RFC §4 V3 compliance — cross-tenant access to FormSubmissionActionFailure
endpoints returns 404, not 403, to prevent resource-existence
enumeration. The FormSubmissionActionFailurePolicy is the single tenant
gate; these tests assert the route-level integration end-to-end.
Production-code finding (in scope per "security gaps zijn altijd urgent"):
the orgIndex endpoint had a real IDOR gap. Original implementation called
`Gate::authorize('viewAny', ...)` which permits any org_admin in any org,
then filtered the result set by the URL's `{organisation}` param. orgB's
admin hitting `/organisations/{orgA}/form-failures` would get back orgA's
failures — leakage.
Fix:
- New policy method `viewAnyInOrganisation(User, Organisation)` that
requires super_admin OR org_admin on THIS specific organisation.
- Controller `orgIndex` calls `authorizeViewAnyInOrgOrNotFound()` which
translates a denied policy → 404 (matches the show/retry/resolve/dismiss
pattern).
- viewAny on the class level stays as the platformIndex gate (super_admin
+ any-org_admin enumeration is acceptable on the platform endpoint
because the role middleware already restricts to super_admin).
Test coverage (24 tests, all passing):
- 5 org-scoped endpoints × cross-tenant scenarios (all return 404)
- 5 platform endpoints × role-class scenarios (org_admin gets 403, never 404)
- Edge cases: soft-deleted parent submission, invalid ULID format,
non-existent ID, unauthenticated, authenticated-without-role on org
The 403 vs 404 distinction matters: role-gated endpoints return 403
(auth-class — "not allowed in this room"); ownership-gated endpoints
return 404 (IDOR-class — "this room doesn't exist for you").

About Laravel
Laravel is a web application framework with expressive, elegant syntax. We believe development must be an enjoyable and creative experience to be truly fulfilling. Laravel takes the pain out of development by easing common tasks used in many web projects, such as:
- Simple, fast routing engine.
- Powerful dependency injection container.
- Multiple back-ends for session and cache storage.
- Expressive, intuitive database ORM.
- Database agnostic schema migrations.
- Robust background job processing.
- Real-time event broadcasting.
Laravel is accessible, powerful, and provides tools required for large, robust applications.
