# Slice I7 — flat collision closeout
|
|
|
|
## Result
|
|
|
|
Modern Runtime Slice I is complete. Production collision consumes the
|
|
immutable prepared flat representation exclusively, per-resolve scratch is
|
|
retained and reset-complete, and no parsed DAT collision graph remains in
|
|
stable gameplay state.
|
|
|
|
The two production cutover commits are:
|
|
|
|
- flat-authoritative traversal:
|
|
`068a06518dd710ca5e7f166754cbb7789ca1ed0f`;
|
|
- parsed-graph removal:
|
|
`82f8d4f82e24ad85042ac3e25c4f6464bebce758`.
|
|
|
|
Exact rollback commands:
|
|
|
|
```text
|
|
git revert 82f8d4f82e24ad85042ac3e25c4f6464bebce758
|
|
git revert 068a06518dd710ca5e7f166754cbb7789ca1ed0f
|
|
```
|
|
|
|
Revert graph removal first. Do not revert the I3 prepared-package, I4
|
|
flat-traversal, or I5 publication work unless evidence implicates those
|
|
layers.
|
|
|
|
## Production ownership after removal
|
|
|
|
- `PhysicsDataCache` publishes immutable flat GfxObj, Setup, CellStruct, and
|
|
EnvCell topology records directly.
|
|
- Stable `GpuWorldState` strips temporary `PhysicsDatBundle` source material.
|
|
- Near `LandblockBuild` payloads discard Environment/GfxObj raw collision
|
|
graphs after their immutable flat closure is built.
|
|
- Live objects publish through the same strict prepared source.
|
|
- Graph constructors remain only as explicit test, bake, and equivalence
|
|
oracles. Production has no graph fallback and no sampled referee.
|
|
- The single validated `acdream.pak` mmap remains the production render and
|
|
collision source.
|
|
|
|
This is a storage/ownership change only. Collision comparisons, traversal
|
|
order, source float bits, retail thresholds, cell semantics, and authoritative
|
|
game behavior did not change.
|
|
|
|
The retail divergence register was audited. No row was added or retired:
|
|
Slice I changes the representation and lifetime of already ported collision
|
|
data without introducing a behavior deviation.
|
|
|
|
## Automated evidence
|
|
|
|
- Release build: pass with zero errors and zero warnings.
|
|
- Complete Release solution: 8,413 passed / 5 skipped.
|
|
- Focused Core collision, doors, doorway, cellar/ramp, jump, projectile, and
|
|
allocation gate: 154 passed.
|
|
- Focused App camera/projectile gate: 47 passed.
|
|
- Player, grounded walkable publication, remote, projectile, and camera
|
|
profiles: 0 B/resolve.
|
|
- Direct flat `CellSurface`, walkable-plane, behaviorless-cell, stable-state
|
|
stripping, and production graph-residency fixtures pass.
|
|
|
|
## Connected lifecycle/reconnect gate
|
|
|
|
Report:
|
|
`logs/connected-world-gate-20260725-182242/report.json` in the exact-binary
|
|
gate worktree.
|
|
|
|
- Source and binary:
|
|
`82f8d4f82e24ad85042ac3e25c4f6464bebce758`.
|
|
- Result: PASS; two graceful exits; zero failures.
|
|
- Six capped checkpoints plus one fresh-process uncapped reconnect passed.
|
|
- Parsed collision graph counts were `0/0/0` at every checkpoint.
|
|
- Flat GfxObj/Setup/cell residency remained populated, including:
|
|
- capped login: `168/112/71`;
|
|
- Rynthid: `384/262/790`;
|
|
- Facility Hub: `436/272/279`;
|
|
- Holtburg after dungeon: `761/415/531`;
|
|
- fresh uncapped reconnect: `167/103/59`.
|
|
- Publication, retirement, upload, warmup, and class backlogs converged.
|
|
|
|
The 25 world-edge misses are the route's existing expected diagnostic, not a
|
|
new collision failure.
|
|
|
|
## Connected canonical nine-stop gate
|
|
|
|
Report:
|
|
`logs/connected-r6-soak-20260725-182823.report.json` in the exact-binary gate
|
|
worktree.
|
|
|
|
- Result: PASS; graceful exit; zero failures.
|
|
- All nine portal checkpoints materialized and stabilized.
|
|
- Parsed collision graph counts were `0/0/0` at all nine checkpoints.
|
|
- Flat cell residency covered Caul, Sawato, Rynthid, Aerlinthe, and Holtburg,
|
|
including 790 cells at Rynthid and 531 at Holtburg.
|
|
- Movement, jump/fall, combat/projectile, portal, dungeon, revisit, and
|
|
authoritative server-echo checks passed.
|
|
- Final publication, retirement, worker, destination, control, unload,
|
|
near/far, staged-upload, and composite-warmup backlogs were zero.
|
|
|
|
The known route warnings were limited to a Caul visible-workload delta of two,
|
|
an eleven-particle plateau delta, 32 optional missing-DAT VFX diagnostics, and
|
|
the 25 expected world-edge misses.
|
|
|
|
## Measurement boundary
|
|
|
|
The user accepted collision correctness under RDP. The RDP nine-stop route
|
|
also showed a bounded final plateau near 1.93 GiB working set while carrying
|
|
observer/automation state, below the earlier dual-representation diagnostic
|
|
route's roughly 2.06 GiB final Caul working set. Those are not controlled
|
|
ordinary-client measurements, so no exact performance percentage is claimed.
|
|
|
|
Absolute post-removal CPU, GPU, frame-time, and ordinary-process memory
|
|
comparison remains deferred to the next physical-display performance pass.
|
|
That deferral does not weaken the deterministic, connected, ownership, or
|
|
resource-lifetime acceptance above.
|
|
|
|
## Next execution point
|
|
|
|
Slice J1 begins the borrowed-view, typed-command, ordered-event, clock, and
|
|
lifecycle contract layer in `AcDream.Runtime`. It must adapt the current
|
|
canonical owners first; it may not create a second gameplay world or add a
|
|
frame of graphical input latency.
