Compliance posture

• AuditEntry type (in @repo/core-shared/audit) has no payload/body/oldValue/newValue fields — type system enforces DPA "what NOT to log".
• Append-only Payload collection (update: () => false); erasure uses overrideAccess: true for the privileged path.
• AUDIT_PSEUDONYM_SALT env REQUIRED in production. Validated at bind time.
