# Slice J6.2 — canonical reveal-generation ownership
|

|
|
**Date:** 2026-07-26
|
|
**Production commits:** `a6860d5563ae845a2cbb916abacf2b4aee515cdb`,
|
|
`acb845d812574206da1693fb379fec8a6f175fcb`
|
|
**Exact rollback, newest first:**
|
|
|
|
```text
|
|
git revert acb845d812574206da1693fb379fec8a6f175fcb
|
|
git revert a6860d5563ae845a2cbb916abacf2b4aee515cdb
|
|
```
|
|
|
|
## Outcome
|
|
|
|
`AcDream.Runtime.World.RuntimeWorldTransitState` now owns one canonical
|
|
login/portal reveal lifetime:
|
|
|
|
- monotonically increasing generation and exact destination cell;
|
|
- typed destination-readiness acknowledgement and atomic accepted latch;
|
|
- materialization and world-simulation availability;
|
|
- normal-world viewport observation;
|
|
- completion, cancellation, and session reset;
|
|
- the retail five-second wait cue;
|
|
- portal materialization count and invariant diagnostics.
|
|
|
|
`WorldRevealLifecycleTelemetry` and its App snapshot were deleted. App's
|
|
`WorldRevealCoordinator` now reports graphical readiness and performs
|
|
streaming/render-resource, selection, audio, and viewport side effects over
|
|
the same Runtime owner. `WorldGenerationAvailabilityState` is a read-only
|
|
projection and `CurrentGameRuntimeViewAdapter` borrows the Runtime portal view
|
|
directly instead of reconstructing it.
|
|
|
|
Runtime rejects stale generations, wrong destination cells, invalid
|
|
indoor/radius shapes, early materialization, early viewport reveal, premature
|
|
completion, and post-cancel work. Accepted readiness is sticky: graphical
|
|
readiness is a sampled host fact and may legitimately fall after Runtime has
|
|
accepted the atomic destination edge.
|
|
|
|
## Retail ordering
|
|
|
|
- `SmartBox::TeleportPlayer @ 0x00453910`
|
|
- `SmartBox::UseTime @ 0x00455410`
|
|
- `gmSmartBoxUI::EndTeleportAnimation @ 0x004D65A0`
|
|
|
|
The Runtime transition preserves retail's ordering: destination
|
|
materialization resumes world simulation while portal space still covers the
|
|
world; the normal viewport is observed later; completion follows the authored
|
|
WorldFadeIn/LoginComplete tail. No timeout or forced reveal was introduced.
|
|
|
|
## Automated evidence
|
|
|
|
- Runtime: 349 passed.
|
|
- App: 3,716 passed / 3 skipped.
|
|
- Complete solution: 8,626 passed / 5 skipped.
|
|
- Release build: zero errors; 17 pre-existing test-project warnings tracked by
|
|
issue #228.
|
|
- Ownership/source guards: one production Runtime transit construction, no App
|
|
lifecycle owner, no reconstructed portal view.
|
|
- Adversarial fixtures: wrong/stale generation, wrong destination, malformed
|
|
readiness, reordered edges, duplicate acknowledgement, post-ready sampling,
|
|
supersession, cancellation, session reset, generation reuse, two-instance
|
|
isolation, unhydratable destination, and throwing diagnostics.
|
|
|
|
One cold parallel full-suite run tripped the existing
|
|
`PortalProjectionTests.ProjectToClipLease_ReusesPooledWorkWithoutResultArrays`
|
|
allocation threshold by 2,008 bytes. The test passed immediately in isolation
|
|
and the complete suite then passed unchanged.
|
|
|
|
## Connected evidence
|
|
|
|
Accepted report:
|
|
`logs/connected-world-gate-20260726-171724/report.json`
|
|
|
|
The report records exact source and embedded binary commit
|
|
`acb845d812574206da1693fb379fec8a6f175fcb`.
|
|
|
|
- Capped process: 243.942 seconds, six checkpoints, graceful code-zero exit.
|
|
- Uncapped fresh-process reconnect: 61.625 seconds, one checkpoint, graceful
|
|
code-zero exit.
|
|
- Route: fresh login, Aerlinthe, Rynthid world edge, Facility Hub dungeon,
|
|
Holtburg, Aerlinthe revisit, then fresh-process reconnect.
|
|
- Failures: zero.
|
|
- Reveal invariant failures: zero.
|
|
- Expected warning: 25 instrumented world-edge landblock misses.
|
|
|
|
The earlier report
|
|
`logs/connected-world-gate-20260726-171020/report.json` is deliberately
|
|
rejected. It proved that graphical readiness may fall after accepted
|
|
materialization and exposed an incorrect diagnostic classification in
|
|
`a6860d55`; `acb845d8` keeps the accepted latch but treats later sampled
|
|
readiness as non-authoritative.
|
|
|
|
No new retail divergence was introduced.
