• 🟡 (15:36) Located the interrupted-provider publication path in packages/core/src/session/runner/llm.ts:393: yield* withPublication(publisher.interruptAssistant("Provider Step outcome unknown after interruption")).
• 🟡 (15:36) Updated packages/core/src/session/runner/llm.ts, then ran 8 focused test files: 166 passed, 0 failed, 459 expect() calls in 15.65s.
• 🟡 (15:37) tsgo --noEmit initially failed at src/session/runner/llm.ts:397: Cause<LLMError> | Cause<StorageError> was not assignable to Cause<LLMError> because StorageError lacks retryable, retryAfterMs, module, method, and reason.
• 🟡 (15:37) Fixed the cause-type mismatch in packages/core/src/session/runner/llm.ts; subsequent tsgo --noEmit completed without errors.
• 🟡 (15:38) Removed temporary file /tmp/opencode/core-drizzle.config.ts; /tmp/opencode still contained core-drizzle, header.json, heap-retaining-20260915-092450, output-check, and session-recovery-full.patch.
• 🟡 (15:39) Re-ran the 8 focused test files after the type fix: 166 passed, 0 failed, 459 expect() calls in 13.96s; another tsgo --noEmit run passed.
• 🟡 (15:40) Verified packages/schema/package.json defines "typecheck": "tsgo --noEmit", depends on effect: "catalog:", and uses @tsconfig/bun, @types/bun, and @typescript/native-preview as catalog dev dependencies; the schema package typecheck passed.
• 🟡 (15:40) Assistant reported the completed design: 1. lease-fenced execution claims keyed by session, execution, and owner, with mutations requiring an unexpired lease and exactly one affected row; 2. ordinary acquisition never replaces claims and expired-claim reconciliation belongs exclusively to recovery; 3. durable exact recovery wake state promotes only the synthetic queued continue input; 4. cancellation atomically settles Step.Interrupted and deletes the exact claim, with successor wake delayed until cleanup; 5. compaction remains unsafe until Compaction.Ended commits; 6. recovery uses bounded deterministic batches and malformed-phase quarantine; 7. recovery message IDs derive from execution IDs and cross-session assistant relationships are transactionally rejected; 8. unpublished recovery migrations were squashed into one populated-predecessor-safe migration with NOT NULL, a phase CHECK, and corrected generated primary-key metadata; 9. the bounded wall-clock-skew lease assumption was documented.
• 🟡 (15:40) Assistant reported changed production/schema files: packages/core/schema.json, packages/core/src/database/migration.gen.ts, packages/core/src/database/schema.gen.ts, packages/core/src/database/migration/20260914170650_session-recovery.ts, packages/core/src/session/compaction.ts, packages/core/src/session/context-epoch.ts, packages/core/src/session/execution/claim.ts, packages/core/src/session/execution/local.ts, packages/core/src/session/input.ts, packages/core/src/session/message-updater.ts, packages/core/src/session/projector.ts, packages/core/src/session/recovery-id.ts, packages/core/src/session/recovery.ts, packages/core/src/session/run-coordinator.ts, packages/core/src/session/runner/index.ts, packages/core/src/session/runner/llm.ts, packages/core/src/session/runner/publish-llm-event.ts, packages/core/src/session/sql.ts, and packages/schema/src/session-event.ts.
• 🟡 (15:40) Assistant reported deleted unpublished migration files: packages/core/src/database/migration/20260914214636_session-execution.ts, packages/core/src/database/migration/20260914222526_session-execution-phase.ts, and packages/core/src/database/migration/20260914235657_session-execution-lease.ts.
• 🟡 (15:40) Assistant reported changed test files: packages/core/test/database-migration.test.ts, packages/core/test/session-execution-local.test.ts, packages/core/test/session-projector.test.ts, packages/core/test/session-runner-recorded.test.ts, packages/core/test/session-runner-tool-events.test.ts, and packages/core/test/session-runner.test.ts.
• 🟡 (15:40) Assistant reported final validation: focused affected tests with --printConsoleTrace passed 166/166 with 0 failures; the full Core suite passed 1124/1124 with 0 failures; the Core migration check passed with no ungenerated schema changes; bun typecheck passed in both packages/core and packages/schema; and git diff --check passed.
• 🟡 (15:40) Assistant reported remaining risk: external provider and tool calls retain an unavoidable instruction-level race after the immediate synchronous ownership check; no speculative infrastructure was added.
• 🟡 (15:40) Assistant reported lease correctness assumes clock skew plus scheduling delay remains below the lease window, and this requirement is documented in source.
• 🟡 (15:40) Assistant reported no implementation blocker; the required repo-setup skill was unavailable, so repository and package instructions were read directly before editing.
• 🟡 (15:40) Assistant reported no commit or service operation occurred, and existing changes to AGENTS.md, .lore.md, perf.data, and perf.data.old remained untouched.
