Subject: [PATCH 1/8] Goal sessions: goal-bound agent sessions behind a feature
 flag

People sign in as themselves (Google or GitHub; a test sign-in for local use),
belong to several workspaces, and work in pods with lead/member roles. Goals
are versioned and private, pod or workspace visible.

The local agent (packages/align-agent) meters Claude Code and Codex from their
own transcripts and rollouts. A user shares a session, or a whole folder
(align share --dir), and each shared session is bound to a goal by binding
epochs that change only at a prompt boundary. Hooks give the agent the goal
once, a short diff when it changes (at the next prompt or tool call), and
nothing on unchanged prompts. A stop from the web blocks the next tool call,
fail closed. There is no daemon and no telemetry setup: hooks start a short
one-pass sync that exits, and the Stop hook carries each turn's usage up.

Aligning a session to someone else's goal needs that owner's approval; an
approved "work toward" moves future usage and the session's directives to the
target goal, and revoking suspends the binding. Spend is reported per goal,
labelled as list-price estimates, with no per-person view.

v1 and Northstar are unchanged: every v2 route is 404 unless ALIGN_V2=1, and
the snapshot gate runs with v2 off and on. Wire contract: docs/v2/WIRE.md.

+# Align v2 wire contract (local agent ⇄ hosted server)
+
+Status: v2.1, 2026-10-22 (directive SSE stream removed; cursor polling only). Source of truth for both halves. Plan: `~/.claude/plans/no-we-need-a-logical-lark.md` (rev 2).
+Everything here is behind `ALIGN_V2=1`; with it unset every `/app*` and `/api/v2/*` path is 404.
+
+## Conventions
+- JSON only (`content-type: application/json`), UTF-8. Errors: `{ "error": "<code>", "message": "<human text>" }`.
+- Ids: `u_` user, `ws_` workspace, `pod_`, `g_` goal, `al_` alignment, `dv_` device, `dir_` directive, `ep_` epoch
+  (client-generated, 22+ url-safe chars). Random parts are base32/base64url, never sequential.
+- Times: ISO 8601 UTC strings. Money: integer micro-USD (`*_usd_micros`). Tokens: non-negative integers.
+- Device API auth: `Authorization: Bearer alnd_<opaque>` (access token, 1 h). Device routes reject cookies and any
+  request carrying an `Origin` header (browsers). Web routes use the Better Auth session cookie and reject Bearer.
+- Not visible to the caller → 404 (never 403). Visible but not allowed → 403 with a code.
+
+## Device pairing (RFC 8628 style, key-bound)
+The agent generates an Ed25519 keypair locally (`~/.align/device_key`, 0600; public key sent as base64url raw 32 bytes).
+
+`POST /api/v2/device/authorize` (no auth; 10/h per IP)
+→ req `{ "device_name": "Sean's MacBook", "public_key": "<b64url 32B>" }`
+→ 200 `{ "device_code": "<43+ chars>", "user_code": "BCDF-GHJK", "verification_uri": "<origin>/app/device", "expires_in": 600, "interval": 5 }`
+
+The user signs in at `/app/device`, types the code, sees device name + request age, ticks workspaces, approves.
+
+`POST /api/v2/device/token`
+→ req `{ "grant_type": "urn:ietf:params:oauth:grant-type:device_code", "device_code": "..." }`
+→ 400 `{ "error": "authorization_pending" | "slow_down" | "expired_token" | "access_denied" }`
+→ 200 (once) `{ "device_id": "dv_...", "access_token": "alnd_...", "expires_in": 3600, "refresh_token": "alnr_...", "user": { "id", "name", "email" } }`
+
+`POST /api/v2/device/refresh` (proof of possession; rotating; reuse of an old refresh token revokes the device)
+→ req `{ "device_id", "refresh_token", "ts": "<ISO>", "sig": "<b64url Ed25519 signature>" }`
+   signed message (UTF-8): `align-refresh\n<device_id>\n<sha256hex(refresh_token)>\n<ts>`; ts within ±5 min.
+→ 200 `{ "access_token", "expires_in": 3600, "refresh_token" }` · 401 `{ "error": "invalid_grant" }`
+
+`DELETE /api/v2/devices/self` (Bearer) → 204. Revokes this device's tokens (logout).
+
+## Identity and workspaces (device view)
+`GET /api/v2/me` (Bearer or cookie)
+→ `{ "user": { "id", "name", "email" }, "device": { "id", "name" } | null, "workspaces": [ { "id", "name", "role": "owner"|"member"|"viewer", "pods": [ { "id", "name", "role": "lead"|"member" } ] } ] }`
+Only workspaces the device was granted (device) or the user belongs to (cookie).
+
+## Goals feed
+`GET /api/v2/workspaces/:ws/goals` (Bearer; `If-None-Match` supported → 304)
+→ `{ "version": "<short hash>", "goals": [ Goal ] }` with header `ETag: "<version>"`.
+`Goal = { "id", "version": <int>, "title", "measures": [ { "id", "text", "target": string|null } ], "status": "active"|"achieved"|"dropped", "visibility": "private"|"pod"|"workspace", "owner": { "id", "name" }, "pod": { "id", "name" } | null, "anchors": { "repos": [string], "branch_patterns": [string], "issues": [string] }, "bindable": boolean }`
+The full set the caller may see (own private + pod + workspace). `bindable` = the caller may bind a session to it now
+(own goal, a goal of a pod they belong to, or a goal they hold an approved allocation transfer to). Anchors are
+matched locally by the agent only.
+
+## Shared sessions
+`session_key = base64url(HMAC-SHA256(device_secret, ws + "\0" + harness + "\0" + native_session_id))` (43 chars).
+`repo_key = base64url(HMAC-SHA256(device_secret, ws + "\0repo\0" + realpath(git toplevel or cwd)))`.
+
+`PUT /api/v2/workspaces/:ws/sessions/:session_key` (Bearer) — share or update
+→ req `{ "harness": "claude-code"|"codex", "repo_key", "repo_alias": string|null, "started_at", "title": string|null }`
+→ 200 `{ "session_key", "state": "shared"|"suspended", "current_epoch": Epoch|null }`
+Key owned by another user/device → 404.
+
+`POST /api/v2/workspaces/:ws/sessions/:session_key/epochs` (Bearer) — open a binding epoch
+→ req `{ "epoch_id": "ep_...", "goal_id": "g_..."|null, "starts_at": "<ISO>", "root_turn": string|null, "cause": "manual"|"directive:<dir_id>" }`
+→ 200 `Epoch = { "epoch_id", "goal_id", "goal_version_at_start", "starts_at", "ends_at": null }`
+   (closes the previous open epoch at `starts_at`). 403 `{ "error": "alignment_required" }` if the goal isn't bindable.
+   Epochs never overlap; a first share may open an epoch with `starts_at` = the session's start (counts from start).
+
+`POST /api/v2/workspaces/:ws/sessions/:session_key/usage` (Bearer) — idempotent batch, ≤500 rows, ≤256 KB
+→ req `{ "rows": [ UsageRow ] }`
+`UsageRow = { "request_key" (b64url HMAC of provider request id), "ts", "epoch_id", "model", "query_source": "main"|"subagent"|"auxiliary"|"unknown", "input", "output", "cache_read", "cache_write_5m", "cache_write_1h", "cache_write_unsplit", "basis": "api_usd"|"subscription_included"|"workspace_credits"|"estimated_list_usd"|"unknown", "est_list_usd_micros": int|null, "price_table_version", "source": "otel"|"transcript"|"rollout" }`
+→ 200 `{ "accepted": n, "duplicates": n, "conflicts": n }`. Same key with different values = conflict, never overwritten.
+Rows whose epoch is unknown or belongs to another session → rejected per row (counted as conflicts).
+
+`POST /api/v2/workspaces/:ws/sessions/:session_key/stop-sharing` (Bearer or cookie by owner) → 200; no more uploads accepted.
+`DELETE /api/v2/workspaces/:ws/sessions/:session_key` (Bearer or cookie by owner) → 204; hard-deletes session, epochs,
+usage, deliveries; rollups change (the UI says so).
+
+## Directives
+Only structured content reaches agents: ratified goal fields and enumerated states. Never alignment notes or counters.
+`Directive = { "id": "dir_...", "seq": <int>, "ws", "kind": "goal_version"|"binding_changed"|"binding_suspended"|"stop"|"resume", "session_keys": [string], "goal": Goal|null, "binding": { "goal_id", "effective": "next_root_turn", "cause": "alignment:<al_id>"|"manual" } | null, "created_at" }`
+- `goal_version`: a goal bound/governing for these sessions got a new version or status.
+- `binding_changed`: open a new epoch at the next root turn with `binding.goal_id` (approved allocation transfer).
+- `binding_suspended`: the current binding lost its authority (revoked alignment): stop uploading usage for the session
+  until the user picks a goal; the agent continues privately.
+- `stop` / `resume`: set / clear the local stop latch.
+
+`GET /api/v2/directives?cursor=<seq>` (Bearer) → `{ "directives": [Directive], "next_cursor": "<seq>" }` (≤100, this device's sessions only).
+There is no push channel: the local agent has no daemon, and each hook-started sync pass fetches by cursor.
+`POST /api/v2/directives/:id/receipts` (Bearer) → req `{ "session_key", "state": "received"|"applied"|"enforced", "at" }` → 200 `{ "fresh": bool }` (idempotent, ≤2 KB).
+
+## Spend
+`GET /api/v2/workspaces/:ws/spend?by=goal|pod|session&from&to` (cookie) → rows with token sums by basis and
+`est_list_usd_micros` sums (labelled estimates), plus `unallocated` and `unpriced_requests`. Invariant: total =
+Σ goals + unallocated. Private-goal spend visible to its owner only; others see it inside an unnamed "private" bucket.
+
+## Alignment (web, cookie)
+`POST /api/v2/workspaces/:ws/alignments` → req `{ "target_goal_id", "source_goal_id": string|null, "choice": "contribution"|"work_toward", "session_keys": [string], "note": string|null }`
+Effects: `contribution` → `contributes_to` only. `work_toward` → `contributes_to` + `governing_goal` + `allocation_transfer` for the listed sessions.
+Required approvers computed from effects and snapshotted on the revision. States: `pending` → `approved` | `rejected` |
+`withdrawn`; `countered` (new revision by an approver, e.g. fewer sessions) → requester `accept_counter` → `pending`.
+Actions: `POST .../alignments/:id/{approve|counter|accept_counter|reject|withdraw|revoke}` (approve carries `revision`).
+On approval with `allocation_transfer`: a `binding_changed` directive per session. Revoke is prospective; sessions whose
+binding exists only because of it get `binding_suspended`.
+
+## Changes (server)
+Implemented in `lib/v2/**` and `app/api/v2/**` (tests: `scripts/test-v2.mjs`). Everything above holds; these are the
+smallest additions and clarifications the server needed. Nothing here changes a field the agent already reads.
+
+Errors and credentials
+- Device routes: an `Origin` header is `403 browser_not_allowed`, a `Cookie` header `403 cookies_not_allowed`, a
+  missing/unknown/expired/revoked token `401 invalid_token`. Web routes: any `Authorization` header is
+  `403 bearer_not_allowed`; no session is `401 unauthorized`; a foreign `Origin` on a cookie write is `403 cross_site`.
+- `POST /device/token`: an unknown `device_code` is `400 invalid_grant`; a code that already returned 200 is
+  `400 expired_token` (single use). `slow_down` adds 5 s to the interval. `authorize` counts only well-formed requests
+  toward its 10/h limit.
+- `GET /workspaces/:ws/goals` also accepts the cookie (the web app reads the same feed).
+
+Sessions and epochs
+- `PUT` on a session after stop-sharing is `409 sharing_stopped` (stopping is sticky; re-sharing needs delete first).
+  So are epochs and usage. The same key with a different `harness` or `repo_key` is `409 session_conflict`.
+- Epochs: same `epoch_id` with the same values returns it (idempotent); with other values `409 epoch_conflict`.
+  `starts_at` before the open epoch's start or the last epoch's end is `409 epoch_overlap`; before the session's
+  `started_at` or more than 5 min in the future is `400`. A goal the caller can't see is `404`; a goal that isn't
+  `active` is `409 goal_not_active`. `cause: "directive:<id>"` must name a directive sent to this session (`400`).
+- `bindable` also requires `status: "active"`.
+- Binding a session to a goal other than its governing goal (manual) ends that governing goal.
+
+Directives
+- `binding_changed`: one directive per session; `goal` is the target Goal. `binding_suspended`: one directive listing
+  the affected sessions, `goal: null`, `binding = { goal_id: <goal that lost authority>, effective: "next_root_turn",
+  cause: "alignment:<al_id>" }`. On revoke the server ends that session's open epoch at the revocation time and sets
+  the session `suspended` (PUT then returns `state: "suspended", current_epoch: null`); usage rows for the ended epoch
+  are still accepted (in flight); opening an epoch on any bindable goal makes it `shared` again.
+- A directive's `goal` is the version ratified when it was written, plus `bindable` computed for the receiving user;
+  `goal` is `null` if that user can no longer see the goal.
+- Stop/resume are issued with `POST /api/v2/workspaces/:ws/sessions/:session_key/stop` and `.../resume` (cookie; the
+  session's owner or a workspace owner) → `{ directive_id, agent_stopped }`.
+
+Alignment (web)
+- Who may act: `approve` a required approver of the current revision, state `pending`, `revision` must equal the
+  current one (`409 stale_revision`); `counter` an approver who isn't the requester, state `pending`; `accept_counter`
+  the requester, state `countered`; `reject` an approver who isn't the requester (`pending` or `countered`);
+  `withdraw` the requester (`pending` or `countered`); `revoke` the requester or a current approver (`approved`).
+  Wrong state is `409 wrong_state`; wrong person `403`. Viewers can't act.
+- `counter` body: `{ revision?, choice?, keep?: [ref], session_keys?: [string], note? }`. A counter can only keep or
+  remove sessions; `ref` is `sessions[].ref` from the alignment view (approvers don't see other people's keys).
+- The author of a revision is counted as approving it when they are a required approver (the requester on revision 1,
+  the counterer on later ones); `accept_counter` records the requester's approval. A request whose approvers are all
+  satisfied at once (for example your own goal) is approved immediately.
+- One governing goal per session: requesting or approving `work_toward` for a session already governed by another
+  approved alignment is `409 already_governed` (revoke that one first).
+- `source_goal_id` must be a goal the requester may bind (own or pod), `403 source_not_yours` otherwise.
+- A goal the viewer can't see is shown as `{ id: null, title: null, visible: false }` and named "a goal you can't see".
+
+Spend
+- Response: `{ by, from, to, note, total: Sums, unallocated: Sums, unpriced_requests, rows: [ { key, kind, label,
+  goal?, pod?, session_key?, ...Sums } ] }` with `Sums = { requests, input, output, cache_read, cache_write_5m,
+  cache_write_1h, cache_write_unsplit, est_list_usd_micros, unpriced_requests, by_basis: { <basis>: same numbers } }`.
+- `kind`: `goal` | `pod` | `no_pod` | `session` | `others` | `private`. Every goal the caller can't see (others'
+  private goals, pod goals of pods they're not in) is in the one unnamed `private` row, in `by=goal` and `by=pod`.
+  `by=session` names only the caller's own sessions; everyone else's are one `others` row. `total = Σ rows +
+  unallocated` holds for every number in all three groupings. `from` inclusive, `to` exclusive, on request `ts`.
+
+Visibility
+- `pod` goals: the pod's members and workspace owners. `private`: the owner only (workspace owners included in "not").
+- Invite acceptance needs the signed-in email to equal the invited one; when hosted, the provider must have verified it.
+
+Web-only routes (cookie) added for the app: `GET/POST /api/v2/workspaces`, `GET /api/v2/workspaces/:ws`,
+`GET/POST .../invites`, `DELETE .../invites/:id`, `GET /api/v2/invites/:token`, `POST .../accept`, `POST .../pods`,
+`POST .../pods/:pod/members`, `DELETE .../pods/:pod/members/:user`, `POST .../goals`, `GET .../goals/:goal`,
+`POST .../goals/:goal/versions` (`{ version, title?, measures?, anchors?, status? }`, `409 stale_version` /
+`no_change`), `GET .../sessions`, `GET .../alignments`, `GET .../alignments/:id`, `GET /api/v2/device/requests/:code`,
+`POST /api/v2/device/approve` (`{ user_code, workspace_ids }`), `POST /api/v2/device/deny`, `GET /api/v2/devices`,
+`DELETE /api/v2/devices/:id`. Better Auth is mounted at `/api/v2/auth/*` (cookie `align_v2.session_token`,
+`__Secure-` prefixed when hosted).

+## Claude Code hooks
+
+Source: https://code.claude.com/docs/en/hooks (markdown at https://code.claude.com/docs/en/hooks.md)
+
+- Common input: `session_id`, `prompt_id` ("UUID for the user prompt being processed. Absent until the first user
+  input"), `transcript_path` ("written asynchronously and may lag the current turn"), `cwd`, `permission_mode`,
+  `hook_event_name`, and `agent_id`/`agent_type` inside subagents.
+- `SessionStart` input `source`: `startup`, `resume`, `clear`, `compact`, `fork`. Output
+  `hookSpecificOutput.additionalContext`.
+- `UserPromptSubmit`: input `prompt`. `decision: "block"` "stops the prompt before it reaches Claude"; `reason` is
+  "Shown to the user when decision is block. Not added to context." Plain stdout on exit 0 becomes context, so the hook
+  only ever prints JSON or nothing. The block message ends with `Original prompt:` and the text is still written to the
+  local transcript (it never reaches the model).
+- `PreToolUse`: `hookSpecificOutput.permissionDecision` in `allow | deny | ask | defer`; for deny,
+  `permissionDecisionReason` is "shown to Claude".
+- Exit codes: 0 applies JSON; 2 blocks; any other code is a non-blocking error and the action proceeds. A crashed hook
+  therefore fails open, so the latch path must print the deny JSON itself (it does, including on its own deadline).
+- `timeout` is in seconds (600 default; 30 on UserPromptSubmit). Align sets 5 and enforces 300 ms internally.
+- `additionalContext` and `systemMessage` are each capped at 10,000 characters (overflow goes to a file plus a
+  2,000-character preview). `systemMessage` is "a warning shown to the user". `suppressOutput` "has no effect".
+
+## Claude Code telemetry
+
+Source: https://code.claude.com/docs/en/monitoring-usage and the CHANGELOG at
+https://raw.githubusercontent.com/anthropics/claude-code/main/CHANGELOG.md
+
+- Env: `CLAUDE_CODE_ENABLE_TELEMETRY=1`; `OTEL_LOGS_EXPORTER` (`otlp|console|none`); `OTEL_EXPORTER_OTLP_LOGS_PROTOCOL`
+  (`grpc|http/json|http/protobuf`; "Claude Code has no default protocol"); `OTEL_EXPORTER_OTLP_LOGS_ENDPOINT` (example
+  `http://localhost:4318/v1/logs`); `OTEL_METRICS_EXPORTER=none` is valid; `OTEL_LOGS_EXPORT_INTERVAL` in ms, default
+  5000; `OTEL_LOG_USER_PROMPTS` "default: disabled"; `OTEL_LOG_TOOL_DETAILS` default disabled.
+- "Claude Code ignores the OpenTelemetry exporter variables in a repository's `.claude/settings.json`"; set them in
+  managed settings or `~/.claude/settings.json` `env`. Install therefore edits the user settings file.
+- `claude_code.api_request` attributes: `event.name` (`"api_request"`), `event.timestamp`, `model`, `cost_usd`,
+  `cost_usd_micros`, `duration_ms`, `input_tokens` ("excluding tokens read from or written to the prompt cache"),
+  `output_tokens`, `cache_read_tokens`, `cache_creation_tokens`, `request_id`, `client_request_id`, `speed`,
+  `query_source`, `effort`, `agent.name` and other attribution names. Events also carry `prompt.id`; `session.id` is a
+  standard attribute ("which `/clear` replaces").
+- CHANGELOG 2.1.300: "Added `cache_creation_5m_tokens` and `cache_creation_1h_tokens` to the OpenTelemetry
+  `api_request` event". The monitoring page's attribute list does not show them yet.
+- "Claude Code counts each streaming response toward the cost and token metrics exactly once"; retries are not logged
+  as separate events (`api_error` is terminal). "Cost metrics are approximations."
+- `request_id` is "persisted as `requestId` on the transcript's assistant entries" (documented as version-specific),
+  which is the cross-source dedupe key.
+- Standard attributes include `user.email` when signed in. The receiver drops it with everything else not allowlisted.
+
+## Codex hooks
+
+Source: https://learn.chatgpt.com/docs/hooks (markdown at https://learn.chatgpt.com/docs/hooks.md)
+
+- Locations include `~/.codex/hooks.json` and inline `[hooks]` in `~/.codex/config.toml`; both in one layer are merged
+  "and warns at startup". Install uses `hooks.json`.
+- Trust: "Codex records trust against the hook's current hash, so new or changed hooks are marked for review and
+  skipped until trusted." Review happens in `/hooks`. Align never writes trust entries.
+- Common input: `session_id` ("Subagent hooks use the parent session id"), `transcript_path`, `cwd`,
+  `hook_event_name`, `model`; turn-scoped events add `turn_id`.
+- `SessionStart` `source`: `startup|resume|clear|compact|fork`; `hookSpecificOutput.additionalContext` is developer
+  context. `UserPromptSubmit`: `turn_id`, `prompt`; block with `{ "decision": "block", "reason": ... }`.
+- `PreToolUse`: deny with `hookSpecificOutput.permissionDecision: "deny"` (legacy `decision: "block"` and exit 2 also
+  work). Returning `continue`, `stopReason` or `suppressOutput` there "marks that hook run as failed ... and continues
+  the tool call", so the hook never returns them. Hosted tools such as WebSearch do not pass through PreToolUse; the docs
+  say to "Treat tool hooks as a useful guardrail, not a complete enforcement boundary."
+- Model-visible hook output defaults to "roughly 2,500 tokens" (`additionalContextLimit`). `timeout` is seconds,
+  default 600. `matcher` `"*"` matches everything; UserPromptSubmit ignores matchers.
+- Background hooks: "Finishing a background hook doesn't start a new turn." Align uses no background hooks.
+
+## Codex telemetry
+
+Sources: https://learn.chatgpt.com/docs/config-file/config-reference.md, https://learn.chatgpt.com/docs/config-file/config-advanced.md
+(Observability and telemetry), and the emitter source at openai/codex `codex-rs/otel/src/events/session_telemetry.rs`
+(main branch, read through the GitHub API).
+
+- `[otel]`: `exporter = none | otlp-http | otlp-grpc`, `exporter.<id>.endpoint`, `exporter.<id>.protocol`
+  (`binary | json`), `log_user_prompt` ("Opt in to exporting raw user prompts"). `metrics_exporter` defaults to
+  `statsig`; Align does not touch it.
+- `codex.sse_event` carries "token counts on `response.completed`". In source the fields are `input_token_count`,
+  `output_token_count`, `cached_token_count`, `cache_write_token_count`, `reasoning_token_count`, `tool_token_count`,
+  plus common `conversation.id`, `model`, `auth_mode`, `user.email`. There is no response id and no turn id.
+
+## Local file shapes (read-only observation)
+
+- Codex rollouts (`~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl`): `token_usage_record.payload` has `thread_id`,
+  `turn_id`, `session_id`, `root_turn_id`, `response_id`, `usage{input_tokens, cached_input_tokens,
+  cache_write_input_tokens, output_tokens, reasoning_output_tokens, total_tokens}` and no model (the model comes from
+  `turn_context.payload.model`). `event_msg/token_count` repeats: one file had 824 token_count lines for 765 responses.
+  `session_meta.payload` has `id`, `session_id`, `parent_thread_id`, `source`, `thread_source`
+  (`user | subagent | guardian_review`); guardian threads run `codex-auto-review`. Across 78,161 records,
+  `cache_write_input_tokens` was always 0 and `total_tokens = input_tokens + output_tokens`.
+- Claude transcripts: user lines carry `promptId`; assistant lines carry `requestId` and repeat usage per content block.
+  950 of 1,255 requests had several finalized rows, never with differing usage. Subagent transcripts often never set
+  `stop_reason` (154 of 565 requests in 20 files), so unfinalized rows are billed from their last copy after 10 idle
+  minutes, as liminal-desktop does.
+- `~/.claude.json` has `oauthAccount` when signed in with a Claude account; `~/.codex/auth.json` has
+  `auth_mode: "chatgpt" | "apikey"`.
+
+## Where this contradicts or refines the plan or WIRE.md
+
+0. Metering is transcripts and rollouts only (decided 10-22): no OTel receiver, no telemetry settings written by
+   `align install`, no daemon. The OTel facts above are kept for reference. Hooks start a one-pass `align sync`
+   instead of feeding a long-running process.
+1. Codex OTel could not have been the primary meter anyway: `response.completed` has no response id, so it cannot be
+   deduplicated against rollouts. Codex is metered from rollout `token_usage_record` (keyed by `response_id`).
+2. `/clear` gives Claude a new `session.id`, so a per-session share does not carry across `/clear`. A folder rule
+   (`align share --dir`) covers it: the new session starts in the same folder and is shared from its start. Without a
+   rule the new session starts private and the hook shows a user-only hint.
+3. The stop latch covers every tool that passes through PreToolUse (Claude matcher `*`; Codex shell, apply_patch, MCP
+   and local function tools). Codex hosted tools are outside it, per the Codex docs. A stop issued from the web lands
+   at the first tool call after the next sync pass (at most about 30 s during an autonomous run).
+4. When a hook blocks a prompt (an `::align` command), Claude Code puts the original text back in the input box; the
+   user clears it with Ctrl+U before typing the next prompt.
+5. Transcript cache writes without the 5m/1h split stay `cache_write_unsplit` and unpriced instead of assuming a tier.

+# @liminal/align-agent
+
+The local half of Align v2: the `align` CLI, Claude Code and Codex hooks, and local metering from transcripts.
+There is no daemon and no telemetry setup. Hooks answer from local files and, at most every 10 to 30 seconds, start a
+short `align sync` in the background that makes one pass and exits.
+
+Provider traffic never passes through Align. Sessions are private until you share one, and only shared sessions ever
+reach the server. Wire contract: `docs/v2/WIRE.md`. Harness facts and sources: `HARNESS_FACTS.md`.
+
+Zero runtime dependencies (Node 24+: `node:sqlite`, `node:crypto`, `fetch`).
+
+## Commands
+
+```
+align login [--server <url>] [--name <device name>]   device flow; key-bound tokens
+align logout                                          revokes this device, wipes tokens and the device key
+align status                                          identity, last sync, hooks + hash, outbox, unpriced
+align sessions [--all] [--json]                       local sessions, tokens, basis, list-price estimate (offline)
+align goals [--workspace <name|id>] [--refresh]       cached goal feed
+align share --dir [folder] --workspace W --goal G     share every new session started in a folder (rule stays local)
+align share <session|--latest> [--cwd [dir]] --workspace W --goal <ref|none> [--alias <name>] [--from start|now] [--yes]
+align unshare --dir [folder] · align rules            remove a folder rule · list them
+align stop-sharing <session>                          future usage stays local
+align delete-history <session> [--yes]                server hard delete; totals change
+align bind <session> --goal <ref|none>                takes effect at the next prompt (root turn)
+align latch status                                    stop latches (stop/resume come from the web)
+align install [--claude] [--codex] [--dry-run]
+align uninstall [--purge]
+align sync                                            one pass: spool, transcripts, outbox, directives, upload
+align doctor                                          checks plus hook latency
+```
+
+In a session: `::align status`, `::align goals`, `::align share [--dir] [goal]` (then `... confirm`),
+`::align bind <goal>`, `::align unshare [--dir]`. These are answered locally and never reach the model.
+
+## How updates reach a session
+
+1. A hook fires (SessionStart always; UserPromptSubmit at most every 10 s; PreToolUse at most every 30 s) and starts
+   `align sync --hook` detached, then returns. The hook itself never touches the network.
+2. The sync pass reads new transcript lines, uploads usage for shared sessions, fetches new directives by cursor and
+   writes them to local files (`hot/`, `latch/`), then exits. A lock file keeps passes from overlapping.
+3. The next hook reads those files: a goal change goes into context at the next prompt as a short delta; a stop makes
+   the next tool call fail closed.
+
+So a goal change or stop issued from the web lands within one sync interval, at the next prompt or tool call.
+
+## What `align install` changes
+
+Copies the built `dist/` to `ALIGN_HOME/bin/<version>/` (adds a `package.json` with `"type": "module"`) and points the
+symlink `ALIGN_HOME/bin/current` at it, so hooks never run from a git checkout. Every edited file gets a
+`<file>.align-backup-<timestamp>` copy first, and `ALIGN_HOME/install.json` records what was added.
+
+- `--claude` (default when no flag is given): `$CLAUDE_CONFIG_DIR/settings.json` (default `~/.claude/settings.json`)
+  gets one handler each for `SessionStart`, `UserPromptSubmit` and `PreToolUse` (matcher `"*"`):
+  `'<node>' '<ALIGN_HOME>/bin/current/hook.js' claude <Event>`, timeout 5. Every other key and hook is kept;
+  re-running replaces Align's own handlers.
+- `--codex` (default when no flag is given): `$CODEX_HOME/hooks.json` (default `~/.codex/hooks.json`) gets the same
+  three events with `codex`. Codex lists new hooks for review; trust them in Codex `/hooks`. `config.toml` is not
+  edited.
+- `--dry-run` prints the plan and writes nothing. `align uninstall` removes only Align's handlers and keeps
+  `ALIGN_HOME` unless `--purge`.
+
+## State (`ALIGN_HOME`, default `~/.align`, 0700, must be owned by you)
+
+`config.json`, `credentials.json` (0600), `device_key` (Ed25519 PKCS#8, 0600), `device_secret` (32 random bytes,
+0600, never sent), `align.db` (SQLite WAL: sessions, root turns, epochs, request ledger, file offsets, outbox,
+directives, shares, aliases), `rules.json` folder share rules, `hot/` and `injected/` per-session JSON for hooks,
+`latch/` stop latches, `spool/` hook records for the next sync, `feeds/` cached goals, `me.json`, `last-sync.json`,
+`logs/`.
+
+Set `"default_workspace": "<ws id>"` in `config.json` if you belong to several workspaces and want `::align share`
+without `--dir`.
+
+## Privacy rules in code
+
+- Hooks read only local state, never the network, credentials or transcripts, and exit within 300 ms. The only
+  thing they start is the detached sync. A stop latch denies tools fail-closed, even if the sync never ran.
+- Uploads: session key and repo key are per-workspace HMACs; branch, paths and folder rules are never sent; titles
+  are sent as null. Only ratified goal fields reach the model, inside a fixed envelope (<= 1,200 chars) or delta
+  (<= 300 chars), and nothing at all when unchanged.
+
+## Development
+
+```
+npm install
+npm run build     # tsc -> dist/
+npm test          # build, then node --test test/*.test.ts (temp dirs and a localhost fake server only)
+```
+
+Every location is overridable for tests and dry runs: `HOME`, `ALIGN_HOME`, `CLAUDE_CONFIG_DIR`, `CODEX_HOME`,
+`ALIGN_SERVER`. `ALIGN_NO_AUTOSTART=1` stops hooks from starting syncs.

Subject: [PATCH 2/8] Goal sessions: the device secret fails closed instead of
 regenerating

deviceSecret wrote a fresh secret over the old one on any read error or a file
of the wrong length, which would silently change every session, repo and
request key and orphan sessions the device already shared. It now creates the
secret only when the file does not exist (exclusive create, so two first-run
processes cannot write different secrets) and otherwise refuses with a clear
message. Found by the pre-push review (f_2c5d0c1c5473).

Adds list-price rows for claude-sonnet-5-5 and claude-haiku-5-5. Haiku 5.5 has
two rate cards: prompts above 100K tokens (input plus cache read and write)
use the higher card. Price table version align-prices-2026-10-22.2.

Subject: [PATCH 4/8] Align agent: Claude Code plugin install, subagent-safe
 deltas, StopFailure sync

- align install now writes a skills-directory plugin for Claude Code
  (CLAUDE_CONFIG_DIR/skills/align) instead of merging hooks into
  settings.json. Claude Code loads it in every new session; `claude plugin
  disable align@skills-dir` turns it off; uninstall deletes the folder.
  Handlers an earlier Align merged into settings.json are removed (with a
  backup) so they do not run twice. Install refuses to replace a skills/align
  folder that is not Align's. Codex keeps the hooks.json merge.
- PreToolUse fires inside subagents too, and its context reaches only the
  subagent (checked with Claude Code 2.1.309). The mid-turn delta now skips
  calls with agent_id so the main agent still receives the goal change; the
  stop latch still applies in subagents.
- Parallel tool calls run their PreToolUse hooks at once. A lock directory
  lets exactly one of them deliver the delta.
- Claude Code runs StopFailure instead of Stop when a turn ends on an API
  error. It is now installed and starts the same end-of-turn sync, so that
  turn's usage uploads without waiting for the next prompt.

Agent suite 40/40; test-all 17/17 (Northstar identical with v2 off and on).
Two live tmux runs with hooks loaded only from the plugin: goal change
delivered 2/2, stop held 2/2, +0.6% prompt tokens vs no Align.

 - `timeout` is in seconds (600 default; 30 on UserPromptSubmit). Align sets 5 and enforces 300 ms internally.
 - `additionalContext` and `systemMessage` are each capped at 10,000 characters (overflow goes to a file plus a
   2,000-character preview). `systemMessage` is "a warning shown to the user". `suppressOutput` "has no effect".
+- Subagents: "When a subagent calls a tool, tool events such as `PreToolUse` and `PostToolUse` fire the same
+  configured hooks as in the main conversation", with `agent_id`/`agent_type` set. Context lands "at the point where the
+  hook fired". Checked with Claude Code 2.1.309 on 10-22: a marker returned from the subagent's PreToolUse appeared only
+  in `subagents/agent-<id>.jsonl`, never in the main transcript. So the mid-turn delta skips calls with `agent_id`
+  (the stop latch still applies there).
+- "When an event fires, Claude Code runs the matching hooks in parallel", and parallel tool calls each fire

+- `Stop` hooks "don't fire on user interrupts. API errors fire StopFailure instead." StopFailure's output and exit
+  code are ignored; Align uses it only to start the end-of-turn sync. Codex has no StopFailure.
+- A `Stop` hook that returns `additionalContext` or `decision: "block"` keeps the turn going, so Align's Stop prints
+  nothing.
+- Plugins: a folder in `~/.claude/skills/` "that contains a `.claude-plugin/plugin.json` is a skills-directory plugin"
+  that Claude Code "loads ... when a session starts, with no flag and no install step"; its `hooks/hooks.json` uses
+  the settings `hooks` shape. `claude plugin disable <name>@skills-dir` turns it off. Checked with 2.1.309:
+  `claude plugin list` shows `align@skills-dir` loaded and its hooks fire. A hook in both settings.json and a plugin
+  "runs twice", hence install removes older Align handlers from settings.json.

Subject: [PATCH 5/8] Goal sessions: goal tree and in-flight pod awareness

Server
- Approved alignments with a source goal make it a child (contributes_to).
  Children record the parent version they last reviewed and show as stale
  when the parent moves on; POST /goals/:goal/review confirms the fit.
- depends_on is a versioned goal field (at most 5).
- Activity feed: POST/GET /workspaces/:ws/activity. Edits, commits, task
  labels and claims, kept 24 h (claims 1 h), visible to readers of the
  session's goal. Paths and text only with work-signal consent; otherwise
  hashed repo and path ids.
- Goal page: tree card with stale pill and "Still fits", depends-on picker.

Agent
- Hooks log edits (including shell writes), reads, commit subjects and
  ::align task / ::align claim. The sync pass also detects git working-tree
  changes and new commits, uploads activity and fetches the pod feed.
- A card of at most 300 chars at prompt or session start, at most once per
  10 minutes unless work overlaps. A one-time hold for same-laptop edits to
  a file another session just changed; a note for cross-person overlap or
  claims. align pod and ::align pod show the detail.
- Parent and dependency changes arrive as one note naming the changed
  measure.

Tests: agent 49/49, test-v2 144/144, test-all 17/17.

+- A session's starting context also names the goal its goal contributes to (with its measures) and the goals it depends
+  on. A new version of either reaches every session under the child goal as one short note at its next prompt or tool

+  `::align task` and `::align claim` lines in `ALIGN_HOME/activity/<lid>.jsonl`. The sync pass uploads them (paths and
+  text only with `--signals`, otherwise keyed hashes) and caches other machines' activity in `feeds/activity-<ws>.json`.
+- At a prompt, a session gets one card (<= 300 chars) about work in flight toward its goal and related goals (parents,

+  person, overlap with its own files first. At most one card per 10 minutes unless work overlaps; 0 bytes when nothing
+  is new. `align pod` gives the agent more when it asks.
+- Edits are seen three ways: edit tools (Claude Edit/Write/MultiEdit, Codex apply_patch), plain shell writes (`>`,
+  `>>`, `tee`, `sed -i`, `cp`/`mv` targets, `git add` paths), and, in the sync pass, the repo's working tree and new

+- On this machine, an edit to a file another same-goal session changed in the last 20 minutes (and this session has not

Subject: [PATCH 6/8] Align agent: keep other people's free text out of model
 context

The pod card and cross-person notes put text from other machines into
agent context: names, task labels, commit subjects, claim reasons and
paths. Anyone in the pod could use those fields to steer another
person's agent.

- From other people the card and notes now carry only a first name
  (letters only) and paths made of path characters; overlap and note
  files use this session's own path for the file.
- Their task labels, commit subjects and claim reasons appear only in
  `align pod`, which marks quoted text as information, not instructions.
- This machine's own sessions are unchanged.
- The envelope invariant comment and README say what reaches the model.

Tests: agent 50/50 (new injection test), test-all 17/17.

Subject: [PATCH 7/8] Align agent: decide remote work by an explicit flag, not
 by a name

A summary from another machine with a blank account name was treated as
one of this machine's sessions, so its task label and commit subject
reached model context. Remote summaries now carry remote: true and the
card, the pod report and the quoted-text marker check that flag.

Tests: agent 50/50 (blank-name case added), test-all 17/17.

Subject: [PATCH 8/8] Goal sessions: hosted cookie writes need Origin exactly
 https://<Host>; rename the ALIGN_V2 flags

requireSameSite now matches lib/http.ts (LIM-2437): when hosted, Origin is required and must be exactly https://<Host>, so an http:// page, another port or a missing Origin is refused. The local rule is unchanged. The site check runs before the session lookup, so a cross-site write is refused without reading a session. test-v2 covers none, http, another port, null and foreign (403 cross_site) and the exact Origin (401 without a session).

ALIGN_V2 is now ALIGN_GOAL_SESSIONS and ALIGN_V2_TEST_IDP is ALIGN_GOAL_SESSIONS_TEST_IDP. Comments and docs no longer say Align v2.
