📝 Summary

  • Add durable local quarantine metadata for irreparable sync_mutations rows while preserving the original journal evidence.
  • Exclude quarantined rows from transport and expose an explicit doctor repair dry-run/apply flow without fabricating cloud ACKs.

📂 Changes

File Change
internal/store/store.go Add additive migration, quarantine transition, transport filtering, and ACK safeguards.
internal/store/diagnostic.go Keep quarantined disposition metadata visible to administrative diagnostics.
cmd/engram/doctor.go Support local sync_mutation_required_fields dry-run/apply recovery.
internal/store/store_test.go Cover audit preservation, FIFO progress, idempotency, ACK invariants, and fail-closed persistence.
internal/store/store_migration_test.go Verify additive disposition columns.
cmd/engram/doctor_test.go Cover CLI dry-run/apply behavior and validation.

🧪 Test Plan

  • Focused store quarantine and migration tests pass.
  • go test ./internal/diagnostic ./internal/cloud/autosync
  • Focused cmd/engram doctor repair tests pass.
  • git diff --check
  • Full go test ./...: not claimed; existing Windows SQLite TempDir cleanup failures remain in internal/store.
  • E2E server tests: not applicable to this local store/doctor change.

📝 Walkthrough

Walkthrough

The PR adds disposition metadata to sync mutations, quarantines irreparable entries without deleting or acknowledging them, excludes quarantined entries from pending workflows, and exposes dry-run and apply behavior through engram doctor repair.

Changes

Sync mutation repair

Layer / File(s) Summary
Disposition schema and mutation data
internal/store/store.go, internal/store/diagnostic.go, internal/store/store_migration_test.go
sync_mutations gains disposition and audit fields. Queries scan the fields and identify pending rows. Migration tests assert the expanded schema.
Quarantine and pending lifecycle
internal/store/store.go, internal/store/store_test.go
The store reports or quarantines irreparable mutations. Quarantined rows remain in the journal, preserve payload and audit evidence, and no longer participate in pending transport, acknowledgment, counting, or sync lifecycle state. Tests cover idempotence and rollback on persistence or lifecycle-refresh failures.
Diagnostic quarantine evidence
internal/diagnostic/checks.go, internal/diagnostic/diagnostic_test.go
The diagnostic check reports quarantined mutations as non-blocking informational evidence. Blocking findings remain separate and continue to affect the diagnostic roll-up.
Doctor repair integration
cmd/engram/doctor.go, cmd/engram/doctor_test.go
doctor repair supports sync_mutation_required_fields, permits an omitted project, runs dry-run or apply quarantine mode, and writes the quarantine report. Tests cover both modes and preserve reparable pending mutations.

Explanation

The pull request implements a local dry-run/apply quarantine path, durable disposition metadata, transport exclusion, diagnostic visibility, and lifecycle unblocking for irreparable mutations [#626] [#340] [#690]. However, the change does not implement the linked requirement to backfill inferable session directories or repair frozen payloads for repairable mutations [#340]. The tests explicitly preserve reparable pending mutations.

Resolution

Add repair logic for inferable required fields, including session directory backfills and repairable session or observation mutation payloads. Keep quarantine limited to mutations that cannot be repaired, and report both repaired and unrepairable rows.

Full details: Out of Scope Changes check

Explanation

The schema migration, store lifecycle changes, diagnostic updates, CLI behavior, and tests directly support local mutation quarantine, transport unblocking, and doctor repair requirements in the linked issues.

4123-4125: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Refresh project state with the project-aware query.

On Line 4124, syncTargetKeyForProject(affectedProject) produces cloud:project-a, but quarantined project rows have target_key = 'cloud'. refreshSyncLifecycleTx therefore counts zero rows and can set the project lifecycle to healthy while another pending mutation for that same project remains transportable.

Call refreshProjectSyncStateTx(tx, affectedProject) here. Add a regression case with one quarantined mutation and one valid pending mutation in project-a; the project state must remain pending.

Proposed fix
 for affectedProject := range affectedProjects {
-	if err := s.refreshSyncLifecycleTx(tx, syncTargetKeyForProject(affectedProject)); err != nil {
+	if err := s.refreshProjectSyncStateTx(tx, affectedProject); err != nil {
 		return err
 	}
 }

Requesting changes. Quarantined rows remain in blocking pending diagnostics after repair, so Doctor can stay blocked forever. Lifecycle refresh also uses cloud:<project> while local journal rows use cloud, masking valid pending work. Filter quarantined rows from pending diagnostics and refresh the correct project lifecycle state, then add apply-then-Doctor regressions.

Quarantined rows stayed in the blocking pending diagnostics and in the cloud
upgrade legacy evaluator, so a store that had already been repaired could stay
blocked forever with no action left for an operator to take. They are now
reported as non-blocking evidence carrying their disposition metadata, while
genuinely pending work keeps blocking and leads the check roll-up.

The per-project lifecycle refresh also read the `cloud:<project>` bookkeeping
key, but enqueueSyncMutationTx writes every journal row under the default
`cloud` target key and keeps the project in its own column. Counting the
bookkeeping key always returned zero, so quarantining one row marked the whole
project healthy and masked its remaining pending work. The refresh now counts
the key the journal actually writes.

Claude-Session: https://claude.ai/code/session_01ThsP1FPiee266DqD58asTB
doctor repair accepts sync_mutation_required_fields without --project, but the
usage text still declared --project required for every repair command. Add a
check-specific usage line and a note so the two other repair checks keep
advertising --project as required.

Keep quarantined mutations visible to diagnostics.

ListPendingProjectMutations now filters out quarantined rows and does not scan their disposition fields. SyncMutationRequiredFieldsCheck.Run uses this method to emit informational quarantine evidence. After --apply, the diagnostic check therefore returns no evidence for the quarantined mutation.

Keep a pending-only query for cloud-upgrade evaluation. Use a diagnostic query that includes and scans quarantined rows.

Resolved. Quarantined rows no longer sit in the blocking pending diagnostics — they surface as non-blocking info findings carrying their disposition evidence, so a repaired store stops being blocked forever without the rows going invisible. The target-key mismatch is fixed at the root and verified rather than assumed: enqueueSyncMutationTx is the only non-test writer of sync_mutations and always writes target_key = "cloud", while cloud:<project> exists solely as a sync_state bookkeeping row, so the lifecycle refresh was counting a key no journal row ever carries and forcing healthy. The apply-then-Doctor regressions are in, plus the usage line for --project being optional on sync_mutation_required_fields.

Good catch extending it to listPendingProjectMutationsTx — quarantined rows were keeping engram cloud upgrade blocked through the same class of bug, on the exact surface the doctor's own next-step points at.

The merge with #819 composes the two rules rather than picking one: the cloud-in-use gate sits after the quarantine pass, so a local-only install still gets its quarantined evidence, and quarantine filtering cannot resurrect the local-only blocking regression since the count query already scopes to disposition = 'pending' in SQL. Verified against a built binary across all four combinations.

One follow-up, not a blocker and not a merge artifact: the quarantined_mutations and adjusted pending_mutations_evaluated check-level evidence is unreachable in practice, because resultFromFindings only uses the ok-evidence map when there are zero findings — and whenever a quarantined row exists there is at least one. The finding-level evidence carries the detail, so nothing is lost operationally, but if you want that count surfaced the envelope needs a small rethink.
