Closes#1901
Add 'default_strategy' config option (default: 'continue') to control whether ralph-loop creates a new session per iteration ('reset') or keeps the same session ('continue'). The 'reset' strategy keeps the model in the smart zone by starting with fresh context for each iteration.
Supports --strategy flag for per-command override.
Replace exact call count assertions with delta-based checks:
- capture errorSpy.mock.calls.length before processing events
- slice to only check calls made during this test's execution
- use try/finally to guarantee mockRestore() even on assertion failure
This prevents test pollution from cross-file spy leakage in CI batch runs.

Fixes#1804, fixes#1962
The migration entry 'gpt-5.2-codex → gpt-5.3-codex' caused the plugin to silently overwrite user configs on every startup with a model that doesn't exist in the OpenAI API. Users explicitly setting gpt-5.2-codex (the correct current model) were forced to revert their config manually every session.
- BUG-7: Add gpt-5-nano as final fallback in multimodal-looker model requirements
- BUG-14: Remove hardcoded LIBRARIAN_MODEL, let librarian resolve through normal fallback chain
- Update snapshots and tests to reflect new fallback behavior
When browserProvider is not set, agent-browser skill should NOT resolve.
Test assertions were inverted — expected 'Skills not found' but asserted the opposite.
Unhandled SQLite exceptions (SQLITE_BUSY, database locked, etc.) in queueMicrotask/setTimeout callbacks could crash the entire process. Added try/catch/finally to ensure db.close() is always called and errors are logged instead of crashing.
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.

Update schema comment to match actual code default [400, 429, 503, 529].
Previously the comment omitted 400 which is included in the code default.

Revert test name and assertion to original behavior per PR review feedback.
The test now correctly expects Atlas to respect uiSelectedModel instead of using its own fallback chain.

Make provider auto-retry signal detection respect timeout_seconds setting:
- When timeout_seconds=0, disable quota-based fallback escalation
- Only treat auto-retry signals as errors when timeout is enabled
- Add test to verify behavior when timeout_seconds is disabled
- Update documentation to explain timeout_seconds=0 behavior
This allows users to disable timeout-based fallbacks while keeping
error-based fallback functionality intact.
Refactor retry signal detection to be provider-agnostic:
- Replace hardcoded Copilot/OpenAI checks with generic pattern matching
- Detect any provider message containing limit/quota keywords + [retrying in X]
- Add OpenAI pattern: 'usage limit has been reached [retrying in X]'
- Update logging to use generic 'provider' instead of specific names
- Add 'usage limit has been reached' to RETRYABLE_ERROR_PATTERNS
This enables fallback escalation for any provider that signals automatic
retries due to quota/rate limits, not just Copilot and OpenAI.
Closes PR discussion: generalize retry pattern detection
- Extract duplicated auto-retry logic (~40 lines each) from session.error and
message.updated handlers into shared autoRetryWithFallback() helper
- Fix userFallbackModels path in model-resolution-pipeline to respect
constraints.connectedProviders parameter instead of reading cache directly,
matching the behavior of categoryDefaultModel and fallbackChain paths
Bug fixes:
1. extractStatusCode: handle nested data.statusCode (Anthropic error structure)
2. Error regex: relax credit.*balance.*too.*low pattern for multi-char gaps
3. Zod schema: bump max_fallback_attempts from 10 to 20 (config rejected silently)
4. getFallbackModelsForSession: fallback to sisyphus/any agent when session.error lacks agent
5. Model detection: derive model from agent config when session.error lacks model info
6. Auto-retry: resend last user message with fallback model via promptAsync
7. Persistent fallback: override model on every chat.message (not just pendingFallbackModel)
8. Manual model change: detect UI model changes and reset fallback state
9. Agent preservation: include agent in promptAsync body to prevent defaulting to sisyphus
Additional:
- Add sessionRetryInFlight guard to prevent double-retries
- Add resolveAgentForSession with 3-tier resolution (event → session memory → session ID)
- Add normalizeAgentName for display names like "Prometheus (Planner)" → "prometheus"
- Add resolveAgentForSessionFromContext to fetch agent from session messages
- Move AGENT_NAMES and agentPattern to module scope for reuse
- Register runtime-fallback hooks in event.ts and chat-message.ts
- Remove diagnostic debug logging from isRetryableError
- Add 400 to default retry_on_errors and credit/balance patterns to RETRYABLE_ERROR_PATTERNS
The \b word boundary regex treats '-' as a boundary, causing
'sisyphus-junior-session-123' to incorrectly match 'sisyphus'
instead of 'sisyphus-junior'.
Sorting agent names by length (descending) ensures longer names
are matched first, fixing the hyphenated agent detection issue.
Fixes cubic-dev-ai review issue #8
- Add normalizeFallbackModels helper to centralize string/array normalization (P3)
- Export RuntimeFallbackConfig and FallbackModels types from config/index.ts
- Fix agent detection regex to use word boundaries for sessionID matching
- Improve tests to verify actual fallback switching logic (not just log paths)
- Add SessionCategoryRegistry cleanup in executeSyncTask on completion/error (P2)
- All 24 runtime-fallback tests pass, 115 delegate-task tests pass
Add shared utility to normalize fallback_models config values.
Handles both single string and array inputs consistently.

Replace word-boundary regex with stricter patterns that match
status codes only at start/end of string or surrounded by whitespace.
Prevents false matches like '1429' or '4290'.
