# Modern Runtime headless continuation
|
|
|
|
## Current checkpoint
|
|
|
|
Slice J is closed. Slice K0-K3 are closed; K4 is active.
|
|
|
|
K3's production closeout commit is `3f340125`. Its automated predecessors are
|
|
`12b500d3`, `9569dadb`, and `b6547ff3`.
|
|
|
|
K4's resource-telemetry/CPU checkpoint is `cb512fd0`. It adds one
|
|
process-scheduler observation deadline, structured process/managed/session/
|
|
content/scheduler metrics, exact post-disposal convergence reporting, startup
|
|
deadline rebasing, and the Linux sub-millisecond busy-wait correction. It does
|
|
not add per-session timers or workers. Windows and native Ubuntu Headless
|
|
tests pass 56/56; the complete Release suite passes 8,773 / 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
|
|
|
|
Execute K4 from `docs/plans/2026-07-26-modern-runtime-slice-k.md`:
|
|
|
|
1. after the user finishes observing the current two clients, restart on exact
|
|
`cb512fd0` or a documented descendant;
|
|
2. prove cadence-bounded wait count, zero startup catch-up, reduced CPU, and
|
|
exact teardown convergence under matched one- and two-account workloads;
|
|
3. derive and commit numeric per-session/process ceilings;
|
|
4. run automated 5/10/30-root stress and endurance gates; the connected scale
|
|
gate is presently limited to the two available local ACE accounts;
|
|
5. prove stable plateaus and exact teardown convergence;
|
|
6. close Slice K, then start 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.
