POST /registrations passed its Documents list straight to Submit, which calls
DocumentStore.Link on every digital documentId in it — and linking a document
blocks its owner from ever deleting it (DeleteOwned returns 409 Linked). That
path had no ForeignIds ownership check, so any authenticated citizen could
post another citizen's document id and permanently block them from deleting
their own diploma scan. POST /applications/{id}/submit, the endpoint actually
in use, has had that guard since it was written.
Deleted rather than guarded: the endpoint is dead. No frontend caller, and
the whole registratie flow goes through /applications/{id}/submit.
RegistratieRequest went with it, and so did SubmissionRules.RejectRegistratie
— reachable only from here, and contradicted by the live path, which treats a
handmatig diploma as "does not auto-approve" rather than a 422 rejection. Its
own message said as much while being returned as a rejection. That last part
is a judgement call beyond the ticket's wording; reverting the two
SubmissionRules hunks restores it in isolation.
Coverage moved rather than vanished: the problem+json shape assertion is now
on /change-requests (the other endpoint on the same Submit helper), and the
linked-delete 409 test goes through the real submit path.
swagger.json, the generated client and the behaviour spec regenerated.

GET /uploads/{documentId}/content took only (string documentId) — no
HttpContext, so no authorization was possible. It streams diploma and
identity scans, protected by GUID unguessability alone, while DELETE on the
same resource has always been owner-scoped. GET /uploads/status had the same
shape and confirmed whether any client-chosen localId exists, plus its
documentId.
Both now take HttpContext. Content is readable by the owning
ZorgverlenerCaller or a caller passing Authz.CanBeoordelen — matched on the
caller kind rather than branched on a boolean, because ctx.Zorgverlener()
throws for a MedewerkerCaller and the behandelportal's beoordeling screen is
a legitimate reader. Status is scoped to ctx.Zorgverlener().Bsn via a new
owner parameter on DocumentStore.ByLocalIds (one call site).
404, not 403, on both: a foreign document id must not be distinguishable
from one that never existed, and a foreign localId reads back as "unknown".
Residual, recorded in the implementation note: both callers reach the URL as
a plain browser navigation (<a href> / previewUrl), which carries no identity
header and no interceptor, so StubIdentityProvider resolves it to the seeded
citizen. That is BIO-002 and belongs to RB-09; the links keep working today
only because one citizen owns every document in the POC.
