acdream had no ambient system: StartAmbient minted a handle and played
nothing. Retail's is a weighted-accumulation + timer-queue engine, not
looping voices. On every objcell change (24 m) CellManager::ChangePosition
rebuilds per-sound weights over the 3x3 landblock ring x 64 land cells
each, decoding each cell's terrain word through the region file's
terrain -> scene -> AmbientSTBDesc chain; playback is a min-heap of
absolute deadlines drained from the frame tick, where each pop fires a
one-shot and re-arms.
A continuous bed (base_chance == 0) is non-positional, crossfaded by its
share of the TOTAL weight, and re-fired every min_rate seconds — that
rate is the author's intended loop period, and re-firing is how retail
fakes a sustained bed with no looping voice, re-rolling the variant and
the crossfade each time. An intermittent one keeps its authored volume,
plays at a random accumulated compass bearing at min + (max-min)*t^2,
and is dice-gated. Indoors is silent by design: CEnvCell's contributor is
a folded ret and EnvCell carries no sound data.
The Opus review caught four bugs before this landed, one fatal:
- Cell offsets were built in ABSOLUTE world coordinates and differenced
against the listener's STREAMED-frame position, so every one of 576
offsets came out ~32 km, every contribution was culled, and the whole
feature was silent with nothing logged. Offsets are now landblock-local
the way Position::get_offset builds them, and the streamed-frame
position is carried separately for playback, where it belongs.
- The cell's weight was added to the shared denominator once per
DESCRIPTOR instead of once per CELL, dividing every bed's crossfade by
the table's entry count — enough to push a typical authored volume
under the 0.03 audibility floor.
- The drain used where retail's UseTime is strictly
below, so a descriptor authored with a zero rate re-armed at the same
instant and spun the frame forever.
- Arming only enqueued; retail's UpdatePlayQueue PLAYS and then re-arms,
so a newly audible ambient was silent for a full period after the
crossing that made it audible.
Also: beds now go through retail's single 16-voice priority pool rather
than acdream's UI pool (retail has one pool; parking beds in the UI pool
let an A4 portal cue chop one mid-wave and discarded the authored
priority), and CalcDir's in-block test is XY-only, since CalcWeight
includes Z on purpose and CalcDir excludes it on purpose.
Two behaviours are knowingly incomplete and registered rather than
guessed at slice end: TS-66 (sky-lit interiors should keep the outdoor
set) and TS-67 (contribution weight is computed in-plane). Retires TS-29.
The frame-loop hook is a typed IAmbientFramePhase, not a callback — the
first attempt used an Action<float> and the architecture guard
ExtractedUpdateOwners_DoNotRetainAnonymousCallbacks correctly rejected it.

Make every App composition phase borrow one GameRuntime, retire the duplicate view/event adapters, and dispose the root only after its graphical borrowers release. This preserves synchronous UI commands while giving shutdown one exact ownership ledger.

Move the canonical WorldSession generation, connect/enter/tick/stop transaction, inbound subscription owner, and retryable teardown acknowledgements into AcDream.Runtime. Keep App as a borrowing graphical host with a single inertable command projection and no mirrored session state.
Validated by 79 Runtime tests, 3,776 App tests with three existing skips, the Release solution build, and 8,428 complete Release tests with five existing skips.

Establish the J1 presentation-independent contract with instance-scoped clocks and generations, immutable borrowed views, typed generation-gated commands, normalized ordered diagnostics, and teardown acknowledgements. Route graphical startup plus press-time selection, movement, and combat through focused App adapters over the exact existing owners without adding a queue or mirrored world.
Validated by the Release solution build, 13 Runtime tests, 3,838 App tests with three existing skips, and the complete 8,424-test Release suite with five existing skips.

Inbound state continues while portal reveal blocks ordinary world simulation. Synchronize only the derived render projection after those hidden-frame network and command phases so the first revealed draw cannot observe a stale live transform, without advancing effects, particles, attachments, or lights.
Move the ordinary shadow-scene drain out of the conditional spatial reconciler and into an explicit final update-frame commit phase. This publishes deltas after streaming, network, teleport, camera, and conditional reconciles even while world simulation is quiesced.
Release gate: 3,733 App tests / 3 skips; 8,217 complete-solution tests / 5 skips.

Construct Slice F's non-drawing scene only for lifecycle automation, drain accepted static and live deltas at the final update boundary, and compare exact current-path fingerprints at cadence and checkpoints. Publish bounded mismatch, journal, index, digest, and memory evidence without changing normal launches or draw submission.
Release: 8,211 passed, 5 skipped.
Maintain packed render worksets as lifecycle deltas arrive and synchronize active animated statics without scanning the resident world. This keeps Slice F non-drawing while preparing exact spatial and feature queries for shadow comparison.
Release: 8,206 passed, 5 skipped.
Publish the retail blocking-for-cells edge before deferred recenter work, freeze old-world presentation/simulation/audio, and advance full-window retirement from exact metered entity and owner cursors. This removes synchronous portal teardown without allowing retained owners to remain observable.
Give terrain, sky, retained UI, portal preparation, and the update/render frame pair explicit single owners. Make shader, texture, text, bindless, and GL construction prefixes checked and retryable so partial failure cannot lose or replay resource ownership.

Reduce GameWindow.OnUpdate to one typed orchestration call and remove transitive window callbacks from teardown, liveness, teleport placement, live presentation, auto-entry, and entity packet routing. Preserve the frozen retail object/network order while making the production owner graph explicit and testable.
