- Status: COMPLETE
- Workflow state: DONE
Understanding
The remaining changelog count is not itself a defect. It mixes old release
claims, unverifiable claims, extractor artifacts and potentially repeated false
positives. This iteration must review a stable sample before selecting any
behavior change.
Execution plan
- Build a clean runtime from tracked
18cc21b.
- Apply only the ticket-002 changelog diagnostic patch.
- Re-run the unchanged seven-repository corpus.
- Select a deterministic stratified sample from residual findings.
- Label the sample with explicit, reviewable rules.
- Rank false-positive classes by repository spread and count.
- Add one red regression and nearby hard negatives for the leading safe class.
- Implement and evaluate one correction, or reject the hypothesis.
- Run full validation and update readiness evidence.
Guardrails
- A release claim is not implementation evidence merely because its words
resemble a module.
- Historical age alone does not make a diagnostic false.
- Missing AST support is reported as incomplete evidence, not silently ignored.
- Current unrelated and generated workspace changes are excluded from the A/B
runtime.
Actual changes
- Initialized and approved the ticket from the continuation message.
- Re-ran the unchanged corpus successfully from tracked
18cc21b plus only the
ticket-002 diagnostic patch.
- Built and reviewed a deterministic 168-record stratified sample.
- Selected exact file-only update bookkeeping: 28 sampled and 547 total
findings across five repositories.
- Added a red/green regression with behavioral hard negatives.
- Re-ran the corpus with only this correction: removed 547 review findings and
188 secondary unlinked warnings while every graph fingerprint stayed stable.
- Passed full verification, five SDK examples, the production dependency
audit, CLI/MCP/A2A smoke checks and Docker smoke. The suite reported 242
tests: 241 passed, none failed and the local Java fixture was skipped because
this environment has no JDK; required CI supplies JDK 17.
- Updated readiness evidence and closed the ticket with 1,306 deliberately
retained residual findings.
- After user review, moved the executable audit reproducer out of the ticket
directory into
scripts/research/; the ticket now contains evidence only.
