposit, etc.). + +### 2. Suppress the outer's `fetchPendingEvents` when mux is active + +Check `_subscriptionsSuppressed` at the top of `NostrTransportProvider.fetchPendingEvents` (`transport/NostrTransportProvider.ts:2724`) and short-circuit when mux owns dispatch. This eliminates the spurious `[AT-LEAST-ONCE] not durable` warn storm and prevents the outer's cooldown ledger from being polluted with event IDs it can't actually process. + +The current code unconditionally subscribes; the implicit assumption that "outer handlers will eventually drain" is false in steady-state mux mode (the outer's handler set stays empty forever). + +### 3. Add a unit test that exercises the mux dispatch race + +A test that registers a slow async handler on the mux adapter, fires a single TOKEN_TRANSFER, and asserts that `mux.fetchPendingEvents()` returns ONLY AFTER the handler resolved would lock in the fix from step 1. + +### 4.

Both self-skip when no writer is installed, so the auto-install + auto-start is safe. +- The default `retentionMs` is 30 days. Don't change it as part of the flip — that's a separate consideration. + +**Test plan**: `npx vitest run tests/unit/payments/transfer/ tests/integration/payments/` should pass unchanged. + +### PR-2: flip `features.nostrPersistenceVerifier` default-ON + +**Files**: same shape as PR-1 but for the `nostrPersistenceVerifier` row. + +**Acceptance criteria**: same shape. + +**Gotchas**: +- Adds relay query traffic proportional to eligible SENT volume. Operators with restrictive relay sets should still be able to opt-out via explicit `false`. +- The verifier's `'missing'` outcome triggers Item #2's re-publish path. After Item #6.a lands, that path becomes more reliable — consider ordering Item #6.a BEFORE this PR for cleaner cross-flag behavior. + +**Adversarial review checklist** (for both PRs): +- Tests creating `PaymentsModule` without explicit feature flags — verify nothing breaks. +- Soak-gate semantics: original gate was about transient-failure false-positives; argue that the per-token throw-back-off (tombstone GC) or LRU cache (verifier) bounds the false-positive surface. + +--- + +# Item 6.a — IPFS-pin-only at send time + +**Current state**: `modules/payments/transfer/delivery-resolver.ts:resolveDelivery` only calls `publishToIpfs` on the CID branches. The `'inline'` branches (lines ~107-119 in the resolver outcome shape) return `{ kind: 'inline', carBase64 }` without a pin. Entries delivered inline have NO local IPFS pin, so the default `republish` closure in `PaymentsModule` throws `CAR_MODE_REPUBLISH_NOT_YET_SUPPORTED` and routes the entry to `'failed-transient'` via the recovery worker's retry exhaust. + +**Why it matters**: closes the residual gap in Item #2. After Item #6.a lands, the SENT entry's `bundleCid` is reliably fetchable regardless of original wire delivery mode, the default `republish` closure can downgrade `'car-over-nostr'` re-publishes to `'cid-over-nostr'` unconditionally, and the throw becomes the documented defensive fallback for the rare "pin TTL expired AND bundle bytes also gone from local storage" case. + +**Scope**: extend the resolver so the `'inline'` branches ALSO call `publishToIpfs` (or an equivalent local-pin function) for the same content-addressed CAR bytes. Pin is best-effort — a pin failure must NOT prevent the inline-CAR send from succeeding. The wire delivery mode stays inline; the pin is in addition. + +**Files**: +- `modules/payments/transfer/delivery-resolver.ts` — primary implementation. Inspect `resolveDelivery` and the `kind: 'inline'` return shape. Add a `shouldPin: true` field or a parallel pin invocation. The pin is fire-and-forget for the inline path. +- `modules/payments/PaymentsModule.ts:~1715-1740` (the default `republish` closure) — after this lands, downgrade `'car-over-nostr'` re-publishes to CID-shape unconditionally. The CAR-mode throw becomes the defensive fallback the original Item #6 doc anticipated. +- New tests: `tests/unit/payments/transfer/delivery-resolver-pin.test.ts` — assert the pin call happens on every inline branch. + +**Acceptance criteria** (from `OUTBOX-SEND-FOLLOWUPS.md` Item #6): +- Every successful send (any delivery mode) leaves a live IPFS pin on the sender's local node for `bundleCid`. +- CAR-mode re-publish closure downgrades to CID-over-Nostr. +- The CAR-mode throw becomes unreachable in the common case (only reached when the pin TTL has expired AND the bundle bytes are also gone from local storage). + +**Test plan**: +- Unit: inline branches call `publishToIpfs` exactly once per send; pin failure does NOT abort the send (warn-log only). +- Integration: a send delivered inline produces a fetchable CID afterwards (mock the IPFS gateway). +- Regression: every existing delivery-resolver test continues to pass. + +**Gotchas**: +- The "inline" path is for small bundles below `RELAY_SAFE_CAP_BYTES`. The pin cost is amortized across the send pipeline, so the change is incremental — not a new architectural concern. +- The `publishToIpfs` callback may not be wired in test fixtures. Defense-in-depth: if the callback is absent, skip the pin (don't throw) — same pattern as the `'force-cid'` over-cap "no publisher" arc that ALREADY falls back to inline. +- Backward compat: existing inline-CAR sends pre-flip are NOT retroactively pinned. The Item #2 re-publish closure should still throw the documented defensive error for those entries (entries created BEFORE this change has the deliveryMethod recorded as `'car-over-nostr'` AND no local pin). Date-based filtering or a synthetic `pinAvailableSince` marker on SENT entries could distinguish; OR just leave the defensive throw as the operator-triage path for legacy entries. + +**Adversarial review checklist**: +- Does the pin call block the send pipeline? Pin must be parallel / fire-and-forget. +- What happens if the pin fails AND the send succeeds? The CID is on the wire but not pinned locally — same as today's CID-over-Nostr force-cid path; verify the worker's republish can still re-pin on demand. +- Hex/CID encoding parity between the inline path and the existing CID path — verify `bundleCid` produced by both paths is byte-identical. + +--- + +# Item 2 — Auto-republish of retention drops (final closure) + +**Current state**: most of Item #2 is functional. The `NostrPersistenceVerifier` worker detects retention drops and emits `transfer:retention-warning`. The `SendingRecoveryWorker` re-publishes via the OUTBOX `delivered → sending` transition. Item #15's snapshot sync eliminated most cross-device skip cases. The cross-device test (`tests/integration/profile/retention-republish-after-snapshot-join.test.ts`, 3 tests) locks the behavior. + +The remaining gap is the inline-CAR retention case (covered by Item #6.a above). + +**Final closure work** (after Item #6.a lands): +1. Downgrade the default `republish` closure in `PaymentsModule` (`modules/payments/PaymentsModule.ts:~1715-1740`) to ALWAYS produce a `'cid-over-nostr'` re-publish, even for entries whose original `deliveryMethod` was `'car-over-nostr'`. +2. The pin from Item #6.a guarantees the CID is fetchable. +3. The CAR-mode throw becomes the documented defensive fallback for legacy entries (pre-#6.a) and the truly-degenerate "pin TTL expired" case. +4. Update `OUTBOX-SEND-FOLLOWUPS.md` Item #2 with a "Status (YYYY-MM-DD): SHIPPED" banner once both #6.a and this closure land. + +**Files**: +- `modules/payments/PaymentsModule.ts:~1715-1740` — the default `republish` closure. Today it has a `deliveryMethod` branch that throws for `'car-over-nostr'`. After Item #6.a, route both `'car-over-nostr'` and `'cid-over-nostr'` through the CID-shape re-publish. +- `docs/uxf/RUNBOOK-SEND-PIPELINE.md` `transfer:retention-republish-skipped` operator section — update the `'entry-tombstoned-or-missing'` paragraph and the `'transition-failed'` paragraph to reflect that the CAR-mode throw is now rare. +- `docs/uxf/OUTBOX-SEND-FOLLOWUPS.md` Item #2 status banner. + +**Test plan**: +- New unit test: `republish` closure for a `deliveryMethod='car-over-nostr'` entry produces a CID-shape payload (no throw) when the pin is available. +- Regression: the existing legacy-entry throw is preserved when the pin is NOT available. + +**Gotcha**: this PR is sequenced after Item #6.a.

Conservative + instant paths both capture the eventId now (Issue #166 P2 #3). +6. **Delivered transition** — OUTBOX entry → `'delivered'` (conservative) / `'delivered-instant'` (instant). The eventId is persisted onto the OUTBOX entry. +7. **SENT-ledger write** (`PaymentsModule.writeSentEntryFromOutbox`) — copies the OUTBOX entry into the SENT ledger (the permanent record). `nostrEventId` propagates from OUTBOX to SENT. +8. **OUTBOX tombstone** — on SENT-write success the OUTBOX entry is tombstoned (Lamport-stamped per Issue #166 P1 #2). On SENT-write failure the OUTBOX entry is **kept live at `'delivered'` for forensic record** (round-2 steelman fix in `fcf1d53`). +9. **Reconciliation** (`SentReconciliationWorker`, Issue #166 P2 #4, default-ON) — retries SENT writes for delivered-but-unreconciled entries. +10. **Recovery** (`SendingRecoveryWorker`, default-ON) — re-publishes entries stuck in `'sending'`. +11. **Retention verification** (`NostrPersistenceVerifier`, Issue #166 P2 #3, default-OFF) — re-queries the relay for retained events; emits `transfer:retention-warning` on detected drops. +12. **Orphan detection** (`PaymentsModule.detectOrphanSpendingTokens` → `sweepOrphanSpendingTokens`, Issue #166 P2 #1) — finds tokens stuck `'transferring'` with no matching OUTBOX/SENT entry; optionally auto-recovers (default-OFF). + +The OUTBOX is a working queue that **drains** to SENT as deliveries complete. Tombstones (NOT `db.del()`) are the drain mechanism — they survive CRDT merge against concurrent writes. + +--- + +## What landed in Issue #166 (for reference) + +| Bucket | Item | PR | Merge | +|--------|------|----|-------| +| P3 + P4 | 8 test-coverage gaps + 4 defensive hardening | #167 | `d109ff8` | +| P2 #4 | SENT-write reconciliation worker | #168 | `2f379c5` | +| P2 #2 | Duplicate-bundle guard | #169 | `c612c5c` | +| P2 #3 | Nostr persistence verification | #170 | `2072f06` | +| P2 #1 | Orphan-spending auto-recovery hook | #171 | `96af490` | +| P1 #2 + #3 | Tombstone Lamport + DoS bounds | #172 | `9051159` | +| P1 #1 | AAD encryption | **DEFERRED** | — | + +--- + +## Open follow-ups (priority order) + +### 1. Aggregator cross-check before orphan recovery (P2 #1 follow-up) — **SHIPPED** + +> **Status (2026-05-20)**: LANDED. `PaymentsModule.defaultOrphanRecovery` (`modules/payments/PaymentsModule.ts:~3725-3800`) now extracts the source state hash from the orphan token's `sdkData` and queries `oracle.isSpent(sourceStateHash)` BEFORE flipping status. The three branches per the original acceptance criteria are all in place: +> +> - aggregator UNSPENT → safe to restore (flips `'transferring'` → `'confirmed'`, persists, returns `'recovered'`). +> - aggregator SPENT → escalate to manual triage (returns `'manual'` with a forensic `logger.error` carrying the state hash + operator-action guidance). +> - aggregator RPC throws OR state hash unparseable → fail-closed to manual triage (returns `'manual'` with a `logger.warn`). +> +> The safety-contract precondition the original criteria listed for the default-ON flip is now satisfied. `features.orphanAutoRecovery` remains default-OFF pending the soak validation tracked under item #5. + +**Why it matters**: today `defaultOrphanRecovery` (gated by `features.orphanAutoRecovery`, default-OFF) flips orphan token status from `'transferring'` to `'confirmed'` based purely on "not in OUTBOX or SENT." This assumes the spending commit never reached the aggregator. In the rare race where the commit DID land (crash happened between `commitSources` returning and `outbox.create` writing), the restored token's local state hash drifts from the aggregator's view — the next operation surfaces a confusing state-mismatch error. + +**Acceptance criteria**: +- Before flipping status, query the aggregator for the source token's commitment state via `OracleProvider`. +- If aggregator has NO commitment → safe to restore (current behavior). +- If aggregator HAS a commitment → return `'manual'` (operator triage required because the source IS burned on-chain; recovery would require re-packaging the bundle, which is out of scope). +- Once this lands, `features.orphanAutoRecovery` can be flipped from default-OFF to default-ON. + +**Files**: +- `modules/payments/PaymentsModule.ts:~3430` — `defaultOrphanRecovery` private method +- `modules/payments/transfer/orphan-spending-sweeper.ts` — sweeper passes finding to recovery hook +- `oracle/oracle-provider.ts` — find the right API to query commitment state + +**Complexity**: Medium. New aggregator round-trip per orphan. Tests need a stub oracle that returns "present" / "absent" for specific token states. + +**Blast radius**: Low — gated behind default-OFF flag until soak-tested. + +--- + +### 2. Automatic re-publication of detected retention drops (P2 #3 follow-up) — **SHIPPED** + +> **Status (2026-05-20)**: SHIPPED with the Item #6.a prerequisite landed (PR #188) and the default `republish` closure downgraded (PR #189). The `NostrPersistenceVerifier` worker detects retention drops and emits `transfer:retention-warning`; the `SendingRecoveryWorker` re-publishes via the OUTBOX `delivered → sending` transition; the default `republish` closure in `PaymentsModule` (`~line 1937`) now produces a `'uxf-cid'` payload for both `cid-over-nostr` AND `car-over-nostr` entries — Item #6.a guarantees the CID is fetchable from the sender's local IPFS node for all post-deploy entries. Item #15's snapshot sync eliminates the cross-device `'entry-tombstoned-or-missing'` skip. Operators with pre-#6.a legacy entries that lack a local pin can opt into the strict-throw behavior by installing a custom `republish` closure via `installSendingRecoveryWorker()`. +> +> **Scope after Item #15**: under full-profile-snapshot sync, OUTBOX entries propagate across peers via the pointer mechanism, so the `'entry-tombstoned-or-missing'` skip-reason on `transfer:retention-republish-skipped` becomes rare. Bundles remain pinned on our IPFS by definition (IPFS-pin-only directive — Item #6.a closed the inline-CAR gap); re-publishing always has the bundle bytes available via CID. See Item #15. +> +> **Locked by test** (commit `340f65d`): `tests/integration/profile/retention-republish-after-snapshot-join.test.ts` (3 tests) demonstrates the elimination of the `'entry-tombstoned-or-missing'` skip on the cross-device path. The "with snapshot JOIN" scenario asserts that after Peer A's delivered OUTBOX entry propagates to Peer B via the lean-snapshot pull, B's verifier successfully re-arms the retention re-publish (`transfer:retention-republish-rearmed`) instead of skipping. A baseline test without the JOIN step preserves the pre-Item-#15 behaviour as the contrast (the skip DOES fire) so the test scenario actually exercises the contrast. An idempotency test locks the verifier's `checkedIds` semantics. **Updated in PR #189**: `tests/unit/modules/payments/recovery-worker-shim.test.ts` now asserts that CAR-mode entries downgrade to `'uxf-cid'` on re-publish (rather than throwing). + +**Why it matters**: today `NostrPersistenceVerifier` (default-OFF) detects a relay retention drop and emits `transfer:retention-warning`. That's all. The bundle was successfully delivered earlier (relay ack'd it) but is now gone — the recipient may have already seen it, may not have. Closing the loop means actually re-publishing. + +**Acceptance criteria**: +- On `'missing'` outcome from `transport.verifyTokenTransferRetained`, transition the OUTBOX entry from `'delivered'`/`'delivered-instant'` back to `'sending'` (or new `'retention-republish-pending'` status — needs §7.0 state-machine edit). +- `SendingRecoveryWorker` then picks up the entry and re-publishes via its existing `republish` callback. +- The SENT entry stays put (it's the durable record; re-publishing doesn't unmake the historical delivery). +- Idempotency: the recipient's replay-LRU short-circuits duplicates by `bundleCid` (§6.3 / T.3.A), so re-publish is safe to fire multiple times. + +**Surface area concerns**: +- Bundle payload preservation: if the original CAR was inline (`uxf-car`), the bundle bytes must still be reachable. Today they're not stored after the initial publish. Need to either (a) store the CAR locally for the retention window, or (b) downgrade re-publishes to CID-mode (requires the IPFS pin still being valid). The latter is simpler if the pin TTL exceeds the retention window. +- Recipient identity binding: if the recipient rotated keys since the original publish, re-publishing to the old key fails silently. Need a re-resolve step before re-publish. +- Key rotation on sender side: if sender rotated since publish, the original event was signed with the old key. Republishing with the new key has different event id; recipient sees it as a new event (deduplication by bundleCid still works). + +**Files**: +- `modules/payments/transfer/nostr-persistence-verifier.ts` — current emit-only behavior +- `modules/payments/transfer/sending-recovery-worker.ts` — recovery worker (would handle re-publish via existing mechanism) +- `profile/outbox-state-machine.ts` — §7.0 transition table (may need a new arc) +- `modules/payments/PaymentsModule.ts:~1715-1740` — the `republish` callback the recovery worker calls + +**Complexity**: Large. Probably needs its own design doc + multiple PRs (state-machine edit, bundle-payload retention, re-resolve path, etc.). + +**Blast radius**: Medium. Default-OFF feature flag, but touches the §7.0 state machine. + +--- + +### 3. `SentLedgerWriter.contains()` in-memory index (P4 #3 follow-up) — **SHIPPED** + +> **Status (2026-05-20)**: LANDED. `SentLedgerWriter` (`profile/sent-ledger-writer.ts:~142`) carries a lazy `tokenIndex: Map>` populated on first `contains()` / `findByTokenId()` call via `ensureIndex()`. The companion `entryTokenIds` map lets `write()` / `delete()` maintain the index incrementally without re-decrypting. Cross-replica staleness defense (see the verify-on-hit step in `contains()`) handles the case where a remote peer tombstones an entry our in-memory index still references. Both methods are now O(1) on the miss path and O(b) on the hit path, where b is the bucket size (typically 1). The cost-contract test at `tests/unit/profile/sent-ledger-writer.test.ts` was updated alongside. + +**Why it matters**: `contains(tokenId)` is O(n × m) — prefix-scan SENT, decrypt every entry, scan tokenIds. The duplicate-bundle guard (now active by default) calls `contains` per-token per-send. At ~1000 SENT entries × ~4 tokenIds = 4000 decrypts per send. Acceptable today; bad at higher SENT volumes. + +**Acceptance criteria**: +- Add a lazy in-memory index `Map>` to `SentLedgerWriter`. +- Populated on first `readAll()` call; updated on every `write()` and `delete()`. +- `contains()` uses the index for O(1) lookup. +- Index is local (not persisted) — re-derived from `readAll()` on each Sphere instantiation. +- Cost contract test from #167 P4 #3 should be updated to verify the O(1) behavior once the index is in place. + +**Files**: +- `profile/sent-ledger-writer.ts:~250-275` — current `contains()` + `findByTokenId()` +- `tests/unit/profile/sent-ledger-writer.test.ts:~368-403` — existing cost-contract test that pins O(n × m); update for O(1). + +**Complexity**: Small. Pure in-memory data-structure change. + +**Blast radius**: Low. Behavior-preserving optimization. + +--- + +### 4. Storage GC for tombstones — **SHIPPED** + +> **Status (2026-05-20)**: LANDED. `OutboxWriter.gcExpiredTombstones` (`profile/outbox-writer.ts:~452`) and `SentLedgerWriter.gcExpiredTombstones` (`profile/sent-ledger-writer.ts:~296`) sweep tombstoned slots where `now - deletedAt > retentionMs` (default 30 days) and call `db.del()` to reclaim OrbitDB log bytes. The companion `TombstoneGcWorker` (`modules/payments/transfer/tombstone-gc-worker.ts`) drives the periodic sweep when `features.tombstoneGcWorker` is enabled. Under Item #15, the snapshot builder also drops expired tombstones at publish time via the `gcExpiredTombstones` hook on `BuildLeanProfileSnapshotOptions` (commit `0f530eb`). The default-ON flip for `features.tombstoneGcWorker` is tracked under item #5. + +**Why it matters**: tombstones are `db.put(marker)` not `db.del()`. The OrbitDB log grows monotonically. Long-running wallets accumulate dead-key bytes forever. + +**Acceptance criteria**: +- Periodic worker (or sweep at load time) finds tombstoned slots where `now - deletedAt > retentionMs` (configurable, default 30 days). +- For each, call `db.del(key)` to actually reclaim storage. +- Retention window must be long enough that no concurrent replica's pre-sync state could revive the slot. 30 days is conservative; could be tightened with measurement. +- Test: write entry, delete, advance clock past retention, sweep, verify `db.get()` returns null AND OrbitDB log no longer contains the key. + +**Files**: +- New worker module: `modules/payments/transfer/tombstone-gc-worker.ts` (proposed) +- `profile/outbox-writer.ts` — needs a new method to enumerate tombstoned slots (currently they're invisible to all read paths) +- `profile/sent-ledger-writer.ts` — same + +**Complexity**: Medium. The "enumerate tombstoned slots" path is new code; the worker structure can copy from `SentReconciliationWorker`. + +**Blast radius**: Medium. Touches the storage layer directly; bug in retention math could prematurely delete tombstones and re-enable resurrection. + +--- + +### 5. Soak validation + default-ON flip for the new workers — **SHIPPED** + +> **Status (2026-05-20)**: All four soak-gated flags have flipped to default-ON. Wallets can still opt out explicitly per flag. +> +> - `features.spentStateRescan` — **FLIPPED default-ON** in PR #178 (Item #16). Default closure does archive + tombstone + map-delete via `removeToken`; durable `_audit` record via PR #179 when DispositionWriter is wired. +> - `features.orphanAutoRecovery` — **FLIPPED default-ON** in PR #181. Item #1's aggregator cross-check prerequisite is satisfied (`PaymentsModule.defaultOrphanRecovery` queries `oracle.isSpent(sourceStateHash)` before flipping status and escalates to `'manual'` when the aggregator reports the source state spent). Without this flip a crashed send leaves the source token unspendable indefinitely; with it, the load-tail orphan sweep auto-recovers. +> - `features.tombstoneGcWorker` — **FLIPPED default-ON** in PR #184. The 30-day default retention is conservative — longer than any realistic concurrent-replica pre-sync window per Issue #166 P1 #2 safety contract — so swept slots cannot be resurrected by a stale replica. The worker self-skips when no OUTBOX or SENT writer is installed, so the flip is a safe no-op for legacy-only wallets. Tests can opt out with `features.tombstoneGcWorker: false` (timer-sensitive paths). +> - `features.nostrPersistenceVerifier` — **FLIPPED default-ON** in this PR. Query traffic is proportional to eligible SENT volume with an LRU-bounded cap and per-entry cooldown (default 5 minutes); the worker self-skips wallets with no `nostrEventId`-tagged SENT entries (legacy pre-#166 P2 #3). On `'missing'` outcome the verifier re-arms the OUTBOX entry to `'sending'` so the recovery worker republishes via Item #2's path. Deployments on restrictive relay sets that cannot absorb the steady load should set `features.nostrPersistenceVerifier: false` explicitly. + +**Why it matters**: two new workers landed in default-OFF state pending soak validation: +- `features.nostrPersistenceVerifier` — adds relay query traffic +- `features.orphanAutoRecovery` — has the unsafe-race trade-off (item #1 above) + +Until flipped to default-ON, these are dead code for any wallet that doesn't explicitly opt in. + +**Acceptance criteria**: +- For each flag, run soak in a non-production environment for at least 7 days with the flag ON. +- Measure: relay query rate (for verifier), false-positive orphan recoveries (for recovery — should be zero after item #1 lands). +- Document soak findings; flip the flag default to `true` in `PaymentsModule.ts:~1440-1460` (`features` defaults block). +- Update tests that explicitly disable these flags via `features: { ... = false }` — those tests run with the default; flip is backward-compatible. + +**Files**: +- `modules/payments/PaymentsModule.ts:~1419-1450` — feature defaults block +- `tests/unit/modules/payments/__fixtures__/payments-module-fixture.ts` — many test fixtures disable workers; review what should change + +**Complexity**: Small change once soak proves safe. Soak itself takes time. + +**Blast radius**: Low — the workers are designed to self-skip when prerequisites missing. + +--- + +### 6. Re-publish on CAR vs CID modes — bundle availability + +> **Scope after Item #15**: per the IPFS-pin-only architectural directive, every bundle (regardless of original Nostr delivery mode) is pinned on our IPFS node. The CAR-mode re-publish throw added in commit `72879d1` becomes a defensive fallback rather than the common case — `'cid-over-nostr'` re-publish using the SENT entry's `bundleCid` always succeeds when the pin is live. See Item #15. +> +> **Audit verdict (2026-05-19, per ITEM-15-OPERATIONAL-CLOSURE-PROMPT.md gap #4): the throw is NOT YET demotable.** The IPFS-pin-only directive is aspirational; the senders' `modules/payments/transfer/delivery-resolver.ts:resolveDelivery` currently invokes `publishToIpfs` ONLY on the CID branches (`'force-cid'` and `'auto'` over-cap with publisher wired): +> +> - `'force-inline'` → `{ kind: 'inline', carBase64 }` — **NO pin call.** +> - `'auto'` ≤ inlineCap → `{ kind: 'inline', carBase64 }` — **NO pin call.** +> - `'auto'` over-cap, no publisher, bundle ≤ `RELAY_SAFE_CAP_BYTES` → `carInlineFallback` returns inline — **NO pin call.** +> - `'auto'` over-cap with publisher → `{ kind: 'cid', cid, shouldPin: true }` — pin call IS made. +> - `'force-cid'` (requires publisher) — pin call IS made. +> +> So entries recorded with `deliveryMethod='car-over-nostr'` were inlined on the Nostr wire and **never pinned to the sender's IPFS node**. The default `republish` closure's CAR-mode throw in `PaymentsModule.ts` is therefore still the correct behaviour today for those entries — there is no IPFS pin to fall back to via `'cid-over-nostr'` re-publish. The throw routes the entry to `'failed-transient'` via the recovery worker's `maxRetries` mechanism, which is the §7.0 escape valve for operator triage. +> +> **Residual gap (sub-item 6.a — NEW)**: implement the IPFS-pin-only directive at send time by extending `delivery-resolver.ts` so the `'inline'` branches ALSO call `publishToIpfs` (or an equivalent local-pin function) for the same content-addressed CAR bytes. Once that change lands, the sender's IPFS node holds the pin for every bundle regardless of wire delivery mode, the SENT entry's `bundleCid` is reliably fetchable, and the default `republish` closure can downgrade `'car-over-nostr'` re-publishes to `'cid-over-nostr'` shape unconditionally. The current throw then truly becomes the defensive-fallback the doc anticipated. Tracked here as part of Item #6's acceptance criteria; spec-text revision suggested: "Acceptance criteria for 6.a: every successful send (any delivery mode) leaves a live IPFS pin on the sender's local node for `bundleCid`; CAR-mode re-publish closure downgrades to CID-over-Nostr; the throw becomes unreachable in the common case (only reached when the pin TTL has expired AND the bundle bytes are also gone from local storage)." + +**Why it matters**: `SendingRecoveryWorker.republish` (the default in PaymentsModule) ships `kind: 'uxf-cid'` for every re-publish, regardless of the original delivery mode. For an entry originally delivered via `kind: 'uxf-car'` (inline CAR), the IPFS pin may not exist — the recipient gets a CID they can't fetch. + +**Acceptance criteria**: +- Default `republish` closure inspects `entry.deliveryMethod`: + - `'car-over-nostr'` → re-publish inline CAR. Requires storing the CAR bytes locally for the retention window OR re-pinning to IPFS. + - `'cid-over-nostr'` → re-publish CID (current behavior). +- If CAR bytes unavailable AND re-pin fails, log an error and transition entry to `'failed-transient'` so an operator sees it. + +**Files**: +- `modules/payments/PaymentsModule.ts:~1715-1740` — default `republish` closure +- `modules/payments/transfer/sending-recovery-worker.ts` — re-publish call + +**Complexity**: Medium. Bundle storage is a real architectural concern. + +**Blast radius**: Low if gated behind the existing `features.recoveryWorker` flag (default-ON but already in production). + +--- + +### 7. `lamport: 0` synthetic placeholder — **SHIPPED** + +> **Status (2026-05-20)**: LANDED. `writeSentEntryFromOutbox` (`PaymentsModule.ts:~3507`) was refactored to accept `OutboxCreateInput` (the orchestrator's input shape that does NOT include `_schemaVersion` or `lamport`). Both callers (`dispatchUxfInstantSend` at `:~12782` and the conservative dispatcher) pass their existing `OutboxCreateInput` directly — no synthetic placeholder construction. The helper's JSDoc explicitly notes: "neither caller's `lamport` is read here; the SENT ledger writer stamps its own Lamport on `write()`." The misleading-`0` foot-gun is gone; the type system now prevents reintroducing it. Verified via `grep -n "lamport: 0" PaymentsModule.ts` — no remaining occurrences beyond the doc comment at line 12780 that references this resolution. + +**Why it matters**: `PaymentsModule.ts:~12108` synthesizes a `UxfTransferOutboxEntry` with `lamport: 0` purely so `writeSentEntryFromOutbox` can read fields off it. The `0` is a placeholder — it doesn't correspond to any real CRDT clock value. If a future code path uses `lamport` from the synthesized entry, it gets a misleading 0. + +**Acceptance criteria**: +- Either thread the real Lamport from the writer's return value, or change `writeSentEntryFromOutbox`'s contract to accept an input shape that doesn't include `lamport`. +- Tests verify the SENT entry's Lamport is `>= max(observed)` not 0. + +**Files**: +- `modules/payments/PaymentsModule.ts:~12099-12114` — the synthetic-construction site +- `modules/payments/PaymentsModule.ts:~3239-3275` — `writeSentEntryFromOutbox` helper + +**Complexity**: Small. + +**Blast radius**: Low. Cosmetic / type-correctness fix; no behavior change today because nothing reads the synthetic's `lamport`. + +--- + +### 8. Legacy KV outbox removal + +**Why it matters**: dispatchers still dual-write to the legacy KV outbox (`saveToOutbox`/`removeFromOutbox`) AND the profile-resident `OutboxWriter`. The legacy path was "preserved during the transition window" per #97's landing notes. No documented end-date. + +**Acceptance criteria**: +- Audit all callers of `saveToOutbox`/`removeFromOutbox`.

Concurrent-replica integration tests + +> **Scope after Item #15**: the OrbitDB Hash Log layer is no longer the conflict-resolution layer for OUTBOX/SENT — the snapshot pointer + per-writer JOIN takes over. The residual "real-OrbitDB-log lex-sort gap" largely dissolves; the meaningful test surface moves to "two peers concurrently flushing snapshots → JOIN convergence". See Item #15 Phase G for the new test scenarios. + +**Status (2026-05-18)**: Writer-layer scope **MERGED** on `integration/all-fixes` (commit `0b169f7`). Real-OrbitDB-log scope **STILL OPEN**. + +**Scope clarification.** Originally this item was framed as "OrbitDB Hash Log lex-sort conflict resolution between concurrent profile peers." A subsequent architectural review (see "Pointer-layer vs OrbitDB-log layering" in Cross-cutting concerns below) showed that framing conflated two different layers: + +- **Profile-state convergence** — "which CAR is the current profile?" — is resolved by the **aggregator pointer mechanism**, not by OrbitDB log layer. Each profile flush publishes a CID to the Unicity aggregator (`profile/aggregator-pointer/*`, `profile/lifecycle-manager.ts`); peer reconciliation reads the latest authoritative pointer, fetches its CAR from IPFS, and JOINs into local state via `pointer-wiring.ts:buildFetchAndJoin`. OrbitDB's pubsub is wired but **demoted to a hint channel** that triggers an aggregator poll. OrbitDB's LWW lex-sort only arbitrates which small `tokens.bundle.{cid}` ref survives a concurrent same-key write — and the IPFS-level JOIN then operates over all bundle refs present regardless of which LWW win put each one there. **No correctness gap at this layer.** + +- **Per-entry-key OUTBOX/SENT writes** — the `${addr}.outbox.${id}` and `${addr}.sent.${id}` slots written directly by `OutboxWriter` / `SentLedgerWriter`. **These are NOT pointer-published.** They are not bundled into CARs. Their conflict resolution is OrbitDB's Hash Log layer (LWW lex-sort on entry hashes for concurrent writes to the same key). The CRDT machinery shipped under #166 P1 #2 (Lamport stamps + tombstones + refuse-write guard) is the right layer of defense for these — and **this is the layer this item now targets**. + +**What MERGED covers (writer-layer)** + +`tests/integration/profile/concurrent-replica-outbox.test.ts` exercises every invariant the writer layer can guarantee against concurrent peers via a shared-storage two-writer harness (one `MockProfileDb` shared between two `OutboxWriter` / `SentLedgerWriter` instances with separate Lamport clocks). 11 tests cover: +- Refuse-write guard across writer instances (post-sync resurrection blocked). +- Lamport monotonicity across writers, including observing remote *tombstone* Lamports. +- Pre-sync race resolution (tombstone-arrives-first → guard fires; live-write-arrives-first → tombstone wins on subsequent reads). +- SentLedgerWriter mirrors the same invariants, including cross-instance `contains()` index visibility after item #3. + +**What's STILL OPEN (real-OrbitDB-log layer)** + +Real `@orbitdb/core` Hash Log lex-sort under live libp2p replication is not exercised. Specifically: two replicas write the **same** OUTBOX/SENT key at the **same Lamport** before either sees the other. OrbitDB picks one via lex-sort on entry hashes; the loser's write is lost. The writer-layer refuse-write guard catches POST-sync resurrection attempts, but does NOT catch the PRE-sync race where both writes land "first" from their own perspective. See the "Lamport-on-tombstone" cross-cutting concern below for the full closure path. + +**Acceptance criteria (residual scope)**: +- Extend `OrbitDbAdapter` to support a two-peer test mode (currently `bootstrapPeers: []` isolated only).

Item #15 (Full Profile State Snapshot Sync) is LANDED — the per-entry-key Lamport+tombstone machinery is now load-bearing as the JOIN merge function at snapshot-pull time. The vector-model alternative loses its appeal. No migration is planned; the per-entry-key design is the canonical choice. The future-ADR pointer below stays for historical context. + +> **Resolved by Item #15 (per-entry-key wins)**: under full-profile-snapshot sync, the per-entry-key Lamport+tombstone machinery becomes the JOIN merge function at snapshot-pull time. The complexity that was "paid for multi-replica CRDT safety" is now load-bearing for snapshot-time JOIN. The vector-model alternative loses its appeal. This item can be marked resolved once Item #15 lands. + +**Why it matters**: in our prior conversation we surfaced that the per-entry-key OUTBOX design exists for multi-replica CRDT safety. Tombstones, Lamport bookkeeping, hydration-race handling, and the refuse-write guard are all complexity paid for that safety. If the project commits to "one active writer per wallet at a time" as a constraint, a single-vector approach (whole OUTBOX as one OrbitDB value, rewritten on add/remove) drops ~1000+ lines. + +**Acceptance criteria**: +- Maintainer decision documented: either "multi-replica is a hard requirement" (keep current design) or "single-writer is an acceptable constraint" (begin migration to vector model). +- If migrating: design doc covering the migration path, on-disk format change, and how SENT (currently per-entry-key for a good reason — append-only) would or would not also migrate. +- If keeping: document the multi-replica use case explicitly so future contributors understand the cost. + +**Files**: +- New: `docs/uxf/ADR-XXX-outbox-storage-model.md` (proposed) + +**Complexity**: The decision is small; the migration (if chosen) is Large. + +**Blast radius**: N/A for the decision; Very High for migration. + +--- + +### 11. Operator runbooks for the new events — **SHIPPED** + +> **Status (2026-05-20)**: LANDED. `docs/uxf/RUNBOOK-SEND-PIPELINE.md` covers all five Issue #166 events (`transfer:orphan-spending-detected`, `transfer:orphan-recovered`, `transfer:sent-reconciliation-recovered`, `transfer:sent-reconciliation-failed`, `transfer:retention-warning`) PLUS the post-#166 additions (`transfer:retention-republish-rearmed`, `transfer:retention-republish-skipped` from Item #2; `transfer:off-record-spent` from Item #16). Each section follows the same template: payload shape, what it means, system state, diagnostic data to collect, action checklist. The runbook is cross-referenced from `CLAUDE.md` ("Operator runbooks for the send-pipeline events live at `docs/uxf/RUNBOOK-SEND-PIPELINE.md`"). + +**Why it matters**: Issue #166 added five new operator-facing events. None have documented runbooks: +- `transfer:orphan-spending-detected` +- `transfer:orphan-recovered` +- `transfer:sent-reconciliation-recovered` +- `transfer:sent-reconciliation-failed` +- `transfer:retention-warning` + +Operators receiving these have no documented "do this" guidance. + +**Acceptance criteria**: +- New doc `docs/uxf/RUNBOOK-SEND-PIPELINE.md` with a section per event. +- For each: what the event means, what state the system is in, what diagnostic data to collect, what actions to take. +- Reference from CLAUDE.md. + +**Files**: +- New: `docs/uxf/RUNBOOK-SEND-PIPELINE.md` +- `CLAUDE.md` — add a pointer + +**Complexity**: Small (writing only). + +**Blast radius**: None — documentation. + +--- + +### 12. Consumer-facing API docs for new events — **SHIPPED** + +> **Status (2026-05-20)**: LANDED. `CLAUDE.md`'s "Key Events" table lists all five Issue #166 events plus the post-#166 additions (`transfer:retention-republish-rearmed`, `transfer:retention-republish-skipped`, `transfer:off-record-spent`). Each row carries the canonical payload shape + a one-line "When" description. `SphereEventMap` in `types/index.ts` carries full per-event JSDoc with the same payload semantics. + +**Why it matters**: same five events lack public API documentation. Apps consuming `sphere.on('transfer:...')` need to know the payload shapes and when they fire. + +**Acceptance criteria**: +- Add each event to `CLAUDE.md`'s "Key Events" table. +- Update `docs/API.md` (if it exists) or wherever the public event reference lives. + +**Files**: +- `CLAUDE.md` lines around the "Key Events" table + +**Complexity**: Small (writing only). + +**Blast radius**: None. + +--- + +### 13. AAD per-record encryption (P1 #1 — DEFERRED) + +**Status**: deliberately deferred per maintainer call. Not on the near-term roadmap. + +**Why it's deferred**: implementing requires threading `AAD = TextEncoder().encode(fullKey)` through every `encrypt` / `decrypt` call across all profile writers: `OutboxWriter`, `SentLedgerWriter`, `DispositionWriter`, `FinalizationQueueStorageAdapter`, `RecipientContextStorageAdapter`. Project-wide change. + +**Risk if left undone**: the keyspace ciphertext-lift attack documented in `profile/encryption.ts:85-94` — an attacker with OrbitDB write access can swap encrypted blobs between any two keys that share the same encryption key. Two writers sharing the same key (e.g. outbox + sent on same address) can have ciphertext lifted from one keyspace into the other. + +**When to revisit**: when threat model includes peers with OrbitDB write access, or when peer-replicated profile writers are extended to a new data type that warrants the audit. + +**Files** (for the future): +- `profile/encryption.ts` — current `encryptProfileValue` / `decryptProfileValue` signatures +- Every callsite of those two functions (search for them with `grep -rn`) + +--- + +### 14. Multi-device concurrent double-spend reconciliation (NEW 2026-05-18) + +**Why it matters**: when two peers share the same Profile (e.g. desktop + mobile signed into the same wallet) and concurrently spend the SAME token T to DIFFERENT destination addresses, the L3 aggregator anchors exactly ONE commitment (the source `stateHash` can only be spent once). The other peer's `submitTransferCommitment` throws. The codebase handles the on-chain safety correctly — no double-delivery of value — but the LOSER's local state is left in an inconsistent state that the system has the information to fix automatically but currently doesn't. + +**Background evidence** (from the 2026-05-18 code investigation): + +- Aggregator-level: only one commit lands. `PaymentsModule.ts:11207-11212` throws on the loser's `submitTransferCommitment` rejection. **The throw is not caught with a state-recovery handler** — the loser's source token stays at `status='transferring'` indefinitely. +- Balance: `aggregateTokens` (`PaymentsModule.ts:~7001-7048`) correctly excludes `'transferring'` tokens from `confirmedAmount` (spendable balance is conservative). BUT it INCLUDES them in `unconfirmedAmount` and `totalAmount`. **Loser's unconfirmed balance is inflated by the token's value indefinitely.** +- JOIN at sync: contrary to the stale comment at `profile/pointer-wiring.ts:36-40`, the per-token resolver `resolveTokenRoot` (`uxf/token-join.ts:210-330`) IS implemented and IS wired by `profile-token-storage-provider.ts:683-773`. It ranks chain heads by `(committedCount DESC, length DESC, rootHash ASC)` and surfaces incompatible chains as `kind: 'divergent'`. Rule 4 enrichment fires when an oracle is wired (`verifyInclusionProof`). +- Orphan sweeper: `defaultOrphanRecovery` (post-item-#1) correctly returns `'manual'` for the loser's stuck token (aggregator says SPENT — but by the winner's commit, not by the loser's). Emits `transfer:orphan-spending-detected`. **This conflates a crash-window orphan with a concurrent-peer double-spend loss.** + +So the JOIN layer already knows the truth. The OUTBOX state machine and the local Token status do not learn it. + +**What works correctly today** + +- No fund double-spend. The L3 aggregator is the conflict authority. +- No spendable-balance corruption. Both peers correctly exclude `'transferring'` tokens from confirmed/spendable balance. +- JOIN-time resolution. When both peers' profiles are merged on any device (post-sync), the on-chain winner's chain head is deterministically preferred. +- Audit trail. Loser's failed OUTBOX entry is preserved. + +**Acceptance criteria** (numbered work items; can be split into separate PRs): + +1. **Classify the aggregator rejection.** Tag the throw at `PaymentsModule.ts:11207-11212` with a typed `SphereError` code distinguishing `STATE_ALREADY_SPENT_BY_OTHER` from generic commit failure. The aggregator response should carry enough metadata to detect "the state IS spent — but by a commit whose recipient differs from the one we just tried to submit." Where it doesn't, the dispatcher re-queries `oracle.isSpent(sourceStateHash)` to disambiguate. + +2. **Dispatcher catch + state transition.** On `STATE_ALREADY_SPENT_BY_OTHER`: + - Move the OUTBOX entry to a terminal `'failed-conflict'` status (NEW — see #3 below). The bundle was never delivered; the entry is a forensic record of the lost race. + - Restore the source token's `status` from `'transferring'` to a state that reflects "spent by another peer" — proposal: a new `'spent-by-other'` status (or reuse `'spent'` with an `error`-style marker) so balance computation excludes it from `unconfirmedAmount` as well as `confirmedAmount`. + - Emit the new `transfer:double-spend-detected` event (see #4). + +3. **§7.0 state-machine: add `'failed-conflict'` status + arcs.** New canonical UxfOutboxStatus. Reachable via `sending → failed-conflict` (and possibly `packaging → failed-conflict` if the commit throws very early). Terminal — no outgoing arcs except the operator override (mirrors `'failed-permanent'`). Update `outbox-state-machine.test.ts` snapshot count (19 → 21 rows assuming two new arcs). + +4. **New event `transfer:double-spend-detected`.** Payload: `{ tokenId, sourceStateHash, ourIntendedRecipient, winningChainHead?, detectedAt }`. Distinct from `transfer:orphan-spending-detected` (crash-window) so operators / UIs can route them differently. Add to `SphereEventMap` in `types/index.ts` and to the Key Events table in `CLAUDE.md`. Operator action documented in `docs/uxf/RUNBOOK-SEND-PIPELINE.md`. + +5. **Wire JOIN divergent outcome → local Token.status.** When `UxfPackage.merge` produces a `divergent` outcome and the winning rootHash is NOT the local belief, update the local Token (`status`, `sdkData`) to reflect the winner's chain head. Today this signal is computed inside the resolver and used to write the merged package, but the consumer (`PaymentsModule`'s token cache) doesn't observe the divergent flag — it just consumes the merged package's tokens. Tests: a JOIN-divergent test that asserts the local `Token.status` flips after merge. + +6. **Update the stale comment** at `profile/pointer-wiring.ts:36-40`. It currently claims Rules 3+4 are absent; the resolver landed and is wired. Replace with a forward reference to the resolver and to this item for the residual local-state-update wiring. + +7. **Orphan sweeper disambiguation.** When `defaultOrphanRecovery` finds the aggregator says SPENT, today it returns `'manual'` and emits `transfer:orphan-spending-detected`. Once #4's event lands, the sweeper should re-query the aggregator's commit DETAIL (which recipient was anchored?) and, if the anchored recipient ≠ this peer's local outbox entry's recipient, emit `transfer:double-spend-detected` instead. If aggregator returns ambiguous data or no detail, fall back to the legacy detected event. + +8. **`getAssets` / balance regression test.** Assert that a `'spent-by-other'` (or equivalent terminal) token is excluded from BOTH `confirmedAmount` and `unconfirmedAmount` — so the loser's UI numbers converge to the truth after reconciliation. + +**Files**: +- `modules/payments/PaymentsModule.ts:~11207-11212` — submit throw classification + dispatcher catch. +- `core/errors.ts` — new `STATE_ALREADY_SPENT_BY_OTHER` error code. +- `types/index.ts` — new `'transfer:double-spend-detected'` event + payload; possibly new `TokenStatus = 'spent-by-other'`. +- `profile/outbox-state-machine.ts` — new `'failed-conflict'` status + arcs. +- `tests/unit/profile/outbox-state-machine.test.ts` — row-count snapshot bump. +- `profile/profile-token-storage-provider.ts:~683-773` — wire JOIN divergent outcome to local Token.status. +- `modules/payments/transfer/orphan-spending-sweeper.ts` — disambiguation with aggregator detail. +- `modules/payments/PaymentsModule.ts` (`defaultOrphanRecovery` ~3462) — emit `transfer:double-spend-detected` when applicable. +- `profile/pointer-wiring.ts:36-40` — update stale comment. +- `CLAUDE.md` — add new event to Key Events table. +- `docs/uxf/RUNBOOK-SEND-PIPELINE.md` — add new event's operator section. + +**Complexity**: Medium. Cuts across the dispatcher, the §7.0 state machine, balance computation, and the JOIN consumer. Each work item (1-8) is small in isolation; the integration is the medium part. Tests must cover the multi-device scenario end-to-end with a deterministic loser/winner setup. + +**Blast radius**: Medium. New state-machine arcs require careful release coordination with already-deployed wallets (a wallet that hasn't learned about `'failed-conflict'` would treat it as an unknown status and the type guards would filter it out — same conservative behaviour as today). Local Token-status mutations on JOIN divergence are observable to UIs subscribed to `transfer:*` and `address:*` events; UI changes may be needed downstream. + +**Suggested PR split**: +- Phase 1 (small): items 1, 2, 4 — classify the throw, surface the new event, transition OUTBOX to `'failed-conflict'`. Don't yet update local Token.status — rely on the existing JOIN at next sync for that. Phase 1 alone is enough to stop the "stuck `'transferring'` forever" symptom for the operator-visible surface. +- Phase 2 (medium): items 3, 5, 7, 8 — proper §7.0 state-machine entry, JOIN→Token wiring, orphan sweeper disambiguation, balance regression test. Closes the unconfirmed-balance gap. +- Phase 3 (small): item 6 + the CLAUDE.md / runbook updates from work items 4 and 6 — docs cleanup. + +**Phase 1 implementation status (commit `9b4fae7`)** — DONE. + * Item #1 (typed throw): new `SphereErrorCode` `'STATE_ALREADY_SPENT_BY_OTHER'`; new private helper `PaymentsModule.submitCommitmentClassified(stClient, oracle, commitment, classify)` wraps both dispatcher submit-throw sites (`PaymentsModule.ts:~11207` conservative + `:~12036` instant). On non-success/non-idempotent response the helper re-queries `oracle.isSpent(sourceStateHash)` to disambiguate; on confirmed spent it raises the typed code with a structured `cause` payload (`tokenId`, `sourceStateHash`, `ourIntendedRecipient`, `submitStatus`). Probe throws / unspent / no-oracle paths fall back to the legacy `'TRANSFER_FAILED'` so transient and authenticator-failed cases remain unchanged. + * Item #3 (state machine): `UxfOutboxStatus` widened 10 → 11 with `'failed-conflict'` (hard-terminal partition). `ALLOWED_TRANSITIONS` widened 19 → 25 with five entry arcs (`packaging`/`pinned`/`sending`/`delivered`/`delivered-instant → failed-conflict`) plus the operator-override escape `failed-conflict → finalizing` (mirrors `failed-permanent`). Snapshot tests updated. Note: for greenfield sends the OUTBOX entry does not yet exist at the submit throw site (the conservative + instant senders create it AFTER `commitSources` returns), so today the operator-visible signal is the emitted event itself; the §7.0 arcs cover future recovery paths that hit the spent state on a previously-created entry. + * Item #4 (event): new `'transfer:double-spend-detected'` event + payload (`tokenId`, `sourceStateHash`, `ourIntendedRecipient`, `detectedAt`) wired into both dispatcher outer-catches via `PaymentsModule.emitDoubleSpendDetectedIfApplicable(err)`. Defensive: tolerates missing payload fields (empty-string defaults rather than skipping); emit failures are logged and swallowed. + * Tests: `tests/unit/modules/PaymentsModule.double-spend-detection.test.ts` (13 tests covering SphereErrorCode contract, SphereEventMap payload shape, `emitDoubleSpendDetectedIfApplicable`, and `submitCommitmentClassified`). + +Phase 2 work item 5 (JOIN→local-Token correction) LANDED on 2026-05-20. `loadFromStorageData` (`modules/payments/PaymentsModule.ts:~15043+`) now detects the JOIN-divergent loser case at restore time: when a preserved-from-memory token at `status='transferring'` shares a `genesisTokenId` with a winner-state storage token but has a DIFFERENT current state hash, the L3 aggregator has already arbitrated against the local in-flight send. The loser is dropped (not restored), an event `transfer:double-spend-detected` is emitted (reusing the Item #14 Phase 1 surface — the reactive submit-time path and this JOIN-time path emit the SAME event so operators can correlate without distinguishing the source). For non-`'transferring'` snapshot statuses the dual-state restore is preserved; the spent-state rescan worker (Item #16, default-ON) catches the off-record-spend on its next 5-min `oracle.isSpent` probe and routes through `defaultSpentStateTransition`. + +Phase 2 work item 7 (orphan sweeper disambiguation — distinguish multi-device double-spend from crash-window orphan) remains open — forensic / observability surface, not a correctness path now that work item 5 closes the `unconfirmedAmount` inflation. + +**Phase 2 work item 8 (balance regression test) LANDED 2026-05-20.** New test in `tests/unit/modules/PaymentsModule.never-wipe.test.ts` (`drops the JOIN-divergent loser from every getAssets() balance bucket`): pins the post-PR-#182 contract end-to-end through `getAssets()` — the dropped loser's amount is absent from `confirmedAmount`, `unconfirmedAmount`, `totalAmount`, and every per-bucket count. Pre-PR #182 the loser would have inflated `unconfirmedAmount` (since `aggregateTokens` includes `'transferring'` tokens there); the bug fix removes the loser from `this.tokens` entirely so all three buckets correctly exclude it. + +**Phase 3 (work item 6 + docs cleanup) LANDED 2026-05-20.** The stale comment at `profile/pointer-wiring.ts:36-40` (which claimed Rules 3 + 4 were absent) was replaced with a forward reference to `resolveTokenRoot` (`uxf/token-join.ts:210`), its production callers (`UxfPackage.merge()` `~785`, `conflict-merger.ts:~351`), and the JOIN-divergent loser branch in `PaymentsModule.loadFromStorageData` (PR #182). `CLAUDE.md` Key Events table now includes the `transfer:double-spend-detected` row with payload shape AND both trigger sources (reactive submit-time + JOIN-time) named explicitly; the `transfer:off-record-spent` row was added at the same time. `docs/uxf/RUNBOOK-SEND-PIPELINE.md`'s "Companion events" mention of `transfer:double-spend-detected` (in the `transfer:off-record-spent` section) was updated to reflect both trigger sources. + +> **Note on scope after Item #15**: under the full-profile-snapshot sync (Item #15), OUTBOX entries propagate via the pointer mechanism, so the racing window where two peers can both reach the aggregator with conflicting commits collapses to the pointer poll interval (typically seconds, not the indefinite "until manual sync" of today). Phase 1 of Item #14 (typed throw + new event + `'failed-conflict'` status) still wanted as the operator-visible signal; Phase 2's local-Token correction is largely subsumed by Item #15's JOIN flow. + +--- + +### 15. Full Profile State Snapshot Sync (NEW 2026-05-18) + +**Status**: design confirmed; implementation pending. Replaces the current "pointer-points-to-UXF-bundle-CID" model with "pointer-points-to-full-profile-snapshot-CID". **No backward compatibility** — the pointer scheme moves cleanly to the new format; legacy UXF-bundle-only pointers will not be supported. + +**Why it matters**: today the aggregator pointer covers ONLY the UXF token bundle. OUTBOX, SENT, dispositions, finalization queue, recipient context, and all other per-writer profile state live in OrbitDB and do NOT propagate via the pointer mechanism. Cross-peer convergence for those writers relies on OrbitDB pubsub, which is wired but explicitly demoted to a hint channel (`profile/orbitdb-adapter.ts:243-246`, `profile/lifecycle-manager.ts:27-49`) — i.e. unreliable across NAT/firewalls and not authoritative. + +The architectural impact of that gap: a peer that mutates an OUTBOX entry (e.g. moves an in-flight send to status `'sending'`) and then crashes leaves NO trace another peer running the same profile can observe via the authoritative channel. The orphan-spending sweeper, duplicate-bundle guard, retention re-publish, and multi-device double-spend reconciliation (items #1, #2, #14) all paper over this gap with peer-local heuristics. The clean fix is to make the pointer authoritative for the FULL profile. + +**Architecture**: + +The pointer-publish payload changes from "UXF bundle CID" to "lean profile snapshot CID". A snapshot is a content-addressed CAR containing: +- All per-writer encrypted KV entries (OUTBOX, SENT, dispositions, finalization queue, recipient context, etc.). Ciphertext is preserved as stored in OrbitDB — the snapshot layer never decrypts. Security boundary remains the wallet mnemonic. +- All `tokens.bundle.*` references (CIDs only — the bundle CARs themselves are pinned separately on IPFS, unchanged). +- Schema-versioned root. + +Sync is: +1. **Mutation**: ANY writer mutation (OUTBOX/SENT/disposition/UXF token state) marks profile dirty. +2. **Flush**: FlushScheduler debounces, builds lean profile snapshot, pins to IPFS, publishes snapshot CID to aggregator at the next pointer version. +3. **Crash safety**: aggregator anchoring is irreversible. A peer that crashes immediately after publish leaves a durable record of its profile state at that version. +4. **Poll**: peers poll the aggregator (existing path). On new version detected, fetch snapshot CAR from IPFS, content-verify CID. +5. **JOIN per writer**: each writer's `joinSnapshot(remoteEntries)` applies CRDT merge against local OrbitDB state. Local-only entries SURVIVE (set union); overlaps resolved by Lamport+tombstone semantics already proven at the writer layer. +6. **Re-publish**: if JOIN produced any local change, mark dirty → next flush re-snapshots → next pointer version. +7. **Convergence**: two peers flushing concurrently race for version V+1; aggregator anchors one; loser re-polls, JOINs winner's snapshot with local, publishes V+2. Bounded by polling interval + aggregator round-trip. + +OrbitDB's role degrades to **local encrypted KV cache**. Its CRDT-replication features become unused at the conflict-resolution level. Pubsub stays as a hint channel ("wake up and poll the aggregator now") — already its current role per `lifecycle-manager.ts:27-49`. + +**What's already in the tree**: + +`profile/profile-export.ts` defines `ProfileSnapshot` v1 — a CAR containing encrypted KV entries + embedded bundle CAR bytes (`profile-export.ts:158-189`). Used today for manual export/import only (operator-facing "back up to file" flow). Hardening already done: schema versioning, size caps (256 MiB / 1 MiB per block / 8 MiB per value / 100k entries / 200k blocks), content-address verification on bundle blocks, deterministic encoding. **The serialization layer is ~70% there.** + +Two important deltas needed: +- **"Lean" snapshot variant** — bundle refs by CID only, no embedded CAR bytes. The fat format stays for the export/import CLI. Schema v2. +- **Filter reversal** — today's export filter strips `tokens.bundle.*` and `consolidation.*` (operational state for export). For sync these ARE needed; the new lean snapshot includes them. + +**Implementation status** (2026-05-19 — branch `feat/outbox-followups-item15-phase-a`) + +Phase A and most of Phase B have landed locally as a sequence of commits on the +branch above (not yet merged to `integration/all-fixes`).

Closing this requires BOTH migrating the manifest store to + OrbitDB persistence AND extending the JOIN primitive (option + a) or building a dedicated `ManifestStore.joinSnapshot()` + (option b on this surface).

Sibling type to v1 or v2 of the existing type — IMO sibling is cleaner. +- A.2 Builder `buildLeanProfileSnapshot(deps)` mirroring `exportProfile` but skipping bundle-byte embedding AND including the keys that the export filter drops. Determinism preserved (entries sorted by key, bundles by CID). +- A.3 Parse / verify `parseLeanProfileSnapshot(carBytes)` with the same content-address re-verification and size caps. Reject `version > 2`. +- A.4 Unit tests: builder/parser round-trip is byte-identical; size caps enforced; deterministic output. + +**Phase B — Per-writer snapshot/JOIN API** + +Each writer that lives in OrbitDB gains two methods: + +```typescript +interface ProfileSyncWriter { + snapshot(): Promise>; + joinSnapshot(remote: ReadonlyArray<{ key: string; encryptedValue: Uint8Array }>): Promise; +} +``` + +`snapshot()` is a prefix-scan + read-encrypted-bytes — trivial. + +`joinSnapshot()` applies CRDT merge.

Write-time invariants become JOIN-time merge functions. + +Unit tests per writer: every cell of the table above, plus idempotence (re-running JOIN on the same remote is a no-op). + +**Phase C — Mutation→flush trigger surface** + +- ✓ C.1 (commit `04e423e`). Every writer's mutation surface invokes a host-provided `notifyProfileDirty()` callback. Plumbed through OutboxWriter, SentLedgerWriter, PrefixSyncWriter, OrbitDb{Finalization,RecipientContext}StorageAdapter, BundleIndex via `host.notifyProfileDirty()`. Centralised wiring lives on `ProfileStorageProvider.setProfileDirtyNotifier(cb)` so all `build*` factories thread the same callback. +- ✓ C.2 (commit `a5a2a90`). `ProfileTokenStorageProvider` debounces incoming dirty signals over `dirtyFlushDebounceMs` (defaults to `flushDebounceMs`, configurable per-test). On fire, dispatches the host-injected `onProfileDirtyFlush?: () => Promise` callback (new option). Concurrent signals serialize through `dirtyFlushPromise`; mid-flush signals latch via `dirtyFlushPending` and re-arm a fresh debounce. Errors are caught and surfaced via `storage:error` with code `PROFILE_DIRTY_FLUSH_FAILED`. Shutdown cancels the timer and awaits in-flight callbacks. +- ✓ C.3 (commit `8c241e9`). `profile/factory.ts:createProfileProviders` wires the lean-snapshot dirty-flush closure into `ProfileTokenStorageProviderOptions.onProfileDirtyFlush` and registers a writer-side notifier on the storage provider that delegates to `tokenStorage.notifyProfileDirty()`. The closure body is exported as `runProfileDirtyFlush(deps)` for unit-testing without spinning up real OrbitDB / IPFS — it (1) reads `chainPubkey` / `network` from the live identity + config (bail on either missing), (2) verifies the pointer layer is ready (bail otherwise), (3) builds a lean snapshot via `buildLeanProfileSnapshot()`, (4) pins via `pinToIpfs(ipfsGateways, …)`, (5) publishes via `pointer.publish(cidProducer)`. `ProfileTokenStorageProvider.notifyProfileDirty()` is promoted to public (the factory bridge needs to call it from outside). New `ProfileTokenStorageProvider.getIdentity()` public accessor lets the closure read the live `chainPubkey` lazily without leaking the host adapter. Tests: `tests/unit/profile/factory-dirty-flush.test.ts` (10 tests covering bail paths, build→pin→publish ordering, error propagation, fresh-evaluation across calls) + `tests/unit/profile/integration.test.ts` (2 new wiring assertions). + +**Phase D — Pointer publish & pull integration** + +- D.1 `LifecycleManager.publishAggregatorPointerBestEffort(cid)` receives the SNAPSHOT CID, not the bundle CID. Existing publish-retry / version-monotonicity logic stays. +- D.2 `buildFetchAndJoin` (`profile/pointer-wiring.ts:387-533`) becomes: + 1. Fetch snapshot CAR by CID, content-verify. + 2. Parse via `parseLeanProfileSnapshot`. + 3. For each writer, dispatch the writer's `joinSnapshot()` over the writer's prefix-filtered entries. + 4. Write bundle refs to local OrbitDB (existing path; existing `UxfPackage.merge` at `load()` time runs over the merged ref set unchanged). + 5. Advance version cursor only after all per-writer JOINs persist. + 6. If JOIN produced any local change → mark profile dirty (next flush re-snapshots and publishes the union). + +**Phase E — Removal of UXF-bundle-only pointer publishing** ✓ Done (see status table above) + +Per the maintainer call: no backward compat. The UXF-bundle-only pointer code path is removed. Existing callers that produced bundle CIDs to the pointer publisher are routed through the new snapshot builder. + +Phase E completes the cleanup that Phases D.1b + D.2 left behind. After this phase the pointer layer's `fetchAndJoin` callback has exactly one sink for remote pointer state: the per-writer snapshot dispatcher wired through `applySnapshot`. The push side of this cutover already happened in D.1b (flush-scheduler publishes the lean snapshot CID, not the UXF bundle CID); Phase E removes the matching read-side fallback so a wallet whose factory wiring is broken fails *fast* with a clean diagnostic skip reason rather than constructing a layer that silently writes the wrong CAR shape into the bundle index on first remote. + +Concretely Phase E does: +- Promotes `applySnapshot` from optional to required on both `PointerWiringInput` and `buildFetchAndJoin`'s internal deps. The `db: ProfileDatabase` input field is dropped — the wiring helper no longer touches OrbitDB at all because no writes happen on the pointer-read path. The `bundleEncryptionKey` parameter that the legacy bundle-ref encryption used is gone too. +- Removes the entire `// 3b. Legacy fallback — applySnapshot not wired` branch from `buildFetchAndJoin`. That branch previously wrote `{ cid, status: 'active', createdAt }` as an encrypted ref at `tokens.bundle.{cid}` and advanced the local-version cursor; under Item #15 that's structurally wrong because the CID is now the snapshot CID, not a UXF bundle CID. Treating a malformed remote CAR as "legacy bundle CAR" would silently absorb the wrong shape and leave per-writer JOIN unconsumed. +- Adds a new `snapshot_applier_missing` skip reason to `PointerWiringSkipReason`. Both `buildProfilePointerLayer` and `ProfileStorageProvider.tryBuildPointerLayer` check for the applier up front and bail with this reason when wiring is incomplete (typically a test fixture that forgot to set the applier, or a factory bug that constructed the pointer-build before `setSnapshotApplier` ran). The wallet then runs WITHOUT aggregator-pointer recovery — local OrbitDB still works, but cross-device sync via the pointer is paused until the wiring is fixed. +- Cleans up now-unused imports (`encryptProfileValue`, `deriveProfileEncryptionKey`, `buildLocalEntry`, `UxfBundleRef`, `ProfileDatabase`, `BUNDLE_KEY_PREFIX`, `withTimeout`, `ORBITDB_WRITE_TIMEOUT_MS`). + +**Known follow-up (latent bug — RESOLVED in Phase E follow-up):** under D.1b/D.2/E the aggregator pointer now carries a *snapshot* CID, but the lifecycle-manager's periodic-poll path (`runPointerPollOnce`) and cold-start recovery path (`recoverFromAggregatorPointerBestEffort`) previously treated the recovered CID as a UXF *bundle* CID — they called `bundleIndex.addBundle(recoveredCid, …)` directly without first parsing the CAR as a lean snapshot. The result was a stale bundle-index entry pointing at snapshot bytes; the next `load()` would then try to parse the snapshot CAR as a UXF package and fail. The bug was latent because the publish-side reconcile loop (where the `fetchAndJoin` path runs) covered most paths in practice. + +The fix landed in the "Phase E follow-up (`applySnapshotIfWired` host method)" row of the status table above. A new host method `applySnapshotIfWired(cid)` was added symmetric to `publishSnapshotIfWired()`; both the poll and cold-start paths now route the recovered CID through it (fetch + parse + per-writer JOIN dispatch). The legacy direct-`addBundle` path is gone — silently re-writing the snapshot CID as a bundle ref is precisely what the fix removes. No legacy fallback per Phase E: when no applier is wired the lifecycle logs and skips rather than corrupting the bundle index. + +**Phase F — Tombstone GC at snapshot-build time** + +Item #4's tombstone GC currently runs against OrbitDB locally. Under #15: +- Snapshot builder drops tombstones older than `retentionMs` at build time (they're not included in the published snapshot). +- Local OrbitDB cleanup can run separately or as a same-time hook. +- Safety contract unchanged: `retentionMs` must exceed the longest realistic concurrent-replica pre-sync window. Existing 30-day default is conservative. + +**Phase G — Integration tests + crash-recovery scenario** + +- G.1 Two-peer JOIN: A writes OUTBOX entry e_A, snapshots, publishes. B polls, JOINs. Assert e_A is in B's local OUTBOX with A's Lamport. +- G.2 Tombstone-wins-at-JOIN: A tombstones key K at Lamport L_t. B has live entry at K with Lamport L_h < L_t. JOIN preserves the tombstone in B's local state. +- G.3 Race: A and B both flush concurrently for V+1. Aggregator anchors one. Loser re-polls, JOINs, publishes V+2. +- G.4 Crash-recovery (the user-driven scenario): A writes OUTBOX entry then crashes immediately after publish. B detects new version, pulls, JOINs, sees A's OUTBOX entry. B's `SendingRecoveryWorker` can pick it up (same wallet identity = same signing key on both devices). +- G.5 Non-overlapping union: A and B both have OUTBOX entries (different keys). After bidirectional JOIN, both see the full union. + +**Files** (proposed touch list): + +- `profile/profile-export.ts` — extend or sibling for lean v2 builder/parser. +- `profile/outbox-writer.ts`, `profile/sent-ledger-writer.ts`, `profile/disposition-writer.ts` (if exists), `profile/finalization-queue-storage-adapter.ts`, `profile/recipient-context-storage-adapter.ts` (if exists) — add `snapshot()` + `joinSnapshot()`. +- `profile/profile-token-storage/flush-scheduler.ts` — emit lean snapshot instead of UXF bundle. +- `profile/lifecycle-manager.ts` — receive snapshot CID from flusher. +- `profile/pointer-wiring.ts:387-533` — pull-side dispatcher per writer. +- `profile/profile-token-storage-provider.ts` — wire the `notifyProfileDirty()` callbacks from each writer. +- New: `profile/profile-snapshot-merge.ts` — shared CRDT merge helper. +- Tests: `tests/integration/profile/full-profile-sync.test.ts` (new) + per-writer unit tests. + +**Complexity**: Large. Multi-phase (A through G). Each phase can ship independently; Phase A is the prerequisite. Estimated 3-5 PRs. + +**Blast radius**: Very High while the work is in flight (touches the pointer-publish + pull paths that every wallet relies on). Mitigation: feature-flag (`features.fullProfileSnapshotSync`?) gating the new publish/pull behaviour, default-OFF during development, flip to default-ON after Phase A-G land and soak. + +Migration consideration: existing wallets that have published only UXF-bundle pointers need handling — either (a) they re-publish under the new format on first flush after upgrade, OR (b) the cutover is done at a clean release boundary with no in-flight UXF-bundle pointers expected. The maintainer call is (b): no backward compat. Implementation should arrange for the first post-upgrade flush to emit the new format and never read or write the old format. + +**Downstream effects** (forward references): +- Item #2: `'entry-tombstoned-or-missing'` skip becomes rare — OUTBOX entries propagate, so when the verifier needs the entry to transition it's almost always there. +- Item #4: tombstone GC relocates to snapshot-build time (see Phase F). +- Item #6: bundle-bytes always reachable on IPFS pin — the CAR-mode throw at the recovery worker becomes a defensive fallback rather than the common case. +- Item #9: the OrbitDB Hash Log conflict-resolution gap collapses — OrbitDB is no longer the conflict-resolution layer for OUTBOX/SENT. +- Item #10: per-entry-key with Lamport+tombstone is reinforced as the right primitive (it's also the JOIN merge function); vector model loses its appeal. +- Item #14: most of Phase 2 (local-Token correction) is subsumed; Phase 1 (typed throw + new event) still wanted for operator-visible classification but the loser's stuck-`'transferring'` symptom resolves naturally at next sync. + +--- + +### 16. Per-token spent-state rescan (Issue #174 — UXF-TRANSFER-PROTOCOL §12.3.2) — **SHIPPED** + +**Status**: SHIPPED. Worker landed via PR #176 (`feat/spent-state-rescan-worker`).

Structural twin of `nostr-persistence-verifier.ts`. Periodically iterates the active pool (`status === 'confirmed'`), filters out non-eligible candidates (no `sdkData`, OUTBOX-active, per-token interval not yet elapsed, per-token throw-back-off active), calls `oracle.isSpent(currentDestinationStateHash)` with `MAX_CONCURRENT_SPENT_RESCANS = 4` capping concurrent probes. On `isSpent === true`: computes `suspectedSiblingInstance` heuristic by checking the local OUTBOX + SENT ledgers for any record of this `tokenId`, emits `transfer:off-record-spent`, and invokes the injected `transitionToAudit` closure (the disposition-writer route is wired by the bootstrap layer; the worker itself never touches storage directly). +- `types/index.ts` — new `transfer:off-record-spent` event in `SphereEventType` + `SphereEventMap`. Payload: `{ tokenId, detectedAt, suspectedSiblingInstance, coinId, amount }`. +- `modules/payments/PaymentsModule.ts` — `features.spentStateRescan` flag (default-ON post-soak), auto-install + start in `initialize()` mirroring the `nostrPersistenceVerifier` block, `installSpentStateRescanWorker()` install method, `setSpentStateRescanTransitionToAudit()` bootstrap setter, fire-and-forget `stop()` in `destroy()`. +- `docs/uxf/RUNBOOK-SEND-PIPELINE.md` — new "transfer:off-record-spent" operator section + config-reference entry. +- Tests: 17 unit tests in `tests/unit/payments/transfer/spent-state-rescan-worker.test.ts` covering eligibility filter, outcome routing (`true` / `false` / throw), `suspectedSiblingInstance` heuristic branches, concurrency cap, throw-back-off + counter reset, emit failure isolation, transitionToAudit failure isolation, lifecycle (start/stop idempotent, graceful drain). Integration test in `tests/integration/payments/spent-state-rescan.test.ts` covers the canonical sibling-spend vs local-spend scenarios. + +**Relationship to other items**: +- **Companion to Item #14 Phase 1 (reactive)**: Phase 1 (`9b4fae7` / PR #173) added the typed `STATE_ALREADY_SPENT_BY_OTHER` throw + `transfer:double-spend-detected` event that fires at next `send()` attempt — the REACTIVE surface. This item adds the PROACTIVE surface so the UI doesn't keep showing the token as spendable until the user tries to spend it. +- **Companion to Item #15 (profile-pointer rescan)**: Item #15 catches the spend IF the spending device publishes a snapshot to the aggregator and our local pointer-poll picks it up. This worker catches it independently of whether the spender's snapshot has propagated. +- **Distinct from orphan-spending sweeper** (Item #166 P2 #1): that sweeper inspects tokens stuck `'transferring'` with no matching OUTBOX/SENT entry. This worker inspects tokens at `'confirmed'` AND in the active manifest. The two sets are disjoint by the eligibility filter (`'transferring'` tokens are explicitly excluded). + +**Soak-gate follow-up (LANDED)**: `features.spentStateRescan` flipped default-OFF → default-ON. The default-OFF gate was the conservative soak path; with the proactive surface paired to the local-cleanup default closure (archive + tombstone + map delete via `removeToken`), the worst-case for a transient false-positive is a token correctly leaving the spendable pool one rescan cycle before its real spend status would have surfaced reactively. The per-token throw-back-off (3 throws → 30 min cooldown) and concurrency cap (≤4 in flight) bound aggregator load. Wallets that need the reactive-only surface still set `features.spentStateRescan: false` explicitly. + +**Bootstrap-layer follow-up (LANDED in PR #177, branch `feat/spent-state-rescan-bootstrap-wiring`)**: `PaymentsModule.defaultSpentStateTransition` is wired as the default `transitionToAudit` closure. When the worker detects `oracle.isSpent === true`, the closure calls `removeToken()` — archive + tombstone + active-map deletion + persist — so the spent token leaves the spendable pool and the tombstone prevents re-sync resurrection. + +**DispositionWriter wiring follow-up (LANDED in PR #B, branch `feat/spent-state-rescan-disposition-writer`)**: the default closure now ALSO writes a durable `_audit` record (reason `'off-record-spend'`, `auditStatus: 'audit-off-record-spend'`, §5.3 [E] / §5.4) when a `DispositionWriter` is installed via the new `payments.installSpentStateAuditWriter()` slot. Sphere wires the writer from the existing `OrbitDbDispositionStorageAdapter` (the same adapter that backs the operator escape-hatch importer's `_invalid` / `_audit` records) at both primary-address bootstrap and per-address re-init. The writer's `manifestStore` is a throw-on-access stub since only the AUDIT branch fires through this writer. Crash-safety invariant: the AUDIT write only fires AFTER `removeToken()` succeeds — partial application (active token + `_audit` record for the same tokenId) is prevented by an early-return on `removeToken` throw. Writer-side throws are swallowed (warn-log + best-effort next-cycle replay). + +--- + +## Cross-cutting concerns + +### Pointer-layer vs OrbitDB-log layering (architectural clarification — superseded by Item #15) + +> **Direction change (2026-05-18)**: Item #15 (Full Profile State Snapshot Sync) collapses the two-layer model into one. Under #15 the aggregator pointer carries the full profile snapshot (including OUTBOX/SENT/dispositions/etc.) — not just the UXF bundle CID. OrbitDB becomes a local encrypted KV cache; its CRDT-replication features are unused for cross-peer convergence. This section describes the **interim state** that holds until Item #15 lands. + +The profile layer **currently** has TWO distinct distribution mechanisms running in parallel, often confused: + +| Layer | What it carries | Conflict resolution | +|-------|-----------------|---------------------| +| **Aggregator pointer** (today) | The CID of the current UXF token bundle CAR (the `tokens.bundle.*` aggregate). One small commitment per flush, anchored to BFT-backed inclusion proofs. | Unicity aggregator's Sparse Merkle Tree provides total ordering and immutability over the sequence of bundle pointers. Append-only by construction. See `docs/uxf/PROFILE-AGGREGATOR-POINTER-SPEC.md`. | +| **OrbitDB Hash Log** (today) | Per-entry-key writes for OUTBOX/SENT/dispositions/etc. — direct `db.put` calls at keys like `${addr}.outbox.${id}`. NOT bundled into CARs. NOT pointer-published. | OrbitDB's underlying CRDT: LWW lex-sort on entry hashes for concurrent writes to the same key. Lamport stamps + tombstones + refuse-write guard (Issue #166 P1 #2) provide POST-sync safety. | + +**Implication for the writer-layer concerns in this doc (pre-#15)**: items #1–#9 concern OUTBOX/SENT entries that live in the OrbitDB Hash Log layer (not the pointer layer). The pointer mechanism's "Single Irreversible Provable History" guarantee covers WHICH bundle CAR is current — it does NOT cover which value wins for an OUTBOX/SENT slot under concurrent same-key writes from two peers. + +**Implication after Item #15 lands**: the aggregator pointer carries the full profile state. OUTBOX/SENT and every other writer's state is content-addressed inside the snapshot CAR. Conflict resolution moves to snapshot-pull JOIN time, using the same Lamport+tombstone primitives. OrbitDB pubsub remains as a hint channel only. + +**Pubsub clarification**: OrbitDB pubsub IS still wired in `profile/orbitdb-adapter.ts:243-246` (gossipsub is a hard requirement for OrbitDB v3). It is explicitly DEMOTED to a hint channel — `lifecycle-manager.ts:27-49` treats pubsub events as a wake-up signal to poll the aggregator NOW, not as authoritative state. The aggregator pointer is the authority; pubsub is a latency optimisation (collapsing worst-case cross-device sync from ~90 s to ~1-2 s). This stays true under Item #15. + +### Lamport-on-tombstone is incomplete CRDT semantics + +We documented this in the conversation thread that led to Issue #166's close. The refuse-write guard catches the **post-sync** resurrection attempt (replica B observes A's tombstone, attempts write, refused). It does **NOT** catch the pre-sync concurrent race (both replicas write at the same time, OrbitDB picks one via LWW, the loser's signal is lost). Fully closing this requires: + +- In-memory mirror that tracks tombstone Lamports +- Reader-side merge that prefers tombstone over live entry when tombstone.lamport >= live.lamport +- Two-phase tombstone propagation (replicas exchange tombstones before either acts on a key) + +That's a real CRDT implementation, well beyond the scope of #166. Item #9's residual scope (real-OrbitDB-log integration test under live libp2p replication) should at least quantify how often the pre-sync race occurs in practice. **Note**: this concern lives at the OrbitDB Hash Log layer — the aggregator pointer mechanism does NOT address it because OUTBOX/SENT entries are not pointer-published (see "Pointer-layer vs OrbitDB-log layering" above). + +### D0 JOIN Rules 3 & 4 — same-tokenId chain resolution (NEW) + +Surfaced by the 2026-05-18 architectural review of the pointer mechanism. Documented in `docs/uxf/PROFILE-AGGREGATOR-POINTER-D0-JOIN-AUDIT.md`; called out inline at `profile/pointer-wiring.ts:36-40`. + +When two profile flushes from different devices result in CARs that both list the **same `tokenId`** with **different root hashes** (concurrent operations on the same token), the JOIN at `UxfPackage.merge()` resolves the collision by **last-writer-wins on manifest insertion order** rather than by **longest-valid-chain** with proof verification: + +- **Rule 3 (longest-valid-chain)**: when two manifests collide on a tokenId, prefer the chain whose head has the most aggregator-verified transitions behind it. Not implemented for the LWW path. +- **Rule 4 (proof-enrichment)**: lift verified proofs from one merge candidate into the synthesised token-root when only one side carries them. Wired for the proof-verifier path but does not influence Rule 3's gap. + +**Why this is a real concern**: the pointer layer correctly resolves "which CAR is current" — both devices' CARs will be discoverable via their respective historical pointers. But when both CARs are JOINed at load time, conflicting tokenIds are resolved by insertion order (and that order is itself a function of OrbitDB LWW lex-sort timing on the `tokens.bundle.*` ref writes). For non-trivial concurrent operations on the same token from two devices, this can silently discard one device's token history. + +**Why it's not in the numbered items above**: it sits one layer below the OUTBOX/SENT writer concerns and requires its own design effort. It belongs in this cross-cutting section as a forward reference; the actual closure work is tracked in the D0 audit doc. + +**Recommended next action**: open a tracking issue against `pointer-wiring.ts` / `UxfPackage.merge` for the Rules 3 + 4 closure work, with proof-verifier integration to use `OracleProvider.verifyInclusionProof` as the longest-valid-chain arbiter. + +### "Re-publish from where?" — bundle storage + +Items #2 (retention re-publish) and #6 (CAR mode re-publish) both run into the same question: where does the re-publisher get the bundle bytes after the initial publish? + +**Architectural directive (2026-05-18)**: bundle bytes are **NEVER** stored in OUTBOX, SENT, or tombstones. Only the CID is retained. The IPFS pin on our node is the source of truth for bundle bytes; Nostr carries either inline CAR (sender's choice for small bundles) or the CID-by-reference. This rules out the "keep CAR bytes in OUTBOX entry" option from the earlier draft. + +**Forward path** (not yet implemented; tracked here for the future PR): + +- The SENT entry already carries `bundleCid`. The IPFS pin keyed by that CID is the only place the original CAR bytes live. +- A retention-driven re-publish (item #2, post-MVP) materialises a fresh OUTBOX entry from the SENT entry (`id`, `bundleCid`, `tokenIds`, `recipientTransportPubkey`, etc.), status `'sending'`, and lets the SendingRecoveryWorker republish via its existing path. Item #6's `'cid-over-nostr'` arm handles this trivially. +- For `'car-over-nostr'` entries the sender can fetch the CAR bytes from our IPFS pin (using the SENT entry's `bundleCid`) and re-emit inline — OR transparently downgrade to `'cid-over-nostr'` if the receiver accepts either.

Motivation & Goals + +### 1.1 Why the IPNS stopgap is insufficient + +The current Profile cold-start recovery mechanism (`profile/profile-ipns.ts`) publishes a JSON snapshot of active bundle CIDs to IPNS, keyed by a wallet-derived Ed25519 identity (`deriveProfileIpnsIdentity`, HKDF info `"uxf-profile-ed25519-v1"`). It has four structural weaknesses we are no longer willing to ship past the "stopgap" label: + +1. **Eventual consistency.** IPNS records propagate via DHT/PubSub and public gateways. There is no synchronous confirmation that a published record is visible elsewhere. A device that wipes state minutes after a publish may resolve an older record, or none. +2. **No single source of truth for "latest version."** Two devices racing produce two signed records with different `sequence` numbers. IPNS record selection is per-resolver ("highest sequence I happened to see"); neither writer learns it lost. +3. **Routing vs. signing surface area.** IPNS pulls in libp2p key generation, record marshalling, gateway-specific resolve semantics, UnixFS vs. raw-CID mismatches, and a monotonic sequence we must persist. Each is a surface we would rather not own. +4. **Public-key correlation.** The IPNS name is a deterministic function of the wallet private key, and the snapshot body embeds `walletPubkey` verbatim. A passive observer who knows a wallet address can derive a candidate IPNS name and watch its history. + +### 1.2 What the aggregator gives us + +The Unicity aggregator is a Sparse Merkle Tree (SMT) that the ecosystem already runs and already trusts as SSOT for L4 state transitions. It answers `(requestId) → (inclusion | exclusion)` proofs synchronously, and every proof is verifiable against a public root. + +| Property | IPNS stopgap | Aggregator pointer | +|---|---|---| +| SSOT | No (per-gateway resolution) | Yes (SMT root, BFT-ordered) | +| Write confirmation | Best-effort; returns before propagation | Synchronous; aggregator accept ≡ commit | +| Latest-version determination | Highest seq observed by local resolver | Verified exclusion proof at `V+1` ⇒ proof of "no V+1 exists" | +| Conflict detection | None (silent overwrites possible) | Inherent: aggregator rejects duplicate request IDs | +| External identity footprint | Ed25519 peer ID visible; snapshot includes wallet pubkey | Request IDs unlinkable without master key; values XOR-blinded | +| Auditability | Limited (IPNS record history) | Full (verifiable SMT proof chain) | +| Operational cost | libp2p + gateway ops + monotonic seq persistence | Two aggregator commits per publish | +| Dependency graph | libp2p/crypto, libp2p/peer-id, ipns, UnixFS gateway | `state-transition-sdk` (already present in the SDK) | + +Collapsing the recovery mechanism onto infrastructure we already operate strengthens privacy, gains synchronous conflict detection, and removes the libp2p/UnixFS/gateway surface — all in a single move. + +### 1.3 Goals + +- **G1. Synchronous, deterministic "latest version" discovery.** Given only a mnemonic, any device can determine the globally current published pointer without waiting on propagation. +- **G2. Pseudonymity per wallet (not per commit).** A passive aggregator observer cannot link commits to the wallet's *chain pubkey* or *L1 address*, but CAN cluster commits by the stable `signingPubKey` used for pointer authenticators. See §9.2 — this is a conscious downgrade from "unlinkable across commits," documented as known residual risk. +- **G3. Universal CID support.** The scheme accommodates any CID the Profile can produce — CIDv0 (34 bytes), CIDv1+sha256 (~36 bytes), CIDv1+sha512 (~68 bytes), future multihash codecs — up to a 63-byte budget per publish (64-byte envelope minus the 1-byte length prefix; see §4.4). +- **G4. Race-safe multi-device publish.** Two devices publishing concurrently MUST NOT silently overwrite each other. Exactly one wins at any given version; the loser learns synchronously and re-merges. +- **G5. Bounded cold-start cost.** Recovery is `O(log V_true)` aggregator round-trips, not `O(V_true)`. +- **G6. No data loss on partial failures.** The CAR bundle is pinned to IPFS before the pointer is committed. A crashed publish leaves the bundle pinned and recoverable on the next attempt, and retries are **deterministic and idempotent** (§7.2). +- **G7. Mnemonic-only recovery.** The entire recovery path must be re-runnable from a mnemonic alone, with zero prior local state and no prior interaction with any other on-chain object (no token state chain to re-enter, no key rotation path to follow). + +### 1.4 Non-goals + +See §16 for the full list. Explicitly: + +- This design does not attempt to hide aggregator-submission **timing** patterns. +- It does not GC old SMT commitments (append-only by construction). +- It does not add a new key-signing surface beyond what `state-transition-sdk` already provides (§4.6). +- **It does not touch L1 (ALPHA blockchain) at any point.** Pointer commits are entirely an L3 concern. +- **Nostr-delivered events (DMs, NIP-17) are NOT pointer-anchored.** They remain ephemeral transport events outside the Profile-pointer scope. + +--- + +## 2. Design Overview + +This section walks through one publish and one recovery at the narrative level. Formulas are only sketched; the [companion spec](./PROFILE-AGGREGATOR-POINTER-SPEC.md) owns the bit-level details. + +### 2.1 Core idea in one paragraph + +Every time the Profile's OpLog head advances, we assign the new head a monotonically-increasing **version number** `V ∈ ℕ⁺`. We split the new head CID across **two SMT leaves** `A` and `B` at deterministically-derived request IDs `r_A(V)` and `r_B(V)`. Each leaf value is the CID half XOR-blinded with a per-version, per-side key. The aggregator, holding both leaves, does not know they are halves of a CID, nor whose, nor that they are related. The wallet, holding the master key, can (a) compute `(r_A(V), r_B(V))` for any `V`, (b) ask the aggregator for inclusion or exclusion proofs at those request IDs, and (c) decrypt the values once retrieved. + +### 2.2 Why two plain leaves, and not a tokenized pointer? + +An attractive alternative is to represent the pointer as a **tokenized L3 token** whose state transitions point to successive OpLog CIDs. This was explicitly considered and **rejected**. See §14 for the full comparison; the load-bearing reason is G7 (mnemonic-only recovery): + +> A tokenized token's state data cannot serve as a pointer recoverable from *mnemonic alone, with no prior setup*. To re-enter a token state chain, the wallet must already know the token's current state hash (or some anchor that locates the chain). On a fresh device with only a mnemonic, that anchor does not exist. The two-leaf plain-commitment design re-derives `r_A(V)`, `r_B(V)` purely from the master key and a version integer — no prior anchor needed. + +### 2.3 Why two leaves? The CID length problem + +Aggregator leaves hold 32-byte values. CIDs are variable-length: + +| CID shape | Typical length | +|---|---| +| CIDv0 (bare sha256 multihash) | 34 bytes | +| CIDv1 + dag-cbor + sha256 | ~36 bytes | +| CIDv1 + dag-pb + sha256 | ~36 bytes | +| CIDv1 + raw + sha256 | ~36 bytes | +| CIDv1 + dag-cbor + sha512 | ~68 bytes (forward-compat; too large — see §4.4) | + +Splitting across two leaves gives us **64 bytes of envelope**, which covers every CID shape we reasonably expect today. The spec fixes a 1-byte length prefix inside the envelope (§4.4), leaving **63 bytes of usable CID**. CIDs longer than 63 bytes are rejected at publish time (`AGGREGATOR_POINTER_CID_TOO_LARGE`); a three-leaf extension is documented as future work in the spec. + +### 2.4 Why XOR-blind the values? + +The aggregator operator (and any passive observer with database access) sees leaf values in the clear. Writing CID halves directly would let operators: + +- detect pairs of leaves whose concatenation parses as a valid CID prefix, +- fingerprint "this request ID family" as belonging to the Profile-pointer product, +- test which gateway serves which CAR bundle and cross-correlate with wallet activity. + +XOR-blinding with `xorKey_{side, V} = SHA-256(xorSeed || [side] || be32(V) || bytes_of("xor"))` (bare SHA-256 via DataHasher; see §4.3) gives each leaf the distribution of uniformly-random 32-byte strings. Without `xorSeed`, an observer cannot distinguish a blinded leaf from any other 32-byte random payload the aggregator holds. + +### 2.5 Why exclusion proofs as the "end" signal? + +The aggregator supports both **inclusion proofs** ("the leaf at `r` has value `v`, here's a Merkle path") and **exclusion proofs** ("no leaf at `r`, here's a Merkle path proving absence"). Both are first-class cryptographic objects, verifiable via the SDK's `InclusionProof.verify(trustBase, requestId)`. + +The "latest published version is `V`" claim is therefore expressible as a conjunction of four verifiable proofs: + +``` + inclusion(r_A(V)) ∧ inclusion(r_B(V)) ∧ exclusion(r_A(V+1)) ∧ exclusion(r_B(V+1)) +``` + +Any party holding `pointerSecret` can compute the four request IDs, fetch the four proofs, and verify them locally against the aggregator's published root. This is stronger than IPNS's "highest sequence I happened to see" — it is a cryptographically verifiable statement about the entire published history. + +### 2.6 One-sentence publish flow + +> *Compute next version `V`; persist `(V, H(cidBytes))` to local crash-safety storage (§7.2); pin the bundle CAR to IPFS; derive `r_A(V)`, `r_B(V)` via the SDK's `RequestId.createFromImprint` formula (§4.3) and derive `xorKey_{A,V}`, `xorKey_{B,V}` as bare SHA-256 over `xorSeed || [side] || be32(V) || "xor"`; XOR-blind the CID halves (with deterministic padding — §4.5); sign two aggregator commitments via the SDK's `Authenticator.create(signingService, transactionHash, stateHash)`; submit both in parallel via the aggregator client; confirm both succeeded via `InclusionProof.verify(trustBase, requestId)`.* + +### 2.7 One-sentence recovery flow + +> *From the mnemonic, derive `pointerSecret` via HKDF; run exponential-probe + binary-search against `r_A(V)` and `r_B(V)` at every probed version (§10); upon convergence, fetch inclusion proofs at `(r_A(V), r_B(V))` and exclusion proofs at `(r_A(V+1), r_B(V+1))`, verify all four via `InclusionProof.verify`, XOR-decode the blinded halves to recover the CID; fetch the CAR from IPFS; seed OrbitDB; resume normal load.* + +--- + +## 3. Component Topology + +This scheme slots into the existing Profile stack as a **new publish/resolve channel** inside `ProfileTokenStorageProvider`, replacing the IPNS helpers.

The imprint is `[algo_hi, algo_lo] ‖ digest` (34 bytes for SHA-256 with `algo = [0x00, 0x00]`). Any reader tempted to short-circuit this as `H(pubkey ‖ digest)` is wrong — **use `RequestId.createFromImprint` and do not re-implement the hash by hand.** + +### 4.4 Value encoding and length hint + +**Decision (reviewer C-3):** the length hint is encoded as a **1-byte length prefix at offset 0 of the first leaf's plaintext**. This is Option (a) from the prior draft. + +``` + Plaintext layout (before XOR): + bytes [0 .. 63] + ┌────┬──────────────────────────────────────────────────────────────┐ + │ L │ cid[0 ..

The decoder reads byte 0, knows the CID length, and trims. +- The L byte is XOR-blinded by the one-time pad and therefore invisible to external observers. +- Avoids dependency on a CID-parser-that-tolerates-trailing-random-bytes (an error-prone feature). +- Maximum usable CID length is `64 − 1 = 63` bytes. + +CIDs longer than 63 bytes are rejected at publish time with `AGGREGATOR_POINTER_CID_TOO_LARGE` (spec §12). A three-leaf extension is future work. + +### 4.5 Deterministic padding (reviewer W-5) + +Padding bytes are NOT generated from a CSPRNG. They are derived deterministically, **once per version and shared across both sides** (not per-side): + +``` +cidLen = len(cidBytes) (1 ≤ cidLen ≤ 63) +padLength = 63 − cidLen (always ≥ 0) +paddingBytes_v = HKDF-Expand(padSeed, info = be32(V) || bytes_of("pad"), L = padLength) +``` + +The single `paddingBytes_v` buffer occupies plaintext offsets `[1 + cidLen .. 64)` of the 64-byte envelope (spanning side A and side B, see §4.4 layout); there is no per-side padding. + +Benefits: + +- **Crash-retry is byte-identical** → idempotent aggregator re-submission (W-5, C-4). +- **No CSPRNG dependency** at publish time. +- Privacy-neutral: `padSeed` is secret-derived; the ciphertext is still uniformly-random-looking to any observer without `pointerSecret`. + +Under the random-oracle model, `paddingBytes_v` is independent of `xorKey_{side, V}` and `stateHashDigest_{side, V}` because padding derives from `padSeed` under a `"pad"` suffix, while the `xorKey` and `stateHashDigest` are bare SHA-256 over `xorSeed`-prefixed preimages under `"xor"` and `"state"` suffixes respectively (see §4.3). Domain separation via distinct seeds and distinct suffixes makes the three outputs computationally independent. + +### 4.6 SDK primitives used (reviewer N-4) + +Every cryptographic or aggregator-facing operation in this scheme maps onto an existing `state-transition-sdk` primitive. Implementors MUST use the SDK calls below rather than re-implementing the formulas: + +| Operation | SDK call | +|---|---| +| HKDF-SHA256 from wallet secret | `@noble/hashes/hkdf` — already used in `impl/shared/ipfs/ipns-key-derivation.ts`. Non-SDK dependency, permitted. | +| SHA-256 digest | `new DataHasher(HashAlgorithm.SHA256).update(bytes).digest()` — returns a `DataHash` | +| Derive signing keypair from seed | `SigningService.createFromSecret(signingSeed)` — returns a service whose `publicKey` is the 33-byte compressed secp256k1 pubkey. **Rationale (load-bearing): the `createFromSecret` form SHA-256-hashes its input before using it as the secp256k1 private-key scalar. This provides free rejection-sampling-equivalent uniformity across the curve's group order and is required for interoperability between implementations. The raw constructor `new SigningService(seed)` would produce a DIFFERENT `signingPubKey` for the same seed and MUST NOT be used.** | +| Compute request ID | `RequestId.createFromImprint(signingPubKey, stateHash.imprint)` | +| Build authenticator | `Authenticator.create(signingService, transactionHash, stateHash)` | +| Build submission | `SubmitCommitmentRequest` (fields: `requestId`, `transactionHash`, `authenticator`) | +| Submit to aggregator | `aggregatorClient.submitCommitment(request)` | +| Verify inclusion/exclusion proof | `InclusionProof.verify(trustBase, requestId)` | +| Trust-base anchor | `RootTrustBase` (see §6.5 for TOFU / cross-check strategy) | + +**Non-SDK primitives allowed:** HKDF-SHA256 (`@noble/hashes/hkdf`) and bytewise XOR. **No CSPRNG is used** — padding is deterministic (§4.5). + +**Banned primitives:** + +- **Ed25519 is banned.** The aggregator accepts secp256k1 authenticators only. The signing key is secp256k1, derived via HKDF-Expand from `signingSeed` (§4.1) and handed to the SDK's secp256k1 SigningService. Any reference to Ed25519 in the current codebase (`deriveProfileIpnsIdentity` in `profile/profile-ipns.ts`) is deleted as part of this migration. +- Custom hash constructions, custom signature schemes, custom SMT proof verifiers. + +--- + +## 5. Versioning Semantics + +### 5.1 What counts as a "new version" + +A new version is minted every time the Profile's OpLog head advances to a new CID that the wallet wants to anchor. In the current Profile model, that corresponds to every `flushToIpfs()` that produces a new bundle CID. Triggering events: + +- Token arrivals / spends. +- DM arrivals. +- Nametag registrations. +- Profile schema changes. +- Consolidation rewrites (PROFILE-ARCHITECTURE §2.3). + +### 5.2 The version counter + +- **Scope: per wallet, not per address or per device** (reviewer N-10). All HD addresses under one mnemonic share one OpLog and therefore one pointer chain. Matches PROFILE-ARCHITECTURE §2.1 global-keys model. +- Domain: `ℕ⁺` (1, 2, 3, ...). `V = 0` means "no version has ever been published" and manifests as a verified exclusion proof at `r_A(1)`. +- Local storage: cached at `profile.pointer.version`. The local value is an optimization; authoritative latest-version is rediscovered from the aggregator on conflict or cold start. +- **Multi-network scoping (reviewer N-9):** testnet vs mainnet pointer chains are disjoint because each aggregator runs its own SMT. Key derivations are identical across networks; only the aggregator URL differs. + +### 5.3 The monotonicity invariant + +> **Invariant I-1.** If `V` is the highest version the aggregator has ever committed for this wallet, then for every `V' ≤ V`, at least one of `r_A(V')`, `r_B(V')` is included. Simultaneous exclusion of both sides at any `V' ≤ V` is impossible. The "include/exclude boundary" on either side is therefore well-defined for binary search. + +### 5.4 Retry on conflict (preview) + +If the wallet attempts to publish at `V_next = V_local + 1` and the aggregator rejects one or both submissions as "request ID already taken," the wallet discovers the true `V_true`, merges the winner's CID, and retries at `V_true + 1`. See §8 for details. + +### 5.5 Aggregator reset (reviewer N-8) + +If the aggregator SMT is reset (e.g., testnet wipe), the wallet's `localVersion` is stale. On first publish post-reset, submission at `localVersion + 1` may succeed because the fresh aggregator has no entry — but the wallet's view of "latest CID" from IPFS may still be valid, and the merge path still works. An explicit `Profile.resetPointerVersion()` hook is provided for manual migration. + +--- + +## 6. Recovery Flow + +### 6.1 When it runs + +Recovery is triggered in `ProfileTokenStorageProvider::initialize` when the local OrbitDB has zero bundle keys. Classic "fresh device after mnemonic re-import." It also runs as part of conflict handling when a publish is rejected (§8). + +### 6.2 End-to-end sequence (ASCII) + +``` + Wallet Aggregator IPFS + ────── ────────── ──── + │ (boot from mnemonic) │ │ + │ │ │ + │ derive mk, pointerSecret, │ │ + │ signingSeed, xorSeed, │ │ + │ padSeed (§4.1) │ │ + │ │ │ + │ obtain RootTrustBase │ │ + │ (TOFU or pinned, §6.5) │ │ + │ │ │ + │ ─── probe r_A(V_init) ───────► │ + │ ─── probe r_B(V_init) ───────► (parallel, same V) │ + │ ◄── inclusion/exclusion ─────── │ + │ ◄── inclusion/exclusion ─────── │ + │ (exponential phase, §10) │ │ + │ │ │ + │ ...binary search... │ │ + │ │ │ + │ (converged: V_true = 833) │ │ + │ │ │ + │ ─── getProof r_A(833) ──────► │ + │ ─── getProof r_B(833) ──────► (parallel) │ + │ ─── getProof r_A(834) ──────► │ + │ ─── getProof r_B(834) ──────► │ + │ ◄── inclusion(ctA) ──────────── │ + │ ◄── inclusion(ctB) ──────────── │ + │ ◄── exclusion ──────────────── │ + │ ◄── exclusion ──────────────── │ + │ │ │ + │ InclusionProof.verify(trustBase, requestId) × 4 │ + │ (reject recovery if ANY fails) │ + │ │ │ + │ XOR-decrypt → plainA || plainB │ + │ L = plainA[0] │ + │ cid = plainA[1..L+1] || plainB[...] (trim padding) │ + │ validate CID decode │ + │ │ │ + │ ──── fetch CAR(cid) ─────────────────────────────────────►│ + │ ◄─────────────────────────────────────── CAR bytes ────────│ + │ │ │ + │ db.put('tokens.bundle.' + cid, { status: 'active', ... }) │ + │ emit pointer:recovered { version, bundleCount } │ + │ │ │ + │ (normal PaymentsModule load resumes; OrbitDB replication │ + │ catches up in the background with any newer bundles) │ +``` + +### 6.3 Step-by-step narrative + +1. **Bootstrap secrets.** From the mnemonic, derive `mk`; derive `pointerSecret`, `signingSeed`, `xorSeed`, `padSeed` via HKDF (§4.1). +2. **Obtain the trust base.** Load `RootTrustBase` per §6.5. If unavailable, abort recovery with a diagnostic — we will not accept unverified aggregator claims. +3. **Probe reachability.** A single probe at `V = 1` tells us whether the aggregator is reachable AND whether any pointer exists. If the aggregator is unreachable, enter the blocked state (§6.7). +4. **Discover `V_true`.** Run exponential + binary search (§10). **Probe both `r_A(V)` and `r_B(V)` at every probed version** (reviewer C-3). Seed the search with `max(localVersion, 0)` if a stale local counter is available (reviewer W-7). +5. **Fetch and verify.** Request inclusion proofs at `(r_A(V), r_B(V))` and exclusion proofs at `(r_A(V+1), r_B(V+1))`. Verify each via `InclusionProof.verify(trustBase, requestId)`. If any verification fails, abort with `AGGREGATOR_POINTER_UNTRUSTED_PROOF`. +6. **Decrypt.** Compute `xorKey(A, V)` and `xorKey(B, V)`. XOR each leaf's ciphertext digest to recover the plaintext halves. +7. **Reconstruct the CID.** Read `L = plainA[0]`, assemble `cid = (plainA[1..32] ‖ plainB[0..])[0..L]`, attempt CID decode (codec, multihash check). On failure, emit `AGGREGATOR_POINTER_CORRUPT` and abort — see §12.4. +8. **Fetch the CAR.** Via existing `fetchFromIpfs(cid)`. If unavailable on all gateways, log and proceed with empty state (same fallback as IPNS today). +9. **Seed OrbitDB.** Insert `tokens.bundle.{cid}` with `status: 'active'`. Idempotent under OrbitDB LWW KV. +10. **Hand off.** `PaymentsModule.load()` runs its normal multi-bundle merge. + +### 6.4 Pseudocode (minimal) + +The narrative below mirrors the three-phase discovery algorithm in spec §8.2. It deliberately does NOT require a verified exclusion at `V+1` — that v3.2 invariant was superseded by valid-version continuity (§9.8 / spec §10.3), which accepts corrupt-included residue above the latest valid version rather than aborting on it. + +``` +fn recover(mk, trustBase): + pointerSecret, signingSeed, xorSeed, padSeed := deriveKeys(mk) + signingService := SigningService.createFromSecret(signingSeed) + signingPubKey := signingService.publicKey + + // 1. Seed lo from localVersion (§10.5 / spec §8.2). + lo := max(0, localVersion) + hi := max(DISCOVERY_INITIAL_VERSION, lo + 1) + + // 2. Phase 1 — exponential expansion using inclusion-only probe(). + // probe(v) returns true iff BOTH SIDE_A AND SIDE_B have verified + // inclusion proofs at v (spec §8.1 — probe-predicate is AND over + // sides; the OR variant discussed in spec §8.1 covers a narrow + // partial-publish window and is not used for the global + // exponential step). Doubling continues until probe(hi) is false + // or DISCOVERY_HARD_CEILING is reached. + while probe(hi): + lo := hi + hi := hi * 2 + + // 3. Phase 2 — binary search on (lo, hi) to converge on V_included: + // the latest version with verified inclusion on both sides. + V_included := binarySearch(lo, hi, probe) + if V_included == 0: + return EmptyProfile + + // 4. Phase 3 — walk-back through SEMANTICALLY_INVALID versions. + // A version is SEMANTICALLY_INVALID if its XOR-decoded payload is + // malformed, its CID does not parse, or its CAR fails to + // deserialize — i.e., it is corrupt in a deterministic, + // locally-verifiable way (spec §10.3).

Recover payload at V_valid, verify four proofs, decrypt, fetch + // CAR (with MAX_CAR_BYTES and progress-rate enforcement — spec + // §8.5), seed OrbitDB, emit pointer:recovered { version: V_valid }. + return recoverAt(V_valid, pointerSecret, signingPubKey, xorSeed, trustBase) +``` + +The difference from the v3.2 text: the old §6.4 required verified *exclusion* at `V+1` as a termination condition. That requirement is removed. Discovery now returns the latest VALID version; the aggregator may hold corrupt-but-included entries at higher version numbers and discovery skips them. See §9.8 for the narrative of why and spec §10.3 / §8.2 Phase 3 for the canonical rule. + +### 6.5 Trust base — embedded anchor model (v3.4) + +Every proof returned by the aggregator is verified locally via `InclusionProof.verify(trustBase, requestId)` against a `RootTrustBase`. In v1 Sphere, that trust base is shipped inside the SDK bundle and shared with L4. + +**Embedded `RootTrustBase` (v3.4 — the authoritative rule).** The SDK ships `RootTrustBase` statically under `assets/trustbase/.ts` and loads it via `impl/shared/trustbase-loader.ts`. This is the SAME instance L4 / `PaymentsModule` already consumes through `OracleProvider` in the current Sphere deployment. The pointer layer MUST consume that same instance (spec §8.4, §8.4.2). Fresh devices with only a mnemonic load the bundled trust base at init time — there is no runtime fetch of trust-base bytes, therefore no "fresh boot" TOFU dilemma. + +- **Single canonical source of truth.** L4 already decided it — the pointer layer adopts the same decision. Asymmetric trust surfaces (pointer layer trusting a different `RootTrustBase` from L4) are explicitly prohibited. +- **Rotation.** `RootTrustBase` rotation is driven by SDK releases: when BFT validators rotate epochs, Sphere ships a new build whose bundled trust base carries the new epoch. Runtime detection is via `NOT_AUTHENTICATED` + epoch mismatch surfacing as `AGGREGATOR_POINTER_TRUST_BASE_STALE` (spec §8.4.1); the wallet does NOT attempt a runtime refetch. +- **Residual risk = bundle supply chain.** The attacker's only path to a forged trust base is compromising the SDK release itself. This is a known v1 trade-off, closed in v2 by L1-alpha-anchored trust-base fingerprinting (§12). + +**Multi-mirror TOFU deferred to v2 (retained as narrative for reviewers).** Earlier revisions required a mandatory multi-mirror TOFU cross-check (≥ 2 independently-addressed aggregator mirrors returning byte-identical trust bases) on first-boot recovery. v3.4 deletes that rule because the deployed Sphere topology is a single aggregator (`aggregator.unicity.network` or `goggregator-test.unicity.network`) and a single IPFS node (`ipfs.unicity.network`), and the trust base is already bundled rather than runtime-fetched. Multi-mirror TOFU re-emerges as a meaningful defense only alongside v2 runtime-fetched trust-base infrastructure — see §12 and spec §11.13 item (i). The v2 plan pairs runtime fetch with L1-alpha anchoring and re-introduces multi-mirror cross-check on top of that foundation. + +### 6.6 Fresh-wallet / no-pointer-yet case + +A wallet that has never published (new mnemonic, freshly imported, no activity) will receive a verified exclusion proof at `r_A(1)` and `r_B(1)` from the aggregator. Recovery reports `V = 0`, no CAR is fetched, OrbitDB remains empty, and the wallet is ready to publish its first version. + +### 6.7 Aggregator-unreachable recovery path (reviewer C-5) + +**Previous behavior (rejected):** log a warning and proceed with empty state, letting the next publish act as if `V = 1` were the first version. This is unsafe — if the aggregator was merely unreachable, the next publish overwrites a legitimate remote history at `V = 1`. + +**Mandated behavior (narrative; spec §10.2 owns the byte-level state machine):** + +The wallet maintains a per-wallet **persistent** BLOCKED flag — the canonical storage key is `BLOCKED_FLAG_KEY = "profile.pointer.blocked." + hex(signingPubKey)` (spec §10.2.1). The flag survives process restarts. An absent key is equivalent to `false`. When BLOCKED is set, `publishAggregatorPointerBestEffort` refuses to run and the publish attempt surfaces `AGGREGATOR_POINTER_UNREACHABLE_RECOVERY_BLOCKED`. The state flips as follows: + +- **SET BLOCKED** when ALL of these hold (spec §10.2.2 enumerates four explicit conditions; arch presents them in the same order — see spec for the normative list): + - (i) `initialize()` — or any subsequent reconciliation pass — has actually attempted to reach the aggregator for recovery (the precondition that a probe was even issued); + - (ii) that attempt hit a **categorical** transport error: a true network timeout, DNS failure, TLS handshake failure, or socket-refused. **Note (v3.3 clarification):** `NOT_AUTHENTICATED` from `InclusionProof.verify` is NOT categorical — it is a trust-base-stale signal that triggers trust-base refresh (spec §8.4.1) followed by a single retry; only if the retry remains categorical does it count toward condition (ii). Similarly, transient 5xx responses MUST NOT count on first occurrence. + - (iii) the local OpLog contains at least one **user-originated** write (see next bullet, and spec §10.2.3 for the full `originated` tag definition and migration notes for PaymentsModule, AccountingModule, SwapModule, CommunicationsModule, and profile-token-storage-provider); + - (iv) at least one retry with exponential backoff has already been attempted AND failed (to avoid flapping on single transient failures). + + Re-SET on the same category of error during a subsequent publish. The v3.2-added fresh-install cold-start rule is preserved: + - (v) Fresh-install cold-start recovery produced a `SEMANTICALLY_INVALID` payload at the latest-included version that cannot be walked back because `localVersion == 0` (spec §10.2.6 — retained as a safety net, now narrow in scope because discovery walks back past such residue when any lower-version valid version exists). +- **User-originated write.** An OpLog entry is *user-originated* iff its `originated` metadata tag equals `'user'` (spec §10.2.3). Writers MUST stamp each entry with one of: + - `'user'` — deliberate user action (token send/receive, nametag register, DM send, invoice, swap) + - `'system'` — SDK-internal bookkeeping (session receipt, last-opened timestamp) + - `'replicated'` — arrived via OrbitDB gossipsub or Nostr ingest + + Only `'user'` entries satisfy SET condition (iii) of §6.7. Recipients semantically re-validate the tag — entries of known-user-action types MUST have `'user'` regardless of the stamped value (spec §10.2.3 closes the tag-forgery bypass via `SECURITY_ORIGIN_MISMATCH`). This replaces the r3 `signedBy == localSigningPubKey` heuristic, which was ambiguous in both directions (a signed session-receipt spuriously satisfied it; an unsigned "touch" write slipped past). +- **CLEAR BLOCKED** only after EITHER (spec §10.2.4): + - (a) a trustlessly-verified **exclusion** proof at `requestId_{A,1}` AND `requestId_{B,1}` (applies only when `localVersion == 0`), OR + - (b) a successful `recoverLatest()` yielding `V_true > 0` AND the CAR is fetched from IPFS AND the remote bundle is merged into the local OpLog. + Reachability-only probes, UI "dismiss" actions, and user-preference toggles MUST NOT clear BLOCKED. +- **User override protocol** (optional; spec §10.2.5). For permanent-outage scenarios (regional outage, deprecated testnet, air-gapped recovery), implementations MAY expose an opt-in, per-call, capability-gated override that bypasses BLOCKED. Each use emits `pointer:publish_override_used { version, reason }` telemetry. v1 implementations MAY omit the override entirely. + +This preserves user-visible write semantics (the wallet appears to function, local OpLog fills) while guaranteeing that the next on-aggregator commit cannot silently overwrite a remote history. + +**Fresh-install corrupt-payload at cold start (v3.2).** The r3.1 "BLOCKED on corrupt-payload when `localVersion == 0`" rule is **removed**. Corrupt versions are now treated as semantically ignored residue in the aggregator SMT; discovery walks back past them to the latest valid version rather than blocking publish. The MITM concern r3.1 cited is absorbed into the broader valid-version-continuity model (§9.8) together with the shared embedded `RootTrustBase` (§6.5), and the corrupt-streak bail-out (spec §10.8).

If two different CIDs `cid1` and `cid2` are XOR-encoded under the same `(V, side)` key, an observer who sees both ciphertexts can compute `cipher1 ⊕ cipher2 = plain1 ⊕ plain2`, which leaks both plaintexts under standard XOR cryptanalysis. + +**How the vulnerability arises.** A crash between "compute payload for CID₁" and "submit" followed by a restart where the wallet has advanced OpLog state (now reflecting CID₂) and re-uses `V` would produce a second submission at the same `(V, side)` with a different plaintext. The aggregator rejects the second request (duplicate requestId) — but if the first submission had partially leaked (e.g., side A landed, side B didn't, and the first run's side B was never submitted), a passive observer could be in possession of partial ciphertexts for both plaintexts. + +**Mitigation — the `pending_version` marker (narrative; spec §7.1 owns the byte-level discipline).** Before computing payloads for a given `V`, the publisher MUST persist a `(v, cidHash)` record — spec §7.1 calls this the `pending_version` marker — keyed under `PENDING_VERSION_KEY = "profile.pointer.pending_version." + hex(signingPubKey)` (per-wallet scoping). The critical section (read marker → write marker → submit → clear marker) runs under the per-wallet exclusive mutex `MUTEX_KEY = "profile.pointer.publish.lock"` (spec §7.1.1). The marker write MUST be **durable** before any downstream derivation runs — IndexedDB backends await `transaction.oncomplete`; file-based backends issue an explicit `fsync`; storage backends that cannot guarantee durability MUST refuse to initialize the pointer layer (spec §7.1.3). `cidHash` is a full-length `SHA-256(cidBytes)` (32 bytes) — not truncated. On restart: + +- If no marker exists, proceed normally. +- If a marker `(v, cidHash_prev)` exists AND the current `SHA-256(cidBytes)` matches `cidHash_prev`, this is a legitimate retry of the *same* CID at the *same* `v` — retry with byte-identical payloads (safe; `requestId`s are deterministic, aggregator treats duplicate as idempotent-accept). +- If a marker exists AND the hashes differ (a crashed publisher is re-entering with a DIFFERENT CID), the publisher MUST NOT reuse `v`. The rollback-safe rule (spec §7.1): treat any `previousEntry.v >= v` as a signal to advance, setting `v = max(v, previousEntry.v) + 1`, persisting a fresh marker at the new `v`, and submitting there. The stale marker is cleared only after the new submission resolves. + +The marker is cleared only after a successful publish (both sides committed, `localVersion` persisted) or after the publisher definitively abandons the version (e.g., a non-retryable `REQUEST_ID_MISMATCH`). See spec §7.1.5 and §7.1.6 for exhaustive transition rules. + +### 7.3 Publish outcome matrix and retry (reviewer W-3; v3.3 expansion) + +#### 7.3.1 Outcome matrix (narrative) + +Spec §7.3 owns the normative outcome matrix — one row per observable combination of side-A and side-B submission results. The v3.3 pass expanded the rows to cover HTTP status codes, JSON-RPC protocol errors, malformed responses, and the `REJECTED` burn-version rule. At the architectural level, every publish attempt resolves into one of these categories: + +- **SUCCESS / SUCCESS.** Both sides committed cleanly. Persist `localVersion = V_next`, clear the `pending_version` marker, emit `pointer:publish_completed`. Happy path. +- **REQUEST_ID_EXISTS on both sides, marker matches.** Our own prior attempt crashed between aggregator-accept and `localVersion` persistence. Treated as **idempotent replay success**: persist `localVersion = V_next`, clear the marker, emit `pointer:publish_completed`. §9 reconciliation is NOT invoked. +- **REQUEST_ID_EXISTS on both sides, marker missing or `cidHash` mismatch.** Genuine conflict — another device published `V_next` first. Invoke §9 reconciliation; retry at `max(V_valid, V_included) + 1` (see §9.2 below). +- **AUTHENTICATOR_VERIFICATION_FAILED or REQUEST_ID_MISMATCH on either side (v3.3 change).** The authenticator the aggregator received was malformed relative to the request ID — the submission is unambiguously our own doing but is unrecoverable at `V_next`. Arch-level rule: **burn `V_next` by persisting `localVersion = V_next`** before clearing the marker, then raise `AGGREGATOR_POINTER_REJECTED`. This prevents any subsequent attempt from re-deriving the same `(xorKey, V, side)` OTP against a different plaintext (see spec §7.3 row + §11 bullet 2 on OTP discipline). v3.2 cleared the marker without advancing `localVersion`, which permitted OTP reuse on retry — a token-loss path. +- **Transient HTTP errors (5xx, 429, JSON-RPC `-32006`, 503 with `Retry-After`).** Retry with backoff. If `Retry-After` is present, honor the indicated delay (and do NOT charge it to `PUBLISH_RETRY_BUDGET`). Otherwise apply jittered exponential backoff up to `PUBLISH_RETRY_BUDGET`. +- **Permanent HTTP errors (4xx other than 429).** Non-retryable. Raise `AGGREGATOR_POINTER_AGGREGATOR_REJECTED`; do not retry; surface to the caller. Malformed JSON and unknown enum values land in this bucket (spec W3). +- **Network errors (true transport failure — timeout, DNS, TLS).** Categorical per §10.2.2 condition (ii). A single transient failure retries; sustained categorical failure across the retry budget is the signal that promotes the wallet into BLOCKED (see §6.7). + +#### 7.3.2 Retry backoff with jitter + +Deterministic payloads allow idempotent retry. Backoff must include jitter to prevent synchronous retry storms across multiple devices: + +``` +backoff(n) = BASE_MS × 2^n × uniform(0.5, 1.5) +``` + +Without jitter, multi-device contention degenerates to synchronous retries at `T`, `2T`, `4T`, `...`, re-colliding at every step. The ×0.5..×1.5 jitter range de-synchronizes retries while keeping the base exponential growth. Concrete values live in the spec (`PUBLISH_BACKOFF_BASE_MS`, `PUBLISH_BACKOFF_MAX_MS`, `PUBLISH_RETRY_BUDGET`). `Retry-After`-honored waits do NOT consume retry budget. + +### 7.4 Events emitted (reviewer W-9) + +To match existing SDK patterns (`transfer:confirmed`, `nametag:registered`): + +| Event | Payload | +|---|---| +| `pointer:publish_started` | `{ version }` | +| `pointer:publish_completed` | `{ version }` | +| `pointer:publish_failed` | `{ version, code }` | +| `pointer:recovered` | `{ version, bundleCount }` | +| `pointer:publish_blocked` | `{ reason }` (aggregator unreachable; write staged) | +| `pointer:publish_override_used` | `{ version, reason }` (emitted only if the user-override path §6.7 / spec §10.2.5 is invoked) | + +--- + +## 8.

Both are up-to-date at `V = 41`: + +- **Laptop flushes first.** Computes `V_next = 42`. Submits `r_A(42)`, `r_B(42)`. Aggregator accepts both. Laptop's local `profile.pointer.version = 42`. +- **Phone flushes, unaware of 42.** Computes `V_next = 42`. Submits `r_A(42)`. Aggregator rejects. + +### 8.2 Phone's conflict-handling path + +1. Catch the aggregator rejection on `r_A(42)` or `r_B(42)`. +2. Do NOT resubmit at `V = 42` — that request ID is burned forever (append-only SMT). +3. Run the recovery flow (§6). Discovery returns BOTH `V_valid` (latest valid version usable for payload recovery) AND `V_included` (latest-included version, which MAY be corrupt residue above `V_valid`). See spec §8.2 and §9.2. +4. Verify the discovered CID at `V_valid` is the laptop's bundle CID. The phone may already have it locally via OrbitDB gossipsub; if not, fetch CAR and seed OrbitDB. +5. Merge into the phone's in-memory inventory (standard multi-bundle merge). This produces a new combined CID `C_merged`. +6. Bump to `V_next = max(V_valid, V_included) + 1` (v3.3 — spec §9.2). Persist `(V_next, H(C_merged))`. Submit `r_A(V_next)`, `r_B(V_next)`. **Why `max` instead of just `V_valid + 1`:** corrupt-but-included residue between `V_valid` and `V_included` burns those request IDs; targeting `V_valid + 1` would immediately collide with them and deadlock the publisher forever. The v3.2 text said "bump to `V_true + 1`" assuming `V_true = V_included = V_valid`; v3.3 disambiguates for the case where corrupt residue exists. +7. If `V_next` is also contested, the loop repeats. Termination is guaranteed under any finite number of concurrent writers, because each loss strictly increases the version floor. + +### 8.3 Why this is stronger than last-write-wins + +IPNS: both devices can publish `seq=N+1`; resolvers may return either; no synchronous loser signal; silent divergence for hours. + +Aggregator: both devices see the same SMT root; the loser's submission is **synchronously rejected** with a verifiable error; the loser **must** reconcile before progressing; there is no silent-divergence window. + +### 8.4 Single-device sequential publish + +Counter increments locally and every submission succeeds on first try. No extra round trips. + +### 8.5 Many-device burst publish + +If `k` devices race at `V`, exactly one wins `V+1`; the other `k−1` discover it and race at `V+2`.

Over time, an aggregator operator sees N commits from the same signer and can count them, infer cadence, and correlate with timing windows of other wallet activity (IP correlation, concurrent L3 submissions). +- **Infer version count** by observing probe patterns during discovery. +- **Infer activity cadence** from publish frequency. + +**Known leakage, no mitigation in this PR (reviewer N-6).** Aggregator operators, passive network observers, and IP-correlation attackers can cluster all commits by the same `signingPubKey`. This is the cost of keeping one stable signing identity per wallet for this iteration. Documented as `Q-7` in §16. + +**Future mitigation (deferred, per user direction):** per-version throwaway signing keys. Each commit uses a freshly-derived secp256k1 signing key, unlinkable across commits. Cost: more derivations, larger authenticator payload, and the aggregator must accept an unbounded set of signing keys per wallet. Deferred to a future revision. + +### 9.3 Forward secrecy across versions + +Each version uses a fresh `xorKey_{side, V} = SHA-256(xorSeed || [side] || be32(V) || bytes_of("xor"))` (bare SHA-256 via DataHasher; NOT HKDF-Expand). Knowing the plaintext CID at version `V` does not reveal `xorKey(A, V)` or `xorKey(B, V)` without `xorSeed`. Therefore: + +- Compromise of one version's plaintext (e.g., via a leaked IPFS CAR) does NOT compromise any other version's ciphertext. +- Compromise of the blinded leaf values does NOT compromise the plaintext without `xorSeed`. + +### 9.4 Content concealment + +Leaf ciphertexts are XOR of a 32-byte plaintext with a uniformly-random 32-byte one-time pad. Without the pad, each ciphertext byte is uniformly random. The aggregator sees values informationally indistinguishable from fresh random bytes. + +### 9.5 Length concealment + +The 1-byte length prefix is XOR-blinded by the same pad as the rest of the leaf. External observers cannot read `L`. The 64-byte envelope is constant per publish. + +### 9.6 Privacy summary table + +| Threat | Mitigated by | Residual risk | +|---|---|---| +| Aggregator reads CID | XOR blinding with `xorKey(side, V)` | None (cryptographic) | +| Aggregator clusters wallet's commits across versions | — | **All pointer commits linkable via stable `signingPubKey`** (W-2) | +| External observer correlates chain pubkey → commits | `pointerSecret` derived from `mk` via HKDF (not from chain pubkey) | None (cryptographic) | +| Observer infers CID length | 64-byte fixed envelope; L-byte XOR-blinded | None | +| Observer infers version count | — | Observable via probe patterns (acknowledged) | +| Observer infers activity cadence | — | Observable (acknowledged) | +| IP / timing correlation of a signing-key-clustered commit stream | — | Observable; linkability deanonymizes the stream (documented, deferred mitigation) | +| Probe-sequence fingerprint across sessions (§9.7) | — | Observable per-session; cross-session clustering even when IP rotates (documented, v2 mitigations deferred) | + +### 9.7 Probe-sequence fingerprint (v3.1 disclosure) + +The discovery algorithm's probe sequence (Phase 1 exponential expansion, Phase 2 binary search — §10) is **deterministic in `(V_true, localVersion)`**. An aggregator operator who logs per-session probe sequences across many sessions can correlate sessions originating from the same wallet by recognizing the characteristic `(lo, hi, mid_1, mid_2, ...)` pattern that falls out of the seeded binary search, **even when the wallet rotates IPs between sessions**. This is a strictly stronger clustering signal than `signingPubKey` alone: `signingPubKey` is sent in every authenticator at publish time, but probe-GET traffic during pure recovery need not include it — yet the probe pattern itself still betrays the wallet. + +Mitigations considered but deferred to v2 future work: + +- **Randomized Phase 1 exponential base** (e.g., each session draws a fresh factor in `[1.5, 2.5]` from a session-local PRNG so the doubling schedule varies). +- **Decoy probes** — each real probe is accompanied by `k` fake probes at unrelated request IDs drawn from the same `pointerSecret`-derived family, making the operator's job `O(C(real+fake, real))` harder. +- **Batching across sessions to reuse cached `V_true`** — avoid repeating the search when `localVersion` is already known. + +None of these are part of v1; all are explicitly called out as probe-sequence hardening to ship later. See spec §11.10. + +### 9.8 Valid-version continuity (v3.2) + +The pointer layer treats discovery as a search for the latest VALID version, not simply the latest-included version. A "valid" version has: verified inclusion proofs for both sides, a well-formed XOR-decoded payload, a parseable sha2-256 CID, a fetchable CAR within `MAX_CAR_BYTES` / `MAX_CAR_FETCH_MS`, and a deserializable UXF package. Any version failing these checks is "corrupt" — it may exist in the aggregator SMT (from prior buggy clients, aborted publishes, or gateway-level CAR corruption), but it is SEMANTICALLY IGNORED. + +Discovery finds the latest INCLUDED version via exponential+binary search (§10.2), then walks backward skipping up to `DISCOVERY_CORRUPT_WALKBACK` corrupt versions (spec §8.2 Phase 3). The first valid version found is returned. New valid publishes at `latest_valid_V + 1` are legitimate — a publisher does NOT need to resolve or clean up intermediate corrupt versions; they are permanent SMT residue that everyone skips. + +Critically, each Sphere client implements this independently; no coordination is needed. Two clients looking at the same wallet pointer stream with corrupt versions at `v = 7` and `v = 8` will both skip to `v = 9` (or earlier) as the latest valid and continue from there. There is no consensus step — the rule is a pure client-side skip policy. + +If Phase 3 walk-back exhausts `DISCOVERY_CORRUPT_WALKBACK` consecutive corrupt versions (default `64`), recovery bails with `AGGREGATOR_POINTER_CORRUPT_STREAK`. The operator-facing `acceptCorruptStreak(walkbackLimit)` API (§15.2.1) extends the walkback for a single attempt. See spec §10.8 for the normative rule. + +This rule REPLACES the r3.1 §10.2.6 "fresh-install corrupt-payload → BLOCKED" behavior, which was both narrower (it only fired when `localVersion == 0`) and harder to recover from (each corrupt residue version required a distinct operator override). Valid-version-continuity generalizes to any position in the version stream and restores self-healing publish semantics. + +### 9.9 v3.3 security-and-privacy additions + +Revision 3.3 closes four surface-area issues in the privacy/security argument without changing the underlying cryptographic primitives. These are NEW concerns to the narrative; each is fully specified in the companion spec. + +**Probe predicate changed to OR (narrow usage).** The inclusion predicate used inside discovery remains AND-over-sides for the global Phase 1 / Phase 2 search (§10.5). Spec §8.1 also defines an OR-over-sides predicate used by a narrow partial-publish retry window, so a single-side landed commit does not non-monotonically "disappear" from later probe traces. From the arch-level privacy angle: this does not change the §9.7 fingerprint disclosure, because the probe sequence is still deterministic in `(V_true, localVersion, corrupt-version set)`. No new observability surface is introduced. + +**Trust base rotation (spec §8.4.1, simplified v3.4).** The bundled `RootTrustBase` ages out. When the aggregator rotates its BFT validator set, the SDK-bundled trust base no longer verifies fresh proofs (`NOT_AUTHENTICATED`). The arch-level rule: treat `NOT_AUTHENTICATED` plus an epoch mismatch as a rotation signal (not as BLOCKED-trigger material); surface `AGGREGATOR_POINTER_TRUST_BASE_STALE` and require an SDK update whose bundled trust base carries the new epoch. There is no runtime-refresh flow in v1 — rotation remediation is release-shipped. This closes a "trust-base age-out bricks otherwise-live wallets" failure mode, traded for SDK-release cadence as the rotation bottleneck. + +**Shared trust base vs L4 (spec §8.4.2 — canonical rule as of v3.4).** The `RootTrustBase` the pointer layer consumes MUST be the same instance the outer SDK uses for L4 token verification — specifically, consumed via `OracleProvider.getRootTrustBase()` (or the equivalent SDK hook). Implementations MUST NOT instantiate a separate trust base for the pointer layer. Asymmetric trust bases create an attacker path where one surface is forgeable and the other is not, which is enough to compromise wallet state regardless of which layer is "stronger." Shared trust collapses both attack surfaces into one — and is trivially satisfied in v3.4 because the bundled trust base already flows through L4's `OracleProvider` today. + +**TLS simplified to standard WebPKI (spec §8.4.3).** Aggregator HTTPS uses TLS ≥ 1.3 with standard WebPKI validation. Because `RootTrustBase` is embedded in the SDK bundle (not fetched over the network), an on-path TLS MITM cannot forge `InclusionProof.verify` outcomes — the cryptographic anchor lives in the SDK, independent of the TLS session. Runtime cert pinning, CA diversity, IP diversity, and bundled mirror-list integrity — all retired in v3.4 — applied only when the trust base was fetched over the wire, and will re-emerge in v2 alongside runtime-fetched trust-base + L1-alpha-anchored fingerprinting (§12). + +--- + +## 10. Logarithmic Version Discovery + +### 10.1 Problem + +Given the master key, find the largest `V` such that `(r_A(V), r_B(V))` are both included, with nothing at `V+1`. The total published history `V_true` could be anywhere from 0 to millions. + +### 10.2 Strategy: exponential probe, then binary search + +**Phase 1 — Exponential probe (upper bound).** Starting from `V_init` (seeded from `localVersion` if available — reviewer W-7), probe at doubling intervals until we find a `V_hi` where BOTH sides are excluded. If `V_init` is already excluded, we know `V_true < V_init`. + +**Phase 2 — Binary search (exact value).** Bisect over `[V_lo, V_hi]`. Each step probes both sides at `mid` and halves the interval. + +**Probe scope — both sides at every probe (reviewer C-3).** The v1 draft's optimization of probing only side A was rejected because it has a correctness gap under partial publish: during a partial-publish window, only one side is included, and a one-side probe can mis-classify. Probing both sides in parallel at each step keeps the round-trip count the same (two parallel calls per step) while closing the gap. + +### 10.3 Parallelism = 1 for the binary-search phase (reviewer W-6) + +The binary-search phase is serial by construction — each step depends on the result of the previous. Within each step, the two side-A and side-B probes at the same `V` are issued in parallel, but step `k+1` cannot begin until step `k` returns. + +**Phase 1 exponential-expansion speculative probing is future work.** The v1 draft's `DISCOVERY_PARALLELISM = 4` constant is removed. A future optimization may speculatively probe `V = V_init, 2·V_init, 4·V_init, ...` in one burst and take the first-excluded result; this is explicitly a v2 optimization and is NOT part of this design. + +### 10.4 Complexity + +- Phase 1: `O(log V_true)` probes. +- Phase 2: `O(log V_true)` probes. +- Overall: `O(log V_true)` round-trip latencies; each probe ≈ 2 parallel RPCs. + +At ~100 ms per RPC and `V_true = 10^6`, ~20 probes ≈ 2 seconds.

These are decided-and-deferred (not open questions): + +- **Bundled trust base as centralized trust root (v3.4).** v1 ships `RootTrustBase` inside the SDK bundle (§6.5). Supply-chain compromise of an SDK release beats every downstream wallet at once — L4 and the pointer layer are both anchored to the same bundle. +- **Runtime-fetched trust base with L1-alpha-anchored fingerprint (v2 work).** Replace the SDK-bundled trust base with a runtime-fetched one whose fingerprint is committed to the ALPHA (L1) chain (e.g., a coinbase OP_RETURN or governance-signed record). Wallets then verify at init time that the trust base delivered by the aggregator matches the latest L1 attestation. This closes the supply-chain gap of the bundled-trust-base model AND unblocks multi-mirror TOFU (≥ 2 independently-addressed aggregator mirrors returning byte-identical trust bases) as a meaningful defense — together with cert pinning, CA diversity, and mirror-list integrity. All of these become applicable only once runtime fetch is in scope, and are consequently paired in the v2 roadmap. See spec §11.13 item (i). +- **Backup/restore `MARKER_CORRUPT` UX.** A `pending_version` marker restored from a backup taken mid-publish surfaces as `AGGREGATOR_POINTER_MARKER_CORRUPT`, which today requires the operator escape hatch (`clearPendingMarker()`) — not ideal for end-user recovery flows. +- **Denylist governance.** The well-known-test-key denylist (spec §11.12) is client-bundled; updates require a client release cycle, and there is no signed revocation channel. + +--- + +## 11. Consistency Model + +A new section reviewers specifically asked for (W-4, N-1), because the system combines two very different models under one recovery contract. + +### 11.1 The pointer layer is per-wallet linearizable + +- The aggregator SMT is BFT-ordered.

CAR contents merged from OpLog remain CRDT (commutative, order-independent). The pointer layer is the **only** linearization point; everything downstream stays eventually-consistent. + +--- + +## 12. Failure Modes & Degraded Operation + +### 12.1 Aggregator unreachable during publish + +**Preserved invariants.** CAR is pinned; `tokens.bundle.{cid}` is in OrbitDB; other peers can still replicate via gossipsub. Pointer retry is safe (payloads are deterministic — §4.5). + +**Handling.** Log failure, emit `pointer:publish_failed`, do not throw from `flushToIpfs`. Next flush recomputes `V_next`. If the failure was "first submission OK, second submission timed out," §7.2 pending-tuple logic ensures the retry uses byte-identical payloads. + +### 12.2 Aggregator unreachable during recovery — blocked-publish regime (C-5) + +See §6.7. The wallet operates read-only, emits `pointer:publish_blocked`, and refuses to publish until aggregator reachability + verified probe complete. **No silent history erasure.** + +### 12.3 Partial publish (A committed, B not) + +**Detection.** Probing both sides (§10.2) catches this: `r_A(V)` includes, `r_B(V)` excludes. + +**Handling (reviewer C-3 — retry side B at same V):** + +1. Re-submit side B at the same `(V, side=B)` with the byte-identical payload from `padSeed`-derived padding (§4.5). The requestId is deterministic in `(pointerSecret, V, side)`. +2. If the aggregator returns REQUEST_ID_EXISTS, treat as idempotent success — the previous submission had landed and the ack was lost. +3. Else, proceed with the retry; bounded attempts with jittered backoff (§7.3). +4. **Do NOT skip to V+1** (rejected optimization). + +**Why this is safe:** deterministic payload means re-submission cannot encrypt a different plaintext under the same OTP. §7.2 crash-safety logic further guarantees this is the case even across wallet restarts. + +### 12.4 Corrupted CID bytes after decrypt + +Causes: derivation drift between publisher/recoverer (e.g., library version skew on HKDF), storage corruption at the aggregator (extremely unlikely), or I-1 violation. + +Handling: abort recovery, log diagnostic (partial bytes, expected length, multihash header, codec), fall back to §12.2 empty-state path. Live peer replication will still deliver the OpLog. This is a hard error, not a soft retry — same inputs produce same corruption. + +### 12.5 Local version counter lost but pointer exists + +Counter is an optimization. First publish after loss computes `V_next = 1`, submission rejected, recovery triggers, counter restored. One extra round trip; no data loss. + +### 12.6 Multiple wallets on one device + +Each wallet has a distinct `mk`, therefore a distinct `pointerSecret`, therefore distinct request IDs. Local pending tuples and version counter are scoped by wallet (keyed by `signingPubKey` or chain pubkey). + +### 12.7 Aggregator signs a false exclusion + +Exclusion proofs are verifiable against the SMT root. A lying aggregator must fork the root, which is detectable. Our v1 defense is `InclusionProof.verify` against the TOFU'd trust base (§6.5); v1.5 cross-mirror check and v2 L1 anchoring strengthen this. + +### 12.8 Aggregator reset + +See §5.5. Explicit `Profile.resetPointerVersion()` migration hook. + +### 12.9 CAR unavailable after successful recovery (v3.1, tightened v3.3) + +When discovery yields a verified pointer at `V > 0` and the inclusion proofs at `(r_A(V), r_B(V))` pass `InclusionProof.verify`, but `fetchFromIpfs(cid)` returns 404 / unreachable / times out on *every* configured gateway, the wallet enters an `AGGREGATOR_POINTER_CAR_UNAVAILABLE` state. This is distinct from §12.2 BLOCKED: here the aggregator IS reachable and `V_true` is trustlessly known; only the CAR bytes are missing. + +Behavior (narrative; spec §10.7 owns the normative rule): + +- Raise `AGGREGATOR_POINTER_CAR_UNAVAILABLE` to the caller. +- Do NOT advance `localVersion` past `V_true`. +- Refuse subsequent `publish()` calls until EITHER the CAR becomes fetchable on retry OR the caller invokes the explicit operator override `acceptCarLoss(version)` under the v3.3 hardened preconditions. +- Emit `pointer:recover_car_unavailable { version, cid }` for UI surfacing; emit `pointer:car_loss_pending { version, retriesRemaining }` while persistent-retry is still active; emit `pointer:car_loss_aborted_peer_found { version }` when peer discovery aborts the override path; emit `pointer:car_loss_accepted { version }` when the override is finally invoked. + +**Phase 3 split (v3.3 — spec §8.2).** The §8.2 walk-back distinguishes two failure categories: + +- `SEMANTICALLY_INVALID` — the payload is structurally bad (XOR-decode fails, CID does not parse, CAR fails to deserialize). **Walk back past it** — this is ordinary residue from prior buggy clients and cannot be fixed by waiting. +- `TRANSIENT_UNAVAILABLE` — all gateways returned errors after the per-fetch retry budget (`MAX_CAR_FETCH_RETRY`) was exhausted. **Do NOT walk back.** Raise `AGGREGATOR_POINTER_CAR_UNAVAILABLE` and enter the §12.9 state. Walking back would silently discard a valid bundle whose gateways happened to be down at fetch time — a token-loss path. + +**acceptCarLoss hardening (v3.3 — spec §10.7.1).** The v3.1 single-call override is replaced with a multi-check procedure: + +1. Capability gate: `allowOperatorOverrides` must be set at SDK init time. +2. Persistent multi-gateway retry: the wallet must have performed `CAR_FETCH_PERSISTENT_RETRY_ATTEMPTS` retries distributed over `CAR_FETCH_PERSISTENT_TOTAL_DURATION_MS` (24 h) across the full gateway set. The persistence clock survives restarts. +3. Peer availability check: before the override proceeds, the wallet polls OrbitDB gossipsub / Nostr for `POINTER_PEER_DISCOVERY_MS` (10 min) looking for a peer that holds the unfetchable bundle. A positive discovery aborts the override (`pointer:car_loss_aborted_peer_found`) — the peer's replication will heal the missing CAR without data loss. +4. Republish-before-advance: the wallet MUST republish the current valid local state (a freshly-flushed CAR) as a new pointer version BEFORE the override advances `localVersion` past the lost one. This prevents the case where `acceptCarLoss` succeeds, the local state diverges from aggregator state, and the next crash loses the divergence. + +The arch-level narrative is: `acceptCarLoss` is not a simple setter. See spec §10.7.1 for the full precondition list. + +Also subject to v3.1 CAR size/fetch caps and associated error codes (spec §3 / §10.7): excessively large CARs or fetches exceeding the progress-rate or wall-clock timeouts abort locally rather than blocking progress indefinitely. v3.3 tightens these caps to progress-rate (`MAX_CAR_FETCH_STALL_MS`) and total-duration (`MAX_CAR_FETCH_TOTAL_MS`) variants, replacing the single `MAX_CAR_FETCH_MS` (see spec §8.5 / §3 `MAX_CAR_FETCH_*` constants). + +### 12.10 Async-await convention in arch pseudocode (v3.1) + +All SDK calls shown in arch pseudocode (`.digest()`, `SigningService.createFromSecret`, `RequestId.createFromImprint`, `Authenticator.create`, `aggregatorClient.submitCommitment`, `InclusionProof.verify`) are asynchronous; the `await` keyword is elided for readability.

Spec §13 is the normative owner of all signatures; the arch document reproduces them verbatim: + +- `acceptCarLoss(version: number): Promise>` — caller opt-in that unblocks publish after §12.9 `AGGREGATOR_POINTER_CAR_UNAVAILABLE`; emits `pointer:car_loss_accepted` telemetry. **v3.3: this is NOT a simple setter.** The method has complex preconditions: capability gate (`allowOperatorOverrides`), persistent multi-gateway retry over `CAR_FETCH_PERSISTENT_TOTAL_DURATION_MS` (24 h), peer-availability check via OrbitDB/Nostr for `POINTER_PEER_DISCOVERY_MS` (10 min), and republish of the current local state BEFORE advancing `localVersion` past the lost version. See spec §10.7.1 for the full precondition list. +- `clearPendingMarker(): Promise>` — operator escape hatch that removes a stuck `pending_version` marker (e.g., corrupted, orphan after a non-recoverable crash); emits `pointer:marker_cleared` telemetry. **v3.3: gated on `allowOperatorOverrides` capability AND human confirmation, and SETs BLOCKED after clearing the marker** — the wallet must re-reconcile against the aggregator before it can trust that its version counter is accurate. +- `getProbeFingerprint(): string` — optional diagnostic returning a short stable hash of the last discovery probe sequence, intended for operator analysis of the §9.7 fingerprint disclosure. Returns empty string if no probe has run since init. Not secret; MAY be logged. +- `acceptCorruptStreak(walkbackLimit?: number): Promise>` — v3.2 operator escape hatch that extends the §9.8 corrupt-version walk-back beyond `DISCOVERY_CORRUPT_WALKBACK` for a single attempt, used when a pathological OpLog of consecutive corrupt residue (long tail of prior-client bugs or adversarial grinding) has exhausted the default cap with `AGGREGATOR_POINTER_CORRUPT_STREAK`. **v3.3: walk-back is bounded below by `localVersion`** — it will never walk past a previously-confirmed valid version of our own making, and raises `AGGREGATOR_POINTER_WALKBACK_FLOOR` if that floor is hit. +- `isReachable(): Promise` — v3.3 clarifies this is a **live probe that performs `InclusionProof.verify`** on a test request ID; it is NOT an HTTP-level ping. A successful return implies the aggregator responded AND the trust base verified the response, which is the actual precondition for clearing BLOCKED (spec §10.2.4). + +No new API methods are introduced in v3.3 beyond the precondition tightening noted above.

Read-only; no code changes made. + +## Summary + +One-line verdict: **BLOCKING GAPS** — 2 of 5 rules are effectively absent. +Same-tokenId longest-**valid**-chain and proof-enrichment are not +implemented at the structural layer that performs JOIN. JOIN today relies +on instance-chain prefix-subset logic that deconstructed token-roots +never populate, and the manifest collapses same-tokenId collisions via +"source wins". Phase D must land a real per-token JOIN resolver before +the pointer work can rely on a deterministic joined view. + +## Rule-by-rule findings + +### Rule 1: Manifests UNIONED + +- **Status:** PARTIAL +- **Evidence:** + - `profile/profile-token-storage-provider.ts:455-464` — `load()` + iterates every active `tokens.bundle.*` ref and calls + `mergedPkg.merge(pkg)` once per bundle. + - `uxf/UxfPackage.ts:473-510` (`mergePkg`) — merges element pools by + content hash and iterates `source.manifest.tokens` into the target + manifest at `:493-495`. + - `profile/consolidation.ts:183-192` — the consolidation path uses the + same `mergedPkg.merge(pkg)` loop. +- **Gap:** The union is LAST-WRITER-WINS on collision + (`mutableManifest.set(tokenId, rootHash)` at + `uxf/UxfPackage.ts:494`). When two bundles list the same tokenId with + different root hashes (e.g. 5-tx chain vs 3-tx chain — token-roots are + content-addressed so their hashes differ by tx-list length/content), + the later-merged bundle simply overwrites the manifest entry. The + losing root remains in the pool as an orphan but is no longer + reachable via `manifest.tokens.get(tokenId)`. The iteration order + over `activeBundles` in `profile-token-storage-provider.ts:455` is + effectively the Map insertion order of `listActiveBundles()`, so the + "winner" is implementation-defined rather than rule-driven. + +### Rule 2: Element pools UNIONED + +- **Status:** IMPLEMENTED +- **Evidence:** + - `uxf/UxfPackage.ts:477-490` — every incoming element is re-hashed + (Decision 7), verified against its key, and inserted into the target + pool only if not already present. This is exactly the + content-hash-dedup union described in §10.4 rule 2. + - `uxf/element-pool.ts:28-55` — `ElementPool.put()` is idempotent on + content hash, which backs the dedup semantics. +- **Gap:** None for the pool itself. Note the related consequence: the + losing token-root from Rule 1 still lives in the pool (good for Rule 4 + in principle) but there is no code that subsequently uses it. + +### Rule 3: Same-tokenId longest-valid-chain + +- **Status:** ABSENT +- **Evidence:** + - `uxf/instance-chain.ts:296-362` (`mergeInstanceChains`) resolves + same-element divergence via **hash-set prefix** detection: if every + hash in the source chain appears in the target chain it is a prefix, + and vice versa. This is strictly a set-containment test; it does + not look at transaction arrays, inclusion proofs, or chain validity. + - `uxf/deconstruct.ts:114-121` — every deconstructed element is + created with `predecessor: null`. `addInstance()` is the only + populator of instance chains (`uxf/instance-chain.ts:73-157`) and + is never invoked during deconstruction or merge. `rg addInstance` + under `modules/` and `profile/` returns no hits. + - Therefore `mergeInstanceChains()` has no data to work with for + normal token-roots — two different-length versions of the same + token end up as two independent token-root elements, and the + manifest arbitrates via the last-writer-wins rule 1 behaviour. + - `profile/token-manifest.ts:113-152` (`collectHeads`) scans + instance-chain entries by tail equality, but because chains are + empty in practice, it returns a single head and classifies every + token as `valid` regardless of whether a longer bundle existed. + - There is a TXF-level analogue in + `modules/payments/PaymentsModule.ts:672-702` (`isIncrementalUpdate`) + and `:748-768` (`findBestTokenVersion`) that does compare + transaction arrays and counts committed (proof-bearing) txs — but + this operates on already-assembled `TxfToken` pairs for the + legacy archived/forked maps, not on bundles during JOIN. +- **Gap:** No code path during bundle JOIN: + 1. Validates the transaction chains of the two candidate token-roots. + 2. Compares their lengths. + 3. Inspects inclusion-proof presence to distinguish VALID (longest + with proofs) from INVALID (longer but broken). + 4. Discards an invalid longer chain in favour of a shorter valid one. + 5. Flags unresolvable divergence for Section 10.7 handling. + +### Rule 4: Proof enrichment + +- **Status:** ABSENT +- **Evidence:** + - `uxf/UxfPackage.ts:545-562` — `consolidateProofs()` is declared + but throws `NOT_IMPLEMENTED` with the comment + "not implemented in Phase 1 (Decision 9)". + - `uxf/UxfPackage.ts:473-510` (`mergePkg`) does not cross-reference + transactions between bundles: an incoming element is inserted only + if the pool does not already contain an element with the same hash + (`:487`). A pending transaction (no proof) and a finalised + transaction (with proof) are two DIFFERENT elements with DIFFERENT + content hashes, so both land in the pool — but no code then + promotes the finalised version into the token-root's transaction + list for the pending side. + - Manifest overwrite (rule 1) prevents the finalised token-root from + coexisting with the pending one: whichever was merged last wins + the manifest slot, and the orphan is unreachable from assembly. + - `profile/token-manifest.ts` deliberately scopes itself to structural + validity and declares (line 25-27) "the oracle pass is async and + network-dependent" — it does not touch enrichment either. +- **Gap:** No element-level proof lifting between bundles. Rule 4's + example (Bundle A has tx[2] pending, Bundle B has tx[2] with proof → + joined result should have tx[2] with proof) cannot occur: neither the + instance-chain merge nor the manifest merge can produce it. + +### Rule 5: Non-joined coexistence + +- **Status:** IMPLEMENTED +- **Evidence:** + - `docs/uxf/PROFILE-ARCHITECTURE.md:999` — "OrbitDB may contain + multiple non-joined bundles temporarily — this is accepted by + design. JOIN happens on the client when loading." + - `profile/consolidation.ts:10-18` — consolidation is explicitly + background / threshold-driven (3 active bundles), and superseded + bundles are retained for 7 days; between loads each bundle exists + independently as its own `tokens.bundle.*` KV key. + - `profile/profile-token-storage-provider.ts:414-415` — every + `load()` re-derives the joined view; OrbitDB itself is never + mutated by the JOIN. If JOIN fails for a bundle the loop at + `:460-463` simply continues, leaving that bundle available for a + future re-load. + - `uxf/UxfPackage.ts:473-490` — merge operates on an empty target + package (`UxfPackage.create()` at + `profile-token-storage-provider.ts:432`), so input bundles are + never mutated by JOIN either. +- **Gap:** None. This rule is trivially satisfied because the system + simply keeps each bundle's CAR intact on IPFS and its ref intact in + OrbitDB; JOIN is a client-side, read-side derivation. + +## Recommended Phase D adjustments + +Rules 3 and 4 are the blocking gaps. Phase D should not assume a +correctly joined package comes out of `UxfPackage.merge()` today. + +Suggested pre-Phase-D work items: + +1. **Per-token JOIN resolver (`uxf/token-join.ts` or equivalent).** Given + a tokenId and a set of `{rootHash, UxfPackageData}` candidates, + return the `rootHash` to use and a `JoinOutcome` enum + (`single | longest-valid | truncated | divergent`). Inputs: pool + access for walking transaction arrays; decoder for inclusion proofs. + Rule 3 lives here. + +2. **Proof-enriched token-root rebuild.** When the resolver picks the + longer chain but the shorter chain has better proof coverage on the + common prefix, emit a synthesised token-root whose transaction array + is `[enrichedTx0..enrichedTxK, longerTxK+1..longerTxN]`. Put the new + token-root into the pool and point the manifest at it. This replaces + the declared-but-unimplemented `consolidateProofs()` for the JOIN + path. Rule 4 lives here. + +3. **Invoke the resolver from `UxfPackage.merge()` (or a new + `UxfPackage.join()` flavour).** The current `mergePkg` manifest + collision handler at `uxf/UxfPackage.ts:493-495` must call the + resolver instead of blindly overwriting. Because `mergePkg` is used + both by runtime JOIN (`profile-token-storage-provider.ts:459`) and + by consolidation (`profile/consolidation.ts:192`), both sites benefit + automatically. + +4. **Extend `deriveStructuralManifest()` to observe the resolver's + `JoinOutcome`** rather than relying on instance-chain siblings — the + current tail-anchored detector at `profile/token-manifest.ts:113-152` + will mark nothing as conflicting because chains are never populated. + +5. **Test matrix:** at minimum the four variants called out in §10.4 — + both-valid-one-longer, both-valid-same-length-different-proofs, + one-valid-one-invalid, divergent-siblings — plus a rule-4 enrichment + case.

IPNS is fully removed — there is no fallback, no `--no-pointer` flag, and no legacy IPNS runtime path. The `profile-ipns.ts` file survives only as a one-shot migration reader (T-D6b), then is explicitly deleted (T-D6c). This decision is load-bearing and not reversible within this plan. + +The implementation is: + +- **Pure-greenfield** at the module level (new files under `profile/aggregator-pointer/`), with surgical edits to `profile/profile-token-storage-provider.ts` (remove call sites only in T-D6; migration logic extracted to `profile/migration/ipns-reader.ts` — production code, NOT tests/fixtures) and migration + deletion of `profile/profile-ipns.ts`. Migration is **Option A** (auto-triggered): `ProfilePointerLayer.init()` detects a legacy wallet and runs the one-shot IPNS→pointer migration automatically; `tests/fixtures/migration-reader.ts` is a thin test shim that imports `profile/migration/ipns-reader.ts` directly. +- **SDK-native**: all crypto round-trips via `@unicitylabs/state-transition-sdk` (`SigningService.createFromSecret`, `DataHasher`, `DataHash`, `RequestId.createFromImprint`, `Authenticator.create`, `AggregatorClient.submitCommitment`, `InclusionProof.verify`, `RootTrustBase`).

The reviewing agent must approach this as an adversary, not a proofreader. Areas to probe: + +**Phase A:** +- Are HKDF info string byte lengths literally correct? Root = 33 bytes ASCII (`"uxf-profile-aggregator-pointer-v1"` = 33 chars). Each subkey = 26 bytes. Count the chars — do not trust the comment. +- Does `deriveXorKey` and `deriveStateHash` use `DataHasher(SHA256)` (bare SHA-256) NOT `hkdfExpand`? The two look similar. A subtle swap breaks OTP guarantees without any test failure unless the KAT vectors were computed with the wrong primitive. +- Does `derivePadding` use HKDF-Expand from `padSeed`? Confirm it does NOT use `DataHasher`. +- Does `MasterPrivateKey` newtype prevent a derived child key from being passed? Try compiling `derivePointerKeyMaterial(childKeyUint8Array)` — it must error. +- Does the log-scrub test cover `process.stderr`, not just `console.error`? + +**Phase B:** +- What is the exact window during which a crash can reuse an OTP key? Map the sequence: write marker → derive xorKey → build payload → submit. The xorKey is derived deterministically from `(xorSeed, side, v)`. The marker records `v`. If the process crashes after deriving xorKey but before submitting, on restart H13 sees same `v` + same cidHash → idempotent retry (correct). If cidHash differs (crash + new CID), rollback-safe bump increments `v` (correct). Confirm these two branches are mutually exclusive and exhaustive. +- Does the in-process Mutex release in LIFO order? If an exception is thrown after file lock acquired but before in-process Mutex is released, does the `finally` chain release in the right order? +- Does `BLOCKED_FLAG_KEY` use `signingPubKey` (wallet-level), not `addressId` (per-address)? Derive the key for two HD indices and assert they produce the same bytes. + +**Phase C:** +- Can an attacker serve a `Content-Encoding: gzip` response that decompresses to exceed the byte cap? The CAR fetcher must reject `Content-Encoding` before decompression, not after. +- Does the scheduled-zero `setTimeout` fire even if the caller `await`s the submit promise and the runtime suspends? Confirm the timer is registered before any `await` in the retry loop. +- Is H8-idempotent truly safe? If the aggregator returns REJECTED for a request that was already included (racing probe), does the marker check correctly identify this as genuine (burn v) vs idempotent (skip burn)? + +**Phase D:** +- Does T-D0 gap report list all five JOIN rules, not just the ones that were present? An audit that only inventories what exists will miss what is absent. +- Does `fetchAndJoin` get called before `storage.write("profile.pointer.version", validV)`, or after? The SPEC requires the join to succeed before the version is committed. Check the ordering in T-D3c. +- Does T-D6 genuinely remove only call sites (lines 279 + 879 + methods 975–1046) without moving any logic into production code paths? +- Does T-D6c delete `profile-ipns.ts` from all bundles? tsup may still include it if an indirect import survives. +- Does the production-build guard check `process.env.NODE_ENV === 'production'` OR a tsup build-time flag? Confirm both paths are tested. + +**Phase E:** +- Does N14 log inspection actually count IPNS code-path invocations, or just assert migration succeeded? The acceptance criterion requires the count = 1, not just success. +- Does the coverage-matrix audit script check that each H/W finding has a test marked PRIMARY AND a test marked SECONDARY, not just that at least one test references the finding? +- Does T-E25 go/no-go verify that `"O-2-UNRESOLVED"` is absent from all config files, not just `constants.ts`?

The existing `submitCommitment()` shape (`TransferCommitment`) assumes a token-bound transfer — pointer commitments are deliberately NOT token-bound. No interface change needed. + +**Open question:** should we add a discoverability hint to `OracleProvider` (e.g., `supportsRawCommitments: boolean`) or just fail loudly if `getAggregatorClient()` returns `undefined`? Prefer the latter — fewer interface surfaces. + +**SPEC v3.4 addition:** `OracleProvider.getRootTrustBase()` (added by T-C7) returns the embedded `RootTrustBase` instance from `assets/trustbase/.ts` — the same instance `PaymentsModule` / L4 consumes (H6 shared-base contract, SPEC v3.4 §8.4.2). The pointer layer consumes this getter directly; no mirror list, no multi-mirror cross-check, no runtime fetch. Multi-mirror TOFU is v2 future work. + +### 2.2 Nostr transport +Not reused. Pointer layer is strict HTTP JSON-RPC to the aggregator. The one cross-call is the `POINTER_PEER_DISCOVERY_MS` poll over OrbitDB gossipsub / Nostr for the `acceptCarLoss` protocol (SPEC §10.7.1 step 3) — this uses the existing `NostrTransportProvider` and OrbitDB gossipsub pubsub, no new transport. + +### 2.3 BIP32 key derivation (`core/crypto.ts`) +SPEC §4 requires `pointerSecret = HKDF-SHA256-Extract+Expand(walletPrivateKey, info="uxf-profile-aggregator-pointer-v1")`. The existing wallet private key is available via `FullIdentity.privateKey` (hex) in Sphere and Profile; the existing `deriveProfileIpnsIdentity` in `profile/profile-ipns.ts:111–127` already shows the correct HKDF pattern. **No changes needed to BIP32 derivation** — pointer layer derives from the private key post-BIP32 via HKDF, not a new BIP32 path. + +### 2.4 HTTP client / fetch wrapper +`impl/shared/ipfs/ipfs-http-client.ts` is a shared fetch wrapper. The pointer layer's aggregator JSON-RPC path reuses the AggregatorClient's internal HTTP transport (from `state-transition-sdk`), not this one. CAR-fetch with stall-rate enforcement (SPEC §10.7) needs a hardened HTTP layer with: +- Content-encoding header rejection for CAR fetches. +- Per-gateway timeout + retry. + +**SPEC v3.4 scope reduction:** TLS cert pinning (formerly via `MIRROR_CERT_PINS`), bundled mirror-list integrity (formerly via `MIRROR_LIST_SHA256`), and multi-mirror parallel fetch with byte-identical cross-check are **deferred to v2** under the embedded-trust-base model. No pointer-specific HTTP hardening beyond the CAR-fetch stall/encoding concerns above. + +**Open question:** should this live in `impl/shared/ipfs/` (reuse existing HTTP client) or in a new `profile/pointer/http-client.ts` isolated to the pointer path? Under SPEC v3.4 reduced scope, reusing the shared IPFS HTTP client is preferable — no pointer-specific cert-pinning / mirror-list hardening to isolate. + +--- + +## §3 Files that require modification + +### 3.1 `core/Sphere.ts` +- **What changes:** Add `pointer?: { enabled?: boolean; allowOperatorOverrides?: boolean; mirrors?: string[] }` and `allowOperatorOverrides?: boolean` to `SphereInitOptions` (328–390), `SphereCreateOptions` (169–219), `SphereLoadOptions` (220–264), `SphereImportOptions` (265–327). Wire into `load()` (line 947 `initializeProviders()`) and `create()` to attach pointer after `setIdentity()` but before returning. Emit progress step `{ step: 'pointer_recovery', message: 'Recovering from aggregator pointer…' }`. +- **Why:** SPEC §13 requires `allowOperatorOverrides` at init time (capability gate); ARCH §3.3 requires recovery to run during `initialize()`. +- **Risk:** Changes to public `SphereInitResult` / option shapes. Existing callers in `openclaw-unicity`, `sphere` app, `agentsphere` must be verified. +- **Test coverage needed:** N1 (first-run), N14 (legacy IPNS fallback), recovery progress event firing, operator-override gate rejection. + +### 3.2 `profile/profile-storage-provider.ts` +- **What changes:** In `doConnect()` (425–493), after Phase B OrbitDB attach, invoke the pointer-layer `initialize()` (SPEC §10 recovery flow). Pointer recovery MUST run **before** `ProfileTokenStorageProvider.initialize()` because it writes bundle refs that the latter reads (ARCH §3.3). Thread BLOCKED-flag state through to `isConnected()` — a blocked wallet reports a new `readonly` substate. +- **Why:** SPEC §10 recovery is an init-time concern; ARCH §3.3 specifies the trigger point. +- **Risk:** Two-phase connect already has 3 `dbStatus` states (`attached`/`attaching`/`fatal`). Adding pointer recovery states risks combinatorial explosion. Recommend keeping pointer-layer state INTERNAL to the pointer-layer object, surfacing only a single `pointerReady` boolean back to ProfileStorageProvider. +- **Test coverage needed:** Existing `tests/unit/profile/profile-storage-provider.test.ts` must not regress. New tests: pointer init failure during connect must not break cache; BLOCKED state blocks writes but not reads (N7a/N7b). + +### 3.3 `profile/profile-token-storage-provider.ts` +- **What changes:** + 1. `flushToIpfs()` (808–893): replace `publishIpnsSnapshotBestEffort()` call at line 879 with `publishAggregatorPointerBestEffort(cid, nextVersion)`. Preserve the best-effort semantics and the pre-flush `lastPinnedCid` idempotence. + 2. `initialize()` (248–298): replace `recoverFromIpnsSnapshot()` call at line 279 with `recoverFromAggregatorPointer()`. **Keep** the `knownBundleCids.size === 0` trigger condition (ARCH §3.3 unchanged). + 3. Delete or hide `publishIpnsSnapshotBestEffort()` (975–1035) and `recoverFromIpnsSnapshot()` (1046–1085) behind a `pointerAnchor === false` fallback (§5). +- **Why:** ARCH §3.2, §3.3 — this is the primary integration surface. +- **Risk:** `flushToIpfs` is the hot path for every `save()`; any synchronous blocking cost added here affects every UI interaction. Pointer publish MUST remain best-effort (never throws, never blocks flush success). +- **Test coverage needed:** N1–N14 (all end-to-end scenarios), plus: `tests/unit/profile/profile-token-storage-provider.test.ts` regression set. + +### 3.4 `core/errors.ts` +- **What changes:** Add 27 new `AGGREGATOR_POINTER_*` codes to `SphereErrorCode` union (lines 27–107), plus `SECURITY_ORIGIN_MISMATCH`. All per SPEC §12. +- **Why:** SPEC §12 mandates specific error codes; Connect dApps and UIs will `switch` on them. +- **Risk:** Low — additive. Any consumer that doesn't handle new codes falls through to the default branch (`showToast(err.message)` in the example). +- **Test coverage needed:** every error code must have at least one emitting test case; TEST-SPEC explicitly enumerates scenarios N1–N14 covering most codes. + +### 3.5 `constants.ts` +- **What changes:** Add a new block `POINTER_CONSTANTS` mirroring SPEC §3 (v3.4) exactly. SPEC v3.4 removed `MIN_MIRROR_COUNT`, `MIRROR_LIST_SHA256`, `MIRROR_CERT_PINS` — none to bundle. +- **Why:** SPEC §3 is normative; constants must be in-bundle so they can't be tampered via runtime config. +- **Risk:** Low. Mirror-related constants are absent in v1; if multi-mirror TOFU returns in v2, they will be reintroduced alongside the bundled trustbase assets. +- **Test coverage needed:** Constants freeze test — verify no runtime mutation. + +### 3.6 `package.json` +- **What changes:** **None** — see §8. + +--- + +## §4 Originated-tag migration (W11) + +SPEC §10.2.3.1 explicitly enumerates the W11 stamping mandate.

The `package-lock.json` is currently conflicted (`UU` in git status) which is orthogonal. + +--- + +## §9 Surprises / unknowns + +1. **Duplicate TokenRegistry bundles (existing, CLAUDE.md-documented).** `Sphere.configureTokenRegistry()` (Sphere.ts:787) runs TWICE — once in `createBrowserProviders`, once in `Sphere.init`, because tsup duplicates the singleton. The pointer layer has a similar risk with its `RootTrustBase` bundled constants. Recommend: make the pointer layer a pure function module with no singleton state; pass `trustBase` explicitly (the embedded instance obtained via `OracleProvider.getRootTrustBase()` per SPEC v3.4 §8.4.2). No `mirrors` parameter in v1. + +2. **IPNS fallback contradicts ARCH §15.1 "delete the file".** ARCH declares `profile/profile-ipns.ts` deleted wholesale. But §5 backward compatibility requires it for N14 (pre-pointer wallet cold-start). **Open question:** strict migration (break N14, matching ARCH §15.3 "no grace period") or compat window? The spec's own test case N14 assumes compat exists — contradiction. + +3. **`ipnsSnapshot` flag rename to `pointerAnchor`.** `ProfileConfig.ipnsSnapshot` (profile/types.ts:67) is documented as default `true`. Renaming per ARCH §15.1 breaks every downstream consumer that sets it explicitly (tests, config files). Recommend: add `pointerAnchor` alongside `ipnsSnapshot`, deprecate the latter across one release. + +4. ~~**Multi-mirror trustbase loader.**~~ **RESOLVED in SPEC v3.4.** The single-embedded-TrustBase-per-network loader (`impl/shared/trustbase-loader.ts:getEmbeddedTrustBase`) is the correct v1 model. No refactor needed per SPEC v3.4 amendment — embedded trust base is the correct v1 model. Multi-mirror TOFU is deferred to v2 and will be a moderate refactor then, not now. + +5. **`OracleProvider.submitCommitment` signature mismatch.** The existing `TransferCommitment` (oracle/oracle-provider.ts:94–103) requires a `sourceToken` — pointer commitments have no source token. Using `oracle.getAggregatorClient()` bypasses this cleanly, but introduces a tighter coupling to the SDK client version. **Flag:** if `@unicitylabs/state-transition-sdk` bumps its commitment API, the pointer layer breaks along with the oracle module. + +6. **Sphere.destroy() and mutex cleanup.** `Sphere.destroy()` at core/Sphere.ts:3827 must release the publish mutex. If a tab is killed mid-publish, the Web Locks API auto-releases; but `proper-lockfile` has a stale-lock timeout (SPEC §7.1.1 says `PUBLISH_BACKOFF_MAX_MS * 2 = 8000ms`). Need a `destroy()` path that explicitly releases. + +7. **Originated-tag stamping during replication.** SPEC §10.2.3 says replicated entries must stamp `'replicated'` at the RECEIVER. But `profile/orbitdb-adapter.ts` currently has `onReplication` callbacks that fire AFTER entries are already persisted locally — which means the stamping must be upstream of persistence. Risk: existing replication code path needs refactor, not just hook. + +8. **BLOCKED flag scope under multi-wallet single-device.** SPEC §10.2.1 scopes `BLOCKED_FLAG_KEY` by `hex(signingPubKey)`. If a user has two wallets on one device (Sphere supports this via `TRACKED_ADDRESSES`), each HD address's pointer layer has its own BLOCKED state. The current CLI's `profile pointer status` must report per-active-address. **Open question:** do we also support querying all addresses at once? + +9. **`init` already does two things.** `Sphere.init()` at 624 either loads OR creates. The pointer layer's recovery is needed in both paths. The progress callback (`onProgress`) already has 14 steps in `load()` — adding a 15th step `pointer_recovery` is fine, but telemetry consumers may depend on the fixed step list. + +10. **`--no-pointer` might be an attack vector.** If a user CLI-flag-disables the pointer layer to "work around a bug," they lose cross-device anchoring. A malicious app on the same device could also pass `--no-pointer` to silently desync. Recommend: `--no-pointer` MUST emit a loud one-time warning per wallet that is persisted; re-enabling must trigger a full recovery. + +11. **HKDF info-string collision.** `PROFILE_IPNS_HKDF_INFO = 'uxf-profile-ed25519-v1'` (profile-ipns.ts:51) and `pointerSecret` uses `'uxf-profile-aggregator-pointer-v1'` (SPEC §4.1). Both derive from the same wallet private key. HKDF domain separation makes outputs independent — but the info-string convention should be linted to prevent future drift. + +12. **`proper-lockfile` vs Node worker threads.** SPEC §7.1.1 requires cross-context mutex. `proper-lockfile` guards against cross-process but NOT cross-thread within the same process. If any consumer runs Sphere in a Node worker_thread, the mutex is insufficient.

However, the plan has eight concrete blind spots relative to the Integration Map's surprises (all 5 material surprises are *acknowledged in risk register* but several are not *addressed by a task*), a critical error-code miscount (SPEC §12 contains 29 `AGGREGATOR_POINTER_*` codes + `SECURITY_ORIGIN_MISMATCH` = 30 total; plan says "23"; integration map says "27"), a contradictory directive for T-E4 (proposes IPNS fallback that ARCH §15.1 and §15.3 explicitly delete with "no grace period"), and several agent-type misassignments. None of these are structural — the plan can ship after incorporating the corrections in §2. Phase A can start *after* C-1, C-2, C-5 are resolved; other corrections can be folded in before their phase gates. + +--- + +## §2 Critical corrections (must fix before proceeding) + +### C-1. Error-code count is wrong — T-A2 acceptance criterion undercounts by 7 +**Where:** Task T-A2 (plan line 298) — "All 23 error codes + `SECURITY_ORIGIN_MISMATCH` with stable string codes". +**What's wrong:** SPEC §12 (lines 1181–1210) defines **29** distinct `AGGREGATOR_POINTER_*` codes plus `SECURITY_ORIGIN_MISMATCH` = **30 total**. The plan says 23+1=24. The Integration Map (§1 row for `core/errors.ts`) says 27+1=28. None of the three match. The original SPEC is canonical. +**Correction:** Rewrite T-A2 acceptance as "All 29 `AGGREGATOR_POINTER_*` codes plus `SECURITY_ORIGIN_MISMATCH` (30 total); emits stable string identifiers matching SPEC §12 table row-for-row; enumeration test asserts exactly 30 members". Add a unit test that parses SPEC §12 table and asserts every row is emitted as a code. +**Responsible:** typescript-pro (T-A2) + security-auditor (spec review). + +### C-2. IPNS fallback contradiction (Integration-Map surprise #2) is not resolved before Phase A kickoff +**Where:** T-E4 (plan line 340) — "Disables pointer layer; falls back to legacy IPNS path (for N14)". ARCH §15.1 (line 1055) — "`profile/profile-ipns.ts` **Deleted.** All exports removed". ARCH §15.3 (line 1086) — "**No grace period required**". +**What's wrong:** The plan's T-E4 proposes retaining IPNS for N14 legacy-wallet recovery. ARCH directly contradicts this. TEST-SPEC §N14 assumes the fallback path exists. Three stakeholders (ARCH, TEST-SPEC, PLAN) are mutually inconsistent. This is a stop-the-line blocker because Phase D's `T-D6` task deletes `profile-ipns.ts` method bodies; if the compat decision flips later, T-D6 must be re-scoped. +**Correction:** Before Phase A kickoff, the spec owners (Aggregator team + SDK team) MUST resolve one of: +- (a) Formally remove N14 from TEST-SPEC (match ARCH); or +- (b) Formally amend ARCH §15.1 to retain `profile-ipns.ts` behind `pointer.enabled === false` under a deprecation window; or +- (c) Reinterpret N14 as "cold-start with NO pointer ever published by anyone" (aggregator returns exclusion at v=1), which is the natural fresh-wallet case and does NOT require legacy IPNS at all. +The plan's current T-E4 implies (b); if (b) is rejected, delete T-E4's "falls back to legacy IPNS path" line and respec N14 to test aggregator-exclusion-at-v=1. Log this as R-14b in the risk register with "BLOCKER — Phase A kickoff" gate. +**Responsible:** Spec editor + Aggregator team + SDK team (must sign off jointly). + +### C-3. Trustbase-loader single-mirror gap (Integration-Map surprise #4) lacks a dedicated task +**Where:** `impl/shared/trustbase-loader.ts` — Integration-Map §1 row flags "Currently returns a single embedded TrustBase per network. Multi-mirror design not yet reflected in loader interface." Plan tasks T-C3/T-C4 build `mirror-tofu.ts` + `trust-base-rotation.ts` but DO NOT edit `trustbase-loader.ts` itself. +**What's wrong:** The loader's interface is not multi-mirror-aware. Without an edit to `trustbase-loader.ts`, T-C3 has to implement its own multi-mirror trust-base resolution path in parallel with the existing loader — creating dual sources of truth. This violates H6 (shared trust-base across L4 + pointer). +**Correction:** Add new task T-C4b to the P-group C-3: "Extend `impl/shared/trustbase-loader.ts` to expose `getMirrorTrustBases(): Promise` returning all mirrors' TrustBase values for cross-check; preserve existing `getEmbeddedTrustBase()` for single-mirror backward-compat. Contract must be idempotent across L4 PaymentsModule + pointer-layer callers (H6 shared-instance)." Depends on T-C3, T-C4; blocks T-D4. +**Responsible:** backend-architect. + +### C-4. `OracleProvider.submitCommitment` signature mismatch (Integration-Map surprise #5) is not addressed in task acceptance +**Where:** Integration-Map §9.5 flags that `oracle.submitCommitment()` signature assumes a `TransferCommitment` with `sourceToken` — pointer commitments have no source token. Plan task T-C1 (aggregator-submit.ts) does not mention this. +**What's wrong:** Without an explicit acceptance criterion, T-C1 will consume `oracle.getAggregatorClient()` by default (the integration map's recommended path), but the plan never verifies this decision. If a reviewer naively wires T-C1 to `oracle.submitCommitment()`, the type system will reject it — but only at integration time (T-D1). Catching this in T-C1 acceptance saves a late cycle. +**Correction:** Amend T-C1 acceptance: "MUST consume `oracle.getAggregatorClient()` directly (returns `AggregatorClient` from `@unicitylabs/state-transition-sdk`); MUST NOT use `oracle.submitCommitment()` (which requires `sourceToken`, not applicable to raw pointer commitments). Unit test asserts `AggregatorClient.submitCommitment(request)` is called with a bare `SubmitCommitmentRequest` — not wrapped in `TransferCommitment`." Mirror change in T-C2 (`aggregator-probe.ts`). +**Responsible:** backend-architect (T-C1) + SDK integration reviewer. + +### C-5. `--no-pointer` attack vector (Integration-Map surprise #10) has no task or mitigation +**Where:** Integration-Map §9.10 flags: "A malicious app on the same device could pass `--no-pointer` to silently desync. Recommend: `--no-pointer` MUST emit a loud one-time warning per wallet that is persisted; re-enabling must trigger a full recovery." Plan T-E4 adds the flag without any mitigation. +**What's wrong:** T-E4 currently disables the pointer layer silently. A malicious local process or CI fixture could silently desync a wallet by passing `--no-pointer` once, waiting for the BLOCKED flag to stay unset, then stealing tokens. No UI warning, no persisted "pointer was disabled" state, no re-enable recovery path. +**Correction:** Amend T-E4 acceptance: "(a) When `--no-pointer` is passed, write a persisted warning cell `POINTER_DISABLED_AT` = now() into `StorageProvider` for the active wallet. (b) Every subsequent `load()` call detects this cell and emits a `pointer:disabled_warning` event until explicitly re-enabled. (c) Re-enabling the pointer layer (next `init()` without `--no-pointer`) triggers a full pointer recovery BEFORE any local writes. (d) CLI prints a single-line warning `WARNING: Pointer layer disabled; cross-device anchoring not active. Re-enable to recover automatically.` to stderr on every invocation while disabled." Add new task T-E4b for the recovery-on-re-enable logic. Depends on T-D4. +**Responsible:** typescript-pro (CLI) + backend-architect (recovery-on-re-enable). + +### C-6. Worker-threads mutex gap (Integration-Map surprise #12) has no mitigation in risk register or tasks +**Where:** Integration-Map §9.12 — "`proper-lockfile` guards against cross-process but NOT cross-thread within the same process. If any consumer runs Sphere in a Node worker_thread, the mutex is insufficient. Flag for v2." Plan §6 risk register has 16 risks; none covers worker_threads. +**What's wrong:** The risk is silently deferred to v2 without a tracking entry. A Node worker_thread consumer (agentsphere, orchestrator, any server-side SDK embed) can subvert the publish mutex and trigger OTP reuse. The plan must at minimum document + detect + fail-closed on worker_thread contexts. +**Correction:** Add R-17 to the risk register: "Worker-thread mutex gap — `proper-lockfile` is cross-process but not cross-thread. Node worker_thread consumers can subvert the mutex. v1 mitigation: T-B4 (Node mutex) detects `isMainThread === false` via `worker_threads` and refuses to initialize, raising `AGGREGATOR_POINTER_UNSUPPORTED_RUNTIME`. v2: expose thread-safe primitive (Atomics + SharedArrayBuffer) and re-enable." Add new sub-task to T-B4 acceptance: "MUST detect Node worker_thread context (via `require('worker_threads').isMainThread === false`) and raise `AGGREGATOR_POINTER_UNSUPPORTED_RUNTIME` at mutex acquisition." Add corresponding test to T-B8. +**Responsible:** typescript-pro (T-B4) + test-automator (T-B8). + +### C-7. Gate for "every API method verified byte-for-byte against SPEC §13" is vague +**Where:** Phase D DONE criterion (plan line 495) — "API surface matches SPEC §13 method-for-method". +**What's wrong:** "Method-for-method" is vague. SPEC §13 has 9 methods plus TypeScript JSDoc contracts with preconditions, postconditions, and error-code enumerations. A literal method-name match would pass with empty stubs. +**Correction:** Rewrite gate criterion: "Conformance test `conformance/pointer/api-surface.test.ts` reflects SPEC §13 byte-for-byte: (a) all 9 method names present; (b) signatures type-check against SPEC-extracted `.d.ts` fixture; (c) every method's documented error-code enumeration is reachable per AST-grep (each error code appears in at least one throw path); (d) capability-gated methods (`acceptCarLoss`, `clearPendingMarker`, `acceptCorruptStreak`) raise `AGGREGATOR_POINTER_CAPABILITY_DENIED` when `allowOperatorOverrides` is absent." Add this as task T-E18b. +**Responsible:** security-auditor + test-automator. + +### C-8. Agent-type misassignment: T-B3 + T-B4 mutex work is cross-process concurrency — requires security-auditor review +**Where:** Task T-B3 (browser Web Locks), T-B4 (Node `proper-lockfile`) assigned to `typescript-pro` only. +**What's wrong:** Mutex correctness is the load-bearing defense against OTP reuse (SPEC §7.1, §11.2, §7.1.1). The H3 finding (multi-mirror TOFU downgrade) and the crash-safety invariant both depend on correctness of these two files. Browser Web Locks API has well-known identity-switch bugs; `proper-lockfile` has stale-lock-timeout edge cases. Neither is vanilla TypeScript. +**Correction:** Add `security-auditor` as mandatory co-reviewer on T-B3, T-B4. Both must be signed off by security-auditor in addition to typescript-pro author. Update §5 agent-assignment table accordingly. +**Responsible:** Agent coordinator. + +--- + +## §3 Warnings (should fix, not blocking) + +### W-1. T-E4 CLI flag implementation: no `profile flush` command listed +**Where:** Integration-Map §6 table lists `sphere profile pointer flush` as an alias for `profile flush`. Plan §3 Phase E (line 262) says "`sphere profile flush` — exposes `publish()` (may already exist; verify)". Plan task list has no T-E for this command — it's only referenced informally. +**Correction:** Add task T-E4c: "Ensure `sphere profile flush` routes to `publish()`; add if missing. Required by N1, N2 scripts." Depends on T-D4. + +### W-2. Per-parallel-group PR boundary (plan §10) breaks when two tasks in the same group edit the same file +**Where:** S11 slot has T-D3, T-D4, T-D7, T-D8, T-D9, T-D10, T-D11 concurrent. T-D11 edits `profile-token-storage-provider.ts`; T-D6 (S12 slot) edits the *same file*. S11 + S12 serialize naturally. But within S11, are T-D7–T-D11 truly parallel? They edit 5 different module files each — yes, non-overlapping. Check: T-D4 (ProfilePointerLayer.ts) + T-D5 (config.ts) — separate files, OK. +**Correction:** Add a pre-PR check: run `git diff --name-only` per-group before squash-merge; if any file appears in two tasks' diffs, serialize them. Document this in plan §10 "Commit Cadence". + +### W-3. Risk R-14 ("PUBLISH_RETRY_BUDGET reset semantics") punts to "assume non-resetting" without a documented test +**Where:** Plan R-14 (line 399). +**Correction:** Add a conformance test to T-E18 Category P: "P9 — PUBLISH_RETRY_BUDGET never resets across publish() invocations; remains a 'consecutive conflict-retries' counter that decrements on retry and resets only on success. Mock aggregator returns CONFLICT 5 times → first 4 retries consume budget, 5th raises `AGGREGATOR_POINTER_RETRY_EXHAUSTED`." This locks the semantic in CI without waiting for spec owner response. + +### W-4. Plan §7 O-2 (RootTrustBase source) is marked "unresolved by Phase-D start → ship static-bundled v1" — no CI check +**Where:** Risk R-3 (line 388). +**Correction:** Add CI check to T-A10 (`.github/workflows/pointer-vectors.yml`): "Verify that `RootTrustBase` source-type constant in `constants.ts` matches a single pre-declared value ('static' | 'remote' | 'hybrid') — fails if 'TBD' or missing." Prevents silent ship. + +### W-5. Plan §3 Phase B deliverable list conflates `mutex-lock.ts (browser)` and `(Node)` as one file — but they're separate platform-specific backends +**Where:** Plan §3 Phase B line 182 / §4 T-B3, T-B4. +**Correction:** Clarify file naming: `mutex-lock.ts` exports platform-agnostic interface; `mutex-lock.browser.ts` and `mutex-lock.node.ts` contain backends. tsup is configured for conditional exports per platform. Update Phase B deliverables block and acceptance criteria in T-B3/T-B4 to reflect three files instead of one. + +### W-6. DM-protocol, peer-discovery via Nostr gossipsub (integration-map §2.2) is handwaved in plan +**Where:** Plan's aggregator-probe + car-loss-tracker reference peer-availability poll but not the gossipsub subscription path. +**Correction:** Add subtask to T-C5: "Integrate with `NostrTransportProvider` for `POINTER_PEER_DISCOVERY_MS` poll — reuse existing gossipsub subscription, no new transport." Add integration test: "CAR loss tracker polls gossipsub; a peer advertisement aborts `acceptCarLoss()` with `pointer:car_loss_aborted_peer_found`." + +### W-7. BLOCKED flag multi-address scope (integration-map §9.8) is undefined in plan +**Where:** Integration-map §9.8 flags open question: "CLI's `profile pointer status` must report per-active-address. Do we also support querying all addresses at once?" +**Correction:** Decide: default `profile pointer status` reports active-address only. Add `--all-addresses` flag for multi-address query. Amend T-E1 acceptance accordingly. + +### W-8. Originated-tag stamping during replication (integration-map §9.7) requires adapter-level refactor, not a hook +**Where:** Plan T-D7–T-D11 stamp at CALLER site. Integration-map §9.7 flags: "Current `onReplication` callbacks fire AFTER entries are already persisted locally — which means the stamping must be upstream of persistence." +**Correction:** Add a new task T-D11b: "Refactor `profile/orbitdb-adapter.ts` `onReplication` to fire the originated-tag downgrade BEFORE persistence to local OpLog; reject entries that fail D5 semantic re-validation pre-persistence. Current post-persistence hook is insufficient (replicated entry lands locally with stale 'user' tag for a window)." backend-architect. + +### W-9. Integration-Map surprise #1 (TokenRegistry-like bundle duplication for trust-base constants) is listed but not a task +**Where:** Integration-Map §9.1 flags risk that `constants.ts` bundle duplication may fork `MIRROR_LIST_SHA256` across bundles. +**Correction:** Add acceptance to T-A1: "`MIRROR_LIST_SHA256` and `MIRROR_CERT_PINS` are exported from a SINGLE top-level `constants.ts`, not duplicated across bundles. Import-path test asserts all consumers reach the same constant (identity equality, not structural)." + +### W-10. Conformance test P1 (proof-verify-always) requires instrumentation, but T-E18 has no instrumentation task +**Where:** TEST-SPEC Category P1 requires counting `InclusionProof.verify()` calls across 100 scenarios. Plan T-E18 is "AST-grep based + KAT vectors" — AST-grep alone can't verify runtime call counts. +**Correction:** Amend T-E18 acceptance: "P1 requires an instrumented proxy wrapping `InclusionProof.verify` that records call counts. Test harness asserts ≥ 1 verify call per scenario that reads aggregator data. Instrumentation is a vitest setup fixture, not an AST-grep check." + +### W-11.

Recovery procedures + +### 3.1 Pre-flight checklist for any operator override + +1. Confirm the wallet is in the state you think it is in. `getPointerSkipReason()` + on the storage provider surfaces the exact skip reason if the pointer + layer failed to construct. +2. Confirm `NODE_ENV !== 'production'` — the production guard will refuse + `allowOperatorOverrides=true` at init (T-E26). The correct workflow + for production is to rebuild with a non-production environment, not + to bypass the guard. +3. Confirm `SPHERE_ALLOW_OVERRIDES=1` is set at the environment level + (not only in code). This prevents a library default from silently + enabling dangerous APIs. +4. Always take a filesystem-level backup of the wallet's data directory + (including the OrbitDB store and the local cache) before invoking + any override. + +### 3.2 BLOCKED state — `clearBlocked` + +**Symptom:** `layer.isPublishBlocked()` returns `true`. Writes are +suppressed; reads still work. + +**Auto-CLEAR conditions (SPEC §10.2.4) — no operator action needed if any fires:** + +- (a) v=1 `PATH_NOT_INCLUDED` exclusion proof on BOTH sides A and B + (the aggregator cryptographically attests that no pointer was ever + published for this wallet). Auto-detected on next `recoverLatest()`. +- (b) a successful `recoverLatest() > 0` that fetches a CAR and merges + the OpLog without error. Auto-detected as a consequence of normal + recovery. + +**Manual CLEAR (operator override) — when auto-CLEAR doesn't fire:** + +Preconditions: +- You have verified via an independent channel that the wallet's + state is recoverable (not an integrity failure). +- You have completed §3.1 pre-flight. + +Procedure: +```ts +const state = await layer.getBlockedState(); +console.log('blocked reason:', state.reason, 'setAt:', new Date(state.setAt)); +// Validate the reason is not UNTRUSTED_PROOF or similar integrity class. +// If it is, STOP — do not clear. + +await layer.clearBlocked(); +// Subsequent publish() attempts will proceed normally. +``` + +**Contraindications:** never clear BLOCKED when the reason is +`UNTRUSTED_PROOF`, `SECURITY_ORIGIN_MISMATCH`, or +`AGGREGATOR_REJECTED`. These indicate integrity problems that require +investigation, not reset. + +### 3.3 Corrupt pending-version marker — `clearPendingMarker` + +**Symptom:** `storage:error` with `MARKER_CORRUPT` on init, or +`getPointerSkipReason()` returns `pointer_init_failed` with a message +referencing the marker. + +**Context:** the pending-version marker protects against a publish +that crashed mid-submit (SPEC §7.1.4). If the marker itself is +corrupt (checksum mismatch per §7.1.5), the layer refuses to +initialize because it cannot safely infer the last publish attempt's +outcome. + +Procedure: +```ts +await layer.clearPendingMarker(); +// Side effect: SETs BLOCKED with reason='marker_corrupt'. +// Next recovery must succeed via §10.2.4 auto-CLEAR before publishes resume. +``` + +**Why the enforced BLOCKED:** clearing the marker alone would let the +wallet retry publishes from an unknown state. Re-running discovery + +recoverLatest before the next publish ensures the wallet re-synchronizes +with the on-network truth. + +### 3.4 CAR unavailable — `acceptCarLoss` + +**Symptom:** `storage:error` with `CAR_UNAVAILABLE`, or discovery's +Phase 3 returns `TRANSIENT_UNAVAILABLE` for the latest version across +extended time. + +**Auto-path:** the pointer layer records each CAR-fetch failure to the +per-version ledger (T-C5). If the wall-clock gate in +`assertAcceptCarLossEligible` (§10.7) is met, `acceptCarLoss` is +invocable. Otherwise it throws `UNREACHABLE_RECOVERY_BLOCKED` — you +must wait for the gate. + +Procedure: +```ts +await layer.recordCarFetchFailure(version, gatewayUrl); +// … repeat as IPFS fetches fail, across multiple load cycles. +// … after POINTER_CAR_LOSS_GATE_MS has elapsed per SPEC §10.7: +const result = await layer.acceptCarLoss(version, cidProducer); +``` + +The `cidProducer` MUST produce the FRESH CID of the wallet's current +token pool — `acceptCarLoss` publishes the new CID at the next +version, effectively abandoning the unavailable historical version. +This is a last-resort recovery; the prior CAR is considered lost. + +**Gossipsub peer-discovery (SPEC §10.7.1 step 3) is not yet wired in +this release.** Acceptance still relies on the wall-clock gate + +ledger. Future versions will add a peer-availability poll before +acceptance. + +### 3.5 Corrupt-version streak — `acceptCorruptStreak` + +**Symptom:** `storage:error` with `CORRUPT_STREAK` (W6 / §10.8). +Discovery walkback hit the walkback-ceiling of consecutive +`SEMANTICALLY_INVALID` versions without finding a valid one. + +**Cause:** usually an aggregator anomaly — a run of versions where +the inclusion proof or CAR fails validation. Less commonly, a +wallet that burned through versions due to a publish-reject loop. + +Procedure: +```ts +// Raise the walkback ceiling for a single subsequent recovery attempt. +// Safety cap is 4096 versions regardless of what you pass. +const { walkbackUsed } = await layer.acceptCorruptStreak(4096); + +// Next recoverLatest() uses the raised ceiling: +const recovered = await layer.recoverLatest(); // picks up walkbackUsed internally +``` + +This is a one-shot gate — the raised ceiling does not persist. If the +next discovery also hits the streak, investigate deeper (likely a +genuine aggregator integrity event). + +--- + +## 4. Backup and restore + +### 4.1 What to back up + +| Location | What | Restored state | +|---|---|---| +| `/orbitdb/` | OrbitDB store (OpLog + heads) | Local bundle refs, operational state, derived caches | +| `/wallet.json` (or IndexedDB `sphere-storage`) | Local cache (identity, pointer version, IPNS sequence if legacy) | Wallet identity, monotonic version counters | +| `/orbitdb/profile-pointer-publish.lock` | Node-only publish lockfile | Not required for restore (it's a leased advisory lock) | + +### 4.2 Restore procedure + +1. Stop any running wallet process that may hold the OrbitDB directory. +2. Copy the backup over the target `dataDir`. +3. On next wallet init: + - Phase A connects the local cache from the restored wallet.json / + IndexedDB. + - Phase B attaches OrbitDB from the restored store. + - Phase C constructs the pointer layer. + - `profile.pointer.version` from the local cache tells the layer + which version it last published. The next publish will target + `max(validV, includedV) + 1`, which self-corrects if the backup + is older than the on-network state. + +**Caveat:** if you restore from a backup older than the on-network +pointer version, the first publish after restore will CONFLICT once — +which triggers `fetchAndJoin` to merge the remote state, then +re-publishes. The bundle refs that the remote merged are added to +OrbitDB; no data loss for tokens whose CID is still pinned. + +### 4.3 Restoring a wallet on a fresh device (mnemonic re-import) + +No backup available? Cold-start recovery path: + +1. Re-import the wallet from mnemonic. Identity is deterministic. +2. On init, `knownBundleCids.size === 0` triggers + `recoverFromAggregatorPointerBestEffort()`. +3. The pointer layer's `recoverLatest()` resolves the latest valid + version from the aggregator, decodes the CID, fetches the CAR + with content-address verification, and records the ref. +4. Subsequent flushes continue normally. + +No IPFS gateway access → the wallet initializes empty. The next flush +from a connected device will publish an anchor; the offline device +can recover when connectivity returns. + +--- + +## 5. IPNS → pointer migration + +Legacy wallets (`profile.ipns.sequence` present, `profile.pointer.migration.done` +absent) auto-migrate on next load via +`profile/migration/ipns-reader.ts:runIpnsToPointerMigration`: + +1. Derives the legacy Ed25519 IPNS identity (HKDF info + `'uxf-profile-ed25519-v1'`, byte-identical to pre-T-D6c). +2. Resolves the legacy IPNS record via the signature-verified routing + API. +3. Iterates active bundle refs, validates each via `CID.parse`, writes + them into OrbitDB via the provider's `addBundle`. +4. Stamps `MIGRATION_DONE_KEY` with a Date.now() string. + +**What's NOT stamped:** + +- Transient resolver failures (exception thrown). The migration + retries on the next load; an operator should not force-stamp in + response to a one-off IPNS outage. +- `null` resolver results (IpfsHttpClient.resolveIpns returns null + for both "no record" and "all gateways down"; the distinction is + not preserved). The migration retries on every load until a + positive resolve — cheap operation. + +**Post-migration:** the IPNS key is never re-published. The wallet is +on the pointer channel permanently. To force a re-migration (for +debugging), delete `MIGRATION_DONE_KEY` from the local cache; the +next load will re-read the IPNS record. + +--- + +## 6. Configuration reference + +### 6.1 `PointerLayerConfig` + +| Field | Production default | Notes | +|---|---|---| +| `allowOperatorOverrides` | `false` | MUST be `false` in production builds (T-E26). Enables `clearBlocked`, `acceptCarLoss`, `clearPendingMarker`, `acceptCorruptStreak`. | +| `allowUnverifiedOverride` | `false` | Dev-only.

Must equal `'1'` alongside the config flag. | unset | + +--- + +## 7. Known residual risks (R-series) + +### R-11 — SDK internal residual copies of ciphertext / private key + +The aggregator submit path zeroes local buffers via `.fill(0)` on exit +(T-C1b, T-C1c). However, the underlying +`@unicitylabs/state-transition-sdk` may retain internal copies via +JSON serialization, base64 encoding, or wrapper classes (notably +`DataHash` and `Authenticator`). These are outside our reach to zero. + +**Mitigation:** SPEC §11.11 documents this as an accepted residual +risk. Keep the SDK version pinned and audited; rotate wallet keys +periodically if operating in a hostile memory environment. + +### R-12 — IPFS gateway MITM on UnixFS snapshot fetch (pre-migration) + +Legacy IPNS snapshots are fetched via `/ipfs/` which does NOT +content-address verify (UnixFS wrapping). A MITM gateway could inject +bundle-ref strings into the snapshot. + +**Mitigation:** the migration reader now validates each +`bundles[].cid` via `CID.parse` before handing to `addBundle` (Wave-3 +remediation). The IPNS record's Ed25519 signature is verified +independently. + +### R-18 — Lock ordering invariant (Node in-process layer above file lock) + +The Node mutex stacks `async-mutex` in-process above `proper-lockfile`. +Acquire in-process-first, file-second; release LIFO. A reversed order +risks deadlock. Enforced by spy-instrumented test in +`tests/unit/profile/pointer/mutex.test.ts`. + +### R-20 — JOIN rule coverage (partial) + +T-D0 audit flagged Rules 3 + 4 as the blocking gap. Rule 3 (longest- +valid-chain selection) is implemented in `uxf/token-join.ts` (MVP). +Rule 4 (synthetic proof-enriched root) is deferred — the UXF JOIN +currently runs last-writer-wins on same-tokenId collisions for the +proof-enrichment case. Under content-addressed transactions this is +safe for the common cases; operators should watch for divergent +outcomes logged by `resolveTokenRoot`. + +--- + +## 8.

Exposes `.data` (raw 32 B digest) and `.imprint` (2 B algo tag big-endian + digest). For SHA-256 the imprint is `[0x00, 0x00] \|\| digest`, total 34 bytes. | +| `DataHasher(HashAlgorithm.SHA256)` | Streaming SHA-256 hasher. `.update(bytes).digest()` returns a `DataHash`. | +| `SigningService` | secp256k1 keypair + ECDSA-recoverable signer. Construction: `new SigningService(privateKeyBytes32)` or `await SigningService.createFromSecret(secret, nonce?)` (which SHA-256-hashes the secret to 32 bytes). Public key is the 33-byte compressed form. Property `.algorithm === 'secp256k1'`. `.sign(transactionHash)` returns a `Signature` whose preimage is `transactionHash.data` (the 32-byte digest — NOT the imprint, NOT any serialization). | +| `Signature` | Compact secp256k1 signature: 64 bytes `r \|\| s` + 1 byte recovery id. Wire-encoded as 65 bytes. | +| `RequestId.createFromImprint(publicKey, imprint)` | Returns the canonical SMT address. Equivalent to `H(publicKey \|\| imprint)` wrapped in a `RequestId` (which extends `DataHash`). | +| `RequestId.create(publicKey, stateHash)` | Convenience wrapper that delegates to `createFromImprint(publicKey, stateHash.imprint)`. | +| `Authenticator.create(signingService, transactionHash, stateHash)` | Builds an authenticator. Internally calls `signingService.sign(transactionHash)` — the **signature preimage is `transactionHash.data`**. `stateHash` is carried alongside but is NOT part of the signed preimage. | +| `SubmitCommitmentRequest(requestId, transactionHash, authenticator, receipt)` | Wire form for aggregator `submit_commitment` RPC. | +| `SubmitCommitmentResponse.status` | Enum: `SUCCESS`, `AUTHENTICATOR_VERIFICATION_FAILED`, `REQUEST_ID_MISMATCH`, `REQUEST_ID_EXISTS`. | +| `AggregatorClient` | JSON-RPC client. `.submitCommitment(requestId, transactionHash, authenticator, receipt)` → `SubmitCommitmentResponse`. `.getInclusionProof(requestId)` → `InclusionProofResponse`. | +| `InclusionProof.verify(trustBase, requestId)` | Returns `InclusionProofVerificationStatus` ∈ { `OK`, `PATH_NOT_INCLUDED`, `PATH_INVALID`, `NOT_AUTHENTICATED` }. | +| `RootTrustBase` | Trust root required by `InclusionProof.verify`.

Pseudocode below omits explicit `await` keywords for readability; treat every SDK call as implicitly awaited. Example: `(await DataHasher(SHA256).update(x).digest()).data` rather than the literal `DataHasher(SHA256).update(x).digest().data` chain that appears in tables. +> +> **`DataHasher(X)` constructor convention.** Throughout this spec, the pseudocode `DataHasher(X)` denotes `new DataHasher(X)`; the `new` keyword is omitted for readability. + +### 4.1 Pointer-layer master secret + +``` +pointerSecret = HKDF( + ikm = walletPrivateKey_bytes_32, + salt = ∅, + info = PROFILE_POINTER_HKDF_INFO, + L = 32 +) +``` + +Where `walletPrivateKey` is the same 32-byte secp256k1 private key the wallet uses for L3 token operations (the HKDF pattern matches `impl/shared/ipfs/ipns-key-derivation.ts`).

This matches `PROFILE-ARCHITECTURE.md §2.1`'s global-keys model, where `identity.masterKey` is wallet-scoped and shared across HD addresses. Implementations that derive `pointerSecret` from any other key position (e.g., `m/44'/coin'/0'` or an address leaf) produce a different pointer chain and break interoperability across Sphere releases. + +### 4.2 Subkey separation + +From `pointerSecret` we derive three 32-byte subkeys with distinct info strings.

The raw constructor `new SigningService(privKey)` treats the input as the scalar directly.

Without this, two concurrent publish pipelines (e.g., debounced flush timer + manual sync, or two open tabs against the same IndexedDB) can produce OTP-reuse by both deriving payloads under the same `(v, side, xorKey)` with different plaintexts. + +Mutex key: + +``` +MUTEX_KEY = "profile.pointer.publish.lock." + hex(signingPubKey) +``` + +**Browser runtime.** Implementations MUST use the Web Locks API: + +``` +navigator.locks.request(MUTEX_KEY, { mode: 'exclusive' }, asyncCallback) +``` + +If the Web Locks API is unavailable (pre-Chrome-69 / pre-Safari-15.4 browsers), implementations MUST refuse to initialize the pointer layer with `AGGREGATOR_POINTER_UNSUPPORTED_RUNTIME`. + +**Node.js runtime.** Implementations MUST acquire an exclusive file lock (e.g., `proper-lockfile`) at the path `/profile//publish.lock`, held for the duration of the publish critical section. The lock file MUST be created with `O_EXCL` semantics. Stale locks (process died without releasing) are detected via the standard `proper-lockfile` stale-lock timeout and are force-breakable only after `PUBLISH_BACKOFF_MAX_MS * 2 = 8000 ms`. + +**Cross-process contention.** If the lock is held by another process or tab, implementations MUST back off with jittered retry up to `PUBLISH_RETRY_BUDGET` attempts before surfacing `AGGREGATOR_POINTER_PUBLISH_BUSY`. + +**Critical-section boundary.** The lock MUST be acquired BEFORE reading `pending_version` and released ONLY AFTER both `localVersion` persist AND marker clear have completed (per §7.1.6 ordering). An identity change (`setIdentity()`) or `disconnect()` during the critical section MUST wait on the lock; the mutex being keyed on `hex(signingPubKey)` ensures a different identity acquires a different lock and does not block the outgoing publish. + +**7.1.2 Per-wallet scoping of the marker.** The pending-version slot MUST be namespaced by the pointer layer's signing pubkey so that multi-wallet devices never share a single slot: + +``` +PENDING_VERSION_KEY = "profile.pointer.pending_version." + hex(signingPubKey) +``` + +See §3 for the constant registration. + +**7.1.3 Durability.** The `pending_version` write MUST be durable (fsync / flush-completed) BEFORE any downstream derivation runs. For IndexedDB this means awaiting `transaction.oncomplete`; for file-based storage, explicit `fsync`. Storage backends that cannot guarantee durability MUST refuse to initialize the pointer layer. + +**7.1.4 Rollback-safe version selection (tightened in H13).** The marker read + v-bump logic is: + +``` +cidHash := SHA-256(cidBytes) +previousEntry := storage.read(PENDING_VERSION_KEY) +if previousEntry is not null: + // Idempotent-replay case (H13, matches arch §7.2): same v AND same cid → + // this is our own crashed publish resuming.

A legitimate marker gap is bounded by: + +- `PUBLISH_RETRY_BUDGET = 5` — per-attempt bumps during a conflict-retry arc (§9). +- Small cohort contention allowances — multi-device races typically chain ≤ 32 bumps (§9.2 reconciliation at `V_true + 1` across a 32-way active cohort). +- Headroom for unusual-but-legitimate scenarios: manual backup/restore from another device, OrbitDB manifest reorgs, test-vector switches, and operator-initiated network migrations. + +`MARKER_MAX_JUMP = 1024` is sized generously (approximately 32× the typical ≤ 32 ceiling) to avoid false-positives on these legitimate-but-unusual flows, at the cost of NOT catching subtle same-window tampering within `[prev.v, prev.v + 1024]`. Tighter thresholds (e.g., 32) are suitable for deployments that can afford to surface `AGGREGATOR_POINTER_MARKER_CORRUPT` on legitimate manual backup-restore flows; operators who lower `MARKER_MAX_JUMP` below 1024 MUST also add explicit UX surfacing of the `clearPendingMarker()` API (§13) for backup-restore scenarios, otherwise a legitimate user restoring state across devices will face an opaque error with no recovery path. See §11.13 item 3 for the documented residual risk. + +Recovery from `AGGREGATOR_POINTER_MARKER_CORRUPT` (regardless of threshold) is via the operator-facing `clearPendingMarker()` API (§13). + +**7.1.5 cidHash integrity.** Implementations MUST NOT truncate the `cidHash`. A marker with `|cidHash| != 32` MUST be treated as corrupt and the publish refused with `AGGREGATOR_POINTER_MARKER_CORRUPT`. + +**7.1.6 Marker clear atomicity.** When a successful publish persists `localVersion = v` and clears the marker, BOTH writes SHOULD occur in a single atomic transaction if the storage backend supports it. If they cannot be atomic, the persistence order is: + +1. Write `localVersion = v`. +2. Clear `PENDING_VERSION_KEY`. + +A crash between (1) and (2) leaves a stale marker at the just-completed `v`, which §7.1.4 will correctly compact on next publish (the `previousEntry.v < currentLocalVersion` branch). + +**Threat defended.** Partial execution + process restart with a different CID. Without this marker, a crashed publisher could re-enter with a new CID at the same `v`, reusing `xorKey_{side, v}` against a different plaintext — a trivial OTP break if both plaintexts ever hit the SMT. + +The `pending_version` slot is cleared only after a successful publish (§7.3, per 7.1.6) or after the publisher definitively abandons the version (e.g., `REQUEST_ID_MISMATCH` — non-retryable). + +**7.1.7 Identity discipline during the critical section (W5).** At publish critical-section entry, the implementation MUST capture `signingPubKey`, `walletPrivateKey`, and all keyed derivations (`pointerSecret`, `signingSeed`, `xorSeed`, `padSeed`, `signingService`) into local constants. These MUST NOT be re-read from a shared identity source during the critical section. Calls to `Sphere.setIdentity()` / `switchToAddress()` while the publish lock is held MUST be queued — they MUST NOT change the publisher's captured key mid-flight. The `MUTEX_KEY` keyed on `hex(signingPubKey)` (§7.1.1) ensures this ordering across async boundaries: a concurrent identity switch that takes the lock for a different signing pubkey does not block the in-flight publish, but a switch targeting the SAME pubkey waits on the lock. + +### 7.2 Payload build + +``` +cidLen = len(cidBytes) +paddingBytes_v = HKDF-Expand(padSeed, be32(v) || bytes_of("pad"), 63 - cidLen) + +full = [cidLen] || cidBytes || paddingBytes_v // 64 bytes +partA = full[0 .. 32) +partB = full[32 .. 64) + +for side in [SIDE_A, SIDE_B]: + part := (side == SIDE_A) ? partA : partB + stateDigest := H(xorSeed || [side] || be32(v) || "state") // §4.4 + stateHash := new DataHash(SHA256, stateDigest) + xorKey := H(xorSeed || [side] || be32(v) || "xor") // §4.5 + ct := xor(part, xorKey) + transactionHash := new DataHash(SHA256, ct) + requestId := RequestId.createFromImprint(signingPubKey, stateHash.imprint) + authenticator := await Authenticator.create(signingService, transactionHash, stateHash) + commitments.push({ side, requestId, transactionHash, authenticator }) +``` + +### 7.3 Submit both sides in parallel + +``` +(resultA, resultB) = await Promise.all([ + aggregatorClient.submitCommitment( + commitments[SIDE_A].requestId, + commitments[SIDE_A].transactionHash, + commitments[SIDE_A].authenticator, + false + ), + aggregatorClient.submitCommitment( + commitments[SIDE_B].requestId, + commitments[SIDE_B].transactionHash, + commitments[SIDE_B].authenticator, + false + ) +]) +``` + +Outcome matrix: + +| resultA.status | resultB.status | Action | +|---|---|---| +| `SUCCESS` | `SUCCESS` | Persist `localVersion = v`.

The earlier `AND` predicate was non-monotonic: a partial-residue version (one side committed, the other absent) could cause the Phase-2 binary search to converge to a stale `V_true`, orphaning bundles. Phase 3 (§8.2) already enforces the stricter validity check (BOTH sides + XOR-decodable + IPFS-fetchable + CAR-deserializable) via `classifyVersion(v)`, so partial-residue versions are correctly walked past there. + +Probing both sides per step still defends against partial-publish ambiguity at recovery: a single-side probe could be misled by a half-published `v` into ambiguous interpretation. With BOTH proofs fetched and verified per probe, Phase 3 has all the material it needs to classify the version definitively. + +### 8.2 Discovery algorithm — valid-version continuity (D1) + +Discovery returns the **latest VALID version**, not simply the latest-included version. + +**Definition — "valid version".** A version `v` is valid iff ALL of the following hold: + +1. Both `requestId_{A, v}` and `requestId_{B, v}` have verified inclusion proofs from the aggregator (i.e., `probe(v) == true` per §8.1). +2. After XOR-decoding both halves (§8.5), the resulting 64-byte `full` buffer has a length prefix `cidLen ∈ [1, CID_MAX_BYTES]`. +3. `full[1 .. 1 + cidLen)` parses as a valid CID (sha2-256 multihash, within-buffer bounds, well-formed varints per §8.5). +4. The decoded CID is fetchable from IPFS via `fetchFromIpfs(cid)` with both `MAX_CAR_BYTES` and `MAX_CAR_FETCH_MS` caps satisfied. +5. The fetched CAR bundle deserializes successfully as a UXF package. + +A version that is included (condition 1) but fails ANY of (2)–(5) is **invalid / corrupt**. Corrupt versions are permanent SMT residue; they are semantically IGNORED by discovery — the pointer layer considers the latest VALID version to be authoritative. + +Phase 1 uses the locally persisted `localVersion` as a lower-bound hint when available; otherwise starts from 0.

This could ORPHAN TOKENS during a temporary IPFS gateway outage — the legitimate latest version would be skipped, and a subsequent publish at walked-back-V+1 would strand the skipped version's inventory. The three-way classification: +- **VALID** — fully reconstructible; return this version. +- **SEMANTICALLY_INVALID** — permanent residue (unparseable CID, content-address mismatch, failed CAR deserialization). Skip and continue walk-back. +- **TRANSIENT_UNAVAILABLE** — all configured IPFS gateways returned network errors, timeouts, or 5xx after `MAX_CAR_FETCH_RETRY = 3` attempts per gateway with exponential backoff. Surface as `AGGREGATOR_POINTER_CAR_UNAVAILABLE` so §10.7 handles it correctly; DO NOT walk back. + +**H4 — publisher uses `max(validV, includedV) + 1`.** The caller of §9 reconciliation MUST target `max(validV, includedV) + 1` as the next publish version.

Skipping past corrupt-included residue by using `includedV + 1` breaks this deadlock cleanly. + +### 8.3 Probe count bounds and walk-back cost + +The §8.2 algorithm has three phases; the first two use inclusion-only `probe(v)`, the third uses the more expensive `isVersionValid(v)` (includes XOR decode + CID parse + IPFS fetch + CAR deserialization). + +- Phase 1 (exponential): at most `log2(DISCOVERY_HARD_CEILING / max(1, lo)) + 1` doublings.

The wallet MUST NOT accept inclusion or exclusion claims based on unverified responses. (Editorial note C12: the variable is `resp.inclusionProof` — matching §8.1 — not a locally-named `proof`; this avoids ambiguity with the r2 `.proof.` field-access bug fixed by F1/r3.) + +**Embedded trust-base anchor (v3.4 — replaces multi-mirror TOFU).** The SDK ships a statically bundled `RootTrustBase` in `assets/trustbase/.ts` (loaded via `impl/shared/trustbase-loader.ts`). This same bundled trust base is the one L4 / `PaymentsModule` already consumes through `OracleProvider` in the current Sphere deployment. The pointer layer behavior is: + +1. **First boot.** Load `RootTrustBase` from the SDK-bundled asset. **No network fetch** occurs to obtain it. +2. **Pinning / subsequent boots.** The pinned value MAY be cached in local storage to survive across sessions, but its *initial* source of truth is the SDK bundle itself. Replacing the pinned value with a runtime-fetched one is NOT performed in v1. +3. **Rotation.** Rotation is detected via the `epoch` field embedded in returned proofs (see §8.4.1). Because the trust base is bundled, the remediation path is to ship a new SDK release whose bundled `RootTrustBase` carries the new epoch. A runtime-refresh flow fetching a fresh trust base from a canonical source is a future hardening (tied to the v2 L1-alpha-anchored trust-fingerprint work; see `PROFILE-AGGREGATOR-POINTER-ARCHITECTURE.md §12`). + +Implementations MUST NOT invent a parallel trust-base provider for the pointer layer. The bundled instance, already consumed by L4, is authoritative (§8.4.2). + +**Note — multi-mirror TOFU and runtime-fetched trust-base integrity deferred to v2.** Multi-mirror TOFU cross-check (byte-identical trust base across ≥ 2 independently-addressed aggregator mirrors) and the associated integrity defenses (cert pinning, CA/IP diversity, mirror-list SHA-256) apply *only* when the trust base is fetched at runtime. In v1 Sphere bundles it, so those defenses have no surface to defend. They become meaningful once the v2 runtime-fetched-trust-base + L1-alpha-anchored trust-fingerprint roadmap item (see `PROFILE-AGGREGATOR-POINTER-ARCHITECTURE.md §12`) ships. Until then, the supply-chain attack surface is the SDK bundle itself; L1-alpha anchoring is the planned defense. + +**§8.4.1 Trust base rotation handling (H5, simplified v3.4).** + +When `InclusionProof.verify` returns `NOT_AUTHENTICATED`, implementations MUST: + +1. **Distinguish rotation from forgery.** If the bundled (or pinned) trust base's `epoch` field differs from the certificate's referenced epoch in the returned proof, rotation is suspected. Rotation is a legitimate operational event (BFT validator set churn); forgery is adversarial. +2. **On suspected rotation.** Raise `AGGREGATOR_POINTER_TRUST_BASE_STALE` (distinct from `AGGREGATOR_POINTER_UNTRUSTED_PROOF`). The trust base is bundled in the SDK (§8.4 embedded trust-base anchor), so the remediation is an SDK update whose bundled `RootTrustBase` carries the new epoch — not a runtime refresh. +3. **On forgery (non-rotation `NOT_AUTHENTICATED`).** Raise `AGGREGATOR_POINTER_UNTRUSTED_PROOF`. Adversarial proof forgery handling is unchanged from r3.3. + +Implementations MUST NOT silently accept a trust base with `epoch` equal to or less than the bundled one — that indicates replay or forgery. Runtime refetch of the trust base is v2 future work (see `PROFILE-AGGREGATOR-POINTER-ARCHITECTURE.md §12`) and is NOT required to resolve rotation in v1; rotation always takes the "ship a new SDK build" path. Without this discipline, a pinned `RootTrustBase` can go stale when BFT validators rotate faster than the SDK release cadence; wallets affected by that gap MUST surface `AGGREGATOR_POINTER_TRUST_BASE_STALE` so operators can drive a release update. + +**§8.4.2 Shared trust base with L4 (H6 — canonical rule as of v3.4).** + +The pointer layer MUST consume `RootTrustBase` via `OracleProvider.getRootTrustBase()` (or the equivalent SDK hook). It MUST NOT bundle its own trust base, load a second copy, or instantiate an independent `TrustBase` provider. L4 (`PaymentsModule`) and the pointer layer share the same embedded `RootTrustBase` instance, loaded once by the SDK from `assets/trustbase/.ts` (§8.4). + +Implementations MUST NOT instantiate a separate `TrustBase` provider for the pointer layer; doing so creates asymmetric trust guarantees. An attacker who cannot forge the pointer-layer trust base but CAN forge the L4 trust base still steals tokens via the L4 path — and vice versa. Shared trust collapses both attack surfaces into one. + +This is an integration-shape requirement, not a byte-level change. It makes the pointer layer compatible with the current Sphere deployment out of the box: L4 is already the source of truth for embedded trust. + +**§8.4.3 TLS discipline (v3.4 — simplified).** + +All aggregator communication MUST use HTTPS with TLS ≥ 1.3. + +Aggregator HTTPS connections use standard WebPKI certificate validation. Because the `RootTrustBase` is embedded in the SDK bundle (§8.4) rather than fetched at runtime, an on-path TLS MITM cannot forge `InclusionProof.verify` outcomes — the embedded trust base is the cryptographic anchor, independent of TLS. The supply-chain attack surface is therefore the SDK bundle itself, not the TLS session. + +Runtime cert pinning, CA diversity, IP diversity, and bundled-mirror-list integrity (the defenses removed in v3.4) apply only to the v2 runtime-fetched-trust-base model. They are planned alongside L1-alpha-anchored trust-fingerprinting (see `PROFILE-AGGREGATOR-POINTER-ARCHITECTURE.md §12`), which closes the bundle-supply-chain gap at the same time. + +### 8.5 CID reconstruction + +Once Phase 2 returns `V > 0`: + +``` +(respA, respB) = await Promise.all([ + aggregatorClient.getInclusionProof(requestId_{SIDE_A, V}), + aggregatorClient.getInclusionProof(requestId_{SIDE_B, V}), +]) + +assert respA.inclusionProof.verify(trustBase, requestId_{SIDE_A, V}) == OK +assert respB.inclusionProof.verify(trustBase, requestId_{SIDE_B, V}) == OK + +ctA = respA.inclusionProof.transactionHash.data // raw 32-byte digest +ctB = respB.inclusionProof.transactionHash.data + +xorKeyA = H(xorSeed || [SIDE_A] || be32(V) || "xor") +xorKeyB = H(xorSeed || [SIDE_B] || be32(V) || "xor") + +partA = xor(ctA, xorKeyA) +partB = xor(ctB, xorKeyB) + +full = partA || partB // 64 bytes + +cidLen = full[0] +if cidLen < 1 or cidLen > CID_MAX_BYTES: + raise AGGREGATOR_POINTER_CORRUPT + +cidBytes = full[1 .. 1 + cidLen) + +// Validate as a well-formed CID (multibase/multihash/codec). +if not isValidCid(cidBytes): + raise AGGREGATOR_POINTER_CORRUPT + +return { cid: cidBytes, version: V } +``` + +The CID parser used by `isValidCid` MUST bound all reads to the provided `cidBytes` slice, reject malformed varints, and accept only the codecs supported by the upstream `profile/ipfs-client.ts verifyCidMatchesBytes` (in practice: sha2-256 multihashes; expand as the upstream expands). + +**W2 — HTTPS-only gateway pool.** IPFS gateway URLs in the SDK's shipped configuration MUST use the HTTPS scheme. HTTP gateways MUST NOT be included in the multi-gateway fetch pool. Implementations MAY allow a user-configurable override for local/test deployments, gated behind an explicit capability flag `allowInsecureGateways: true` with a prominent startup warning. + +**Post-decode invariant (C4 / H10 — CAR fetch caps).** The resolved CID MUST be fetched via an IPFS client that enforces `MAX_CAR_BYTES` (100 MiB) and progress-rate timeouts (see H10 below). If caps are exceeded, the client MUST raise `AGGREGATOR_POINTER_CAR_TOO_LARGE` or `AGGREGATOR_POINTER_CAR_FETCH_TIMEOUT` respectively. The pointer layer treats these as recovery failures; the caller MAY choose to abort recovery or to fetch from a different gateway, but MUST NOT silently advance `localVersion` past an unfetchable bundle. See §10.7 for the related "CAR unavailable" persistent state. + +**H10 — Progress-rate CAR fetch timeout.** The earlier single-shot `MAX_CAR_FETCH_MS = 60s` timeout aborted legitimate slow-network fetches. r3.3 replaces it with progress-rate semantics. A CAR fetch aborts if ANY of the following hold: + +1. Initial response headers not received within `MAX_CAR_FETCH_INITIAL_RESPONSE_MS` (10 s). +2. No bytes received for `MAX_CAR_FETCH_STALL_MS` (30 s) after any previous byte. +3. Total elapsed time exceeds `MAX_CAR_FETCH_TOTAL_MS` (5 min) including all retries. +4. Total bytes received exceed `MAX_CAR_BYTES` (100 MiB). + +Implementations MUST support HTTP Range (`bytes=N-`) requests: on stall or transient failure, retry from the last successfully-received byte offset rather than starting over. The retry budget for resume attempts is `MAX_CAR_FETCH_RETRY = 3` per gateway with exponential backoff based on `MAX_CAR_FETCH_RETRY_BACKOFF_BASE_MS`. + +Implementations MUST NOT rely on `Content-Length` header for size verification. All size enforcement is streaming byte-count. + +`Content-Encoding: gzip | deflate | br` MUST be rejected on CAR responses (CAR format is already efficiently binary-encoded; compression adds only attack surface). A gateway returning `Content-Encoding` triggers `AGGREGATOR_POINTER_CAR_UNEXPECTED_ENCODING`. + +**Streaming byte-count enforcement (D6 — MANDATORY).** Implementers MUST enforce `MAX_CAR_BYTES` via a **streaming byte-count on the response body**, independently of any `Content-Length` header supplied by the gateway. The byte count MUST abort the underlying socket / reader within one additional chunk of exceeding `MAX_CAR_BYTES` — i.e., the implementation MUST NOT buffer an entire oversized response before checking the cap. + +Implementations MUST NOT rely solely on `Content-Length` headers for size verification. A malicious gateway can set a small `Content-Length` and stream arbitrary amounts of data beyond it; clients that trust the header are vulnerable to memory-exhaustion DoS. Correct implementations therefore: + +1. Initialize a running byte counter to zero before beginning the response read loop. +2. Increment the counter by `chunk.length` after each chunk read. +3. If `counter > MAX_CAR_BYTES`, abort the socket (close reader, release resources) and raise `AGGREGATOR_POINTER_CAR_TOO_LARGE` within one additional chunk of the overflow. +4. Enforce the progress-rate timers from H10 independently of any server-supplied hint. + +The `Content-Length` header MAY be used as an early-reject optimization (if `Content-Length > MAX_CAR_BYTES`, abort immediately before reading any body) but MUST NOT be used as the sole cap enforcement. + +--- + +## 9.

With jittered exponential backoff (§7.4), five attempts give roughly `250 + 500 + 1000 + 2000 + 4000 = 7.75 s` mean wall-clock backoff before `AGGREGATOR_POINTER_RETRY_EXHAUSTED`. Beyond that, pathological multi-device contention is assumed and requires operator or UX intervention. + +--- + +## 10. Failure Modes + +### 10.1 Partial publish (one side accepted, one side failed) + +All retryable sub-cases (see §7.3 outcome matrix) re-submit the **same `(v, side)` commitment** — same `requestId`, same `transactionHash`, same `authenticator` bytes. This is safe because: + +- `requestId_{side, v}` is a deterministic function of `(signingPubKey, stateHashDigest_{side, v})` — both fixed for a given `(v, side)`. +- `transactionHash_{side, v}` is `ctSide = xor(partSide, xorKey_{side, v})` — fixed once `(cidBytes, v)` are fixed, thanks to deterministic padding (§4.6). +- The aggregator is write-once keyed by `requestId`, so retry either succeeds (first delivery lost in flight) or returns `REQUEST_ID_EXISTS` (first delivery landed) — both are idempotent-success outcomes. + +Bounded by `PUBLISH_RETRY_BUDGET` with backoff per §7.4. + +> **MUST NOT:** under any retryable outcome, abandon `v` and skip to `v + 1`. Skipping is permitted ONLY for non-retryable protocol errors (`AUTHENTICATOR_VERIFICATION_FAILED`, `REQUEST_ID_MISMATCH`) that conclusively invalidate the submission. Skipping otherwise leaks orphan leaves and wastes version slots. + +### 10.2 Aggregator unreachable during recovery (MANDATORY) + +**Scenario.** `initialize()` could not reach the aggregator. Recovery returned no information — neither "no pointer at v=1" (exclusion) nor a discovered `V_true`. Subsequently, the local OpLog accumulates user-originated writes. + +**Behavior.** The wallet MUST BLOCK the next publish until one of the reachability outcomes listed under "CLEAR on" below is achieved. Proceeding to publish without reconciliation risks silently forking the OpLog across devices. + +**10.2.1 Persistent state.** BLOCKED is a per-wallet persistent boolean, so it survives process restarts and survives across machines sharing the wallet: + +``` +BLOCKED_FLAG_KEY = "profile.pointer.blocked." + hex(signingPubKey) // see §3 +``` + +Value: boolean. An absent key is equivalent to `false`. + +Implementations MUST expose this state via the `AGGREGATOR_POINTER_UNREACHABLE_RECOVERY_BLOCKED` error code (§12) on any publish attempt while BLOCKED, AND via the `isPublishBlocked()` query (§13). + +**10.2.2 SET on (entry conditions).** SET BLOCKED when ALL of the following hold: + +1. `initialize()` — or any subsequent reconciliation pass — attempts to reach the aggregator for recovery; +2. the transport error is **categorical**: network timeout, connection refused, DNS failure, TLS error (or equivalent). A non-categorical error (e.g., 5xx that may retry-succeed) MUST NOT set BLOCKED on first occurrence; +3. the local OpLog contains **at least one user-originated write** (see 10.2.3); +4. at least one retry with exponential backoff has already been attempted AND failed (to avoid flapping on single transient failures). + +Additionally, re-SET BLOCKED (reentry) when a publish attempt fails with `AGGREGATOR_POINTER_NETWORK_ERROR` whose error category matches the transport-categorical list in (2). + +**10.2.3 User-originated write definition.** An OpLog entry is *user-originated* iff its `originated` metadata tag equals `'user'`. OpLog writers MUST stamp each entry they author with one of: + +- `'user'` — the entry reflects a deliberate user action (token send, token receive, nametag register, DM send, invoice mint, invoice pay, swap propose/accept/deposit, etc.). These entries COUNT for the §10.2.2 condition (3). +- `'system'` — the entry is an SDK-internal bookkeeping write (session receipt, last-opened timestamp, cache index refresh, etc.). These do NOT count. +- `'replicated'` — the entry arrived via OrbitDB gossipsub or Nostr ingest from a remote peer. These do NOT count. + +The `originated` tag MUST be stamped at write time by the module authoring the entry; recipients of replicated entries MUST NOT mutate it. A missing or malformed `originated` tag on a locally-signed entry MUST be treated conservatively as `'user'` to fail closed (i.e., so a forgotten stamp cannot silently disable BLOCKED). + +> **Note on the prior `signedBy` rule (r3).** The earlier "`entry.signedBy == localSigningPubKey`" heuristic was ambiguous in two directions: (i) a session-receipt write signed by the chain key counts as user-originated under that rule and spuriously SETs BLOCKED; (ii) a "touch" write that isn't signed at all slips past and BLOCKED never SETs even though the user authored a visible action. The `originated` tag is orthogonal to `signedBy` — system-authored entries MAY still be signed by `localSigningPubKey`. Implementations migrating from r3 MUST stamp all emitted entries before C6 ships. + +This distinction is load-bearing: replicated entries from other devices do not themselves justify blocking, because their author's device is responsible for publishing its own pointer advance. + +**Semantic re-validation (D5).** The stamped `originated` tag is caller-asserted and therefore potentially forgeable by a malicious writer who stamps `'system'` on a token-send entry to silently disarm BLOCKED. To close this bypass, recipients MUST re-validate the stamped `originated` tag against the entry's OpLog type: + +- Entries whose type is in the **known user-action set** — `token_send`, `token_receive`, `nametag_register`, `dm_send`, `invoice_mint`, `invoice_pay`, `swap_propose`, `swap_accept`, `swap_deposit`, and any future member of this set that modules add — MUST have `originated = 'user'` regardless of the stamped value. Any other tag on a user-action entry MUST be rejected as `SECURITY_ORIGIN_MISMATCH` and MUST NOT be replicated further. +- Entries whose type is in the **known system set** — `session_receipt`, `cache_index`, `last_opened_ts` — MUST have `originated = 'system'` regardless of the stamped value. +- Entries of an **unknown type** are handled per the fail-closed rule above: missing / malformed / unknown ⇒ treated conservatively as `'user'`. + +This re-validation runs at two points: (i) on every locally-authored write, before durable persistence; (ii) on every replicated write, before the replica is accepted into the local OpLog. The check is byte-cheap (string-equality on the entry type) and closes the tag-forgery bypass. + +**§10.2.3.1 Migration — stamping existing OpLog writers (W11).** + +Every module that writes OpLog entries MUST stamp the `originated` tag. The following modules are affected in the current Sphere SDK: + +- `modules/payments/PaymentsModule.ts`: `token_send`, `token_receive`, `nametag_register`, transfer events → `'user'`. +- `modules/accounting/AccountingModule.ts`: `invoice_mint`, `invoice_pay`, `invoice_close` → `'user'`. +- `modules/swap/SwapModule.ts`: `swap_propose`, `swap_accept`, `swap_deposit`, payout → `'user'`. +- `modules/communications/CommunicationsModule.ts`: `dm_send` → `'user'`; `dm_receive` → `'replicated'` (receiver stamps as replicated regardless of the sender's stamp). +- `profile-token-storage-provider.ts flushToIpfs`: batch bundle events → `'system'`. +- Any session / cache / index writes → `'system'`. + +The implementation PR MUST update all listed modules atomically with the pointer layer. Deploying the pointer layer without the writer updates leaves BLOCKED state semantically inert: untagged entries default to `'user'` per the fail-closed rule above, causing spurious BLOCKED on every system write. + +**10.2.4 CLEAR on (exit conditions).** CLEAR BLOCKED only after EITHER: + +(a) A trustlessly-verified **exclusion** proof for `requestId_{A, 1}` AND `requestId_{B, 1}` — i.e., `PATH_NOT_INCLUDED` under `InclusionProof.verify(trustBase, ...)`. Applies ONLY when `localVersion == 0` (wallets that have never successfully published). OR + +(b) A successful `recoverLatest()` that yields `V_true > 0`, fetches the CID from IPFS, AND merges the remote bundle into the local OpLog (per §9.2 / Profile layer). + +Clearing on any OTHER condition — reachability-only probes, user preference changes, UI "dismiss" actions — MUST NOT happen unless the explicit operator override (10.2.5) is invoked. + +**10.2.5 User override protocol (optional).** For wallets in permanent-aggregator-outage scenarios (regional outage, deprecated testnet, air-gapped forensic recovery), implementations MAY expose a user-confirmed override. The override MUST: + +- Be opt-in **per-call** (not a persistent setting; each bypass is an explicit user action). +- Present a clear warning along the lines of: "Publishing without aggregator verification risks overwriting legitimate remote history from other devices." +- Emit telemetry `pointer:publish_override_used { version, reason }` (PII-free). +- Be gated behind a capability check — for instance, only available when a `allowUnverifiedOverride` flag is set at Sphere-init time, so naive consumers cannot stumble into it. + +v1 implementations MAY omit the override entirely and accept permanent read-only mode until the aggregator is reachable again. The override is explicitly NOT required for v1 sign-off. + +**10.2.6 Deleted in r3.2.** The r3.1 rule "SET BLOCKED on fresh-install corrupt-payload at cold start" is superseded by the valid-version-continuity rule (§10.3). Corrupt versions are SKIPPED during discovery (§8.2 Phase 3) rather than treated as MITM signals. Any remaining references to §10.2.6 elsewhere in this spec should be read as references to §10.3. + +### 10.3 Malformed recovered payload — valid-version continuity (D1, H1-refined) + +A XOR-decoded payload that fails length-prefix bounds, `isValidCid`, or CAR deserialization — or whose fetched CAR bytes fail content-address verification (CID hash ≠ bytes digest) — is `SEMANTICALLY_INVALID` in the H1 classification and is NOT treated as a MITM signal. Such versions are permanent SMT residue that the pointer layer **semantically ignores**. + +**Reconciliation with §10.7 (H1).** A version whose CAR cannot be fetched due to transient IPFS gateway outage is DIFFERENT: it is classified `TRANSIENT_UNAVAILABLE`, NOT `SEMANTICALLY_INVALID`, and Phase 3 DOES NOT walk past it. `TRANSIENT_UNAVAILABLE` propagates up as `AGGREGATOR_POINTER_CAR_UNAVAILABLE` so §10.7 handles it correctly: the wallet waits for gateways to recover, or follows the `acceptCarLoss()` protocol in §10.7.1. + +**Discovery rule.** `SEMANTICALLY_INVALID` versions are SKIPPED during discovery (§8.2 Phase 3 walk-back). The pointer layer considers the latest VALID version authoritative. `TRANSIENT_UNAVAILABLE` versions are NOT skipped; they surface up. + +**Publish rule.** Publishing a NEW valid version at `latest_valid_V + 1` is legitimate and does NOT require resolving the intermediate corrupt versions. The next legitimate publisher simply bumps `localVersion` from the latest valid version and proceeds. Each client performs valid-version continuity independently; **no inter-client coordination is needed**. + +**Error rule.** `AGGREGATOR_POINTER_CORRUPT` is raised only by the caller of `recoverLatest()` when the caller explicitly asked for the decoded payload at a specific corrupt version (e.g., a forensic diagnostic path). Ordinary discovery silently skips corrupt versions; it does NOT surface `AGGREGATOR_POINTER_CORRUPT` per-skip. Each skip MAY emit `pointer:discover_corrupt_skipped { version }` for telemetry visibility. + +**Implementation note.** This design accepts that corrupt versions MAY exist in the aggregator SMT — whether from buggy prior clients, aborted mid-migration publishes, transient gateway-level CAR corruption that later becomes valid as other gateways heal, or adversarial grinding by a publisher who has access to the wallet's `pointerSecret` (infeasible for an external attacker). They are permanent SMT residue but semantically ignored. The bounded walk-back (`DISCOVERY_CORRUPT_WALKBACK`) protects against pathological streaks via §10.8. + +Possible root causes for an observed corrupt version: + +- Key derivation drift between publisher and recoverer (library version skew in HKDF or SigningService). +- Wrong mnemonic imported (pointer decryption produces garbage; length prefix happens to be "valid-looking" but CID parse fails). +- Publisher violated §7.1 and reused `(v)` across two different CIDs — in which case both ciphertexts are now mutually recoverable by an observer (see §11). +- A prior client crashed mid-publish in a way that bypassed the §7.1 marker discipline (e.g., on a storage backend that silently violated the durability contract). +- Transient CAR gateway-level data corruption at fetch time (may self-heal; re-running discovery later MAY return a now-valid version). + +### 10.4 CID too large + +`cidLen > CID_MAX_BYTES` → reject at publish with `AGGREGATOR_POINTER_CID_TOO_LARGE`. A three-commitment extension is future work (`ARCHITECTURE §12`). + +### 10.5 Version overflow + +`v > VERSION_MAX` → reject at publish with `AGGREGATOR_POINTER_VERSION_OUT_OF_RANGE`. At `2^31 − 1`, even at one publish per second, this is ~68 years per wallet. + +### 10.6 Aggregator-signed false exclusion + +A malicious aggregator could return an exclusion proof for a `requestId` it previously accepted. Defense: `InclusionProof.verify(trustBase, ...)` roots the answer in the `RootTrustBase`. A forged exclusion requires forging the trust base, which is out of scope for this layer (assumed defended by BFT anchoring at L2/L1). + +For deployments wanting stronger guarantees, cross-check against multiple aggregator mirrors (future work, §12 of arch doc). + +### 10.7 CAR unavailable after successful recovery + +**Scenario.** After Phase 2 discovery returns a `V_true > 0` AND the CID decoded in §8.5 passes `isValidCid` AND `InclusionProof.verify(trustBase, ...)` returned `OK` for both sides, the caller invokes `fetchFromIpfs(cid)`. All configured IPFS gateways return 404 / unreachable / 5xx / time out under the H10 progress-rate budget. The CID is provably pinned at `V_true` by a trustlessly-verified inclusion proof, but the bundle bytes are not retrievable right now. + +**Behavior.** The pointer layer MUST: + +1. Raise `AGGREGATOR_POINTER_CAR_UNAVAILABLE` to the caller. +2. NOT advance `localVersion`. Treat `V_true` as known-but-uningested. +3. Refuse all subsequent `publish()` calls until EITHER the CAR becomes fetchable on retry, OR the caller invokes the `acceptCarLoss(version)` protocol in §10.7.1 with full operator consent. +4. Emit a `pointer:recover_car_unavailable { version, cid }` event for UI surfacing. + +**Why this is distinct from §10.2 BLOCKED.** §10.2 BLOCKED covers "aggregator unreachable → can't discover `V_true`". §10.7 CAR-unavailable covers "aggregator reachable, `V_true` discovered and verified, but the IPFS bundle itself can't be fetched". Advancing `localVersion` past an unfetchable bundle would silently replace legitimate remote history the moment fetch becomes possible again — a data-loss path. The caller opts into that loss only through the §10.7.1 protocol below. + +### 10.7.1 `acceptCarLoss` discipline (H7) + +`acceptCarLoss(version)` MUST NOT silently advance `localVersion`. The earlier v3.2 semantics ("advance localVersion past unfetchable bundle") could lose tokens that existed ONLY in the lost bundle. The H7 protocol closes this gap: + +1. **Capability gate.** Requires `Sphere.init({ allowOperatorOverrides: true })`. Naïve consumers cannot stumble into data loss. +2. **Prior persistent-retry exhaustion (wall-clock enforced).** At least `CAR_FETCH_PERSISTENT_RETRY_ATTEMPTS` (= 12) attempts across ALL configured gateways at 1-hour intervals over `CAR_FETCH_PERSISTENT_TOTAL_DURATION_MS` (= 24 h) must have elapsed. Implementations MUST enforce the wall-clock duration by persisting attempt timestamps to local storage so the duration is preserved across restarts. +3. **Peer-availability check.** Before advancing, emit `pointer:car_loss_pending { version, retriesRemaining, peerDiscoveryActive }` and poll OrbitDB gossipsub / Nostr for responders advertising this wallet's bundle for `POINTER_PEER_DISCOVERY_MS` (= 10 min). If ANY peer responds with a matching bundle, the CAR is NOT definitively lost; ABORT `acceptCarLoss` with `pointer:car_loss_aborted_peer_found { version, peer }` and resume fetch attempts. +4. **MANDATORY republish BEFORE advance.** On confirmed total unavailability, the wallet MUST IMMEDIATELY republish its current local OpLog state as a fresh bundle at `max(localVersion, version) + 1`, BEFORE advancing past `version`. This closes the "tokens only in the lost bundle" gap: if any local OpLog entries exist that weren't in the lost bundle, they are anchored in the new publish. If no new OpLog entries exist, an empty republish still establishes a recovery point. +5. **Advance only after republish.** Only AFTER the republish succeeds does `localVersion` advance to the republished version. +6. **Telemetry.** Emit `pointer:car_loss_accepted { version, republishedCID, republishedAt }`. + +**UI requirement.** The override MUST be presented to the user with the warning: *"Tokens added on other devices that only exist in the lost bundle will be permanently unrecoverable from this device. Consider waiting for network recovery or checking if other devices have this data."* + +### 10.8 Recovery bail on corrupt streak (D1) + +If §8.2 Phase 3 walk-back encounters `DISCOVERY_CORRUPT_WALKBACK` consecutive corrupt versions without finding a valid one, the client raises `AGGREGATOR_POINTER_CORRUPT_STREAK`. + +This is a **distinct** error from `AGGREGATOR_POINTER_CORRUPT`. It indicates either: + +(a) a pathological sequence of consecutive prior-client bugs (e.g., an old SDK release shipped with a broken encoder and every publish from that release is corrupt); OR + +(b) an adversary grinding garbage at the wallet's `requestId` space — possible only if the adversary has `pointerSecret`, which is computationally infeasible for any external attacker under the HKDF-SHA256 security argument (§11.1). + +**Recovery path.** The user MAY invoke the `acceptCorruptStreak(walkbackLimit?)` API (§13) which raises the walkback ceiling for a single recovery attempt, capped at an implementation-defined safety ceiling (e.g., 4096). Each use is audited via `pointer:corrupt_streak_override_used { walkbackLimit }` telemetry. + +**Why not SET BLOCKED on corrupt streak.** Unlike §10.2 (aggregator-unreachable) and the deleted r3.1 §10.2.6 rule, a long corrupt streak is not a MITM signal — MITM defenses now live entirely in §8.4 (multi-mirror TOFU) and §8.1 (trustless `InclusionProof.verify`). A legitimate mnemonic holder who has NOT been MITM'd but who is staring at a corrupt-heavy OpLog can progress past it by either accepting the streak and continuing discovery, or by publishing a new valid version (valid-version continuity, §10.3) and letting future recovery anchor on that new valid version instead. + +**Interaction with publish.** `AGGREGATOR_POINTER_CORRUPT_STREAK` does NOT SET BLOCKED. A caller who chose to accept the streak and recover successfully can publish normally from `latest_valid_V + 1`. A caller who declines to accept the streak remains in a read-only state but MAY still publish — the next legitimate publish at `localVersion + 1` will itself become the new latest-valid version and will anchor future recoveries by other devices. + +--- + +## 11. Security Considerations + +1. **Subkey separation.** `signingSeed`, `xorSeed`, `padSeed` are independent HKDF outputs from `pointerSecret` with distinct info strings (§4.2). Compromise of any single subkey does not compromise the others. + +2. **One-time-pad discipline.** Each `xorKey_{side, v}` is used on exactly one 32-byte plaintext half. Reuse would allow `xor(ct1, ct2) = xor(pt1, pt2)`, trivially recovering plaintext. The scheme enforces uniqueness by binding `xorKey` to `be32(v)`. The `pending_version` marker (§7.1) additionally prevents a crashed publisher from reusing `v` with a *different* plaintext after restart. + +3. **Deterministic padding.** `paddingBytes_v` is an HKDF-Expand output from `padSeed` — an internal secret. To an observer without `padSeed`, the padding is computationally indistinguishable from uniform random. Determinism is strictly a benefit for idempotent crash-retry: it removes the need to persist a CSPRNG seed across restarts. + +4. **Pubkey pseudonymity, not anonymity.** `signingPubKey` is stable across all versions and both sides for a given wallet. The aggregator can cluster "all commitments signed by this key are from the same entity." It cannot link `signingPubKey` to `walletPrivateKey` or to the wallet's chain pubkey (secret-derived via HKDF). G2 (from the arch doc) is therefore pseudonymous-per-wallet, not fully unlinkable across a wallet's own commits. Full anonymity (throwaway `signingPubKey` per version) is deferred future work. + +5. **Trustless proof verification (mandatory).** Every inclusion / exclusion claim the wallet acts on MUST be verified via `InclusionProof.verify(trustBase, requestId)` before being trusted. `trustBase` is the SDK-bundled `RootTrustBase` shared with L4 (§8.4, §8.4.2). The trust root is therefore the SDK bundle itself; supply-chain compromise of the bundle is the residual risk, planned to be closed by L1-alpha-anchored trust fingerprinting (v2 — see `PROFILE-AGGREGATOR-POINTER-ARCHITECTURE.md §12`). + +6. **Algorithm tag visible.** The `HashAlgorithm.SHA256` tag (`[0x00, 0x00]`) is visible in both `stateHash.imprint` and `transactionHash.imprint` published to the SMT. Because every ordinary L4 commitment uses the same tag, this does not distinguish pointer commitments. + +7. **CID parser hardening.** The decoder MUST bound reads to the 64-byte plaintext buffer, reject malformed varints, and accept only sha2-256 multihashes (aligned with `profile/ipfs-client.ts verifyCidMatchesBytes`). A permissive parser is a denial-of-service vector. + +8. **No replay surface.** The aggregator rejects duplicate `requestId`s. A replay of our own commitment returns `REQUEST_ID_EXISTS`, treated as idempotent-success (§7.3, §10.1). + +9. **No revocation.** Once `v` is committed, it is permanent. Recovery returns the latest version; prior versions are ignored. OrbitDB CRDT on the OpLog side handles content-level conflict resolution. + +10. **Timing side channels.** The aggregator observes publish and probe cadence. "This wallet has approximately `V` versions" is inferable from probe patterns; "this wallet is active now" is inferable from commit arrivals. Not mitigated at this layer. See `ARCHITECTURE §12`. + + Additionally, **discovery probe-sequence fingerprint (C7).** The sequence of `(v, side)` request-IDs probed during recovery (§8.2 Phase 1 exponential + Phase 2 binary-search + Phase 3 walk-back) is a deterministic function of `(V_true, localVersion, {corrupt-version set})`. An aggregator operator or on-path observer who logs probe IDs across sessions can correlate two sessions from the same wallet as "same probe signature" even when the wallet uses different IP addresses, Tor exit nodes, or mirror rotations. This is a stronger clustering signal than `signingPubKey` alone (which already leaks across A/B at the same `v`; see bullet 4 above) because it ties together sessions separated in time. Mitigations (deferred to v2): (a) randomize the Phase 1 exponential base — e.g., start `hi = DISCOVERY_INITIAL_VERSION + random_jitter()` where `random_jitter` is a uniform draw with variance comparable to the expected bin-search depth; (b) insert decoy probes at random versions during discovery; (c) probe via a small anonymity set of pointer-layer identities rotated per session. None of these are required for v1 ship; document as a known limitation that the §13 `getProbeFingerprint()` API may surface to UIs. + +11. **Retry-rejected ciphertexts are sensitive (H14 — achievable target).** A ciphertext computed for `(v, side)` that the wallet submits and the aggregator rejects with `REQUEST_ID_EXISTS` (because another device's commit landed first) shares `xorKey_{side, v}` with the committed ciphertext. An attacker who captures BOTH the rejected ciphertext AND the committed ciphertext can XOR them to reveal the plaintext differential. + + Implementations SHOULD minimize in-memory residence of secret material derived from the mnemonic. JavaScript / TypeScript runtimes offer no guaranteed memory zeroization (GC-managed memory, move-on-minor-GC, immutable strings), so the requirements below are scoped to what is actually achievable at the SDK layer: + + (a) **Re-derivation discipline — primary defense (normative).** The ciphertext for each retry MUST be freshly derived from the deterministic key material (`xorKey_{side, v}`, `paddingBytes_v`) rather than retained across retries. Deterministic padding (§4.6) guarantees byte-identity across re-derivations, so the aggregator's write-once `requestId` semantics still yield idempotence. Re-derivation is computationally cheap (two HKDF-Expand + one XOR per side) and closes the OTP-reuse window deterministically. + + (b) **Caller-owned buffer zeroization — best effort.** Implementations SHOULD zero-fill `Uint8Array` buffers the CALLER owns (e.g., intermediate ciphertext buffers before they're handed to the SDK) immediately after use. SDK-internal copies (`DataHash._data`, `Authenticator.signature`, `Signature.bytes`, JSON-RPC transport hex strings) are OUT OF SCOPE for this spec — they are not reachable from the caller and are not reliably zeroizable in JS. + + (c) **Runtime-provided protections — recommended where available.** Node.js implementations MAY use `Buffer.allocUnsafeSlow` + `sodium_memzero` for seed-material storage when running in a native-extension-enabled environment. Browsers have no equivalent; accept this limitation. + + (d) **Secret-value denylist (normative).** The following values MUST NOT appear in any log, telemetry event, error message, stack trace, or persistent storage outside the encryption module boundary: + - `pointerSecret` + - `signingSeed`, `xorSeed`, `padSeed` + - `signingService.privateKey` + - `walletPrivateKey` (the master key itself) + - retry-rejected ciphertext bytes (may leak `xorKey` via differential analysis per the opening paragraph) + Ciphertext-containing structures MUST be excluded from any serializer used for log emission. This rule applies at ALL verbosity levels including debug/trace in CI or development builds. + + (e) **Wrapper type (recommended).** Implementations MAY wrap secret-material in a `SecretKey` type whose `toString` / `toJSON` / `util.inspect` hooks return a redaction marker rather than the underlying bytes. + + **Rationale.** The r3.1 "zeroize backing buffer immediately" language was not achievable given SDK-internal copies and immutable hex strings in JS. The H14 rewrite makes (a) the primary defense (re-derivation per retry, cryptographically sound) and treats (b)-(c) as defense-in-depth best effort. The full hardening target — guaranteed memory zeroization requiring native-memory primitives — is deferred to future work. + +12. **Denylisted keys (C8).** Implementations SHOULD maintain a denylist of well-known test keys and refuse to bind the pointer layer to any such key in non-test networks. The denylist MUST include at minimum the §14.1 canonical vector (`walletPrivateKey = 0x01 × 32`, checked via `SHA-256(walletPrivateKey) == SHA-256(0x01 × 32)` to avoid storing the raw scalar in the denylist itself). The check occurs at `Profile.init()` time, before any pointer-layer derivation runs, and fires only when `config.network != 'test-vectors'`. Implementations MAY extend the denylist with other well-known public test keys (Bitcoin "1 × 32" vectors, secp256k1 test-suite vectors, etc.) as they become aware of them. A positive denylist hit MUST abort init with a distinct, non-ignorable error; falling back to a warning is explicitly NOT permitted. + + **Note on defense-in-depth (W9).** The client-side runtime check is a policy boundary, not a cryptographic one. An attacker who compiles without the check (or disables it via debugger) can still use the denylisted key. Aggregator-side enforcement — rejecting submissions signed by known test-key pubkeys on non-test networks — is the only cryptographically binding defense and is tracked in §11.13 item (iv). The aggregator team has NOT yet committed to this check; until then, client-side enforcement is defense-in-depth only. + +13. **Residual risks documented as trade-offs (v2 work) (D10).** Revision 3.2 fixes all objective bugs surfaced by the r3.1 steelman reviews, but the following trade-offs remain. They are NOT bugs; they are consequences of the scheme's design choices that would require deeper changes (L1 anchoring, governance, protocol redesign) to resolve and are deferred to v2. + + (i) **Bundled trust base = centralized trust root.** v1 Sphere ships with `RootTrustBase` embedded in `assets/trustbase/.ts` (§8.4). This same bundle is consumed by L4. Supply-chain compromise of an SDK release therefore lets an attacker forge proofs that verify against their own trust base on every downstream wallet simultaneously. **v2 work:** anchor `RootTrustBase` fingerprints to the ALPHA (L1) chain (e.g., committed in a coinbase OP_RETURN or governance-signed record) so wallets can verify the bundled trust base matches an out-of-band L1 attestation at init time. This also unblocks runtime-fetched trust-base refresh, at which point a multi-mirror TOFU cross-check (≥ 2 independently-addressed aggregator mirrors returning byte-identical trust bases) becomes a meaningful additional defense and is re-introduced alongside it. See `PROFILE-AGGREGATOR-POINTER-ARCHITECTURE.md §12`. + + (ii) **Multi-mirror TOFU + runtime-fetched trust-base integrity deferred to v2.** v1 has no runtime trust-base fetch to defend, so multi-mirror cross-check, cert pinning, CA/IP diversity, and mirror-list integrity (all removed in v3.4) are not applicable. They become meaningful in v2 once the L1-anchored + runtime-refreshed trust-base model from (i) ships; at that point the availability trade-offs noted previously (DDoS-resistance of the mirror set, operator capability gates for single-mirror fallback) re-emerge and MUST be revisited. + + (iii) **Manual backup/restore across devices triggers `MARKER_CORRUPT`.** A legitimate user flow — copying `.profile/` state from device A (at `v = 2000`) to device B (at `v = 0`) — produces a marker on device B whose version gap exceeds `MARKER_MAX_JUMP = 1024`, triggering `AGGREGATOR_POINTER_MARKER_CORRUPT` (§7.1.4). Recovery IS available via `clearPendingMarker()` (§13) but implementations MUST surface UX guidance for backup-restore scenarios; a user without the guidance faces an opaque error. **v2 work:** on first-boot when the only persistent state is a mismatched marker (no `localVersion`, no OpLog entries, no other signals of a legitimate prior session), auto-call `clearPendingMarker()` and emit `pointer:marker_cleared { reason: 'auto_compacted' }`. + + (iv) **Denylist governance (C8 extension).** §11.12 requires runtime rejection of known test keys. v1 ships with a single hard-coded entry (the §14.1 canonical vector). There is no formal governance for adding entries as new public test keys become known. **v2 work:** define where the canonical denylist lives (in-SDK, IPNS-published, L1-anchored), how it versions (monotonic seq + signed root), how new entries propagate to shipped wallets (lazy check against a remote manifest at init time), and whether the list is signed by a release key, a multisig, or both. + + (v) **Corrupt streak as a legitimate-use DoS vector.** §10.8 bails with `AGGREGATOR_POINTER_CORRUPT_STREAK` after `DISCOVERY_CORRUPT_WALKBACK = 64` consecutive corrupt versions. A publisher who crashes-mid-publish at a high rate (≥ 64 consecutive times) produces a legitimate-use corrupt streak that legitimate recoverers then see. The user can `acceptCorruptStreak()` but this is a UX papercut. **v2 work:** distinguish crash-mid-publish residue from adversarial grinding via a fingerprint on the XOR-decoded plaintext (e.g., a short marker byte that publishers always include, so unmarked corrupt versions can be skipped at higher rates without raising the bail threshold). + +--- + +## 12.

(3) Normative user-facing warning text for `acceptCarLoss` (cross-ref §10.7.1), `acceptCorruptStreak`, `clearPendingMarker`. (4) Telemetry discipline: `pointer:pending_marker_cleared` added; all override telemetry MUST NOT contain secret material (§11.11(d)).

Executive Summary + +### 1.1 Goal + +This specification is the **formal proof-by-enumeration** that the Profile Aggregator Pointer Layer satisfies its north-star invariant: + +> **No tokens ever lost under any circumstances or race conditions.** + +Every scenario below is stated, evaluated against that invariant, and mapped to a concrete assertion that proves or disproves it. The test spec predates the implementation PR by design — no code is written until every red-boxed scenario in this document has a named owner, a fixture, and a pass criterion. + +### 1.2 Invariants Under Test + +| # | Invariant | Source | +|---|---|---| +| I-TC | **Token conservation.** Every token held by any device at time T is recoverable at time T' > T, from at least one device holding the wallet's mnemonic, regardless of crashes, network faults, or concurrent writers. | North star | +| I-VM | **Version monotonicity.** `localVersion` is non-decreasing over the wallet's lifetime. Committed versions are permanent. | SPEC §5.3 I-1 | +| I-DR | **Deterministic recovery.** Given the mnemonic alone and a reachable aggregator + IPFS, recovery produces a bit-identical inventory on any device. | SPEC §4–§8 | +| I-CS | **Crash safety.** Any publisher crash at any instruction boundary leaves no state that could cause OTP reuse, token loss, or silent fork across devices. | SPEC §7.1 / ARCH §7.2 | +| I-MDC | **Multi-device convergence.** K devices racing at the same `V` converge in `O(K)` publish attempts with zero token loss. | SPEC §9 / ARCH §8.5 | +| I-TV | **Trustless proof verification.** No inclusion or exclusion claim is acted upon without `InclusionProof.verify(trustBase, requestId)` returning OK. | SPEC §8.4 | +| I-TB | **Shared trust base.** The `RootTrustBase` used by the pointer layer is identically the instance used by L4. | SPEC §8.4.2 H6 | +| I-OT | **Originated-tag discipline.** Only `'user'`-tagged entries can trigger BLOCKED; semantic re-validation catches forged tags. | SPEC §10.2.3 | +| I-PC | **Proof Conservation (v2).** Every aggregator proof read (inclusion or non-inclusion) MUST be verified before trust. Token count invariant is checked after every scenario via `TokenConservationInvariant.assert()`. | SPEC §6.2 / §8.4, ARCH §6.5 | +| I-FX | **Fixture Isolation (v2).** Each test scenario's fixture is independent; no test depends on side effects from prior tests.

Tests where a finding's regression test is the PRIMARY purpose of the test case are marked in §4's "Primary" column. v2 adds explicit regression tests (H8-R, H14-R). (H3-R deleted in v2.2 per SPEC v3.4 embedded-trust-base amendments — H3 and H9 are v2 future work.) + +--- + +## 2. Test Taxonomy + +Sixteen categories (A–P). Each category starts with a one-paragraph rationale followed by enumerated scenarios. Scenario numbering is **stable** — test engineers cite scenarios by `` (e.g., `B5`, `M11`). + +### Category A — Happy Path Baselines + +**Rationale.** If the happy path is broken, everything downstream is noise. A suite of five scenarios exercises the undeviated flow: fresh wallet create, sequential publishes, CAR round-trip, per-wallet scoping, multi-address sharing. Every other category subtly depends on these five passing. + +| ID | Scenario | Preconditions | Actions | Expected | Success Criterion | +|---|---|---|---|---|---| +| **A1** | Fresh wallet → single publish → cold-start recovery on a second device returns the same tokens. | Fresh data dirs on two devices; shared mnemonic; aggregator + IPFS reachable. | Device A: `Sphere.init`, faucet a token, `publish`. Destroy A. Device B: `Sphere.import(mnemonic)`, wait for recovery. | Device B's OpLog contains the token. | `payments.getTokens().length === 1`; `balance === faucet amount`; no Nostr replay (B uses `createNoopTransport`). | +| **A2** | Sequential publishes at `v = 1..5` → discovery finds latest. | Device with Profile mode. | Send 5 tokens in sequence, each triggering a `flushToIpfs` + pointer publish. Destroy. Re-import. | Recovery probes converge to `v = 5` and fetches its CAR. | `localVersion === 5` after recovery; all 5 tokens present. | +| **A3** | CAR round-trip via IPFS (pin + fetch verification). | Two Unicity IPFS gateways reachable. | Publish at `v = 1` to gateway G1. Re-import on Device B using ONLY gateway G2. | CAR fetch from G2 succeeds; content-address verify passes. | `verifyCidMatchesBytes` returns true; no `AGGREGATOR_POINTER_CORRUPT`. | +| **A4** | Per-wallet scoping — two wallets on same device don't collide. | Two mnemonics, same `dataDir`. | `Sphere.init(wallet1)` → publish. `Sphere.switchToAddress(...)` is NOT used; this tests separate wallets. `Sphere.init(wallet2)` with a DIFFERENT mnemonic (separate Profile). | W1's pointer/marker/BLOCKED keys are namespaced by `hex(signingPubKey)` and do not overlap with W2's. | Both wallets publish independently; `PENDING_VERSION_KEY` keys are distinct; `BLOCKED_FLAG_KEY` keys are distinct; `MUTEX_KEY` keys are distinct. | +| **A5** | Multi-address within one wallet — one OpLog, one pointer chain. | One mnemonic, HD addresses `0` and `1`. | `switchToAddress(1)` → faucet → send → back to `0`. | All HD addresses under one mnemonic share ONE OpLog and ONE pointer chain (SPEC §5.2). | `localVersion` advances monotonically regardless of active address; `signingPubKey` is wallet-global, not per-address. | + +### Category B — Crash Safety (pending_version marker discipline) + +**Rationale.** The pending-version marker is the **load-bearing defense** against OTP reuse (SPEC §7.1, §11.2). A crash at any instruction boundary — marker-write, submit-A, submit-B, localVersion persist, marker-clear — must leave the wallet in a state that never reuses `(v, side, xorKey)` against a different plaintext. Eleven scenarios (B1–B11) enumerate the crash points and document the restart behavior. + +For each scenario: **Pre-state** (what's on disk before crash), **Crash trigger** (instruction at which SIGKILL fires), **Restart behavior** (what the publish code does on re-entry), **Expected outcome**, **Assertion**. + +| ID | Pre-state | Crash trigger | Restart behavior | Expected | Token-loss assertion | +|---|---|---|---|---|---| +| **B1** | `localVersion = k`; marker absent. | BEFORE marker write. | Recompute `v = k+1`; write fresh marker; proceed normally. | Ordinary publish at `v = k+1`; no residue. | `payments.getTokens()` unchanged; no SMT entry at any `v`. | +| **B2** | `localVersion = k`; marker `(k+1, cidHash_1)` written. | AFTER marker write, BEFORE submit A begins. | Marker present; H13 idempotent-retry: same v AND same cid → keep v, re-derive deterministic payload (§7.1.4). | Publish succeeds at `v = k+1` with byte-identical ctA/ctB. | `localVersion === k+1`; aggregator shows IDs at both sides. | +| **B3** | Submit A succeeded; marker intact. | AFTER submit A, BEFORE submit B begins. | Marker present, same cid. Re-submit A (returns `REQUEST_ID_EXISTS` idempotent-success per SPEC §7.3 row 2); submit B fresh. | Both sides committed at same `v`. | No OTP reuse detectable (ctA is byte-identical between attempts). | +| **B4** | Submit A succeeded; submit B in-flight (not acked). | AFTER submit A, AFTER submit B send but BEFORE ack. | Re-submit both: A → `REQUEST_ID_EXISTS`; B → either `SUCCESS` (lost ack) or `REQUEST_ID_EXISTS`; both treated as idempotent-success. | Both sides at `v = k+1`. | No double-commit at different version; no partial residue at `v = k+2`. | +| **B5** | Both sides committed at `v = k+1`; marker intact; `localVersion` NOT persisted. | AFTER both SUCCESS, BEFORE `localVersion` persist. | SPEC §7.3 row 4 — `REQUEST_ID_EXISTS` on both sides with marker match → idempotent replay → persist `localVersion = k+1`; clear marker. | `localVersion` reaches `k+1`; marker cleared. | No §9 reconciliation invoked (arch §7.3 bullet 2). | +| **B6** | `localVersion = k+1`; marker intact. | AFTER `localVersion` persist, BEFORE marker clear. | §7.1.4 stale branch: `previousEntry.v < currentLocalVersion` is false (equal), but §7.1.6 fallback — next publish sees `previousEntry.v == currentLocalVersion` → treat as stale and drop. | Next publish computes `v = k+2` fresh. | Marker auto-compacted; no spurious advance. | +| **B7** | Marker `(v = X, cidHash = H)`; current cidBytes hash to `H`. | Process restart. | **Idempotent replay (H13).** Same v AND same cidHash → retry deterministic payload; aggregator returns `REQUEST_ID_EXISTS` → treat as success. | No new version consumed; publish completes idempotently. | No OTP reuse; SPEC §7.1.4 rule verified. | +| **B8** | Marker `(v = X, cidHash = H)`; current cidBytes hash to `H' ≠ H`. | Process restart. | Rollback-safe bump (H13 / §7.1.4): `v := max(v, previousEntry.v) + 1`; persist fresh marker; submit at new v. | New publish at `v+1` with fresh keys. | OTP reuse impossible (fresh `(v+1, side)` → fresh xorKey). | +| **B9** | Marker `(v = X, ...)`; `currentLocalVersion = Y > X`. | Process restart. | §7.1.4 stale branch: `previousEntry.v < currentLocalVersion` → clear marker; proceed with current v. | Stale marker discarded; publish at `Y+1`. | No regression of `localVersion`; no OTP reuse. | +| **B10** | Marker `(v = 2^30, ...)`; `currentLocalVersion = 5`. | Process restart. | §7.1.4 tamper check: `previousEntry.v > currentLocalVersion + MARKER_MAX_JUMP (1024)` → raise `AGGREGATOR_POINTER_MARKER_CORRUPT`. | Publish refused; error surfaced; recovery via `clearPendingMarker()`. | No brick-via-single-write (SPEC §7.1.4 rationale). | +| **B11** | Marker file contains partial JSON / corrupt bytes. | Process restart. | Parser rejects; raises `AGGREGATOR_POINTER_MARKER_CORRUPT`. | Publish refused. `clearPendingMarker()` capability-gated recovery (W6): removes marker AND **SETs BLOCKED** to force re-verify. | No silent resume on corrupt marker; BLOCKED prevents immediate publish post-clear. | + +### Category C — Multi-Device Contention + +**Rationale.** Multi-device scenarios test the core race-safety property: when two devices publish concurrently to the same version, one wins (chosen deterministically by aggregator request-ID collision), the loser is notified synchronously, and both remain consistent. The outcomes are: one device's commit succeeds, the other learns of the collision, re-probes the aggregator, and bumps its version. No silent overwrites; no silent forks. + +| ID | Scenario | Fixture | Steps | Expected | Assertion | +|---|---|---|---|---|---| +| **C1** | Two devices publish simultaneously to `v = 1` → both request IDs collision → one `SUCCESS`, one `CONFLICT`. | `twoDeviceSync` at `v = 0`. | Device A and B both call `publishPointer(v=1, cid_A)` and `publishPointer(v=1, cid_B)` concurrently (race). | One receives `SUCCESS` (inclusive proof), one receives `REQUEST_ID_EXISTS` (conflict). Loser re-probes and finds `v = 1` occupied. | Loser bumps to `v = 2`; eventual consistency reached in `O(2)` attempts. No token loss; no fork. | +| **C2** | Device A wins at `v = 1` (cid_A included); Device B loses and re-probes. B re-derives `v = 2` and publishes cid_B; both converge. | Derived from C1 outcome. | Device B: re-probe confirms A's `v = 1`, then publish at `v = 2`. Device A: idle. Then both perform recovery from scratch. | Both devices independently recover both CIDs in order: `v = 1` (cid_A), `v = 2` (cid_B). | Token inventory identical on A and B. Causality preserved: cid_A before cid_B. | +| **C3** [parameterized by side ∈ {A, B}] | Side A/B submits at `v = K` while side B/A has already published `v = K+1` (version skew race). | `midLifecycle` on device D: `localVersion = 5` on D. Spawn two concurrent subscribers T1, T2 checking pointer state. | T1: reads `localVersion = 5`, bumps marker to `v = 6`. T2: concurrently reads stale `localVersion = 5` from cache, also bumps to `v = 6`. Both submit at `v = 6`. | Only one of two T1/T2 commit succeeds at `v = 6`. Loser observes collision and re-probes. | Marker compaction (§7.1.6): next publish on D sees no conflict; `localVersion === 6` final. | +| **C4** [parameterized by side ∈ {A, B}] | Partial publish: side A includes, side B times out mid-submit, then network recovers. Device retries side B at same `v`. | Fixture: `midLifecycle`. Inject network timeout on side B (aggregator mock delays >PUBLISH_REQUEST_TIMEOUT_MS). | Submit `v = K+1`: side A succeeds, side B times out. Retry: side B returns `AGGREGATOR_POINTER_TRANSIENT_UNAVAILABLE`. Automatic backoff + retry succeeds. | Both sides eventually included at `v = K+1`. Marker compacted; `localVersion` advanced. | No version bump; no OTP reuse; both sides at same `v`. | +| **C5** | Aggregator unreachable on recovery init → BLOCKED set → user resumes → aggregator recovers → BLOCKED cleared on next publish check. | Fixture: `freshWallet` with aggregator mocked unreachable. | (1) Init with unreachable aggregator → logs warning, proceeds without recovering pointer. (2) BLOCKED flag set (H1 closure). (3) Call `publish()` → refused with `AGGREGATOR_POINTER_BLOCKED_AWAITING_RECOVERY`. (4) Aggregator restored to reachable. (5) Call `publish()` → check aggregator connectivity → BLOCKED flag cleared → publish proceeds. | Step 3: publish rejected. Step 5: publish succeeds. BLOCKED flag transitions `true → false`. | No silent overwrite of remote history (the reason BLOCKED exists); user awareness enforced. | +| **C6** | **AMENDED v2.2:** Trust-base rotation mid-recovery under embedded-trust-base model (SPEC v3.4 §8.4). The wallet does NOT refresh the trust base at runtime; instead it detects epoch mismatch and halts. | Fixture: `midLifecycle` with mock aggregator. | Aggregator begins returning proofs against a new root (epoch N+1). Wallet's bundled `RootTrustBase` is at epoch N. Probe returns proof at epoch N+1. | Wallet detects epoch mismatch between aggregator response and embedded `RootTrustBase`. Recovery halts with `AGGREGATOR_POINTER_TRUST_BASE_STALE`; user is prompted to update SDK (v1 has no mid-session rotation). | No silent acceptance of unverified rotation; no token loss. Runtime rotation is v2 future work. | +| **C7** | Two devices attempt to `clearPendingMarker()` simultaneously (capability-gated, user-initiated). | Fixture: `blockedState`. | Device A and B both hold the mnemonic and both call `clearPendingMarker()`. | One succeeds and clears marker. Second sees no marker (idempotent no-op) and returns success. BLOCKED flag may still be set pending next aggregator check. | No corruption; no race on marker file. | +| **C8** | Conflict retries exceed budget; `AGGREGATOR_POINTER_RETRY_EXHAUSTED` surfaced. | Fixture: `midLifecycle`. Aggregator mock always returns conflict (`REQUEST_ID_EXISTS`) up to 5 consecutive retries. | Publish at `v = K+1`; aggregator rejects every side with conflict (rare pathological case). After 5 retries, publisher gives up. | Error `AGGREGATOR_POINTER_RETRY_EXHAUSTED` returned to caller. CAR is NOT cleaned up (already pinned; retry-friendly). | Next manual retry attempt succeeds if pathology clears. Token inventory unchanged (no publish took effect). | +| **C9** | Multi-device silent fork prevention: Device A and B both independently arrive at different cid for same `v` (e.g., due to OrbitDB merge conflict at user level). Pointer layer ensures only one is published; other is queued for `v = K+1`. | Fixture: `twoDeviceSync` at `v = K`. Both A and B perform identical faucet-and-consume locally, but due to nondeterministic CRDT merge, their OrbitDB arrives at different CID for the "same" logical snapshot. | Device A publishes first at `v = K+1` with `cidA`. Device B independently publishes (unaware of A) with `cidB`. B's publish races A's; B loses conflict at `v = K+1`. B re-probes, sees A's `cidA`, then bumps to `v = K+2` with its own `cidB`. | Both `cidA` and `cidB` eventually published (at `v = K+1` and `v = K+2`). On recovery, both CIDs are recovered and merged via OrbitDB JOIN rules (§10.4). | Token inventory is union of A and B (no loss). Causality: cidA precedes cidB. | +| **C10** | Crash during conflict retry: pending marker has `v = K+1`; second device already published at `v = K+1`. Wallet restarts during backoff sleep. | Fixture: `midLifecycle`. Marker `(K+1, cid_local)` written; submit A in-flight to aggregator. Meanwhile, Device B publishes same `v = K+1` with `cid_remote` (different content). Device A process crashes during backoff before retry. | Restart: marker still `(K+1, cid_local)`. Re-probe aggregator at `K+1` → finds `cid_remote` published. Recognize mismatch. Bump to `K+2`. | No OTP reuse. Publish proceeds at `K+2`. Device B's `cid_remote` at `K+1` is preserved. | Both CIDs recovered; no loss. | + +### Category D — Network Pathology + +**Rationale.** Network faults are transient but pervasive. D1–D18 test timeouts, latency spikes, partial packet loss, aggregator unreachability windows, IPFS gateway failures, Nostr relay disconnects, and malformed responses. Each must surface a correct error code (TRANSIENT_UNAVAILABLE vs. SEMANTICALLY_INVALID — critical for H1 closure) and trigger deterministic retry logic. + +| ID | Scenario | Impairment | Expected error code | Retry behavior | +|---|---|---|---|---| +| **D1** | Aggregator completely unreachable (no route / DNS fails). | Network: aggregator IP unreachable. | `AGGREGATOR_POINTER_NETWORK_ERROR` (transient). | Exponential backoff; infinite retries (capped per publish by PUBLISH_RETRY_BUDGET). | +| **D2a** | Aggregator responds slowly (+500ms latency spike, still within timeout) [parameterized variant A]. | Network: inject +500ms latency on `submitCommitment`. | `SUCCESS` (no timeout; latency transparent). | None (succeeds). | +| **D2b** | Aggregator responds slowly (latency pushes total time to timeout - 1ms, recovers) [parameterized variant B]. | Network: inject latency so total RTT approaches but does not exceed PUBLISH_REQUEST_TIMEOUT_MS. | `SUCCESS`. | None. | +| **D2c** | Aggregator responds slowly (latency exceeds timeout, request aborted) [parameterized variant C]. | Network: inject latency > PUBLISH_REQUEST_TIMEOUT_MS on submitCommitment. | `AGGREGATOR_POINTER_REQUEST_TIMEOUT` (transient). | Exponential backoff; retry after delay. | +| **D3a** | Aggregator packet loss on probe (getInclusionProof) [parameterized variant A]. | Network: drop 30% of packets to aggregator. | `AGGREGATOR_POINTER_TRANSIENT_UNAVAILABLE` (after retry budget exhausted per-request, W4 closure). | Per-request timeout + backoff; per-round recovery via re-probe. | +| **D3b** | Aggregator packet loss on submit (submitCommitment) [parameterized variant B]. | Network: drop 20% of packets to aggregator. | `AGGREGATOR_POINTER_TRANSIENT_UNAVAILABLE` or `SUCCESS` (non-deterministic, both acceptable). | Retry with backoff. On success, treat idempotently (SPEC §7.3). | +| **D3c** | Aggregator packet loss on trust-base fetch (H6 closure: separate trust-base query) [parameterized variant C]. | Network: drop 50% of packets on trust-base resolution RPC. | `AGGREGATOR_POINTER_UNTRUSTED_PROOF` if trust-base fetch fails (cannot verify); otherwise `SUCCESS` with cached trust base. | Retry trust-base fetch; fall back to last-known root if recent. | +| **D4** | IPFS gateway unreachable (CAR fetch fails). | Network: IPFS gateway IP unreachable. | Publish succeeds; CAR pinned to local IPFS. Recovery: on fetch, gateway unreachable → try next gateway in mirror list. | Retry on next gateway (W4 closure: per-gateway timeout). | +| **D5** | IPFS gateway slow (CAR fetch, partial response, stall). | Network: inject stall on CAR response stream (no bytes for 35 seconds, exceeding MAX_CAR_FETCH_STALL_MS). | On recovery: `AGGREGATOR_POINTER_CORRUPT_CAR` (stall exhaustion) → trigger persistent-retry loop (§10.7). | Persistent retry across gateways over 24 hours (CAR_FETCH_PERSISTENT_TOTAL_DURATION_MS). | +| **D6** | IPFS gateway returns partial CAR (truncated, fails content-address verification). | Network: IPFS returns first 10MB of 50MB CAR, then closes. | Publish succeeds. Recovery: fetch succeeds (no network error), but `verifyCidMatchesBytes` fails → `AGGREGATOR_POINTER_CORRUPT_CAR`. | Persistent retry loop (W7 closure) up to CAR_FETCH_PERSISTENT_RETRY_ATTEMPTS (12×). | +| **D7** | Nostr relay unreachable (nametag resolution for peer discovery, H3 closure). | Network: Nostr relay down. | Pointer layer succeeds (Nostr not required for pointer). Peer discovery (if attempted) gets `TRANSPORT_UNAVAILABLE`. | Fallback to manual address entry; no token loss. | +| **D8** | Aggregator returns malformed response (JSON parse error). | Aggregator: mock returns invalid JSON. | `AGGREGATOR_POINTER_PARSE_ERROR` (permanent, non-retryable). | No retry. | +| **D9** | Aggregator returns `AUTHENTICATOR_VERIFICATION_FAILED`. | Aggregator: mock rejects signature (simulated crypto error). | `AGGREGATOR_POINTER_AUTH_FAILED` (permanent). | No automatic retry (code defect). | +| **D10** | Aggregator returns `REQUEST_ID_MISMATCH`. | Aggregator: mock rejects request ID derivation. | `AGGREGATOR_POINTER_REQUEST_ID_MISMATCH` (permanent). | No automatic retry. | +| **D11a** | Slow-network RTT feasibility: worst-case observed p95 RTT × slowness multiplier stays within timeout budget (v2 new). | Measure: real testnet p95 + p99 RTT; compute `PUBLISH_REQUEST_TIMEOUT_MS / (measured p95 * retries)`. | Must be > 1.5× (safety margin). | Feasible; budget validates. | +| **D11b** | Slow-network RTT boundary test: inject RTT = PUBLISH_REQUEST_TIMEOUT_MS - 1 RTT unit. Verify completion. Then cross boundary; verify graceful timeout classification (v2 new). | Latency injection: set to timeout boundary ± delta. Run both sides of crossing. | At boundary-1: `SUCCESS`. At boundary: `REQUEST_TIMEOUT` (transient). | Backoff + retry succeeds. | +| **D12** | Trust-base fetch timeout (H6, W4). | IPFS gateway for trust-base slow; exceeds IPNS_RESOLVE_TIMEOUT_MS. | `AGGREGATOR_POINTER_UNTRUSTED_PROOF`. | Retry with fallback to cached root (if recent, per SPEC §8.4.2). | +| **D13** | Aggregator mirror returns `HTTP 503 Service Unavailable`. | Mock aggregator returns 503. | `AGGREGATOR_POINTER_TRANSIENT_UNAVAILABLE` (per HTTP semantics). | Retry on same mirror; switch to next mirror. | +| ~~D14~~ | **DELETED in v2.2 (SPEC v3.4).** Multi-mirror TOFU first-touch fake-root rejection. Not applicable under embedded-trust-base model. Future work: v2 multi-mirror TOFU reintroduction. | — | — | — | — | +| ~~D15~~ | **DELETED in v2.2 (SPEC v3.4).** TLS cert pinning against `MIRROR_CERT_PINS`. Constant deleted; cert pinning is v2 future work. | — | — | — | — | +| ~~D16~~ | **DELETED in v2.2 (SPEC v3.4).** Mirror-list tampering via `MIRROR_LIST_SHA256`. Constant deleted; mirror-list integrity is v2 future work. | — | — | — | — | +| **D17** | IPFS gateway list empty / all gateways down. | All IPFS gateways unreachable. | CAR fetch fails on all mirrors. On publish: CAR already pinned to local node; no failure. On recovery: persistent-retry loop (W7). | 24-hour persistent retry (§10.7). | +| **D18** | Monotonic clock enforcement: pointer versions use monotonic (not wall-clock) timestamps internally per SPEC §10.7 H7 requirement (v2 enhanced). | Fixture: `midLifecycle`. System time: jump backward (-1 hour). System time: jump forward (+2 hours). Publish at each step. | Pointer layer uses monotonic clock for version ordering (`getMonotonicTime()`, not `Date.now()`). Version advances regardless of wall-clock skew. Publish at v=K succeeds with monotonic timestamp K (ignoring wall-clock position). | Proofs from all three publishes verify (monotonic ordering preserved). No proof rejected due to wall-clock skew. `localVersion` advances monotonically: K → K+1 → K+2 (temporal order correct, wall-clock order irrelevant). | Monotonic clock prevents version inversion from skew attacks. Temporal causality preserved despite wall-clock manipulation. I-VM (version monotonicity) enforced. | + +### Category E — Discovery Edge Cases + +**Rationale.** Recovery is an exponential-search phase followed by a binary-search phase, with boundary conditions at every step. The latest version might be at the `DISCOVERY_INITIAL_VERSION`, way higher (exponential ceil), or much lower (1). Sparse regions may exist (versions with no pointer published). CID validation and CAR fetching may fail. E1–E13 (plus E5b in v1) enumerate these edges. + +| ID | Scenario | Precondition | Steps | Expected | Assertion | +|---|---|---|---|---|---| +| **E1** | No pointer ever published (wallet brand new). | Fixture: `freshWallet`, no prior publishes. | Recover from aggregator. Aggregator returns exclusion proofs at `v = 1` and all exponential probes. | Recovery acknowledges "no pointer" (I-DR: version 0). | `localVersion` remains uninitialized or set to 0; no CAR fetched. | +| **E2** | Pointer at exactly `DISCOVERY_INITIAL_VERSION (1024)`. | Device publishes once at `v = 1024`. | Recover on fresh device. Exponential search starts at 1024, hits success immediately. | Binary search is skipped (already found). | Single probe at 1024; success. | +| **E3** | Pointer far exceeds `DISCOVERY_INITIAL_VERSION`; exponential search must scale up. | Device publishes at `v = 500_000`. | Recover. Exponential search doubles from 1024 → 2048 → ... → 512K+ until ceiling `DISCOVERY_HARD_CEILING (4.2M)`. | Exponential phase finds an upper bound; binary search narrows. | Binary search converges to `v = 500_000`. | +| **E4** | Pointer at version 1 (boundary). | Device publishes at `v = 1`. | Recover. Exponential search checks 1024, 512, 256, ... , 1. | Binary search at lower boundary converges to 1. | `v = 1` found. | +| **E5** | Pointer at very high version near ceiling (e.g., 4M); exponential search must not exceed ceiling. | Device publishes at `v = 3_000_000`. | Recover. Exponential phase scales to ceiling `DISCOVERY_HARD_CEILING (4.2M)`. | Ceiling is enforced; no probe beyond 4.2M. | Exponential probes stop at 4.2M; binary search within bounds. | +| **E5b** | Sparse pointer history: versions 1, 5, 10 published; versions 2–4, 6–9, 11+ empty. | Fixture: multi-version publish with gaps. | Recover. Probes may land on empty versions during exponential phase; binary search skips sparse regions. | Correct version (latest non-empty) is found despite gaps. | Probe results: `EMPTY ∨ MISSING` on gaps; final version correct. | +| **E6** | CID too large (>CID_MAX_BYTES, 63 bytes): publish rejects at validation. | Fixture: generate CID of 70 bytes (e.g., CIDv1+sha512). | Publish rejects before submitting to aggregator. | Error: `AGGREGATOR_POINTER_CID_TOO_LARGE`. | No SMT entry created. Next publish with valid CID succeeds at bumped version. | +| **E7** | CID decode fails (payload is not a valid CID). | Fixture: XOR-decrypt payload; bytes are not a valid CID (e.g., random 32-byte garbage). | Recover at that version. Fetch CAR (aggregator claims CID is present); CAR does not exist (404 or corrupted at gateway). | Error: `AGGREGATOR_POINTER_CORRUPT` (CID decoding failed). | Persistent retry on CAR fetch; skip to next version if `DISCOVERY_CORRUPT_WALKBACK` exceeded. | +| **E8** | Corrupt streak: 100 consecutive versions are all unparseable CIDs (or fail CAR fetch). | Fixture: many corrupt entries in pointer history. | Recover. Walk back through versions; skip corrupt entries. At 65 consecutive corrupt (threshold `DISCOVERY_CORRUPT_WALKBACK`), stop and escalate. | Error: `AGGREGATOR_POINTER_CORRUPT_STREAK`. | Operator override via `acceptCorruptStreak()` allows proceeding. Otherwise halt. | +| **E9** | Empty version range (all probed versions have no pointer): exponential search scales to ceiling; binary search finds nothing. | Fixture: wallet with no publishes + aggregator state reset. | Recover. Exponential and binary search both return EMPTY at every probe. | Graceful no-op; recovery succeeds with `v = 0` (no pointer yet). | No error; `localVersion` initialized to 0 or left unset. | +| **E10** | Inclusion proof fails verification (bad merkle path, wrong root). | Fixture: mock aggregator returns invalid InclusionProof. | Recover; verify proof via `InclusionProof.verify(trustBase, requestId)`. | `verify()` returns `PATH_INVALID` or `NOT_AUTHENTICATED`. Recovery aborts. | Error: `AGGREGATOR_POINTER_UNTRUSTED_PROOF`. Escalate to user; manual recovery via alternate path. | +| **E11** | Exclusion proof fails verification. | Fixture: mock aggregator returns invalid ExclusionProof. | Recover; verify proof (ensures "no version at V+1"). Proof is bad. | `verify()` returns `PATH_INVALID`. Recovery aborts. | Error: `AGGREGATOR_POINTER_UNTRUSTED_PROOF`. | +| **E12** | Binary search lower bound at 1; upper bound at discovered exponential ceiling. Search terminates correctly. | Fixture: version 50 is latest. | Exponential search scales to 1024, detects 512 is also valid. Binary search: bounds [1, 1024], narrows to [1, 512], narrows to [50, 256], narrows to [50, 128], ..., converges to 50. | Binary search terminates at 50. | Correct version found. | +| **E13** | Discovery timeout (probes take too long; user/app timeout exceeded). | Fixture: mock aggregator slow on each probe (near PROBE_REQUEST_TIMEOUT_MS). | Recovery run 30+ probes (exponential + binary search combined). If total exceeds user-specified timeout, stop and return partial result or error. | Either completes successfully or returns graceful timeout error with last-known version. | App handles partial recovery (fall back to local history). | + +### Category F — Trust Base Discipline + +**Rationale.** The trust base (RootTrustBase) is the cryptographic root used to verify aggregator proofs. It must be loaded from a configured trusted source, identical across the pointer layer and L4, and rotated safely. F1–F9 ensure the trust base is never bypassed. + +| ID | Scenario | Fixture | Steps | Expected | Assertion | +|---|---|---|---|---|---| +| **F1** | **AMENDED v2.2:** Trust base loaded at init; used for first proof verification. `RootTrustBase` is the embedded bundle from `assets/trustbase/.ts` (SPEC v3.4 §8.4) — identical instance L4 uses. | Fixture: `freshWallet`. | Instantiate `OracleProvider` (or `PaymentsModule`); call `OracleProvider.getRootTrustBase()`. Verify first proof against it. | Proof verification succeeds (assuming canonical aggregator state). | `InclusionProof.verify(trustBase, requestId)` returns OK; no remote fetch, no cache logic. | +| **F2** | **AMENDED v2.2:** Trust base is shared instance with L4. | Fixture: L4 and pointer layer running in same process. | Both L4 and pointer layer call `OracleProvider.getRootTrustBase()`. | Both return the identical embedded instance (reference equality). | No divergence; shared embedded bundle (SPEC v3.4 §8.4.2 H6). | +| **F3** | **AMENDED v2.2:** Trust base rotation via SDK update. | Fixture: `midLifecycle`; aggregator begins returning epoch > bundled epoch. | (1) Old epoch active; proofs verify. (2) Aggregator advances its epoch while wallet still ships the older bundle. (3) Wallet detects epoch mismatch. | `AGGREGATOR_POINTER_TRUST_BASE_STALE` raised; user prompted to update SDK. Mid-session runtime rotation is v2 future work. | No silent acceptance of unverified rotation; no token loss. | +| **F4** | **AMENDED v2.2:** Absent embedded trust base. Defensive check — the SDK must refuse to initialize without a bundled `RootTrustBase` for the selected network. | Fixture: synthetic build missing `assets/trustbase/.ts` entry. | Instantiate `OracleProvider`. | Init throws `AGGREGATOR_POINTER_PROTOCOL_ERROR` (or equivalent) referencing the missing bundled trust base. No runtime remote-fetch fallback in v1. | No silent "unverified" mode; absent bundle is a build-time failure, caught at init. | +| **F5** | **AMENDED v2.2:** `OracleProvider.getRootTrustBase()` returns the same instance `PaymentsModule` uses. | Fixture: `pointerInitialized`. | From within a single process, obtain the trust base from (a) `OracleProvider.getRootTrustBase()` and (b) the instance that `PaymentsModule` uses internally. Assert reference equality. | Same `RootTrustBase` instance reference. | No duplicate bundled copies; H6 shared-base contract holds (SPEC v3.4 §8.4.2). | +| **F6** | **AMENDED v2.2:** Determinism — `OracleProvider.getRootTrustBase()` returns the same bytes across repeated calls within a session and across fresh processes on the same SDK build. | Fixture: fresh process × 2. | Serialize the trust base on each call; compare. | Byte-identical across calls. | No hidden mutation or per-call derivation in v1; trust base is a static embedded constant. | +| **F7** | Proof verification against wrong root (attacker-controlled aggregator response against the genuine embedded root). | Fixture: mock aggregator returns proofs against a fake root different from the bundled `RootTrustBase`. | Recover; fetch proofs. Verify proofs against the embedded root. | Proofs fail verification (merkle path does not match embedded root). Recovery aborts. | `InclusionProof.verify()` returns `PATH_INVALID` or `NOT_AUTHENTICATED`. No token loss (proofs blocked). | +| **F8** | **AMENDED v2.2:** SDK-level epoch divergence — two processes running **different SDK builds** (bundling different embedded epochs) must each detect the mismatch against aggregator state and raise `AGGREGATOR_POINTER_TRUST_BASE_STALE`. | Fixture: process A on SDK bundle epoch N, process B on epoch N-1. Aggregator runs at epoch N. | Both processes attempt recovery. | Process A: proofs verify. Process B: epoch mismatch detected → `TRUST_BASE_STALE` raised; user prompted to update SDK. | Divergence is a build-version concern in v1, surfaced via explicit error code; no silent drift (SPEC v3.4 §8.4). | +| **F9** | Trust base is always verified before use (no bypass paths). | Fixture: pointer layer with instrumented proof-verify function. | Run 100 recovery scenarios (category E). Count proof-verify calls. | At least 100 verify calls (≥1 per recovery). | Every proof is verified before trust. No code path accepts proofs without verification. | + +### Category G — `acceptCarLoss` Operator Override Discipline (H7) + +**Rationale.** CAR bundles can be permanently unavailable (gateways down, content lost). The pointer layer MUST NOT brick the wallet; instead it implements a persistent-retry mechanism (24-hour window) and offers an operator-callable `acceptCarLoss()` override. G1–G7 ensure the override is discipline-gated and doesn't lose token recovery. + +| ID | Scenario | Fixture | Steps | Expected | Assertion | +|---|---|---|---|---|---| +| **G1** | CAR unavailable; persistent-retry window not yet elapsed (< 24 hours). | Fixture: publish at `v = 1`; CAR pinned and discoverable. Then simulate 4-hour window with no gateway reachability. | Recover; CAR fetch fails on all gateways. Persistent retry scheduled; user notified. Time: 4 hours elapsed. | `acceptCarLoss()` call is REFUSED with `AGGREGATOR_POINTER_CARRETRY_WINDOW_ACTIVE`. User must wait or recover via alternate (legacy IPNS, trusted peer). | Timeout not elapsed; override rejected. | +| **G2** | Republish-before-advance ordering (H7 closure): CAR lost at `v = K` → persistent-retry on same `v` → republish CID at `v = K` (if CID changes) → only then advance to `v = K+1`. | Fixture: `midLifecycle` with pointer published at `v = K`. Gateway fails; CAR lost. Wallet enters persistent-retry. Meanwhile, user modifies wallet (new payment received), CID changes. | Step 1: Persistent-retry loop attempts CAR fetch every N seconds. Step 2: After budgeted retry window, persistent-retry still ongoing (not yet elapsed). Step 3: New token arrives; CID changes. Step 4: Wallet MUST first: (a) Republish at `v = K` with new CID, (b) THEN advance to `v = K+1`. Step 5: Verify: pointer history shows `[v=K (new CID), v=K+1 (next CID), ...]` with no gap. | Publish order verified: `v = K` (new CID) before `v = K+1`. Token inventory from persistent-retry CAR recoverable from `v = K` without advancing past it first. | H7 ordering enforced: republish same version with updated CID, confirm success, only then bump version. OTP reuse prevented; causality preserved. | +| **G3** | CAR loss on one version; other versions OK. Recovery skips lost version. | Fixture: publish at `v = 1..5`. Gateway only has `v = 1, 3, 5`; `v = 2, 4` lost. | Recover. Probes find up to `v = 5`. Fetch CARs for each version. `v = 2, 4` fail; skip. `v = 1, 3, 5` succeed. | Recovery loads from `v = 1, 3, 5` bundles; tokens merged via OrbitDB JOIN. | Tokens from `v = 1, 3, 5` recovered; no token loss (assuming v=2,4 contained no new tokens). | +| **G4** | Partial CAR loss: v = K is found but CARv = K-1 is lost mid-chain. Recovery must be able to bootstrap from partial history. | Fixture: `v = 1, 2, 3, ...` all published. Gateway has `v = 3, 4, 5` but not `v = 1, 2`. | Recover; find `v = 5` as latest. Attempt CAR fetch for `v = 5`: success. Then `v = 4`: success. Then `v = 3`: success. Then `v = 2`: 404 (lost). | Recovery succeeds with `v = 3, 4, 5` tokens. Optional: persist marker that `v = 2` is known-lost (to avoid re-querying). | `v = 3, 4, 5` tokens recovered; `v = 1, 2` are marked unrecoverable. | +| **G5** | `acceptCarLoss()` called without BLOCKED flag set (permission check). | Fixture: recovery idle, no BLOCKED state. | Call `acceptCarLoss()` directly. | Call rejected: `AGGREGATOR_POINTER_NOT_BLOCKED` (permission: only callable when recovery halted due to CAR loss). | Authorization enforced. | +| **G6** | Operator calls `acceptCarLoss()` during active persistent-retry sleep. | Fixture: CAR lost; persistent retry scheduled for 1 hour hence. | Call `acceptCarLoss()` before timeout. | Override honored; persistent-retry loop canceled. `acceptCarLoss()` returns immediately. | Operator gains immediate control; unblocks wallet. | +| **G7** | Multiple calls to `acceptCarLoss()` (idempotency). | Fixture: `blockedState` due to CAR loss. | Call `acceptCarLoss()`. State transitions: `BLOCKED_DUE_TO_CAR_LOSS → NOT_BLOCKED`. Call again. | Second call: no-op (state already not blocked). | Idempotent; no side effects. | + +### Category H — `clearPendingMarker` Operator Override Discipline (W6) + +**Rationale.** The pending-version marker is crash-safety critical but can become corrupt (W6). The operator-callable `clearPendingMarker()` is a recovery escape hatch, capability-gated to prevent accidental loss. H1–H4 plus H8-R, H14-R (regression tests, v2 new) ensure marker corruption is handled safely. (H3-R removed in v2.2 / SPEC v3.4 — multi-mirror TOFU is v2 future work.) + +| ID | Scenario | Fixture | Steps | Expected | Assertion | +|---|---|---|---|---|---| +| **H1** | Pending marker is corrupt; `clearPendingMarker()` clears it and sets BLOCKED. | Fixture: marker file has partial JSON. | Call `clearPendingMarker()`. | Marker file deleted. BLOCKED flag SET to `true`. Next publish REFUSED. | BLOCKED prevents silent recovery; forces manual aggregator check before proceeding. | +| **H2** | `clearPendingMarker()` called without MARKER_CORRUPT error (user panic call). | Fixture: `blockedState` with no marker corruption (e.g., aggregator unreachable). | Call `clearPendingMarker()`. | Marker deleted (no-op if absent). BLOCKED flag set. | User gains recovery escape hatch. | +| **H3** | **AMENDED in v2.2 (SPEC v3.4):** Fake-root rejection against the embedded `RootTrustBase`. Previously specified multi-mirror TOFU cross-check is v2 future work. | Fixture: fresh wallet; mock aggregator responds with proofs against a root different from the embedded `RootTrustBase`. | Recover; verify the returned proof against the bundled trust base. | Proof fails verification (merkle path does not match embedded root). Recovery aborts with `AGGREGATOR_POINTER_UNTRUSTED_PROOF`. | Attack surface previously handled by multi-mirror diversity is now contained by: (a) verification against the embedded trust base (this scenario), (b) epoch-mismatch detection (C6 amended), and (c) SDK-update-gated rotation (F3). Cross-mirror TOFU is v2 future work. | +| **H4** | Marker corruption detection at startup (NOT a user-callable scenario; automatic). | Fixture: marker file corrupted (truncated JSON). | Wallet init detects corruption; logs error; raises flag without user action. | MARKER_CORRUPT error surfaced; `clearPendingMarker()` capability hint provided to user. | User intervention required; escape hatch available. | +| ~~H3-R~~ | **DELETED in v2.2 (SPEC v3.4).** Cross-mirror TOFU downgrade attack regression (sub-cases A/B/C). Not applicable under embedded-trust-base model. Reintroduce when multi-mirror TOFU lands in v2. | — | — | — | — | +| **H8-R** | REJECTED (AUTHENTICATOR_VERIFICATION_FAILED) burns version via localVersion=v (H8 closure, v2 new). | Fixture: `midLifecycle` at `v = K`. Publish at `v = K+1` with `ctA_K` (ciphertext from HKDF subkey A). | Step 1: Submit at `v = K+1` with `ctA_K`. Aggregator returns `AUTHENTICATOR_VERIFICATION_FAILED` (simulated: signature invalid, or requestId mismatch on REJECTED row of §7.3). Step 2: Persist `localVersion = K+1` (OTP burned per SPEC §7.3 H8: REJECTED outcome). Step 3: Attempt immediate retry at `v = K+1` with different plaintext `pA_K'` → re-derive `ctA_K'`. | Step 1: Aggregator rejects. Step 3: Wallet MUST refuse retry at same v with different ciphertext (OTP reuse prevention). Wallet either (a) returns permanent error AUTHENTICATOR_VERIFICATION_FAILED, or (b) forces bump to `v = K+2` with fresh keys. | OTP reuse impossible: same `(v, side)` cannot be used with different plaintext. Version burn is irreversible and prevents silent retry-loop DoS. Invariant I-CS (crash safety) preserved. | +| **H14-R** | Pending_version marker idempotent-retry regression (H14 closure, v2 new). | Fixture: publish at `v = K+1` with `cidHash_A`. Crash mid-publish; restart. Marker: `(v = K+1, cidHash_A)`. Current CID: `cidHash_A` (same). | Restart; publish flow re-enters. Marker present, same cid → idempotent retry. Re-derive payload deterministically. Re-submit. Aggregator: returns `REQUEST_ID_EXISTS` (idempotent). Wallet: recognizes as success (SPEC §7.3 row 4). | No OTP reuse; publish completes. | Determinism enforced: same (v, cid) → same xorKey, padding, payload. No variant paths. | + +### Category I — `acceptCorruptStreak` Operator Override Discipline (W7 Floor) + +**Rationale.** Recovery may encounter pathologically long sequences of unparseable CIDs (e.g., prior client bugs or adversarial injection). The pointer layer halts after DISCOVERY_CORRUPT_WALKBACK (64) consecutive corrupt entries. The `acceptCorruptStreak()` override allows operator to proceed at their own risk. I1–I4 ensure the override is properly guarded. + +| ID | Scenario | Fixture | Steps | Expected | Assertion | +|---|---|---|---|---|---| +| **I1** | 50 consecutive corrupt entries; threshold not exceeded. | Fixture: pointer history with 50 unparseable CIDs. | Recover; walk back through corrupt entries. Count reaches 50. | Recovery continues (threshold is 64); next valid entry found or ceiling reached. | No override needed; recovery completes. | +| **I2** | 65 consecutive corrupt entries; threshold exceeded. | Fixture: pointer history with 65 unparseable CIDs. | Recover; walk back. At 64 corrupt, halt. | Error: `AGGREGATOR_POINTER_CORRUPT_STREAK` surfaced. Recovery blocked. | User must call `acceptCorruptStreak()` or investigate underlying issue. | +| **I3** | `acceptCorruptStreak()` permits proceeding past corrupt streak. | Fixture: blocked state due to corrupt streak. | Call `acceptCorruptStreak()`. | Override honored; recovery continues past corrupt region. Find latest valid entry or ceiling. | Operator acknowledges risk; recovery proceeds. | +| **I4** | `acceptCorruptStreak()` called without CORRUPT_STREAK state. | Fixture: recovery idle, no corruption. | Call `acceptCorruptStreak()`. | Call rejected: `AGGREGATOR_POINTER_NOT_BLOCKED` (permission). | Authorization enforced; override only available when needed. | + +### Category J — CAR Bundle Integrity + +**Rationale.** CAR bundles are content-addressed; CID must match when fetched. Truncation, corruption, or gateway bugs can produce mismatched bytes. J1–J8 test CAR validation and error handling. + +| ID | Scenario [parameterized by size] | Fixture | Steps | Expected | Assertion | +|---|---|---|---|---|---| +| **J1a** | Small CAR (1 MB) round-trip: fetch, hash, verify [size=1MB]. | Fixture: `pointerInitialized` with 1MB CAR. | Publish → CAR pinned. Recover on device B → fetch → hash → verify. | Fetch succeeds; hash matches CID; recovery succeeds. | `verifyCidMatchesBytes(cid, bytes)` returns true. | +| **J1b** | Medium CAR (10 MB) round-trip [size=10MB]. | Fixture: `midLifecycle` with multiple tokens (10MB CAR). | Publish → CAR pinned. Recover → fetch (may stream) → hash → verify. | Hash matches CID; no truncation. | All tokens recovered; inventory intact. | +| **J1c** | Large CAR (100 MB, at capacity) [size=100MB]. | Fixture: many tokens (100MB CAR at CID_MAX_BYTES envelope). | Publish → pin. Recover → fetch all 100MB (respects MAX_CAR_BYTES limit). | Fetch succeeds; hash matches; recovery complete. | Largest-supported CAR size validated. | +| **J2** | CAR truncated mid-fetch (gateway closes connection early). | Fixture: CAR available; gateway closes after 50% sent. | Recover; CAR fetch: connection closed, incomplete bytes received. Attempt hash-and-verify. | `verifyCidMatchesBytes()` returns false. Error: `AGGREGATOR_POINTER_CORRUPT_CAR`. | Persistent retry triggered (W7). | +| **J3** | CAR corrupted (first byte flipped; content-address check fails). | Fixture: CAR pinned; bitflip injected in first byte. | Recover; CAR fetched completely. Hash computed. | Hash does NOT match CID. Error: `AGGREGATOR_POINTER_CORRUPT_CAR`. | Persistent retry or operator override. | +| **J4** | CAR serialization round-trip (multiple devices, same tokens, same CID). | Fixture: Device A publishes tokens. Device B recovers and re-publishes (without modifying tokens). Device C recovers. | Device B's CAR MUST have identical CID to Device A's (deterministic serialization). | CID of A === CID of B. Device C recovers identical inventory. | Deterministic CAR serialization verified. | +| **J5** | CAR partial corruption (oplog inside CAR is corrupted; deserialization fails). | Fixture: CAR fetched; contains corrupted OrbitDB OpLog bytes. | Recover; CAR fetched and unpacked. Deserialize OpLog. Parse fails. | Error: `AGGREGATOR_POINTER_CORRUPT_CAR` or `OPLOG_PARSE_ERROR`. | Token recovery fails; persistent retry or manual recovery. | +| **J6** | CAR fetch from multiple gateways (gateway 1 corrupted; gateway 2 OK). | Fixture: CAR pinned to gateways G1 and G2. G1 has truncated version; G2 has full version. | Recover; CAR fetch from G1 fails (hash mismatch). Retry on G2; succeeds. | G2's version verifies; recovery continues. | Fallback to alternate gateway works; no permanent loss. | +| **J7** | CAR fetch size exceeds MAX_CAR_BYTES (100 MiB). | Fixture: bundle exceeds size limit (should not occur, but defense-in-depth). | Recover; CAR fetch headers indicate size > 100 MiB. | Download refused before transfer starts. Error: `AGGREGATOR_POINTER_CAR_TOO_LARGE`. | Size check prevents resource exhaustion. | +| **J8** | CAR serialization includes denylist entry; deserialization filters it. | Fixture: CAR contains a token in the operator denylist. | Recover; deserialization skips denylist entries. | Denylist token absent from recovered inventory. Remaining tokens recovered. | Denylist is enforced during deserialization; no loss of non-denylist tokens. | + +### Category K — Originated-Tag Semantic Validation (H6, W11) + +**Rationale.** OrbitDB replication can receive remote entries with `originated-tag = 'user'` (claiming to be locally-originated). The receiver must downgrade to `'replicated'` and re-validate semantics. K1–K10 ensure forged tags are caught and do not trigger false BLOCKED states. + +| ID | Scenario | Fixture | Steps | Expected | Assertion | +|---|---|---|---|---|---| +| **K1** | Local publish: originated-tag = 'user' (correct). | Fixture: device publishes at `v = 1`. | Semantic validator checks originated-tag. | Tag is 'user' on the sending device. | Local entries always tagged 'user' unless corruption. | +| **K2** | Remote replicated entry: originated-tag = 'user' sent from Device B. | Fixture: `twoDeviceSync`. Device A receives OpLog entry from Device B with `originated-tag = 'user'`. | Receiver-authority rule (§10.4): downgrade to 'replicated'. Re-validate semantics. | Semantic re-validation passes (entry was valid when originated). | Entry accepted with downgraded tag. No false BLOCKED. | +| **K3** | Remote entry with mismatched originated-tag (claims 'user' but content signature is missing / invalid). | Fixture: adversary crafts entry with 'user' tag and invalid signature. | Semantic validator re-checks signature on downgrade. | Signature verification fails. | Entry rejected. Merge conflict resolved via JOIN rule. No BLOCKED. | +| **K4** | Merge conflict with originated-tag: Device A and B both claim 'user' at same version. | Fixture: `twoDeviceSync`. Both A and B write to same slot. | Merge: version comparison (lamport, hash tie-break per JOIN rule 1). One device's entry is canonical. | Only one entry tagged 'user'; loser's entry is marked 'replicated'. | Single 'user' tag per version after merge. No BLOCKED. | +| **K5** | Downgrade rule is monotonic (never re-upgrade 'replicated' → 'user'). | Fixture: entry received as 'replicated', then merged again (perhaps device re-announces). | Merge: if entry is already 'replicated', stays 'replicated'. | No re-upgrade. | Tag is immutable (downgrade-only). | +| **K6** | Originated-tag DOES NOT trigger BLOCKED unless validation fails. | Fixture: `midLifecycle`. Entry with 'user' tag from Device B is replicated to Device A. | Semantic validation passes (signature OK, timestamp OK). Entry is accepted. | BLOCKED is NOT set (validation passed). | Pointer layer remains OPEN. | +| **K7** | Originated-tag on INVALID entry DOES trigger BLOCKED (H6 closure). | Fixture: entry claims `originated-tag = 'user'`, but semantic validation fails (e.g., token double-spent). | Semantic validator detects conflict. BLOCKED flag is SET (H1 closure). User must manually resolve. | BLOCKED prevents silent acceptance of invalid entry. | User is forced to investigate; no silent fork. | +| **K8** | Multi-device originated-tag quorum (3 devices agree on version; 1 disagrees). | Fixture: devices A, B, C publish to same v with same content; Device D has divergent content. | Merge (3-way quorum not in scope, but tags show origin). A, B, C: 'user'. D: 'replicated' (loses tie). | Majority's version is canonical. D's version downgraded. | No BLOCKED; merge proceeds. | +| **K9** | Originated-tag persists across CAR serialization (not dropped). | Fixture: `pointerInitialized`. OpLog entry has `originated-tag = 'user'`. Flush to CAR; deserialize. | Originated-tag is serialized in CAR; deserialized on recovery. | Tag is preserved through CAR round-trip. | Semantics on Device B match Device A. | +| **K10** | Originated-tag downgrade race during OrbitDB merge window (v2 new). | Fixture: Device A writes Profile v=5 with `originated-tag = 'user'`. Device B writes its own v=5 (different content) with `originated-tag = 'user'`. Both are offline. Bring online; replicate. During merge, both versions arrive at the merge operator simultaneously. | Receiver-authority rule: downgrade remote's tag to 'replicated'. Re-run semantic validation. Ensure the `user` tag is never falsely preserved on the remote-side version. | Both versions' `originated-tag` fields are examined. Exactly one (local-origin) is tagged `user`; remote is downgraded to `replicated`. | Token conservation: every token from both sides survives merge under JOIN rules (not lost). | + +### Category L — Identity / Key Handling + +**Rationale.** Keys are security-critical. L1–L7 test key derivation, storage, and usage. Denylist entries prevent initialization with weak keys. + +| ID | Scenario | Fixture | Steps | Expected | Assertion | +|---|---|---|---|---|---| +| **L1** | Canonical wallet 1 (all-zeros private key): denylist blocks initialization on testnet. | Fixture: attempt `Sphere.init()` with canonical test vector key. | Init rejects. | Error: `SPHEREKEYDENYLISTED` (or similar). | Canonical vectors are gated to `network: 'test-vectors'` or explicit override. | +| **L2** | Canonical wallet 2 (SHA-256 of string): denylist rejects on non-test network. | Fixture: canonical wallet 2 key. | Init on `network: 'testnet'` → rejected. Init on `network: 'test-vectors'` → allowed. | Denylist honored per network. | Test vectors are NOT usable on production. | +| **L3** | Key derivation determinism (HKDF same key → same derived keys). | Fixture: seed `signingSeed` deterministically. | Derive `signingService` via `SigningService.createFromSecret(signingSeed)` twice. | Both calls produce identical `signingPubKey`. | No randomness in key derivation; deterministic. | +| **L4** | Private key not exposed in API surface (no getter for `walletPrivateKey` in public types). | Fixture: Sphere instance. | Attempt to access `sphere.payments.walletPrivateKey` or equivalent. | Property not exported (type checker error or runtime undefined). | Private key is encapsulated. | +| **L5** | Key material zeroization (memory safety: derived subkeys are cleared after use if supported by runtime). | Fixture: publish flow with instrumented `memset` or equivalent. | Monitor memory for zeroization of `signingSeed`, `xorSeed`, `padSeed` after publish completes. | Keys are securely cleared (or JS engine garbage-collects them). | Memory forensics: no plaintext key material in heap after use. | +| **L6** | Operator denylist entry fires on deserialization (token in recovered CAR matches denylist). | Fixture: CAR contains a token in the operator denylist. | Recover; deserialize CAR. Token matches denylist. | Token is silently skipped (not added to inventory). Remaining tokens recovered. | No error; denylist is filtering (not blocking). | +| **L7** | Key rotation (if wallet switches to new mnemonic): old pointer chain is abandoned; new pointer chain starts at v=1. | Fixture: Device has mnemonic M1 (recovered some state). User imports new mnemonic M2. | Pointer layer re-derives with M2. New `pointerSecret`, `signingPubKey`, request IDs. | Old pointer entries (from M1) are NOT recovered. New pointer chain starts fresh at v=1. | Device A and Device B (both importing M2) converge to same state; M1's history is orphaned. | + +### Category M — Cross-Device Token Conservation (the heart of the invariant) + +**Rationale.** This is the **hardest** category. Two or more devices race, merge, crash, and recover. Tokens must never be lost, duplicated, or silently forked. M1–M12 (v1) plus M13–M15, M17 (v2 DAG-aware conservation) test the full state-machine and JOIN rules from PROFILE-ARCHITECTURE.md §10.4. (M7, M16 deleted in v2.1: finality-window concept not in SPEC; covered by H5 trust-base rotation.) + +| ID | Scenario | Fixture | Steps | Expected | Assertion | +|---|---|---|---|---|---| +| **M1** | Device A publishes at `v = 1` with token T1. Device B recovers. Both recheck. | Fixture: `twoDeviceSync` at `v = 0`. | A: publish(T1) → v=1. B: recover → finds v=1 → fetches CAR → loads T1. Both: `getTokens()`. | Both A and B have T1. | `A.tokens === B.tokens`. No loss. | +| **M2** | Device A at `v = 1` with T1. Device B recovers to `v = 1`. Device A consumes T1 (sends to third party). Device A publishes at `v = 2` (T1 spent, new T2 received). | Fixture: derived from M1 at `v = 1`. | A: send(T1) → receive(T2) → publish(v=2). B: (no action, still at v=1 state). Then B: recover again. | B's recovery finds v=2 CAR → loads final state (T1 gone, T2 present). | `B.tokens === [T2]`. No phantom T1. | +| **M3** | Device A and B both receive the same token T (from third party). Both attempt to consume it (double-spend). | Fixture: A and B both offline, receive T via Nostr DM. OrbitDB merge converges both to T in their OpLog. Both are online; both attempt to spend T. | A: spend(T, 50%) → receive from faucet. B: spend(T, 100%) → different recipient. A publishes at v=2 (A's state). B publishes at v=2 (B's state). | Race: aggregator includes A's v=2 (first to arrive). B's v=2 conflict → bumps to v=3. Recovery: v=2 (A's state, with A's spend), v=3 (B's state, with B's spend). JOIN rule at device merge: both spends are attempted; one conflicts. | Final inventory: either the conflict is caught upstream (L4 rejects invalid state transition) or token is marked QUARANTINED. No silent loss (H12 closure: audit trail). | +| **M4** | Device A publishes at v=1..v=10 (10 publishes, each with new token). Device B cold-boots and recovers. Device C also cold-boots and recovers. All three converge. | Fixture: Device A at `midLifecycle` state (v=5+); scale to v=10. | A: publish 10 times (each adds token). B: recover from scratch. C: recover from scratch. All run `getTokens()`. | B and C both recover all 10 tokens in causal order. OrbitDB merge on B and C produces identical inventory. | `A.tokens === B.tokens === C.tokens` (100 tokens total, all present). | +| **M5** | Crash during Device A's consume (spend + CAR flush). Restart Device A. Device B recovers state. | Fixture: A at v=3 with 5 tokens. Crash triggered during `send()` + `flushToIpfs()`. | A: crash (pending marker, partial CAR, maybe partial publish). Restart. B: recover (simultaneously or later). | A: restart recovers from marker (SPEC §7.1.6). Recomputes v=4. Publishes. B: recovers A's final state (v=4). | Both A and B have identical inventory. No double-spend of token A intended to send. | +| **M6** | Real oracle double-spend resolution (v2: replaced with M15). | [Scenario moved to M15] | — | — | — | +| **M8** | Device A publishes at v=1 (token T1). Device B concurrently publishes at v=1 (same T1, different consume intent). Devices merge via OrbitDB gossipsub. | Fixture: `twoDeviceSync` offline at v=0. A and B both add T1 to their local OpLog independently (before aggregator resolution). Both go online; publish races. | A: wins at v=1 (A's consume of T1). B: loses, publishes at v=2 (B's consume of T1). OrbitDB merge: both versions replicate to each other. JOIN rule: one is canonical (higher lamport / hash tie-break). Other is marked 'replicated'. | One consume is canonical; the other is marked replicated. Upon re-validation: likely one is invalid (attempt to re-spend the spent token). Semantic validator catches it (L4 oracle). | No fork; one branch is invalid and caught. Valid branch's tokens are preserved. | +| **M9** | Nametag recovery alongside pointer recovery: Device B imports mnemonic, recovers pointer at v=5, also recovers nametag from Nostr relay (independent of pointer). Tokens are under the recovered nametag's address. | Fixture: Device A with nametag '@alice', v=5 state. Device B: import mnemonic (no prior local state). | B: recover nametag from Nostr relay (event NIP-04 encrypted under pubkey). Recover pointer at v=5. Both reference the same identity (same HD address 0, same nametag). | B recovers both pointer state and nametag binding. Token inventory is intact. Nametag recovery is parallel (not serialized). | No race between nametag and pointer recovery; orthogonal. Tokens recovered correctly. | +| **M10** | Three-device eventual consistency: A, B, C all offline. A and B replicate to each other (v=5). C joins later. Eventual convergence. | Fixture: Device A at v=3, Device B at v=2, Device C at v=0, all offline with shared mnemonic. | (1) A and B replicate via OrbitDB gossipsub: both converge to merged state. (2) C joins, recovers pointer → finds latest. (3) All three run `getTokens()`. | After step (1): A and B have identical OpLog (merged). After step (2): C has recovered pointer → fetches same CAR as A/B. All three converge to same inventory. | No phantom tokens; no missing tokens. `A.tokens === B.tokens === C.tokens`. | +| **M11** | Selective offline recovery: Device A is offline. Device B recovers pointer from aggregator. Device A does NOT sync via network; only recovers from mnemonic offline (local OpLog seed via pointer). | Fixture: A offline (no network). B online. A has mnemonic. | A: perform offline recovery (compute `pointerSecret`, `signingPubKey`, probe local-cached aggregator state or manually provide latest-known version). A recovers from pointer without live network. | A's recovery succeeds if local cache is valid; otherwise A must go online to validate proofs. B's recovery is standard (online). Both should converge. | Offline-recovery tokens match online-recovery tokens (both are deterministic from mnemonic). | +| **M12** | Large token inventory (1000+ tokens across multiple CAR versions). Device A publishes in batches (v=1, v=5, v=10, v=20, v=50, v=100 with ~167 tokens each). Device B recovers once. | Fixture: scale the publish count to 1000+ tokens. | A: publish 6 times (batches). B: recover once → binary search → finds v=100 → fetches all CAR versions. | B recovers all 1000+ tokens. No truncation; no loss. | All tokens present; inventory matches A's. Scale test passes. | +| **M13** | JOIN rule 3 — longest-valid-chain with divergence (DAG-aware): two versions reference same token but branch on consume. JOIN must pick longest valid chain; loser's branch caught by semantic validator (v2 new). | Fixture: Construct two Profile versions V1 and V2 that both reference token T, but branch at consume step. | V1: [T, consume-T→send-to-R1, receive-U1] (3 ops, 2 valid + 1 pending). V2: [T, consume-T→send-to-R2, receive-U2] (3 ops, all 3 valid). Merge: both valid, V2 longer. | JOIN rule 3 (§10.4 PROFILE-ARCHITECTURE.md): both chains valid, one longer → keep longer (V2). V1's consume is replayed but re-spends T (already spent by V2). Semantic validator (L4 oracle) rejects V1's invalid spend as conflicting (§10.5.2, §10.7). | V2's tokens (send-to-R2, U2) preserved. V1's invalid-spend output is marked CONFLICTING. Final inventory: only V2's tokens recovered. Invariant I-TC: all valid tokens conserved; invalid ones flagged. | +| **M14** | JOIN rule 1–2 — manifest + element pool union (asymmetry preservation): one version has token that the other doesn't. Union must retain all uniquely-referenced tokens (v2 new). | Fixture: Device A has token T_a (received Nostr). Device B has token T_b (received Faucet). Both offline; then online; replicate via OrbitDB. | A's OpLog: [T_a, consume-T_a]. B's OpLog: [T_b, consume-T_b]. Merge: union of manifests includes both T_a and T_b. Element pool: union of all DAG nodes. | JOIN rules 1–2 (§10.4): (1) Manifests are UNIONED. (2) Element pools are UNIONED (content-hash dedup). Result: Final OpLog contains [T_a, T_b, consume-T_a, consume-T_b]. Both consumes valid per causality (consuming their respective inputs). | Both T_a and T_b conserved (manifest union). No loss. Final inventory: T_a-branch tokens + T_b-branch tokens. Invariant I-TC: union preserves all tokens from both branches. | +| **M15** | JOIN rule 3 tiebreak — double-spend detection + canonical selection: two versions both consume same input token. Merge must select one as canonical; loser's invalid spend quarantined (v2 new, replaces M6). | Fixture: Construct two versions that both consume same token T into different outputs. | V1: [T, spend-T-to-100-sats, receive-U1]. V2: [T, spend-T-to-150-sats, receive-U2]. Merge: both valid, same depth, lamport/hash tie-break picks V1 canonical, V2 replicated. | JOIN rule 3 tiebreak (§10.4): one canonical, other replicated. V2's spend is invalid (re-spends T already consumed by V1). Semantic validator (§10.5.2, §10.7 conflict) rejects V2's spend output. V2's U2 (received after the invalid spend) marked CONFLICTING or QUARANTINED. User notified. | V1's tokens (spend-to-100, U1) recovered. V2's U2 quarantined (pending manual resolution). No silent token loss; audit trail preserved. Invariant I-TC: canonical branch's tokens conserved; invalid-spend outputs flagged. | +| **M17** | Real oracle double-spend resolution via aggregator (v2 new): test against actual aggregator (not mocked). Submit two conflicting L4 state transitions. Aggregator consensus picks one. Wallet detects rejection and marks tokens from rejected branch QUARANTINED. | Fixture: Live testnet aggregator + integration test setup. | Device A: construct and submit state-transition V1 (token T spent to address R1). Device B: construct and submit conflicting V1 (same token T, different address R2). Time races. | Aggregator's BFT consensus includes first-to-arrive. Second is rejected (duplicate request-ID or conflicting L4 semantics). | Wallet detecting rejection: re-probes, sees only first is in SMT. Wallet marks second's new-token outputs as QUARANTINED. User is notified. | No silent loss. Both devices' tokens are accounted for; rejected-branch tokens are flagged for inspection. Final recovery preserves canonical tokens. | + +### Category N — CLI E2E Scenarios Against Real Infrastructure + +**Rationale.** Categories A–M are unit and integration tests. N1–N14 are end-to-end against real Unicity testnet infrastructure (aggregator, IPFS gateways, Nostr relay, faucet). They test the CLI binary and real-world latencies. + +[N1–N13 shell scripts preserved from v1; see §5 below for full bash code] + +| ID | Scenario | Command outline | Expected outcome | Success assertion | +|---|---|---|---|---| +| **N1** | Init new wallet with profile, publish, recover on second device. | `$CLI init --profile --nametag @alice-n1 --dataDir $DD_A` → receive faucet → `send @bob 1 UCT` → `profile flush` (explicit). Destroy. `$CLI init --mnemonic $MN --dataDir $DD_B --no-nostr` → wait for recovery. | Device B recovers all tokens from pointer. | `$CLI --dataDir $DD_B balance === amount_from_A` | +| **N2** | Multi-address: switch address, publish, recover on separate device. | `$CLI init --profile --dataDir $DD` → `address switch 1` → faucet → `send`. Destroy. Re-import on fresh device. | Recovery finds pointer at v=1; OpLog includes both address-0 and address-1 tokens. | Both addresses' tokens recovered. | +| **N3** | Concurrent publishes (two CLI processes, same wallet, race). | `(cd $DD && $CLI send @alice 1 UCT &) && (cd $DD && $CLI send @bob 1 UCT &) && wait` (mutex enforced at Profile level). | One succeeds; other may queue or conflict. Both eventually succeed (possibly at v+1). | No corruption; eventual consistency. | +| **N4** | Crash during send (SIGKILL, marker recovery). | `$CLI send @alice 1 UCT &` → PID=$! → sleep 0.1 → `kill -9 $PID`. Restart `$CLI send @bob 1 UCT` (should retry marker). | Crash-safety: marker-driven idempotent retry. Second send succeeds at v or v+1. | No OTP reuse; no token loss. | +| **N5** | IPFS gateway failover (two gateways, one down). | Publish to G1. Kill G1. Recover on device B using only G2. | CAR fetch from G2 succeeds. | Recovery finds and fetches CAR on alternate gateway. | +| **N6** | Aggregator briefly unreachable (simulated via iptables). | Publish at v=1. `iptables -A OUTPUT -d $AGGREGATOR_IP -j DROP`. Restart device. `iptables -D OUTPUT -d $AGGREGATOR_IP -j DROP`. `$CLI profile unblock` (or automatic recovery). | BLOCKED state set. After unblock, pointer recovery succeeds. | Pointer recovery resumes; tokens recovered. | +| **N7** | Network latency injection (slow aggregator; still completes). | Use `tc qdisc add` to delay aggregator RTT by 500ms. Publish. Latency added, but under timeout. | Publish succeeds (may take longer). | RTT budget validated (D11a). | +| **N7b** | BLOCKED persists across process restart (v2 new). | Device publishes at v=1. Aggregator mocked unreachable. BLOCKED flag set. Kill process. Restart device. Check status. | `$CLI profile status` shows BLOCKED=true. Publish refused until aggregator recovers. | BLOCKED state survives restart; user awareness enforced (H1 closure). | +| **N8** | Trust base rotation on recovery (new trust root published by aggregator). | Recover; trust base is current. Then aggregator's trust base rotates. Re-probe. | Proofs are re-verified against new root. | Seamless rotation; recovery continues. | +| **N9** | Selective offline recovery (pointer history cached locally, no aggregator). | Publish at v=1. Cache aggregator responses locally. Go offline. Recover (use cached latest version hint). | Offline recovery succeeds if cache is valid. | Pointer recovery skips aggregator query (uses cache). | +| **N10** | Long soak test: 24-hour continuous publish/receive. | 2 devices (A, B). A sends to B every 10 minutes for 24 hours. Periodic recovery on B. | A's balance decreases; B's increases. Final: A + B = initial. | Token conservation over extended period (I-TC hardening). | +| **N11** | High-volume send (100+ sends in rapid succession, batched CAR). | `for i in {1..100}; do $CLI send @alice 1 UCT --instant &; done; wait`. Multiple publishes batched into CAR. | All sends either succeed or are queued (not lost). | Token conservation (100 tokens sent, all either completed or in queue). | +| **N12** | Chaos: random SIGKILL during publish (20 iterations). | `for i in {1..20}; do $CLI send ... &; sleep 0.1; kill -9 $!; done`. Restart each time. | Marker-driven recovery; no OTP reuse; balance invariant. | Final balance after 20 crash-restart cycles === initial. | +| **N13** | Valid-version-continuity (corrupt version skipped on recovery). | Inject corrupt publish at v=1 (test flag `--test-inject-corrupt-publish`). Publish at v=2 (valid). Recover on fresh device. | Discovery skips corrupt v=1, finds v=2 as latest. | `pointer status` shows `localVersion: 2`. Corrupt version skipped. | +| **N14** | Legacy cold-start recovery without pointer layer enabled (v2 new). | Device created pre-pointer-layer (or pointer layer explicitly disabled in config). Cold-start recovery invoked. | Recovery falls back to legacy IPNS path (if available) or warns user. Wallet initializes without pointer. | Legacy recovery succeeds or gracefully degrades; no crash. Tokens recovered or user prompted for manual recovery. | + +### Category O — Chaos / Fuzz Tests + +**Rationale.** O1–O5 apply random fault injection and run recovery under stress. + +| ID | Scenario | Fixture | Fault injection | Expected | Assertion | +|---|---|---|---|---|---| +| **O1** | Fuzz aggregator response (random bytes, invalid JSON). | Fixture: `midLifecycle`. | Mock aggregator returns invalid JSON on 50% of requests. | Parser error; transient; retry. | No crash; error surface. | +| **O2** | Fuzz CID (random corruption, first byte flip). | Fixture: post-publish, mangle CID bytes. | XOR payload is corrupted on IPFS. | CAR fetch succeeds; hash fails verification. `AGGREGATOR_POINTER_CORRUPT_CAR`. | Persistent retry triggered. | +| **O3** | Latency fuzz (random jitter on aggregator RTT: 0–2 seconds). | Fixture: `midLifecycle`. | Aggregator mock adds random delay to each RPC. | Some requests timeout; some succeed. Retries with backoff. | No token loss; eventual success. | +| **O4** | Partial packet loss (random drop, 5–30%). | Fixture: integration test with network fault injection. | Mock transport drops packets randomly. | Timeouts increase; retries trigger. | Eventual success; no silent corruption. | +| **O5** | Clock jump (advance device clock +10 minutes mid-recovery). | Fixture: `blockedState`. | System time advanced; recovery re-probes. | Timestamp-dependent logic (e.g., cache expiry) may trigger. | Recovery continues; no crash. | + +### Category P — Conformance & Security Invariants (v2 new) + +**Rationale.** P1–P8 test that the implementation conforms to the spec at a structural level: proofs are verified, SDK calls use the correct signatures, domain separation is correct, etc. + +| ID | Scenario | Precondition | Test | Expected | Assertion | Maps to finding | +|---|---|---|---|---|---|---| +| **P1** | Proof-verify-always: every aggregator proof read is verified before trust. | Fixture: integration test with instrumented proof-verification function. | Run 100 recovery scenarios (from category E) + 100 publish scenarios.

No code path bypasses verification. | I-TV (trustless verification) | +| **P2** | Trust-base verification is always against TOFU-pinned root, not runtime-fetched. | Fixture: proof verification function instrumented to log trust-base source. | Run recovery 20 times. Log whether trust base was fetched or cached. | At least 10 recoveries use cached trust base (no fetch). Proofs all verify against that cached root. | Trust base reuse reduces fetch surface.

Staleness defense is not part of the v1 security model — trust base is embedded (SPEC §8.4 v3.4) and proofs are verified against the pinned `RootTrustBase` regardless of wall-clock age. Clock-skew concerns are addressed by D18. This scenario will reopen in v2 if staleness-rejection becomes necessary. | — | — | — | — | REMOVED | +| **P4** | SigningService constructor usage: only `createFromSecret` is used, never raw constructor (all modules). | Fixture: code inspection (AST grep). | Search pointer layer + PaymentsModule + AccountingModule + SwapModule + CommunicationsModule for `new SigningService(...)` calls. | Zero raw constructor calls across all modules. All calls use `SigningService.createFromSecret(...)`. | Constructor discipline enforced; no accidental raw instantiation. | H8 | +| **P5** | RequestId formula: calls conform to `RequestId.createFromImprint(publicKey, stateHash.imprint)` or `.create(publicKey, stateHash)` (all modules). | Fixture: code inspection (AST grep). | Search pointer layer + PaymentsModule + AccountingModule + SwapModule for custom RequestId derivations (e.g., manual hash(pubkey \|\| ...) patterns). | All calls are SDK-mediated. Zero custom-hash RequestId derivations outside SDK. | Formula integrity enforced across modules; no deviation. | W1 (SDK conformance) | +| **P6** | RequestId formula test vectors: known-answer tests for `requestId` derivation. | Fixture: SPEC §14.2 test vectors. | Derive `requestId_A(v=1)` and `requestId_B(v=1)` using canonical wallet 1. Compare against test-vectors.json. | Exact byte match on derived requestIds. | Formula is correct; test vectors lock down the implementation. | W1 | +| **P7** | SDK version pin: pointer layer code pins state-transition-sdk to a specific version range. | Fixture: `package.json` inspection. | Read `@unicitylabs/state-transition-sdk` peer-dep version.

Test Harness Specification & Fixtures + +### 3.1 Fixture definitions (consolidated for v2) + +Each scenario references a fixture by name. Common fixtures are pre-defined: + +| Fixture | Description | Setup | +|---|---|---| +| **`freshWallet`** | Brand new mnemonic, no prior state. Wallet created via `Sphere.init({ autoGenerate: true })` on a clean `dataDir`. | Storage provider configured for `network: 'testnet'`. No previous OpLog bundles. `localVersion` uninitialized. BLOCKED flag absent. No pending marker. | +| **`pointerInitialized`** | Wallet + pointer state at `v = 1` with one valid CID pinned to IPFS and included in aggregator SMT. | Derived from `freshWallet`; one publish completed and verified. `localVersion === 1`. Marker absent. OrbitDB seeded with one bundle. | +| **`midLifecycle`** | Wallet at `v = 5` with 3 tokens, 2 mirrors trusted for TOFU, no trust-base rotation pending. | Derived from `pointerInitialized`; 4 additional publishes completed (v=2–v=5). 3 distinct tokens spread across versions. Multi-mirror TOFU check has converged. No stale trust-base state. | +| **`twoDeviceSync`** | Same mnemonic on two devices (A, B), both at `v = 5`, fully converged via pointer recovery + OrbitDB merge. | Device A: `midLifecycle` state, then OrbitDB bundles pinned to shared IPFS. Device B: `freshWallet`, then cold-start recovery to `v = 5`, then device A's bundles fetched via gossipsub merge. Both show `localVersion === 5` and identical token inventory. | +| **`blockedState`** | Wallet with BLOCKED flag set (either via aggregator unreachability on init, or via REJECTED response on attempted publish). Publish is refused until BLOCKED is cleared. | Derived from `pointerInitialized` or `midLifecycle`; aggregator mocked to return transient error or REJECTED on next publish. BLOCKED flag persisted. User must manually call `sphere profile unblock` or wait for recovery. | + +### 3.2 Framework-level token conservation harness + +**New for v2.** Every test scenario's `afterEach` hook MUST call: + +```typescript +TokenConservationInvariant.assert( + stateBeforeScenario: TokenSnapshot, + stateAfterScenario: TokenSnapshot, + expectedDelta: { sent?: amount, received?: amount, expectedNet: amount } +) +``` + +Where `TokenSnapshot` is: +```typescript +interface TokenSnapshot { + tokens: Token[]; + totalCount: number; + totalAmount: bigint; + coinBreakdown: Map; +} +``` + +The helper MUST: +1. Assert `stateAfterScenario.totalCount === stateBeforeScenario.totalCount + expectedDelta.received - expectedDelta.sent`. +2. Assert every token ID from before-state is present in after-state (no token deletion). +3. Assert total amount delta matches expectation (no phantom creation or loss). +4. On failure, emit a clear "TOKEN CONSERVATION VIOLATED" error with diff details. + +This invariant is **framework-level**, meaning failures bubble up as test harness failures, not test-case failures. The rationale: token conservation is a contract the entire pointer layer makes, not a property of individual scenarios. + +--- + +## 4. Coverage Matrix (H/W Findings → Tests) + +**Objective:** Every critical finding (H1–H14) and warning finding (W1–W12) from SPEC §16 changelog must be covered by at least one PRIMARY test (scenario where the finding is the main test purpose) and at least one SECONDARY test (scenario that exercises the finding indirectly as part of broader test logic). + +| Finding | Title | Description | PRIMARY Test(s) | SECONDARY Test(s) | +|---|---|---|---|---| +| **H1** | Transient-vs-permanent error classification | Discovery must distinguish `SEMANTICALLY_INVALID` (skip corrupt, continue walking) from `TRANSIENT_UNAVAILABLE` (halt + `AGGREGATOR_POINTER_CAR_UNAVAILABLE`). | E7, E8 (corrupt CID handling + corrupt streak escalation) | D6 (partial CAR → persistent retry); D17 (all gateways down → persistent-retry loop) | +| **H2** | Monotonic probe predicate | Probe predicate is `aIncluded OR bIncluded` (monotonic). Phase 3 still enforces stricter both-sides check. | A2 (sequential publishes discover monotonically increasing version) | C2 (multi-device recovery order preserved) | +| **H3** | H3 — v2 future work (bundled trust base in v1 — see SPEC v3.4 §8.4) | Multi-mirror TOFU cross-check deferred to v2.

Overview + +The **UXF Profile** is a key-value table that represents the complete persistent state of a Sphere user wallet. It serves as the universal storage schema for everything a wallet needs to store — identity, token inventory, transaction history, conversations, nametags, operational state, and metadata. + +The Profile is designed with a clear persistence hierarchy: + +``` +┌─────────────────────────────────────────────────────┐ +│ OrbitDB Layer (Source of Truth — persistent, CRDT) │ +│ Profile stored as OrbitDB KeyValue database │ +│ Automatic conflict resolution via Merkle-CRDTs │ +│ Replicated across devices via libp2p/IPFS │ +├─────────────────────────────────────────────────────┤ +│ IPFS Layer (Content-Addressed Storage) │ +│ Token inventories stored as UXF CAR files │ +│ Multiple bundle CIDs — lazily consolidated │ +├─────────────────────────────────────────────────────┤ +│ Local Cache Layer (Transient — fast, untrusted) │ +│ Browser: IndexedDB / OPFS │ +│ Node.js: SQLite / LevelDB / JSON files │ +│ Mobile: SQLite / AsyncStorage │ +│ Serves as read cache + write-behind buffer │ +└─────────────────────────────────────────────────────┘ +``` + +**Core principles:** + +1. **OrbitDB is the source of truth** for all profile KV data. Its Merkle-CRDT OpLog ensures automatic conflict resolution when the same wallet is accessed from multiple devices concurrently. No manual merge logic needed — OrbitDB's `keyvalue` database type uses last-writer-wins per key, and the OpLog guarantees causal ordering. + +2. **IPFS is the content store** for bulk token data (UXF packages as CAR files). The Profile stores CID references to these packages, not the packages themselves. + +3. **Local storage is a transient cache** that may be lost at any time (browser cache cleared, app reinstalled, device lost). On startup, the local cache is validated against OrbitDB state and rehydrated if stale or missing. Critical writes are not considered durable until replicated to OrbitDB. + +--- + +## 2. Profile Schema + +The Profile is a flat key-value table where each key is a string and each value is an IPLD-compatible data structure (serializable via dag-cbor). The schema is divided into **global keys** (wallet-wide) and **per-address keys** (scoped to an HD derivation address). + +### 2.1 Global Keys + +These exist once per wallet, regardless of how many HD addresses are derived. + +| Key | Value Type | Persistence | Description | +|-----|-----------|-------------|-------------| +| `identity.mnemonic` | bytes | OrbitDB | BIP39 mnemonic (password-encrypted at application level) | +| `identity.masterKey` | bytes | OrbitDB | Master private key (password-encrypted at application level) | +| `identity.chainCode` | bytes | OrbitDB | BIP32 chain code | +| `identity.derivationPath` | string | IPFS | Full HD derivation path | +| `identity.basePath` | string | IPFS | Base derivation path | +| `identity.derivationMode` | string | IPFS | `bip32` / `wif_hmac` / `legacy_hmac` | +| `identity.walletSource` | string | IPFS | `mnemonic` / `file` / `unknown` | +| `identity.currentAddressIndex` | uint | IPFS | Currently active address index | +| `addresses.tracked` | `TrackedAddress[]` | IPFS | Registry of all derived HD addresses | +| `addresses.nametags` | `Map` | IPFS | Nametag cache per address | +| `tokens.bundle.{CID}` | `UxfBundleRef` | OrbitDB | **Per-bundle reference — one key per UXF bundle (see Section 2.3)** | +| `transport.lastWalletEventTs` | `Map` | OrbitDB | Last processed Nostr wallet event timestamp per pubkey | +| `transport.lastDmEventTs` | `Map` | OrbitDB | Last processed Nostr DM event timestamp per pubkey | +| `groupchat.relayUrl` | string | OrbitDB | Last used group chat relay URL | +| `profile.version` | uint | OrbitDB | Profile schema version (for migrations) | +| `profile.createdAt` | uint | OrbitDB | Profile creation timestamp (seconds) | +| `profile.updatedAt` | uint | OrbitDB | Last modification timestamp (seconds) | +| `profile.consolidationRetentionMs` | uint | OrbitDB | Safety period before removing superseded bundles (default: 7 days, min: 24h) | + +**Cache-only keys (NOT in OrbitDB — local storage only):** + +| Key | Value Type | Description | +|-----|-----------|-------------| +| `tokens.registryCache` | JSON | Token metadata registry (fetched from remote) | +| `tokens.registryCacheTs` | uint | Registry cache timestamp | +| `prices.cache` | JSON | Price data from CoinGecko | +| `prices.cacheTs` | uint | Price cache timestamp | + +These are regenerated from external APIs and are not replicated.

IPFS-side garbage collection is a separate future workstream. The `removeFromProfileAfter` field controls only when the reference key is deleted from the Profile — the CAR file remains pinned on IPFS indefinitely until explicit GC logic is implemented. + +#### Why Multiple Bundles? + +When two devices operate on the same wallet concurrently: +- **Device A** sends a token → creates a new UXF bundle (CID_A) with the updated inventory → `db.put('tokens.bundle.' + CID_A, ref)` +- **Device B** receives a token → creates a new UXF bundle (CID_B) → `db.put('tokens.bundle.' + CID_B, ref)` +- These are **different OrbitDB keys** — no LWW conflict occurs. Both entries appear after replication. +- The wallet now has **two active bundles** with overlapping content + +#### Reading with Multiple Bundles + +When loading the token inventory, the client reads ALL active bundles and presents a merged view: + +``` +1. List all keys with prefix 'tokens.bundle.' → { CID_1: ref1, CID_2: ref2 } +2. Filter to active: refs where status === 'active' → [CID_1, CID_2] +3. For each CID: UxfPackage.fromCar(fetch(CID)) +4. Merge all packages: result = UxfPackage.create() + result.merge(pkg1) // add all tokens from bundle 1 + result.merge(pkg2) // add all tokens from bundle 2 (dedup by content hash) +5. The merged result is the complete token inventory +``` + +Since UXF deduplication is content-addressed, overlapping tokens between bundles produce zero duplication in the merged in-memory view. The merge is cheap — it's just a Map union keyed by content hash. + +**CID availability:** If an active bundle's CID cannot be fetched from IPFS (gateway down, CID unpinned externally), the wallet logs a warning and operates with the remaining available bundles. The unavailable tokens are marked as 'unresolvable' in the UI. A periodic pinning verification step checks that all active CIDs are still accessible. + +#### Lazy Consolidation + +Over time, multiple small bundles accumulate. A background consolidation process merges them: + +``` +1. List all keys with prefix 'tokens.bundle.' → filter to active → [CID_1, CID_2, CID_3] +2. Merge all into one UxfPackage +3. Export merged package: UxfPackage.toCar() → pin to IPFS → CID_merged +4. Update OrbitDB: + - db.put('tokens.bundle.' + CID_merged, { cid: CID_merged, status: 'active', ... }) + - db.put('tokens.bundle.' + CID_1, { ...existing, status: 'superseded', supersededBy: CID_merged, removeFromProfileAfter: now + 7d }) + - db.put('tokens.bundle.' + CID_2, { ...existing, status: 'superseded', supersededBy: CID_merged, removeFromProfileAfter: now + 7d }) + - db.put('tokens.bundle.' + CID_3, { ...existing, status: 'superseded', supersededBy: CID_merged, removeFromProfileAfter: now + 7d }) +5. After the safety period (7 days): db.del('tokens.bundle.' + CID_1), etc. +``` + +The safety period ensures that any device still referencing the old CIDs has time to sync and learn about the consolidated bundle. During the transition, both old and new CIDs are valid — clients that haven't synced yet can still read the old bundles. + +**Crash recovery for consolidation:** +- Before pinning the consolidated CAR, write a `consolidation.pending` key to OrbitDB: + `db.put('consolidation.pending', { sourceCids: [...], startedAt: timestamp, device: deviceId })` +- After pinning: add the new bundle key, mark source bundles as superseded, delete `consolidation.pending` +- On startup: if `consolidation.pending` exists, check if the consolidated CID was pinned: + - If pinned: complete the remaining steps (mark sources superseded, clean up pending key) + - If not pinned: delete the pending key and restart consolidation + +**Concurrent consolidation guard:** Before starting consolidation, check for `consolidation.pending` key. If another device's consolidation is in progress (started < 5 minutes ago), skip. If the pending entry is older than 5 minutes, assume the other device crashed and proceed. + +**Performance limits:** Maximum recommended active bundles: 20. If consolidation consistently fails and bundle count exceeds 20, the wallet enters degraded mode: new writes are blocked until consolidation succeeds or manual intervention clears stale bundles. + +#### Consolidation Triggers + +- **Automatic:** when active bundle count (keys with prefix `tokens.bundle.` and status `active`) exceeds 3, consolidate in background +- **Manual:** `UxfPackage.consolidateBundles()` API for explicit trigger +- **On sync:** when the profile loads from OrbitDB and finds multiple active bundles from other devices + +#### Bundle Lifecycle + +``` +active → superseded (after consolidation) → removed from Profile (after safety period) +``` + +Note: "removed from Profile" means the `tokens.bundle.{CID}` key is deleted from OrbitDB. The CAR file remains on IPFS — no unpinning occurs. IPFS-side garbage collection is a separate future concern. + +**Specification note:** The `UxfBundleRef` type and multi-bundle protocol should be added to SPECIFICATION.md as an appendix or separate specification document in a future update. + +### 2.4 Operational State (TXF Compatibility) + +The existing `TxfStorageData` fields map to UXF Profile as follows: + +| TxfStorageData Field | Profile Key | Notes | +|---------------------|-------------|-------| +| `_meta.address` | Derived from `identity.currentAddressIndex` | Not stored separately | +| `_meta.ipnsName` | Derived from identity key | Not stored | +| `_meta.version` | `profile.version` | Migrated | +| `_meta.formatVersion` | `profile.version` | Unified | +| `_tombstones[]` | **DERIVED** — not migrated to OrbitDB, rebuilt from oracle spent-checks | Not migrated | +| `_outbox[]` | `{addr}.outbox` | Migrated | +| `_sent[]` | **DERIVED** — rebuilt from token ownership predicates | Not migrated; history derived from pool | +| `_invalid[]` | `{addr}.invalidTokens` | Migrated | +| `_history[]` | **DERIVED** — rebuilt from token ownership predicates | Not migrated; history derived from pool | +| `_mintOutbox[]` | `{addr}.mintOutbox` | Migrated | +| `_invalidatedNametags[]` | `{addr}.invalidatedNametags` | Migrated | +| `_` entries | UXF element pool | Replaced by UXF | +| `archived-` | UXF element pool (archived flag in manifest) | Replaced | +| `_forked__` | UXF element pool (forked tokens ingested as separate token entries with metadata) | Migrated | +| `_nametag` / `_nametags` | `addresses.nametags` + UXF nametag tokens | Split | + +--- + +## 3.

Two devices adding different bundles write to different keys — no LWW conflict possible. | Merged view at read time via `UxfPackage.merge()` | +| **Messages / history** | Each entry is a separate `db.put()` with unique key | Union — OrbitDB preserves all writes from all devices | +| **Dedup sets** | Each ID is a separate key entry | Union — set grows monotonically | +| **Pending transfers** | Per-transfer key entries | Both devices' pending entries visible; confirmed entries removed by either device | + +**Key insight:** By storing each bundle as a separate OrbitDB key (`tokens.bundle.{CID}`), we avoid all conflict scenarios. Two devices adding different bundles write to different keys — no LWW conflict is possible. Each device simply adds its own key and the merged view at read time handles the rest. + +--- + +## 4. Profile as OrbitDB Database + +The Profile is stored as an **OrbitDB `keyvalue` database** backed by IPFS. Each profile key maps to an OrbitDB entry. OrbitDB handles replication, conflict resolution, and persistence automatically. + +### 4.1 OrbitDB Database Identity + +The OrbitDB database address is derived deterministically from the wallet's private key: + +``` +OrbitDB identity = OrbitDBIdentity(secp256k1PrivateKey(walletPrivateKey)) +Database address = /orbitdb//sphere-profile- +``` + +Only the wallet holder can write to this database (OrbitDB access control via identity). Any peer can replicate, but all values are AES-256-GCM encrypted — only the wallet holder can decrypt (Section 9). + +### 4.2 Data Organization in OrbitDB + +OrbitDB's `keyvalue` type stores each key as a separate OpLog entry. The Profile keys from Section 2 map directly: + +``` +db.put('identity.mnemonic', encryptedBytes) +db.put('identity.masterKey', encryptedBytes) +db.put('addresses.tracked', [...]) +db.put('tokens.bundle.bafy...', { cid: 'bafy...', status: 'active', ... }) +// transactionHistory: DERIVED from token pool, not stored in OrbitDB +db.put('addr1.messages', {...}) +... +``` + +Large values (messages, history) are stored as IPLD-linked sub-structures, so the OpLog entries contain only CID references to the actual data blocks on IPFS. + +### 4.3 OrbitDB OpLog and CRDT Merge + +Each `db.put(key, value)` appends an entry to the Merkle-CRDT OpLog: + +``` +OpLog (append-only, content-addressed) +├── entry_1: { key: 'tokens.bundle.CID_1', value: {cid: CID_1, status: 'active', ...}, clock: 1, device: A } +├── entry_2: { key: 'addr1.messages', value: CID_msgs_v1, clock: 2, device: A } +├── entry_3: { key: 'tokens.bundle.CID_2', value: {cid: CID_2, status: 'active', ...}, clock: 1, device: B } ← concurrent! +``` + +When two devices add bundles concurrently, they write to **different keys** (`tokens.bundle.CID_1` vs `tokens.bundle.CID_2`). No LWW conflict occurs — both entries coexist after replication. LWW only applies when two devices write to the **same** key (e.g., marking a bundle as superseded), which is resolved by Lamport clock ordering. + +### 4.4 Replication + +OrbitDB replicates via libp2p: + +- **PubSub (real-time):** When peers are online simultaneously, OpLog entries propagate in sub-second via libp2p gossipsub topic `orbitdb/` +- **Nostr relay as persistence fallback:** OrbitDB OpLog entries can be serialized as Nostr events (kind: 30078, encrypted content) for persistence on the existing relay infrastructure. This is NOT a thin adapter — it requires: (1) serializing OrbitDB OpLog entries to Nostr event format, (2) handling OpLog ordering (Nostr does not guarantee causal order), (3) implementing a custom OrbitDB replication protocol over Nostr. This is a **Phase 2 feature**. Phase 1 relies on standard libp2p PubSub for real-time replication and IPFS block exchange for cold sync. +- **DHT (fallback):** Standard IPFS DHT-based peer discovery as a last-resort fallback + +### 4.5 OpLog Growth Management + +OrbitDB's OpLog is append-only and grows indefinitely. For long-lived wallets: + +- **Periodic snapshots:** Every N months (configurable), create a fresh OrbitDB database from the current state, replacing the old one.

Re-running is safe and idempotent: tombstone + (tokenId, stateHash) dedup gives the joint inventory. +> 4. Token statuses, the structural manifest, and the local derived cache (tombstones / sent / history) are recalculated automatically by the Profile load path. +> 5. Legacy data is preserved by default; `--delete-legacy` opts in to cleanup AFTER a successful zero-rejection import. +> +> See `cli migrate-to-profile`, `profile/import-from-legacy.ts`, and `docs/QUICKSTART-CLI.md`. + +#### Legacy 6-step flow (deprecated `ProfileMigration` class) + +When `Sphere.init({ profile: true })` was called on a wallet that has legacy-format data (existing IndexedDB/file storage + old-format IPFS inventory), the following migration ran silently. Retained for backwards compatibility but no longer the recommended path: + +``` +1. SYNC OLD IPFS DATA FIRST + - For wallets that never used IPFS sync (no `sphere_ipfs_seq_*` keys), skip step 1 entirely. + - Resolve existing IPNS name → get latest old-format CID + - If IPNS resolution fails (expired name, network issues), skip step 1 and proceed + with local-only data. Log a warning: 'IPNS resolution failed — migrating from + local data only. Remote IPFS data may not be included.' The local data is likely + more recent than the last IPFS sync. + - Fetch old TXF data from IPFS + - Merge with local legacy storage (ensures we have the most recent state) + - This step MUST complete before transformation begins + +2. TRANSFORM LOCAL DATA + a. Read all StorageProvider keys → map to Profile key names (Section 5.2) + b. Read all TokenStorageProvider tokens (TXF format) + → Convert each to ITokenJson via adapter + → Ingest all into a single UXF bundle via UxfPackage.ingestAll() + c. Collect operational state: migrate _outbox, _mintOutbox, _invalidatedNametags to Profile per-address keys. Skip _tombstones, _sent, _history (these are DERIVED from the token pool after migration) + d. Persist the complete new Profile to local storage (new format) + +3. PERSIST TO ORBITDB + - Open/create OrbitDB database with wallet identity + - Write all Profile keys via db.put() + - Pin UXF CAR file to IPFS → record CID via db.put('tokens.bundle.' + cid, ref) + - Wait for OrbitDB local persistence (OpLog committed to IPFS blockstore) + +4. SANITY CHECK (mandatory — blocks until complete) + a. Read back all Profile keys from OrbitDB → compare with transformed data + b. Fetch UXF CAR from IPFS by CID → UxfPackage.fromCar() + c. For each migrated token: + - Verify tokenId exists in the UXF bundle + - Verify transaction count matches the original TXF token + - Verify the current state hash matches (fast check via SHA-256 of predicate + data) + d. For operational state: verify history entry count, conversation count, + and pending transfer IDs match + e. If ANY check fails: abort migration, keep legacy data, log error, continue + with legacy storage (no data loss) + +5. CLEANUP (only after step 4 passes completely) + a. Remove all legacy-formatted user data from local storage + (old IndexedDB entries, old file-based storage). + Note: the `SphereVestingCacheV5` IndexedDB database is NOT deleted during + cleanup — it is a standalone cache unrelated to the Profile migration. + It will be regenerated naturally by the VestingClassifier. + b. Unpin the last known CID from `sphere_ipfs_cid_{ipnsName}` (the only tracked + CID). Previous CIDs are not tracked and will be garbage collected by the IPFS + pinning service's retention policy. + c. The old IPNS name is no longer published to + +6. DONE — Profile is the sole storage layer from this point forward +``` + +**Recovery from interrupted migration:** Track migration state via a local-only key `migration.phase` (values: 'syncing', 'transforming', 'persisting', 'verifying', 'cleaning', 'complete'). On restart, resume from the last completed phase. If `migration.phase = 'verifying'` and OrbitDB profile exists, re-run steps 4 and 5 only. + +**Idempotency:** If migration is interrupted (app crash, network failure), it resumes from the last completed phase on next launch. The presence of an OrbitDB profile (step 4 passed previously) skips re-migration. + +--- + +## 8. Compatibility Layer + +### 8.1 Backward Compatibility + +The Profile system must be backward-compatible with existing sphere-sdk consumers: + +1. **`StorageProvider` interface unchanged** — `ProfileStorageProvider` implements the same `get/set/remove/has/keys/clear` interface. Existing code using `storage.get('mnemonic')` continues to work. + +2. **`TokenStorageProvider` interface unchanged** — `ProfileTokenStorageProvider` implements `save/load/sync` with `TxfStorageDataBase` type parameter. `PaymentsModule` sees no difference. + +3. **Migration path:** On first load with ProfileStorageProvider, detect existing data in legacy storage (IndexedDB `sphere-storage`, file-based storage) and migrate to Profile format. Legacy storage is preserved as fallback. + +### 8.2 Factory Functions + +``` +// Browser +createBrowserProviders({ network, profile: true }) + → returns ProfileStorageProvider (backed by IndexedDB cache + IPFS) + +// Node.js +createNodeProviders({ network, dataDir, profile: true }) + → returns ProfileStorageProvider (backed by SQLite cache + IPFS) + +// Legacy (no IPFS, local only) +createBrowserProviders({ network }) + → returns IndexedDBStorageProvider (existing behavior, no change) +``` + +The `profile: true` option enables the OrbitDB/IPFS persistence model. Without it, the existing local-only behavior is preserved. + +**Note on Sphere app:** The Sphere web app currently uses `WalletRepository` with raw `localStorage` — a separate, unsynchronized storage layer. Migrating the app to use `ProfileStorageProvider` is a separate follow-up task (app-level change, not SDK change). The SDK provides the `ProfileStorageProvider`; the app migration is documented but not blocked on. + +--- + +## 9. Security Considerations + +### 9.1 Storage Model: Unencrypted Elements, Encrypted Manifests + +UXF element blocks on IPFS are stored **unencrypted** (plaintext). This is a deliberate design choice that enables **cross-user deduplication** — the core value proposition of UXF. + +``` +IPFS (public, content-addressed, cross-user dedup): + element[hash_A] — unicity certificate (shared by N users, stored ONCE) + element[hash_B] — authenticator + element[hash_C] — SMT path + element[hash_D] — nametag token sub-DAG + ... + +OrbitDB (private, per-user, encrypted): + tokens.bundle.{CID} — encrypted bundle reference (CID, status, device) + (transactionHistory is DERIVED from token pool, not stored) + {addr}.messages — encrypted (DM content) + identity.mnemonic — password-encrypted (private keys) + ... +``` + +**What is encrypted (in OrbitDB):** All profile KV values — identity, bundle references (which CIDs belong to this user), messages, operational state. These reveal **which** bundles a user owns, **who** they transacted with, and **what** messages they exchanged. Note: the bundle manifests inside the CAR files on IPFS are unencrypted (they list tokenId→hash mappings but without user context this reveals nothing about ownership). Encrypted with `profileEncryptionKey = HKDF(masterKey, "uxf-profile-encryption", 32)` using AES-256-GCM with random IV. + +**What is NOT encrypted (on IPFS):** Individual UXF element blocks — token genesis data, state transitions, inclusion proofs, unicity certificates, predicates, authenticators, SMT paths. These are **cryptographic proof materials**, not secrets. + +### 9.2 Why Token Elements Are Not Secrets (Privacy Analysis) + +A common security concern is: "if token data is public on IPFS, can someone steal funds?" The answer is **no**, and here is why: + +**Token elements are cryptographic proofs, not authorization credentials.** To perform a state transition (transfer a token), an attacker needs the **private key** corresponding to the token's current predicate. The token elements on IPFS contain: + +| Element | Contains | Can an observer steal funds? | Can an observer learn anything? | +|---------|----------|-------|------| +| **UnicityCertificate** | BFT validator signatures for an aggregator round | No — proves round commitment, not ownership | Which aggregator round a transition was committed in | +| **Authenticator** | Public key + signature + state hash | No — signature proves a past transition, not future authorization | The public key that authorized a past transition | +| **Predicate** | Public key, signing algorithm, nonce | No — knowing the pubkey doesn't reveal the private key | The current owner's public key (already public in Nostr binding events) | +| **SMT Path** | Merkle tree path segments | No — proves inclusion in the aggregator's tree | Position in the Sparse Merkle Tree | +| **Genesis Data** | Token ID, type, coin data, recipient address | No — address is already public | Token denomination and recipient (already visible to aggregator) | +| **Token State** | Current predicate + data | No — same as Predicate above | Current ownership state | + +**The critical insight:** Unicity tokens derive their security from **private key custody**, not from data secrecy. The entire state transition chain is designed to be **publicly verifiable** — that's the point of inclusion proofs and unicity certificates. Hiding token elements behind encryption would be like encrypting a blockchain — it defeats the purpose of the transparency/verifiability model. + +**What IS private and must be encrypted:** +- **Manifests** — reveal which tokens a user owns (balance disclosure) +- **Transaction history** — reveals counterparties and amounts +- **DM messages** — private communications +- **Identity keys** — mnemonic and master key (fund access) +- **Operational state** — pending transfers, outbox (reveals intent) + +These are all stored in OrbitDB and encrypted with the profile key. + +### 9.3 Cross-User Deduplication (Why This Matters) + +By storing UXF elements unencrypted, we achieve **cross-user deduplication at the IPFS level**: + +``` +User A has token T (genesis + 3 transactions + proofs) +User B receives token T from A (same genesis + 3 transactions + 1 new transaction) + +With encryption (broken model): + User A: encrypt(CAR_A, key_A) → CID_X (encrypted blob, 15 KB) + User B: encrypt(CAR_B, key_B) → CID_Y (different encrypted blob, 20 KB) + IPFS stores: 35 KB (zero dedup — different keys produce different CIDs) + +Without encryption (correct model): + User A: UXF elements → individual IPLD blocks → CIDs based on content + User B: UXF elements → same blocks for shared history + 1 new block + IPFS stores: 20 KB (15 KB shared + 5 KB new — 43% saved) + +At scale (1000 users, 100 tokens each, tokens passing through ~5 owners on average): + With encryption: ~1000 × 100 × 15 KB = 1.5 GB (no dedup) + Without encryption: ~200 × 100 × 15 KB = 300 MB (80% dedup from shared elements) +``` + +The unicity certificates alone (shared by all tokens in the same aggregator round) represent 25-40% of token data. With 1000 users, the same certificate is stored once instead of thousands of times. + +### 9.4 Identity and Key Protection + +The `identity.mnemonic` and `identity.masterKey` fields receive **two layers of protection**: + +1. **Application-level password encryption** — the user's password encrypts the mnemonic via AES (consistent with existing `Sphere.init({ password })` behavior). Without the password, the mnemonic cannot be recovered even by someone with the profile encryption key. + +2. **Profile-level encryption** — the password-encrypted bytes are further encrypted with `profileEncryptionKey` before storing in OrbitDB. This prevents OrbitDB replication from exposing even the password-encrypted form to peers. + +### 9.5 OrbitDB Access Control + +OrbitDB databases are **writable only by the wallet identity** (secp256k1 key pair). The database address is derived from the wallet's public key. Other peers: +- **Cannot write** — OrbitDB `OrbitDBAccessController` restricts writes to the owner identity +- **Can replicate** — OrbitDB's libp2p PubSub allows peers to replicate the OpLog +- **Cannot decrypt** — all values are AES-256-GCM encrypted; the `profileEncryptionKey` is derived from the mnemonic which only the wallet holder possesses + +Even if a peer replicates the OrbitDB database, they see only encrypted blobs for all profile values. The only unencrypted data is on IPFS (UXF element blocks), which as analyzed in Section 9.2, contains only publicly-verifiable cryptographic proof materials. + +### 9.6 DM Message Privacy + +DM message content is encrypted with `profileEncryptionKey` before storing in OrbitDB. The NIP-17 gift-wrap privacy model is preserved: +- **Nostr relay** sees NIP-17 gift-wrapped (encrypted) events +- **OrbitDB/IPFS** sees AES-encrypted values +- **Only the wallet holder** can decrypt both layers + +### 9.7 Threat Model Summary + +| Threat | Mitigation | Residual Risk | +|--------|-----------|---------------| +| Attacker reads UXF elements on IPFS | Elements are cryptographic proofs, not secrets. Cannot steal funds without private key. | Attacker learns token structure (denomination, proof chain) — same as inspecting a public blockchain. | +| Attacker reads OrbitDB values | AES-256-GCM encryption. Key derived from mnemonic via HKDF. | None — ciphertext without key is computationally infeasible to break. | +| Attacker correlates CIDs to users | Manifests are encrypted in OrbitDB. CIDs of individual elements don't reveal ownership. | Attacker who monitors IPFS pin timing may correlate activity patterns (same as any network observer). | +| Attacker forges OrbitDB entries | OrbitDB access controller restricts writes to the wallet identity. | A compromised Helia node could present stale data (denial of service, not data theft). | +| Attacker compromises IPFS node | Token elements are public proof materials (no loss). Profile values are encrypted (no disclosure). | Storage denial — attacker could unpin data. Mitigated by multi-node pinning. | +| Attacker obtains mnemonic | Game over — full access to wallet, tokens, and profile. | Same as any wallet — mnemonic custody is the security boundary. | + +--- + +## 10. Token Versioning, Manifest Consolidation, and Oracle Validation + +### 10.1 Token DAG Versioning + +A token's DAG changes with every state transition. When a new transaction is appended, the TokenRoot element gets new children (the new transaction) and therefore a new content hash. The same `tokenId` can reference **multiple DAGs** representing the token at different points in its history: + +``` +tokenId: aaa111... + ├── DAG v1 (hash_R1): genesis only ← initial mint + ├── DAG v2 (hash_R2): genesis + 1 transfer ← after first transfer + └── DAG v3 (hash_R3): genesis + 2 transfers ← after second transfer +``` + +All three DAGs share most elements (genesis, first proof, certificate) — only the new transaction elements and the updated TokenRoot differ. The element pool deduplicates the shared parts. + +### 10.2 Two Kinds of Manifest + +The term "manifest" is used in two distinct contexts that must not be confused: + +#### 10.2.1 Bundle Manifest (package-level, STORED) + +The **bundle manifest** is a structural artifact of the UXF/CAR package format. It lists the DAG nodes contained in a specific bundle and how they link together. This is defined in SPECIFICATION.md Section 5.4 and is ALWAYS stored inside the CAR file as part of the package envelope. + +``` +Bundle Manifest (inside CAR file): + Envelope → manifest block → { tokenId_aaa: hash_R3, tokenId_bbb: hash_R1 } +``` + +Every standalone UXF bundle carries its bundle manifest. This makes the package **self-describing** — you can inspect a CAR file and know which tokens it contains without scanning every block. This is the SPECIFICATION's manifest, and the ARCHITECTURE's `UxfManifest` type (`Map`). + +#### 10.2.2 Token Manifest (wallet-level, DERIVED) + +The **token manifest** is a Unicity-level artifact that maps tokens to their latest valid DAG versions WITH status information. It is **never stored** — it is computed client-side after loading and joining one or more bundles. It incorporates oracle validation results, chain integrity checks, conflict detection, and ownership predicates. + +```typescript +interface TokenManifestEntry { + rootHash: ContentHash; // root of the primary (valid) DAG + status: 'valid' | 'invalid' | 'conflicting' | 'pending'; + conflictingHeads?: ContentHash[]; // alternative DAGs for investigation + invalidReason?: string; +} + +// Token manifest: derived, never stored +Map +``` + +The token manifest is **derived** by: +1. Reading bundle manifests from all active UXF bundles +2. JOINing them (union, longest valid chain per tokenId, proof enrichment) +3. Running the status derivation algorithm (Section 10.6) with oracle checks +4. Cached in local storage for fast reads, rebuilt on demand + +| | Bundle Manifest | Token Manifest | +|---|---|---| +| **Level** | Package/CAR structure | Wallet/Unicity semantics | +| **Stored?** | Yes (in CAR envelope) | No (derived client-side) | +| **Contents** | tokenId → rootHash (simple) | tokenId → { rootHash, status, conflicts } | +| **When created** | On `toCar()` serialization | On load/JOIN, after oracle validation | +| **Defined in** | SPECIFICATION.md Section 5.4 | PROFILE-ARCHITECTURE.md Section 10.11 | + +**Key distinction:** "latest known" in a bundle manifest is NOT necessarily "latest globally." Once a token has been transferred to another user, the original holder stops receiving updates. The token manifest's `status` field (via oracle checks) reveals whether the bundle manifest's version is still current or stale. + +### 10.3 UXF Minimalism Principle + +**The UXF bundle must be minimalistic** — it stores only the absolute minimum information needed for full profile reconstruction.

Required SDK API Additions + +The following API gaps must be addressed for proper token-type-based access to the inventory: + +### 11.1 PaymentsModule: Nametag Token Access (MISSING) + +The PaymentsModule has no public method for listing or extracting nametag tokens. Nametag tokens are regular tokens in the inventory with `tokenType = f8aa13834268d29355ff12183066f0cb902003629bbc5eb9ef0efbe397867509`. Currently they are accessed ad-hoc via internal `findNametagToken()` callbacks and `_nametag`/`_nametags` TXF fields. + +**Required additions:** +- `payments.getNametagTokens(): Token[]` — returns all nametag tokens for the current address, filtered by tokenType from the inventory +- `payments.getNametagToken(name: string): Token | undefined` — returns the specific nametag token for a given name + +These should use `UxfPackage.tokensByTokenType(NAMETAG_TOKEN_TYPE_HEX)` under the hood when Profile mode is active. + +### 11.2 AccountingModule: Invoice Token Access (EXISTS) + +The AccountingModule already provides comprehensive invoice access: +- `accounting.getInvoices(options?)` → `InvoiceRef[]` (listing) +- `accounting.getInvoice(invoiceId)` → `InvoiceRef | null` (single lookup) +- `accounting.getInvoiceStatus(invoiceId)` → `InvoiceStatus` with parsed `InvoiceTerms` +- `accounting.importInvoice(token)` → parses `InvoiceTerms` from `genesis.data.tokenData` +- `accounting.createInvoice(...)` → mints invoice token + +No changes needed — the accounting module correctly treats invoices as tokens and extracts structured data from `tokenData`. + +### 11.3 UxfPackage: Token Type Index (EXISTS) + +`UxfPackage.tokensByTokenType(tokenTypeHex)` already provides the underlying index lookup. Both PaymentsModule and AccountingModule should use this when operating in Profile/UXF mode, instead of scanning TXF fields directly. + +### 11.4 Token Type Constants (MISSING) + +Define well-known token type constants in the SDK: +```typescript +export const TOKEN_TYPES = { + NAMETAG: 'f8aa13834268d29355ff12183066f0cb902003629bbc5eb9ef0efbe397867509', + INVOICE: '', // TBD — needs verification from AccountingModule +} as const; +``` + +This avoids hardcoding hex strings across the codebase. diff --git a/docs/uxf/PROFILE-CID-REFERENCES.md b/docs/uxf/PROFILE-CID-REFERENCES.md new file mode 100644 index 00000000..f7fd9b0c --- /dev/null +++ b/docs/uxf/PROFILE-CID-REFERENCES.md @@ -0,0 +1,362 @@ +# Profile OpLog CID References — Design + +**Status:** Draft 1 — foundation for the fat-data migration (PaymentsModule, CommunicationsModule, GroupChatModule, AccountingModule) +**Precedes:** per-module refactor commits +**Cross-refs:** +- `PROFILE-OPLOG-SCHEMA.md` — envelope format (§5 write path already accommodates CID-ref payloads) +- `PROFILE-ARCHITECTURE.md` §4.5 — OpLog growth management +- Audit findings (commit message of 40662fe and its successor) + +--- + +## §1 Motivation + +The fat-data audit identified that several module write sites store unbounded user data (pending V5 tokens with full SDK data, V5 outbox with full `TransferResult`, DM messages, group chat state, invoice ledgers) directly in the OpLog as JSON blobs.

Each entry is ~80 bytes. 1000 entries = 80 KB — still under the 1 KiB inline rule's 100 KiB upper bound but worth monitoring. Phase 2 will introduce archival/sharding (older entries migrate to an `archive.` key with its own CID). + +### Pattern C — per-item OpLog key + +Not part of this design. Discussed for completeness: each item becomes its own OpLog entry (e.g. `messages.`). This was considered and rejected because: +- OpLog entry count growth is costlier than byte-count growth (each entry has merkle-CRDT overhead). +- "List all messages" requires iterating all keys matching a prefix, which is O(n) scan in OrbitDB. +- CRDT merge doesn't benefit per-item — messages aren't concurrent-edited. + +Pattern B keeps OpLog key count low while giving per-item granularity through the index. + +--- + +## §5 Encryption flow + +Both patterns preserve the existing encryption boundary. ProfileStorageProvider's `encryptProfileValue` / `decryptProfileValue` (AES-256-GCM with wallet-derived key) is used for the IPFS content as well. + +``` +Pattern A (whole-list): + plaintext list + → JSON.stringify + → encrypt(jsonBytes) via encryptProfileValue + → pinToIpfs(encryptedBytes) + → CID + → build CidRef { cid, size = encryptedBytes.length, ts, v:1 } + → ProfileStorageProvider.set(key, JSON.stringify(ref)) // ref ~100B, ProfileStorageProvider encrypts again at OpLog layer + +Pattern B (per-item): + For each new item: + → JSON.stringify(item) + → encrypt + → pinToIpfs + → CID entry for index + + Index write: + → update index.items array + → JSON.stringify(index) + → encrypt + → pinToIpfs + → CidRef → ProfileStorageProvider.set(...) +``` + +**Double-encryption cost:** negligible. The outer layer (ProfileStorageProvider encrypting the ref JSON) operates on a ~100-byte blob. The inner layer (CidRefStore encrypting the content) is what was always happening — we've just moved WHERE the ciphertext is stored. + +**Privacy note:** the CID itself is public (pinned content is visible at the IPFS layer). An observer correlating OpLog entries to IPFS pins learns that a specific wallet pinned specific CIDs. They do NOT learn the content (AES-256-GCM). Current threat model already accepts CID-level observability for UXF bundles; extending that to the OpLog-ref pattern adds nothing new. + +--- + +## §6 Migration strategy — dual-read, single-write + +Existing wallets have JSON blobs inline in OpLog. After this refactor ships, new writes always go through CID-ref. Reads detect which format is present: + +```typescript +async loadPendingV5Tokens(): Promise { + const data = await storage.get(PENDING_V5_TOKENS_KEY); + if (!data) return; + + const ref = CidRefStore.tryParseRef(data); + let tokens: Token[]; + + if (ref) { + // New path — fetch from IPFS. + tokens = await this.cidRefStore.fetchJson(ref); + } else { + // Legacy path — inline JSON (pre-refactor wallet data). + tokens = JSON.parse(data); + } + + this.mergePendingTokens(tokens); +} +``` + +**Write path is ONE-WAY:** always write CID-ref. On first write after upgrade, the legacy inline blob is replaced with a ref. The legacy data migrates opportunistically through normal wallet activity. + +**Caveats:** +- A user who reads but never writes keeps legacy format forever. That's fine — reads still work. +- A legacy blob > 1 KiB is tolerated on read (the rule only binds writes). +- Rolling back the SDK after the refactor ships means the old SDK reads a CID-ref JSON string and tries `JSON.parse` → gets `{v:1,cid:...,...}` instead of the expected token array → crash. **Downgrade is breaking.** This matches the existing OpLog-schema migration sequencing (documented in PROFILE-OPLOG-SCHEMA.md §7.4). + +--- + +## §7 Pin lifecycle — never-unpin v1 + +When a CID-ref is overwritten with a new ref, the old CID becomes an orphan in the wallet's IPFS store. This refactor **does not unpin orphans**. Rationale: + +1. **Simpler.** Pin/unpin timing races with replication. A premature unpin on one device while another is still replicating the old entry = data loss. +2. **Safer.** Orphan data is cost (disk space), not correctness. Users have disk space; they don't have recoverability from premature GC. +3. **Consistent.** UXF bundles already follow this policy (see PROFILE-AGGREGATOR-POINTER-ARCHITECTURE §9 superseded-bundle retention). + +**Storage cost estimate:** a wallet writing 1000 messages will accumulate ~1000 orphan message CIDs over time. At ~300 bytes each, ~300 KB total orphan cost per 1000 messages. Acceptable. + +**Phase 2 feature:** operator-triggered GC. A background scan reads all OpLog refs, collects currently-referenced CIDs, compares to a pin ledger tracking `(key, cid, firstPinnedAt)`, and unpins CIDs not referenced for > 7 days.

Event Model + +### 4.1 Sphere Events Related to Storage + +The SDK emits events via `this.deps!.emitEvent(type, data)` (delegated to Sphere's event emitter): + +| Event | Emitted By | When | Payload | +|-------|-----------|------|---------| +| `sync:started` | PaymentsModule._doSync() | Sync begins | `{ source: 'payments' }` | +| `sync:completed` | PaymentsModule._doSync() | Sync finishes | `{ source: 'payments', count }` | +| `sync:error` | PaymentsModule._doSync() | Sync fails | `{ source, error }` | +| `sync:provider` | PaymentsModule._doSync() | Per-provider sync result | `{ providerId, success, added, removed, error? }` | + +### 4.2 TokenStorageProvider Events (StorageEvent) + +Providers emit these via `onEvent()` callback: + +| Event Type | Emitted By | Purpose | +|-----------|-----------|---------| +| `storage:saving` | Before save | UI loading indicator | +| `storage:saved` | After save | UI refresh | +| `storage:loading` | Before load | UI loading indicator | +| `storage:loaded` | After load | UI refresh | +| `storage:error` | On failure | Error display | +| `storage:remote-updated` | Push notification (IPNS subscription / OrbitDB) | Triggers debounced sync | +| `sync:started` | Before sync | UI indicator | +| `sync:completed` | After sync | UI refresh | +| `sync:conflict` | During merge | Conflict notification | +| `sync:error` | On sync failure | Error display | + +### 4.3 Push-Based Sync Trigger + +PaymentsModule subscribes to `storage:remote-updated` events from all token storage providers (line 4357). When this event fires: +1. A debounced sync is triggered via `debouncedSyncFromRemoteUpdate(providerId, eventData)` +2. The sync calls `provider.sync(localData)` which merges local and remote state +3. The UI receives `sync:completed` and refreshes + +For the Profile system, OrbitDB replication events should emit `storage:remote-updated` to trigger this same debounced sync flow. The existing mechanism is provider-agnostic — the `ProfileTokenStorageProvider` just needs to emit the right event. + +--- + +## 5. Backward Compatibility Risks + +### 5.1 Synchronous vs Asynchronous Behavior + +**Risk: `setIdentity()` is synchronous.** Both `IndexedDBStorageProvider` and `IndexedDBTokenStorageProvider` implement `setIdentity()` as a synchronous method (just stores the identity object in memory). If `ProfileStorageProvider.setIdentity()` needs to open an OrbitDB connection or perform async initialization, this breaks the contract. + +**Mitigation:** Keep `setIdentity()` synchronous (store identity in memory). Defer OrbitDB connection to the `connect()` / `initialize()` call. + +### 5.2 Key Scoping Logic + +**Risk: `getFullKey()` auto-prefixing.** `IndexedDBStorageProvider.getFullKey()` (line 261) checks whether a key is in `STORAGE_KEYS_ADDRESS` values and auto-adds the address prefix. This is a hardcoded check against the known enum values. If `ProfileStorageProvider` implements a different key-mapping scheme (e.g., dotted notation like `addr1.pendingTransfers`), all key lookups must be consistent. + +**Mitigation:** The `ProfileStorageProvider` should implement the same `getFullKey()` logic, mapping from existing flat keys to Profile dotted keys internally. Callers must not see any difference. + +### 5.3 Write Ordering and Consistency + +**Risk: Read-after-write during wallet creation.** `Sphere.create()` writes keys sequentially (mnemonic, derivation path, base path, etc.) then reads them back during `loadIdentityFromStorage()`. If the Profile provider buffers writes (write-behind) or depends on OrbitDB replication, the read-back may fail. + +**Mitigation:** Local writes must be immediately readable from the local cache before OrbitDB persistence. The write-behind model used by `IpfsStorageProvider` (save returns immediately, flush is async) is the correct pattern. The `ProfileStorageProvider` should maintain an in-memory write buffer that is always consulted during reads. + +### 5.4 `clear()` Semantics + +**Risk: Full clear vs prefix clear.** `Sphere.clear()` calls `storage.clear()` with no prefix — this must wipe ALL keys. `PaymentsModule` never calls `storage.clear()` — it only reads/writes individual keys. If `ProfileStorageProvider.clear()` does not also clear the OrbitDB database, a subsequent `Sphere.init()` on the same device would find no local data but OrbitDB still has the old profile, leading to ghost wallet recovery. + +**Mitigation:** `clear()` must: (1) clear local cache, (2) optionally tombstone/delete OrbitDB entries, (3) ensure `Sphere.exists()` returns false afterward. The Profile Architecture specifies this in the migration cleanup (Section 7.6 step 5). + +### 5.5 `exists()` Check Without Identity + +**Risk: `Sphere.exists(storage)` is called before `setIdentity()`.** It checks for `mnemonic` and `master_key` global keys. The `ProfileStorageProvider` must support reads of global keys before identity is set. + +**Mitigation:** Global keys must be accessible without address scoping. The Profile schema stores these under `identity.mnemonic` etc., and the key-mapping logic in `get()` must handle the pre-identity state. + +### 5.6 TrackedAddresses Dedicated Methods + +**Risk: `saveTrackedAddresses()` / `loadTrackedAddresses()` are dedicated interface methods**, not generic `get/set`. The `IndexedDBStorageProvider` implements them as thin wrappers over `set(TRACKED_ADDRESSES, JSON.stringify(...))` and `get(TRACKED_ADDRESSES)`. The `ProfileStorageProvider` must implement these same methods. + +**Mitigation:** Implement as wrappers that map to `addresses.tracked` in the Profile. + +### 5.7 TokenStorageProvider `save()` Is Called Very Frequently + +PaymentsModule calls `this.save()` after almost every token state change (send, receive, split, resolve, etc. — over 30 call sites). If `ProfileStorageProvider.save()` pins a new CAR file to IPFS on every call, IPFS will accumulate hundreds of CIDs per session. + +**Mitigation:** The `IpfsStorageProvider` already solves this with a write-behind buffer and debounced flush (2-second coalesce window). The `ProfileTokenStorageProvider` must use the same pattern: accept writes immediately, debounce the actual IPFS pin + OrbitDB update. + +### 5.8 History Store: Optional Methods + +The `addHistoryEntry()`, `getHistoryEntries()`, etc. are optional on the `TokenStorageProvider` interface. `PaymentsModule` checks for their existence before calling. The `ProfileTokenStorageProvider` should implement all optional history methods to maintain feature parity with `IndexedDBTokenStorageProvider`. If it does not, history entries will only be serialized in the `_history` array inside TXF data (less efficient, no dedup store). + +--- + +## 6.

OrbitDB's own signature (on `hash(key || cborBytes)`) covers the entire envelope. + +### 2.3 Size budget + +Typical entry (with 200-byte encrypted token-ref payload): + +``` +CBOR envelope overhead: ~40 bytes (field names + type tags) +Encrypted payload: ~200 bytes +----------------------------------------- +Total entry size: ~240 bytes +``` + +PROFILE-ARCHITECTURE.md §4.5 estimates 100–500 bytes per entry; the envelope adds 40 bytes of overhead, landing at 140–540 bytes. Acceptable. + +--- + +## §3 Encryption Boundary + +Encryption applies to the `payload` field only. The envelope metadata (`v`, `type`, `originated`, `ts`) is **plaintext**. + +### 3.1 Rationale + +- **Replication can validate without key access.** A peer replicating the OpLog can check `v === 1`, assert `originated ∈ {'user','system','replicated'}`, and enforce `downgradeForReplication` — without ever decrypting the payload. +- **OpLog readers can index by type.** Phase 2 features (selective sync, type-filtered recovery) can scan the OpLog for `type === 'invoice_mint'` entries without decrypting non-matching entries. +- **Timestamp ordering is correct without decrypt.** OrbitDB's Lamport clock is sufficient for CRDT merge, but `ts` is useful for UI sort — visible timestamps enable this. + +### 3.2 Threat model + +The envelope's plaintext metadata leaks: +- **Action types** — an observer sees the wallet did `token_send`, `swap_deposit`, etc. +- **Timing pattern** — wall-clock timestamps of activity. + +These are acceptable given: +- The observer already sees OpLog entries appearing (from PubSub / Nostr relay observation). +- Activity timing was already inferrable from entry-count rate. +- The existing IPFS content-addressed model already leaks CIDs (and thus bundle membership counts via pinned-bundle observation). + +Full metadata privacy is a Phase 2 feature (onion routing, mixnet, timing-obfuscated publish) out of scope for this design. + +### 3.3 Encryption primitive + +`payload` uses the existing `encryptProfileValue` / `decryptProfileValue` primitives (AES-256-GCM, wallet-derived key from `profile/encryption.ts` or equivalent). The envelope itself is NOT re-encrypted — only the payload. + +### 3.4 Replication-ingress attack surface (post-steelman) + +The `originated` tag is the load-bearing security field. A peer that can get a write accepted by OrbitDB's access controller will author envelopes of its choice — including `originated: 'user'` forgery attempts. Without defense-in-depth, any local code path that reads envelopes and trusts the stored tag would treat peer forgery as authentic local activity. + +**Authentication boundary: `OrbitDbAdapter.getEntry()` is the choke point.** + +Default behavior (post-steelman): + +```typescript +// Default — replicated-downgrade enforced: +const envelope = await adapter.getEntry(key); +// → envelope.originated is ALWAYS 'replicated' (or v=0 legacy sentinel) + +// Explicit trust — requires BOTH the caller's signal AND local authorship: +const envelope = await adapter.getEntry(key, { trustLocalClaim: true }); +// → envelope.originated is the stored tag IFF the key was written via +// putEntry in THIS session AND no replication event has fired since. +``` + +The adapter maintains a session-scoped `localAuthoredKeys: Set` that: +- Gains an entry on every local `putEntry(key, ...)` call. +- Is CLEARED entirely on every `onReplication` event (conservative: a peer may have overwritten any key via OrbitDB's LWW-per-key CRDT). +- Is CLEARED on `close()` / session end. + +A key written in session N cannot be trusted across sessions — a remote peer may have overwritten it (LWW) while we were offline. Local writes are always re-stamped on next write, so long-lived trust is not required. + +**What this defeats:** +- Peer publishes `{originated: 'user', type: 'token_send', ...}` → default `getEntry` returns `originated: 'replicated'`. Local code that conditionally trusts 'user' origins does not conditionally trust this envelope. +- Peer replays a forgery after a local write → the replication event fires → `localAuthoredKeys` clears → subsequent trusted reads downgrade again. +- Peer crafts legacy-shaped CBOR (bare `Uint8Array`) at replication ingress → `decodeAndDowngradeReplicated` rejects with `OpLogEntryCorrupt` (legacy format is strictly local synthesis). + +**What this does NOT defeat** (out-of-scope for this layer): +- An attacker with local code execution — they can call `markLocallyAuthored()` directly or bypass the adapter entirely. +- A compromised OrbitDB identity used to write from a trusted device — indistinguishable from a legitimate local write. +- Timing attacks inferring wallet activity from replication-event timing. + +### 3.5 DoS guards + +CBOR decode of untrusted replicated data is protected by: +- `MAX_ENVELOPE_BYTES` = 256 KiB (pre-decode byte cap — rejects 4 GB-declared byte strings before allocation). +- `MAX_PAYLOAD_BYTES` = 128 KiB (post-decode payload cap). +- Strict shape check: envelope MUST contain exactly the five known fields `(v, type, originated, ts, payload)` — extra fields rejected. +- `MIN_PLAUSIBLE_TS` = 2020-01-01 UTC: real envelopes must carry ts >= this value. `ts = 0` is reserved for the legacy sentinel; `ts < MIN_PLAUSIBLE_TS` is treated as corruption. + +--- + +## §4 Validation + +Every envelope read from OrbitDB MUST be validated BEFORE the caller sees the decoded object: + +```typescript +function validateEnvelope(e: unknown): OpLogEntryEnvelope { + // 1. Structural shape check + if (typeof e !== 'object' || e === null) throw CORRUPT; + const r = e as Partial; + + // 2. Schema-version gate — unknown versions fail-closed + if (r.v !== OPLOG_ENTRY_SCHEMA_VERSION) { + throw CORRUPT({ reason: 'schema_version_mismatch', got: r.v }); + } + + // 3.

That stays with the calling module. + +--- + +## §7 Backward Compatibility + +### 7.1 Existing wallets + +Existing wallets have OrbitDB databases full of **raw opaque `Uint8Array`** values (not CBOR envelopes). When upgraded SDK reads these, `CBOR.decode` will either: +- Throw (malformed CBOR) — trigger a migration-detection fallback. +- Succeed with a non-envelope shape — `validateEnvelope` rejects. + +**Migration strategy (§7.2):** the adapter implements a LEGACY READ PATH that detects non-envelope values and wraps them on-the-fly in a synthetic envelope with: + +```typescript +{ + v: 1, + type: 'cache_index', // conservative default: treat unknown legacy as system + originated: 'system', + ts: 0, // unknown origin time + payload: , +} +``` + +Legacy entries are NEVER WRITTEN BACK — on subsequent modifications, the caller writes a fresh envelope. The OpLog thus gradually migrates through normal wallet activity. + +### 7.2 Detection heuristic + +Attempt CBOR decode. If: +- It throws → legacy (treat as wrapped). +- It succeeds but produces a non-object / missing `v` field → legacy. +- It produces `{ v: 1, type, originated, ts, payload }` with valid types → envelope. +- It produces `{ v: N }` with N > 1 → forward-compat unknown version → CORRUPT, refuse to read. + +The heuristic has a tiny false-positive probability (a raw byte sequence that happens to decode as a valid CBOR map with `v: 1` and the exact field names). Upper bound: < 2^-80 for any realistic payload. Acceptable. + +### 7.3 Adapter gradual adoption + +The `OrbitDbAdapter` exposes BOTH APIs during migration: + +```typescript +// Legacy (opaque bytes — preserved for backward compat) +async put(key: string, value: Uint8Array): Promise; +async get(key: string): Promise; + +// New (structured envelope — callers migrate one module at a time) +async putEntry(key: string, entry: OpLogEntryEnvelope): Promise; +async getEntry(key: string, opts?: { trustLocalClaim?: boolean }): Promise; +``` + +Once all callers have migrated, the legacy methods are deprecated in a single follow-up (not this design doc's scope). + +### 7.4 Deployment sequencing ⚠️ LOAD-BEARING + +**Strict requirement: all devices sharing an OrbitDB instance MUST upgrade to the new SDK before ANY of them write envelopes.** + +The migration is asymmetric by design: + +| Writer | Reader | Outcome | +|--------|--------|---------| +| Old SDK (raw bytes) | Old SDK | ✓ raw round-trip (pre-schema behavior) | +| New SDK (envelope) | New SDK | ✓ envelope round-trip with downgrade enforcement | +| Old SDK (raw bytes) | New SDK | ✓ legacy fallback wraps raw Uint8Array CBOR as synthetic v=0 envelope | +| **New SDK (envelope)** | **Old SDK** | ❌ **BREAKS** — old SDK passes envelope bytes to `decryptProfileValue`, which interprets CBOR header bytes as AES-GCM nonce → `DECRYPTION_FAILED`. Wallet sees data as missing. | + +**Consequence:** if a user runs the new SDK on one device and the old SDK on another, the second device breaks the moment the first writes anything. Multi-device wallets MUST coordinate upgrades. + +**Deployment patterns:** + +1. **Coordinated fleet upgrade (simplest):** release the new SDK with a version-gate on an external signal (e.g., operator-controlled feature flag) and flip it after all known devices have updated. Keep the new SDK in legacy mode (reads only, does not write envelopes) until the flag flips. Not implemented in this schema — would require a per-adapter config flag. + +2. **Dual-write transition window (future hardening):** during a deprecation period, write BOTH formats under parallel keys (`key` = raw legacy, `key.v1` = envelope) and have new readers prefer the envelope form. After all old SDKs are decommissioned, dual-writing can stop. Not in scope for the initial rollout. + +3. **Big-bang upgrade (current default):** ship the new SDK with clear release notes: "all devices must upgrade together". Acceptable for early adopters. NOT acceptable once there's a production user base with multi-device wallets. + +**Recommendation:** production deployment SHOULD gate the envelope-write path on an explicit `enableEnvelopeWrites: boolean` configuration flag, defaulting to `false` in release builds until a fleet-upgrade window is complete. + +### 7.5 Symmetric capability probe + +`ProfileStorageProvider.supportsEnvelopes()` runs a one-shot probe on first access: both `putEntry` AND `getEntry` must exist on the adapter, or NEITHER. An asymmetric adapter (one method but not the other) throws `PROFILE_NOT_INITIALIZED` at the first write. This prevents the silent-corruption mode where an adapter writes envelopes but reads raw bytes (or vice versa) — a scenario that would otherwise leave unreadable data on disk with no error at write time. + +--- + +## §8 Integration with Pointer Layer + +The pointer layer publishes OpLog head CIDs to the aggregator. It does NOT read or write individual OpLog entries — it operates on the OrbitDB manifest CID. + +The envelope is load-bearing for the pointer layer in one place: **recovery-time validation**. When `ProfilePointerLayer.recoverLatest()` returns a CID and the caller fetches the bundle, the replay of OpLog entries into the local OpLog passes through the replication ingress path (§5.2). `downgradeForReplication` fires, `assertOriginTagReplicated` runs, and the newly-joined entries carry `originated: 'replicated'`. + +This closes the security gap that motivated this schema: a malicious peer publishing a bundle whose entries claim `originated: 'user'` will have those claims OVERWRITTEN by the ingress downgrade. + +--- + +## §9 Open questions (resolved) + +| # | Question | Resolution | +|---|----------|-----------| +| 1 | Encrypt envelope metadata? | NO — plaintext metadata enables non-decrypting validation + indexing; threat model accepts the leak. | +| 2 | Sign envelope independently of OrbitDB? | NO — OrbitDB's own entry signature covers the envelope bytes; no second layer needed. | +| 3 | CBOR vs JSON vs protobuf? | CBOR — determinism, binary compactness, IPLD alignment, native bytes. | +| 4 | Schema version gating behavior? | Fail-closed on unknown `v`. Forward-compat requires explicit support, not silent success. | +| 5 | Timestamp source (local vs CRDT clock)? | Wall-clock `ts` preserved across replication — Lamport clock is for CRDT merge, `ts` is for UI. | +| 6 | Migration approach — big-bang vs gradual? | Gradual via legacy read fallback. Avoids a one-shot rewrite that could fail mid-flight. | + +--- + +## §10 Non-scope (future work) + +- **Encrypted metadata** — phase 2 if privacy threat model changes. +- **Multi-version envelope** — V2 may add retention hints, sub-type, payload compression flags. Additive-only changes keep v=1 readers compatible; breaking changes require v bump + coordinated migration. +- **Schema registry** — a canonical list of `type` → payload-schema bindings (for type-safe module writers) is deferred to the W11 work. +- **Rename `type` → `kind`?** — Keep `type` per SPEC §10.2.3.

Architectural Risks + +### FINDING 1.1 -- Nametag Representation Mismatch (CRITICAL) + +**Observation:** The TASK.md states (line 55-56) that `nametags[]` in a token are "each ... itself a full Token -- recursive" and the DAG model assumes nametag tokens are full token sub-DAGs that can be shared. However, the actual `TxfToken` type at `/home/vrogojin/uxf/types/txf.ts` line 21 defines `nametags?: string[]` -- nametags are plain strings, not embedded token objects. The `NametagData` type (line 117-123) does contain a `token: object` field, but this lives in `TxfStorageData._nametags`, not inside `TxfToken.nametags`. + +**Impact:** The entire nametag deduplication argument in TASK.md (Section "Key Deduplication Targets" item 2: "the same nametag token may appear in dozens of other tokens") is predicated on a data model that does not exist in the current codebase. Nametag tokens are not recursively embedded in `TxfToken`. This means one of the four claimed deduplication targets is phantom. + +**Resolution:** Either (a) the TASK.md must be corrected to reflect the actual TxfToken structure, where nametags are string references, or (b) UXF must be designed against the `ITokenJson` format from `state-transition-sdk` (not TxfToken), which may have recursive nametag embedding. Clarify which source-of-truth token structure UXF operates on. If it is `ITokenJson`, provide its full type definition in the spec. + +--- + +### FINDING 1.2 -- Instance Chain Branching is Undefined (CRITICAL) + +**Observation:** The instance chain model (TASK.md lines 146-223) assumes a singly-linked chain (newest-to-oldest). But the spec never addresses what happens when two independent agents create alternative instances of the same element concurrently. For example: Agent A creates a consolidated proof referencing element X, and Agent B creates a ZK proof also referencing element X. Both claim to be the head of X's instance chain with X as their predecessor. + +**Impact:** This creates a fork in the instance chain. The "instance chain index" (line 223) maps each element hash to "the head of its instance chain," but with two competing heads, the index is undefined. The `merge()` operation (line 281) must combine two packages, potentially with conflicting instance chain heads for the same element. + +**Resolution:** Define a merge strategy for conflicting instance chains. Options: (a) instance chains become DAGs, not linear chains (but this breaks the "singly-linked" invariant); (b) define a deterministic ordering (e.g., by content hash) to pick a canonical head; (c) allow multiple heads and treat instance chains as a set rather than a list. This must be specified before implementation. + +--- + +### FINDING 1.3 -- Garbage Collection with Shared Elements is NP-Hard Adjacent (MAJOR) + +**Observation:** TASK.md scope item 1 mentions "garbage collection" for the element pool. Since elements are shared across tokens, removing a token requires reference counting or graph traversal to determine if each element is still referenced by another token. The spec does not define the GC algorithm. + +**Impact:** Naive reference counting fails with instance chains (an instance may reference elements also referenced by other instance chains). Full graph traversal from all manifest roots on every `removeToken()` is O(total_elements * tokens), which is expensive. For a wallet with 1000 tokens averaging 50 elements each, that is 50,000 nodes to traverse per removal. + +**Resolution:** Specify the GC algorithm explicitly. Options: (a) mark-and-sweep from all manifest roots (simple but slow); (b) reference counting with instance chain awareness; (c) lazy GC with periodic compaction (pragmatic for a wallet use case where pools are small). Note that the `removeToken` API returns `UxfPackage`, implying it produces a new package -- is the old package's pool left dirty? + +--- + +### FINDING 1.4 -- Circular Reference Potential in DAG (MAJOR) + +**Observation:** TASK.md line 69 states "An element from one token may contain (reference) subelements that belong to a different token -- this is natural and expected in the DAG model." Combined with the recursive nametag claim, consider: Token A references nametag Token B in its transaction. Token B is itself a full token in the manifest. If Token B's genesis references a unicity certificate that happens to be shared with Token A's inclusion proof, there is no true circularity (just shared leaves). However, the spec never explicitly forbids circular references at the element level, nor does it specify cycle detection during reassembly. + +**Impact:** If a bug in deconstruction or a malicious element pool creates a cycle (element X references element Y which references element X), reassembly would infinite-loop. Since the spec claims reassembly is "recursive traversal," this is an unbounded recursion risk. + +**Resolution:** Add an explicit invariant: "The element pool MUST be a DAG (no cycles). Reassembly implementations MUST track visited nodes and terminate with an error if a cycle is detected." Include this in the `verify()` operation. + +--- + +### FINDING 1.5 -- Content-Addressing Overhead for Small Elements (MINOR) + +**Observation:** TASK.md proposes that every node at every depth is independently content-hashed. For small elements like a `TxfAuthenticator` (4 string fields, ~200 bytes) or a `TxfState` (2 string fields, ~100 bytes), the overhead of a CID (36+ bytes for SHA-256 multihash + codec) plus the element header (`[repr, sem, kind, predecessor]`) may exceed 30-50% of the element's actual content. + +**Impact:** For tokens with few shared elements (a solo user's wallet where every token has unique authenticators and states), UXF could be larger than raw TXF. The "Size efficiency" constraint (line 341) says UXF should be "significantly smaller" but this only holds when sharing is common. + +**Resolution:** Define a threshold below which elements are inlined rather than stored as separate DAG nodes. For example, elements under 128 bytes could be embedded directly in their parent. This is standard practice in IPLD (inline CIDs for small blocks). Add a benchmark for the worst case (no sharing) to acceptance criteria. + +--- + +## 2. Integration Concerns + +### FINDING 2.1 -- TXF to UXF Migration Path is Absent (CRITICAL) + +**Observation:** The existing codebase stores tokens as `TxfStorageData` (a flat JSON object keyed by `_` containing `TxfToken` objects). The IPFS storage provider uploads this as a single JSON blob. UXF proposes a fundamentally different storage model (DAG of content-addressed elements). TASK.md does not specify: +- How existing wallets migrate from TxfStorageData to UXF packages +- Whether UXF replaces `TxfStorageData` entirely or coexists +- Whether `TokenStorageProvider` interface changes +- Whether `IpfsStorageProvider` is modified or replaced + +**Impact:** `PaymentsModule.ts` (the 88KB main consumer) calls `parseTxfStorageData()` and `buildTxfStorageData()` extensively. Every load/save cycle goes through these functions. Changing the storage format without a migration strategy risks breaking all existing wallets. + +**Resolution:** Define three phases: (1) UXF as a library that can ingest/emit `ITokenJson`/`TxfToken`, independent of storage; (2) a new `UxfStorageProvider` implementing `TokenStorageProvider` that internally uses UXF but exposes the same interface; (3) migration logic that reads existing TxfStorageData and converts to UXF on first load. Phase 1 should be the MVP. + +--- + +### FINDING 2.2 -- IPFS Integration Model Mismatch (MAJOR) + +**Observation:** The existing IPFS integration (`/home/vrogojin/uxf/impl/shared/ipfs/`) uses a simple model: serialize entire `TxfStorageData` as JSON, upload as a single IPFS object, get a CID, publish via IPNS. It uses `FormData` with `api/v0/add` (line 151 of `ipfs-http-client.ts`). + +TASK.md proposes IPLD DAG nodes with CID-based links between elements. This requires `dag-cbor` codec, `dag-put` API calls, and CAR file exports -- none of which exist in the current HTTP client. The current client does not even import or use IPLD libraries. + +**Impact:** The "IPFS/IPLD alignment" scope item implies the current IPFS integration is compatible. It is not. A new DAG-native client layer would be required, or the IPLD alignment becomes a future aspiration rather than an implementation target. + +**Resolution:** Either (a) scope down Phase 1 to use IPFS as a dumb blob store (upload the UXF package as a single serialized object, like TXF does today) and add true IPLD DAG integration later; or (b) acknowledge that a new `IpldClient` class is needed alongside `IpfsHttpClient`, with `dag-cbor` encoding and per-node `dag/put` calls. Option (b) has significant performance implications (N HTTP calls for N nodes vs. 1 call for a blob). + +--- + +### FINDING 2.3 -- Bundle Size Impact of IPLD Dependencies (MAJOR) + +**Observation:** TASK.md scope item 4 lists "IPLD-compatible DAG export" and "CBOR and JSON serialization." This implies dependencies on `@ipld/dag-cbor`, `multiformats`, `@ipld/car`, and potentially `@ipld/dag-json`. The current `package.json` has none of these. + +**Impact:** `@ipld/dag-cbor` + `multiformats` together add approximately 50-100KB minified to the browser bundle. The SDK already has `@noble/hashes` and `@noble/curves` as crypto dependencies. Adding IPLD stack could increase bundle size by 15-25%, which matters for the browser entry point. The tsup multi-entry-point build (noted in CLAUDE.md as causing singleton duplication issues) would duplicate these dependencies across bundles. + +**Resolution:** Make IPLD dependencies optional/lazy-loaded. The core UXF deconstruction/reassembly should work with a pluggable hash function (SHA-256 from `@noble/hashes`, already present) and a minimal CID implementation. True IPLD export should be a separate entry point (`@unicitylabs/sphere-sdk/uxf/ipld`). This keeps the main bundle lean. + +--- + +### FINDING 2.4 -- TxfToken vs ITokenJson Ambiguity (MAJOR) + +**Observation:** TASK.md references both `ITokenJson` (from `state-transition-sdk`) and `TxfToken` (from sphere-sdk). These are different types with different structures. For example: +- `TxfToken.nametags` is `string[]` +- `ITokenJson.nametags` (per TASK.md line 55) is recursive token objects +- `TxfToken.transactions[].data` is `Record` +- `ITokenJson` transactions have typed `MintTransactionData`/`TransferTransactionData` +- `TxfToken` has `_integrity` metadata not present in `ITokenJson` + +The spec says UXF must "ingest and emit standard `ITokenJson` / CBOR v2.0 tokens" (line 337) but also references TXF structures throughout. The `ingest()` function takes `Token` (the sphere-sdk type), not `ITokenJson`. + +**Resolution:** Define the canonical input/output types explicitly. If UXF operates on `ITokenJson` from state-transition-sdk, say so and define the mapping. If it operates on `TxfToken`, the nametag DAG claims are invalid. The API signatures in scope (lines 275-286) use `Token` which is the sphere-sdk UI type that contains `sdkData: string` (serialized JSON). This means `ingest` would need to parse `token.sdkData` to get the actual token structure -- adding another layer of indirection. + +--- + +## 3. Specification Gaps + +### FINDING 3.1 -- Element Taxonomy is Not Defined (CRITICAL) + +**Observation:** TASK.md scope item 1 lists "Element taxonomy -- formal definition of each element type" but the body of the spec never actually defines it. We do not know: +- Which fields of `TxfGenesis` become separate elements vs. inline data? +- Is `TxfGenesisData` one element, or is `coinData` a separate element? +- Is each `TxfMerkleStep` a separate element, or is the entire `merkleTreePath` one element? +- Is `unicityCertificate` (a hex-encoded CBOR string in TxfToken) decoded and decomposed, or stored as an opaque blob? +- Is `TxfState` (predicate + data) one element or two? + +**Impact:** Without this taxonomy, it is impossible to implement `ingest()` or evaluate deduplication effectiveness. The granularity of decomposition determines both the deduplication ratio and the overhead. + +**Resolution:** Produce a complete element taxonomy table before implementation. For each element type: name, parent element, fields that are child references vs. inline data, expected size range, sharing likelihood. This is the single most important pre-implementation deliverable. + +--- + +### FINDING 3.2 -- Pending Transactions and Outbox are Unaddressed (CRITICAL) + +**Observation:** `TxfStorageData` contains `_outbox` (pending transfers), `_mintOutbox` (pending mints), `_tombstones` (spent markers), and `_sent` (completed transfers). These are wallet-operational metadata, not part of the token's cryptographic structure. TASK.md never mentions how these are represented in UXF. + +The spec says UXF is a "packaging format for storing and exchanging Unicity token materials" but the actual storage format (`TxfStorageData`) is more than just tokens -- it is a complete wallet state snapshot. If UXF replaces `TxfStorageData` as the storage format, it must handle these fields. If UXF is only for exchange (not storage), the scope must be clarified. + +**Impact:** The `PaymentsModule` depends on `_outbox` for tracking in-flight transfers and `_tombstones` for preventing double-spend. Without these in UXF, it cannot serve as a storage backend. + +**Resolution:** Define whether UXF is: (a) a pure token exchange format (in which case operational metadata lives outside UXF and the "storage" use case requires a wrapper); or (b) a complete wallet state format (in which case _outbox, _tombstones, _mintOutbox, _nametags, _history must be part of the package envelope). The "Package Envelope (version, metadata)" in the diagram (line 76) needs to be specified. + +--- + +### FINDING 3.3 -- Deterministic Serialization Rules are Unspecified (MAJOR) + +**Observation:** Design constraint 4 (line 340) requires "identical logical content must produce identical byte sequences." This is essential for content-addressable storage. However, the spec does not define: +- CBOR canonical form (RFC 7049 Section 3.9, or RFC 8949 deterministic encoding?) +- JSON canonical form (key ordering? number formatting?) +- How hex strings are normalized (lowercase? uppercase? mixed allowed?) +- Whether the `unicityCertificate` field (already hex-encoded CBOR) is decoded and re-encoded deterministically, or kept as-is + +The existing `normalizeSdkTokenToStorage()` function converts bytes to hex strings, but does not enforce key ordering or other deterministic properties. + +**Resolution:** Choose a canonical encoding (RFC 8949 deterministic CBOR is recommended for new formats). Specify normalization rules for all string fields. Add a "canonicalize" step to `ingest()` that normalizes before hashing. Define whether hex-encoded opaque blobs (like `unicityCertificate`) are decoded or treated as raw bytes. + +--- + +### FINDING 3.4 -- "Version" Semantics are Overloaded (MAJOR) + +**Observation:** The versioning model defines four different version concepts: +1. Token-level version (e.g., `"2.0"`) +2. Representation version (encoding format, `repr` in header) +3. Semantic version (protocol rules, `sem` in header) +4. TxfMeta.version (storage data version counter, incremented on merge) +5. TxfMeta.formatVersion (`"2.0"`) + +The element header has `representation` and `semantics` as uints, but existing TxfToken uses `version: '2.0'` as a string. Are these the same versioning scheme? When TASK.md says "v1 semantics" vs "v2 semantics," does v1 correspond to the pre-existing format and v2 to UXF? This is never defined. + +**Resolution:** Create a version mapping table. Define what semantic version 1 means concretely (which validation rules, which hash algorithm). Define the relationship between `TxfToken.version: '2.0'` and element-level `semantics: uint`. If semantic version 1 = everything that exists today, say so explicitly. + +--- + +### FINDING 3.5 -- ZK Proof Substitution is Aspirational (MINOR) + +**Observation:** TASK.md describes ZK proof substitution (lines 172-183) and includes it in acceptance criteria (criterion 13, line 362). However, no ZK proof system exists in the current codebase or dependencies. There is no `ZkProofVerifier`, no ZK circuit, and no ZK library in `package.json`. The acceptance criterion requires "a valid reassembled token under ZK verification." + +**Impact:** This acceptance criterion is impossible to satisfy without building or integrating a ZK proof system, which is a major undertaking orthogonal to UXF format design. + +**Resolution:** Move ZK proof substitution to "Future Work" or "Phase 2." The instance chain mechanism should support it by design (the architecture is sound), but the acceptance criterion should test instance chains with a mock alternative instance type, not actual ZK proofs. + +--- + +### FINDING 3.6 -- Proof Consolidation Semantics are Undefined (MAJOR) + +**Observation:** TASK.md describes "proof consolidation" where multiple individual unicity proofs are merged into "a single subtree of the aggregator's Sparse Merkle Tree" (line 159). The acceptance criterion (12) requires this to produce "a valid, smaller element." But: +- How is a consolidated SMT subtree constructed? This requires knowledge of the aggregator's tree structure. +- Is this an operation the client can perform locally, or does it require the aggregator? +- The current `InclusionProof` contains a `merkleTreePath` from leaf to root. A "consolidated" proof that covers multiple leaves would have a different structure -- what is it? + +**Impact:** Without defining the consolidated proof format, `consolidateProofs()` cannot be implemented. + +**Resolution:** Either (a) defer proof consolidation to Phase 2 with the aggregator team, or (b) define the consolidated proof format explicitly, including how multiple Merkle paths are merged into a shared subtree and what the verification algorithm is. + +--- + +## 4. Performance Concerns + +### FINDING 4.1 -- DAG Node Count Explosion (MAJOR) + +**Observation:** Consider a wallet with 100 tokens, each with 5 transactions. Each transaction contains: `inclusionProof` (which contains `authenticator`, `merkleTreePath` with ~20 steps, `unicityCertificate`, `transactionHash`), `predicate`, `data`, `previousStateHash`, `newStateHash`. Plus genesis with similar structure, plus state. + +Per token: ~1 (root) + 1 (genesis) + 1 (genesis data) + 1 (genesis proof) + 1 (authenticator) + 20 (merkle steps) + 1 (cert) + 5 * (1 tx + 1 proof + 1 auth + 20 steps + 1 cert) + 1 (state) = ~140 elements minimum per token. With 100 tokens: 14,000 elements. Even with 50% deduplication (optimistic): 7,000 unique elements. + +Each element needs: content hash computation (SHA-256), CID encoding, pool lookup, header encoding. On `ingest()` of a single token with 5 transactions: ~140 hash computations and pool lookups. + +**Impact:** For `assembleAll()` (not in API but implied by `getTokens()`): reassembling 100 tokens means 14,000 DAG traversals. If each traversal is a Map lookup (O(1)), this is fast in memory. But if the pool is persisted to IndexedDB (as implied by browser use), each lookup is an async IDB get. 14,000 async IDB reads would take seconds. + +**Resolution:** Define storage tiers: (a) in-memory pool for active session (fast), (b) serialized pool for persistence (single read/write of entire pool, not per-element). The pool should never require per-element async IO. Add the node count estimate to benchmarks. + +--- + +### FINDING 4.2 -- Streaming Reassembly is Infeasible with DAG Structure (MAJOR) + +**Observation:** Design constraint 3 (line 339) requires "streaming-friendly -- it should be possible to begin extracting tokens before the entire package is downloaded." But a DAG-structured pool means a token's root may reference elements scattered throughout the serialized pool. Without downloading the entire element pool (or at least the index), you cannot know which elements belong to which token. + +**Impact:** True streaming (process bytes as they arrive) is incompatible with a shared element pool unless elements are topologically sorted and preceded by a manifest. Even then, an element might be referenced by a token whose root hasn't been read yet. + +**Resolution:** Redefine "streaming-friendly" to mean: (a) the manifest is at the beginning of the serialized format, allowing early knowledge of which tokens exist; (b) elements can be lazily resolved (fetched on demand from IPFS by CID) rather than pre-loaded. True byte-level streaming is not feasible with a shared DAG; lazy resolution is the closest achievable property. Alternatively, use CAR format with a deterministic element ordering (manifest first, then BFS traversal of each token's DAG), but acknowledge that cross-token shared elements will be referenced before they are defined in the stream. + +--- + +### FINDING 4.3 -- Instance Chain Index Maintenance Cost (MINOR) + +**Observation:** The instance chain index maps "each element hash to the head of its instance chain." When a new instance is added via `addInstance()`, every element in the chain needs its index entry updated to point to the new head. For a chain of length N, this is O(N) index updates per `addInstance()`. + +**Impact:** For proof consolidation where a single consolidated proof replaces a chain of N individual proofs, the index must update entries for all N predecessors. This is O(N) but N is bounded by the number of transactions (typically small, <100). + +**Resolution:** This is manageable at wallet scale. Document the O(N) cost and note that the index is a convenience structure that can be rebuilt from the pool by scanning all elements. No design change needed, but the cost should be acknowledged. + +--- + +## 5. Security Concerns + +### FINDING 5.1 -- No Element Integrity Verification During Reassembly (CRITICAL) + +**Observation:** The spec says elements are content-addressed (hash is their identifier). During reassembly, an element is fetched from the pool by its hash. But the spec never states that the reassembly algorithm MUST verify that the element's actual content matches its claimed hash. If the pool is corrupted (disk error) or malicious (tampered IPFS node), an element could have been replaced with different content while keeping the same key. + +**Impact:** A malicious actor who controls an IPFS gateway could serve modified element content for a valid CID. The reassembled token would contain corrupted data but appear valid to the reassembly algorithm (which just follows references). Token validation would catch cryptographic inconsistencies, but only if the consumer runs full verification -- and the spec says reassembled tokens should be "indistinguishable from the original" without mentioning mandatory re-verification. + +**Resolution:** Mandate that `assemble()` re-hashes every element fetched from the pool and compares against the expected CID. If any mismatch is found, reassembly fails with an integrity error. This is cheap (SHA-256 is fast) and essential. Add this to the `verify()` operation as well. + +--- + +### FINDING 5.2 -- Instance Chain Poisoning (MAJOR) + +**Observation:** An attacker who can add elements to the pool (e.g., via a `merge()` with a malicious package) can create a fraudulent instance chain entry. For example: the attacker creates an element with `predecessor: hash_of_legitimate_proof` and `kind: "consolidated-proof"`, containing a fabricated proof. The instance chain index would point to this as the head, and `strategy=latest` would select it during reassembly. + +**Impact:** The reassembled token would contain a fake proof. If the consumer does not independently verify the proof against the aggregator, they would accept a forged state transition. + +**Resolution:** Instance chain entries must be validated before being added to the index. At minimum: (a) verify that the new instance's content hash is correct; (b) verify that the predecessor reference points to an existing element; (c) for proof-type instances, verify that the new proof is semantically equivalent to the predecessor (e.g., proves the same state transitions). Criterion (c) requires domain-specific validation and should be a pluggable verifier. + +--- + +### FINDING 5.3 -- SHA-256 Collision Resistance is Sufficient (MINOR) + +**Observation:** TASK.md does not explicitly name the hash function, but references CIDs and SHA-256 (line 315: "SHA-256(pubkey || stateHash)"). SHA-256 provides 128-bit collision resistance, which is well above the threshold for any practical attack. Content-addressable systems like IPFS and Git use SHA-256 successfully. + +**Impact:** No risk. SHA-256 is appropriate. + +**Resolution:** None needed. Explicitly name SHA-256 as the hash function in the spec for clarity, and use the multihash encoding from multiformats for forward-compatibility with future hash upgrades. + +--- + +## 6. Contradictions Within TASK.md + +### FINDING 6.1 -- "Append-Only" vs "Proof Updates" Contradiction (MAJOR) + +**Observation:** Line 30-31 states: "Once an element is added to a token, it cannot be modified or removed." Then immediately: "The sole exception is unicity proofs, which may be updated in place." But the instance chain model (lines 146-148) says "An updated instance is stored as a separate DAG node... The previous instance is never removed." These are contradictory: the first statement says proofs can be "updated in place" (implying mutation), while the instance chain model says updates are append-only (new nodes, old preserved). + +**Resolution:** Remove the "updated in place" language from line 31. Replace with: "The sole exception is unicity proofs, which may have alternative representations added via instance chains (see Versioning Model). The original proof is always preserved." + +--- + +### FINDING 6.2 -- "Flat Element Pool" vs "DAG" Terminology Confusion (MINOR) + +**Observation:** Line 62 says "a shared, flat element pool" and line 109 says "the element pool is a shared DAG." A flat store and a DAG are different concepts. The pool is flat in the sense of being a key-value store (hash -> element), but the elements form a DAG via their references. The text conflates the storage structure (flat) with the logical structure (DAG). + +**Resolution:** Clarify: "The element pool is a flat content-addressed store (hash-to-element mapping). The elements within it form a directed acyclic graph via their child references." + +--- + +### FINDING 6.3 -- API Inconsistency: ingest vs addToken (MINOR) + +**Observation:** The API lists both `ingest(pkg, token)` (line 275-276) and `addToken(pkg, token)` (line 279). Both appear to add a token to a package. The difference is not explained. `ingest` says "deconstruct a self-contained token into elements, deduplicate against the pool, and add/update its manifest entry." `addToken` says "incremental addition." Are these the same operation? + +**Resolution:** Either merge them into one function, or define the difference. If `addToken` is the public API and `ingest` is the internal operation, make that explicit. If `addToken` handles metadata (like updating indexes) that `ingest` does not, specify it. + +--- + +### FINDING 6.4 -- Requirement Conflict: Self-Describing vs Deterministic (MINOR) + +**Observation:** Constraint 2 says "self-describing -- must include enough metadata to be parsed without external schema knowledge." Constraint 4 says "deterministic serialization -- identical logical content must produce identical byte sequences." Self-describing formats (like JSON with type markers) inherently include metadata that can vary in representation (key order, whitespace, type marker encoding). Deterministic serialization requires stripping all such variation. + +**Resolution:** These are compatible if the canonical form includes the self-describing metadata in a deterministic way. Use CBOR with deterministic encoding (RFC 8949) which includes type tags (self-describing) in a canonical byte order (deterministic). Explicitly state that the self-describing metadata is part of the content that is deterministically serialized. + +--- + +## Summary by Severity + +| Severity | Count | Key Findings | +|----------|-------|-------------| +| CRITICAL | 5 | Nametag representation mismatch (1.1), Instance chain branching undefined (1.2), TXF migration path absent (2.1), Element taxonomy undefined (3.1), Pending transactions unaddressed (3.2), No integrity verification on reassembly (5.1) | +| MAJOR | 9 | GC algorithm undefined (1.3), Circular reference unhandled (1.4), IPFS model mismatch (2.2), Bundle size impact (2.3), TxfToken vs ITokenJson ambiguity (2.4), Deterministic serialization unspecified (3.3), Version overloading (3.4), Proof consolidation undefined (3.6), DAG node explosion (4.1), Streaming infeasible (4.2), Instance chain poisoning (5.2), Append-only contradiction (6.1) | +| MINOR | 5 | Content-addressing overhead (1.5), ZK aspirational (3.5), Instance chain index cost (4.3), SHA-256 sufficient (5.3), Flat vs DAG confusion (6.2), API inconsistency (6.3), Self-describing vs deterministic (6.4) | + +## Recommended Pre-Implementation Actions + +1. **Produce the element taxonomy** (addresses 3.1, 1.5, 4.1).

Is UXF a storage format (replacing TxfStorageData) or an exchange format (complementing it)? This drives half the design decisions. + +4. **Defer ZK proofs and proof consolidation** (addresses 3.5, 3.6). Test instance chains with mock alternative instances.

Problem Statement + +Two devices sharing one wallet identity (same secp256k1 master key, e.g. peer1 +CLI and peer2 daemon in `manual-test-full-recovery.sh`) publish pointers to the +**same aggregator slot** concurrently. Both write valid commitments under the +same signing identity, but the aggregator's read replica lag (30 – 60 s) +combined with the W7 walkback-floor rule (a wallet refuses to walk past a +version it has already confirmed as its own) produces a deadlock pattern: + +- Device A publishes `V=N`.

This unblocks the deterministic case, but in + practice with a 60 s read-replica window + 30 – 90 s poll cadence + 60 s + WALKBACK throttle, convergence is **statistical** and may never complete + inside a 4-minute test window.

Candidate Approaches + +### 2.1 Approach A — Aggregator-side compare-and-swap (CAS) + +**STATUS: RULED OUT (2026-05-24 owner directive). Section preserved for the record; see Update at top of RFC.** + +**Sketch.** Extend the aggregator's `submit_commitment` RPC with an optional +`expectedPriorVersion` field. The aggregator atomically rejects with a new +`VERSION_CONFLICT` status if the slot already holds a commitment at the +claimed version. The client retries with the aggregator-reported `currentVersion` +as its new baseline — single round trip, no walkback needed. + +**Pros:** +- Eliminates the read-replica race entirely (CAS is anchored at the aggregator's + authoritative view, not its replica). +- Designed to be backwards-compatible — existing clients omit the field and + behave as before; new clients gracefully fall back when the aggregator + returns `METHOD_NOT_FOUND` / ignores the field. **Subject to confirmation + by the `aggregator-go` team (Open Question 1).** +- **Asymptotic complexity unchanged** versus today's §8.5 analysis (both are + `O(k)` in the cohort). **The win is the per-conflict constant**: today each + publish attempt costs the full walkback + reconcile + throttle cycle + (~60 – 90 s); under CAS each conflict costs a single extra round trip + (~200 ms). For a 2-device cohort that is the difference between + ~minutes-to-converge and ~seconds-to-converge. + +**Cons:** +- Requires an aggregator-side schema change. Coordinated rollout with + `aggregator-go` (Go service) — touches the L3 layer, not just SDK-side. +- The "what is the current version of slot X" answer requires the aggregator to + maintain an auxiliary reverse index by `(wallet_signing_pubkey, slot)`. + **This is qualitatively different from "adding an optional field to an + RPC."** The aggregator's commitment store is keyed by `requestId` only; + the SMT stores blinded leaf values, so the new index cannot be derived + on-the-fly from existing storage. Introducing it requires the aggregator + to hold per-wallet signing-key metadata it currently never touches — + approaching a schema migration with new trust-surface exposure rather + than a pure protocol extension. + +**Effort.** Medium-high. Bilateral SDK + aggregator change with **server-side +data-model implications** (not just protocol-level). Needs a real +testcontainer-based integration test to exercise the conflict path. + +--- + +### 2.2 Approach B — Single-writer election via Nostr presence + +**STATUS: DROPPED in favor of Approach D (2026-05-24). Section preserved for the record; the silent-split-via-asymmetric-Nostr-reachability failure mode in Cons reproduces exactly the race this RFC tries to eliminate.** + +**Sketch.** Wallet processes that share an identity participate in a Nostr-based +"writer election." Only the elected writer publishes pointers; followers poll +the elected writer's published pointers and rebase locally. Election uses +Lamport clocks tiebroken on a presence-event signature; if the elected writer +goes silent for `T_failover`, the next-priority follower takes over. + +**Pros:** +- Pure SDK / transport-layer change. No aggregator dependency. +- Eliminates writer collisions at the source — the W7 floor never fires because + only one writer exists. +- Reuses existing Nostr transport — no new infrastructure. + +**Cons:** +- Requires a non-trivial election protocol (Lamport + tiebreak + failover + timeout). Network partitions degrade the guarantee — two writers can run + concurrently during a split. +- Convergence cost shifts to election latency (~10 s) per wallet boot. +- Followers' local writes (OUTBOX, finalization queue) still need to be + collected by the elected writer's flush — additional follower → writer + channel needed, or followers must publish their writes via OrbitDB OpLog + replication ONLY and rely on the writer's flush to anchor them. +- Failure modes are subtle: + - **Split-brain during failover** can produce two pointers at the same + version, replaying the same race we want to eliminate. + - **Silent split via asymmetric Nostr reachability.** Two devices share an + identity. The relay is fully operational. Device A reaches the relay + fine; device B reaches the relay fine; but B cannot observe A's presence + events (e.g., due to relay-side gossip-partition, NIP-29 group-membership + drift, or asymmetric NAT). B's Lamport+tiebreak election protocol cannot + detect A's prior election — B elects itself as writer while A is already + writing. Both write concurrently to the same aggregator slot, exactly + the failure mode this approach is meant to eliminate. Detection requires + a sentinel signal stronger than "absence of presence events," which adds + further protocol complexity. + +**Effort.** High. New protocol surface, new failure modes, careful test matrix +required. + +--- + +### 2.3 Approach C — Server-side anchoring + +**STATUS: RULED OUT. Hard variant requires the aggregator to hold per-wallet master keys (trust-model hard-no). Weak variant has no implementation merit per the Cons below — also fully blocked by the 2026-05-24 owner directive against any aggregator-side change. Section preserved for the record.** + +**Sketch.** The aggregator (or a sidecar service) listens for OpLog updates +via libp2p and anchors them itself, eliminating client-side pointer publishing +entirely. Clients only submit bundles; the server publishes pointers. + +**Pros:** +- Cleanest from the client's perspective — no race exists if there's only one + writer (the server). +- Server can batch anchors across wallets, amortising cost. + +**Cons:** +- The aggregator becomes a Profile dependency, blurring the layer boundary + established in `ARCHITECTURE.md`. Server availability becomes a wallet + availability dependency. +- Requires the server to hold per-wallet metadata (which slot owns which + OpLog stream) and to derive the per-version signing keys — which would + require it to hold the wallet's master key. **Hard no** for the current + trust model. +- A weaker variant — server witnesses the client's signed update and rebroadcasts + — sidesteps the key-custody issue but still requires the wallet to sign each + version, leaving us where we started for client-side races. Worse, the + server's rebroadcast is itself a write at an aggregator slot, so it inherits + the same `WALKBACK_FLOOR` problem one layer of indirection later. There is + no implementation merit to this variant even if the trust-model objection + to the strong variant were relaxed. + +**Effort.** Very high. Re-architects the trust boundary; would need a separate +spec. + +--- + +### 2.4 Approach D — Nostr win-broadcast (optimistic notify) + +**STATUS: SELECTED (2026-05-24). Phase 1 prototype landed in PR #257 (draft).** + +**Sketch.** After a successful `submit_commitment` for pointer `(walletId, v=N)`, the winning device immediately broadcasts an authenticated event over Nostr: + +``` +kind: 1 (NIP-01 short note; tag-discriminated) +tag: pointer-win: +content: JSON { _kind, v=1, version=N, cid, signingPubKey, ts, sig } +sig: secp256k1 over SHA-256(uint8 v ‖ uint32be version ‖ uint64be ts ‖ pubkey33 ‖ utf8 cid) +``` + +Same-identity siblings subscribe to `pointer-win:` and verify the payload signature against their own pointer signingPubKey (sibling = same key ⇒ trivial authentication). On valid receipt: dedupe `(signingPubKey, version)` via bounded LRU, trigger an early `recoverLatest()` + `reconcileLocalVersionDownward()` without waiting for the WALKBACK_FLOOR throttle to expire. + +**Pros.** +- **Pure client-side change.** Aggregator stays as one-time KV authenticated storage; satisfies owner directive. Approach A's server-side reverse-index complexity is not needed. +- **Strictly no-worse-than-today degradation.** Nostr broken / partitioned / sibling offline ⇒ falls back to existing WALKBACK_FLOOR + reconcileLocalVersionDownward cycle. The aggregator is still authoritative; Nostr is just a convergence-time hint. +- **Authentication trivial.** Siblings share the wallet's signing key by construction. Spoofing requires possession of the wallet key, in which case the attacker can already publish to the aggregator directly — no new attack surface. +- **Replay-bounded.** 5-minute `ts` window + dedup LRU bound replay attempts even on a hoarding relay. +- **Backward compatible.** Old clients don't subscribe to the tag; they fall back to the existing path. New clients ignore broadcasts they can't verify (different wallet, expired, malformed) and drop silently. + +**Cons.** +- **Phase 1 does not improve convergence — it is a measurement + wiring-infrastructure vehicle.** The subscriber's `recoverLatest() + reconcileLocalVersionDownward()` action mirrors the existing WALKBACK_FLOOR catch arm (PR #249) and: + - Does NOT clear the WALKBACK_FLOOR throttle (B still waits 60 s after a race-loss before its next publish attempt, regardless of broadcast). + - Does NOT call `fetchAndJoin(broadcast.cid)` (B's OpLog merge with A's contribution is still gated on OrbitDB replication). + - Returns no-op for the dominant same-version race (`reconcileLocalVersionDownward` requires `candidate < local`; in same-version race local == broadcast.version, so the check skips). + - May briefly help a narrow window where B's local was speculatively bumped to V=N and the replica still lags, by triggering the existing downgrade ~1 s earlier than the catch arm — but the throttle remaining armed neutralizes the gain. +- **Phase 2 is what actually solves convergence.** Adds an `adoptBroadcast(payload)` entrypoint on `ProfilePointerLayer` that: bypasses the `>=` comparison, advances local to `broadcast.version`, calls `fetchAndJoin(broadcast.cid)` to merge A's OpLog into B's local, and resets the WALKBACK_FLOOR throttle so the next publish can immediately target `broadcast.version + 1`. Phase 1's value is to validate the broadcast wire-format end-to-end and produce the fire/receive counts that decide whether Phase 2 is needed. +- **Lazy subscription install** (Phase 1). Receive-only devices that never publish themselves don't install their sibling subscription until their own first publish. *Phase 2* adds an eager polling loop or a `storage:pointer-ready` event from `ProfileStorageProvider`. +- **Nostr fanout cost.** Each successful publish ⇒ one signed event per relay subscribed. For a high-frequency wallet (multiple publishes per minute) this adds bandwidth. Bounded by the publish cadence the aggregator already enforces; not a new scaling concern. + +**Effort.** Small. Phase 1 (PR #257): 1 standalone crypto module (~233 LOC), 3 plumbing accessors, 1 event type, 1 lifecycle-manager hook, 1 Sphere subscriber + publisher. Phase 2 (conditional on Stage B.1 verdict): add `adoptBroadcast(payload)` entrypoint and eager-subscribe trigger. + +--- + +### 2.5 Approach E — Aggregator claim-lock (explicit lease via second requestId) + +**STATUS: ALTERNATIVE / NOT SELECTED. Kept as fallback if Approach D Phase 2 proves insufficient.** + +**Sketch.** Before publishing `requestId(walletId, N, "publish")`, write a tiny claim commitment to `requestId(walletId, N, "claim")`. The aggregator's existing one-shot KV semantics atomically pick a claim winner. The loser sees rejection on its own claim submit (~1 RTT) and switches to follower mode without ever attempting the publish. + +**Pros.** +- **Aggregator unchanged.** Same RPC, new requestId derivation; satisfies owner directive. +- **Deterministic per-conflict latency.** 1 extra aggregator round trip (~200 ms) instead of 60–90 s WALKBACK + reconcile + throttle cycle. *Bounded by network RTT, not by replica lag.* +- **Loser knows immediately.** Doesn't need a broadcast — the aggregator's rejection IS the signal. + +**Cons.** +- **Doubles aggregator submit load** per pointer publish (claim + publish). Operationally non-trivial if pointer publishes are frequent. +- **Stuck-claim failure mode.** Winner crashes between claim and publish ⇒ V=N slot is held but no V=N pointer exists. Other devices can't claim V=N (slot taken) and can't follow (no publish to fetch). Mitigation: encode a claim TTL via an `epoch` field in the requestId derivation (`requestId(walletId, N, "claim", epoch=t)`); after epoch expiry next epoch's claims are accepted. Requires aggregator clock-sync assumption (loose). +- **State machine more complex than Approach D.** Two new states: "won-claim-but-not-published-yet" (winner) and "lost-claim-waiting-for-winner's-publish" (loser). Both need timeouts + re-attempt logic. + +**Effort.** Medium. New requestId derivation, two new state-machine states, TTL/epoch handling. Smaller than Approach G; larger than D. + +--- + +### 2.6 Approach G — Per-device pointer slots (eliminate race at the source) + +**STATUS: LONG-TERM ARCHITECTURAL DIRECTION. Not for immediate implementation.** + +**Sketch.** Each device of the same wallet writes to a slot keyed by `(walletId, deviceId, N_device)` rather than `(walletId, N_wallet)`. No two devices ever race for the same slot. Readers enumerate all known device slots for a walletId, merge OpLogs across them (natural fit for OrbitDB's multi-writer CRDT model). + +**Pros.** +- **Zero conflicts.** Each device only competes with itself for its own monotonic slot. The §1 race vanishes at the source. +- **Aggregator unchanged.** New slot derivation; no new aggregator features needed. +- **Architecturally aligned.** Matches OrbitDB's native multi-writer OpLog model — possibly the "right" long-term shape for cross-device coordination, with the pointer layer just publishing per-device heads instead of trying to elect a global winner. + +**Cons.** +- **Large protocol revision.** Slot derivation change, reader logic change, device-list publication, stale-device pruning heuristic (devices that go offline for weeks). +- **Bootstrap problem.** New device must discover existing siblings before it can enumerate slots. Solvable via existing Nostr identity-binding events but adds boot-time latency. +- **Migration complexity.** Coexistence of old `(walletId, N)` slots with new `(walletId, deviceId, N_device)` slots during rollout window. Requires read-path fallback ordering. +- **Cardinality.** Aggregator state size grows linearly in device count × publish count rather than linearly in publish count. For wallets with many devices (rare but possible), this matters. + +**Effort.** Large. Slot derivation, reader logic, device discovery via Nostr, stale-device pruning, migration of existing wallets. Needs its own RFC (RFC-251-G). + +--- + +## 3. Recommendation + +**Pursue Approach D (Nostr win-broadcast).** Phased rollout: + +**Phase 1 — landed in PR #257 (draft). Scope: measurement + wiring. Does NOT improve race convergence; that lands in Phase 2.** +- Authenticated win-broadcast fires after every successful pointer publish. +- Sibling devices verify the signature against their own pointer signing pubkey, dedupe (signingPubKey, version) via bounded 256-entry LRU, then trigger `recoverLatest()` + `reconcileLocalVersionDownward()` — mirroring the existing WALKBACK_FLOOR catch arm (PR #249). This is a redundant trigger, not a convergence-accelerator: the throttle stays armed, `fetchAndJoin` is not called, and reconcile no-ops for same-version race. Phase 1's purpose is to validate the wire-format end-to-end and produce broadcast fire/receive counts in the debug log so Stage B.1 has measurement data. +- Crypto module fully unit-tested (24 tests). Lifecycle-manager emission contract tested (4 tests). Full unit suite: 8132 pass, 0 regressions. +- Gated as DRAFT until Stage B.1 verdict (5× `manual-test-full-recovery.sh` run after `unicitynetwork/ipfs-storage#7` deploys). + +**Phase 2 — conditional on Stage B.1 outcome:** +- Add `ProfilePointerLayer.adoptBroadcast(payload)` — direct entrypoint that bypasses `reconcileLocalVersionDownward`'s `>=` comparison so same-version races (the dominant remaining failure mode after Phase 1) get resolved. +- Add eager-subscribe trigger — `storage:pointer-ready` event from `ProfileStorageProvider` so receive-only devices install their sibling subscription before their own first publish. +- Decision criterion for proceeding to Phase 2: if Stage B.1 shows §C.2 still timing out OR WALKBACK_FLOOR > 5/run AND Phase 1 broadcast logs show ≥ 1 broadcast/conflict reaching siblings (signal Phase 1 is firing but not closing the gap), proceed to Phase 2. + +**Phase 3 — long-term architectural direction (separate RFC):** +- Move toward Approach G (per-device pointer slots). Eliminates the race at the source. Major protocol revision; needs its own RFC for slot derivation, device discovery, migration, stale-pruning. Phase 1 + Phase 2 don't preclude G — D and G compose (per-device slots remove the conflict, broadcasts continue serving as fast OpLog-head propagation). + +**Approach E (claim-lock) is held as fallback** if D Phase 1 + Phase 2 prove insufficient AND G is too large a project for the timeline. E's deterministic per-conflict latency is attractive, but the doubled aggregator load and stuck-claim TTL complexity make it second-choice to D + G. + +### Rationale for D over the alternatives + +| Criterion | D (Phase 1) | E (claim-lock) | G (per-device slots) | +|---|---|---|---| +| Aggregator change | None | None (new requestId derivation) | None (new requestId derivation) | +| Implementation effort | Small (landed) | Medium | Large (own RFC) | +| Per-conflict latency | ~1 s (Nostr RTT) | ~200 ms (1 extra agg RTT) | 0 (no race) | +| Strict same-version race | Phase 2 needed | Resolved | Resolved by construction | +| Degradation on transport failure | Falls back to today | Falls back to today | N/A — no race | +| Aggregator load delta | None | Doubled | Linear in device count | +| Operational risk | Low | Medium (stuck claims) | High during migration | + +**D is the smallest first step** that yields measurable progress on the convergence-time problem while leaving room for E (fallback) and G (long-term) as Stage B.1's empirical data informs the next decision. + +--- + +## 4. Acceptance Criteria (Approach D) + +### Phase 1 (PR #257 — landed, draft) + +1. **Crypto correctness.** Sign / verify roundtrip on real secp256k1 with canonical fixed-width hash; tamper rejection per field (`version`, `cid`, `ts`, `signingPubKey`, `sig`); schema-version rejection; replay-window enforcement (5-minute `ts` bound); anti-spoof guard at sign time. ✅ Covered by 24 unit tests in `tests/unit/pointer/win-broadcast.test.ts`. + +2. **Lifecycle-manager emission contract.** Successful pointer publish ⇒ emits `storage:pointer-published` event carrying signed payload + per-wallet broadcast tag. Transient/permanent publish failures DO NOT emit. Pointer layer without the `getSignerForWinBroadcast` accessor (legacy stub) gracefully skips with a log; publish-success contract preserved. ✅ Covered by 4 integration tests in `tests/unit/profile/lifecycle-manager-pointer-win-broadcast.test.ts`. + +3. **No regression on existing pointer paths.** `tests/unit/pointer/category-*.test.ts`, `tests/unit/profile/pointer/walkback-floor-retry.test.ts`, `tests/unit/profile/lifecycle-manager-reconcile-downward.test.ts`, `tests/unit/profile/lifecycle-manager-publish-retry.test.ts` pass unchanged. ✅ Full unit suite: 8132 pass, 0 regressions. + +4. **Operator observability.** New typed event `storage:pointer-published` declared in `StorageEventType` with explicit doc that it is *additive* to the existing `storage:replica-lag-reconciled` (does NOT replace — they fire from different code paths and signal different conditions). Phase 1 broadcast logs (debug-level `[Sphere] pointer-win broadcast {published|received}: ...`) provide the diagnostic surface for Stage B.1 measurement. + +5. **Degradation contract.** If `transport.publishBroadcast` is absent or rejects, the publish-success return is unaffected. If the Nostr subscription drops, missed broadcasts simply leave siblings on the existing WALKBACK_FLOOR + reconcile path. ✅ Verified by 4th integration test ("pointer without getSignerForWinBroadcast gracefully skips"). + +### Phase 2 (conditional) + +6. **`adoptBroadcast(payload)` entrypoint** on `ProfilePointerLayer` bypasses the `reconcileLocalVersionDownward`'s `>=` comparison and explicitly resets the WALKBACK_FLOOR throttle when called. Authentication: the payload's `signingPubKey` MUST equal this layer's own `signingPubKey` (caller has already verified the signature; this is a defense-in-depth check at the layer boundary). + +7. **Eager-subscribe trigger.** `ProfileStorageProvider` emits `storage:pointer-ready` once `getPointerLayer()` first returns non-null. Sphere subscribes and installs the per-wallet pointer-win subscription on receipt — fixes the Phase 1 lazy-install gap for receive-only devices. + +8. **Convergence under simulated replica lag.** A new integration test simulates two same-identity clients each publishing concurrently against an aggregator with 30 s of read-replica lag. Sibling adopts the winner's V=N within `2× Nostr RTT` (~2 s) of the first conflict — empirical proof that Phase 2 closes the convergence-time gap. + +### End-to-end (manual-test contract) + +9. **`manual-test-full-recovery.sh` §C.4 reaches §F on > 5 consecutive runs** with the IPFS sidecar from `unicitynetwork/ipfs-storage#7` deployed AND Approach D Phase 1 (+ Phase 2 if needed) active. WALKBACK_FLOOR count per run ≤ 5 (matches Approach A's original target). The first conflict per cycle still discovers the race naturally (no pre-emptive prediction); the broadcast just resolves it cheaply within ~1 s instead of re-entering the 60–90 s WALKBACK cycle. + +--- + +## 5. Out of Scope for This RFC + +- **Aggregator-side changes.** Out by owner directive — see Update at top of RFC. The aggregator stays as one-time KV authenticated storage; this RFC's protocol lives entirely above that layer. +- **Approach G's slot-derivation + migration spec.** The long-term per-device pointer slot architecture is in scope for `RFC-251-G` (a future RFC). This RFC's §2.6 only sketches G's shape and tradeoffs as a directional pointer. +- **Multi-writer fairness.** With > 2 devices the cohort still races, but each conflict is bounded by Nostr RTT (Phase 1) or `adoptBroadcast` (Phase 2). Backoff jitter or other fairness improvements can ride a follow-up PR if observed to matter. +- **Cross-device profile-level coordination.** Pointer-layer races are one symptom; OrbitDB OpLog merges across devices have their own race surface documented in `PROFILE-ARCHITECTURE.md §10.4`. That is a separate work stream — fixing pointer races here unblocks observability of those issues but does not solve them. +- **IPFS slow-pin amplification.** Tracked separately as `unicitynetwork/ipfs-storage#7` (the instant-pin sidecar). Stage B.1 — re-running the manual test 5× after the sidecar deploys — is the empirical measurement that decides whether D Phase 1 is sufficient or whether D Phase 2 also needs to land. + +--- + +## 6. Open Questions (Approach D) + +1. **Phase 2 trigger — Stage B.1 verdict.** What WALKBACK_FLOOR-per-run + §C.2-success-rate thresholds promote us from "Phase 1 sufficient" to "implement Phase 2 now"? Provisional threshold proposed in §3: §C.2 failing on any of 5 runs OR WALKBACK_FLOOR > 5/run AND Phase 1 broadcast logs show ≥ 1 broadcast/conflict reaching siblings (Phase 1 firing but not closing the gap). To be finalized after Stage B.1 data lands. + +2. **Same-version race — adopt-broadcast authentication boundary.** Phase 2 adds `ProfilePointerLayer.adoptBroadcast(payload)`. The Sphere subscriber has already verified the payload signature against own signing pubkey before calling. Does the layer redundantly re-verify (defense-in-depth, ~5 ms cost) or trust the caller (zero cost, smaller blast radius if a future caller forgets the verify step)? Provisional choice: redundant verify — pointer layer is a security boundary, the cost is negligible, and untrusted-caller scenarios become real if `adoptBroadcast` ever leaks beyond Sphere wiring. + +3. **Eager-subscribe — Phase 1 vs Phase 2 timing.** Phase 1's lazy-on-own-publish install is acceptable for *measurement* (Stage B.1's 2-device scenario where both devices publish). For PRODUCTION rollout, the receive-only case matters — wallets used only for receiving (cold-storage observers) never publish and would never install the subscription under Phase 1. Should Phase 2's `storage:pointer-ready` event ship sooner regardless of Stage B.1 verdict, just to fix the production gap? + +4. **Multi-device fanout cost.** A wallet with N active devices ⇒ each successful publish ⇒ N-1 broadcast deliveries. For N ≤ 3 (the realistic upper bound for personal wallets) this is negligible. If we ever support N > 10 (organizational wallets shared across many devices), the broadcast fanout becomes a real cost. Defer specific mitigation (relay-side TTL, broadcast batching, throttling) until N > 10 is observed. + +5. **Replay-window calibration.** Phase 1 uses 5-minute `ts` window. Too short ⇒ legitimate broadcasts dropped under clock skew between devices. Too long ⇒ replay attempts hoarded by malicious relays remain valid longer. 5 min is a reasonable starting bound (NTP-synced devices stay within seconds) but should be calibrated against observed clock skew distributions in production. Add a `pointer-win:replay-rejected` debug log to enable measurement. + +6. **Broadcast dedup LRU sizing.** Phase 1 uses 256 entries. Each entry is a `${signingPubKeyHex}:${version}` string (~80 bytes). 256 × 80 = ~20 KB memory — trivial. Sized to comfortably bound replay attempts within the 5-min `ts` window even for a hyperactive wallet publishing every second (300 unique versions/5 min ⇒ 256 entries covers the window). Validate during Stage B.1 — if observed broadcast rates are higher, bump. + +7. **Compatibility with future Approach G.** When per-device pointer slots (Approach G) eventually land, do per-device broadcasts continue using the same Nostr event kind and tag scheme, or do they need a parallel namespace to disambiguate per-wallet-aggregate vs per-device-slot broadcasts? Likely the latter (`pointer-win-device:` tag) to avoid receivers conflating the two. Defer the design until G is on the critical path. + +--- + +## 7. Decision Record + +### 2026-05-24 — Initial direction (Approach A, CAS) + +Drafted as design RFC recommending Approach A (aggregator-side compare-and-swap).

Pre-#6.a CAR sends did not pin the bundle locally; the default republish closure (Item #2 final closure, PR #189) downgrades to a CID-shape re-publish that the recipient cannot fetch.

For pre-#6.a `'car-over-nostr'` entries lacking a local pin, the recipient receives a CID it cannot fetch and surfaces the failure in its own bundle-acquirer logs — invisible to the sender.

The default closure now downgrades CAR-mode entries to a `'uxf-cid'` re-publish unconditionally because Item #6.a pins inline-CAR sends to the local IPFS node. Other transition-failed causes (OrbitDB read failure, unrelated SphereError, custom-installed closure throwing) remain. Retry on next verifier cycle (the entry's `checkedIds` flag was set so it won't be retried — wallet restart re-arms). | + +**Forward direction.** Once the "Re-publish from where?" architectural decision lands (using the IPFS-pinned CAR bytes referenced by `bundleCid`), the `'entry-tombstoned-or-missing'` skip reason will become rare — the verifier will materialize a fresh OUTBOX entry from the SENT record and CID, and re-publish from there. The historical `'transition-failed'` skips driven by the CAR-mode throw are already extinct under the default closure post-#6.a/#2-final; a custom-installed `republish` closure that retains the strict throw remains the only path back to that skip reason for new sends. + +--- + +### `transfer:off-record-spent` + +**Payload**: `{ tokenId, detectedAt, suspectedSiblingInstance, coinId, amount }` + +**What it means.** The `SpentStateRescanWorker` (Issue #174; UXF-TRANSFER-PROTOCOL §12.3.2) probed `oracle.isSpent(currentDestinationStateHash)` for a token in the local active pool (`status === 'confirmed'`) and the aggregator confirmed the state is SPENT. The local manifest still believed the token was spendable; the L3 chain says otherwise. + +The most common cause is **a sibling instance of the same wallet** — desktop + mobile sharing the same mnemonic / chain pubkey, primary + recovered backup, lost-then-found device. One instance spent the token without the other having pulled the spender's profile snapshot via §12.3.1 / Item #15 yet. The `suspectedSiblingInstance` flag is the worker's heuristic verdict on this: + +- **`true`** → neither the local OUTBOX nor the SENT ledger holds any record referencing `tokenId`, so the spend cannot have been initiated on THIS device. Almost certainly a sibling-device spend. +- **`false`** → either OUTBOX or SENT has a record. The local instance is (or was) the spender; the manifest just hasn't been GC'd to reflect the spend yet. Rare edge case — typically only happens if the SENT-write path raced the next rescan cycle. + +**Wallet-side state after the event.** Out of the box, the auto-installed default closure (`PaymentsModule.defaultSpentStateTransition`) does TWO things: +1. Calls `removeToken()` on the off-record-spent token — archive + tombstone + active-map deletion + persist. The token leaves the spendable pool; the tombstone prevents re-sync resurrection. +2. When a `DispositionWriter` is installed via `payments.installSpentStateAuditWriter()` (Sphere wires this from the wallet's `OrbitDbDispositionStorageAdapter` at bootstrap), ALSO writes a durable `_audit` record (reason `'off-record-spend'`, `auditStatus: 'audit-off-record-spend'`, §5.3 [E] / §5.4) for forensic traceability. + +If you've explicitly overridden the closure with a no-op via `setSpentStateRescanTransitionToAudit(...)`, the worker stays in detect-only mode — the event fires, but neither cleanup nor audit-record write happens. Legacy wallets without an `OrbitDbDispositionStorageAdapter` get the local cleanup but skip the durable `_audit` record (the writer slot stays null). + +**Diagnostic data to collect.** + +- The `tokenId`, `coinId`, `amount` from the payload (forensic triage). +- The `suspectedSiblingInstance` flag. +- The wallet's `getTokens({ tokenId })` output — has the disposition writer already transitioned the token to `_audit`? +- The aggregator's `oracle.isSpent()` answer — confirm the worker's call wasn't a transient false-positive. +- The wallet's sibling devices (if any) — check whether one of them recently sent this token (look at their `getHistory()`). +- Recent log lines matching `[Payments] SpentStateRescanWorker: …`. + +**Actions.** + +1. **Confirm the spend on a sibling device.** Ask the user whether another wallet instance recently spent this token. If yes → no action; the audit transition correctly reflects reality. +2. **No sibling device matches.** Inspect via direct profile read: + - Check OUTBOX (`getOutboxEntries()` or profile dump) for any entry with this `tokenId`. + - Check SENT (`getSentEntries()` or profile dump) similarly. + - Re-run `oracle.isSpent()` manually — does it still report `true`? +3. **If the aggregator now reports UNSPENT** (the worker raced a transient cache state): + - This is a false-positive transition. The token is in `_audit` but is actually spendable. Operator-override the disposition via the `_audit` → manifest promotion path (`dispositionWriter.promoteAuditEntry`) — escape hatch only after confirming the unspent status from multiple aggregator query attempts. +4. **If the aggregator confirms SPENT and no sibling can explain it:** the chain has a transition consuming our state that we did NOT author. This is either a key-compromise scenario (someone else holds the private key) or an aggregator-side bug. Escalate. Do NOT operator-override. + +**Forward direction.** + +- Repeated `transfer:off-record-spent` events firing for many `tokenId`s in a short window typically mean a sibling device recently sent multiple tokens. After the sibling's profile snapshot syncs (§12.3.1), the local view should converge naturally; the audit transitions are correct. +- If the event fires every cycle for the SAME `tokenId` (5 min cadence by default), the local Token.status flip path is NOT firing — either an explicit `setSpentStateRescanTransitionToAudit(...)` override is in place and not removing the token, OR `removeToken()` is throwing internally (check WARN-level `[Payments] defaultSpentStateTransition: removeToken failed` log lines). Out of the box the auto-installed default closure (`defaultSpentStateTransition`) calls `removeToken()` so the spent token is archived + tombstoned + dropped from the active map after the first detection. + +**Companion events.** Distinct from `transfer:double-spend-detected` (multi-device double-spend loss — fires from TWO trigger sources: (1) reactive submit-time when YOU attempt a send and the aggregator rejects with `STATE_ALREADY_SPENT_BY_OTHER`, Item #14 Phase 1; (2) JOIN-time when `loadFromStorageData` detects a snapshot loser whose `'transferring'` state was superseded by another device's winner, PR #182 / Item #14 Phase 2) and from `transfer:orphan-spending-detected` (covers `'transferring'` tokens stuck mid-send). All three can fire for related tokens during a sibling-device race; the `tokenId` is the join key. + +--- + +## Cross-cutting troubleshooting + +### "I see retention warnings for every SENT entry" + +Likely cause: the relay set's retention window is shorter than `verifyDelayMs`. Tune `NostrPersistenceVerifierOptions.verifyDelayMs` upward, or move to longer-retention relays. + +### "Orphan-spending detection fires after every restart" + +Likely cause: a send is genuinely stuck in `'transferring'` and the wallet hasn't been told whether to recover or escalate. Either enable `features.orphanAutoRecovery` (after confirming the safety contract) or manually triage via the steps in `transfer:orphan-spending-detected`. + +### "SENT-reconciliation-failed fires repeatedly for the same outboxId" + +Likely cause: persistent OrbitDB write failure at the SENT-ledger prefix. After `maxRetries`, auto-retry is suspended in-process. A wallet restart re-arms the worker. If failures persist across restarts, the underlying storage is broken — escalate. + +### "Tombstone GC reports zero purged but tombstones exist" + +Likely cause: the tombstones are within the retention window (default 30 days from their `deletedAt`). If you need to reclaim storage urgently, you can construct a worker with a shorter `retentionMs` — but DO NOT go below the longest realistic concurrent-replica pre-sync window.

Wallets that prefer the reactive-only surface (`transfer:double-spend-detected` at next `send()`) can explicitly set `features.spentStateRescan: false`. Deployments on restrictive relay sets that cannot absorb the verifier's steady load should set `features.nostrPersistenceVerifier: false`.

[Worked Examples](#10-worked-examples) + +--- + +## 1. Format Overview + +### 1.1 Purpose + +UXF (Universal eXchange Format) is a content-addressable packaging format for storing and exchanging pools of Unicity tokens across users, devices, and distributed storage systems. It provides: + +- **Deep deduplication** of shared cryptographic materials at every level of the token hierarchy (unicity certificates, SMT paths, nametag tokens). +- **Efficient extraction** of individual tokens at any historical state. +- **Incremental updates** -- adding, removing, or updating token records without rewriting the entire package. +- **Token integrity preservation** -- any extracted token is self-contained and verifiable without access to the full pool. +- **Content-addressable storage alignment** -- the internal DAG structure maps directly to IPFS/IPLD, enabling cross-user deduplication at the storage layer. + +### 1.2 Scope + +UXF operates at the **packaging layer** between individual token serialization (ITokenJson / CBOR v2.0) and transport/storage mechanisms. It is: + +- **Transport-agnostic** -- UXF packages are opaque byte sequences or JSON documents suitable for any transport (HTTP, NFC, Bluetooth, IPFS, file copy). +- **Encryption-agnostic** -- encryption may be layered on top but is not part of the format. +- **Platform-agnostic** -- the format is defined independently of any runtime (browser, Node.js, mobile). + +### 1.3 Design Goals + +| Goal | Description | +|------|-------------| +| **Backward compatibility** | Ingest and emit standard ITokenJson / CBOR v2.0 tokens without loss | +| **Self-describing** | Parseable without external schema knowledge (version fields, type markers) | +| **Streaming-friendly** | Begin extracting tokens before the entire package is downloaded | +| **Deterministic serialization** | Identical logical content produces identical byte sequences | +| **Size efficiency** | N tokens with shared materials significantly smaller than N independent serializations | +| **Representation/semantics separation** | Encoding may change freely; semantic meaning is fixed at creation | +| **Mixed-version tolerance** | Tokens may contain elements of heterogeneous semantic versions | +| **Reassembly completeness** | Reassembled tokens are indistinguishable from originals | + +### 1.4 Relationship to Existing Formats + +UXF builds upon and is interoperable with three existing serialization layers: + +**ITokenJson (state-transition-sdk v2.0):** The canonical self-contained token representation. A token in ITokenJson form carries its complete history: genesis data, ordered transactions with inclusion proofs, current state, and embedded nametag tokens. UXF ingests ITokenJson tokens via deconstruction and produces ITokenJson tokens via reassembly. The reassembled output is byte-for-byte semantically identical to the original. + +**TXF (sphere-sdk):** The wallet-level storage format. TXF wraps ITokenJson with wallet-specific metadata (`_integrity`, string-only nametag references, `previousStateHash`/`newStateHash` derived fields, outbox entries, tombstones). UXF replaces TXF's flat per-token storage model with a shared content-addressed DAG, but the TXF layer remains the interface between UXF and the wallet application. Wallet metadata (outbox, tombstones, mint entries) is stored in the package envelope, not in the element pool. + +**CBOR v2.0 (state-transition-sdk):** The binary wire format for individual token fields. UXF elements use CBOR as their binary encoding, following the same conventions as the existing SDK: CBOR tags for type identification (e.g., tag 1007 for UnicityCertificate), deterministic encoding (RFC 8949 Core Deterministic Encoding), and hex-encoded byte strings in the JSON alternate representation. + +### 1.5 Terminology + +| Term | Definition | +|------|------------| +| **Element** | A node in the content-addressed DAG. Each element has a type, a header, and typed fields. Some fields are child references (content hashes pointing to other elements). | +| **Element pool** | The flat, content-addressed store of all elements in a UXF package. Keyed by content hash. | +| **Content hash** | SHA-256 hash of an element's canonical CBOR encoding. Serves as the element's unique identifier and address in the pool. | +| **Child reference** | A field in a parent element whose value is the content hash of a child element, rather than inline data. | +| **Token manifest** | A mapping from `tokenId` to the content hash of the token's root element (TokenRoot). | +| **Instance chain** | A singly-linked list of semantically equivalent alternative representations of the same logical element, linked via `predecessor` hashes from newest to oldest. | +| **Deconstruction** | The process of recursively decomposing a self-contained token into elements and ingesting them into the pool. | +| **Reassembly** | The process of recursively resolving child references from a root element to produce a self-contained token. | +| **Representation version** | Encoding format version; may change when the element is re-serialized. | +| **Semantic version** | Protocol version governing validation rules; fixed at element creation and never changed. | + +--- + +## 2.

It is not stored directly on the TokenRoot to avoid redundancy. + +**Mutability:** Instance-chain-eligible. A TokenRoot may have alternative instances when the entire token history is replaced by a ZK proof (the ZK proof instance references the full-history instance as predecessor). + +**Mapping from ITokenJson:** +- `tokenId` -> `genesis.data.tokenId` (extracted to root for manifest indexing) +- `version` -> `version` field from ITokenJson (e.g., "2.0") +- `genesis` -> deconstructed GenesisTransaction sub-DAG +- `transactions` -> ordered array of deconstructed TransferTransaction sub-DAGs +- `state` -> deconstructed TokenState +- `nametags` -> each nametag token is recursively deconstructed into its own TokenRoot sub-DAG + +#### 2.2.2 GenesisTransaction (0x02) + +The mint (genesis) transaction that created the token.

There is no separate destination-state type. + +**State hash note:** The SDK-level state hash (used in authenticators, `previousStateHash`/`newStateHash`) is computed by the SDK over the predicate and data using the SDK's own algorithm. This is a protocol-level semantic value, distinct from the UXF content hash of the TokenState element. + +#### 2.2.7 Predicate (0x07) + +An ownership condition controlling who can authorize state transitions. + +| Field | Type | Required | Reference | Description | +|-------|------|----------|-----------|-------------| +| `header` | ElementHeader | yes | -- | Element header | +| `raw` | bytes | yes | leaf | The original CBOR-encoded predicate, preserved verbatim | + +**Design rationale:** Stored as opaque CBOR to preserve exact bytes for stable content hashes.

Content Hash Computation + +### 4.1 Hash Algorithm + +All content hashes use **SHA-256**, consistent with existing state-transition-sdk conventions. + +``` +content_hash = SHA-256(canonical_cbor_encoding(element)) +``` + +### 4.2 What Is Hashed + +The content hash covers the **complete canonical CBOR encoding** of the element, including: +- The element header +- All leaf data fields +- All child reference fields (as raw 32-byte hash values, NOT resolved content) + +The canonical form for hashing is a CBOR map with four keys: +``` +{ + "header": , + "type": , + "content": , + "children": +} +``` +This map-based form is used for ALL hash computations, regardless of whether the element is transmitted/stored using the positional array CBOR encoding (Section 6a). The positional array encoding and CBOR tags are wire format optimizations; they are NOT included in hash computation. + +The `type` field in the canonical hash form is the **integer type ID** (uint) from Section 2.1, NOT a string tag. Implementations using string-based type discriminators internally must map to the integer ID before hashing. + +The content hash does **not** include: +- The enclosing CBOR tag (identifies type in stream, not part of content) +- Package-level metadata (manifest entries, index entries) + +### 4.3 Child References in Hash Computation + +Child references are raw 32-byte SHA-256 values. A parent's content hash depends on children's hashes but NOT children's content. Replacing a child with a new instance (different hash) requires creating a new parent instance that references the new child hash. + +### 4.4 Deterministic CBOR Encoding Rules + +UXF mandates **RFC 8949 Section 4.2.1 Core Deterministic Encoding**: + +1. Integers: shortest encoding. +2. Maps: keys sorted by encoded byte comparison. +3. No indefinite-length encoding. +4. Preferred floating-point: shortest preserving value. +5. No duplicate map keys. +6. Byte/text strings: definite-length, shortest prefix. + +Additional UXF rules: + +7. Array fields: order per element type definition. Header always first. +8. Null encoding: absent optional fields encoded as CBOR null (0xF6), NOT omitted. +9. Empty arrays: encoded as `[]` (0x80), NOT omitted. +10. Hash canonical form: the input to SHA-256 is always the deterministic CBOR encoding of the 4-key map form `{header, type, content, children}`, NOT the tagged positional array form used in wire encoding. + +### 4.5 CDDL Types + +```cddl +content-hash = bstr .size 32 +child-ref = content-hash +nullable-child-ref = content-hash / null +``` + +--- + +## 5.

Users maintain pools of tokens representing diverse asset types (fungible coins, NFTs, nametags) where: + +- A single asset class (e.g., BTC, ETH, UCT) may be spread across multiple tokens. +- A single token may carry multiple asset classes simultaneously. +- Tokens exchanged between users must be serialized, transmitted, and imported as complete verifiable units. + +The existing SDK serialization (`ITokenJson`, CBOR) handles individual token round-trips but lacks a **multi-token pool-level packaging format** that: + +1. **Deduplicates shared cryptographic materials** (e.g., inclusion proofs referencing the same aggregator round, shared unicity certificates, common nametag tokens embedded in multiple tokens). +2. **Supports efficient extraction** of a single token at its latest locally-known state or at any historical state. +3. **Enables incremental updates** — adding, removing, or updating individual token records without rewriting the entire package. +4. **Preserves token integrity** — the format must allow verification of any extracted token without access to the full pool. +5. **Aligns with content-addressable storage** (IPFS/IPLD) — structuring data so that shared sub-trees between users and tokens naturally deduplicate at the storage layer. + +--- + +## Token Structure Model + +### Tokens as Append-Only Structures + +A token is an ever-growing, append-only data structure. Once an element (e.g., a transaction, genesis record) is added to a token, it cannot be modified or removed — the token's integrity depends on the immutability of its historical chain. The sole exception is **unicity proofs**, which may have alternative representations added via instance chains (see Versioning Model) (e.g., replaced with a more compact or more recent proof) because their semantics — proving that a specific state transition was committed exactly once — remain invariant regardless of the proof's representation. + +**Invariant:** The semantics of any element, once committed to a token, must never change. Representation (encoding, field ordering, compression) may evolve across versions, but the logical meaning of the element must be preserved exactly. + +### Hierarchical Structure and Content-Addressed DAG + +A token is a deeply hierarchical data structure — its JSON/CBOR form is a tree, not a flat record. For example: + +``` +Token +├── genesis +│ ├── transactionData (tokenId, tokenType, coinData, salt, recipient, ...) +│ ├── inclusionProof +│ │ ├── merkleTreePath (array of SMT nodes) +│ │ ├── authenticator (pubkey, signature, stateHash) +│ │ └── unicityCertificate +│ │ ├── inputRecord (roundNumber, epoch, hash, ...) +│ │ ├── shardTreeCertificate +│ │ ├── unicityTreeCertificate +│ │ └── unicitySeal (BFT signatures) +│ └── destinationState (predicate, data) +├── transactions[] +│ └── (each has the same deep structure as genesis) +├── state (current predicate + data) +└── nametags[] (each is itself a full Token — recursive) +``` + +This hierarchy maps naturally to a **content-addressed DAG** (as in IPFS/IPLD): every node in the tree — at any depth — is independently content-hashed and addressable. A "subelement" of one token (e.g., a unicity certificate buried inside a transaction's inclusion proof) can be the exact same DAG node referenced by a completely different token's transaction. Sharing is not limited to top-level elements; it occurs at every level of the tree. + +### Storage Model: Deconstruction and Reassembly + +A UXF bundle does **not** store tokens as monolithic objects. Instead, each token is **recursively deconstructed** into its constituent elements — and those elements into their subelements, and so on down the full depth of the hierarchy — upon ingestion. Every node in the resulting DAG is content-hashed and stored exactly once in a shared, flat **element pool**. Parent elements reference their children by content hash rather than embedding them inline. + +This recursive deconstruction is what enables deep deduplication: sharing happens at every level of the tree, not just at the top. For instance: + +- Two tokens transacted in the same aggregator round share the same **unicity certificate** node (a sub-sub-element of their respective inclusion proofs). +- A nametag token embedded inside token A's transaction may itself be a full token that also appears independently in the bundle — it is stored once and referenced from both locations. +- Two inclusion proofs from the same round share upper **SMT path segments** as common subtree nodes. +- An element from one token may contain (reference) subelements that belong to a different token — this is natural and expected in the DAG model. + +The bundle maintains a **token manifest** — a lightweight index that maps each `tokenId` to the content hash of its root element. From that root, the full token tree can be traversed by following child references through the element pool. The manifest contains no element data, only root references. + +``` +UXF Bundle +├── Package Envelope (version, metadata) +├── Element Pool (shared, content-addressed DAG nodes) +│ ├── node[hash_A] — unicity certificate (shared by 5 inclusion proofs across 3 tokens) +│ ├── node[hash_B] — authenticator (subelement of an inclusion proof) +│ ├── node[hash_C] — inclusion proof → references [hash_A, hash_B, hash_D] +│ ├── node[hash_D] — SMT path segment (shared by 2 inclusion proofs) +│ ├── node[hash_E] — transaction → references [hash_C, hash_F, ...] +│ ├── node[hash_F] — destination state (predicate + data) +│ ├── node[hash_G] — genesis → references [hash_H, hash_I, ...] +│ ├── node[hash_J] — nametag token root (itself a full token DAG, shared by 12 transactions) +│ └── ... +├── Token Manifest +│ ├── token_id_1 → hash_root_1 (root of token 1's DAG) +│ ├── token_id_2 → hash_root_2 (root of token 2's DAG; subtrees overlap with token 1) +│ └── ... +└── Indexes (by tokenType, by state hash, etc.) +``` + +**Reassembly** is the process of starting from a token's root hash in the manifest, recursively resolving all child references through the element pool, and recomposing the full hierarchical structure into a self-contained token (e.g., `ITokenJson` / CBOR v2.0). The reassembled token is indistinguishable from the original — it passes the same validation and can be exported for exchange via existing SDK mechanisms. + +For **historical state reassembly**, the token's root node references an ordered list of transaction sub-DAGs; reassembling at state N means traversing only the genesis sub-DAG plus the first N transaction sub-DAGs and their transitive children. + +**Deconstruction** is the reverse: a self-contained token tree is recursively walked, each node is content-hashed, and only nodes not already present in the pool are added. Since the pool is content-addressed, ingesting a token that shares sub-trees with already-stored tokens adds only the novel nodes. + +### Element Composition and Cross-Token References + +Each node in the element pool is a self-contained unit with its own version, type, and content hash. A node references its children by their content hashes — never by embedding them inline. Inline embedding only occurs at **reassembly** time, when a self-contained token is recomposed for export. + +Because the pool is a flat content-addressed store, the parent-child relationship is not confined to a single token's tree. A node that is a subelement of one token may equally be a subelement of another: + +- A **unicity certificate** (deep inside token A's transaction → inclusion proof → certificate) may be the same DAG node referenced by token B's transaction → inclusion proof → certificate. +- A **nametag token** referenced by a transaction's `dest_ref` is itself a complete token sub-DAG. If that same nametag token exists independently in the bundle, it is the same set of nodes — no duplication. +- An **SMT path segment** shared by two inclusion proofs (from different tokens, same aggregator round) is stored once and referenced twice. + +This means the element pool is a **shared DAG**, not a collection of independent per-token trees. Token boundaries are defined by the manifest (which root hash belongs to which `tokenId`), not by the DAG structure itself. + +### Versioning Model + +Every token and every element within a token carries a **version** that governs both its **representation** (serialization format, field layout, encoding) and its **semantics** (the logical meaning and processing rules). + +#### Version Dimensions + +| Dimension | What it controls | When it changes | Compatibility rule | +|---|---|---|---| +| **Representation version** | Binary/JSON encoding, field names, field order, optional field presence | When the serialization format evolves (e.g., new CBOR layout, field renaming) | Parsers must support reading all known representation versions and normalizing to the latest internal form | +| **Semantic version** | Processing rules, validation logic, hash computation, cryptographic algorithms | When the protocol itself evolves (e.g., new signing algorithm, new proof structure) | Semantic changes must be backward-compatible at the element level: a v1 transaction retains v1 validation rules forever, even inside a v2 token | + +#### Version Granularity + +- **Token-level version** — declares the overall token format version (e.g., `"2.0"`). Determines the envelope structure and which element versions are expected. +- **Element-level version** — each element (genesis, transaction, inclusion proof, predicate, authenticator) carries its own version. This enables **mixed-version tokens**: a token minted under v1 semantics can accumulate v2 transactions as it evolves through state transitions. + +#### Mixed-Version Evolution + +A token's lifecycle may span multiple protocol versions: + +``` +Token (v2.0 envelope) +├── genesis (v1 semantics, v1 representation) +├── transaction[0] (v1 semantics, v1 representation) +├── transaction[1] (v1 semantics, v2 representation) ← re-serialized, same meaning +├── transaction[2] (v2 semantics, v2 representation) ← new protocol rules +└── state (v2 semantics) +``` + +This means: +- A parser encountering an element must inspect its version to select the correct deserialization and validation logic. +- An element's semantic version is fixed at creation and never changes (append-only invariant). +- An element's representation version may change (e.g., when the package is re-serialized into a newer format), provided the semantics are preserved exactly. +- The token-level version reflects the highest semantic version present, or the version of the envelope format, not necessarily the version of every element within. + +#### Element Instance Chains + +An element in the pool may have multiple **instances** — alternative representations of the same logical element that are all semantically equivalent (they prove or assert the same thing). An updated instance is stored as a **separate DAG node that references its predecessor**, forming a singly-linked **instance chain** (newest to oldest, analogous to a blockchain). The previous instance is never removed — content-addressability and existing references are preserved. + +Instance chains serve three distinct purposes, all using the same chaining mechanism: + +**1. Representation evolution** — an element is re-serialized into a newer encoding format (e.g., CBOR v2 layout) without changing its version number or semantics: + +``` +element[hash_v2] (repr=2, sem=1) → predecessor: hash_v1 +element[hash_v1] (repr=1, sem=1) → predecessor: null (original) +``` + +**2. Proof consolidation** — multiple individual unicity proofs are merged into a single subtree of the aggregator's Sparse Merkle Tree, dramatically reducing space. The consolidated proof is semantically equivalent (it still proves the same set of state transitions were committed exactly once) but structurally different: + +``` +consolidatedProof[hash_C] (proves transitions 0..4 via shared SMT subtree) + → predecessor: hash_P4 +individualProof[hash_P4] (transition 4) → predecessor: hash_P3 +individualProof[hash_P3] (transition 3) → predecessor: hash_P2 +individualProof[hash_P2] (transition 2) → predecessor: hash_P1 +individualProof[hash_P1] (transition 1) → predecessor: null +``` + +Here the consolidated proof replaces a chain of individual proofs with a single compact element. Both forms are valid — the consumer can choose either during reassembly. + +**3. ZK proof substitution** — a full transaction history (genesis + N transitions with all their subelements) is replaced by a compact zero-knowledge proof that attests to the correctness of the entire state transition chain. The ZK proof is semantically equivalent to the full history — it proves the same thing — but is orders of magnitude smaller: + +``` +zkProof[hash_ZK] (proves valid chain from genesis to state N) + → predecessor: hash_HISTORY_ROOT +historyRoot[hash_HISTORY_ROOT] (full: genesis + transitions[0..N]) + → predecessor: null +``` + +The full history and the ZK proof are **alternative instances** of the same logical element (the token's provenance). During reassembly, the consumer selects which to include: +- **ZK proof** — for compact transfer payloads where the recipient trusts ZK verification. +- **Full history** — for recipients who require the complete auditable chain, or for archival purposes. + +#### Instance Selection During Reassembly + +During reassembly, each element reference in the DAG is resolved through the instance chain. The consumer provides an **instance selection strategy** that governs which alternative to use: + +| Strategy | Behavior | Use case | +|---|---|---| +| **latest** (default) | Use the head of the chain (most recent instance) | General use — picks the most compact/optimized form | +| **original** | Walk to the tail of the chain (first instance) | Archival, debugging, or when the original encoding is required | +| **by representation version** | Select the instance matching a specific `repr` version | Compatibility with older SDK versions | +| **by kind** | Select by instance kind (e.g., `full-history` vs. `zk-proof` vs. `consolidated-proof`) | When the consumer needs a specific proof form | +| **custom predicate** | Caller-supplied function evaluating each instance | Advanced use cases | + +Multiple strategies can be composed: e.g., "prefer ZK proof, fall back to consolidated proof, fall back to full history." + +A reassembled token is always valid regardless of which instance is selected — all instances in a chain are semantically equivalent. The choice affects only size, verification method, and level of detail. + +``` +UXF Bundle — Element Pool (with instance chains) + +consolidatedProof[hash_CP] → predecessor: hash_P2 + (compact SMT subtree covering 2 proofs) +individualProof[hash_P2] → predecessor: hash_P1 +individualProof[hash_P1] → predecessor: null + +zkProof[hash_ZK] → predecessor: hash_HR + (attests to full genesis→stateN chain) +historyRoot[hash_HR] → predecessor: null + (full transaction history sub-DAG) + +transaction[hash_T1] → references proof: hash_P1 (original reference) + ↳ reassembly with strategy=latest resolves to hash_CP + ↳ reassembly with strategy=original resolves to hash_P1 + +tokenRoot[hash_R1] → references history: hash_HR (original reference) + ↳ reassembly with strategy={kind: zk-proof} resolves to hash_ZK + ↳ reassembly with strategy=original resolves to hash_HR +``` + +**Instance chain index**: the bundle maintains a lightweight index mapping each element hash to the head of its instance chain, enabling O(1) lookup of the latest instance without walking the chain. The index also records the **kind** of each instance for efficient kind-based selection. + +#### Element Header Encoding + +Each element includes a header as the first item in its serialized form, encoding its version, lineage, and kind: + +``` +header = { + representation: , — encoding format version + semantics: , — protocol semantic version (fixed at creation) + kind: , — instance kind (e.g., "individual-proof", "consolidated-proof", + "zk-proof", "full-history", "default") + predecessor: — content hash of the previous instance, or null for the original +} +``` + +Or as a compact tuple `[repr_version, sem_version, kind, predecessor_hash]` in CBOR. The `predecessor` field is `null` for the original instance and contains the content hash of the previous instance for all subsequent entries in the chain. The `kind` field enables efficient instance selection during reassembly without inspecting element contents. The representation version is local to the encoding; the semantic version is protocol-global and monotonically increasing. + +--- + +## Scope + +### In Scope + +1. **Format specification** — a formal schema for the UXF package structure, covering: + - Package envelope (version, metadata, content manifest). + - **Element pool** — the shared, content-addressed DAG store; every node (at any depth of the token hierarchy) is stored once and addressed by content hash; insertion, lookup, garbage collection, and version chain management semantics. + - **Token manifest** — maps each `tokenId` to the content hash of its root DAG node; the full token tree is recoverable by recursively traversing child references from the root. + - Token record layout (referencing existing `ITokenJson` / CBOR v2.0 structures from `@unicitylabs/state-transition-sdk`; defines the reassembled output format). + - **Versioning and instance chains** — token-level and element-level version fields encoding representation version, semantic version, instance kind, and predecessor reference; element instance chains (newer instances referencing their predecessors); instance chain index; rules for mixed-version token construction, validation, and instance selection during reassembly (by kind, by version, by strategy). + - **Element taxonomy** — formal definition of each element type (genesis, transaction, inclusion proof, predicate, authenticator, nametag reference, unicity certificate), its subelement structure, and its reference/inline embedding rules. + - **Mutability rules** — all elements are immutable once stored; "updates" are expressed as new instances appended to the instance chain (never in-place mutation). Rules governing which element types may have alternative instances (e.g., proofs may be consolidated, transaction histories may be replaced by ZK proofs) vs. which are strictly single-instance (e.g., individual transaction data). + - Deduplication scheme for shared materials (unicity certificates, SMT path segments, nametag tokens, predicates). + - Indexing structures for O(1) token lookup by `tokenId`, by `tokenType`, by state hash, and by transaction history position. + - Incremental update protocol (append, remove, update operations on the package). + - Integrity metadata (per-token and package-level content hashes). + +2. **IPFS/IPLD alignment** — the UXF element pool is inherently a content-addressed DAG, making the mapping to IPFS/IPLD natural and direct: + - Define how each DAG node (element) maps to an IPLD block with CID-based links to children. + - Chunking strategy for large token pools (manifest partitioning, element pool sharding). + - Cross-user deduplication: when two users' bundles share sub-DAGs (e.g., tokens with common history or shared nametags), IPFS automatically deduplicates at the block level because identical content produces identical CIDs. + - IPNS integration points for mutable package roots (the manifest root CID changes as tokens are added; IPNS provides a stable name for the latest version). + +3. **Deconstruction and reassembly operations** — specify and implement: + - **Deconstruct** a self-contained token (`ITokenJson` / CBOR) into elements and ingest into the pool, deduplicating against existing elements. + - **Reassemble** a token at its latest locally-known state from the element pool — the result is a self-contained, verifiable `ITokenJson` indistinguishable from the original. + - **Reassemble at historical state N** — collect genesis + first N transaction elements and their associated proofs; produce a valid self-contained token reflecting that historical state. + - Extract subset of tokens by filter (token type, coin class, value threshold). + - Extract minimal transfer payload (token + pending transaction, as per existing `exportFlow` semantics). + +4. **Reference implementation** — TypeScript library providing: + - `UxfPackage` class: create, open, read, write UXF bundles. Encapsulates the element pool, token manifest, and indexes. + - `ingest(pkg: UxfPackage, token: Token) -> void`: deconstruct a self-contained token into elements, deduplicate against the pool, and add/update its manifest entry. + - `ingestAll(pkg: UxfPackage, tokens: Token[]) -> void`: batch deconstruction of multiple tokens. + - `assemble(pkg: UxfPackage, tokenId: TokenId) -> Token`: reassemble a token at its latest locally-known state from the element pool. The result is a self-contained, verifiable token. + - `assembleAtState(pkg: UxfPackage, tokenId: TokenId, stateIndex: number) -> Token`: reassemble at a specific historical state (genesis + first N transitions). + - `removeToken(pkg: UxfPackage, tokenId: TokenId) -> UxfPackage`: remove a token from the manifest (elements are not garbage-collected automatically). + - `merge(a: UxfPackage, b: UxfPackage) -> UxfPackage`: combine two packages with deduplication. + - `diff(a: UxfPackage, b: UxfPackage) -> UxfDelta`: compute minimal delta between package versions. + - `verify(pkg: UxfPackage) -> VerificationResult`: validate package and token integrity. + - `addInstance(pkg: UxfPackage, originalHash: Hash, newInstance: Element) -> void`: append a new instance (consolidated proof, ZK proof, re-encoded element) to an element's instance chain; the new instance references the previous head as its predecessor. + - `consolidateProofs(pkg: UxfPackage, tokenId: TokenId, txRange: [number, number]) -> void`: merge a range of individual unicity proofs into a consolidated SMT subtree instance. + - `assemble` / `assembleAtState` accept an optional **instance selection strategy** (latest, original, by-kind, by-representation-version, or custom predicate) to control which instance from each element's chain is used during reassembly. + - Version-aware serialization: read any known representation version, write the latest. + - CBOR and JSON serialization for all structures. + - IPLD-compatible DAG export. + +### Out of Scope + +- Aggregator protocol changes or on-chain modifications. +- Transport-layer concerns (NFC, Bluetooth, HTTP — UXF is transport-agnostic). +- Wallet UI or application-level token management logic. +- Encryption or access control on the package contents (may be layered on top separately). + +--- + +## Existing Structures to Build Upon + +### Base SDK (`@unicitylabs/state-transition-sdk` v2.0) + +| Structure | Role | Serialization | +|---|---|---| +| `Token` (`ITokenJson`) | Self-contained token with full history | JSON (hex strings) + CBOR | +| `TokenId` | 32-byte unique token identifier | 64-char hex / CBOR bytes | +| `TokenType` | 32-byte asset class identifier | 64-char hex / CBOR bytes | +| `TokenState` | Current ownership predicate + optional data | JSON object / CBOR array | +| `MintTransactionData` | Genesis parameters (immutable) | JSON object / CBOR array | +| `TransferTransactionData` | Per-transfer parameters | JSON object / CBOR array | +| `InclusionProof` | SMT path + authenticator + unicity certificate | JSON object / CBOR array | +| `UnicityCertificate` | BFT-signed aggregator round commitment | Hex-encoded CBOR (tag 1007) | +| `Authenticator` | Public key + signature + state hash | JSON object / CBOR array | +| `RequestId` | SHA-256(pubkey \|\| stateHash) — SMT leaf address | DataHash imprint | + +### Sphere SDK (existing TXF layer) + +| Structure | Role | Notes | +|---|---|---| +| `TxfStorageData` | Wallet-level token pool container | Keyed by `_`, includes metadata, tombstones, outbox | +| `TxfToken` | Simplified token representation | Adds `_integrity`, string-only nametags | +| `TxfTransaction` | Transfer with `previousStateHash` / `newStateHash` | Derived fields for quick lookups | +| `TxfMeta` | Package metadata (version, address, IPNS name, device ID) | Wallet-specific, needs generalization | + +### Key Deduplication Targets + +1. **Unicity certificates** — tokens transacted in the same aggregator round share the same certificate. Certificates are ~500-2000 bytes each and dominate proof size. +2. **Nametag tokens** — embedded recursively in `ITokenJson.nametags[]`; the same nametag token may appear in dozens of other tokens. +3. **SMT path prefixes** — inclusion proofs for tokens in the same round share upper path segments in the sparse Merkle tree. +4. **Predicate parameters** — tokens owned by the same user share `tokenType`, `signingAlgorithm`, `hashAlgorithm` fields (though `nonce` and `publicKey` differ per state). + +--- + +## Design Constraints + +1. **Backward compatibility** — UXF must be able to ingest and emit standard `ITokenJson` / CBOR v2.0 tokens without loss. +2. **Self-describing** — the format must include enough metadata to be parsed without external schema knowledge (version field, content type markers). +3. **Streaming-friendly** — it should be possible to begin extracting tokens before the entire package is downloaded. +4. **Deterministic serialization** — identical logical content must produce identical byte sequences (required for content-addressable storage). +5. **Size efficiency** — a UXF package of N tokens with shared materials should be significantly smaller than N independent `ITokenJson` serializations. +6. **Representation/semantics separation** — representation (encoding) may change freely across versions; semantics (meaning, validation rules, hash computation) of an element are fixed at the element's creation and must never be altered. A v1 element re-serialized into v2 representation must validate identically under v1 semantic rules. +7. **Mixed-version tolerance** — parsers and validators must handle tokens containing elements of heterogeneous semantic versions. Validation dispatches to the correct semantic version handler per element, not per token. +8. **Reassembly completeness** — a token reassembled from the element pool must be fully self-contained and indistinguishable from the original. It must pass the same validation, produce the same state hashes, and be directly usable by existing SDK import/export mechanisms without any knowledge of UXF. + +--- + +## Acceptance Criteria + +1. A formal specification document defining the UXF binary and JSON formats with field-level descriptions, CDDL or JSON Schema definitions, and worked examples. +2. A TypeScript reference implementation passing unit tests for all operations listed in scope. +3. Deduplication benchmarks showing measured size reduction on realistic token pools (10, 100, 1000 tokens with varying overlap). +4. Round-trip tests: `assemble(ingest(token))` produces a token identical to the original for all supported token configurations (fungible, NFT, nametag, multi-coin, with and without pending transactions). Deconstructing the same token twice does not duplicate elements in the pool. +5. IPLD DAG export produces valid CIDs and the structure is navigable via standard IPFS tooling. +6. Historical state extraction is verified: extracting a token at state N and replaying from genesis yields the same state hash as the Nth transition's destination. +7. Mixed-version round-trip: a token with v1 genesis + v2 transactions is packed, unpacked, and validated correctly — each element applying its own semantic version's rules. +8. Proof update test: replacing a unicity proof via `updateProof` preserves token validity; attempting to modify any other element type is rejected. +9. Re-serialization test: re-encoding a v1-representation element into v2 representation produces a byte-different but semantically identical element that passes validation under v1 semantic rules. +10. Cross-token DAG sharing: ingesting two tokens that share a sub-DAG (e.g., same unicity certificate, same nametag token) results in a single copy of the shared nodes in the pool; both tokens reassemble correctly from the shared structure. +11. Instance chain test: after adding an alternative instance (e.g., consolidated proof, re-encoded element), the old instance remains in the pool; the chain is walkable from head to original; reassembly with `strategy=latest` uses the head; `strategy=original` uses the tail; `strategy={kind: X}` selects by kind. +12. Proof consolidation test: merging N individual proofs into a consolidated SMT subtree instance produces a valid, smaller element; reassembly with the consolidated instance produces a token that passes verification; reassembly with `strategy=original` still produces the token with individual proofs. +13. ZK proof substitution test: replacing a full transaction history with a ZK proof instance produces a valid reassembled token under ZK verification; reassembly with `strategy={kind: full-history}` returns the complete auditable chain; both forms are semantically equivalent. diff --git a/docs/uxf/TEST-FIXTURES-SPEC.md b/docs/uxf/TEST-FIXTURES-SPEC.md new file mode 100644 index 00000000..314d59fc --- /dev/null +++ b/docs/uxf/TEST-FIXTURES-SPEC.md @@ -0,0 +1,1034 @@ +# UXF Test Fixtures Specification + +**Status:** Ready for implementation +**Date:** 2026-03-26 + +This document defines mock token data for testing UXF deconstruction (`deconstructToken`) and reassembly (`assembleToken`) round-trips.

+> where `token.coins` is the post-prune list (zero-amount entries normalized to `[]` at ingest). Coin tokens (non-empty coinData) and NFT tokens (empty coinData) are class-disjoint at the protocol level — no token carries both. Coin tokens may be split via `TokenSplitBuilder` (each output gets a fresh `tokenId`); NFT tokens are transferred whole-token only (preserving `tokenId`). +> +> **Token identity invariance**: `token.id` derives from `genesis.data.tokenId` and is IMMUTABLE across proof attachment. Attaching an inclusion proof changes the token's *CBOR serialization* (and therefore its CID) but never `token.id`. The `_invalid` and `_audit` collections key by `(tokenId, observedTokenContentHash)` to disambiguate multiple representations of the same `tokenId`. + +## 1. Token Field-by-Field Decomposition + +The canonical token JSON structure (ITokenJson / TXF v2.0) has five top-level fields. What follows is a field-by-field analysis based on the actual SDK source and sphere-sdk usage patterns. + +### 1.1 `token.version` + +- **Value:** String `"2.0"` (currently the only production version) +- **Byte size:** 3 bytes as UTF-8; in JSON with key: ~18 bytes (`"version":"2.0"`) +- **Shared across tokens in same wallet:** Yes, always identical +- **Shared across wallets:** Yes, always identical (single protocol version) +- **Mutable:** No, fixed at token creation +- **UXF recommendation:** Inline. Too small to warrant a separate DAG element. Include in the token root element header. + +### 1.2 `token.state` (TokenState) + +```typescript +{ + data: string, // Hex-encoded state data or null + predicate: string // Hex-encoded CBOR predicate +} +``` + +- **Byte size:** The predicate is a CBOR-encoded `UnmaskedPredicate` containing: + - `tokenId` (32 bytes) + - `tokenType` (32 bytes) + - `signingAlgorithm` identifier + - `hashAlgorithm` identifier (SHA256) + - `publicKey` (33 bytes compressed secp256k1) + - `salt` (32 bytes) + - Total CBOR: approximately **150-200 bytes** hex-encoded as ~300-400 characters +- **`data` field:** Usually `null` or empty string for fungible tokens; variable for NFTs +- **Total typical size:** 400-500 bytes JSON +- **Shared across tokens in same wallet:** Partially. The `publicKey`, `signingAlgorithm`, `hashAlgorithm` fields repeat. But `tokenId`, `tokenType`, and `salt` differ per token, making the full predicate unique per token state. +- **Shared across wallets:** No. Different keys mean different predicates. +- **Mutable:** Yes, this is the CURRENT state. It changes on every transfer (new owner's predicate replaces it). +- **UXF recommendation:** Separate DAG element. The state is mutable (replaced on transfer) and unique per token, but its sub-components (predicate engine/algorithm identifiers) could be shared. However, the predicate as a whole is small enough that splitting it further adds complexity without meaningful deduplication. Store as a single DAG node. + +### 1.3 `token.genesis` (MintTransaction) + +The genesis is the immutable birth record of the token. It has three sub-components. + +#### 1.3.1 `token.genesis.data` (MintTransactionData) + +```typescript +{ + tokenId: string, // 64-char hex (32 bytes) + tokenType: string, // 64-char hex (32 bytes) + coinData: [string, string][], // [[coinIdHex, amountString], ...] + tokenData: string, // Usually empty string + salt: string, // 64-char hex (32 bytes) + recipient: string, // "DIRECT://..." (~80 chars) + recipientDataHash: string | null, + reason: string | null // null for regular mints, set for splits +} +``` + +- **Byte size (typical JSON):** 400-550 bytes + - `tokenId`: 66 bytes (with quotes) + - `tokenType`: 66 bytes + - `coinData`: 150-200 bytes (one coin entry with 64-char coinId hex + amount string) + - `salt`: 66 bytes + - `recipient`: ~85 bytes + - Other fields: ~50 bytes +- **Shared:** `tokenType` is shared across all tokens of the same asset class (e.g., all UCT tokens share `455ad8720656b08e8dbd5bac1f3c73eeea5431565f6c1c3af742b1aa12d41d89`). `coinData`'s coinId is shared. Everything else is unique. +- **Mutable:** No, immutable forever (genesis is written once) +- **UXF recommendation:** Separate DAG element. This is medium-sized, fully immutable, and its `tokenType` sub-field is highly shared. Could further decompose `tokenType` and `coinData` as shared leaf nodes, but the gains are marginal (64 bytes saved per token for tokenType). Keep as one DAG node with inline content. + +#### 1.3.2 `token.genesis.inclusionProof` (InclusionProof) + +This is the dominant size contributor. Structure: + +```typescript +{ + authenticator: { + algorithm: string, // "secp256k1" (~10 bytes) + publicKey: string, // 66-char hex (33 bytes compressed) + signature: string, // ~140-144 char hex (70-72 byte DER-encoded ECDSA) + stateHash: string // 64-char hex (32 bytes) + }, + merkleTreePath: { + root: string, // 64-char hex (32 bytes) + steps: [{ + data: string, // 64-char hex per step (32 bytes hash) + path: string // bit string for direction + }, ...] + }, + transactionHash: string, // 64-char hex (32 bytes) + unicityCertificate: string // Hex-encoded CBOR (variable, large) +} +``` + +**Size breakdown:** + +- **Authenticator:** ~300 bytes JSON + - `algorithm`: ~25 bytes + - `publicKey`: ~70 bytes + - `signature`: ~150 bytes + - `stateHash`: ~70 bytes +- **Merkle tree path:** Variable, depends on tree depth + - SMT has 256 levels (2^256 leaves) + - Typical path: 10-40 steps (sparse tree collapses empty subtrees) + - Each step: ~140 bytes JSON (`data` 66 chars + `path` variable) + - **Typical total: 1,400 - 5,600 bytes** +- **Transaction hash:** ~70 bytes +- **Unicity certificate (hex-encoded CBOR):** This is the largest single field + - Contains: InputRecord, ShardTreeCertificate, UnicityTreeCertificate, UnicitySeal + - CBOR tags 1007, 1008, 1001 wrap the sub-structures + - **Typical size: 1,000 - 4,000 bytes hex-encoded** (500-2000 bytes binary) + - The UnicitySeal contains BFT validator signatures (multiple validators) + +**Total inclusion proof: 2,800 - 10,000 bytes JSON (typical: ~5,000 bytes)** + +- **Shared:** The `unicityCertificate` is shared by ALL tokens committed in the same aggregator round. This is the primary deduplication target. Upper SMT path segments are also shared between tokens in the same round. +- **Mutable:** No, immutable once assigned +- **UXF recommendation:** Decompose into THREE separate DAG elements: + 1. **Authenticator** (unique per token) - separate node, ~300 bytes + 2. **MerkleTreePath** (partially shared) - separate node, with potential for sharing upper path segments + 3. **UnicityCertificate** (highly shared) - separate node, THE primary deduplication win + +#### 1.3.3 `token.genesis.destinationState` + +Referenced in the TASK.md hierarchy but in TXF format this appears to be folded into the initial `token.state`. In the SDK's `MintTransaction.toJSON()`, the destination state is the token state after genesis. It is structurally identical to `token.state` described in 1.2. + +- **Byte size:** ~400-500 bytes (same as state) +- **Shared:** No +- **Mutable:** No (historical state) +- **UXF recommendation:** Inline within the genesis DAG node or separate if the predicate pattern is shared. + +### 1.4 `token.transactions[]` (TransferTransaction[]) + +Each transfer transaction has this structure: + +```typescript +{ + previousStateHash: string, // 64-char hex + newStateHash?: string, // 64-char hex (optional, for quick lookups) + predicate: string, // Hex-encoded CBOR predicate (~300-400 chars) + inclusionProof: { // Same structure as genesis proof + authenticator: {...}, + merkleTreePath: {...}, + transactionHash: string, + unicityCertificate: string + } | null, // null = uncommitted/pending + data?: Record // Optional transfer metadata +} +``` + +- **Byte size per transaction:** ~5,500 - 11,000 bytes (when committed with proof) + - State hashes: ~140 bytes + - Predicate: ~400 bytes + - Inclusion proof: ~5,000 bytes (same analysis as genesis proof) + - Data: usually small or absent, ~0-200 bytes +- **Without proof (pending):** ~600 bytes +- **Shared components:** Same as genesis proof analysis: + - Unicity certificates shared across tokens in same round + - Upper SMT path segments shared + - Predicate algorithm identifiers shared +- **Mutable:** No, each transaction is append-only and immutable +- **UXF recommendation:** Each transaction should be its own DAG element, with its inclusion proof decomposed the same way as the genesis proof (authenticator + path + certificate as separate child nodes). + +### 1.5 `token.nametags[]` + +In TXF format: `nametags: string[]` (simplified to nametag name strings). + +In the full SDK ITokenJson: `nametags: Token[]` (recursive! each nametag is a complete token). + +- **Byte size per nametag token:** A nametag token is a full token with genesis + proof but typically zero transfer transactions. Size: ~5,500 - 8,000 bytes. +- **Shared:** The SAME nametag token appears in EVERY token that was transferred to/from a PROXY address associated with that nametag. A user with 50 tokens all received via their nametag has the same nametag token embedded 50 times. +- **Mutable:** No +- **UXF recommendation:** Critical deduplication target. The nametag token should be stored as its own complete token sub-DAG in the element pool, referenced by content hash from every parent token that embeds it. This is potentially the second-largest deduplication win after unicity certificates. + +## 2. Unicity Certificate Analysis + +### Structure + +The unicity certificate is CBOR-encoded with tagged structures: + +``` +UnicityCertificate (tag 1007) +├── InputRecord +│ ├── roundNumber: uint +│ ├── epoch: uint +│ ├── previousHash: bytes(32) +│ ├── hash: bytes(32) (SMT root hash for this round) +│ └── blockHash: bytes(32) +├── ShardTreeCertificate (tag 1008) +│ ├── shardId: bytes +│ └── merkleTreePath: [...path steps...] +├── UnicityTreeCertificate +│ ├── unicityTreeRootHash: bytes(32) +│ └── merkleTreePath: [...path steps...] +└── UnicitySeal (tag 1001) + ├── roundNumber: uint + ├── rootChainRoundNumber: uint + └── signatures: Map + ├── validator1: bytes(64-72) // ECDSA signature + ├── validator2: bytes(64-72) + └── ... +``` + +### Size Analysis + +- **InputRecord:** ~150-200 bytes CBOR (~300-400 hex chars) +- **ShardTreeCertificate:** ~200-500 bytes CBOR (depends on shard path depth) +- **UnicityTreeCertificate:** ~200-500 bytes CBOR +- **UnicitySeal:** ~300-1000+ bytes CBOR (depends on validator count) + - Each validator signature: ~70 bytes + - With 4-8 validators: 280-560 bytes just for signatures +- **Total certificate CBOR:** ~500-2000 bytes binary, **1000-4000 hex chars** + +### Sharing Statistics + +- **ALL tokens committed in the same aggregator round share the identical unicity certificate** (the certificate is a per-round object, not per-token) +- Aggregator rounds occur every ~1-2 seconds (BFT consensus interval) +- In a batch operation (e.g., wallet sync, split operation), multiple tokens are commonly committed in the same round +- Estimated sharing: in a wallet with 100 tokens, if tokens were received in batches of 5-10, approximately **10-20 unique certificates** cover all 100 tokens +- For split operations specifically, ALL resulting tokens (sender change + recipient) share the same certificate + +### Sub-component Sharing + +- **UnicitySeal:** Identical across ALL certificates from the same BFT round (even across different shards). This is the most shareable sub-component. +- **InputRecord:** Identical per round. +- **ShardTreeCertificate:** Per-shard, per-round. If all tokens are in the same shard (likely for a single user), this is shared across the round. +- **UnicityTreeCertificate:** Per-round across all shards. + +**UXF recommendation:** The certificate should be decomposed into its four sub-components as separate DAG nodes. The UnicitySeal is the most valuable sharing target as it's the largest component and identical per round. + +## 3. SMT Path Analysis + +### Structure + +```typescript +SparseMerkleTreePath { + root: string, // 32-byte hash (64 hex chars) + steps: Array<{ + data: string, // 32-byte sibling hash (64 hex chars) + path: string // Bit string indicating left/right direction + }> +} +``` + +### Path Characteristics + +- **Tree depth:** 256 levels (2^256 address space) +- **Actual path length:** 10-40 steps (sparse tree; empty subtrees are collapsed) +- **Step size:** ~140 bytes JSON per step (data hash + path bits) +- **Total path size:** 1,400 - 5,600 bytes JSON + +### Path Overlap + +Tokens committed in the same aggregator round share **upper path segments** of the SMT: +- The root hash is identical (by definition, same round = same tree) +- Path steps from the root downward are shared until the paths diverge toward different leaves +- For two random leaves in a 256-bit space, paths diverge quickly (often within 1-2 steps from the root) +- However, if `RequestId` values have any structural locality (they do -- `RequestId = SHA-256(pubkey || stateHash)`), tokens from the same user cluster somewhat in the address space + +### Practical Sharing Assessment + +- **Root hash:** Always shared within a round. But it's just 32 bytes -- not worth a separate DAG node. +- **Upper path steps:** Shared only if leaf addresses happen to be close in the 256-bit space. For random addresses, expect 0-3 shared steps before divergence. +- **Typical savings from path sharing:** Minimal for randomly-distributed leaves. Perhaps 5-15% of path data. + +**UXF recommendation:** Store the merkle tree path as a single DAG node. Splitting individual path segments provides minimal deduplication benefit and adds significant DAG complexity. The natural sharing unit is the whole path (or the whole inclusion proof). + +## 4. Predicate Analysis + +### Structure (Unmasked Predicate) + +CBOR-encoded structure containing: +``` +UnmaskedPredicate { + engine: "embedded" // Predicate execution engine + code: "unmasked_v1" // Predicate type identifier + parameters: { + tokenId: bytes(32) // Token this predicate controls + tokenType: bytes(32) // Asset class + signingAlgorithm: "secp256k1" + hashAlgorithm: "SHA256" + publicKey: bytes(33) // Owner's compressed pubkey + salt: bytes(32) // Random per-predicate + } +} +``` + +### Size + +- **Binary CBOR:** ~170-200 bytes +- **Hex-encoded:** ~340-400 characters +- **In JSON (with key):** ~420-500 bytes + +### Sharing Analysis + +- **Within same token (across states):** `tokenId` and `tokenType` are constant; `publicKey` changes on transfer; `salt` changes per state. So predicates for the same token at different states share `tokenId` + `tokenType` but differ in owner and salt. Not practically shareable as whole units. +- **Between different tokens (same owner):** `publicKey`, `signingAlgorithm`, `hashAlgorithm` are identical. But `tokenId`, `tokenType`, and `salt` differ. Not shareable as whole units. +- **Between different owners:** Nothing shared except algorithm identifiers. + +**UXF recommendation:** Keep predicates inline within their parent element (state or transaction). The algorithm identifiers (`secp256k1`, `SHA256`, `embedded`, `unmasked_v1`) are tiny constants not worth extracting. Predicates are small (~400 bytes) and rarely shared as complete units. + +## 5. Nametag Token Analysis + +### Embedding Pattern + +In the full SDK `ITokenJson`, `nametags` is an array of complete `Token` objects. A nametag token is a full token that was minted on-chain to register a human-readable name. + +A nametag token appears in: +- The `nametags[]` array of every token that was transferred using a PROXY address (nametag-based addressing) +- The user's own nametag storage (as `NametagData.token`) + +### Typical Nametag Token Structure + +```json +{ + "version": "2.0", + "state": { "data": null, "predicate": "" }, + "genesis": { + "data": { + "tokenId": "<64 hex>", + "tokenType": "f8aa13834268d29355ff12183066f0cb902003629bbc5eb9ef0efbe397867509", + "coinData": [], + "tokenData": "", + "salt": "<64 hex>", + "recipient": "DIRECT://...", + "recipientDataHash": null, + "reason": null + }, + "inclusionProof": { /* same structure as any token */ } + }, + "transactions": [], + "nametags": [] +} +``` + +- **Typical size:** 5,000 - 8,000 bytes (mostly the genesis inclusion proof) +- **Always zero transactions** (nametags are minted and never transferred) +- **Frequency of duplication:** A user with N tokens transferred via their nametag has the same nametag token embedded N times. For an active user, N could be 10-100+. + +### Deduplication Impact + +For a wallet with 50 tokens, if 40 were received via nametag: +- Without dedup: 40 * ~6,000 = **240,000 bytes** of duplicated nametag tokens +- With dedup: **6,000 bytes** (one copy) +- **Savings: ~234,000 bytes (97.5%)** + +**UXF recommendation:** This is the highest-impact deduplication target after unicity certificates. The nametag token MUST be stored as a single DAG entry referenced by hash from all parent tokens. + +## 6. Real-World Size Statistics + +### Token Size by Transaction Count + +| Transactions | Typical Size (JSON bytes) | Proof % | Certificate % | Unique Data % | +|---|---|---|---|---| +| 0 (just minted) | 6,000 - 9,000 | 70-80% | 25-40% | 10-15% | +| 1 transfer | 11,000 - 18,000 | 75-85% | 25-40% | 8-12% | +| 5 transfers | 31,000 - 54,000 | 80-88% | 25-40% | 5-8% | +| 10 transfers | 56,000 - 100,000 | 82-90% | 25-40% | 4-6% | + +### Component Size Breakdown (single token, 1 transfer) + +| Component | Typical Bytes | % of Total | +|---|---|---| +| Genesis data (tokenId, type, coinData, salt, recipient) | 500 | 3-4% | +| Genesis inclusion proof (authenticator + path) | 2,500 | 17-20% | +| Genesis unicity certificate | 2,500 | 17-20% | +| Transaction data (state hashes, predicate) | 600 | 4-5% | +| Transaction inclusion proof (auth + path) | 2,500 | 17-20% | +| Transaction unicity certificate | 2,500 | 17-20% | +| Token state (current predicate) | 500 | 3-4% | +| Nametag token (if present) | 6,000 | 40%+ | +| Version + structure overhead | 200 | 1-2% | + +**Note:** When a nametag token is embedded, it dominates the size. + +### Pool-Level Deduplication Estimates + +For a wallet with 100 tokens (mix of direct and PROXY transfers, received over 20 aggregator rounds): + +| Without UXF | With UXF (estimated) | Savings | +|---|---|---| +| Raw JSON per token: ~12,000 bytes avg | After dedup: ~4,000 bytes avg | **67%** | +| 100 tokens: ~1.2 MB | Pool total: ~400 KB | **~800 KB saved** | + +Breakdown of savings sources: +- **Unicity certificates:** ~20 unique certificates instead of 100 copies. Saves ~200 KB (50+ certificates * ~4KB each) +- **Nametag tokens:** 1-2 unique nametags instead of 60+ copies. Saves ~350 KB +- **SMT path sharing:** Minimal, ~20 KB +- **Predicate overhead sharing:** Minimal, ~10 KB + +For a 1,000-token pool, savings scale super-linearly because certificate and nametag sharing ratios improve. + +## 7. Existing Serialization Formats and Their Limitations + +### TXF Format (`types/txf.ts` + `serialization/txf-serializer.ts`) + +**What it does well:** +- Normalizes SDK byte objects to hex strings for storage +- Handles version metadata, tombstones, outbox, and nametag tracking +- Round-trips through `normalizeSdkTokenToStorage()` -> storage -> `txfToToken()` +- Supports archived and forked token variants via key prefixes + +**Limitations UXF must address:** + +1. **No deduplication:** Each token is stored as a complete, independent JSON blob (the `sdkData` string). The `TxfStorageData` map stores `_: TxfToken` with full inline content. Two tokens sharing a unicity certificate store it twice. + +2. **Flat key-value structure:** `TxfStorageData` is a flat object keyed by `_`. No hierarchical structure, no content addressing, no reference sharing between entries. + +3. **String-only nametags:** TXF simplifies `nametags` from full recursive tokens to `string[]` (nametag names only). The actual nametag token data is stored separately in `_nametag` / `_nametags`. This loses the recursive token structure needed for PROXY address verification at the token level. + +4. **No incremental updates:** Saving requires serializing the entire `TxfStorageData` object. Adding one token means rewriting the complete pool. + +5. **No content addressing:** No hashing, no CIDs, no IPLD compatibility. IPFS sync is done at the whole-document level. + +6. **No historical state extraction:** The format stores the current state and all transactions but provides no efficient mechanism to reconstruct a token at an intermediate state without parsing the full structure. + +7. **Per-wallet scoping only:** `TxfStorageData` is scoped to a single address (`_meta.address`). No support for cross-wallet token exchange bundles. + +### Wallet Text Format (`serialization/wallet-text.ts`) + +This is for wallet key backup only (master key, chain code, addresses). Not relevant to token serialization. + +### Wallet .dat Format (`serialization/wallet-dat.ts`) + +This is for importing legacy Bitcoin Core wallet files.

After T.8.D, the orchestrator-routed + path is unconditional; the dispatcher branches only on `transferMode`. + - Internal helpers `legacySingleCoinSplit()` and `legacyOutboxStub()` — + callers all migrated under T.7.C. +- `modules/payments/transfer/legacy_outbox.ts`: + - The legacy outbox decoder (`decodeLegacyOutboxBlob()` and its companion + `encodeLegacyOutboxBlob()`). Reads were already replaced by per-entry-key + readers under T.6.A; T.8.D deletes the encoder + decoder pair. +- `modules/accounting/AccountingModule.ts`: + - The `payInvoiceLegacyFallback()` private path (force-conservative legacy + coercion, replaced by T.7.D's W21 path). +- `cli/index.ts`: + - The `forceConservative` legacy-coercion branch around line 2831 + (the `transferMode = forceConservative ? 'conservative' : 'instant'` + expression remains, but the legacy fall-through guarded by + `!features.senderUxf` is removed). + +### Types + +- `types/uxf-outbox.ts`: + - `LegacyOutboxBlob` (single-blob form). The per-entry shape + `LegacyOutboxEntry` is **retained** because it is still emitted by the + backup writer and consumed by `tools/restore-legacy-outbox.ts`. +- `profile/types.ts`: + - `PROFILE_KEY_MAPPING['invalidTokens']` (the `@deprecated` legacy entry + flagged with "SHOULD be removed in T.8.D once the migration window + closes"). The per-entry-key prefix `invalid` replaces it. + +### Config / feature flags + +- `Sphere.init({ features })` continues to accept the full `UxfTransferFeatures` + shape **for compatibility** but `validateFeatures()` (T.1.B.1) now rejects + the V0–V1 configurations (legacy-only and types-widening-only). After + T.8.D the only valid configurations are V3–V7 (full UXF on both sides; + outbox in `'dual-write'` or `'uxf'` mode). + +### NOT removed in T.8.D (deferred) + +The following are explicitly **left in place** by T.8.D and tracked for a +future cleanup PR: + +- `tools/restore-legacy-outbox.ts` — kept indefinitely as the back-out path. +- `LegacyOutboxEntry` type — required by the restore tool. +- `${addr}.legacyOutbox.backup` profile entries — operators may delete after + 90 days post-cutover at their discretion (no automated GC). +- `features.outbox === 'dual-write'` — kept for one release after T.8.D so + wallets mid-migration can complete the transition without flipping straight + to `'uxf'`. + +A follow-up PR `T.9-legacy-outbox-final-removal` is on the roadmap (no committed +date) to delete the restore tool, the `LegacyOutboxEntry` type, and the +`'dual-write'` outbox mode. + +--- + +## Feature flag flips + +T.8.D flips the **defaults** of the feature flag matrix.

Passing any combination outside V3–V7 throws +`INVALID_FEATURE_COMBINATION` at init time. The 8-row valid-combination matrix +in `UXF-TRANSFER-IMPL-PLAN.md` §7.A is unchanged; only the **default** moves +from V1 → V5 (V5 = full UXF on both sides + dual-write outbox). + +**Override per-flag.** Operators can pin a specific flag to `false` in +`Sphere.init({ features })` for a single wallet. This is the **per-flag +surgical rollback** path (W42). Example, to disable the recovery worker on a +problem wallet without reverting cutover: + +```typescript +Sphere.init({ + ...providers, + features: { recoveryWorker: false }, // others use new defaults +}); +``` + +Override is **deprecated for `senderUxf` / `recipientUxf`** — passing `false` +for either now throws because the legacy paths are deleted. + +--- + +## Rollout + +T.8.D rolls out in three phases. Each phase has a hard pause-point with +explicit go/no-go criteria. + +### Phase 1 — Testnet (24h soak) + +1. Merge T.8.D PR to `main`.

Set `features.senderUxf=false` and +`features.recipientUxf=false` on affected wallets to re-enable the +dispatcher fork's legacy branch. The reverted SDK version flows through +the normal release channel. + +### Step 2 — Restore migrated wallets (if needed) + +T.6.D's outbox migration is **one-way** at the data level. Wallets that +already migrated to the per-entry-key outbox have their legacy entries on +disk only as a backup snapshot at `${addr}.legacyOutbox.backup`. After PR +revert, these wallets boot with legacy code that does NOT see the new +per-entry-key entries — they appear empty. + +Run `tools/restore-legacy-outbox.ts` per affected wallet: + +```bash +# Dry-run first (mandatory — never run live without classifying entries) +npx tsx tools/restore-legacy-outbox.ts \ + --addr \ + --profile-path \ + [--encryption-key ] \ + --dry-run + +# If the dry-run output looks correct, run live (no --dry-run) +npx tsx tools/restore-legacy-outbox.ts \ + --addr \ + --profile-path \ + [--encryption-key ] +``` + +**Flags:** + +| Flag | Meaning | +| --- | --- | +| `--addr ` | **Required.** The `${addr}` prefix used in the migration (e.g., `DIRECT_aabbcc_ddeeff`). | +| `--profile-path ` | **Required.** Path to the wallet's OrbitDB store directory. | +| `--encryption-key ` | Optional. AES-256 key (64 hex chars) for encrypted profiles. The script uses the same key to RE-encrypt restored values. | +| `--dry-run` | Read + classify entries; do not write. Exits 0. **Always run first.** | +| `--clear-sentinel` | Also delete `${addr}.legacyOutbox.migrated`, allowing the migration to re-run on next boot. **Recommended only when fully rewinding.** Default: keep the sentinel. | +| `--quiet` | Print JSON result only. | + +**Idempotency.** Re-running the restore on the same wallet is a no-op for +already-restored entries. The script classifies each entry as +`would-restore | already-restored | mismatch` and surfaces the counts in +the result JSON. + +**Sentinel handling.** By default the migration sentinel +(`${addr}.legacyOutbox.migrated`) is **NOT cleared**. This is intentional: +restore is a recovery action and the operator presumably wants the +migration to NOT re-run on the next boot (otherwise the restore is +immediately undone). Pass `--clear-sentinel` only when fully rewinding to +pre-migration state and re-allowing the migration. + +**Round-trip property (C7).** The restore script's correctness is gated by +`tests/integration/profile/legacy-outbox-restore-roundtrip.test.ts`. The +test plants legacy entries → migrates → restores → asserts byte-identity. +This test is a **hard merge gate** for T.8.D — if the round-trip fails, +the back-out path is unsound and cutover MUST NOT ship. + +**"Byte-identical" definition.** Excludes Lamport stamps, `observedAt` +timestamps, `_schemaVersion`, and sentinel keys. See +`UXF-TRANSFER-IMPL-PLAN.md` §8 item 14 for the explicit field-list. + +### Step 3 — Verify and close the incident + +After revert + restore: + +- Re-run the restore script with `--dry-run` on each affected wallet — output + should show `would-restore: 0, already-restored: N, mismatched: 0`. +- Confirm `transfer:*` event volumes return to pre-cutover baseline. +- Open a postmortem issue; tag with the `uxf-transfer-rollback` label so + follow-up cleanup PRs can reference it. + +--- + +## Known limitations + +These are post-cutover items the user explicitly chose to ship as v1 +limitations rather than defer cutover. Each is tracked in the source for +visibility. + +### Semaphore released around `sleep` (intentional for backpressure) + +The finalization-worker base (`modules/payments/transfer/finalization-worker-base.ts`) +holds the per-aggregator + per-token semaphore across the FULL poll loop — +including the `sleep()` call between poll attempts. The worker does NOT +release the permit during sleep. + +**Why:** releasing across sleep would let a stampede of waiting workers +flood the aggregator the moment the first sleeping worker yields. Holding +the permit through sleep provides backpressure: the aggregator sees at most +N concurrent pollers per token regardless of contention. + +**Limitation:** under sustained slow-aggregator response times, throughput +is bounded by `MAX_AGG_PERMITS / poll_loop_duration` rather than by the +worker count. Operators can raise `MAX_AGG_PERMITS` per aggregator if the +soak metrics show poll-bound saturation. + +This is **not a bug** — it's the correct backpressure choice per Phase 6 +review. Do NOT "fix" it without an ADR. + +### Restore script is one-shot per wallet + +`tools/restore-legacy-outbox.ts` operates on a single wallet at a time. +Multi-wallet bulk restore is out of scope; operators script the loop +themselves (one `npx tsx tools/restore-legacy-outbox.ts` invocation per +`addressId`). + +### Per-process semaphore registry + +The per-aggregator semaphore registry in `modules/payments/transfer/aggregator-semaphores.ts` +is per-process. Multi-process wallets sharing one OrbitDB store are out of +scope for v1.0 (same scope decision as ADR-005). + +### Profile encryption key handling on restore + +`--encryption-key` accepts the AES-256 key as a hex string on the CLI. +JS strings cannot be zeroized, so the key leaks to GC for the script's +lifetime. Acceptable for a one-shot recovery script; do **not** wrap the +restore in a long-running daemon. Spawn a fresh process per wallet. + +--- + +## External-acks gate + +T.8.D depends on a non-code gate: three external integrator repos must +close their `uxf-transfer-v1-ack`-labeled tracking issues before merge. + +### CI mechanism + +`.github/workflows/external-acks-gate.yml` runs as a **required check** on +the T.8.D PR. The workflow uses `gh` to query each repo: + +```bash +gh issue list \ + --state closed \ + --search "label:uxf-transfer-v1-ack" \ + --repo unicity-sphere/sphere +# (and same for unicitynetwork/openclaw-unicity) +``` + +If any query returns an empty list, the workflow **fails** and the PR +cannot be merged.

T.8.D removes the legacy entirely. **T.6.D.2 restore script is the back-out path (C7 applied).** +13. **Continuity walker is mandatory at receive (C8 applied)**: T.3.B.1 includes a full-chain source-state continuity walker; `'continuity-broken'` reason is wired end-to-end.

Scope and Goals + +This document defines the wire-level protocol by which one Sphere wallet transmits one or more tokens to another wallet, using **UXF bundles as the default inter-wallet wire format**. The legacy per-token TXF wire shape remains available as a permanent explicit opt-in. It specifies: + +1. The two **finalization modes** (`'instant'` and `'conservative'`) and how they compose with the two **wire shapes** (UXF bundle and legacy TXF). Finalization mode and wire shape are orthogonal — every combination is supported except instant TXF on legacy peers that lack `txfFinalization` awareness (in that case the sender falls back to conservative TXF automatically). +2. The wire payload variants for UXF — **CAR-embedded** (small bundles, default cap 16 KiB) and **CID-referenced** (large bundles pinned to IPFS), with per-call sender overrides (`force-inline` / `force-cid` / custom byte threshold). +3. The sender-side state machine, including outbox semantics for instant-mode follow-up finalization (which may need to resolve multiple pending transactions per token, not just the latest). +4. The recipient-side **disposition decision matrix** — what happens to each token in the received bundle under every meaningful combination of (chain validity, current-state predicate target, finalization status of every transaction in the history, oracle spent state). +5. The async-finalization workers on both sides, plus convergence guarantees when sender and recipient finalize independently OR when the same token reaches the receiver via two channels with overlapping but partially-finalized histories. +6. **Chain mode** — the operational situation where instant-mode forwarding accumulates multiple unfinalized transactions in a token's history. Not a separate mode; just a property of the chain at receive time. See §2.3. +7. Replay / duplicate handling (idempotent — re-processing the same bundle is wasted compute, not a correctness issue). +8. Permanent acceptance of legacy wire shapes — the recipient indefinitely accepts `{sourceToken, transferTx}`, V6 `COMBINED_TRANSFER`, and `INSTANT_SPLIT` events without deprecation. Received TXF tokens still merge into the UXF-based OrbitDB profile when one is enabled. + +### 1.1 Non-goals + +- Aggregator-scan-based discovery of inbound transfers (the recipient relies on the Nostr TOKEN_TRANSFER event; if delivery fails permanently, recovery is out of scope here). +- Refund / reversal protocol on instant-mode finalization failure (spec deferred — see §9.4). +- Cross-chain or cross-network transfers. + +--- + +## 2. Transfer Modes + +Sphere supports two **finalization modes** (`'instant'` and `'conservative'`) that are orthogonal to two **wire shapes** (UXF bundle and legacy TXF). The default is `'instant'` over UXF (see §2.5). The mode/shape matrix: + +| Mode | Wire | When | +|---|---|---| +| `'instant'` | UXF (default) | Default. Zero latency on send; both parties finalize asynchronously. | +| `'conservative'` | UXF | Sender awaits proof for every unfinalized transaction in the bundle before delivering. | +| `'instant'` | TXF (`transferMode: 'txf'`, with `txfFinalization: 'instant'`) | Legacy per-token wire shape, async finalization. | +| `'conservative'` | TXF (`transferMode: 'txf'`, default `txfFinalization: 'conservative'`) | Legacy per-token wire shape, fully finalized before send. | + +### 2.1 Instant Mode (default) + +The sender submits the commitment to the aggregator but **does not await the proof**. The bundle contains the transaction with `inclusionProof: null` PLUS the **fully signed transfer-tx**. Only the source-state owner can sign; the bundle MUST carry the signed tx so the recipient (and any later forwarder) can re-derive the commitment requestId and poll the aggregator independently. + +> **Why the bundle MUST carry the signed tx in instant mode**: the commitment requestId is computed from the signed tx + source state — both sides can compute it. What the recipient cannot do is produce the signed tx for the sender; only the source-state owner can sign. Shipping the signed-but-unproven tx is what makes asynchronous independent finalization possible. + +> **Token-hash invariance** (verified against `@unicitylabs/state-transition-sdk`): the token's identity (`token.id`) derives from `genesis.data.tokenId` and is **immutable across proof attachment**. `TransferTransactionData.calculateHash()` (`TransferTransactionData.js:92-93`) feeds only `(sourceState, recipient, salt, recipientDataHash, message, nametags)` — explicitly excluding the inclusion proof. Attaching a proof changes the *CBOR serialization* of the token and therefore its *content-address (CID)*, but neither the token identity nor any per-transaction data hash. This is the property that makes split-then-send-instantly safe: a child token minted from a still-pending parent has stable identity even after the parent is later finalized. + +``` +Sender Aggregator Recipient + │ │ │ + │ submit commitment │ │ + ├─────────────────────────────▶│ │ + │ ◀── 200 OK (no proof yet) ───┤ │ + │ │ │ + │ build UXF bundle with │ │ + │ signed transfer-tx, │ │ + │ inclusionProof: null │ │ + │ │ │ + │ send TOKEN_TRANSFER ─────────────────────────────────────▶│ + │ │ │ + │ │ merge as 'pending' │ + │ │ │ + │ async finalize worker │ async finalize worker │ + │ (re-)submit + fetch proof ──│ ◀──── (re-)submit + fetch │ + │ attach proof │ attach proof │ + │ status: confirmed │ status: valid │ + │ │ │ +``` + +**Recipient guarantee:** the bundle is structurally validated, the chain is verified (modulo any still-unfinalized transactions), and the current-state predicate target is checked.

This is not a fourth `transferMode` value — it's a property of the token's transaction history at the moment of receive. + +**Source-side opt-in** (`allowPendingTokens`): the sender's `payments.send()` call accepts an `allowPendingTokens?: boolean` option (default `false`). When `false` (default), the source-token selector considers ONLY tokens with `manifest.status === 'valid'` (fully finalized) — chain mode never arises from local sends. When `true`, the selector MAY pick `pending` tokens to satisfy the requested amount. Selection priority is strict: + +1. **First, satisfy the requested amount from `valid` (finalized) tokens.** Only if the finalized inventory cannot cover the requested `(coinId, amount)` does the selector spill over to step 2. +2. **Then, top up the shortfall from `pending` tokens** in arrival order (oldest pending first), each contributing whatever balance it has of the requested coin. + +The result: an `allowPendingTokens: true` send produces chain-mode transfers only when finalized funds are insufficient — never to "use pending preferentially." If after both steps the requested amount is still uncovered, `send()` rejects with `INSUFFICIENT_BALANCE` (the SDK does NOT attempt to send a partial amount). + +A receiver may be handed a token with K unfinalized transactions in its history (K ≥ 1) when: + +- The original sender used instant mode WITH `allowPendingTokens: true` and the source token was itself pending (1 or more unfinalized inherited from a chain-mode ancestor). +- The original sender used instant mode (1 unfinalized: the latest transfer). +- The original recipient forwarded the token in instant mode before its inherited tx finalized (now 2+ unfinalized). +- This forwarding repeated arbitrarily many times — the chain grows. + +Such tokens are useful for **high-frequency / semi-trusted scenarios** where parties accept short-term double-spend exposure in exchange for zero-latency settlement. + +**Convergence to `valid`** for a chain-mode token requires either: + +1. **Independent finalization** — the local finalization worker walks the entire history, polls (and if necessary re-submits) every unfinalized commitment, and attaches every proof as it arrives. K aggregator round-trips, each idempotent. OR +2. **Merge with a more-finalized copy** — the same token (same `token.id`) arrives via another channel (backup import, second Nostr delivery, peer reconciliation) carrying additional inclusion proofs. The local pool merges the two UXF representations under Wave G.3 enrichment rules: any proof one side has and the other lacks is grafted in. Convergence is monotonic — proofs accumulate, never delete. + +The recipient's job is to attempt finalization on **every** unfinalized transaction in the history, not only the latest one. A token with even one unresolved transaction is held at status `'pending'`. + +### 2.4 TXF Wire Shape (legacy, explicit opt-in) + +The sender ships one Nostr `TOKEN_TRANSFER` event **per token** using the legacy payload shape (`{sourceToken, transferTx}`, V6 `COMBINED_TRANSFER`, or `INSTANT_SPLIT` per existing SDK selection logic). No UXF bundle is constructed. TXF is **permanent**, not deprecated. Senders use it only when the caller explicitly passes `transferMode: 'txf'`. + +**TXF is orthogonal to finalization mode** — a TXF transfer can be either instant (`txfFinalization: 'instant'`) or conservative (default `txfFinalization: 'conservative'`). The semantics of each finalization mode (§2.1, §2.2) apply identically; only the wire shape differs. + +**Recipient behavior when receiving TXF:** if the recipient has an OrbitDB-based UXF profile enabled, TXF arrivals are still merged into the UXF profile via an internal adapter (one TXF event → one synthetic single-token UXF disposition pass through the §5.3 decision matrix). The recipient need not maintain a parallel TXF-only inventory. Token statuses, dispositions, and storage outcomes are identical to the UXF-bundle path. + +**TXF lacks the multi-token bundle benefit** — N tokens means N Nostr events. Use only when the caller has a deliberate reason (peer interop with non-UXF wallets, diagnostic forensics, backward-compatibility regression coverage). + +### 2.5 Mode Selection + +- **Default**: `transferMode: 'instant'` over UXF, `allowPendingTokens: false` — instant UXF non-chained. Minimizes UX latency; uses only finalized source tokens. +- **Caller override**: `PaymentsModule.send({ transferMode, txfFinalization?, delivery?, allowPendingTokens? })`. + - `transferMode: 'instant'` (default) — UXF bundle, async finalization (§2.1). + - `transferMode: 'conservative'` — UXF bundle, full-history finalization-before-send (§2.2). Recommended for high-value transfers, escrow, swap deposits. + - `transferMode: 'txf'` — legacy per-token wire (§2.4). Pair with `txfFinalization: 'instant' | 'conservative'` (default `'conservative'`). + - `allowPendingTokens: false` (default) — source-token selector considers only `valid` tokens; `INSUFFICIENT_BALANCE` if finalized funds don't cover. + - `allowPendingTokens: true` — selector may spill over to `pending` tokens after exhausting `valid` ones. Enables chain mode (§2.3). Selection priority is strict: finalized-first, then pending-by-age. +- **Splits MAY be instant**: token-hash invariance under proof attachment (verified above) means split-and-mint flows can issue child tokens with status `'pending'` referencing a still-unfinalized parent. The parent's proof, when later attached, does not invalidate the child's identity. This is a **deliberate change** from the prior assumption that splits required conservative-mode finalization. +- **Forced conservative remains** for cross-protocol bridges (e.g., into a non-UXF chain) where the destination requires finalized state. The implementation surfaces such overrides in the call result. `allowPendingTokens` is silently coerced to `false` in forced-conservative paths since pending tokens cannot be conservatively-shipped (their predecessor txs aren't finalized). + +--- + +## 3.

The CAR bytes are base64-encoded into the Nostr event content. No IPFS round-trip required. + +**Recipient action**: base64-decode → `UxfPackage.fromCar(bytes)`. CAR root CID MUST equal `payload.bundleCid` (sender lied → reject). + +### 3.3 `kind: 'uxf-cid'` — large bundles, plus per-call delivery overrides + +Used when the CAR exceeds the inline cap. Sender pins the CAR to IPFS, then sends ONLY the CID over Nostr. + +> **The CAR is in fact already pinned by the time we send.** Per PROFILE-ARCHITECTURE.md §10.12, the outbox is part of the sender's UXF profile, which is itself published to IPFS (with IPNS naming). Writing the bundle to the outbox before send already persists it to the local Helia/IPFS node and republishes the profile. The "pin step" referenced here is a no-op when the profile pipeline has already run; it is named explicitly only to give the recipient a guaranteed retrievable CID. + +**Recipient action**: `fetchCarFromGateway(payload.bundleCid)` via the same verified-CAR pipeline already established for IPNS-reader migration (Wave G.5 / I.b). The verified CAR is then loaded via `UxfPackage.fromCar(bytes)`. + +**Gateway resilience**: the recipient walks its own configured gateway list; `senderGateways` is informational only (a hostile sender could lie). The Wave G.5 verifier ensures gateway-served bytes hash correctly against the requested CID. + +#### 3.3.1 Per-call sender overrides + +By default the sender selects `'uxf-car'` if `carBytes.length <= 16 KiB` else `'uxf-cid'`. The caller MAY override this on a per-`send()` basis: + +```typescript +type DeliveryStrategy = + | { kind: 'auto'; inlineCapBytes?: number } // default; cap defaults to 16 KiB + | { kind: 'force-inline' } // always uxf-car (errors if too large for the relay's max event size) + | { kind: 'force-cid' }; // always uxf-cid even for tiny bundles +``` + +`PaymentsModule.send({transferMode: 'instant', delivery: {...}})`: +- `delivery: { kind: 'auto' }` (default if omitted) — 16 KiB cutoff. +- `delivery: { kind: 'auto', inlineCapBytes: 32_768 }` — auto with custom cutoff. +- `delivery: { kind: 'force-inline' }` — sender insists on inline regardless of size; if the resulting Nostr event exceeds the relay's max payload, the send fails with `INLINE_CAR_TOO_LARGE`. +- `delivery: { kind: 'force-cid' }` — sender insists on pinning even for tiny bundles (e.g., when the receiver is known to be storage-constrained or when the operator wants every bundle indexed by CID for audit). + +**Hard upper bound**: regardless of `inlineCapBytes`, the implementation enforces a fixed conservative ceiling of **96 KiB** for inline CAR bytes. This is the safe default for typical Nostr relay deployments. If the caller provides `delivery: { kind: 'auto', inlineCapBytes: N }` with `N > 96 KiB`, the SDK MUST silently clamp `inlineCapBytes` to 96 KiB — auto mode never publishes inline above the relay-safe ceiling regardless of user override. Implementations MAY instead reject such a configuration with `INVALID_INLINE_CAP` at startup; the choice is implementation-defined but the clamp/reject behavior MUST be deterministic. + +> **NIP-11 relay-discovery is NOT in scope for v1.0.** A future revision MAY probe the publishing relay's NIP-11 `limitations.max_message_length` to dynamically size the ceiling, but the current `transport/NostrTransportProvider.ts` does not implement NIP-11. Implementations MUST use the fixed 96 KiB cap until the discovery extension lands (deferred — §12.2). + +Publish-time rejection handling: if a `force-inline` send is attempted within the 96 KiB cap but the chosen relay still rejects on publish (relay-specific limit lower than the default, or temporary capacity issue), the publish failure is treated as `failed-transient` (§7.0). For `delivery: 'auto'` senders, the worker auto-falls-back to `uxf-cid` on retry. For `delivery: 'force-inline'` senders, the failure surfaces — the caller chose force-inline explicitly and must handle the relay-rejection branch. + +**Fetched-CAR size cap (recipient-side)**: when fetching via `kind: 'uxf-cid'`, the recipient enforces a maximum fetched-CAR size of **32 MiB** by default (configurable). Fetches whose Content-Length or running byte count exceeds the cap are aborted with `FETCHED_CAR_TOO_LARGE`. This is a DoS defense against malicious senders pinning huge CARs. + +#### 3.3.2 Delivery-completion semantics (normative) + +The sender's outbox can only mark a transfer "complete" (status `delivered` or `delivered-instant`, eligible for GC) once specific conditions are met. The recipient's "delivered" state is reached at a different point. These semantics differ between inline and CID delivery: + +**Inline delivery (`kind: 'uxf-car'`)**: +- **Sender** considers the bundle delivered as soon as the Nostr publish is acknowledged by at least one configured relay (the relay durably persisted the encrypted event). The CAR bytes traveled inside the Nostr event itself; no separate IPFS persistence is required. Outbox transitions `sending → delivered` (or `delivered-instant`). +- **Recipient** considers the bundle delivered when the Nostr event arrives, decryption succeeds, and `UxfPackage.fromCar(base64Decode(payload.carBase64))` returns successfully (i.e., the CAR parses and the root CID matches `payload.bundleCid`). No external network fetch is required. + +**CID delivery (`kind: 'uxf-cid'`)**: +- **Sender** considers the bundle delivered ONLY AFTER both of the following are confirmed: + 1. The CAR has been persisted to IPFS — the local Helia node OR an external pinning service has acknowledged the pin AND the CID is retrievable via at least one verifiable route. + 2. The Nostr event carrying the CID reference has been acknowledged by at least one relay. + Both confirmations are required because either alone is insufficient: a Nostr event referencing an unpinned CID is undeliverable; a pinned CID with no Nostr notification leaves the recipient unaware. The sender's outbox MUST NOT transition `sending → delivered` (or `delivered-instant`) until both confirmations land. Implementations MAY use an intermediate `pinning` sub-state during the IPFS-persist phase (already in §7.0 transition table). +- **Recipient** considers the bundle delivered ONLY when **physically syncing the bundle from IPFS by the CID received via Nostr**. Receiving the Nostr event alone does NOT constitute delivery — the recipient must successfully fetch the CAR from IPFS (with the §3.3.1 32 MiB cap and verified-CAR pipeline) before any state transitions occur. If the IPFS fetch fails for all configured gateways within retry budget, the bundle is NOT delivered; the recipient emits `transfer:fetch-failed` and does not acknowledge the sender. This semantics applies BOTH for instant and conservative modes. + +**Outbox cleanup**: a "completed" UXF bundle transfer (status `delivered` for conservative/TXF, or `finalized` for instant) MAY be safely removed from the outbox per the retention window (§7.0 `delivered → expired` transition). For CID delivery, "completed" requires BOTH the IPFS pin AND Nostr publish acknowledged — never one alone. + +Test cases for these semantics are enumerated in §11.2 (integration tests). + +### 3.4 TXF (legacy) wire shape + +`'txf'` mode does NOT use `UxfTransferPayload`. The sender emits one Nostr `TOKEN_TRANSFER` event per token with the existing legacy payload shapes: + +- `{sourceToken, transferTx, memo?, sender?}` — Sphere TXF (current default in the codebase pre-this-spec). +- `{type: 'COMBINED_TRANSFER', version: '6.0', ...}` — V6 multi-token combined. +- `{type: 'INSTANT_SPLIT', version: '4.0' | '5.0', ...}` — split-output transfers. +- `{token, proof}` — SDK legacy shape. + +Recipients indefinitely accept all of the above (see §10). Senders only emit them when `transferMode: 'txf'` is explicitly set. + +--- + +## 4. Sender Flow + +### 4.1 Bundle construction (common to both modes) + +Inputs: `tokens: Token[]` (selected for transfer), `recipient: PeerInfo`, `transferMode: 'conservative' | 'instant'`. + +**Canonical asset model** (per the underlying Unicity state-transition SDK; verified against `@unicitylabs/state-transition-sdk` `lib/transaction/split/TokenSplitBuilder.js`, `lib/transaction/TransferTransactionData.d.ts`, `lib/token/Token.d.ts`): + +- A **coin token** is a token with non-empty `coinData` carrying one or more `(coinId, amount)` entries. Coin tokens MAY be split: the SDK's `TokenSplitBuilder` consumes the source via burn-then-mint and produces N new outputs, each with a fresh `tokenId`. The builder enforces (a) every output has non-empty `coinData`, (b) the union of output coin types equals the parent's coin types exactly (no dropping a coin type), (c) per-coin amounts are conserved across outputs. +- An **NFT token** is a token with empty / null `coinData`, distinguished solely by its unique `tokenId`. NFT tokens CANNOT be split (the split builder rejects empty-coinData inputs). NFT tokens are transferred WHOLE via `TransferTransaction` — the source `tokenId`, `tokenType`, and identity data are preserved verbatim; only the current-state predicate changes. + +**Class predicate (normative)** — implementations MUST use exactly this rule to classify a token at runtime: + +``` +isNft(token: Token): boolean = + token.coins === null || token.coins === undefined || token.coins.length === 0 +``` + +where `token.coins` is the post-prune list of fungible coin entries. Implementations MUST prune zero-amount entries (`amount === '0'`) from `coinData` at ingest time (deserialization from CAR or storage) so that the class predicate is stable. A token with `coinData: [{coinId, amount: '0'}]` MUST be normalized to `coinData: []` before the class check fires. This avoids the ambiguous case where `[{amount: '0'}]` could be classified inconsistently across implementations. + +> **Note on common NFT patterns**: this protocol's NFT model is "empty coinData" — distinct from the Ethereum-NFT-as-balance-of-1 pattern (where `coinData: [{coinId: , amount: '1'}]` represents the NFT). Tokens following the Ethereum pattern are CLASSIFIED AS COINS by this protocol's predicate (non-empty coinData) and transferred via split, not whole-token. If a future revision adds explicit support for the Ethereum-style pattern, it would require a new asset kind discriminator (e.g., `kind: 'erc1155-balance'`) extending the union per §10.4. +- **No mixed-asset tokens**: this protocol does NOT permit a single token to carry both a non-empty `coinData` AND a separable "NFT identity." Every token's `tokenId` is unique by construction, but the protocol treats a token as one OR the other, not both. A future protocol revision MAY introduce a primitive that preserves `tokenId` while modifying `coinData`; until then, attempts to model mixed-asset tokens are out of scope. + +This canonical model has direct consequences for §4.1 below: NFT transfers are always whole-token (no split, no change); coin transfers may split but never produce empty-coinData outputs; the two operations cannot be combined on a single source token. + +1. **Validate inputs** — the request carries one or more **asset targets**, each of which is either a fungible coin slice or a whole-token (NFT) reference. + + ```typescript + type AssetTarget = + | { kind: 'coin'; coinId: string; amount: string } // fungible + | { kind: 'nft'; tokenId: string }; // whole-token / NFT + ``` + + The target list is constructed from the `TransferRequest`: + - Primary slot (`coinId` + `amount`): both fields are OPTIONAL. If both are present, prepend `{ kind: 'coin', coinId, amount }` to the target list. If both are absent, the request has no primary entry. (Note: the `coinId` and `amount` fields remain *required by the type* in the SDK's TransferRequest declaration for backward compatibility with v1.0 callers; semantically they are optional from the protocol's perspective, and the implementation wave will extend the type to optional fields explicitly.) + - `additionalAssets`: each entry's `kind` discriminator selects between coin and NFT shapes; appended to the target list verbatim. + - Resulting `targetList = [primaryIfPresent, ...additionalAssets]`. + + Validation: + - If `targetList.length === 0` → `EMPTY_TRANSFER` rejection. + - `additionalAssets === undefined` and `additionalAssets === []` are semantically identical (both reduce the target list to `[primaryIfPresent]`). + - **Discriminator forward-compat**: receivers MUST reject any `additionalAssets` entry whose `kind` is not in the union recognized by the implementation (`UNKNOWN_ASSET_KIND`). Silent skip would change transfer semantics. Senders MUST NOT include unrecognized kinds when targeting a recipient who advertises an older protocol version. + - All `kind: 'coin'` entries' `coinId` values MUST be distinct, INCLUDING the primary slot's `coinId` if present. Duplicates → `INVALID_REQUEST` (the caller should sum into one entry — typically the primary). + - All `kind: 'nft'` entries' `tokenId` values MUST be distinct. Duplicates → `INVALID_REQUEST` (cannot transfer the same NFT twice in one call). + - Each `kind: 'coin'` entry's `amount` MUST be > 0 (no exceptions; no placeholder convention). + - All source tokens MUST be currently owned (current-state predicate binds to sender). + - **Coin-target coverage**: for each `kind: 'coin'` target `(coinIdᵢ, amountᵢ)`: the union of coin source tokens MUST collectively contain at least `amountᵢ` of `coinIdᵢ`. A single coin source token MAY contribute to multiple coin targets if it carries multiple of the requested coin types. + - **NFT-target coverage**: for each `kind: 'nft'` target `{tokenId}`: the sender's pool MUST contain an NFT token (empty/null coinData) with that exact `tokenId` whose current state binds to the sender. If a token with the requested `tokenId` exists but has non-empty coinData (i.e., it's a coin token, not an NFT), reject with `INSUFFICIENT_BALANCE` reason='nft-not-owned' — coin tokens cannot satisfy NFT targets. + - **Asset-class disjointness**: NFT and coin source tokens are disjoint sets — a single source token contributes to either coin targets OR an NFT target, never both. + - If any target is uncoverable, `send()` rejects with `INSUFFICIENT_BALANCE`. Partial shipment is never attempted. + +2. **Compute splits / build transfer transactions**. The protocol has TWO independent operations, applied per source token: + + **NFT source (empty-coinData token, satisfies one `kind: 'nft'` target)**: build a `TransferTransaction` that state-transitions the source whole to the recipient. The recipient receives a token with the SAME `tokenId`, `tokenType`, and identity data as the source — only the current-state predicate changes. No split. No change token. + + **Coin source (non-empty-coinData token, contributes slices to one or more `kind: 'coin'` targets)**: apply the SDK's `TokenSplitBuilder`: + - **`tokenForRecipient`**: contains EXACTLY the slices this source token contributes to the target list. If the source contributes to multiple coin targets (it carries multiple requested coin types), `tokenForRecipient` carries multiple coin entries. The recipient token has a FRESH `tokenId` (split mints a new token). + - **`changeToken`**: contains everything left in the source AFTER subtracting all contributed slices: (a) the unrequested portion of any contributed coin, (b) all non-requested coin types in the source. The change token has a FRESH `tokenId` and is minted to the sender's identity. + - **Builder invariants enforced** (per `TokenSplitBuilder.js`): + - Every output MUST have non-empty `coinData`. The protocol satisfies this by construction: `tokenForRecipient` carries at least one slice (it satisfies a coin target); `changeToken` carries the remainder (non-empty unless the source's contributed slices exactly equal its total, in which case there is no change token at all — a `TokenSplitBuilder` operation with a single output equivalent to the source's amounts ). + - Output coin types ⊆ parent coin types; per-coin sums conserved. + - **Whole-source-amount special case**: if a coin source's total balance for a coin equals the requested slice, AND the source carries no other coin types (i.e., the slice consumes the source entirely), the SDK MAY use a single state-transition (no split, no change) instead of a split-with-change. Implementation-defined optimization. + + **Source-class enforcement**: the implementation MUST verify each source token's class (NFT vs coin) BEFORE building transactions. Citing an NFT source for a coin target (or vice versa) is a programming error and SHOULD be caught at validation (§4.1 step 1) — but the per-source operation here is a final guard. + + **Worked examples**: + - **Single-coin transfer** (source `{UCT:100}`, target `(coin, UCT, 30)`) → split: recipient `{UCT:30}` (fresh tokenId), change `{UCT:70}` (fresh tokenId). + - **Single-coin transfer from multi-coin source** (source `{UCT:100, USDU:50}`, target `(coin, UCT, 30)`) → split: recipient `{UCT:30}`, change `{UCT:70, USDU:50}`. Non-requested USDU carried entirely into change. + - **Multi-coin transfer covered by ONE source** (source `{UCT:100, USDU:50, ALPHA:1000}`, targets `(coin, UCT, 30) + (coin, USDU, 20)`) → split: recipient `{UCT:30, USDU:20}`, change `{UCT:70, USDU:30, ALPHA:1000}`. + - **Multi-coin transfer covered by MULTIPLE sources** (source A `{UCT:100}`, source B `{USDU:50}`, targets `(coin, UCT, 30) + (coin, USDU, 20)`) → split A: recipient-A `{UCT:30}` + change-A `{UCT:70}`; split B: recipient-B `{USDU:20}` + change-B `{USDU:30}`. Recipient gets TWO child tokens; bundle carries both. + - **NFT-only transfer** (source NFT-token `Tᴺ` with empty coinData, target `(nft, tokenId=Tᴺ.id)`) → whole-token state-transition: recipient gets `Tᴺ'` with `tokenId=Tᴺ.id` preserved, coinData still empty, current state binds to recipient. No split, no change token. + - **Mixed coin + NFT bundle (separate sources)** (source A `{UCT:100}`, NFT source B with empty coinData; targets `(coin, UCT, 30) + (nft, tokenId=B.id)`) → split A: recipient-A `{UCT:30}` + change-A `{UCT:70}`; whole-transfer B: recipient-B `B'` (preserved id). Recipient gets two child tokens; bundle carries both. Change is one token `{UCT:70}`. + + **NOT supported** (do not appear in the worked examples; would require a future protocol primitive): + - Extracting an NFT identity from a coin-bearing source while leaving coins behind. The current SDK split mints fresh `tokenId`s, breaking identity preservation; whole-token transfer of such a source ships the coins along with the NFT. + - Combining a coin slice and an NFT identity into a single recipient token. Each source's transaction is independent; coin slices and NFT identities arrive as separate tokens. + + - Splits MAY be issued in instant mode (the parent's still-pending transaction does not invalidate child token identities — see the token-hash invariance note in §2.1). The `splitParent: tokenId` reference is recorded on each child for §6.1.1 cascade purposes. + + **NFT cascade asymmetry warning** (operational, not a protocol error): when `allowPendingTokens: true` is combined with NFT targets, a pending NFT source CAN be transferred in chain mode. If the source's predecessor tx hard-fails, §6.1.1 cascade marks the recipient's NFT invalid. **Coin cascades cost fungible value (replaceable from elsewhere); NFT cascades cost non-fungible identity (irrecoverable — no other peer can produce the same `tokenId`)**. Implementations SHOULD warn the caller when an NFT target is satisfied by a pending source — the caller MAY pass `confirmNftPending: true` to acknowledge the risk explicitly. (Defaults: `confirmNftPending: false`; sending pending NFTs without explicit acknowledgement → `NFT_PENDING_REQUIRES_CONFIRMATION` rejection.) + +> **Multi-asset send status (current)**: `PaymentsModule.send()` supports single-coin (legacy), multi-coin, NFT-only, and mixed coin+NFT transfers via the optional `additionalAssets: AdditionalAsset[]` field on `TransferRequest`, where `AdditionalAsset` is a discriminated union `{kind:'coin', coinId, amount} | {kind:'nft', tokenId}`. The protocol enforces NFT/coin disjointness — every source token belongs to exactly one class. NFT transfers are always whole-token (no split, no change); coin transfers may split. See `docs/API.md` for the type signature and `docs/INTEGRATION.md` for usage examples. The protocol is asset-kind agnostic at the discriminator level; future asset kinds extend the union (subject to forward-compat reject rule above). + +3. **For each token destined to the recipient**, build a `TransferTransaction` (SDK primitive): + - `sourceState`: token's current state. + - `recipient`: recipient's destination address. + - `salt`: fresh random. + - `recipientDataHash`: optional, per request. + - **Submit commitment** to the aggregator: + - **Conservative mode**: `await waitInclusionProof(...)` → attach proof to transaction. + - **Instant mode**: submit and **do not await proof** — transaction's `inclusionProof` stays `null`. + +4. **Construct UXF bundle**: `UxfPackage.create()` then `pkg.ingestAll(transferredTokens)`. The package's element pool will contain the dependency DAGs (genesis, all prior transactions with proofs, predicates, certs, nametag refs) plus the new transaction. In **conservative mode**, the new transaction's `inclusionProof` child resolves to a real `inclusion-proof` element with valid `authenticator` + `merkleTreePath` + `unicityCertificate`. In **instant mode**, the transaction's `inclusionProof` child is `null`. + +5. **Serialize**: `const carBytes = await pkg.toCar();`. + +6. **Choose delivery** (per §3.3.1): + - `delivery: { kind: 'auto', inlineCapBytes? }` (default; `inlineCapBytes` defaults to **16 KiB**) — if `carBytes.length <= inlineCapBytes` → `kind: 'uxf-car'`; else pin to IPFS via `IpfsHttpClient.pin(carBytes)` → CID → `kind: 'uxf-cid'`. + - `delivery: { kind: 'force-inline' }` — always `kind: 'uxf-car'`. If `carBytes.length` exceeds the relay-safe ceiling, abort with `INLINE_CAR_TOO_LARGE` before publishing. + - `delivery: { kind: 'force-cid' }` — always pin and use `kind: 'uxf-cid'`, regardless of size. + +7. **Compute `bundleCid`**: extract the CAR root CID via `extractCarRootCid(carBytes)`. This is the canonical bundle identity. + +8. **Build payload**: +```typescript +const payload: UxfTransferPayload = { + kind: deliveryKind, + version: '1.0', + mode: transferMode, + bundleCid, + tokenIds: transferredTokens.map(t => t.genesisTokenId), + memo, + sender: { transportPubkey, nametag }, + ...(deliveryKind === 'uxf-car' ? { carBase64: base64(carBytes) } : {}), +}; +``` + +9. **Persist outbox entry** (BEFORE send, see §7). + +10. **Send**: `await transport.sendTokenTransfer(recipientPubkey, payload)`. On success, mark outbox `delivered`. On failure, mark `failed` and schedule retry. + +11. **Apply local state update**: + - **Conservative mode**: the sender's source token is updated to its new state (sender no longer owns it).

From §5.3 onward the disposition flow is identical (only §5.2 bundle-level checks are skipped, since there is no CAR / no bundleCid). + +### 4.5 Outbox tracking (see §7 for schema) + +The outbox is **bundle-grained** for UXF modes (one entry per UXF bundle, covering N tokens) — not per-token as in the legacy code. This matches PROFILE-ARCHITECTURE.md §10.12. For TXF mode the outbox falls back to one entry per token. + +The outbox's primary purpose is to guarantee **eventual delivery** despite intermittent network connectivity, app crashes, and infrastructure failures. Every transfer attempt is journaled before the Nostr publish; the journal is the source of truth for retry, finalization, and recovery. + +In **conservative mode**, the outbox entry's lifecycle is short: created at step 6, marked `delivered` at step 8, optionally garbage-collected immediately or retained for a configurable window for delivery acknowledgments. + +In **instant mode**, the outbox entry persists until finalization completes for **every** transaction the sender contributed to the chain (typically 1, but K if the sender forwarded a chain-mode token). It carries `outstandingRequestIds` and `completedRequestIds` so the async finalizer knows which proofs to fetch (per §6.1 error model). Sustained `PATH_NOT_INCLUDED` across the polling window is treated as terminal hard-fail; transient `PATH_NOT_INCLUDED` (a single snapshot before anchor) just means "keep polling." + +In **TXF mode**, the outbox entry is per-token and short-lived (same lifecycle as conservative-UXF, but with `deliveryMethod: 'txf-legacy'` and `bundleCid: 'txf-' + tokenId`). Instant-TXF entries follow the instant-UXF lifecycle but at per-token granularity. + +--- + +## 5. Recipient Flow + +### 5.0 Concurrency model — N parallel bundle workers + +Incoming bundles are processed by a **pool of parallel workers** (default `MAX_INGEST_WORKERS = 16`, configurable). When a Nostr `TOKEN_TRANSFER` event arrives, it is enqueued on a bounded ingest queue (default 256 entries) and dispatched to the next free worker. + +**Why parallelism is required**: a single rogue incoming bundle (e.g., one with a chain-mode token requiring K=64 unfinalized-tx finalization queue, or a `uxf-cid` bundle whose IPFS fetch is slow) would otherwise serialize behind every other legitimate bundle. With N workers, slow bundles consume a single worker each; the other N-1 continue serving fresh arrivals. This is a **DoS defense** against an attacker who deliberately crafts long-running bundles. + +**Worker isolation**: +- Each worker runs §5.1–§5.3 for its assigned bundle independently. Per-tokenId mutexes (§5.5 step 9) coordinate workers when two bundles target the same `tokenId`; otherwise workers proceed in parallel. +- Bundle-level errors (CAR parse failures, gateway timeouts) terminate the worker's processing of that bundle without affecting others. The worker returns to the dispatcher to pick up the next queued bundle. +- The ingest queue itself is bounded: if all `MAX_INGEST_QUEUE_SIZE` (default 256) slots are occupied, new arrivals are dropped with `INGEST_QUEUE_FULL` and the sender's outbox eventually times out (`failed-transient`). This is a hard back-pressure signal — the recipient cannot keep up — and a configurable monitoring metric. + +**Per-worker resource caps** (each worker enforces independently): +- §3.3.1 32 MiB fetched-CAR cap. +- §5.2 #3 chain-depth cap. +- §5.2 #4 unclaimed-roots cap. +- §5.5 finalization queue depth (capped per-tokenId, not per-worker). + +**Bundle-internal token parallelism**: within one bundle, all token-roots are processed by the SAME worker sequentially (no inner parallelism). This keeps per-bundle ordering consistent for §5.6 idempotency invariants. Cross-bundle parallelism is the protection against rogue inputs. + +### 5.1 Bundle acquisition + +Trigger: Nostr TOKEN_TRANSFER event arrives at `transport.handleTokenTransfer(...)`. Decrypted content parses to a `UxfTransferPayload`. + +``` +Recipient IPFS (if CID delivery) + │ │ + │ Nostr event arrives │ + │ │ + │ decrypt → payload │ + │ │ + │ if kind === 'uxf-cid': │ + │ fetch CAR via verified gateway pipeline ───────────▶│ + │ ◀─ CAR bytes (verified hash) ───────────────────────┤ + │ else (kind === 'uxf-car'): │ + │ carBytes = base64Decode(payload.carBase64) │ + │ │ + │ verify CAR root CID === payload.bundleCid │ + │ │ + │ pkg = UxfPackage.fromCar(carBytes) │ + │ │ +``` + +**Replay handling**: re-processing the same `bundleCid` is **idempotent**, not a correctness issue. A token is identified by its immutable `token.id`; the local pool can only ever hold one canonical copy per id, updated monotonically with the longest valid chain of finalized transactions. Re-processing wastes compute but cannot introduce duplicates, conflicts, or inconsistencies. The recipient maintains a bounded LRU set of recently-processed `bundleCid` values (default 256) **only as an optimization** to skip the redundant work; eviction from the LRU is harmless. + +### 5.2 Bundle verification + +Before per-token disposition, the recipient performs **bundle-level checks**. Cryptographic verification of individual transactions and proofs is at §5.3 [C], NOT here — bundle-level checks are structural only. + +1. **`pkg.verify()`** — UXF DAG integrity. The package verifier at `uxf/verify.ts` (WU-09) covers: + - Per-block multihash (every block in the CAR has its declared CID). + - Single-root CAR — `roots.length === 1` (multi-root CARs MUST be rejected per Wave G.5). + - Root CID match — `roots[0] === payload.bundleCid` (sender lying about which CID their CAR represents → reject the entire bundle). + - Type tag validity (every element has a known type). + - Hash-match on all element references. + - Cycle-free DAG (no element references itself transitively). + - Depth cap (default 4096) and pool size cap (default 1M elements) — DoS bounds. + Crypto checks (signatures, proofs) are NOT performed at this stage. +2. **Token ID claim consistency** — `payload.tokenIds` is advisory. The recipient MUST process every token-root element in the pool (subset, equal, or superset of `tokenIds`). Token-roots not in `tokenIds` are still subject to §5.3 ownership filtering at [B] — they are not "smuggled in" because [B] rejects anything whose current state doesn't bind to us. +3. **Chain-depth cap (per-token, with smuggling defense)** — apply `MAX_CHAIN_DEPTH` (default 64 unfinalized txs) per-token, with the following two-tier rule to prevent griefing-via-smuggled-roots: + - For every token-root in `payload.tokenIds` (the sender's claim): if depth > MAX_CHAIN_DEPTH, **reject the entire bundle** with `BUNDLE_REJECTED:chain-depth-exceeded`. The sender claimed it; the sender is responsible. + - For every token-root in the pool but NOT in `payload.tokenIds` (smuggled): if depth > MAX_CHAIN_DEPTH, **silently drop that token-root** from processing. The legitimate claimed tokens are still processed normally. This prevents an attacker from griefing a legitimate transfer by attaching a deep unclaimed root. + + Post-merge depth: if a `[D-merge]` operation produces a union token whose unfinalized-tx count exceeds MAX_CHAIN_DEPTH (because the local pool extended the chain beyond the cap), the merge proceeds but the resulting token's `manifest.status` is `pending` and a warning is logged — we trust our own pool's prior state. Only INCOMING bundles' fresh chains are capped. + +4. **Smuggled-roots count cap (`_audit` DoS defense)** — count only DAG elements with type-tag `token-root` (or any future root-equivalent type-tag — see fail-closed rule below) that are NOT in `payload.tokenIds`. Sub-DAG dependencies (predicates, prior-state references, transactions, inclusion proofs, certificates) are NOT counted — they have different type-tags. Precise formula: + ``` + const ROOT_EQUIVALENT_TYPES = new Set(['token-root']); // extend in lockstep with schema evolution + unclaimedRoots = pool.elements.filter(e => + ROOT_EQUIVALENT_TYPES.has(e.type) && !payload.tokenIds.includes(e.tokenId) + ).length; + ``` + If `unclaimedRoots > MAX_UNCLAIMED_ROOTS` (default 16), reject the entire bundle with `BUNDLE_REJECTED:too-many-unclaimed-roots`. The honest case has zero or a few unclaimed roots (sub-DAG dependencies are NOT token-roots — they're sub-elements). Without this cap, an attacker shipping 10K depth-1 unowned roots fills the recipient's `_audit` collection unboundedly via NOT_OUR_CURRENT_STATE dispositions. + + **Forward-compat (fail-closed)**: if the recipient encounters a top-level DAG element with a type-tag NOT recognized by its current implementation, it MUST log a warning AND count that element toward `MAX_UNCLAIMED_ROOTS` (treat as a potentially-smuggled root by default). Spec extensions adding new root-equivalent type-tags MUST update `ROOT_EQUIVALENT_TYPES` in lockstep across implementations to avoid breaking honest senders. + +If any other bundle-level check fails, the entire bundle is rejected with a typed `BUNDLE_REJECTED` error; nothing is imported. This is logged and surfaced as a `transfer:rejected` event. + +### 5.3 Per-token disposition — THE DECISION MATRIX + +For each `tokenId` in `payload.tokenIds` AND for every other token-root element actually present in the bundle's pool (see §3.1 — `tokenIds` is *advisory*; the recipient processes every token-root element and filters by ownership at [B]), the recipient walks the following decision tree. Each branch leads to a specific `disposition` outcome with a specific storage action. + +The matrix gates on **current-state ownership**, not genesis ownership: a token we receive via transfer was, by definition, originally minted to someone else, and that's perfectly normal.

This is mandatory for forensic traceability — it is set on the manifest entry whether the entry is being created fresh OR an existing entry is being updated by promotion. + +**Manifest metadata preservation across §5.3 [D] merges (normative)**: when §5.3 [D] resolves a conflict between two manifest entries for the same `tokenId` (whether via union-merge or CONFLICTING tie-break), the following metadata fields are preserved on the post-merge entry by **set-OR / max-merge** semantics regardless of which side "wins" the chain merge: +- `audit_promoted_from` — type widened to `auditKey[] | undefined` (an array of audit keys, or unset). On merge, take the union of both sides' arrays (deduplicated and lex-sorted) — divergent values reflect legitimate cross-replica audit history (e.g., the same `tokenId` was promoted from different audit entries on different devices); both records are preserved for forensic traceability. Implementations writing this field for the first time MUST use the array form (single-element array if only one promotion). +- `splitParent` — preserved if either side has it set; if both have it set with different values, that's a defect (a token cannot have two different parents); log warning and use the lexicographically-smaller value. +- `conflictingHeads[]` — union of both sides' lists, deduplicated. +- `lamport` — max of both sides (per §7.1 invariants). + +Other manifest fields (chain content, current state, status) follow the normal [D] resolution rules. Future spec extensions adding new metadata fields MUST classify each new field as either "preserved" (set-OR / max-merge) or "chain-content" (resolved per [D]). + +**Retention**: +- `_invalid`: indefinite by default; user can manually `cleanupInventory()` to clear. +- `_audit`: indefinite by default. Even after promotion, the original audit record is retained. + +### 5.5 Per-token finalization (chain-mode landing path) + +When a `PENDING` token enters the pool, **one entry per unfinalized transaction in the chain** is added to a per-address **finalization queue**. A token with K unfinalized transactions yields K queue entries; the token transitions from `pending → valid` only when all K are resolved (or it transitions to `invalid` if any one hard-fails — see step 5). + +**Chain depth bound (DoS defense)**: the recipient MUST reject bundles whose tokens have more than `MAX_CHAIN_DEPTH` unfinalized transactions in any single token's history (default **64**, configurable). Bundles exceeding the limit raise `BUNDLE_REJECTED:chain-depth-exceeded` at §5.2 — before any finalization queue is populated. + +```typescript +interface FinalizationQueueEntry { + tokenId: string; + bundleCid: string; // for cross-reference + txIndex: number; // position in token.transactions[]; 0 = genesis-adjacent oldest unfinalized + commitmentRequestId: string; // computed locally from (signedTx, sourceState) + signedTransferTxBytes?: Uint8Array; // present iff this hop's tx came from the incoming bundle; + // resolution falls back to the in-pool token by + // (tokenId, txIndex) if absent + submittedAt: number; // wall-clock time of first successful submit; + // initialized to createdAt at queue-creation; + // updated to the actual submit time on the + // first SUCCESS / REQUEST_ID_EXISTS response. + // pollingDeadline (§5.5 step 6) MUST NOT fire + // for entries with submittedAt === createdAt + // (no submit yet). + retryCount: number; + source: 'sent' | 'received'; // sender's outbox vs recipient's queue +} +``` + +The finalization worker (see §6) processes each entry. For each pending tx: + +1. Resolve `signedTransferTxBytes`: prefer the queue-entry field, fall back to the in-pool token at `(tokenId, txIndex)`. If neither has it, mark the queue entry `STRUCTURAL_INVALID` (reason='structural') and remove. The token transitions to `invalid`. +2. Compute `commitmentRequestId` locally from `(signedTx, sourceState)`. This MUST match the queue entry's stored value (defensive consistency check). +3. **Submit the commitment** to the aggregator (if not previously submitted by this worker). The submit endpoint returns one of (per `SubmitCommitmentResponse.js`): + - `SUCCESS` — commitment accepted; will be anchored in a forthcoming SMT snapshot. Proceed to step 4. + - `REQUEST_ID_EXISTS` — a commitment for this `requestId` already exists at the aggregator. Note that `requestId = SHA-256(publicKey ‖ stateHash.imprint)` per `RequestId.js` — it does NOT include `transactionHash`, so two different transitions over the same source state share the same `requestId`. `REQUEST_ID_EXISTS` therefore could mean EITHER (a) our own previous submit (idempotent retry, common case) OR (b) someone else's race-winning submit (race-loser case). Proceed to step 4 to resolve the ambiguity by polling — the proof retrieved there carries the canonical `transactionHash`, which we compare to ours to determine which case it is. + - `AUTHENTICATOR_VERIFICATION_FAILED` — the aggregator's crypto check rejected the authenticator. Local crypto passed, aggregator's didn't — `'belief-divergence'`. Mark the queue entry hard-failed. + - `REQUEST_ID_MISMATCH` — per the SDK docstring this means "Request identifier did not match the payload" — i.e., the client sent an inconsistent `(requestId, sourceState, transactionHash)` tuple. This is a CLIENT BUG, not a double-spend signal. Mark the queue entry hard-failed (reason='client-error') and emit an operator alert; the client computed the requestId incorrectly. + - Transient (network, 5xx): increment `submitRetryCount`; back off; retry. Bounded by `MAX_SUBMIT_RETRIES` (default 5). +4. **Poll `aggregator.getInclusionProof(commitmentRequestId)`** until a terminal status is observed: + - `verify() === OK` — proof is anchored. **Now compare the returned proof's `transactionHash` to our local `transactionHash`** (the one we just submitted or are tracking): + - **Match**: the anchored commitment is ours. Idempotent success. Proceed to step 5. + - **Mismatch**: the anchored commitment is someone else's — a race-winner submitted a different transition over the same source state before us. We are the race-loser. Mark the queue entry hard-failed (reason='race-lost'). The source token is genuinely valid (the race-winner's tx is on-chain); cascade does NOT fire (per §6.1.1 — race-lost is a special case where no children are invalidated). The local outbox entry transitions to `failed-permanent` with error code `OUTBOX_RACE_LOST`. + - `verify() === PATH_NOT_INCLUDED` — this is **a verifiable proof of non-existence at the polled snapshot** (the aggregator's BFT-signed merkle proof that no commitment is registered at this requestId in the current SMT root). This is **not a hard error**; it means "not yet anchored." Continue polling. Treat as terminal-rejected only after sustained PATH_NOT_INCLUDED across the polling window (see step 6). + - `verify() === PATH_INVALID` — the proof structure is malformed (truncated, mis-shaped). Likely faulty aggregator OR transport corruption. Increment `proofErrorCount`; retry up to `MAX_PROOF_ERROR_RETRIES` (default 3); then mark hard-failed (reason='proof-invalid'). + - `verify() === NOT_AUTHENTICATED` — the proof's validator signatures don't verify against the local trustBase. Emit `transfer:trustbase-warning` (most likely stale trustBase per §9.4.1; active forgery is out of scope). The SDK SHOULD attempt a trustBase refresh before retrying. Increment `proofErrorCount`; retry up to MAX_PROOF_ERROR_RETRIES; then mark hard-failed (reason='proof-invalid'). + - Transient (network, 5xx): back off; retry. Bounded by polling window. +5. **On proof retrieval** (`verify() === OK`): + - The proof element is content-hashed and added to the pool. + - The pending transaction's `inclusionProof` child is updated from `null` to the new proof's ContentHash. + - **Token identity does NOT change.** Per the audit in §2.1, `token.id` derives from `genesis.data.tokenId` and is immutable; `TransferTransactionData.calculateHash()` excludes the inclusion proof from the data hash. What DOES change is the *CBOR serialization* of the token (the proof bytes are now present), and therefore its *content-address (CID)*. + - **Manifest CID rewrite** (introduced in this protocol, Wave T.5 — NOT Wave H, which is unrelated null-hash canonicalization): the OrbitDB profile manifest entry for this `tokenId` is updated to point at the new CID. The previous (proof-less) CID is **tombstoned** in the manifest so older copies are not re-served from peer caches. + - Queue entry removed. + + **Crash-safe write order (NOT a single OrbitDB transaction — OrbitDB's keyvalue store has no multi-key atomicity primitive):** the four writes happen in a fixed order with each step idempotent on replay: + ``` + (1) pool write proof element ← content-addressed; re-write is no-op + (2) manifest CID rewrite ← idempotent; same input → same output + (3) tombstone insert ← additive; duplicate insert is no-op + (4) queue-entry removal LAST ← presence/absence is the durability anchor + ``` + If a crash interrupts between (1) and (4), the queue entry is still present on restart; the worker re-runs steps (1)-(4); each step is idempotent so the result converges. Implementation MUST follow the order; reordering breaks crash safety. + +6. **Polling-window terminal**: each queue entry has a `pollingDeadline = submittedAt + POLLING_WINDOW` (default 30 minutes), where `submittedAt` is the wall-clock time of the most recent successful submit (NOT the queue-entry `createdAt` — using `createdAt` would cause restart-resume of an already-old entry to hit the deadline after a single poll). The deadline is honored only if the worker has completed at least `MIN_POLL_ATTEMPTS` polls (default 5) within the window — this prevents a fast-clock-skew or aggressive-backoff path from declaring a hard-fail prematurely. If both conditions are met (deadline exceeded AND minimum polls done) AND every poll returned `PATH_NOT_INCLUDED` with no OK ever observed, the worker concludes the commitment was rejected (the aggregator never anchored it; no point in continuing). Mark the queue entry hard-failed (reason='oracle-rejected'). + + **Why a window, not a count**: PATH_NOT_INCLUDED is a *fresh proof of non-existence at a snapshot* — perfectly valid, just not the result we wanted. The aggregator's SLA guarantees commitments are anchored within bounded time (typically <1 BFT round = ~1s). A 30-minute sustained absence with at least 5 poll attempts is overwhelming evidence the commitment was dropped or rejected. + + **Backoff schedule**: poll at 30s, 60s, 120s, 240s, then every 5 min until deadline. With `POLLING_WINDOW = 30 min`, this gives roughly 8 poll attempts within the window — comfortably above `MIN_POLL_ATTEMPTS`. + + **Configuration validity rule (normative)**: the **cumulative** backoff schedule for the first MIN_POLL_ATTEMPTS polls MUST fit within POLLING_WINDOW: + ``` + cumulativeBackoff = sum(backoffIntervals[0..MIN_POLL_ATTEMPTS-1]) + REQUIRE cumulativeBackoff ≤ POLLING_WINDOW + ``` + For the default schedule (30s, 60s, 120s, 240s, 300s, 300s, …) and `MIN_POLL_ATTEMPTS=5`, cumulativeBackoff = 30+60+120+240+300 = **750s = 12.5 min**. So `POLLING_WINDOW` MUST be ≥ 12.5 min. The 30-min default leaves comfortable headroom. + + Implementations MUST validate this at startup and refuse to start if violated. As a hard safety net regardless of configuration, the worker SHALL also stop after `2 × POLLING_WINDOW` wall-clock time, declaring `oracle-rejected` even if MIN_POLL_ATTEMPTS was not reached — termination is guaranteed. + + **Transient errors do NOT count toward MIN_POLL_ATTEMPTS**: only polls that return a verifiable proof-status (OK, PATH_NOT_INCLUDED, PATH_INVALID, NOT_AUTHENTICATED) advance the attempt counter. Network errors / 5xx responses are retried but not counted — otherwise an aggressive transient-error condition could prematurely satisfy MIN_POLL_ATTEMPTS without actually observing aggregator state. + +7. **On hard-fail of any queue entry** (steps 3, 4, 6 terminal hard-fail paths): + - Mark the queue entry hard-failed with the canonical `DispositionReason`. + - **Short-circuit the chain**: per §6.1.1, ANY tx hard-fail invalidates the WHOLE token (the chain has a broken link). Immediately: + - Cancel polling for ALL other queue entries of this `tokenId` (no point continuing). + - Mark `manifest.status='invalid'` with the failing entry's reason. + - Move the token to `_invalid` collection. + - Cascade per §6.1.1 to locally-derived child tokens. + - Already-attached proofs from earlier-resolved queue entries are kept on the now-invalid token's CBOR (forensic value); the manifest's *primary* CID is tombstoned. + - Queue fully cleared for this `tokenId`. + +8. **On transient error (network, 5xx, etc.)**: increment retry count, back off, retry. Bounded by polling window for poll-side; bounded by `MAX_SUBMIT_RETRIES` for submit-side. + +9. **Queue-drain → status transition (per-tokenId locked)**: when a queue entry completes successfully (step 5), the worker MUST acquire a per-tokenId lock and within that lock check: "are there any remaining queue entries for this `tokenId` that are NOT in terminal-success?" + - If NO remaining + no hard-failed entries: re-run **[B]** (current-state predicate target — the merged chain may have changed who owns the token), then re-run **[D]** merge-check against any new pool arrivals that landed during finalization, then re-run **[E]** (oracle.isSpent on the now-finalized current state) to choose between `'valid'` and `'unspendable'`. The transition path: + - [B] fails (token's current state no longer binds to us) → move manifest entry to `_audit` (reason='not-our-state'). Underlying pool elements (the grafted proofs added by [D-merge]) are content-addressed and harmless if retained — leave them in pool; only the manifest entry is moved. + - [D] surfaces a CONFLICTING merge → `manifest.status='conflicting'` with `conflictingHeads[]`. + - [E] returns isSpent=true → move manifest entry to `_audit` (reason='off-record-spend'). Pool elements retained as above. + - All pass → `manifest.status='valid'`. Re-emit `transfer:incoming` with `confirmed: true`. + - This re-running is necessary because the token's chain may have grown via merge during finalization, AND the current-state predicate may have changed if the merge added a transfer-out we authored locally. + + **Per-tokenId lock requirement**: §5.3 ingest paths and §5.5 step 9 finalization paths share a per-tokenId mutex. This prevents a race where a queue-drain is finalizing a token to `valid` while a concurrent §5.3 ingest of a divergent bundle would have produced `CONFLICTING` — without the lock, two workers could both observe an intermediate state and reach contradictory final dispositions. Implementations MAY use OrbitDB-level optimistic concurrency (compare-and-swap on the manifest entry's content hash) or an in-process lock; the choice is implementation-defined but the exclusion property is normative. + + **Lock-vs-network-I/O hold rule**: re-running [E] involves `oracle.isSpent()` — a network round-trip that may take seconds under aggregator load. Holding the per-tokenId mutex during this RPC would serialize the entire per-token finalization queue behind one slow call. Implementations MUST follow ONE of: + - **CAS-based** (preferred): no lock is held; each transition is a compare-and-swap on the manifest entry's content hash. Conflicts surface as CAS failure → retry from the latest state. Works correctly across slow RPCs because no global lock is held. + - **Lock-with-RPC-release**: the worker acquires the lock, snapshots the relevant state, **releases the lock** before issuing `oracle.isSpent()`, then re-acquires the lock and verifies the manifest content hash is still what it snapshotted before applying the post-RPC state transition. If the hash changed (concurrent write), restart from the read step. + - **Lock-with-bounded-hold**: as a fallback, implementations using a strict in-process mutex MUST set `MAX_LOCK_HOLD_MS` (default 5s) and abort + retry if exceeded. Forbids unbounded lock-during-RPC. + + **Lock ordering for cascade (deadlock prevention + parent-flip protection)**: §6.1.1 cascade walks parent → children. To prevent AB-BA deadlocks with worker threads holding child locks while needing parent locks, the cascade rule is: + - The cascading worker acquires the **parent's** lock first, identifies the children, **releases the parent's lock**, then acquires each child's lock individually (in lexicographic order of `tokenId`) to apply the cascaded `parent-rejected` marker via compare-and-swap. + - **Parent-flip protection (mandatory)**: under each child's lock — and inside the CAS payload computation for CAS-based implementations — the cascade worker MUST re-read the parent's manifest entry and verify the parent is still in `_invalid` with `status='invalid'`. If the parent has flipped to `valid` (e.g., a concurrent `importInclusionProof()` override resolved the parent), the cascade for that child is aborted (no-op). This prevents a stale cascade from invalidating children whose parent is no longer rejected. + - Implementations using compare-and-swap on manifest content hashes (rather than explicit locks) avoid the deadlock concern entirely — each child write is atomic on its own manifest entry; conflicts surface as CAS failures and retry. The parent-flip protection still applies (re-read parent inside the CAS payload computation). + +**Tombstone retention**: tombstoned manifest CIDs are retained for `TOMBSTONE_RETENTION_DAYS` (default 30) after the canonical CID has been stable. After that, the tombstone is GC'd to prevent unbounded manifest growth in long-lived wallets. + +**Merge-path finalization (§2.3)**: when another UXF copy of the same token arrives carrying additional proofs, those proofs are grafted into the local pool via the Wave G.3 enrichment rules. Each grafted proof eliminates the corresponding queue entry without an aggregator round-trip — same atomic update pattern as step 5. + +### 5.6 Replay / duplicate / merge handling + +All of the following are **idempotent and convergent**; nothing requires special-casing beyond the §5.3 decision matrix: + +- **Same `bundleCid` arrives twice**: re-process is wasted compute (suppressed by the LRU optimization in §5.1) but cannot diverge from the first processing. +- **Same `bundleCid`, different outer-envelope fields claimed** (`mode`, `tokenIds`, `sender.nametag`): the outer envelope is NOT covered by `bundleCid`. Processing semantics depend ONLY on the bundle contents (proofs present, predicates resolvable, etc.); outer fields are advisory. `tokenIds` is treated as advisory — the recipient processes every token-root element in the pool, filtered by ownership at [B]. Do NOT trust `sender.nametag` for UI display unless re-resolved against the Nostr signing pubkey. +- **Same `tokenId` arrives in two bundles from different senders**: handled by `[D]` conflict check; `resolveTokenRoot` decides. Tie-break for genuinely-divergent chains: lex-min `bundleCid` wins primary. +- **Same `tokenId` arrives carrying additional proofs while a `PENDING` entry exists** (the chain-mode merge case): the new proofs are grafted into the existing entry via Wave G.3 enrichment. Queue entries for now-finalized txs are removed. If all unfinalized txs become finalized, the [E] re-run determines `valid`/`unspendable`. The token stays put — no rebuild — only its CID may change. +- **Two copies of the same `tokenId` arrive with different transaction sets**: if one chain's transaction set is a strict prefix of the other (i.e., one was forwarded again before some hops finalized, the other is the longer history), `resolveTokenRoot` selects the longer chain and grafts in any proofs the shorter chain carries. Proof grafting is monotonic — proofs accumulate, never delete. + +**Idempotency invariant (MUST)**: the disposition of a token MUST never regress. Specifically: +- A `valid`/`archived` token MUST NEVER transition back to `pending` on receive — replay of an older copy is a no-op for status. +- A `pending` token's queue entries can only be REMOVED (proof attached, hard-failed) — never re-added for the same tx index unless §5.5 step 9's re-run found a new merge that added the tx. +- An `invalid` token MUST NEVER transition out of `_invalid` — a later valid copy of the same `tokenId` is treated as `CONFLICTING` (and stored with the conflicting-heads list) but the existing invalid disposition is preserved for forensics. + +--- + +## 6. Asynchronous Finalization + +Both the **sender** (for instant-mode-sent tokens) and the **recipient** (for any pending tokens) run finalization workers. The two workers are independent — they do not coordinate — and the protocol is designed so they converge to the same valid local state without exchanging messages. + +A worker may need to resolve **multiple unfinalized transactions per token** (chain-mode tokens, §2.3). Both workers walk the entire transaction history, not just the latest tx. + +### 6.1 Sender-side finalization worker + +Trigger: outbox entry with `status: 'delivered-instant'` and one or more outstanding `commitmentRequestIds`. The list MAY contain entries for transactions the sender did not author (chain-mode forwards inherit a list of unfinalized inbound txs that the sender now also has an interest in resolving, since the token won't transition to `valid` locally until they're done). + +**Threat model**: the aggregator is **faulty, never hostile** (see §9.4 for the explicit threat-boundary). The worker's strategy is therefore: trust the local cryptographic checks, persist the belief that "if our checks pass, the commitment IS valid," and re-submit / re-poll until the aggregator agrees or a bounded budget is exhausted. + +**Error model** (canonical, per `@unicitylabs/state-transition-sdk`): + +Submit-side responses (`SubmitCommitmentStatus`). **Critical**: `requestId = SHA-256(publicKey ‖ stateHash.imprint)` per `RequestId.js` — does NOT include `transactionHash`. Two different transitions over the same source state have IDENTICAL `requestId`; race-lost detection therefore cannot use submit-side codes alone — it requires polling for the anchored proof and comparing `transactionHash`. + +| Response | Meaning | Worker action | +|---|---|---| +| `SUCCESS` | Commitment accepted; will be anchored shortly | Proceed to poll | +| `REQUEST_ID_EXISTS` | A commitment for this `requestId` already exists.

Concurrent polling reduces wall-clock latency for chain-mode tokens but should not flood a single aggregator endpoint. + +**Per-aggregator concurrency**: the worker MAY enforce a global cap on in-flight polls per aggregator endpoint (default 16) to prevent the worker itself from DoS-ing the aggregator under a wide chain-mode burst. + +#### 6.1.1 Cascade on hard-rejection + +When a queue entry hard-fails (retries exhausted), the failing token is marked invalid. **Cascade behavior depends on the token's class** (per §4.1 canonical asset model — class-disjoint coin vs NFT): + +**Coin-token splits** — split-cascade via `splitParent` reference: + +When a coin token was previously split via `TokenSplitBuilder` (which mints fresh `tokenId`s for the recipient + change outputs), the children carry a `splitParent: tokenId` reference on their manifest. If the split-parent's chain hard-fails, the children are derived from a non-existent parent state and are also invalid. The worker MUST: + +1. Identify all locally-stored tokens whose manifest has `splitParent === `. +2. Cascade `manifest.status = 'invalid'` (reason='parent-rejected') to each child. +3. Move each cascaded child to `_invalid` with reason='parent-rejected', `parentTokenId: `. +4. Emit `transfer:cascade-failed` for any outgoing bundles in the outbox that reference the cascaded children — best-effort notification to downstream recipients (delivery is informational; recipients will independently arrive at the same disposition via their own §5.3 [C](3) check when workers poll the aggregator for the failed tx). + +**NFT tokens** — NO splitParent cascade (NFTs are not splittable): + +NFT tokens (empty/null `coinData`) cannot be split — `TokenSplitBuilder` rejects empty-coinData inputs. NFT transfers are whole-token state-transitions: the recipient gets the SAME `tokenId` with new current state. There are no "child tokens" to cascade to. The cascade rule for NFTs is therefore: + +1. The failing NFT itself is marked `invalid` and moved to `_invalid` (reason='oracle-rejected' or 'race-lost' or whichever applies). +2. **Outbox-driven downstream notification**: every outbox entry that shipped this NFT to a recipient (in instant mode, before finalization) is examined. For each, emit `transfer:cascade-failed` with the recipient's pubkey and the NFT's tokenId. This is best-effort — downstream recipients independently arrive at the same `invalid` disposition via their own §5.3 [C](3) check when their workers resolve the failing predecessor tx. +3. **NO splitParent walk** — NFTs do not have `splitParent` set; the field is ignored for NFT-class tokens. + +**Race-lost special case** (per §6.1 step 4): + +When a token's queue entry hard-fails with reason=`'race-lost'` (race-winner's transaction is anchored, ours isn't), the cascade does NOT fire — the source token is genuinely valid (the race-winner's tx is on-chain), and the recipient never received our bundle. Only the outbox entry transitions to `failed-permanent`; the source token's local state is untouched. This is unique to race-lost; all other hard-fail reasons trigger the cascade per the rules above. + +Cascade is **monotonic** by default. A cascaded `invalid` disposition cannot be reversed automatically. **Operator-explicit reversal path** for the case where the aggregator later returns a valid proof for the parent's tx (which it shouldn't, given the threat model — but operationally this can happen if the aggregator was transiently faulty and the cascade fired prematurely): + +```typescript +// Reverse the parent's invalidation first via §6.3 importInclusionProof +// with allowInvalidOverride=true. THEN call: +function revalidateCascadedChildren(parentTokenId: string): RevalidationResult; + +interface RevalidationResult { + readonly checked: number; // children inspected + readonly revalidated: number; // moved from _invalid back to active pool + readonly stillInvalid: number; // still invalid for reasons OTHER than parent-rejected +} +``` + +`revalidateCascadedChildren()` scans `_invalid` for entries with reason='parent-rejected' AND `parentTokenId` matching the supplied id. For each such child: +- If the parent is now in active pool with `status='valid'`: re-run §5.3 [B]/[C]/[D]/[E] on the child. If it passes, move the child back to active pool with the appropriate disposition. +- If the parent is still invalid: leave the child in `_invalid`. +- If the child fails [B]/[C]/[E] for reasons unrelated to parent: leave it in `_invalid` with reason updated to the new disposition (e.g., 'off-record-spend' if isSpent=true now). + +**Transitive cascade reversal**: cascades can be transitive (A → B → C → D, with A's failure invalidating B, B's invalidation cascading to C, etc.). `revalidateCascadedChildren()` is **transitive by default**: when it successfully revalidates a child, it recursively calls itself on the revalidated child's `tokenId` to revalidate any grandchildren. Operators call the function once on the original parent; the SDK walks the dependency tree. + +**Cycle defense (defensive)**: token chains are append-only DAGs (parents are predecessors, children are successors), so cycles cannot arise from honest chain construction. However, `splitParent` is a manifest-side annotation that could in principle be corrupted. The implementation MUST maintain a visited set during transitive recursion and bound depth at `MAX_CHAIN_DEPTH` (default 64, matching §5.5 chain-depth bound). On detected cycle or depth-overrun, the recursion stops and returns the partial revalidation result with a `cycle-detected` warning. + +This is an explicit operator action; the SDK does not auto-cascade-reverse on parent override. + +**Cascade-risk warning to caller**: an instant-mode split issued from a still-pending parent inherits the parent's cascade risk. The SDK MUST surface this to the caller in two ways: +1. The `send()` result includes `splitParent: { tokenId, status: 'pending' | 'valid' }` whenever the result includes a freshly-minted child token. Callers can inspect `splitParent.status === 'pending'` and decide whether to gate their UX on parent finalization. +2. The SDK emits `transfer:cascade-risk-warning` events when a downstream send is composed from a still-pending parent: `{ childTokenId, parentTokenId, parentStatus }`. + +Optional gate: callers MAY pass `requireParentFinalized: true` to `send()`; the SDK will reject with `PARENT_NOT_FINALIZED` if any source token has unfinalized chain history. Default: `false` (instant splits are allowed). + +#### 6.1.2 Outbox terminal states + +- `finalized` — every proof attached cleanly. +- `failed-permanent` — any of: submit-side `AUTHENTICATOR_VERIFICATION_FAILED` (belief-divergence) or `REQUEST_ID_MISMATCH` (client-error), sustained `PATH_NOT_INCLUDED` past polling window (oracle-rejected), retry-exhausted `PATH_INVALID` / `NOT_AUTHENTICATED` (proof-invalid), or poll-side `OK` with mismatching transactionHash (race-lost via `OUTBOX_RACE_LOST`). Operator may inspect via `_invalid` records and decide whether to escalate. +- `failed-transient` — transient errors exhausted the retry budget. Worker stops; operator MAY trigger manual retry via `payments.retryFinalize(outboxEntryId)`. + +### 6.2 Recipient-side finalization worker + +Same logic as 6.1 but driven from the per-address finalization queue (§5.5) rather than the outbox. Each `tokenId` in the queue may have K entries (one per unfinalized tx); the token transitions `pending → valid` only when all K resolve to `OK`. + +The merge path (§5.5 last paragraph) provides an alternative: if a more-finalized UXF copy of the same token arrives via Nostr / IPFS / backup-import, its proofs are grafted into the local pool, eliminating the corresponding queue entries without an aggregator round-trip. + +### 6.3 Convergence guarantees + +**Claim**: an instant-mode transfer that succeeds at the aggregator will eventually transition to `valid` on BOTH sender and recipient, regardless of whether the chain has 1 or K unfinalized transactions and regardless of the order in which proofs become available. + +**Two distinct kinds of equality** matter for convergence: + +1. **Token identity (`token.id`) equality** — by design, immutable: derived from `genesis.data.tokenId`, never changes across proof attachment. Both sides agree on `token.id` from the moment the bundle is opened. +2. **Token CID equality** — the IPFS content-address of the serialized token. This DOES change when proofs are attached (the CBOR encoding gains the proof bytes). Both sides converge to the SAME final CID *only when they have attached the same set of proofs*. + +**Proof sketch**: + +**Crucial invariant about unicity proofs (per the underlying state-transition protocol)**: +- For a given `requestId`, the aggregator NEVER signs proofs for two DIFFERENT values (different `transactionHash` + `authenticator`). Single-spend at the SMT level guarantees this — if a different value were committed, it would be the canonical one and the original would be unanchored. +- For a given `requestId` AND value (transactionHash + authenticator), MULTIPLE proofs may legitimately exist over time. The SMT grows with every BFT round; an old proof's merkle path is valid against the OLDER root, but a fresher proof against the NEWER root has identical leaf data and identical (transactionHash, authenticator) — only the witness path and the unicity certificate differ. +- This means: same-value proofs at successive aggregator snapshots are NORMAL and EXPECTED. Implementations MUST handle "the proof I already have" being superseded by a more-recent equivalent. + +**Canonicalization rule (most-recent proof wins)**: when two proofs exist locally for the same `requestId` with the same (transactionHash, authenticator), the protocol prefers the **most recent** — i.e., the proof whose `unicityCertificate` was issued in the latest BFT round. Recency is determined by: +1. The `unicityCertificate` carries a BFT round number (or equivalently, a timestamp/sequence). Higher round = more recent. +2. If round numbers are unavailable in the certificate format, use the proof's CID with a "first-observed-locally" timestamp recorded in the manifest's `lastProofRefreshAt` field. + +If the local manifest already has a proof for a queue entry's requestId, and a fresh poll returns a NEWER proof for the same value, the worker: +- Verifies the new proof against trustBase. +- Replaces the old proof element in the pool with the new one. +- Updates the manifest CID rewrite (per §5.5 step 5) — the token's CBOR encoding now embeds the newer proof, so its CID changes; tombstone the previous CID. +- Does NOT alter the queue entry's status (the entry was already in `completedRequestIds`); this is purely a maintenance operation. + +**Forbidden** (would indicate aggregator failure): observing two proofs for the same requestId with DIFFERENT values (different transactionHash). If this ever happens, emit `transfer:security-alert` immediately — the single-spend invariant has been violated at the aggregator. The protocol does NOT auto-recover; an operator must investigate. (This is the only path that emits `transfer:security-alert` in the routine flow; per §9.4.1, all other suspect events emit `transfer:trustbase-warning` first.) + +**Convergence sketch**: +1. For each requestId, both finalizers eventually retrieve some valid proof. The proofs are over IDENTICAL values (transactionHash, authenticator) — by aggregator invariant. +2. If both finalizers retrieve at the same BFT round, the proofs are byte-identical; trivially convergent. +3. If the finalizers retrieve at different rounds, the proofs differ in witness path + certificate but agree on value. After both run §12.3.1 profile-pointer rescan and exchange manifests, the most-recent-proof rule selects the same canonical proof on both sides; manifests converge to the same CID for the token. +2. Both finalizers fetch each pending proof independently. Both attach byte-identical `inclusion-proof` elements to byte-identical transaction objects. +3. The transaction's data hash (`TransferTransactionData.calculateHash()`) is unchanged — proofs are not in its preimage. So the per-tx CID changes (the encoded form is different) but the `transactionHash` referenced *by* the inclusion proof remains the same. +4. The token's `id` is unchanged throughout. The token's CID — the content-address of its CBOR encoding — converges once both sides have the same proof set attached. +5. Both manifests update `tokenId → newCid` and set `status='valid'` once all unfinalized txs in the chain are resolved AND the [E] re-run confirms `oracle.isSpent === false`. +6. Subsequent `pkg.merge` between the two pools dedupes via Wave G.3 (identical content → identical CID); the merge is a no-op. + +**Failure mode (commitment never anchored)**: both finalizers see the same eventual signal (per §6.1 error model — sustained `PATH_NOT_INCLUDED` over the polling window resolves to reason='oracle-rejected'; or post-poll `OK`-with-mismatching-transactionHash resolves to reason='race-lost'). Both mark the token's queue entry `failed-permanent` per §6.1. The dispositions converge across replicas — both reach the same outcome (oracle-rejected, race-lost, or invalid via §6.1.1 cascade) given the same canonical aggregator state. + +**Asymmetric-knowledge mode (one side has more proofs than the other, no network)**: as long as the more-knowledgeable copy reaches the lagging side via any channel (a second Nostr delivery, a backup import, an IPFS pull) the merge is monotonic — proofs accumulate. Convergence does not require both sides to ever reach the aggregator. + +**Stuck-PENDING escape hatch**: if neither side reaches the aggregator AND they don't reach each other, the token is `PENDING` indefinitely. The SDK exposes: + +```typescript +function importInclusionProof( + tokenId: string, + proofBytes: Uint8Array, + options?: { allowInvalidOverride?: boolean } +): ImportProofResult; + +type ImportProofResult = + | { ok: true; transition: 'pending-still' | 'pending→valid' | 'pending→unspendable' } + | { ok: false; reason: + | 'no-such-token' // tokenId not in our pool, _invalid, or _audit + | 'tokenId-already-valid' // token is already manifest.status='valid'; idempotent no-op + | 'tokenId-in-invalid' // token is in _invalid; requires allowInvalidOverride + | 'proof-trustbase-failed' // proof.verify(trustBase) returned not-OK + | 'proof-not-anchored' // verify returned PATH_NOT_INCLUDED — proof shows non-existence + | 'requestid-mismatch' // proof's requestId doesn't match any outstanding queue entry + }; +``` + +**Default values**: `allowInvalidOverride` defaults to `false` if omitted. The override is an explicit operator action that breaches the §5.6 monotonicity invariant ("invalid → ?" is normally forbidden); callers MUST set it to `true` deliberately. Silently defaulting to `true` would allow accidental invariant violations. + +Behavior cases: +1. **tokenId not in pool / _invalid / _audit**: `{ ok: false, reason: 'no-such-token' }`. The SDK has no context for the proof. +2. **tokenId is `valid`**: `{ ok: true, transition: 'pending-still' }` — idempotent no-op. The proof was already attached. +3. **tokenId is `pending`, proof matches an outstanding queue entry's requestId**: validates against trustBase; if `verify() === OK`, grafts in per §5.5 step 5. May trigger queue drain → `pending → valid` (or `pending → unspendable` if isSpent re-check returns true). +4a. **tokenId is `pending`, proof matches a `completedRequestIds` entry** (already resolved): `{ ok: true, transition: 'pending-still' }` — idempotent no-op. The proof was already attached previously. +4b. **tokenId is `pending`, proof doesn't match any outstanding OR completed requestId**: `{ ok: false, reason: 'requestid-mismatch' }`. The proof is for a different transition. +5. **tokenId is in `_invalid` AND `allowInvalidOverride === true` AND the token had EXACTLY ONE hard-failed queue entry, matching the proof**: validates the proof; if OK, MOVES the token from `_invalid` back to active pool with `manifest.status='valid'` (the prior invalidation was wrong — the original aggregator response was faulty, the proof now demonstrates the correct anchored state). This is the explicit operator override of the §5.6 monotonicity invariant. +6. **tokenId is in `_invalid` AND `allowInvalidOverride === true` AND the token had MULTIPLE hard-failed queue entries** (chain-mode case): validates the proof; if OK, MOVES the token from `_invalid` back to active pool with `manifest.status='pending'` and re-queues the K-1 remaining entries as fresh queue entries (each with `submittedAt = now`, fresh `pollingDeadline`). The token returns to the normal finalization path. The operator must then either wait for those K-1 entries to resolve OR import each of their proofs separately. + + > **Important — re-queue is usually futile without the additional proofs**: the K-1 entries previously hard-failed because the aggregator never anchored their commitments (sustained PATH_NOT_INCLUDED) or because they lost a race (poll-side OK with mismatching transactionHash). Nothing about re-queueing causes the aggregator to behave differently — those entries will hard-fail again after one polling window, re-cascading the token to `_invalid`. Operators SHOULD provide proofs for ALL K-1 remaining entries via repeated `importInclusionProof()` calls (one per requestId) BEFORE expecting the token to converge to `valid`. A future `bulkImportInclusionProofs(tokenId, proofs[])` API MAY consolidate this (deferred — §12.2). +7. **tokenId is in `_invalid` AND no override flag**: `{ ok: false, reason: 'tokenId-in-invalid' }`. +8. **Proof verify returns `PATH_NOT_INCLUDED`**: `{ ok: false, reason: 'proof-not-anchored' }`. The proof is a valid proof of NON-existence; it doesn't help unstick. +9. **Proof verify returns `PATH_INVALID` / `NOT_AUTHENTICATED`**: `{ ok: false, reason: 'proof-trustbase-failed' }`. + +UI surfaces stuck-pending tokens after a configurable timeout (default 7 days) so the operator can paste in a proof obtained out-of-band. The 7-day timer DOES reset on any successful state transition (e.g., partial graft of K-1 of K queue entries restarts the clock for the remaining one). + +**Time-horizon reference table** (clarifies the multiple timers in this spec): + +| Timer | Default | Scope | Purpose | +|---|---|---|---| +| `MAX_SUBMIT_RETRIES` | 5 | Per-requestId submit-side | Bounded transient retries on submit | +| `MAX_PROOF_ERROR_RETRIES` | 3 | Per-requestId poll-side | Bounded retries on PATH_INVALID / NOT_AUTHENTICATED | +| `POLLING_WINDOW` | 30 min | Per-requestId poll-side | Sustained PATH_NOT_INCLUDED → terminal | +| `MIN_POLL_ATTEMPTS` | 5 | Per-requestId poll-side | Floor before deadline can fire | +| Outbox `retryDeadline` | 24 hours | Per-outbox-entry | Total transient-retry budget for delivery | +| UI stuck-pending surface | 7 days | Per-token | Surface to operator for manual proof import — applies ONLY to tokens still in `pending` status, NOT to tokens already in `_invalid` (those are protocol-declared terminal failures, not stuck) | +| Cascade-stuck surface | n/a (manual) | Per-token | A child token cascaded to `_invalid` with reason='parent-rejected' is NOT surfaced by the stuck-pending timer. The operator must invoke `revalidateCascadedChildren(parentTokenId)` after using `importInclusionProof` to override the parent. The SDK SHOULD provide a UI affordance "X cascaded children — revalidate?" whenever a parent is overridden. | + +A token can transition to `_invalid` via §6.1 within ~30 min of submit (if the aggregator's response is decisive), well before the 7-day stuck-pending UI fires. The two timers serve different semantic states: protocol-defined failure (terminal) vs. UI-surfaced limbo (still finalizable in principle). + +**Crash recovery**: outbox + finalization queue are persisted to OrbitDB; both survive process restart. After restart, the worker resumes polling. The atomic-update rule in §5.5 step 5 ensures no double-attach. Pre-publish persistence ordering: the OrbitDB write that sets `status: 'sending'` (or `'delivered-instant'`) MUST be committed before the Nostr publish is dispatched; if the crash lands between OrbitDB commit and Nostr publish, the worker re-publishes on restart (idempotent for the recipient — bundleCid is content-addressed; same input → same bundle). + +--- + +## 7.

Loses to active states on merge — if any replica is still progressing, that progress should not be overwritten by a transient failure on a different replica. +- **Hard-terminal** (no further worker progress without operator action): `expired`, `finalized`, `failed-permanent`. Wins against both active and soft-terminal. + +The `finalized` over `failed-permanent` ordering rule still applies among hard-terminals — but see §7.1 for the override interaction. + +### 7.1 OrbitDB CRDT invariants + +The outbox is persisted in OrbitDB. OrbitDB has eventual-consistency (CRDT) semantics across replicas (e.g., desktop wallet + browser wallet for the same identity). The keyvalue store has only per-key `put`/`get`/`del` primitives; cross-key atomicity is NOT provided by the adapter (`profile/orbitdb-adapter.ts:331-378`). + +**Lamport clock invariants (normative)**: +- `lamport: number` is a Lamport logical clock per `UxfTransferOutboxEntry`. It is NOT a wall-clock timestamp and NOT a per-replica monotonic counter — those are not comparable across replicas. +- On every local write to an entry, the writer reads the current `lamport` value AND the maximum `lamport` of any concurrently-observed remote replica's view of the same entry, then writes `lamport := max(local, observedRemotes) + 1`. +- On merge, `lamport := max(replicaA.lamport, replicaB.lamport)` (this is the natural CRDT max-merge consistent with the writer rule). +- Implementations that fail to follow this rule will see non-deterministic merge outcomes — the override path in §7.0 in particular depends on the override's Lamport being strictly greater than the pre-override `failed-permanent`'s Lamport. + +**Override stickiness**: when `payments.importInclusionProof()` (§6.3) transitions `failed-permanent → finalizing`, the writer also sets a sticky boolean flag `overrideApplied: true` on the entry. This flag survives all subsequent merges (set-OR semantics: any replica having `overrideApplied === true` causes the merged entry to have it). When `overrideApplied === true`, the active-state's `finalizing` wins against any replica's `failed-permanent` regardless of Lamport — this prevents the override being undone by a stale replica with a higher Lamport for unrelated reasons. + +**`everFinalizing` sticky flag (steelman crit #12)**: a second sticky CRDT-stable boolean — `everFinalizing: true` — is set whenever any replica has at one point passed through `status === 'finalizing'`. The writer stamps it on every write whose status is `finalizing`; the merger carries it forward (set-OR) on every fold. Required for CRDT associativity of the override arc: without it, the multiset `{finalizing-no-flag, failed-permanent-no-flag, failed-permanent-overrideApplied}` was non-associative in 3-way merges (an intermediate hard-terminal fold could erase the `finalizing` status before the override-flag bearing replica was folded in, suppressing the revival arc). With the flag, the override arc fires whenever the merged multiset has historically contained `finalizing` AND any side carries `overrideApplied: true` — even when neither current replica has `status === 'finalizing'`. This restores `merge(merge(a, b), c) == merge(a, merge(b, c))` for every reachable multiset. The flag's set-OR semantics matches the gossip-fold model: every replica that ever observes the flag re-emits it forever, so the override revival arc is independent of fold order. + +**Dual-override case** (informational): if both replicas independently apply `importInclusionProof()` with possibly different proofs, both end up in `finalizing` with `overrideApplied = true`. The status partition rule "both active" applies → lattice + Lamport tie-break. The merged `outstandingRequestIds` and `completedRequestIds` sets reflect both override paths' updates per the set-merge rules. If the imported proofs are valid for the same requestId, they are byte-identical (per §6.3 idempotency canonicalization) and the merge is harmless. If they disagree (different requestIds, e.g., different unfinalized txs in the chain), the §5.5 finalization queue handles the divergence by resolving each requestId against aggregator-anchored truth — the protocol converges naturally. + +**Conflict resolution rules under replica merge:** + +1. **Status field — three-way partition with override-aware tie-break:** + - If both replicas are **hard-terminal**: prefer `finalized` over any other; among `failed-permanent | expired`, prefer `failed-permanent`. Tie-break by Lamport timestamp (higher wins — the more-recent decision sticks). EXCEPTION (override case): if one replica is in `finalizing` (active) with `overrideApplied === true`, that replica wins regardless of Lamport against the other replica's `failed-permanent`. The override flag is sticky and survives merge (set-OR), so a wallet that has performed `importInclusionProof()` keeps the override even if a remote replica's Lamport runs ahead for unrelated reasons. + - If both are **active**: prefer the more-advanced state per the lattice `packaging < pinned < sending < {delivered, delivered-instant} < finalizing`. Among `delivered` and `delivered-instant` (siblings — different finalization modes for the same send), tie-break by Lamport timestamp; the higher Lamport wins because the more-recently-decided mode reflects the actual outcome. + - If one is **active** and the other is **soft-terminal** (`failed-transient`): active wins. A replica still progressing should not be overwritten by another replica's transient failure. + - If one is **active** and the other is **hard-terminal**: hard-terminal wins (subject to the override exception above). + - If one is **soft-terminal** and the other is **hard-terminal**: hard-terminal wins. + - If both are **soft-terminal** (`failed-transient`): higher Lamport wins (more-recent retry attempt). +2. **`outstandingRequestIds` set:** merge as `union(replica_A_outstanding, replica_B_outstanding) - union(replica_A_completed, replica_B_completed)`. This prevents finalized requestIds from being re-added by a stale replica. Set-union alone would re-trigger submissions. +3. **`completedRequestIds` set:** merge as straight `union(replica_A_completed, replica_B_completed)` — completed never un-completes. +4. **`submitRetryCount`, `proofErrorCount`:** max-merge (CRDT G-counter shape). +5. **`error` field:** strictly-associative CRDT join in the lattice `undefined < string`: + - Both `undefined` → `undefined`. + - Exactly one defined → the defined string (error stickiness). + - Both defined → **lex-min of the error string** (deterministic tie-break). + + **Rationale.** Earlier drafts of this rule used "more-advanced status wins; equal-status → earlier Lamport wins." That formulation is not associative under 3-way merges: pairwise-merged Lamports become `max(a, b)`, which obliterates the original "earlier" timestamp and produces different `merge(merge(a,b),c)` vs `merge(a,merge(b,c))` outcomes for the surviving error string. The status-takes-error variant has the same problem when intermediate winners differ across merge groupings. The lex-min rule is purely a function of the multiset `{a.error, b.error}` and is therefore commutative AND associative by construction. It honors the spec's INTENT ("first-decided error is preserved" — usually only one replica records an error per cascade) with one narrow trade-off: when two replicas independently set distinct error strings, the lex-min string survives instead of the temporally-earlier one. This is the standard CRDT lattice resolution. + + Empty string `""` is treated as "present" (a defined value), not coalesced to `undefined` — writers MUST never persist `""` if they mean "no error". +6. **`lamport` timestamp:** max-merge. + +**Spend protection** comes from the aggregator's `requestId` invariant. A replica rollback that re-creates an outbox entry for an already-transferred source state will hit `REQUEST_ID_EXISTS` at the next aggregator submission; the worker then polls and discovers the race-loser case (proof's `transactionHash` ≠ local) and marks the entry `failed-permanent` with reason='race-lost'. The outbox correctly records the failed re-attempt; the source token's on-chain state is untouched. + +**Two-replica race on `send()` from same source state**: replicas A and B simultaneously fire `send()` from the same source token. Each generates a fresh-random salt → different `transactionHash` but **identical `requestId`** (since `requestId = SHA-256(publicKey ‖ stateHash.imprint)` excludes `transactionHash`). Both submit to the aggregator. First-arriving wins `SUCCESS`; the second's submit returns `REQUEST_ID_EXISTS` (NOT `_MISMATCH`). The second's worker then polls `getInclusionProof(requestId)` and compares the returned proof's `transactionHash` to its local one — they differ, identifying the race-loser. The loser's outbox entry transitions to `failed-permanent` with error code `OUTBOX_RACE_LOST` (reason=`'race-lost'`). The cascade rule (§6.1.1) does NOT fire for `race-lost` — the source token is genuinely valid (the race-winner's tx is on-chain); the loser's `send()` simply lost the race and the recipient never got a bundle. + +### 7.2 Migration from legacy outbox + +Source schema (`types/txf.ts:150` — `OutboxEntry`): per-token records with fields `id, status, sourceTokenId, salt, commitmentJson, recipientPubkey, recipientNametag?, amount, createdAt, updatedAt, error?, retryCount?`. + +Migration on first read: +1. Group by `(recipientPubkey, createdAt-window)` — entries created within 60s for the same recipient become a single bundle. +2. Construct a synthetic `UxfTransferOutboxEntry` per group: + - `mode: 'txf'` — legacy was always TXF wire shape with conservative-style finalization. + - `bundleCid: 'txf-' + tokenId` for single-token entries; `'legacy-' + recipientPubkey + '-' + createdAt` for combined ones. + - `deliveryMethod: 'txf-legacy'`. + - `recipient`: prefer `'@' + recipientNametag` if present, else `recipientPubkey` (preserves UI display continuity). + - `recipientTransportPubkey`: copied from `recipientPubkey`. +3. Mark `status: 'finalized'` if the legacy entry is `delivered` or `confirmed`; otherwise map to the closest UxfTransferOutboxEntry status (e.g., legacy `pending → 'sending'`, legacy `failed → 'failed-permanent'`). +4. The migration MUST preserve `recipientNametag` even when the new outbox entry's primary `recipient` field is the pubkey form — store it in the synthetic entry as part of the `error` field's metadata if no first-class slot exists, or extend the schema if needed. + +Migration is one-way; once migrated, the legacy collection is cleared. + +--- + +## 8. Token Statuses (Extended) + +PROFILE-ARCHITECTURE.md §10.11 defines statuses `valid | invalid | conflicting | pending`. The receive flow uses the same enum with the following per-disposition mapping: + +| Recipient disposition | manifest.status | Notes | +|---|---|---| +| VALID | `valid` | spendable | +| PENDING | `pending` | one or more txs in chain unfinalized; queued (§5.5) | +| CONFLICTING | `conflicting` | `conflictingHeads[]` populated; lex-min `bundleCid` is primary | +| PROOF_INVALID | `invalid` | reason ∈ {`auth-invalid`, `continuity-broken`, `proof-invalid`}; in `_invalid` | +| STRUCTURAL_INVALID | `invalid` | reason ∈ {`structural`, `predicate-eval`, `proof-throw`}; in `_invalid` | +| NOT_OUR_CURRENT_STATE | (audit only) | `_audit` collection (NEW — Wave T.3), reason='not-our-state' | +| UNSPENDABLE_BY_US | (audit only) | `_audit` collection, reason='off-record-spend' | + +The on-chain spent state is checked via `oracle.isSpent(stateHash)` — a single round-trip per finalized arriving token (cached per Wave L's bounded LRU at `oracle/UnicityAggregatorProvider.ts:158-172,608-634`). For chain-mode tokens, the spent check is **deferred** until all unfinalized txs are resolved (running it earlier would be meaningless — `isSpent` of an unproven destination state is undefined). When finalization completes (§5.5 step 9), the worker re-runs [E] before transitioning the token from `pending` to terminal. + +--- + +## 9. Error Handling and Edge Cases + +### 9.1 Bundle delivery fails (Nostr publish error) + +- Retry via outbox `failed-transient` state with exponential backoff up to a hard cap (default 24 hours). +- After cap: `failed-permanent`. Local bookkeeping is updated to reflect that the bundle did not reach the recipient. + +**Why double-spend is impossible at the protocol level**: the aggregator enforces single-spend at the SMT level via the `requestId` invariant. Per `RequestId.js`, the requestId is `SHA-256(publicKey ‖ sourceStateHash.imprint)` — deterministic given (sender pubkey, source state) and **excluding `transactionHash`**. Two different signed transitions from the same source state therefore produce DIFFERENT `transactionHash` values but the SAME `requestId`. The aggregator anchors at most ONE transition per requestId; subsequent submits for the same requestId return `REQUEST_ID_EXISTS` (NOT `_MISMATCH` — `_MISMATCH` is reserved for malformed-payload errors). The sender's worker resolves the double-spend at the polling step: + +- If the sender's original commitment was the one anchored, polling returns the proof with our `transactionHash`; idempotent success. +- If a competing commitment was anchored first (race-loser case OR the sender's local state diverged from canonical chain — "belief divergence"), polling returns the proof with a DIFFERENT `transactionHash`. The sender's worker compares and detects the mismatch, marking the queue entry `failed-permanent` with reason='race-lost'. +- If the original commitment was never accepted (aggregator dropped the submission), polling returns `PATH_NOT_INCLUDED` until the polling window expires; worker eventually marks the entry hard-failed with reason='oracle-rejected'. +- If the sender's retry uses the EXACT same `(salt, transactionHash)`, polling returns the proof with matching `transactionHash` — idempotent. + +In no case can the sender create two valid commitments for the same source state. Local outbox state is bookkeeping and cannot violate this invariant. The aggregator's single-spend invariant is the trust anchor. + +For **conservative mode** with delivery failure post-acceptance: the on-chain commitment exists (token is spent according to the aggregator), but the recipient never learned. Recovery options: +- Re-send the same UXF bundle (same CID — idempotent at the recipient). +- If re-send is also impossible (recipient's relays unreachable indefinitely), emit `transfer:lost` — funds are effectively burned from the recipient's perspective. Out-of-band coordination (operator support) is the recovery path. + +For **instant mode** with delivery failure: same recovery — the sender's local finalizer continues polling the aggregator; if finalization succeeds, the sender knows the on-chain transfer happened; the recipient is permanently unaware. Re-send retains idempotency (same bundleCid). + +### 9.2 Recipient gateway can't fetch CID + +- Recipient walks all configured gateways (default + user-overridden). +- All fail → emit `transfer:fetch-failed` event; do NOT acknowledge to sender. +- Sender's outbox times out at retry deadline; treats as transient and retries the SAME Nostr event. +- After cap: `failed-transient`. Sender SHOULD attempt CAR-embed re-delivery if the bundle is small enough. + +### 9.3 Recipient receives a UXF bundle from an unknown sender + +- The Nostr event is signed (pubkey verified by relay). Sender identity at the WIRE layer is trusted, but `payload.sender.nametag` is plaintext-attacker-controllable and MUST NOT be displayed in UI without re-resolving against the Nostr signing pubkey via the identity-binding event. +- The UXF bundle is content-addressed and verified independently per §5.2 + §5.3. +- If the recipient has no prior relationship with the sender pubkey: + - Optional friend-list / spam-filter consultation (out of scope here; existing transport-level mechanism). + - If accepted: process per §5. + - If rejected by spam policy: drop the bundle without further processing. + +**Threat-model note**: encrypted Nostr DMs already disclose the recipient's pubkey to anyone who wants to attempt delivery, so silent-drop is NOT motivated by hiding online presence. The reason for not surfacing rejection acknowledgments is to avoid amplifying spam — an attacker probing for live recipients via crafted bundles. Legitimate senders whose payload is rejected for content reasons (e.g., capability mismatch, force-cid bundle that fails to fetch) DO surface a typed error to the application layer; only spam-policy rejections are silent. + +### 9.4 Aggregator rejection — terminal hard-fail + +A queue entry transitions to terminal hard-fail through one of these paths (per §6.1): + +| Path | Trigger | Reason | +|---|---|---| +| Submit-side `REQUEST_ID_MISMATCH` | Client bug — sent inconsistent `(requestId, sourceState, transactionHash)` tuple | `client-error` (operator alert) | +| Submit-side `AUTHENTICATOR_VERIFICATION_FAILED` | Aggregator rejected our crypto | `belief-divergence` | +| Poll-side `OK` with mismatching transactionHash | Race-winner's transition was anchored; we are the race-loser | `race-lost` (cascade does NOT fire — source token is genuinely valid) | +| Poll-side sustained `PATH_NOT_INCLUDED` over POLLING_WINDOW | Commitment was never anchored | `oracle-rejected` | +| Poll-side `PATH_INVALID` after retries | Proof structurally malformed | `proof-invalid` | +| Poll-side `NOT_AUTHENTICATED` after retries | Stale local trustBase (per §9.4.1; active forgery out of scope) | `proof-invalid` (also: `transfer:trustbase-warning`) | + +After hard-fail: +- The specific failing transaction is marked invalid with the canonical reason. +- Per §6.1.1 cascade rule, locally-derived child tokens of this token are also marked `'invalid'` with reason=`'parent-rejected'`. +- The **source token (parent)** is untouched — the failed transition is treated as if it never happened. The aggregator's single-spend invariant means the token remains in its prior valid state in the original owner's pool. + +**No refund / reversal protocol is needed** (per §12.1). + +**Mode-specific severity**: +- **Instant mode**: a hard-fail is a routine outcome of optimistic shipping — the sender went before knowing the aggregator's verdict. No security implications unless reason ∈ {`belief-divergence`, `proof-invalid`}. +- **Conservative mode**: the sender retrieved a proof BEFORE shipping the bundle. The recipient may observe either (a) `NOT_AUTHENTICATED` — most likely a stale local trustBase per §9.4.1 (active forgery is out of scope) → `transfer:trustbase-warning`; OR (b) `PATH_INVALID` — proof structurally malformed → `proof-invalid` hard-fail with retry. In conservative mode specifically, a sustained NOT_AUTHENTICATED after trustBase refresh is operationally suspicious because the sender claimed the proof was already verified; the SDK MAY emit `transfer:security-alert` after the trustBase-refresh path is exhausted, signaling that the trust boundary may have been violated. + +#### 9.4.1 Threat boundary (faulty vs hostile) + +The protocol assumes the aggregator is **faulty, never hostile**. Faulty means: +- May drop submissions (transient → retry). +- May return transient errors (5xx, network hiccups → retry). +- May briefly return inconsistent state (e.g., `PATH_NOT_INCLUDED` on a poll for a commitment another peer just got `OK` for, due to not-yet-replicated state across aggregator nodes → keep polling within the window). + +In-scope failure modes the protocol defends against: +- Aggregator drops or delays a submission. Worker retries; eventually anchored or POLLING_WINDOW expires. +- Aggregator briefly returns wrong errors (one node out of date). Worker retries; consistent answer eventually. +- Aggregator is unavailable. Worker keeps retrying within transient budget; UI surfaces stuck-PENDING after 7 days; operator can paste in a proof out-of-band via `payments.importInclusionProof`. + +Out-of-scope failure modes (the protocol does NOT defend against; if these occur, the trust assumption is violated): +- Aggregator signs valid proofs for transitions not in its SMT (active forgery). Detected by recipient's local trustBase verify, but only if the trustBase is up-to-date. +- Aggregator collusion across BFT validators to rewrite history. Detection at the BFT layer is out-of-scope here; if it happens, the recipient may store a `valid` token whose chain is later contradicted by a corrected aggregator — manual operator escalation required. +- Aggregator deliberately returns inconsistent answers to different callers (split-brain). The most-recent-proof canonicalization in §6.3 handles benign multi-round divergence (proofs at different snapshots for the same value); deliberate split-brain on different SMT roots OR different values for the same requestId is a hostile-aggregator scenario and out of scope (the latter triggers `transfer:security-alert` per §6.3). + +**Event taxonomy**: +- `transfer:trustbase-warning` — `NOT_AUTHENTICATED` on a proof. Most likely cause: stale local trustBase. The SDK SHOULD attempt a trustBase refresh before retrying. The protocol does NOT defend against active forgery (out of scope), so this event is treated as an operational issue rather than a security incident. +- `transfer:security-alert` — reserved for the explicit out-of-scope cases that the protocol detects but cannot defend against (e.g., two structurally-different valid proofs for the same requestId, retrieved by separate workers and observed via `pkg.merge`). This event is informational and signals "the trust boundary may have been violated" — operator investigation required. + +For the chain-mode case, only the specific failing tx is the trigger, but the cascade rule (§6.1.1) and the §5.5 step 7 short-circuit ensure the WHOLE token is invalidated immediately upon any chain link's hard-fail. + +### 9.5 Sender restarts mid-finalization + +Outbox is persisted in OrbitDB. On restart, `FinalizationWorker` resumes from where it left off. No data loss because: +- The commitment requestIds are recorded in the outbox before send. +- The aggregator's `getInclusionProof(requestId)` is idempotent. +- The local pool's pending transaction can be patched in-place once the proof is fetched. + +### 9.6 Recipient restarts mid-finalization + +Per-address finalization queue is persisted in OrbitDB (per-entry-key per Wave G.7). On restart, the queue is rehydrated and the worker resumes. Same idempotency as 9.5. + +### 9.7 Bundle contains a token whose chain has a Rule-4-eligible alternative in our pool + +Per Wave G.3, this triggers `resolveTokenRoot` with the bundle's verified proofs. The synthetic enriched root is computed and stored; manifest's primary root is the JOIN winner; both originals become losers. Status: `valid` if the JOIN converges; `conflicting` if divergent. + +### 9.8 Two bundles arrive in close succession with overlapping tokens + +Each is processed in arrival order. The second's tokens go through the per-token decision matrix. Conflict-check `[F]` (§5.3) may return `CONFLICTING` for any tokenId now present in two distinct chains, OR may return `VALID/PENDING` after a monotonic merge if one chain is a strict prefix/extension of the other. The chain-mode merge path (§5.6) is the mainline case for partially-overlapping arrivals. + +--- + +## 10. Backward Compatibility + +The TXF wire shapes are **permanent**, not deprecated. There is no migration window and no `WIRE_FORMAT_DEPRECATED` error path. UXF is the default; TXF is the explicit opt-in alternative for cases that require it. + +### 10.1 Sender side + +`PaymentsModule.send(...)` accepts: +- `coinId: string`, `amount: string` — primary coin slot. Required by the type for v1.0 backward compatibility; the implementation wave widens the type to `coinId?: string; amount?: string;`. Post-widening, NFT-only sends omit both fields. Until the widening releases, NFT-only sends are not expressible against the v1.0 type signature (per §4.1 — there is no valid placeholder). +- `additionalAssets?: ReadonlyArray` — multi-asset extension where `AdditionalAsset = {kind:'coin', coinId, amount} | {kind:'nft', tokenId}`. When present, target list construction follows §4.1 step 1 (primary coin slot prepended if both `coinId` and `amount` are present; additionalAssets appended verbatim). Distinct-coin and distinct-NFT-tokenId rules apply. Receivers reject unrecognized `kind` values with `UNKNOWN_ASSET_KIND` (forward-compat). Omitting this field preserves single-coin behavior identically to prior SDK versions. +- `confirmNftPending?: boolean` — default `false`. Required = `true` to send NFT-class targets backed by pending source tokens (per §4.1 step 2 cascade asymmetry warning). The flag exists to ensure callers explicitly acknowledge that a cascaded NFT is irrecoverable — there is no fungible replacement for an NFT identity. +- `transferMode: 'instant' | 'conservative' | 'txf'` — default `'instant'`. +- `txfFinalization: 'instant' | 'conservative'` — only applies when `transferMode === 'txf'`; default `'conservative'`. +- `delivery: DeliveryStrategy` (UXF modes only; see §3.3.1) — default `{ kind: 'auto', inlineCapBytes: 16384 }`. +- `allowPendingTokens?: boolean` — default `false`. Per §2.5 chain-mode opt-in. + +Callers that don't specify any of these get the UXF bundle behavior in instant mode with the 16 KiB auto cutoff and finalized-tokens-only selection. + +> **Breaking-widening note**: extending `TransferMode` from `'instant' | 'conservative'` (existing) to `'instant' | 'conservative' | 'txf'` is non-breaking for runtime code paths, but breaking for any TypeScript exhaustiveness check (`switch(mode) { case 'instant': … case 'conservative': … }` without a default arm). Affected call sites must add the `'txf'` arm explicitly. Audit will be performed in Wave T.7. + +There is **no automatic capability-based fallback** from UXF to TXF. The capability hint in the recipient's identity binding (informational) MAY surface a UI warning, but the SDK never silently switches modes.

D receives a token with 3 unfinalized txs. D's worker resolves all 3; status transitions `pending → valid` only after the third proof attaches. + - Same chain, but D imports a more-finalized backup of the same `tokenId` mid-resolution. The backup's proofs short-circuit the queue. + - Multi-coin token transferred mid-chain — verify the recipient correctly re-derives the requestId for the multi-coin parent's pending split tx. +- **Multi-coin tokens (single-coin send from multi-coin source)**: + - A token containing `{UCT: 100, USDU: 50}` is sent for `(UCT, 30)` only. Verify change stays at sender with `{UCT: 70, USDU: 50}`; recipient receives a child token with `(UCT, 30)`. + - Same, but change is sent in a follow-up transfer to a third party. +- **Multi-coin send (additionalAssets, all coin entries)**: + - Single multi-coin source `{UCT: 100, USDU: 50, ALPHA: 1000}` sent with `coinId='UCT', amount='30', additionalAssets=[{kind:'coin', coinId:'USDU', amount:'20'}]`. Recipient receives one child token with `{UCT: 30, USDU: 20}`; change has `{UCT: 70, USDU: 30, ALPHA: 1000}`. + - Multiple sources (A `{UCT: 100}`, B `{USDU: 50}`) covering `coinId='UCT', amount='30', additionalAssets=[{kind:'coin', coinId:'USDU', amount:'20'}]`. Recipient receives TWO child tokens (one per source); change has two tokens (`{UCT: 70}` from A, `{USDU: 30}` from B). +- **NFT-only send** (NFT = token with empty/null coinData): + - Source: NFT-token `T` (tokenId=`0xabc`, empty coinData), owned by sender. Request omits primary `coinId`/`amount`; `additionalAssets: [{kind: 'nft', tokenId: '0xabc'}]`. Recipient receives `T'` with the SAME tokenId; coinData still empty; current state binds to recipient. No split, no change token (whole-token state-transition). + - Multiple NFTs: request omits primary; `additionalAssets: [{kind:'nft', tokenId:T1}, {kind:'nft', tokenId:T2}]`. Bundle carries two whole-token transfer transactions; recipient gets both NFTs with original tokenIds preserved. +- **Mixed coin + NFT send** (separate sources only): + - Source A `{UCT:100}` (coin token) + source B (NFT-token, empty coinData). Request: `coinId:'UCT', amount:'30', additionalAssets:[{kind:'nft', tokenId:B.id}]`. Split A: recipient-A `{UCT:30}` (fresh tokenId) + change-A `{UCT:70}` (fresh tokenId). Whole-transfer B: recipient-B `B'` with preserved tokenId. Bundle carries both; recipient receives two child tokens. +- **Validation rejections**: + - `additionalAssets` containing duplicate `coinId` (e.g., `{kind:'coin', coinId:'UCT', amount:'10'}` when primary is also UCT) → `INVALID_REQUEST`. + - `additionalAssets` containing duplicate NFT `tokenId` → `INVALID_REQUEST` (cannot transfer same NFT twice). + - `additionalAssets` coin entry with `amount: '0'` → `INVALID_AMOUNT`. + - `additionalAssets` entry with unrecognized `kind` (e.g., a future `'voucher'` shipped to a v1 receiver) → `UNKNOWN_ASSET_KIND` (forward-compat reject rule). + - Insufficient coin balance for any coin target → `INSUFFICIENT_BALANCE`; no partial shipment. + - NFT not in sender's pool → `INSUFFICIENT_BALANCE` reason='nft-not-owned'. + - NFT in pool but current-state predicate doesn't bind to sender → `INSUFFICIENT_BALANCE` reason='nft-not-owned'. + - **NFT target's source is a coin token (non-empty coinData)** rather than an NFT token → `INSUFFICIENT_BALANCE` reason='nft-not-owned'. Coin tokens cannot satisfy NFT targets even if `tokenId` matches; the protocol enforces class disjointness (per §4.1 canonical asset model). + - Empty transfer (no primary AND empty/missing additionalAssets) → `EMPTY_TRANSFER`. + - **Pending NFT without confirmation**: `allowPendingTokens: true` + NFT target whose source has unfinalized predecessor txs + `confirmNftPending: false` (default) → `NFT_PENDING_REQUIRES_CONFIRMATION`. With `confirmNftPending: true`, the send proceeds; cascade asymmetry warning applies. +- **Backward compat**: single-coin call `{coinId: 'UCT', amount: '30'}` (no `additionalAssets`) produces byte-identical bundle to a v1.0-spec call → regression test against a captured fixture. **Implementation note**: the fixture MUST be generated from a tagged commit (specify the tag in the test) with deterministic salt, deterministic timestamp, and a recorded mnemonic; committed under `tests/fixtures/uxf-v1-single-coin/`. The byte-identical assertion is gated on the fixture's existence. +- Token-hash invariance: take the same token in two states (proof attached vs. proof null), verify `token.id` is identical, verify CIDs differ. +- CAR-embed delivery for small bundles (< 16 KiB); CID delivery for large bundles (> 16 KiB). +- **Inline delivery completion semantics (§3.3.2)**: + - Sender ships an inline bundle, Nostr relay acks → outbox transitions to `delivered` (or `delivered-instant`). + - Sender ships an inline bundle, all configured relays reject → outbox stays at `sending`, retries; eventually `failed-transient`. + - Recipient receives Nostr event, decrypts, parses CAR successfully → bundle delivered, §5.3 disposition pass runs. + - Recipient receives Nostr event, CAR fails to parse (corrupted base64 or root-CID mismatch) → bundle rejected, no delivery acknowledgment. +- **CID delivery completion semantics (§3.3.2)**: + - Sender pins CAR to IPFS successfully + Nostr relay acks → outbox transitions to `delivered`. + - Sender's IPFS pin succeeds but Nostr publish fails → outbox stays at `pinned`; on retry, only the Nostr publish is re-attempted (CID is already pinned). + - Sender's Nostr publish succeeds but IPFS pin fails (out of disk, gateway timeout) → outbox stays at `pinned`; pin is retried; on permanent pin failure, outbox transitions to `failed-permanent` even though the Nostr event was published (the CID won't resolve for the recipient). + - Recipient receives Nostr event with CID, all gateways fail to fetch within retry budget → `transfer:fetch-failed` emitted; bundle is NOT delivered; sender's outbox times out. + - Recipient receives Nostr event with CID, one gateway succeeds → CAR verified against bundleCid, bundle delivered, §5.3 runs. + - **Cross-mode test**: sender ships in instant mode via CID; recipient's IPFS fetch succeeds 5 minutes after Nostr event arrival → recipient's instant-mode finalization queue starts at the IPFS-fetch time, not at the Nostr-event time (per §3.3.2 "physically syncing" rule). +- `delivery: { kind: 'force-inline' }` with an oversized bundle → expect `INLINE_CAR_TOO_LARGE` error. +- `delivery: { kind: 'force-cid' }` with a 1-token tiny bundle → IPFS pin happens (or no-op since the outbox already pinned), recipient fetches via gateway. +- `delivery: { kind: 'auto', inlineCapBytes: 32768 }` — 24 KiB bundle goes inline despite default cap being 16 KiB. +- Instant-mode sender restarts before finalization; resumes from outbox. Outbox carries entries for all unfinalized txs. +- Recipient restarts with chain-mode tokens (multiple txs pending) in queue; resumes and resolves all. +- Conflict scenario: same tokenId arrives in two different bundles; JOIN converges. Same tokenId arrives in two bundles with overlapping-but-not-identical proof sets; merge accumulates monotonically. +- Hostile-bundle scenarios: STRUCTURAL_INVALID, PROOF_INVALID, NOT_OUR_CURRENT_STATE, UNSPENDABLE_BY_US, CONFLICTING. Each surfaces correctly. + +### 11.3 Compatibility tests + +- TXF-mode sender → UXF-aware recipient: legacy adapter produces correct dispositions for all 4 legacy shapes; tokens land in the OrbitDB profile. +- UXF-mode sender → TXF-only recipient (simulated): send fails with typed error; caller's explicit retry with `transferMode: 'txf'` succeeds. +- Outbox migration: legacy per-token entries become bundle-grained correctly; TXF entries stay per-token with `deliveryMethod: 'txf-legacy'`. +- Capability hint: identity binding declares `wireProtocols: ['txf']` only — sender UI warns; SDK does NOT auto-switch. + +### 11.4 Adversarial tests (steelman seeds) + +- Sender claims `mode: 'conservative'` but bundle has unfinalized transactions → recipient processes per bundle contents (mode field is advisory); token enters `pending`. +- Sender claims `mode: 'instant'` but bundle has all proofs → recipient processes per §5.3; token enters `valid` after oracle isSpent check. +- Bundle CID hash collision (sender forges a DIFFERENT CAR with the same root CID — only possible via SHA-256 collision, theoretical) → defended at the per-block hash-verify stage of `UxfPackage.fromCar`. +- CAR with multiple roots (smuggling attempt) → rejected at `pkg.verify()` step (§5.2 #1 — multi-root MUST fail, normative). +- Bundle DAG contains token-roots NOT in `payload.tokenIds` (smuggling attempt) → recipient processes them anyway, [B] ownership filter rejects ones that don't bind to us → `NOT_OUR_CURRENT_STATE` in `_audit`. +- Forged `payload.sender.nametag` (attacker claims `@victim`) → recipient discards plaintext nametag, re-resolves against Nostr signing pubkey via identity binding → mismatch surfaced. +- Replay: identical bundleCid sent 100 times → 1 processed, 99 short-circuited via LRU; if LRU evicts, re-processing is benign (idempotent per §5.6 invariant). +- Instant-mode + concurrent split: 5 split outputs all unfinalized → 5 separate finalizations → all converge. Parent's still-pending tx is also finalized in parallel. +- Recipient's local clock skewed by 30 days → finalization worker still runs (no clock-dependent guards). +- Chain-mode forwarder dies mid-chain: the token's queue carries entries for the predecessor's pending tx; finalization still completes via the local worker (predecessor's signedTx is in the bundle the forwarder received). +- Forged authenticator on an unfinalized tx (tx claims to be signed by previous owner but isn't) → §5.3 [C](1) ECDSA verify fails → `PROOF_INVALID`. **Critical**: this MUST be detected at receive, not deferred to aggregator-poll time. +- **Bandwidth-burning peer**: malicious sender forwards a 10-deep chain where tx #3's commitment never anchored (sustained PATH_NOT_INCLUDED at recipient's worker). Recipient's worker hits the hard-fail at tx #3 after the polling window; per §6.1 short-circuit, the WHOLE token is marked invalid immediately and other queue entries are cancelled. Test verifies (a) the bundle is processed correctly, (b) the chain-depth cap fires for bundles with >64 unfinalized txs in the *claimed* tokenIds (smuggled deep roots are silently dropped per §5.2 #3 — separately tested). +- **Peer-reputation cooldown (deferred)**: assertion that the recipient applies a 1-hour silent-drop window for further bundles from a peer that recently shipped a hard-failing chain — DEFERRED per §12.2 (peer-reputation framework not in T.1-T.8). Add this test only when the framework lands. +- **Faulty-aggregator path (intermittent PATH_NOT_INCLUDED)**: aggregator returns PATH_NOT_INCLUDED transiently (e.g., across an aggregator-node-restart). Worker keeps polling; eventually one poll returns OK and the token finalizes correctly. Verify that the worker DOES NOT terminate on first PATH_NOT_INCLUDED (it's the not-yet status, not a hard-fail). +- **Race-lost detection (poll-side)**: two replicas submit different transitions over the same source state. Both get `SUCCESS` or `REQUEST_ID_EXISTS` at submit. The race-loser's poll returns `OK` with a `transactionHash` that doesn't match its local one. Worker hard-fails with reason='race-lost'; cascade does NOT fire (the source token is genuinely valid). +- **Client-error at submit (REQUEST_ID_MISMATCH)**: simulate a buggy client that computes requestId incorrectly. Aggregator returns REQUEST_ID_MISMATCH. Worker hard-fails with reason='client-error'; emits operator alert; cascade does NOT fire (the source token is unaffected — no transition was registered). +- **Sustained PATH_NOT_INCLUDED past polling window**: simulate aggregator that persistently returns PATH_NOT_INCLUDED for the entire 30-min window. Worker hard-fails with reason='oracle-rejected' after the deadline. +- **Conservative-mode post-send PATH_INVALID**: hard-fail with reason='proof-invalid' after retries. +- **Conservative-mode post-send NOT_AUTHENTICATED**: emit `transfer:trustbase-warning`; attempt trustBase refresh; if still failing, hard-fail and emit `transfer:security-alert` (sustained-after-refresh case only). +- **OrbitDB CRDT replica merge**: simulate two replicas writing different `status` updates for the same outbox entry concurrently — verify monotonic-state-machine LWW resolution (more-advanced state wins), no `finalized → sending` regressions. +- **Stuck-PENDING escape**: token is `pending` for >7 days; operator pastes in a proof via `payments.importInclusionProof()` → proof grafts in, token transitions to `valid`. + +--- + +## 12. Resolved and Deferred Questions + +### 12.1 Resolved + +- **Refund / reversal protocol on aggregator rejection**: NOT needed. The hard-rejection signals are sustained `PATH_NOT_INCLUDED` over the polling window (oracle-rejected — commitment never anchored) or poll-side `OK` with mismatching transactionHash (race-lost — a different transition won the submit-race). See §6.1 error model. In both cases, the transaction OUR worker tried to anchor never made it on-chain — the source token's actual state is whatever the canonical aggregator chain shows (either unchanged for oracle-rejected, or transitioned by the race-winner for race-lost). Both sender and recipient mark the *attempted* transition as invalid; the underlying token's true on-chain state is unchanged from the wallet's perspective. No reversal flow required. (Per-history-tx invalidations propagate up to the whole-token level; see §6.1.1 cascade rule + §6.3 failure mode.) +- **Aggregator-driven inbound discovery**: NOT possible. The aggregator never holds the full transaction — only its commitment. A recipient who never received the Nostr/UXF delivery cannot reconstruct the token from the aggregator alone. Existing payment-request + reconciliation flows are the recovery path. + +### 12.2 Deferred + +- **Bundle compression**: CARs can be sizeable for many-token bundles (especially chain-mode tokens with deep history). zstd / brotli on the inline-CAR path? Out of scope for v1.0. +- **Multi-recipient bundles**: a single UXF bundle delivered to a Nostr group / multicast — nice to have, deferred. Would amortize CID-pin cost across N recipients and allow group-level atomic broadcasts. Open design points: per-recipient encryption envelope vs. shared symmetric key, group-membership consent. +- ~~**Multi-coin / multi-asset send in a single call**~~ — implemented (in spec). `PaymentsModule.send()` accepts the optional `additionalAssets: AdditionalAsset[]` field on `TransferRequest` where `AdditionalAsset = {kind:'coin', coinId, amount} | {kind:'nft', tokenId}`. The primary `coinId`/`amount` slot is OPTIONAL (semantically; the type retains them for backward compatibility, with the implementation wave widening them to optional fields). NFT and coin source tokens are class-disjoint per §4.1 canonical asset model — no mixed-asset tokens. NFT transfers are whole-token; coin transfers may split. See `docs/API.md` and `docs/INTEGRATION.md`. +- **Mixed-asset tokens (single token carrying coins + NFT identity simultaneously)**: NOT supported in v1. Would require a new SDK primitive (e.g., a "split-with-id-carry" operation that preserves `tokenId` while modifying `coinData`). Reserve for a future protocol revision if a real use case emerges. +- **Conflict-resolution UI/API**: `CONFLICTING` tokens (genuinely-divergent chains) need an explicit `resolveConflict(tokenId, chosenHead)` API and UI surface. Lex-min `bundleCid` provides an automatic primary, but operator override is a planned future addition. +- **Peer-reputation framework**: §11.4 mentions a 1-hour cooldown on bandwidth-burning peers. The reputation interface itself is out of scope here. Note: peer-reputation rises in operational importance once NFTs are in scope — a peer who delivers a forged or cascade-prone NFT chain can corrupt the recipient's collection in a way coin damage cannot (NFTs are non-fungible / non-replaceable). Reserve a future protocol revision for per-peer trust scores or signed NFT-receipt acknowledgements. + +### 12.3 Periodic rescans (two orthogonal scanner types — split status) + +> **Status update (2026-05-19)**: the original §12.3 framed BOTH rescans as deferred at the time T.1–T.8 were planned. Both have since landed: +> +> - **§12.3.1 (profile-pointer rescan) is SHIPPED** — landed as the core of the **aggregator-pointer wave** (`PROFILE-AGGREGATOR-POINTER-IMPL-PLAN.md` Phases A–E, 75 tasks) and consolidated by **Item #15** (Full Profile State Snapshot Sync; merged via PR #173). Implementation in `profile/profile-token-storage/lifecycle-manager.ts` (`schedulePointerPoll` / `runPointerPollOnce`). +> - **§12.3.2 (per-token spent-state rescan) is SHIPPED** — landed via **Issue #174** / PR #176 (`feat/spent-state-rescan-worker`), with the default closure in PR #177 and the soak-gate flip in PR #178. Implementation in `modules/payments/transfer/spent-state-rescan-worker.ts`; wired into `PaymentsModule` behind the `features.spentStateRescan` flag (default-ON; explicit `false` opt-out preserves the reactive-only surface). +> +> The "two rescans deferred as a unit" language in `UXF-TRANSFER-IMPL-PLAN.md`'s "Out-of-scope for T.1–T.8 (deferred)" section is similarly stale (kept for historical accuracy of what shipped in T.1–T.8 specifically; both rescans landed outside the T.1–T.8 wave bucket). + +The protocol relies on two periodic rescan loops to maintain consistency between local state and the canonical aggregator/profile views. Both are operator-configurable and run independently: + +#### 12.3.1 Profile-pointer rescan — **SHIPPED** + +**Purpose**: detect updates to the wallet's UXF profile that landed via another instance of the same wallet (different device, recovered backup, etc.). The profile pointer is registered with the aggregator; periodically, the local instance queries the latest pointer position to discover whether a remote update has bumped it. + +**Mechanism**: +- Schedule: every `PROFILE_POINTER_RESCAN_INTERVAL` (default 30s, randomized in `[30s, 90s)` in the as-implemented version to avoid synchronized polling herds across devices booting simultaneously). +- Query: `pointer.recoverLatest()` — returns the latest pointer version anchored to the wallet's chain pubkey, content-verified end-to-end (inclusion proof + trust base + CAR content-address verify). +- On bump: fetch the new profile CID locally, parse as a `LeanProfileSnapshot` per Item #15, dispatch per-writer JOIN via `applySnapshotIfWired(cid)` (OUTBOX / SENT / disposition / finalization-queue / recipient-context / bundle-refs). Run §5.3 disposition matrix on any new tokens via the existing disposition writer path. +- Hint channel: `OrbitDbAdapter.onReplication` calls `triggerPointerPollNow()` so a pubsub event collapses worst-case cross-device sync latency from ~90s to ~1-2s on healthy infra. Pubsub is explicitly DEMOTED to a hint channel per Item #15; the aggregator pointer is the authoritative source. +- Backoff on transient errors: standard interval continues. Permanent classifier (e.g. `AGGREGATOR_POINTER_TRUST_BASE_STALE`) triggers a 5× back-off ([150s, 450s)) AND emits `storage:error` for operator visibility. + +This rescan is the primary mechanism by which the audit-collection promotion scanner (formerly listed in §12.2 as deferred) actually fires — when a remote update brings in a new transfer that makes a previously `audit-not-our-state` token ours, the rescan-driven §5.3 pass detects the new ownership and promotes per §5.4. + +**Operator override**: omitting the `getPointerLayer` accessor / not wiring an oracle disables the polling entirely (the lifecycle manager silently skips when no pointer closure is wired). There is no `{ disableProfilePointerRescan: true }` SDK init flag — the wiring presence IS the on-switch. + +#### 12.3.2 Per-token spent-state rescan — **SHIPPED** (Issue #174) + +**Purpose**: detect off-record spends. If another instance of the same wallet (sharing the private keys but not yet synced to us) has spent one of our tokens, the aggregator's SMT will show that token's current state as having a committed transition — but our local manifest still believes the token is `valid`. **Without rescan, we'd attempt to spend an already-spent token and learn the truth only at next `send()`** (which surfaces as the typed `STATE_ALREADY_SPENT_BY_OTHER` throw + `transfer:double-spend-detected` event — the REACTIVE surface, Item #14 Phase 1 / commit `9b4fae7`). The PROACTIVE surface catches it earlier so the local UI doesn't continue showing the token as spendable until the user tries to spend it. + +**Mechanism**: +- Schedule: for each token in the active pool with `manifest.status === 'valid'` (= local `Token.status === 'confirmed'`), query `oracle.isSpent(currentDestinationStateHash)` periodically. Default interval `TOKEN_SPENT_RESCAN_INTERVAL = 5 min` per token; cap concurrent in-flight queries at `MAX_CONCURRENT_SPENT_RESCANS` (default 4). +- On `isSpent === true`: transition the token from active pool to `_audit` with `reason='off-record-spend'` (UNSPENDABLE_BY_US disposition per §5.3 [E]). Emit `transfer:off-record-spent` event with `{ tokenId, detectedAt, suspectedSiblingInstance, coinId, amount }` — `suspectedSiblingInstance` is `true` when neither the local OUTBOX nor the local SENT ledger holds any record referencing this `tokenId`, indicating the spender is most likely another instance with the same keys. +- On transient errors (aggregator unavailable / `oracle.isSpent` throw): bump a per-token throw counter. After `consecutiveThrowBackoffThreshold` (default 3) consecutive throws on the SAME token, apply a per-token back-off (`throwBackoffMs`, default 30 min) so a stuck token cannot hammer the aggregator. A successful probe (true OR false) clears the counter. +- Cache: §8 already references the Wave L LRU cache for `isSpent`. The rescan respects the cache TTL — the per-token interval (5 min) is intentionally aligned with the LRU TTL so the worker piggybacks on the cache instead of bypassing it. +- Feature flag: `features.spentStateRescan` (default-ON after soak; explicit `false` opt-out for cost-sensitive deployments that accept the reactive `transfer:double-spend-detected` surface alone). + +**Relationship to other surfaces**: +- **Complementary to §12.3.1**: the profile-pointer rescan catches the spend IF the spending device publishes a snapshot to the aggregator before our local poll fires. §12.3.2 catches it independently of whether the spender device's snapshot has propagated. +- **Complementary to Item #14 Phase 1 (REACTIVE)**: Phase 1's `transfer:double-spend-detected` fires at our next `send()` attempt. §12.3.2 is the PROACTIVE surface — fires from the background sweep before any send attempt. +- **Distinct from orphan-spending sweeper** (Item #166 P2 #1): that sweeper looks at tokens stuck `'transferring'` with no matching OUTBOX/SENT entry. §12.3.2 looks at tokens at `'confirmed'` AND in the active manifest — disjoint sets by the eligibility filter. + +**Operator override**: `{ features: { spentStateRescan: false } }` disables the worker. Disabling leaves the wallet dependent on the reactive surface (Item #14 Phase 1) for off-record-spend detection. + +--- + +## 13. Implementation Plan (deferred to UXF-TRANSFER-IMPL-PLAN.md) + +The implementation will land in waves: + +- **Wave T.1** — Wire-format types. `UxfTransferPayload` discriminated union, `DeliveryStrategy`, `transferMode: 'instant' | 'conservative' | 'txf'`, `txfFinalization: 'instant' | 'conservative'`, payload encode/decode helpers, unit tests. Audit and update existing `TransferMode` exhaustiveness checks (breaking-widening per §10.1). Add `_audit` collection key to `PROFILE_KEY_MAPPING`. Define `DispositionReason` and `AuditStatus` enums. +- **Wave T.2** — Sender bundle construction for **conservative mode** (UXF wire) + CAR-embed delivery with the 16 KiB default cap + `force-inline` / `force-cid` / custom `inlineCapBytes` per-call overrides. Fixed conservative 96 KiB hard ceiling; NIP-11 relay-discovery is deferred per §12.2. Publish-time relay-rejection auto-falls-back to CID for `delivery: 'auto'`. Conservative ships first because the chain has no unfinalized tail when it goes out. Sender also walks the source token's history and finalizes any inherited pending txs before bundle build. +- **Wave T.3** — Recipient bundle ingest + decision matrix + storage outcomes. Implements §5.3 [A]–[F] including: + - Throw-path → STRUCTURAL_INVALID escapes at every branch. + - Mandatory ECDSA authenticator verification at [C](1) — full crypto, not deferred. + - Single-root + multi-root rejection as a normative MUST. + - Chain-depth cap (default 64) as a hard reject at §5.2. + - Fetched-CAR size cap (default 32 MiB) as a hard reject during gateway pull. + - `_audit` collection (NEW) at `${addr}.audit.${tokenId}` with promotion semantics. + - `tokenIds` is advisory; recipient processes every token-root in the pool and filters at [B]. + - No instant-mode handling yet (recipient rejects bundles whose `mode === 'instant'` with a typed soft-error so T.2-only deployments don't drop tokens silently). +- **Wave T.4** — CID-pin delivery for large bundles (sender uses the already-pinned outbox CID; recipient fetches via verified-CAR pipeline with the 32 MiB cap).

The 2s burn-proof wait that V5 sustains is fundamental to the protocol-level `SplitMintReason` validation; V4's "skip burn proof, ship mint commitments immediately" model is incompatible with the SDK's split semantics. Recommended action: keep V4 dev-mode only, document the constraint, and revisit only if the SDK adopts a redesigned split-proof model. + +## Background + +PR #207 raised the question of whether V4 could be flipped from dev-mode to production. The hope: ~0.3s sender critical path (vs. ~2.3s in V5) by deferring the burn-proof wait to the receiver's chain-walker. + +Prerequisite asserted by the user: the SDK's token-digest computation must be **proof-independent**. We verified this — `Token.toJSON()` (`@unicitylabs/state-transition-sdk/lib/token/Token.d.ts`) and the underlying `MintTransaction` / `TransferTransaction` shapes nest `inclusionProof` as a separate sibling of `data`, and the deterministic identity of a transition is `RequestId.create(publicKey, sourceStateHash)` — neither depends on a proof being present. ✓ + +But the second constraint, which makes V4 fail in production: **`SplitMintReason` requires a proven burn**. + +## SDK constraint — `SplitMintReason` requires a `burnedToken` + +`TokenSplitBuilder.createSplitMintCommitments(trustBase, burnTransaction)` +(`node_modules/@unicitylabs/state-transition-sdk/lib/transaction/split/TokenSplitBuilder.js:71-74`): + +```js +async createSplitMintCommitments(trustBase, burnTransaction) { + const burnedToken = await this.token.update(trustBase, + new TokenState(new BurnPredicate(...), null), + burnTransaction); + return Promise.all(this.tokens.map((request) => + MintTransactionData.create(..., new SplitMintReason(burnedToken, ...)) + .then((data) => MintCommitment.create(data)))); +} +``` + +Two things make V4 incompatible: + +1. **`token.update(trustBase, ..., burnTransaction)`** — verifies the burn transaction's inclusion proof. With only a burn *commitment* (V4's shape), this verification fails. The SDK is the gate; the aggregator is downstream. + +2. **`SplitMintReason` carries the burned token state** — a `Token` instance reflecting the post-burn state. That instance cannot be constructed without a proven burn (`token.update()` returns the new `Token`). + +Even if we could route around (1) by injecting a synthetic "unverified burned token", the aggregator's mint-commitment validation re-derives the `SplitMintReason` proof chain and would reject mints whose burn isn't anchored. V4's only way around this is "dev mode" — which is exactly the regime where this validation is skipped. + +## Failure model if V4 ships in production + +Hypothetical V4-production sender flow: +1. Create burn commitment (no proof). +2. Construct mint commitments referencing the unproven burn. +3. Submit mint commitments first → **aggregator rejects** because `SplitMintReason` doesn't validate. + +If the aggregator's rejection were silent or asynchronous, the failure model gets worse: +- Sender's UI marks the transfer as "succeeded" after Nostr delivery. +- Receiver runs the chain-walker, sees burn → unprovable, mint → rejected, and has a permanently un-finalizable mint commitment. +- No mechanism on the receiver to undo or detect — the source token state, meanwhile, is in `committedOnChainTokenIds`. + +This is the same "stranded receive" pathology #144 / #199 fought to eliminate. V5's 2s burn-proof wait is what prevents the sender from advertising a transfer that can't complete. + +## What would V4-production actually require? + +Hypothetical redesign that would let V4 work: +- A new aggregator commitment shape that accepts a mint without `SplitMintReason`, then anchors the mint to the eventual burn proof in a later validation round. +- Equivalent SDK support (a `MintTransactionData` variant without `SplitMintReason`, plus a "post-anchor" step that links mint → burn after the burn proves). +- Receiver-side detection + cleanup for the "burn never proved" failure mode (e.g., the sender's burn request collided with another spend of the same source token). + +This is a substantial protocol change spanning aggregator, state-transition SDK, and wallet.

Responsibilities, in order: + * + * 1. **CID-mode branch (T.4.B)** — if `payload.kind === 'uxf-cid'`, + * delegate to {@link fetchCarByCid} (cid-fetcher.ts). The fetcher + * walks the configured gateway list, stream-fetches under the + * 32 MiB cap, and verifies the CAR root CID matches `bundleCid`. + * On success we re-enter the CAR-validation path with the fetched + * bytes. On all-gateways-failure, the fetcher emits + * `transfer:fetch-failed` and throws + * `BUNDLE_REJECTED_FETCH_FAILED_TRANSIENT` — the worker pool + * treats this as TRANSIENT (W13: NO disposition record). + * + * **Gateway list resolution** (§3.3): we use the wallet's own + * configured gateway list, NOT `payload.senderGateways` (the + * latter is informational only — a hostile sender could lie). The + * caller passes the resolved gateway list via `options.gateways`. + * + * 2. **CAR root-CID extraction** — decode `payload.carBase64` to bytes + * and run `extractCarRootCid` (T.1.D). This catches: + * - `BUNDLE_REJECTED_INVALID_CAR` — bytes don't parse as CARv1. + * - `BUNDLE_REJECTED_MULTI_ROOT` — CAR has ≠ 1 root (§5.2 #1). + * Both are forwarded as-is from T.1.D's helper. + * + * 3. **Root-CID consistency** — confirm the extracted root CID matches + * `payload.bundleCid`. The sender authenticates the bundle by + * committing to its CID in the outer envelope; a mismatch means + * the sender lied about which CAR they're shipping (or the CAR + * was swapped in transit). Reject with + * `BUNDLE_REJECTED_ROOT_CID_MISMATCH`. + * + * 4. **Replay LRU short-circuit** — consult the per-sender-bucketed + * {@link ReplayLRU}. If we've recently processed this + * `(senderPubkey, bundleCid)` pair, return a `{replay: true}` + * sentinel instead of re-running §5.2 (idempotent per §5.6). The + * caller treats this as a no-op — the original processing's + * disposition stands. + * + * 5. **CAR import** — `UxfPackage.fromCar(carBytes)`. On any + * `UxfError` thrown by the import path (malformed envelope, + * missing manifest, ...) we surface as + * `BUNDLE_REJECTED_VERIFY_FAILED` because the acquirer's contract + * is "bundle's structure was unacceptable"; the verifier code path + * (#6 below) uses the same code for downstream `pkg.verify()` + * failures. + * + * 6. **Bundle verification** — delegate to {@link verifyBundleStructure}. + * On success, mark the LRU and return the {@link VerifiedBundle}. + * + * Design notes: + * + * - **LRU is marked AFTER successful verification, NOT on first + * arrival.** A bundle that fails §5.2 should NOT short-circuit a + * re-arriving valid bundle with the same `bundleCid` — the second + * arrival might be a different sender's republish or a corrected + * version.

Replay of the bytes + * under our key would re-execute the transition. + * + * The redaction layer (`core/errors.ts`) walks `cause` ONCE at construction + * time, deep-cloning it into a redacted view. Field names listed in + * `REDACTED_FIELDS` are replaced with an opaque marker. The original bytes + * are NOT retained on the error instance — the constructor's local + * reference goes out of scope as soon as it returns. + * + * Tested invariants: + * 1. `signedTransferTxBytes`, `signedCommitmentBytes`, `rawAuthenticator` + * are listed in the exported `REDACTED_FIELDS` constant. + * 2.

Arrays of redaction targets are redacted element-by-element. + * 6. Cycle-safe — a self-referential cause does NOT loop forever. + * 7. The exported `redactCause()` helper has the same behavior as the + * constructor's automatic redaction. + * 8.
