Keep prompt reservations briefly after successful dispatch so rapid idle/message/error transitions cannot inject the same follow-up twice.
Route all production session prompt calls through the shared gate, restore skipped background resume state, release holds after abort/recovery paths, and preserve Ralph/ULW loop state when a dispatch is deferred.
Add regression coverage for session routing, static prompt route auditing, team-mode live messaging, model suggestion retries, call-omo-agent reuse, background parent wakes, runtime fallback, compaction recovery, Atlas, and Ralph/ULW loops.
Handle OpenCode session events that carry the session ID under properties.info.id or properties.info.sessionID so background tasks and continuation hooks do not miss idle/error/delete events.
Add regression coverage for nested session.idle events completing background tasks and waking continuation hooks.
Split 1021-line index.ts into 10 focused modules per project conventions.
New structure:
- error-classifier.ts: error analysis with dynamic status code extraction
- agent-resolver.ts: agent detection utilities
- fallback-state.ts: state management and cooldown logic
- fallback-models.ts: model resolution from config
- auto-retry.ts: retry helpers with mutual recursion support
- event-handler.ts: session lifecycle events
- message-update-handler.ts: message.updated event handling
- chat-message-handler.ts: chat message interception
- hook.ts: main factory with proper cleanup
- types.ts: updated with HookDeps interface
- index.ts: 2-line barrel re-export
Embedded fixes:
- Fix setInterval leak with .unref()
- Replace require() with ESM import
- Add log warning on invalid model format
- Update sessionLastAccess on normal traffic
- Make extractStatusCode dynamic from config
- Remove unused SessionErrorInfo type
All 61 tests pass without modification.
