## How to navigate

- New visitor → start at `kb/INDEX.md`
- Auditor → start at `kb/AUDIT_TRAIL.md`
- Engineer onboarding → start at `70-docs/02-architecture.md`
- BFSI compliance review → `kb/security/` + `70-docs/04-failure-modes.md` + `logs/hallucinations.jsonl`
- Buyer-side curiosity → any `kb/policies/<id>.md` ends with a "What the bot will and won't say" section.
