// Tests for Task #524 — MR-H1 / MR-H2 / MR-M7.
//
// Coverage:
//  1. Unauthenticated GET /api/storage/objects/* → 401 (auth boundary).
//  2. Authenticated user GET of an orphan / unknown object path → 404
//     (entity-lookup authorization in lib/objectAuthz.ts denies orphans
//     so we don't leak which object UUIDs exist in storage).
//  3. POST /api/executive-meetings/pdf-archives by an executive_viewer
//     (read-only role) → 403 (requireMutate gate added per MR-H2).
//  4. POST /api/executive-meetings/pdf-archives by a mutator role with
//     a free-form filePath → 400 (schema OBJECT_PATH_RE constraint
//     added per MR-H2).
//  5. POST /api/executive-meetings/pdf-archives by a mutator role with
//     no filePath → 201 (regression: synthetic `print:<date>` path
//     still works, archive list is not blocked for legitimate users).
//  6. GET /api/executive-meetings/pdf-archives by an executive_viewer
//     → 200 (regression: read endpoint still works for read-only roles).
