|---|---|
Evidence contracts and subject resolution src/lib/oc-evidence.ts, src/lib/evidence-hash.server.ts, src/lib/spx-subject.ts, src/lib/grade.ts, src/lib/grade.server.ts, src/lib/grade.test.ts |
Defines validated OC evidence inputs, event transitions, severity mapping, canonical JSON hashing, and normalized subject resolution. Grade code uses the shared resolver. |
Transactional lifecycle storage migrations/0006_oc_evidence.sql, src/lib/db.ts |
Adds lifecycle, immutable event, and pending outbox tables. Adds transaction support for Neon and PGLite, migration loading fallback, rollback handling, and nested-transaction rejection. |
Evidence emission and persistence src/lib/oc-evidence.server.ts, BUILD.md |
Creates and validates evidence, probes decoder status, fails closed when prerequisites are unavailable, classifies transitions, and persists advancing events and outbox rows atomically. Updates S2 and Hall status documentation. |
Behavior validation and test execution src/lib/oc-evidence.test.ts, scripts/run-tests.mjs, package.json |
Tests taxonomy, hashing, validation, transitions, duplicate handling, rollback, subject binding, and decoder gating. The test script discovers test files recursively before invoking Node’s test runner. |
Estimated code review effort: 4 (Complex) | ~45 minutes
Merge Risk: 🟡 Moderate · up to 88958
The PR adds durable fail-closed OC evidence handling, but its test runner currently uses a Node.js option unavailable in the supported Node.js 22.0.0 environment, causing the standard test command to fail before discovering tests. Merge should wait for that command to be corrected or for the owner to explicitly accept the limitation.

Poem
I’m a rabbit with evidence neat,
Hashes and subjects in rows complete.
The decoder must wake before gates swing wide,
Transactions keep each event inside.
Hop, hop—tests guard the flow with pride!

💡 Quality: classifyOcTransition mutates DB in a classification path
classifyOcTransition() inserts an oc_lifecycle placeholder row (on conflict do nothing), takes a for update lock, then deletes the row again when latest_event_id is null. A function that reads/classifies state thus performs writes and holds a per-contract row lock, adding write amplification and lock contention against concurrent persistOcEvidence() calls on the same contract. If a read-only classification is the intent, consider classifying from an existing row without inserting a placeholder (e.g. skip the insert and treat a missing row as the null-previous case), reserving the insert+lock for the persist path only.

Addressed in bcd3f7c. ocEvidenceInputSchema now refines the input so OC_FULFILLED requires capsule_id (path: capsule_id), matching FINAL_DESIGN.md's fulfillment-follows-Capsule semantics. Added a regression test covering rejection of capsule-less OC_FULFILLED and acceptance of capsule-less non-terminal events. Typecheck, 94/94 tests, format, and lint all pass.

Addressed in da92404. Added two DB-backed tests in src/lib/oc-evidence.test.ts:
OC persistence advances latest_event_id through opened, awarded, terminal— persists a full open → award → fulfill chain and assertsoc_lifecycle.latest_event_idfollows each advance and each event lands in bothoc_evidence_eventsandoc_evidence_outbox.OC persistence allows only one of two competing terminal events— racesOC_FULFILLEDvsOC_SLASHEDagainst the same awarded contract viaPromise.all, asserting exactly one terminal write advances, the loser is rejected without persisting, andlatest_event_idpoints at the winner.
Also fixed a pre-existing syntax error in src/lib/db.ts (a misplaced } put finally outside the try/catch), which was blocking every DB-backed test from loading. Full suite: 95/95 passing.

- The row-lock path is only exercised by sequential persistence tests, so the core contention guarantee is unverified. Add a concurrent test that starts from
OC_AWARDED, persists two different terminal events withPromise.all, and verifies that exactly one advances and only one terminal event/outbox row is committed. This is mandatory for the claimed one-terminal-event, retry-safe behavior.

- This reports
decoderLive: truewhen only the decoder probe is positive, even though the authenticated ingestion contract and canonical mapping are still unavailable. That contradicts the PR's “nodecoderLive: true” scope and BUILD.md's statement thatdecoderLiveremains false until all three prerequisites ship; because this flag is also documented as the Hire Hall gate, it can advertise readiness prematurely. Keep the gate false until end-to-end ingestion is ready, or expose decoder observation as a separate non-gating field.

- Resolving the subject from the current environment for every event still breaks an in-progress contract when the map rotates. After an
OC_OPENEDis persisted with the old subject, a newly createdOC_AWARDEDreceives the new subject and is classified asconflictby the subject-invariance check inoc-evidence.ts:105. The new mutation test only retries the already-materialized opening event, so it does not cover this path. Resolve from the map only for a new lifecycle; subsequent events need to be materialized against the subject stored for that contract under the lifecycle lock.

- A fresh event re-resolves the subject from mutable environment configuration. After an
OC_OPENEDevent is persisted, changing that map causes a newly createdOC_AWARDEDevent to carry a different subject, andclassifyOcTransitionFromStatereturnsconflict; the active contract can no longer advance. The new regression test only retries the already-materialized event, so it does not cover this path. Preserve the lifecycle's persisted subject binding when constructing later events.

What changed
handle/cluster-slugmapWhy
Complete the Flok-owned S2 Gate 1 boundary without opening Hire Hall or inventing an upstream ingestion contract. This reshapes the original definition-only slice into durable, retry-safe evidence that remains blocked from egress.
Verification
npm run typecheck— passednpm run lint— passed with 9 pre-existing Fast Refresh warningsnpm run build:ci— passedoc-evidence.test.tsnpm test— exits 0 but discovers 0 tests on PowerShell because package globs are single-quoted; expanded paths were run explicitlybash scripts/smoke.sh— blocked by CRLF parsing on Windows; normalized WSL retry could not reach the Windows-hosted serverRisk
Medium. The schema and transaction path are new and security-sensitive, but there is no public OC write route and no upstream egress. The emitter remains fail-closed even if a probe reports the decoder live.
Not changed
decoderLive: trueBUILD phase: S2 Gate 1
Note
Medium Risk
Adds a new contract-lifecycle schema and transactional row-lock path for evidence identity, but there is no public write route and emission stays fail-closed with no upstream egress.
Overview
Completes S2 Gate 1 by turning OC evidence from a definition-only slice into durable, retry-safe
flok.oc-evidence.v1records. Subjects, event IDs, andsha256:hashes are computed server-side; callers cannot supply those trust fields.Lifecycle is classified under a per-contract row lock (
OC_OPENED→OC_AWARDED→ one terminal event). Advances append the event and outbox row in one transaction; retries are duplicates.emitOcEvidenceprobes fail-closed and never fetches an ingestion endpoint, so Hire Hall stays closed until the upstream decoder contract exists.Also adds
Sql.transactionfor Neon and PGLite, a Windows-safe test runner, and tighterhandle/cluster-slugsubject-map validation.Reviewed by Cursor Bugbot for commit 9cdeb5d. Configure here.
