yezhwi Diagnosability Review
Run only in REVIEWING: harness review diagnosability --file <file> rejects other task states.
Read .harness/observability.yaml, changed files, declared direct dependencies, and existing logging, correlation, masking, exception-handler, and reason-code conventions.
Do not scan whole repository. Do not add code. Do not prescribe logger framework.
For each review, create input for harness review diagnosability --file <file> with all checks:
business_keys
external_failure_context
state_transitions
caller_rejections
sensitive_data
duplicate_exception_logging
low_value_logging
Use pass, fail, or not_applicable. Every fail needs concrete FND-* DIAG Finding with linked REQ-*, code location, scenario, severity, reason code, and static-compliance required checks.
Never recommend full-object logging, method entry/exit logs, automatic insertion, or generic logging best practice. Claim only reviewed-scope evidence.
