• 🟡 (15:47) Search of /tmp/opencode/session-recovery-v7-check/packages/sdk/openapi.json found 3 schemas: SessionNextPromptAdmitted at line 28545, SessionNextStepInterrupted at line 29120, and SessionNextStepRecovered at line 29178.
• 🟡 (15:49) /tmp/opencode/session-recovery-v7-check/packages/sdk/openapi.json lines 29120-29176 define SessionNextStepInterrupted: event id matches ^evt_; type is enum ["session.next.step.interrupted"]; optional durable requires aggregateID, seq, and version; location references #/components/schemas/LocationRef; data requires numeric timestamp, sessionID matching ^ses, assistantMessageID matching ^msg_, and error referencing #/components/schemas/SessionErrorUnknown; both event and data reject additional properties.
• 🟡 (15:49) /tmp/opencode/session-recovery-v7-check/packages/sdk/openapi.json lines 29178-29238 define SessionNextStepRecovered: event id matches ^evt_; type is enum ["session.next.step.recovered"]; optional durable requires aggregateID, seq, and version; location references #/components/schemas/LocationRef; data properties are numeric timestamp, sessionID matching ^ses, string executionID, optional assistantMessageID matching ^msg_, and phase enum ["ready", "unknown", "continue"]; required data fields are ["timestamp", "sessionID", "executionID", "phase"]; both event and data reject additional properties.
• 🟡 (15:49) Assistant reported that the frozen inputs and all 33 applied blobs matched after tracing the five v7 blockers through persistence, projection, runner state, ownership fencing, startup wiring, generated contracts, migrations, and focused regressions; final unchanged-state verification was underway without executing the SEA or tests.
• 🟡 (15:51) Final verification artifacts: /tmp/opencode/session-recovery-final-v8.patch SHA-256 is 446412b56ac31b2a60f98765b5f14955a771f6074ebeb9309f603a0ceefad1bc; /home/byk/Code/opencode/packages/opencode/dist/server/opencode-server SHA-256 is f4f0bd585d33bd47114b2d8d54082c2b061380771c808e909223350e62c8c72f; base commit is ab9408c81cc9916177641ae8e9f08624fc27b5b9; verification found 33 patch entries and 33 applied paths, a clean index, and exact old/new blob matches.
• 🟡 (15:53) /tmp/opencode/session-recovery-final-v8.patch changes createLLMEventPublisher in publish-llm-event.ts: failAssistant publishes SessionEvent.Step.Failed through publishEvent using { commit: input.eventCommit }.commit, then sets assistantActive = false and assistantFailed = true; direct events.publish usage is removed for this path.
• 🟡 (15:53) /tmp/opencode/session-recovery-final-v8.patch adds interruptAssistant(message: string, commit: () => Effect.Effect<void> = input.eventCommit): it returns if assistantFailed, flushes, starts or obtains the assistant, publishes SessionEvent.Step.Interrupted with sessionID, timestamp, assistantMessageID, and { type: "unknown", message }, uses the supplied commit, then sets assistantActive = false and assistantFailed = true; interruptAssistant is added to the publisher’s returned interface.
• 🟡 (15:53) /tmp/opencode/session-recovery-final-v8.patch routes SessionEvent.Tool.Failed, SessionEvent.Text.Started, SessionEvent.Text.Delta, SessionEvent.Reasoning.Started, SessionEvent.Reasoning.Delta, SessionEvent.Tool.Input.Delta, SessionEvent.Tool.Called, and SessionEvent.Tool.Success through publishEvent instead of direct events.publish.
• 🟡 (15:53) /tmp/opencode/session-recovery-final-v8.patch changes publication-state ordering: tool.settled is set only after SessionEvent.Tool.Failed or SessionEvent.Tool.Success publication succeeds; tool.called, tool.providerExecuted, and tool.providerMetadata are updated only after SessionEvent.Tool.Called succeeds; providerFailed is set only after failAssistant(event.message) succeeds. For tool calls, local providerExecuted = event.providerExecuted === true is published before being committed to tool state.
• 🟡 (15:53) /tmp/opencode/session-recovery-final-v8.patch changes packages/core/src/session/sql.ts to import sql from drizzle-orm and check from drizzle-orm/sqlite-core, and adds export const MAX_WAKE_ATTEMPTS = Number.MAX_SAFE_INTEGER.
• 🟡 (15:53) Assistant’s final review found MUST-FIX: None and CONCERN: None, concluding the acknowledged interval before external provider/tool dispatch is irreducible, the implementation does not claim exactly-once dispatch, and uncertain work is never replayed.
• 🟡 (15:53) Assistant PASS item 1, frozen inputs: verified base ab9408c81cc9916177641ae8e9f08624fc27b5b9, patch SHA-256 446412...ad1bc, and SEA SHA-256 f4f0bd...c72f; all 33 paths and old/new blob hashes matched, reverse application succeeded, and the index remained clean.
• 🟡 (15:53) Assistant PASS item 2, clean EOF: an active assistant lacking Step settlement receives durable Step.Interrupted; failed publication leaves the claim unknown for recovery; empty streams create no assistant. References: runner/llm.ts:437-444, publish-llm-event.ts:241-260, and session-runner.test.ts:958-999.
• 🟡 (15:53) Assistant PASS item 3, settlement ordering: assistant, provider, tool-called, and tool-settled flags change only after publication succeeds. References: publish-llm-event.ts:221-239,262-280,362-457; publication-defect regressions cover Step.Failed and local Tool.Success in session-runner.test.ts:2049-2121.
• 🟡 (15:53) Assistant PASS item 4, poison claims: conversion failure quarantines the acquired execution identity, and per-row failure isolation allows later batches to advance. References: recovery.ts:69-117,143-212; explicit 100-poison/claim-101 regression in session-projector.test.ts:1545-1608.
• 🟡 (15:53) Assistant PASS item 5, wake fairness: reservations change MAX_WAKE_ATTEMPTS to 1, preserve attempts/wake/error CAS predicates, guarantee retry capacity, and rotate work. References: recovery.ts:215-333,335-432; regression session-projector.test.ts:1611-1683.
• 🟡 (15:53) Assistant PASS item 6, constraint parity: incremental and full schemas use session_wake_attempts_check and session_recovery_wake_attempts_check with identical bounds. References: 20260914170650_session-recovery.ts:9-11,39, schema.gen.ts:212,248, and schema.json:2541-2549.
• 🟡 (15:53) Assistant PASS item 7, lease fencing: exact session/execution/owner plus unexpired-lease guards cover renewal, mutation, clear, publication, context updates, provider dispatch, and local-tool startup. References: execution/claim.ts:25-66, execution/local.ts:29-99, runner/llm.ts:297-349, and context-epoch.ts:127-194.
• 🟡 (15:53) Assistant PASS item 8, cancellation: renewal continues through interruption finalizers; cleanup precedes pending successors and never deletes replacement ownership. References: execution/local.ts:103-132 and run-coordinator.ts:99-125.
• 🟡 (15:53) Assistant PASS item 9, recovery identity: only expired, non-superseded claims convert; exact synthetic continuations remain isolated from ordinary queues and are revalidated at promotion. References: recovery.ts:119-165, input.ts:321-397,561-598, and projector.ts:399-456.
• 🟡 (15:53) Assistant PASS item 10, reconciliation: stream failure after Step finish never commits Step.Ended; hosted and local tools settle or become unknown before continuation. References: runner/llm.ts:395-476; regressions session-runner.test.ts:1975-2257.
• 🟡 (15:53) Assistant PASS item 11, migration and API lineage: one tracked recovery migration appears at migration.gen.ts:43; populated-predecessor coverage is in database-migration.test.ts:166-228; server startup wires recovery at packages/server/src/routes.ts:27-39 and packages/opencode/.../server.ts:299-304; Schema, generated SDK types, and OpenAPI agree on the new events.
• 🟡 (15:53) Assistant did not build, execute /home/byk/Code/opencode/packages/opencode/dist/server/opencode-server, or run tests, in accordance with the instruction, and issued the final disposition MERGE.
