Auditor self-test branch: real-world pipelines + cohesion Phase C + KB index (PR #8)

Bundles 12 commits validating the auditor + scrum_master architecture end-to-end:

- enrich_prd_pipeline / hard_task_escalation / scrum_master_pipeline stress tests
- Tree-split + scrum_reviews.jsonl + kb_query surfacing
- Verdict → audit_lessons feedback loop (closed)
- kb_index aggregator with confidence-based severity policy
- 9-run + 5-run empirical tests proved the predictive-compounding property
- Level 1 correction: temp=0 cloud inference for deterministic per-claim verdicts
- audit_one.ts dry-run CLI
- Fixes: static quoted-string guard, empirical-claim classification, symbol-resolver gate, repo-file size cap

See PR #8 for run-by-run commit history.
