Audit Logging & Compliance Framework

Every AI decision must be as auditable as a human decision.

An audit log you cannot trust is worse than no log at all — it gives you confidence without evidence. The schema below is the easy part. The staff-grade questions are the three that follow it: can anyone silently rewrite the record (tamper-evidence), what does seven years of retention actually cost (less than you think), and what watches the log itself (four automated checks, because nobody reads a 3 GB-a-month log by hand).

WHERE YOU ARE

You built tenant isolation in Multi-Tenant Isolation — every request carries a tenant_id and every query is scoped by it. Audit logging is the proof that isolation, and every other control, actually fired: when a regulator, an enterprise customer, or your own incident review asks “who saw whose data, and what did the model do,” this log is the answer. This section assumes the request path from earlier sections and turns the record of it into evidence.
