From 622921e0ef12352a1e2e6eef404d09c4807c76ea Mon Sep 17 00:00:00 2001 From: orveth Date: Thu, 16 Apr 2026 18:24:38 -0700 Subject: [PATCH 1/7] feat(core): nostr pool + NIP-87 parse + Layer A d-tag validator (PR #2) Adds two modules to @bitcoinmints/core with zero UI/storage/HTTP concerns: packages/core/src/nostr/ Thin SimplePool wrapper (nostr-tools 2.23.3). Exports: - SEED_RELAYS: [nos.lol, relay.damus.io, relay.primal.net] - createPool({ relays }) -> { subscribe, close } subscribe() dispatches one subscribeMany per filter and returns a handle with close(); events are forwarded with the first relay url seen via pool.seenOn. Caller's relay array is defensively copied. packages/core/src/nip87/ - dtag.ts: Layer A d-tag shape validator /^0[23][0-9a-f]{64}$/ (NUT-00 compressed secp256k1 pubkey). Rejects 972f233a... bot-spam (16-char ids) and pre-spec raw-pubkey (64-char) legacy emitters. Layer B (NUT-06 signer binding) is PR #4, not here. - parse.ts: parseMintAnnouncement (kind:38172 Cashu, kind:38173 Fedimint) + parseRecommendation (kind:38000). Rating parse order: canonical ["rating","","5"] -> legacy ["rating",""] -> content [N/5] regex -> undefined. JSON content tolerated. - types.ts: MintAnnouncement, MintRecommendation, network enum. Corpus: 16 real + synthetic events in __fixtures__/nip87-sample.json captured from live seed relays. Empirical finding documented in _meta.notes: NO 38172 in the real sample uses the spec-conforming 66-char d-tag; 5/8 are bot-spam and 1/8 is legacy 64-char shape. Two synthetic spec-conforming fixtures are included so Layer A has a positive case until real publishers adopt NUT-00 shape. Verified: bun run typecheck && bun run test green (52 tests, 5 files). biome clean on packages/ (root check has a NixOS binary-loading quirk; CI on Ubuntu is unaffected). Stacked on v2 (PR #27 merged). Cache is PR #3, Layer B is PR #4.

Events can race past handle.close() and land in the user callback after the caller believes the subscription is gone. Hoist the closed flag above the subscribeMany call so the onevent and oneose closures can read it. Gate the user-callback forward on !closed in both paths. Also flip closed=true in the closeOnEose branches so they don't double-fire and so subsequent late events are also dropped. Add a test that sends one event before close and one after, asserting only the pre-close event is delivered. Found in PR #28 review.

Empty filter array — subscribe({ filters: [], ... }) must be a no-op: zero subscribeMany calls, handle.close() safe and idempotent. Documents the wrapper's degenerate-input contract. 2. closeOnEose:true without onEose — exercises the "closeOnEose-only" oneose closure (different code path than the one with onEose set). Asserts the handle auto-closes on EOSE and that subsequent events are dropped via the post-close gate from the prior fix. 3. Multiple concurrent subscribes on the same pool — fires events into each subscription's onevent in turn and verifies isolation: each handle only sees its own events; closing handleA does not tear down handleB; post-close gating applies per-handle, not pool-wide. No production code change. All existing tests still pass.
