Modern Runtime headless continuation

Current checkpoint

Slice J is closed. Slice K0-K3 are closed; K4 implementation is complete through 776482da, with the exact connected terminal gate active.

K3's production closeout commit is 3f340125. Its automated predecessors are 12b500d3, 9569dadb, and b6547ff3.

K4 commits after the telemetry/CPU checkpoint are:

• 97c174fb: 1/5/10/30-root content sharing, same-GUID isolation, portal, reconnect, and 480,000-frame-per-root two-hour simulated endurance;
• bd236ce5: death during the endurance route plus five randomized 30-session cancellation-edge runs;
• 776482da: committed diagnostic-only 30-session resource ceilings, per-sample evaluation, named failures, and exact running/terminal ownership checks.

Windows and native Ubuntu Headless tests pass 67/67; the complete Release suite passes 8,784 / 5 skips.

The Windows visible-terminal host and native Linux/WSL host both connected to local ACE without loading presentation assemblies. Linux completed the Aerlinthe/Caul/Rynthid/lifestone route, accepted external teleallto destinations, remained visible to a retail observer, turned and ran smoothly, and shut down through ACE-confirmed graceful logout. The user accepted the observer movement gate on 2026-07-27.

Important connected correction

RuntimeLiveEntitySessionController passes the exact accepted PositionTimestampDisposition to the direct world projection.

• Normal Apply echoes update canonical state but do not reset the local headless movement controller.
• ForcePosition uses BlipPosition, preserves active movement semantics, and sends an immediate autonomous-position acknowledgement.
• A real teleport performs one full synchronization from PrepareDestination.

Do not reintroduce full local-player synchronization for every accepted Position packet; it stops movement and causes retail observers to see repeated run/snap-back rubberbanding.

Collision [snap] output is high volume and must remain behind the explicit PhysicsEngine.DiagnosticLog sink.

Automation seam

Graphical automation and headless policies use IGameRuntimeView, IGameRuntimeCommands, IRuntimeEventSource, and the same RuntimeLocalPlayerFrameController/outbound serializers. The route and observer policies are diagnostic consumers, not a second bot world or movement implementation.

The user requires optional direct single-session CLI launch with -user/-password or the long-form aliases. Multi-session configuration continues to use credential providers.

Next work

Finish K4 from docs/plans/2026-07-26-modern-runtime-slice-k.md:

1. keep the exact 776482da two-account Rynthid process running while the user observes it;
2. verify every periodic sample remains inside the committed envelope with no fault/reconnect/lease debt;
3. stop it gracefully and require a final disposed sample with two converged Runtime roots, zero entities/inventory/host leases, disposed shared content, and withinCeilings=true;
4. close Slice K and begin Slice L Linux graphical/platform work.

Final K3 automated counts: Runtime 412, Headless 47, App 3,722 / 3 skips, complete Release 8,764 / 5 skips.
