Adds the deterministic and semantic audit tooling used to drive the
release-readiness pass on the YAML question corpus:
- audit_yaml_corpus.py — read-only schema + authoring-convention audit
- format_yaml_questions.py — canonical formatter (idempotent)
- fix_yaml_hygiene.py — bulk hygiene fixups
- prepare_semantic_review_queue.py — emit JSONL queues per track for LLM review
- semantic_audit_questions.py — parallel LLM audit runner (gpt-5.4-mini)
- run_semantic_audit_tracks.py — per-track orchestrator wrapping the runner
- build_semantic_fix_queue.py — collect findings into a prioritized fix queue
- compare_semantic_passes.py — diff two semantic-audit passes for stability
- summarize_semantic_audit.py — markdown summary from findings JSONL
Also adds interviews/vault/audit/README.md describing the workflow.
Audit output artifacts (semantic-review-queue/, semantic-review-results/,
fresh-yaml-audit/) are produced by these scripts on demand and remain
untracked.
