/home/byk/Code/opencode, explicitly forbidding lore/recall and prior-context retrieval; this was designated the single evidence-or-blocker retry.continue after Step.Ended/Compaction.Ended; replay-safe outbox settlement; exact claim cancellation when the user declines after step finish; conflicting retry not arming wake; poisoned-row quarantine and bounded progress; newest-assistant supersession; exact recovery-input priority; ordinary wake intent including resume:false; lease expiry/takeover; supported pre-feature-to-final migration and fresh schema; replay; and whether regressions reach real failure windows.file:line evidence and a concrete failure sequence; if no defect exists, output PASS plus evidence-backed residual risks/testing gaps; if inspection is blocked, quote the exact tool/error and affected scope./home/byk/Code/opencode/packages/core/src/session/recovery.ts:286-298 showed the recovery layer runs recover(), logs caught causes as "Failed to recover Sessions", repeats on Schedule.spaced("10 seconds"), forks scoped, and depends on Database.node, EventV2.node, SessionProjector.node, and SessionExecution.node./home/byk/Code/opencode/packages/core/src/session/input.ts:43-99 showed SessionInput.admit: an existing equivalent input can call requestWake(db, input) when requestExecution is true; a new SessionEvent.PromptAdmitted uses the same wake request as its commit callback; defect recovery re-reads the row, rejects non-equivalent input with LifecycleConflict, and re-requests wake when appropriate./home/byk/Code/opencode/packages/core/src/session/input.ts:101-122 showed requestWake sets SessionInputTable.wake_pending: true only where id, session_id, and promoted_seq IS NULL match; if no row updates, an already-promoted matching row is accepted, otherwise it dies with SessionInput.LifecycleConflict./home/byk/Code/opencode/packages/core/src/session/input.ts:159-229 showed projectPrompted atomically sets promoted_seq and wake_pending: false for an unpromoted matching input, validates replay through matchesProjection and exact promotedSeq, supports insertion of a missing already-promoted row, and then calls settleRecoveryWake; settleRecoveryWake clears SessionRecoveryTable.wake_pending only for the exact session_id + continuation_message_id whose wake is currently true./home/byk/Code/opencode/packages/core/src/session/input.ts:277-380 showed promotion behavior: publish emits SessionEvent.Prompted and tolerates LifecycleConflict only if the stored row is already promoted; promoteSteers orders eligible steer inputs by ascending admitted_seq; promoteNextQueued selects the oldest unpromoted queue input by ascending admitted_seq; promoteExact requires the exact messageID, session, unpromoted state, and delivery: "queue", otherwise dies with Pending recovery input not found: ${messageID}./home/byk/Code/opencode/packages/core/src/session/projector.ts:357-382 showed durable SessionEvent.Prompted projects through SessionInput.projectPrompted and then run(db, event), while durable SessionEvent.PromptAdmitted projects through SessionInput.projectAdmitted./home/byk/Code/opencode/packages/core/src/session/projector.ts:392-448 showed SessionEvent.Step.Recovered derives a continuation ID via continuation(event.data.executionID), returns on an existing recovery row for the same execution/session, verifies any supplied assistantMessageID is the latest assistant by descending SessionMessageTable.seq, runs the recovered event, admits a queue prompt with exact text "continue", and inserts SessionRecoveryTable with phase, wake_pending: true, and the continuation message ID using .onConflictDoNothing()./home/byk/Code/opencode/packages/core/src/session/projector.ts:388-461 showed Step.Started, Step.Ended, Step.Failed, Step.Interrupted, and Compaction.Ended project via run(db, event); SessionEvent.Retried remains commented out at line 460./home/byk/Code/opencode/packages/core/src/session/execution/local.ts:23-99 showed local execution creates a random ownerID and executionID, inserts a "ready" lease row with expires_at = now + leaseDuration, declines work when insertion conflicts, selects the oldest non-poisoned recovery row where wake_pending: true and recovery_error IS NULL, passes its continuationMessageID to input.run, and races the run against periodic SessionExecutionClaim.update renewal every leaseDuration / 3./home/byk/Code/opencode/packages/core/src/session/execution/local.ts:73-95 showed exit cleanup removes the active in-memory claim; successful execution clears the durable claim; interruption leaves it for expiry/takeover; non-interrupt failure clears it unless the current phase is "unknown" or "continue"./home/byk/Code/opencode/packages/core/src/session/execution/claim.ts:25-66 confirmed claim fencing requires matching session_id, id, and owner_id plus expires_at > now; update renews to now + SESSION_EXECUTION_LEASE_MS, clear deletes only a still-valid claim, and either operation dies with SessionExecutionClaim.Lost when no row matches. The code comment states execution IDs fence a node after takeover and lease duration must exceed maximum deployment clock skew plus one renewal interval./home/byk/Code/opencode/packages/core/src/session/runner/publish-llm-event.ts:421-468 showed "tool-error" validates that the tool was called, its name is unchanged, and it is unsettled before publishing SessionEvent.Tool.Failed; "step-finish" calls flush(), sets assistantActive = false, rejects duplicate settlement, and records { finish: event.reason, tokens: tokens(event.usage) }; "provider-error" marks provider failure and calls failAssistant(event.message). interruptAssistant is defined at line 240 and exported at line 460.
