f9b68f8f2a feat(rendering): complete current-path render referee
Extend the non-drawing oracle through ordered PView routes, dispatcher visibility and final instance payloads, and accepted retail selection parts. Lifecycle artifacts can now referee the later shadow scene without influencing production visibility or draw decisions.

dbaea19269 test(streaming): decouple lifecycle assertions from wall time
Use an explicit generous work profile in multi-operation behavior tests. Their contract is failure isolation and retirement ordering, not whether cold JIT work fits the production two-millisecond frame budget.

b2b67341ac feat(rendering): establish current-path scene referee
Capture deterministic, landblock-aware fingerprints from the accepted partition only during lifecycle automation. This gives the F/G shadow scene an independent oracle without changing normal draw decisions or adding disabled-path per-entity cost.

91e82c3c68 fix(streaming): prepare quiesced destination entities
Separate loaded spatial residency from the world presentation gate so destination live objects acquire mesh owners behind portal space while drawing and simulation stay quiesced. Prevent unowned CPU-cache hits from recreating stale GPU staging work.

Correct whole-frame GPU timestamps so they bracket only the accepted render transaction and associate delayed query results with the owning CPU frame. Add route-wide frame-history summaries, fixed-camera screenshot comparison, process counters, contention traces, a pinned Arwic workload, and credential-safe launch disclosure.

7b456b49d6 perf(diag): per-frame history export + checkpoint LOH/cache counters + soak capped mode (2026-07-24 audit review)
An adversarial performance review found our own instruments cannot
measure the project's own performance gates:

- FrameProfiler aggregated CPU/GPU/alloc/stage samples into ~5-second
  windows and reset the ring buffers after each report, so route-wide
  p50/p95/p99 distributions across a whole soak could not be
  reconstructed after the fact. ACDREAM_FRAME_HISTORY=<path> now opts
  into a separate per-frame history (one record per frame, ~72
  bytes/record, accumulated in memory with zero frame-thread I/O) that
  a shutdown-only Dispose() writes as CSV. The aggregated [frame-prof]
  report format and its existing metrics are unchanged.

- The canonical checkpoint JSON tracked cache residency (entry/byte
  counts) but never LOH size/fragmentation, process-wide allocated
  bytes, or cache hit/miss/eviction traffic — a committed audit JSON
  showed 65% LOH fragmentation that no tracked instrument recorded,
  and "does a revisit portal hit or miss the caches" was unanswerable
  from an artifact alone. WorldLifecycleResourceSnapshot now carries
  loh_size_bytes/loh_fragmentation_bytes (GCMemoryInfo.GenerationInfo
  index 3), process_total_allocated_bytes (GC.GetTotalAllocatedBytes),
  and Interlocked hit/miss/eviction counters for the CPU mesh cache,
  decoded-texture cache, and the four bounded DAT-object caches
  (portal/cell/highRes/language, aggregated).

- run-connected-r6-soak.ps1 unconditionally forced
  ACDREAM_UNCAPPED_RENDER=1 with no capped mode, while its sibling
  lifecycle-gate script correctly gated it behind a switch. Added
  -Uncapped (default capped, matching the sibling script's pattern),
  fixed the stationary dwell (12s -> 26s, past the 25s
  LiveEntityLivenessController deadline the adjacent comment already
  cited), and now write an env-disclosure.json into the automation
  artifact directory before every launch listing every ACDREAM_* var
  the script sets plus -Uncapped, since the prior audit could only see
  ACDREAM_DUMP_MOVE_TRUTH and nothing else was ever recorded anywhere.

Cache counters are wired via the existing composition path
(ObjectMeshManager already owns the CPU mesh cache and the mesh
extractor directly; content.Dats is threaded into
WorldLifecycleResourceSnapshotSource the same way every other
composition consumer receives it). The DAT-object cache lives behind
IDatReaderWriter, a third-party interface from the DatReaderWriter
package that cannot be extended; RuntimeDatCollection (the one
production implementation) exposes the aggregate stats directly and a
pattern match reads them, degrading to zero for any test double —
no new static registry was introduced (GpuMemoryTracker remains the
one precedented process-wide static).

1e9031e7b7 fix(audio): bound decoded-wave and AL-buffer caches (2026-07-24 audit review)
Two audit-verified caches grew monotonically for process lifetime, which is
fatal for the 30-bot long-uptime headless-fleet goal:

- DatSoundCache._waves (Core) memoized every decoded PCM WaveData forever
  in a bare ConcurrentDictionary — no LRU, no byte budget.
- OpenAlAudioEngine._bufferByWaveId (App) retained a native OpenAL buffer
  copy of the same PCM per wave id until engine disposal — a second,
  independent unbounded cache.

DatSoundCache now bounds payload residency with a 32 MiB byte-budget LRU
(decoded PCM waves run ~100-500 KB each, so this holds a comfortable
working set). Missing/unsupported-format waves are memoized separately in
an unbounded-but-cheap negative-result set (bounded by the finite Wave dat
id space) so they can never compete with or get evicted alongside payload
entries. Concurrent first-touch decodes of the same wave id are deduped
via a shared Lazy<T> so racing callers don't pay for WaveDecoder.Decode
twice. AcDream.Core cannot reference AcDream.Content (code-structure rule
2), so the LRU is a local reimplementation mirroring
BoundedDatObjectCache/DecodedTextureCache's shape rather than a shared
dependency.

OpenAlAudioEngine._bufferByWaveId now bounds native buffer residency with
a 48 MiB byte-budget LRU (AlBufferBudgetTracker), evicting least-recently-
used buffers once oversized. alDeleteBuffers fails on a buffer still
attached to a source, so eviction queries live AL per-source state
(GetSourceInteger.Buffer) rather than tracking a second, easily-stale
copy — several call sites (Play3DWave, PlayUiWave) set a source's buffer
directly. The buffer EnsureBuffer just created is explicitly protected
from its own eviction pass, since the caller hasn't attached it to a
source yet at that point. Evicted waves simply replay through
DatSoundCache -> EnsureBuffer on next use, identical to a first play.

Verified before implementing: AudioHookSink is the only GetWave caller
(single per-frame render-thread path per AnimationHookRouter's own
threading doc), and PcmBytes is read only at DatSoundCache.Admit (byte
accounting) and EnsureBuffer's first-upload branch — confirmed dead after
AL upload on the steady-state replay path, so bounding either cache
independently is correctness-safe; a cold replay after both evict simply
falls back to a full re-decode + re-upload, identical to a first play.

AlBufferBudgetTracker's eviction/budget decision is extracted as pure
logic (no AL dependency) specifically so it's unit-testable: the existing
OpenAlResourceLifetimeTests fake exposes a null AL, which short-circuits
every native buffer call before it runs, so the engine's actual AL wiring
isn't testable headless.

Tests: 9 new DatSoundCacheTests (Core.Tests) covering eviction order, byte
accounting, negative-result memoization, oversize-single-entry handling,
and concurrent-access smoke tests; 10 new AlBufferBudgetTrackerTests
(App.Tests) covering the pure LRU/budget/protection logic. Full suite:
3214/2 skip (Core.Tests), 3471/3 skip (App.Tests) plus one pre-existing,
unrelated failure (LandblockBuildOriginTests.FarLoad_..., reproduces
identically with these changes stashed out — landblock streaming, not
audio).

60bc313917 perf(content): CellStruct clone guard, solid-color texture cache, drop double ToList (2026-07-24 audit review)
Three small verified MeshExtractor.cs fixes from an allocation audit:

- CellStruct clip-map clone guard: the CellStruct polygon-surface path
  cloned decoded texture data unconditionally before applying clip-map
  transparency, even though the comment above it says "if we got this
  from the cache, we need to clone it." The GfxObj path already had the
  correct pattern (clone only when textureDataIsCached). Wired the same
  textureDataIsCached flag through CellStruct's TryGet/GetOrCreate/
  RetainOrUse call sites and gated the clone on it, matching GfxObj
  exactly — freshly-decoded arrays (the common case) now skip a
  redundant clone + BlockCopy.

- Solid-color texture cache: isSolid surfaces (Base1Solid / NoPos-
  stippled polys) allocated a fresh 32x32 RGBA array (4 KiB) on every
  polygon, even for repeated colors. Added a MeshExtractor-scoped
  ConcurrentDictionary<uint, byte[]> keyed by packed ARGB, bounded by
  distinct colors observed (a few hundred at most) rather than call
  volume. Traced every downstream consumer of the solid-color array
  (clip-map clone-guard, translucency clone-guard, GL upload, pak
  serialization) — none currently mutate a solid-color array in place,
  since isSolid is mutually exclusive with the texture-decode branch
  those guards live in — but wired textureDataIsCached = true at both
  call sites anyway so the existing clone-before-mutate machinery
  protects the shared array if that ever changes.

- Dropped the redundant .ToList() on both _dats.ResolveId(...) calls:
  DatCollectionAdapter.ResolveId already returns a materialized List<T>
  typed as IEnumerable; the immediate .OrderByDescending().FirstOrDefault()
  enumerates once, so the extra copy was pure waste.

Added SolidColorTextureCacheTests (dat-gated, matching suite convention)
exercising the new cache directly via internal visibility.

a4b1214e0f chore(render): delete dead ParticleBatcher chain (2026-07-24 audit review)
ParticleBatcher/ParticleEmitterRenderer/ActiveParticleEmitter (src/AcDream.App/Rendering/Wb/)
are an earlier WorldBuilder-derived particle-preview design with zero live call
sites: ParticleBatcher.Begin/AddParticle/Flush/End are only called from
ParticleEmitterRenderer.Render, which is only called from
ActiveParticleEmitter.Render, and `new ActiveParticleEmitter` has zero call
sites anywhere in the repo (verified by grep across src/tests/tools). The only
wiring was OpenGLGraphicsDevice.ParticleBatcher (property + null-init + Dispose)
and a single assignment in WbMeshAdapter.cs.

ParticleBatcher's constructor unconditionally allocated a ParticleInstance[65536]
managed array (~3.5 MiB) plus a matching GPU instance buffer, a shader, a VAO,
and 3 more GL buffers, none tracked by GpuMemoryTracker or ever drawn from.

ParticleEmitterRenderer's per-particle-type physics (Particle::Init vector-space
resolution, CalculatePosition integration) duplicates, without retail address
citations, what src/AcDream.Core/Vfx/ParticleSystem.cs already implements with
Particle::Init (0x0051c930) / Particle::Update (0x0051c290) citations and the
same ParticleType switch — the production path (ParticleSystem.cs +
AcDream.App/Rendering/ParticleRenderer.cs) supersedes it. No unique retail
knowledge is lost.

EmbeddedResourceReader.cs and the wb_particle.vert/frag shader sources are
deleted alongside it: EmbeddedResourceReader's own doc comment says it exists
solely so ParticleBatcher/ParticleEmitterRenderer can load WB-style shader
resource names, and GetEmbeddedResource had no other caller in the repo.

cf25330458 fix(net): survive transient socket errors in the receive loop (2026-07-24 audit review)
WorldSession.NetReceiveLoop wrapped its entire while loop in a single
try/catch, so ANY non-timeout SocketException permanently killed the
background receive thread: the catch block at the loop's end was empty
(misattributed the error to "socket closed during shutdown"), and the
finally called _inboundQueue.Writer.TryComplete(), which silently and
irrecoverably stopped all inbound processing for the rest of the
session — no log line, no recovery path, and LiveSessionHost.Reconnect
has zero production callers to notice.

The realistic trigger is a well-known Windows UdpClient quirk: an ICMP
"port unreachable" reply to an EARLIER Send (e.g. against a stale ACE
session that already tore down its socket) surfaces as a
WSAECONNRESET SocketException on this socket's NEXT, completely
unrelated Receive call. NetClient.Receive already swallows the
expected SocketError.TimedOut heartbeat case; anything else reaching
WorldSession was a real, transient, per-datagram error being treated
as session-fatal.

Three changes, root-cause not a band-aid:

- NetClient's constructor now disables SIO_UDP_CONNRESET reporting on
  Windows, so a delayed ICMP error can't poison receives at all.
- NetReceiveLoop now catches SocketException PER ITERATION, logs it,
  and continues polling instead of exiting. The existing clean-shutdown
  paths (cancellation, ObjectDisposedException during Dispose) are
  unchanged — only the non-timeout-socket-error case that used to kill
  the loop is now recoverable.
- NetClient.Receive no longer calls the ReceiveTimeout setter (a
  setsockopt syscall) on every single call — only when the requested
  timeout differs from the last-applied value, cached in a new field.
  This was an unrelated but adjacent finding (4x/sec syscall churn at
  the 250ms heartbeat cadence) in the same audit.

No change to outbound wire behavior, ack cadence, heartbeat interval,
or datagram ordering — this is purely receive-loop resilience.

Tests: NetClientTests gained a SIO_UDP_CONNRESET construction smoke
test and two ReceiveTimeout-caching tests. A new
WorldSessionNetReceiveLoopResilienceTests drives the actual private
NetReceiveLoop method (via the existing internal
IWorldSessionTransport seam + reflection) with a scripted transport
that throws a non-timeout SocketException on the first call, proving
the loop survives it and keeps enqueueing subsequent datagrams — fully
deterministic, no real sockets. Full solution suite green: 3204/3206
Core, 3462/3465 App, 552/552 Core.Net (skips pre-existing).
