# Session Continuity

## Last Session (2026-03-09)
- Completed `chat-provider-fixes` change set with three workstreams:
  - `chat-loop-hardening`: invalid required-arg tool calls now terminate cleanly, not replayed, assistant tool_call history trimmed consistently
  - `default-ai-settings`: Settings page saves default provider/model via `UserAISettings`; DB defaults authoritative over localStorage; backend fallback uses saved defaults
  - `suggestion-add-flow`: day suggestions use resolved provider/model (not hardcoded OpenAI); modal normalizes suggestion payloads for add-to-itinerary
- All three workstreams passed reviewer + tester validation
- Documentation updated for all three workstreams

## Active Work
- `chat-provider-fixes` plan complete — all workstreams implemented, reviewed, tested, documented
- See [plans/](../plans/) for other active feature plans
- Pre-release policy established — architecture-level changes allowed (see AGENTS.md)

## Known Follow-up Items (from tester findings)
- No automated test coverage for `UserAISettings` CRUD + precedence logic
- No automated test coverage for `send_message` streaming loop (tool error short-circuit, multi-tool partial success, `MAX_TOOL_ITERATIONS`)
- No automated test coverage for `DaySuggestionsView.post()` 
- `get_weather` error `"dates must be a non-empty list"` does not trigger tool-error short-circuit (mitigated by `MAX_TOOL_ITERATIONS`)
- LLM-generated name/location fields not truncated to `max_length=200` before `LocationSerializer` (low risk)
