Both functions had:
try: ToolPresetManager().load_all() ...
except (OSError, ValueError, AttributeError) as e:
sys.stderr.write(f'[ERROR] Failed to set {preset_name}: {e}')
sys.stderr.flush()
sys.stderr.write is logging = NOT a drain = SS violation per MUST-NOT-DO #6.
New helpers:
- _set_tool_preset_result(preset_name: Optional[str]) -> Result[None]
Empty/None preset short-circuits to Result(data=None).
On failure: Result(data=None, errors=[ErrorInfo]).
- _set_bias_profile_result(profile_name: Optional[str]) -> Result[None]
Same pattern.
Legacy wrappers set the global state (or skip on empty preset) and
delegate to the _result helper. Cache invalidation runs regardless.
Audit: ai_client SS 9 -> 7. COMPLIANT 27 -> 29.
