 | Landblock presentation | **Complete** | `LandblockBuildFactory` owns the captured-origin DAT transaction; concrete render/physics/DAT-static publishers and `LandblockPresentationPipeline` own typed-meter publication and exact retryable retirement. `StreamingController` owns stable destination/control/unload/Near/Far queues and destination reservation. CPU mesh-cache restaging requires an exact live owner. `StreamingOriginRecenterCoordinator` serializes old-window retirement with teleport/session origin lifetimes. `GameWindow` retains construction and one pipeline field only (`c79d0a49`, closeout `4a205a3e`; Slice E closeout `91e82c3c`). |
 | Render-frame orchestration | **Complete** | `RenderFrameOrchestrator` owns the GPU-flight, resource, world/PView/shared-alpha, private-presentation, diagnostics, screenshot, and recovery graph. `GameWindow.OnRender` takes one logical window-size snapshot and performs one immutable handoff (`9d7df1bf`). |
 | Unified `GameEntity` | **Slice J complete** | Canonical identity, retained-object lifetime, direct views, ordered entity/object deltas, gameplay state, action/combat/magic/movement/physics/remote/projectile simulation, world environment, reveal/transit truth, and host acknowledgement share failure-safe Runtime owners while exact graphical sidecars stay in App. One `GameRuntime` composes the graph. `RuntimeGenerationReset` is the sole retryable canonical-generation reset for graphical and no-window hosts; the deterministic direct host proves lifecycle, commands, portal, reconnect, GUID reuse, fault recovery, isolation, and terminal convergence without presentation assemblies (`a9a822f2`). |
-| Headless host | **Slice K0 complete; K1 active** | `AcDream.Headless` references only Runtime. Its strict CLI validator, dependency closure, loaded-assembly guard, and Windows/Ubuntu CI establish a production process that cannot acquire App, UI, GL, native-window, or audio ownership (`aada8a37`). |

Portable paths/config/credentials, deterministic command/event scheduling, shared immutable content, exact per-session identity, failure quarantine, reconnect, resource telemetry, 1/5/10/30-session isolation, two-hour simulated endurance, and the exact two-account native-Linux connected soak pass through `776482da`. |
