Both classify functions had:
try:
sdk = _require_warmed('xxx')
if isinstance(exc, sdk.SomeException): return ErrorInfo(...)
...
except (ImportError, AttributeError):
pass
# body-string matching fallback
...
Body: bare 'except: pass' = SS violation (silent recovery).
Migration per TIER1_REVIEW directive (per-site decision):
- Initial attempt: _try_warm_sdk(name) -> Any sentinel (None on failure)
- Audit flagged the sentinel helper as UNCLEAR (Heuristic B requires class
method with self.attr assignment; module-level sentinel doesn't match)
- Per Phase 9 redo precedent: migrate to Result instead of adding heuristic
Final approach: _try_warm_sdk_result(name) -> Result[Any]
Returns Result(data=module) on success,
Result(data=None, errors=[ErrorInfo]) on ImportError/AttributeError.
Classify callers check result.ok and use result.data on success.
Audit: ai_client SS 2 -> 0; UNCLEAR 1 -> 0 (after Result migration).
COMPLIANT 32 -> 33.
