Program.cs built the BIG-nummer reveal's audit resource ref as
"brief/" + ctx.Zorgverlener().Bsn. AuditAuthz persists that to the
AuthzAudit.Resource column in SQLite and /admin/audit renders it, so a BSN
reached durable storage and a UI on the one trail four documents describe as
data-minimised and PII-free — on the endpoint whose own comment promises the
audit carries no PII.
The ref is now "brief". Nothing is lost: BriefStore keys one brief per owner,
so the id named what the row's acting principal already implies.
The existing guard, The_audit_schema_carries_no_pii, asserts on column names,
so a BSN inside a column called Resource could never fail it. Added
No_audit_row_carries_a_subjects_bsn, which drives a denied reveal as a
non-default subject and scans every string field of every row for that BSN
and for DemoOwner — asserting on the two BSNs actually in play rather than a
\d{9} shape, since a hex correlation id can hold nine digits by chance.
Verified it goes red when only the Program.cs line is reverted.
AuditEntry.Actor on document audit rows holds a raw BSN too; that is a
different store and stays with RB-04.

Persist the security-relevant events (authz denials + BIG-nummer reveal/step-up) into a
data-minimised EF table (AuthzAuditEntry: At/Action/Resource/Decision/Role/CorrelationId —
never a name/BSN/value), extending the DocumentStore AuditEntry pattern (migration AuthzAudit).
AuditAuthz now persists via AuthzAuditStore.Record alongside its log line. GET /admin/audit
(admin-gated by the existing CasesAdmin) returns the trail newest-first. +3 backend tests incl.
a schema-carries-no-PII reflection test. Typed client regenerated (audit() + AuthzAuditDto);
no FE consumer yet (a future audit view must add the ROLE_AWARE prefix). Finishes WP-42's audit half.
