 The matchmaking UI now exposes that retained replay through its existing action button as `Retry Request` while a heartbeat, cancellation, or proposal action has a retryable failure. Terminal, authentication, and revision-conflict paths remain ineligible, so the button cannot issue a stale blind command.
 
 The control plane now exports bounded Prometheus-compatible API request counters and latency summaries at `GET /metrics`, with fixed operation/status labels and no event-stream wrapping. Production and testkit services wire the collector; adversarial tests verify unknown paths cannot inject label cardinality or leak URL secrets, and full Go/race/vet checks pass. Durable SLO dashboards and alert routing remain operational work.

+`make verify-multiplayer-local` now provides one cloud-free regression gate for the current implementation: the complete Go suite, the Godot harness, OpenAPI parsing, and the migration/Fleet/Kubernetes/supply-chain checks. It fails clearly when the configured Godot executable is unavailable and does not weaken or replace the existing Phase 6/ENet gates; PostgreSQL, Redis, Steam, Agones, and multi-process Internet gates remain separate.
