IIdentityProvider.Resolve returned a non-nullable CallerIdentity, so
the interface could not express "no identity" - StubIdentityProvider
was forced to invent one for any request carrying no credential at
all. Consequence: a production behandelportal build sends no
X-Medewerker header (medewerkerInterceptor is dev-only), so it used
to authenticate as the seeded citizen, role drafter - failing closed
on backoffice capabilities but open on every citizen-scoped endpoint,
including CanRevealBigNummer.
Resolve now returns CallerIdentity?. StubIdentityProvider keeps a
non-nullable return type (a valid narrower override) since it never
itself has "no identity" to report - it is registered only under
IsDevelopment() now. Production registers nothing and throws an
InvalidOperationException immediately during startup instead: there
is no real DigiD/employee-SSO provider in this POC yet, so a
misconfigured Production deploy must fail before serving a single
request, not resolve one per request. The identity-resolution
middleware turns a null resolution into a 401 rather than passing it
downstream.
Added StubIdentityProviderTests.Never_returns_null_even_with_no_headers_at_all
and ProductionIdentityProviderTests, which builds its own
WebApplicationFactory<Program> with UseEnvironment("Production") and
asserts startup throws. Verified both new tests fail red against the
pre-fix code.
RB-01's residual (GET /uploads/{id}/content reached via plain browser
navigation, no identity header) is confirmed unchanged in Development
and its Production consequence is written up in
implementation/rb-09.md for whoever lands the real identity provider -
no signed-URL/cookie scheme was designed here, per scope.

Splits backend CallerIdentity into the two ADR-0002 §3 actor kinds
(ZorgverlenerCaller/MedewerkerCaller), a stub X-Medewerker/X-Rollen header
path mirroring WP-53's citizen stub, and Authz.CanBeoordelen as the first
medewerker capability — backend-only, no consumer until WP-64. Also fixes
the backlog README's stale WP-61 status (done, but table said todo).

Replaces the hardcoded DocumentStore.DemoOwner and the static ZgwOptions
UserId/UserRepresentation with one per-request CallerIdentity, resolved by a
pluggable IIdentityProvider (StubIdentityProvider reads X-Role/X-Subject
today; a real OIDC/DigiD provider swaps in without touching any consumer).
- Domain/Authorization/{CallerIdentity,IIdentityProvider,StubIdentityProvider}.cs
+ a resolution middleware in Program.cs, right after correlation-id.
- Authz.ResolvePrincipal(ctx) keeps its signature (now reads ctx.Caller().Role),
so its ~15 call sites needed no changes.
- Every endpoint that passed DocumentStore.DemoOwner to a store now passes
ctx.Caller().Bsn.
- ZgwTokenProvider gains Mint(CallerIdentity) alongside the original Mint()
(kept for calls not tied to one citizen); ZgwHttpClient threads an optional
caller through to pick the right overload.
- IZaakSource gains ListMyCases(caller, now) — the citizen-scoped read
OpenZaakZaakSource backs with ZGW's rol__...__inpBsn filter. GET /applications
now routes through it instead of ApplicationStore directly, closing the last
"reads a static store" gap for a citizen-facing endpoint.
Backend 159/159 tests (+8, incl. an HTTP-level two-identity scoping proof),
npm run ci green, no api-client drift.
