/**
 * DC-165: site/product uniformity bundle — tests.
 *  1. fleet is a gated premium feature (403 free / pass premium, and the
 *     gate is mounted at ROUTER level so new sub-routes inherit it).
 *  2. offline activations minted before 'fleet' existed are forward-
 *     migrated on load (creator lifetime key case).
 *  3. GET /api/v1/capabilities returns the running build's ground truth
 *     derived from source modules (no drift by construction).
