vcsdd-converge

Runs Phase 6 convergence check for active VCSDD feature, validating finding diminishment to zero, real file paths, criteria coverage, no duplicates, open findings, hardening artifacts, and traceability. Use after Phase 5.

What

Runs the convergence check (Phase 6). Validates all four convergence dimensions and either marks the feature complete or routes back to Phase 3 for another adversary pass.

When

Run after Phase 5 (formal hardening) completes. Requires active feature at phase 6.

How

Check finding diminishment: compare convergenceSignals.findingCount across iterations
- Completion requires the current sprint to reach findingCount = 0
- For iterations beyond the first, completion also requires findingCount < previousFindingCount

Check finding specificity: verify all evidence.filePath values are real files

for f in reviews/sprint-*/output/findings/*.json; do
  path=$(jq -r '.evidence.filePath' "$f")
  ls "$path" 2>/dev/null || echo "HALLUCINATED: $path"
done

Check criteria coverage: verify reviews/sprint-N/output/verdict.json sets convergenceSignals.allCriteriaEvaluated = true and that convergenceSignals.evaluatedCriteria matches the approved contract's CRIT-XXX set exactly
- every contract criterion must be listed
- no extra criterion IDs may appear
Check duplicate detection: convergenceSignals.duplicateFindings must be empty
Check open finding beads: no adversary-finding bead may remain in open status
Check formal hardening artifacts:
- verification/verification-report.md exists and was written after entering Phase 5
- verification/security-report.md exists and was written after entering Phase 5
- verification/purity-audit.md exists and was written after entering Phase 5
- verification/security-results/ contains at least one captured output artifact written after entering Phase 5
- all required proof obligations are proved (required obligations may not finish as skipped)
Check finding traceability coverage:
- every persisted reviews/sprint-*/output/findings/FIND-NNN.json must have a matching adversary-finding bead
All 4 dimensions converged?
- YES: record gate PASS, transition to complete, display success summary
- NO: record failure details, check iteration limit (max 2)
  - Under limit: route back to Phase 3 for re-review
  - Over limit: write escalation, pause for human
