From e8c3f4d0264b142ac265c60a9d90f5826fb93ab7 Mon Sep 17 00:00:00 2001 From: Matt Kane Date: Sat, 9 May 2026 23:05:36 +0100 Subject: [PATCH 1/8] feat(aggregator): DID resolver with known_publishers cache MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit First piece of the records-consumer slice. Schema additions to 0001_init.sql (still pre-deploy, no follow-up migration needed): - publishers + publisher_verifications for the publisher.* NSIDs - dead_letters for verification-failure forensics (distinct from the configured Cloudflare DLQ, which is for transient retry exhaustion — different failure modes, different destinations) - signing_key / signing_key_id columns on known_publishers so the table doubles as the DID-doc resolution cache; 24h TTL applied at query time WANTED_COLLECTIONS extended with publisher.profile and publisher.verification. DidResolver: pure constructor-injected class with a DidDocCache interface (Map-backed in tests, known_publishers-backed in prod via createD1DidDocCache). Materialises cached multibase keys to PublicKey instances via @atcute/crypto, exhaustive on the p256/secp256k1 discriminated union. invalidate() for the re-resolve-after-key-rotation path the verification step needs. 14 tests covering cache hit/miss/expiry/invalidate, malformed-DID rejection, missing PDS / missing #atproto verification method rejection, and the D1 binding contract (round-trip, first_seen_at preserved across updates, end-to-end with the resolver). --- apps/aggregator/migrations/0001_init.sql | 96 ++++++- apps/aggregator/package.json | 1 + apps/aggregator/src/constants.ts | 12 + apps/aggregator/src/did-resolver.ts | 218 +++++++++++++++ apps/aggregator/test/did-resolver.test.ts | 322 ++++++++++++++++++++++ pnpm-lock.yaml | 6 + pnpm-workspace.yaml | 1 + 7 files changed, 655 insertions(+), 1 deletion(-) create mode 100644 apps/aggregator/src/did-resolver.ts create mode 100644 apps/aggregator/test/did-resolver.test.ts diff --git a/apps/aggregator/migrations/0001_init.sql b/apps/aggregator/migrations/0001_init.sql index 251ea002bc..11b54fcf32 100644 --- a/apps/aggregator/migrations/0001_init.sql +++ b/apps/aggregator/migrations/0001_init.sql @@ -78,6 +78,59 @@ CREATE TABLE release_duplicate_attempts ( CREATE INDEX idx_release_duplicates ON release_duplicate_attempts(did, package, version); +------------------------------------------------------------------------------ +-- Publishers: identity-level publisher profiles + verification claims +------------------------------------------------------------------------------ + +-- One row per publisher DID (rkey is always literal `self`).

charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the no-op queue() handler in index.ts with the full verification + ingest pipeline for the four record collections in scope (package.profile, package.release, publisher.profile, publisher.verification). Per-job pipeline: 1. Resolve PDS endpoint + signing key via DidResolver (cached in known_publishers, 24h TTL). 2. Fetch CAR via com.atproto.sync.getRecord, hand to @atcute/repo's verifyRecord (MST + signature in one call), capture carBytes for record_blob storage. 3. Cross-check verified vs Jetstream-supplied bytes; verified always wins; mismatch logs as `[aggregator] jetstream-discrepancy` for future Jetstream-correctness monitoring. 4. Lexicon-validate via @atcute/lexicons safeParse against the schema from @emdash-cms/registry-lexicons. 5. Per-collection structural checks: - package.profile: record.id must equal at://did/collection/rkey (the publisher could lie in the body even though MST verifies); slug optional, falls back to rkey, must match rkey if present - package.release: rkey must equal `:`, version must parse as semver, version_sort computed from a 10-digit zero-padded major.minor.patch + prerelease fragment - publisher.profile: rkey must be 'self'; contact entries must have at least one of url/email (lexicon can't express that constraint) - publisher.verification: facts stored as observed; validity check (current handle/displayName matches bound values) is read-time 6. Write to D1 with upserts on the appropriate primary key. Releases use INSERT … DO NOTHING; on a different-content same-version retry, audit a release_duplicate_attempts row with reason IMMUTABLE_VERSION. Delete handling: - Hard-delete for one-per-DID rows (package.profile, publisher.profile) - Soft-delete (tombstoned_at) for everything else - 0001_init.sql: releases FK now ON DELETE CASCADE so an out-of-order delete (publisher deletes profile before releases drain) doesn't get blocked by FK violation; the publisher's intent is the whole package going away Error policy: - PDS network/timeout/5xx: message.retry() - 404, oversized response, signature/MST/lexicon failure, structural failure: write dead_letters row with structured reason + payload, message.ack(). Never retry — these are malicious or broken upstream and we know retrying won't help - Unexpected programming errors: log loud, dead-letters, ack — never crash the worker (would block the queue slot) Test coverage (37 new tests, 65 aggregator tests total): - Per-collection writers: insert, upsert, lexicon failure, structural rejection (RKEY_MISMATCH, CONTACT_VALIDATION_FAILED, INVALID_VERSION) - Releases: version_sort computation; same-content replay is silent; different-content replay audits release_duplicate_attempts - Delete: hard-delete vs tombstone per collection; verification upsert clears tombstone (re-publish recovers) - Dispatcher: ack on success, retry on transient PDS error, retry on network error, ack+dead_letters on permanent PDS error, delete short-circuits PDS fetch Known gaps (deferred): - End-to-end happy-path test using FakePublisher + MockPds requires a node-pool vitest project; left for a follow-up. Each layer is independently tested; the wiring between them is the gap. - releases.cts column mirrors verified_at because the lexicon doesn't expose a creation timestamp and verifyRecord doesn't surface the commit rev. Tracked in the writer with a TODO. - Slice 3 artifact-mirror enqueue is a TODO comment in the release writer; mirrored_artifacts stays empty for now. --- apps/aggregator/migrations/0001_init.sql | 11 +- apps/aggregator/src/did-resolver.ts | 8 +- apps/aggregator/src/index.ts | 5 +- apps/aggregator/src/pds-verify.ts | 225 ++++++ apps/aggregator/src/records-consumer.ts | 700 ++++++++++++++++++ apps/aggregator/test/pds-verify.test.ts | 175 +++++ apps/aggregator/test/records-consumer.test.ts | 638 ++++++++++++++++ 7 files changed, 1757 insertions(+), 5 deletions(-) create mode 100644 apps/aggregator/src/pds-verify.ts create mode 100644 apps/aggregator/src/records-consumer.ts create mode 100644 apps/aggregator/test/pds-verify.test.ts create mode 100644 apps/aggregator/test/records-consumer.test.ts diff --git a/apps/aggregator/migrations/0001_init.sql b/apps/aggregator/migrations/0001_init.sql index 11b54fcf32..07ad4436a1 100644 --- a/apps/aggregator/migrations/0001_init.sql +++ b/apps/aggregator/migrations/0001_init.sql @@ -58,7 +58,16 @@ CREATE TABLE releases ( verified_at TEXT NOT NULL, tombstoned_at TEXT, -- soft delete (publisher deleted record) PRIMARY KEY (did, package, version), - FOREIGN KEY (did, package) REFERENCES packages(did, slug) + -- ON DELETE CASCADE because Jetstream events for a publisher can arrive + -- in arbitrary order under network reorder.

Per-finding rationale: BLOCKERS / CORRECTNESS - B1: refreshPackageLatest() recomputes packages.latest_version + capabilities after release insert / un-tombstone / tombstone-on-delete. Before: profile writer bound `null` for both columns with a comment promising the release writer would populate them; release writer never did. Read APIs that read latest_version got NULL forever. - B2: same-content release on a tombstoned row clears tombstoned_at instead of silently no-op'ing through DO NOTHING. Otherwise a delete-then-republish-same-content round-trip leaves the release invisible to readers with no audit row to explain why. - B3: release.extensions field is now validated as a plain object containing a releaseExtension-keyed entry that passes PackageReleaseExtension.mainSchema. emdash_extension column stores only the validated payload (not arbitrary record.extensions). Previously the consumer wrote whatever the publisher sent, including scalars like "lol" — read API parsing would have thrown. - M1: package.profile.security[] entries enforce "at least one of url|email" per lexicon. Was only enforced for publisher.profile. - Mi7: release writer pre-checks parent profile existence and throws the new MissingDependencyError → controller.retry() instead of letting the FK violation bubble up as UNEXPECTED_ERROR with no recovery path. Out-of-order Jetstream delivery (release event before its profile event) now retries until the profile arrives or hits max_retries → DLQ for the reconciliation pass. SHOULD-FIX / SAFETY - M3: version_sort rejects components or prerelease numerics longer than 10 digits as INVALID_VERSION (the pad-width ceiling). - M5/M6/N1: mapPdsReason parameter typed via the imported VerificationFailureReason union so a new reason added in pds-verify.ts becomes a compile-time error here. PDS_NETWORK_ERROR (the unreachable transient case) now throws "unreachable" instead of silently dead-lettering as UNEXPECTED_ERROR. Exhaustive `never` default catches future variants. - M9: removed JSON.stringify discrepancy comparison between Jetstream copy and verified PDS copy. The verified copy always wins so the comparison is a monitoring signal only, but JSON.stringify isn't canonical (key order, undefined-vs-missing) so it would fire false-positive warnings constantly in real traffic. Add a CBOR-canonical comparator when this monitoring becomes load-bearing. - M2 (piggybacked): applyDelete for releases parses rkey to use the PK index instead of the partial idx_releases_latest seek-then-scan. - Mi5: applyDelete for unknown collections throws IngestError UNKNOWN_COLLECTION instead of silently warning + acking. The dispatcher's delete branch catches IngestError → forensics + ack so unknown collections land in dead_letters instead of disappearing. - Mi6: record.package field validated against the package-slug regex (`^[a-zA-Z][a-zA-Z0-9_-]*$`). Closes the ambiguous-rkey hole where package="foo:bar" + version="1.0.0" produced the same rkey as package="foo" + version="bar:1.0.0". - B4: processBatch accepts an optional depsOverride parameter for testability. Production wiring path is now unit-test reachable. LINT / CODE QUALITY - jetstream-client.ts: replaced `event as unknown as JetstreamCommitEvent` with a type-predicate `isCommitEvent` so the narrowing is explicit. Same runtime semantics. - records-do.ts: dropped redundant `` type argument on `extends DurableObject` — `Cloudflare.Env` is the default. - records-consumer.ts: introduced isPlainObject() type guard; dropped redundant constructor on MissingDependencyError. REVIEW FINDINGS NOT FIXED - M4 (DID syntax allowing underscore): phantom finding. The original regex already allowed `_` everywhere — the reviewer misread the character class. Verified via xxd. No-op change reverted. - M7 (cache invalidate race): not load-bearing under serial dispatch. Documented for the eventual parallel-dispatcher follow-up. - M8 (release_duplicate_attempts noise during retry windows): observe first; the proposed mitigation (skip audit if verified_at younger than 10min) adds complexity that may itself be wrong. - Mi1, Mi2, N2, N3: cosmetic. 83 aggregator tests pass (was 65).

Per-finding rationale: HIGH - #1: refreshPackageLatest TOCTOU race. Two concurrent consumer invocations could each SELECT max version_sort, then race their UPDATEs, leaving packages.latest_version regressed (final write wins from the older snapshot). Replaced the SELECT-then-UPDATE pair with a single UPDATE using correlated subqueries; D1 serialises the read+write at write-commit time, so concurrent callers always compute against the actual current state. Capabilities now extracted via SQLite's json1 functions (json_each + json_group_array on $.declaredAccess). - #2: stale latest_version on refresh failure. INSERT committed, refresh threw, dispatcher acked → permanent inconsistency because subsequent same-content retries hit DO NOTHING and the prior conditional-only refresh skipped. Now insert + refresh run in db.batch() — D1 wraps in one transaction, so either both commit or both roll back. Same fix in applyDelete (tombstone + refresh batched). Refresh runs unconditionally on every release ingest path (idempotent; race-safe via #1). MEDIUM - #3: mapPdsReason throw escaped the catch. Function-arg evaluation ran mapPdsReason(err.reason) BEFORE writeDeadLetter, so a throw there crashed the whole batch. Now wrapped in its own try/catch with an UNEXPECTED_ERROR fallback so the dead_letters write still happens. - #4: isCommitEvent predicate trusted `kind` only. A producer emitting `{kind: "commit"}` without a structurally valid `commit` field would slip through and crash the ingestor at `event.commit.collection`; cursor wouldn't advance, Jetstream would replay the malformed event forever. Predicate now verifies commit.collection / commit.rkey / commit.operation are present strings. Test stub updated to match what real producers emit. - #5: parseReleaseRkey URIError on malformed %-encoding. A delete with rkey "demo:1.0.0%XX" threw URIError → not caught as IngestError → controller.retry() → 5 wasted attempts before DLQ. Now caught and returned as null so applyDelete silently no-ops. - #6: DLQ had no consumer. Configured a second consumer in wrangler.jsonc draining `emdash-aggregator-records-dlq`. New drainDeadLetterBatch handler logs each job to Workers logs + writes a `dead_letters` forensics row, then acks. Until reconciliation lands, this prevents permanent silent drops of legitimate-but-out-of-order release events that exhausted retries. - #7: release_duplicate_attempts unbounded under spam. Hostile publisher pumping the same different-content payload could fill the audit table indefinitely. Added UNIQUE(did, package, version, attempted_record_blob) constraint + ON CONFLICT DO NOTHING on the insert, so true duplicates dedupe at the storage layer. LOW - #8: previously-claimed "MissingDependencyError retry" test actually only exercised the PDS_HTTP_ERROR(5xx) path. Added a proper test using the new ConsumerDeps.verify injection point — exercises the writer's parent-profile pre-check and asserts the dispatcher routes MissingDependencyError → controller.retry(). WIRING / TESTABILITY - ConsumerDeps gained an optional `verify` override, defaulting to fetchAndVerifyRecord. Tests can inject a stub that returns a synthetic VerifiedPdsRecord without standing up a real CAR fixture. This is what makes the MissingDependencyError test reachable inside the workers pool. - index.ts queue() handler now dispatches by batch.queue name to either processBatch (records) or drainDeadLetterBatch (DLQ). LINT CLEANUP - jetstream-client.ts: defined a wider `MaybeCommitEvent` parameter type for the predicate so commit-field inspection doesn't need an unsafe cast. The type's `commit?` is structurally-typed so any RawJetstreamSubscription with E extends {kind: string} remains assignable. - records-consumer.ts: removed unused refreshPackageLatest wrapper; callers use refreshPackageLatestStmt directly inside batches. 89 tests pass (was 83). Typecheck clean. Zero lint diagnostics in apps/aggregator. Reviewer's verdicts on round-1 fixes I claimed: all present and structurally correct. The new bugs were byproducts, not regressions. --- apps/aggregator/migrations/0001_init.sql | 9 +- apps/aggregator/src/index.ts | 19 +- apps/aggregator/src/jetstream-client.ts | 36 ++- apps/aggregator/src/records-consumer.ts | 234 +++++++++----- apps/aggregator/test/jetstream-client.test.ts | 13 +- apps/aggregator/test/records-consumer.test.ts | 289 ++++++++++++++++-- apps/aggregator/wrangler.jsonc | 12 + 7 files changed, 498 insertions(+), 114 deletions(-) diff --git a/apps/aggregator/migrations/0001_init.sql b/apps/aggregator/migrations/0001_init.sql index 07ad4436a1..ad2ef96ecd 100644 --- a/apps/aggregator/migrations/0001_init.sql +++ b/apps/aggregator/migrations/0001_init.sql @@ -76,13 +76,20 @@ CREATE INDEX idx_releases_cts ON releases(cts); -- Audit trail for rejected duplicate-version attempts.

Per-finding rationale: MEDIUM - #1: drainDeadLetterBatch silently dropped messages on D1 failure. The try/catch around writeDeadLetter swallowed errors, then the unconditional message.ack() outside the try acked anyway — forensics lost AND message gone. The configured max_retries: 3 in wrangler.jsonc was dead config because the handler never threw. Fix: move ack() inside the try; on error, controller.retry() so workerd redelivers per the DLQ consumer's max_retries. - #2: FTS thrashing on idempotent refresh. Round-2 traded releaseSetChanged guard for "always run refresh" to fix the insert-success / refresh-failure consistency bug. But the unconditional refresh hit the packages_au AFTER UPDATE trigger, which DELETEs and re-INSERTs into packages_fts on every row touch — even when latest_version + capabilities are unchanged. Every same-content Jetstream replay (the common case) reindexed FTS for no reason. Fix: extend REFRESH_PACKAGE_LATEST_SQL's WHERE clause to short-circuit at SQL level when both target columns already hold the computed values. Avoids the trigger fire entirely; keeps the round-2 atomicity (insert + refresh still in one batch). MINOR - #3: applyDelete malformed rkey was a silent no-op. Round-2 fix correctly stopped the URIError-causes-retry path but overcorrected by removing the audit trail. Operators investigating "why didn't this delete take effect?" had nothing to look at. Now throws IngestError("RKEY_MISMATCH") so the dispatcher writes a dead_letters row before acking. - #4: release_duplicate_attempts.rejected_at was frozen at first attempt. Hostile publisher pumping the same bytes for a year showed in the audit table as a single row dated a year ago. Conflict clause now DO UPDATE SET rejected_at = excluded.rejected_at so the audit row tracks the latest attempt; same-bytes deduping at the storage layer still works. - #5: idx_release_duplicates was redundant with the new UNIQUE constraint's implicit index (the UNIQUE on (did, package, version, attempted_record_blob) covers all (did, package, version) prefix lookups). Dropped the explicit index — fewer indexes to maintain on each write. ASKED-ABOUT, NO BUG FOUND Reviewer verified all 12 prompt concerns either lead to fixes above or are clean: D1 batch atomicity, correlated-subquery semantics under SQLite snapshot isolation, json_each(NULL) behavior, MaybeCommitEvent parameter assignability, ConsumerDeps.verify injection correctness, duplicate dead_letters writes, jetstream-client test stub fidelity, concurrent dead_letters writes. No round-1 or round-2 finding regressed. 92 tests pass (was 89). Typecheck clean. Zero lint diagnostics in apps/aggregator. The slice has now had three rounds of adversarial review with all findings addressed in-tree.

One real bug + four doc/comment fixes + one test cleanup + one cosmetic. REAL BUG - json_group_array(key) over json_each enumerates in unspecified order, so the capabilities JSON string could vary between runs even when the key set is unchanged — defeating the WHERE-AND-IS-NOT short-circuit and re-firing the packages_au trigger on every idempotent refresh. Wrapped both subqueries in `(SELECT key FROM json_each(...) ORDER BY key)` so the resulting array is order-stable. DOC FIXES - pds-verify.ts 404 comment claimed "ack without forensics", but the consumer writes a dead_letters row for RECORD_NOT_FOUND (and tests assert that behavior). Updated comment to match the implemented policy: forensics for both the legitimate-race case and the programming-error case, distinguished by reason code for queryability. - parseReleaseRkey docstring claimed "callers should treat null as no-op", but applyDelete now throws IngestError on null to surface the malformed delete in dead_letters. Updated docstring to describe the actual contract. - dead_letters table comment listed reason values that don't match the implemented `DeadLetterReason` union. Replaced with the actual list and noted the union lives in records-consumer.ts. Also clarified payload is UTF-8 JSON bytes, not raw record bytes. - wrangler.jsonc DLQ-consumer comment claimed "repeated failures get acked after retries". Actual behavior: handler calls retry() on D1 failure, max_retries: 3 then workerd drops (no DLQ-of-DLQ). TEST CLEANUP - Removed an empty placeholder test that documented why the dispatcher's retry-on-MissingDependency wasn't covered. The proper coverage now exists in the dispatcher suite via ConsumerDeps.verify injection; the placeholder was dead. - Stripped review-finding shorthand codes (Mi6, B3, round-3 #1, etc.) from describe-block names.

Two real bugs + two doc fixes. REAL BUGS - DidResolver.invalidate() bumped known_publishers.last_seen_at backwards to 1970-01-01. The implementation called cache.upsert() with `new Date(0)`, and the D1 binding writes the same timestamp to all three of `pds_resolved_at`, `first_seen_at`, and `last_seen_at`. Net effect: invalidating a publisher's cached signing key (after a key rotation) corrupted the membership/observation timestamps as a side-effect. Fix: added a dedicated `expire(did)` method to the DidDocCache interface. The D1 binding's expire only touches `pds_resolved_at` (sets to epoch); the Map-backed test cache does the same in-memory. Resolver's `invalidate()` delegates to `cache.expire()` instead of forcing the issue through `upsert()`. - isCommitEvent didn't validate `commit.cid`. The ingestor reads `event.commit.cid` for non-delete operations, so a malformed commit event with no cid would slip through and produce a RecordsJob with `cid: undefined` — which the consumer would then try to verify against, with no useful error path. Fix: extended the predicate to require `cid` to be a string when `operation !== "delete"`. Delete events legitimately have no cid so the check is conditional. Test stub updated to match. DOC FIXES - applyDelete comment for package.profile claimed "we don't cascade because doing so silently throws away publication history". The schema FK has been ON DELETE CASCADE since the round-1 fixes (so out-of-order Jetstream delivery doesn't fail with FK violation when a profile-delete arrives before its release-deletes). Updated the comment to describe the actual cascade behavior + the audit history that DOES survive (release_duplicate_attempts, dead_letters). - release_duplicate_attempts schema comment said the consumer used `ON CONFLICT … DO NOTHING`, but the round-3 fix changed it to `DO UPDATE SET rejected_at = excluded.rejected_at` so operators can read freshness from the audit row. Updated the comment. 95 tests pass (was 91; added 2 jetstream-client cid-validation tests + 2 did-resolver expire tests). Typecheck clean.

charset=UTF-8 Content-Transfer-Encoding: 8bit ask-bonk + Copilot caught 5 real bugs and 1 stale comment. REAL BUGS - Duplicate-version detection compared raw CAR bytes. CARs include the publisher's commit + MST proof, which churns whenever the publisher writes any other record in the same repo — so a benign re-fetch of an unchanged record produced different bytes and got misclassified as an immutability violation. Fix: compare the verified record CID instead. CIDs are content-addressed and stable for unchanged records. Schema updated: `release_duplicate_attempts` gained `attempted_cid TEXT NOT NULL` and the UNIQUE constraint now uses it instead of `attempted_record_blob`. The blob is still kept for forensics so operators can inspect what was actually attempted; the conflict clause refreshes both `rejected_at` and `attempted_record_blob` so the latest envelope wins. Comparison logic in the writer reads the existing CID out of `signature_metadata` JSON via a small `parseCid` helper. - `processBatch` for-loop didn't isolate per-message failures. A `writeDeadLetter` throw inside `processMessage` (e.g. transient D1 hiccup mid-batch) escaped to the loop and halted it, leaving subsequent messages without ack/retry. With max_batch_size 25, one D1 hiccup could waste up to 24 PDS verification round-trips on redelivery. Now each message is wrapped in try/catch with a retry() on uncaught throw, matching the shape `drainDeadLetterBatch` already uses. - `computeVersionSort`'s `.zzz` final-release sentinel didn't actually beat all valid prereleases — `1.0.0-zzzz` sorts AFTER `1.0.0` because `"zzzz"` is lexically greater than `"zzz"`. Switched the sentinel to `~` (ASCII 126), one above the prerelease alphabet's max char (`z` at 122). Final releases now sort after any prerelease at the same major.minor.patch. - `parseReleaseRkey` validated nothing about its components — a malformed rkey like `demo:1.0.0:extra` parsed as `pkg=demo`, `version=1.0.0:extra`, then UPDATE matched no row and silently acked. Now validates pkg with PACKAGE_SLUG_RE and version with SEMVER_RE; returns null on mismatch so applyDelete throws IngestError → forensics row. - `isCommitEvent` accepted any string for `commit.operation`. An unknown operation slipping through would produce a RecordsJob the consumer can't dispatch on — landing as UNEXPECTED_ERROR in dead_letters. Now restricts to {create, update, delete}. DOC FIX - pds-verify.test.ts header claimed end-to-end coverage of the `verifyRecord` handoff exists in records-consumer.test.ts via MockPds + FakePublisher. Actually it's stubbed via ConsumerDeps.verify — the fixture can't load in the workers test pool. Updated comment to explain the actual coverage shape. 102 tests pass (was 95). Typecheck clean.
