 | 8.27 `[D:8.26]` | **IN PROGRESS.** Go supervisor package provides local-safe Agones REST discovery, validates assigned address/port data, injects dynamic `SDR_LISTEN_PORT`/`SDR_IP`, performs explicit process-ready probing and Ready transition; direct mode bypasses Agones | `server/supervisor/` covers allocated/direct startup, invalid endpoint rejection, dynamic endpoint/Ready ordering and authenticated drain; allocated Godot now supplies a loopback readiness/drain control surface and `agones_sdk.gd` supplies sidecar Health/Ready/Shutdown/annotation REST operations; metadata watch, real Agones annotation/shutdown confirmation and emulator integration remain |
 | 8.28 `[D:8.6,8.27]` | **IN PROGRESS.** Supervisor separates explicit process-ready from Agones Ready and never scrapes stdout; allocated mode refuses to mark Ready without a configured readiness probe | `server/supervisor/` tests prove Ready follows the probe and direct mode remains functional; `server_control.gd`, `agones_sdk.gd` and process-level smokes prove loopback `/ready`, `/health`, bearer-protected `/drain`, sidecar-shaped Health/Ready calls and drain admission fencing; detached-container and Health-reclaim integration remain |
 | 8.29 `[D:8.26,8.27]` | **IN PROGRESS.** Supervisor discovers and validates the Agones endpoint, propagates the actual dynamic `--port`, and exports `SDR_LISTEN_PORT`/`SDR_IP` only for Hosted-SDR while preserving an isolated ENet path | `server/supervisor/` tests cover invalid address/port rejection, dynamic port argument/env propagation and SDR-vs-ENet separation; real Agones dynamic/passthrough mapping, POP/cert/firewall/NAT and multi-match fixture remain |

 | 8.32 `[D:8.2,8.26,8.30]` | **IN PROGRESS.** Provider-neutral FleetAutoscaler baseline preserves a two-process Ready buffer, caps warm capacity, and leaves Allocated scale-down independent of the Ready floor; Fleet image references remain digest-pinned for current/rollback pre-pull | `deploy/k8s/base/fleet-autoscaler.yaml` and manifest tests cover Fleet ownership, Buffer policy and floor/cap invariants; regional on-demand node pools/failure domains, pre-pull rollout, warm-allocation p95/p99 and N+1 certification remain |
 | 8.33 `[D:8.26,8.32]` | **IN PROGRESS.** Fleet scheduling now requires on-demand capacity and spreads Ready processes across zones with skew 1; the autoscaler preserves the two-process Ready floor | `deploy/k8s/base/fleet.yaml` and manifest tests reject interruptible placement and single-zone concentration structurally; regional node pools, forced node-loss testing and measured N+1 headroom remain |
