This track executes after startup_speedup, test_batching_refactor, and
qwen_llama_grok_integration land. Section 10 documents the expected
post-tracks codebase state and answers 6 critical coordination questions:
- Q1: Existing _send_<vendor>() functions (returning str) are renamed
to _send_<vendor>_result() and changed to return Result[str] (Option A:
clean rename, contained to internal callers).
- Q2: send_openai_compatible in src/openai_compatible.py STAYS as-is
(it raises at the SDK boundary; correct per Fleury). The new
_send_<vendor>_result() functions catch and convert to ErrorInfo.
- Q3: Deprecation warning on send() will produce Python warnings in
tests; filterwarnings in conftest.py silences them during transition.
- Q4: The except ProviderError clauses in src/ai_client.py become
dead code after the refactor and are removed in Phase 3.
- Q5: ProviderError is FULLY REPLACED by ErrorInfo (a value, not an
exception). ProviderError removed entirely; ErrorInfo is the new
error type.
- Q6: ProviderError.ui_message() moves to ErrorInfo.ui_message().
Phase 1 also adds a baseline verification task to confirm the 3 pending
tracks have merged before proceeding.
Also renumbered Out of Scope (11) and See Also (12) sections to
preserve monotonic section numbers.
