Pass the caller-selected input field to the shared managed parse-failure
owner. Derive filename and field from one comparison selection, reporting
leftPath or rightPath while ordinary inspection continues to report path.
Preserve typed input classification and completed-left partial Evidence.
Replace weaker direct malformed-input cases with a compiled CLI workflow
covering both sides, the healthy comparison, and sibling inspection.
Document the input-attribution contract.
Validation: the public regression reproduced the generic path issue;
focused CLI, comparison and shared-reader controls passed after repair.
No managed assembly or external analysis provider was executed.
