• 🟡 (09:47) Updated packages/core/src/session/execution/local.ts so the final cancellation event deletes the exact claim inside the same durable event transaction, resolving the crash window between marking a claim cancelled and deleting it.
• 🟡 (09:47) Tightened the acquisition latch in packages/core/src/session/execution/local.ts: if acquisition defects before producing a result, latch waiters receive false and terminate instead of waiting indefinitely.
• 🟡 (09:47) Updated packages/core/src/session/recovery.ts with the malformed-assistant projection quarantine fix.
• 🟡 (09:47) Designed the malformed-assistant starvation regression with 300 valid relational assistant rows whose serialized data is deliberately corrupted afterward, followed by a valid claim at sequence 301; four bounded recovery passes must quarantine all malformed rows and process the valid claim.
• 🟡 (09:48) Added the malformed-assistant starvation regression to packages/core/test/session-projector.test.ts.
• 🟡 (09:48) Initial tsgo --noEmit failed only on test construction in packages/core/test/session-projector.test.ts: line 2121 returned Effect.Effect<void, unknown, unknown> where the test body required Scope | Service | Service | TestConsole; line 2148 used malformed {} assistant data rejected by Drizzle’s typed insert boundary; line 2176 called unavailable Effect.repeatN in Effect 4.0.0-beta.83.
• 🟡 (09:48) Test-construction fix in packages/core/test/session-projector.test.ts: insert type-valid assistant rows first, corrupt their serialized data afterward via raw SQL, and replace unavailable Effect.repeatN with four explicit bounded passes sequenced using Effect.all.
• 🟡 (09:49) Core typecheck passed after the test-construction fixes.
• 🟡 (09:49) Four focused Bun test runs passed: 1. 3 passed, 11 filtered, 0 failed, 9 expect() calls across 1 file in 726.00 ms; 2. 2 passed, 57 filtered, 0 failed, 7 expect() calls across 1 file in 1.76 s; 3. 3 passed, 16 filtered, 0 failed, 10 expect() calls across 1 file in 233.00 ms; 4. 2 passed, 108 filtered, 0 failed, 13 expect() calls across 1 file in 1.69 s.
• 🟡 (09:49) Focused regressions passed for commit-to-registration interruption/acquisition handoff, quarantine of 300 malformed projections across four bounded passes, cancellation-setup wake preservation, and rollback of atomic cancellation publication.
• 🟡 (09:50) Complete recovery suite passed: 257 tests across 8 files, 0 failures, 785 expect() calls, runtime 22.94 s under Bun 1.3.14 (0d9b296a).
• 🟡 (09:50) Attempted old-source mutation controls against frozen v22 for test/session-execution-local.test.ts, test/session-projector.test.ts, and test/session-run-coordinator.test.ts, but the detached worktree at /tmp/opencode/session-recovery-v22-review lacked the effect package. Each attempted run reported 0 passed, 1 failed, and 1 unhandled error in roughly 29–31 ms.
• 🟡 (09:50) The blocked old-source mutation-control runs were explicitly excluded as evidence because they demonstrated only a missing-dependency environment problem, not expected failures in the frozen v22 behavior.
• 🟡 (09:51) Started background v23 source validation. Reported current gates: 257 recovery tests passed; acquisition-to-registration interruption, 300-row malformed-projection starvation, cancellation-setup wake preservation, and atomic final-cancellation claim deletion regressions passed; core typecheck passed. Old-source mutation controls remained unavailable due to missing detached-worktree dependencies.
