## Handoff: team-plan → team-exec
- **Decided**: The next compatibility-first phase is contract freeze/alignment, not another runtime extraction: tighten tests around the actual tool-call support level, then align schema/docs wording to match.
- **Rejected**: No new `app/main.py` refactor in this slice, and no Anthropic streaming fallback implementation; that would turn the phase into a behavior change instead of a compatibility sync-up.
- **Risks**: Current docs can over-promise forced-tool fallback on Anthropic streaming; tests need to lock the current asymmetry explicitly so future refactors do not accidentally change it.
- **Files**: `tests/test_tool_call_bridge.py`, `app/anthropic_schema.py`, `DESIGN.md`, `README.md`
- **Remaining**: Add/adjust regression coverage, align wording in schema/docs, run focused + full unittest, then do the phase checkpoint commit/push while keeping local `main` synced with `origin/main`.
