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.
The reference hardware/display contract now keeps local and RDP populations separate and defines the screenshot and re-baseline rules needed by later prepared-content gates.

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).

(cherry picked from commit 1da2c33c875b41fa383dd79694ee2765f0e21896)
Replace scheduler-quantized software sleeps with a reusable Windows high-resolution deadline timer, expose pacing in the frame profiler, and make shutdown wake every persistent mesh worker without losing the shared signal.
Preserve retail alpha order while using a stable radix, skip duplicate deferred-alpha SSBO packing, pack light sets, cache static selection descriptors, and retire historical material groups at the whole-frame boundary. The fixed dense-Caul sample improved from roughly 9-12 ms CPU to 5.3-6.2 ms without reducing visual quality.
Release build succeeds with zero warnings and all 6,300 tests pass with five intentional skips. Three independent retail, architecture, and adversarial reviews are clean; the post-review connected route remains pending because local ACE is offline.

Three review finds, all in the runtime-toggle path or edge math (the
steady-state path was confirmed correct):
1. GPU stale-slot across toggle-off/on: the disabled branch now
Disposes the GpuFrameTimer (and nulls it) instead of Stop()-ing and
keeping it — a kept instance would poll slots left pending from
BEFORE the pause on re-enable and report temporally stale GPU
samples. The re-enable branch's existing null guard rebuilds the
ring fresh. Dispose is safe there: the branch runs at the top of
OnRender with the GL context current.
2. Stale stage accumulation across mid-stage toggle-off: a StageScope
disposed after the flag flips still calls EndStage, leaving a
partial delta in _stageAccumTicks. The re-baseline branch now
Array.Clear()s it alongside the GC re-baselining.
3. FrameStatsBuffer.Max() seeded with 0, clamping all-negative windows
(the alloc channel can go negative if the boundary ever crosses
threads) and disagreeing with Percentile(). Now seeds from the
first live sample after the empty check (slots [0.._count) are
always the live window regardless of ring wraparound); empty still
returns 0 to match Percentile. TDD: Max_AllNegative_ReturnsTrueMax
failed (returned 0) before the fix, passes after.

Permanent frame profiler: FrameBoundary() at the top of OnRender measures
CPU frame time (swap-to-swap delta), brackets the frame in a GpuFrameTimer
TimeElapsed query (self-disabled under ACDREAM_WB_DIAG=1), and samples
per-frame allocated bytes + GC collection deltas. BeginStage(FrameStage)
scopes attribute CPU time to Update/Upload/ImGui. Emits one [frame-prof]
report line every ~5s while RenderingDiagnostics.FrameProfEnabled is on;
zero-cost stage scopes when off. Report formatting is a pure static
method, unit-tested for invariant-culture formatting and the gpu=off
fallback text.
