- run_claude_models_parallel: catch all exceptions in the per-model
worker and wrap unexpected ones into a ClaudeCLIError so the
documented 'errors as values' contract holds for OSError, ValueError,
etc., not just ClaudeCLIError. Without this, an unexpected raise in
any layer (rate limiter file I/O, infer_provider, etc.) abandons the
remaining models' results and crashes the calling test.
- test_run_claude_places_extra_args_before_prompt: drop the dead first
branch of the 'or' assertion — cmd[-3:] never matches that shape, so
the alternative was misleading dead code.
- basic_messaging_{non_streaming,streaming}/test_*.py: extract the
shared cell body into tests/claude_code/_basic_messaging.py.
Each per-provider file now declares its model list and calls
run_basic_messaging_cell(), eliminating ~700 lines of copy-paste
across 10 files. Updated _builder_unit_tests/test_v0_layout.py to
accept the helper-based pattern alongside direct run_claude() calls.
