"""Web-management API surface: project/host CRUD, enqueue endpoints, and admin gating.

The conftest sets AUTH_TOKEN=test-token and SHARED_CONTEXT_WRITE_TOKEN=shared-token with no
ADMIN_TOKEN, so the effective admin token is the global test-token. The shared-token is a
valid-but-not-admin bearer: it passes require_auth (reads) but not require_admin (writes),
which is exactly what we use to prove the gate."""
