Full details: Description checkExplanation The description explains the implementation, affected diagnostics, linked issue, and test results. It uses a Testing section instead of Test plan and omits the checklist, but it remains sufficiently complete. Full details: Linked Issues checkExplanation The changes satisfy issue Full details: Docstring CoverageExplanation Docstring coverage is 51.28% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 39 functions across 14 files. (1 skipped: 1 unsupported.)

Add the validation details to the defect entry.
This fragment explains the root cause and ownership fix, but it does not record the forced copied-minor-GC coverage or the ENOENT util.inspect coverage described by this PR. Add one short validation sentence.
Based on learnings: defect-fix changelog entries must include root-cause and validation details.
Suggested addition
Error's existing move and finalize hooks keep the record in sync.
+ Forced copied-minor-GC tests cover diagnostic retention and ENOENT
+ `util.inspect` round-tripping.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
