• 🟡 (08:31) Recreated strict disposable smoke harness at /tmp/opencode/session-recovery-v20-smoke.mjs; /tmp/opencode existed with permissions drwxr-xr-x.
• 🟡 (08:31) Exact rebuilt artifact smoke passed four isolated launches using authenticated health checks; every launch reported healthy: true, version 1.18.30, and empty stderr. Ports were 19077 initially, then 18545, 11971, and 29383.
• 🟡 (08:31) Artifact migration/schema smoke verified defaults: session.wake_attempts=0, session_input.wake_pending=false, session_recovery.wake_pending=true, and session_recovery.wake_attempts=0.
• 🟡 (08:31) Artifact smoke verified index session_execution_recovery_scan_idx with SQL CREATE INDEX \session_execution_recovery_scan_idx` ON `session_execution` (`recovery_error`,`expires_at`,`time_created`,`id`)`.
• 🟡 (08:31) Synthetic continuation smoke began with execution_count=1, recovery_count=0, input_count=0, message_count=0, and event_count=0. After the second restart it had execution_count=0, recovery_count=1, input_count=1, message_count=2, and event_count=2.
• 🟡 (08:31) Synthetic execution recovery-final-v20 recovered to phase ready with wake_pending=0, wake_attempts=2, and recovery_error=null. Continuation input msg_recovery_continue_recovery-final-v20 had prompt {"text":"continue"}, delivery queue, promoted_seq=1, and wake_pending=0; emitted events were sequence 0 session.next.step.recovered.1 and sequence 1 session.next.prompted.1.
• 🟡 (08:31) Duplicate-free third restart preserved exact post-recovery totals: execution_count=0, recovery_count=1, input_count=1, message_count=2, and event_count=2; no disposable artifact server remained afterward.
• 🟡 (08:31) Rebuilt packages/opencode/dist/server/opencode-server SHA-256 was d0c78e881892d4f894fab7f6be00643c133ca21f9d2c88ae0d5ff31215393021.
• 🟡 (08:32) Froze v20 as /tmp/opencode/session-recovery-final-v20.patch; SHA-256 24352107c74d8245fcba7f8571ba0be4b7fc514e6c73cfbf0498f0c25f29f9ba. Patch contained 34 paths with 8,425 insertions and 479 deletions.
• 🟡 (08:32) Frozen v20’s 34 paths were: packages/client/src/generated/types.ts, packages/core/schema.json, packages/core/src/database/migration.gen.ts, packages/core/src/database/migration/20260914170650_session-recovery.ts, packages/core/src/database/schema.gen.ts, packages/core/src/session.ts, packages/core/src/session/compaction.ts, packages/core/src/session/context-epoch.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.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, 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-prompt.test.ts, packages/core/test/session-run-coordinator.test.ts, packages/core/test/session-runner-recorded.test.ts, packages/core/test/session-runner-tool-events.test.ts, packages/core/test/session-runner.test.ts, packages/core/src/server/routes/instance/httpapi/server.ts, packages/schema/src/session-event.ts, packages/schema/test/event-manifest.test.ts, packages/sdk/js/src/v2/gen/types.gen.ts, packages/sdk/openapi.json, packages/server/src/routes.ts, new packages/core/src/session/execution/claim.ts, and new packages/core/src/session/recovery-id.ts.
• 🟡 (08:32) Working tree also showed local changes outside frozen v20: modified .lore.md and AGENTS.md, plus untracked perf.data and perf.data.old; status additionally showed deleted packages/core/src/database/migration/20260914214636_session-execution.ts and packages/core/src/database/migration/20260914222526_session-execution-phase.ts.
• 🟡 (08:32) Verified frozen v20 against a detached worktree at base commit ab9408c81c (feat(app): adapt vertical tab density): patch applied cleanly and passed whitespace checks.
• 🟡 (08:32) Previous security review applied to rejected v19 and was explicitly removed as an approval gate. Fresh correctness and security reviews were requested for immutable v20, focused on post-finalizer cancellation order, expired cancelled crash cleanup, the direct-runner unknown-state contract, and snapshot fencing.
• 🟡 (08:33) Started independent correctness review task ses_f5180d5e6ffeUS5WQw5h1K2sPR and security review task ses_f51808c1affeB5LJt71L2pUREb; both were running asynchronously.
• 🟡 (08:33) Completed high-priority implementation tasks: moved cancellation settlement after runner finalizers join; cleared expired durably cancelled claims during recovery; fenced snapshot writes at ownership boundaries; added cancellation-crash and finalizer-order regressions; ran full package validation and isolated artifact restart smoke.
• 🟡 (08:33) Remaining high-priority task was in progress: obtain independent correctness and security approval for the frozen revised candidate.
• 🟡 (08:33) Validation summary for frozen v20: Core had 1,188 passing tests; recovery gate had 251 passing tests; six package typechecks passed; migration consistency passed; exact isolated artifact smoke passed; live services remained untouched.
