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)
Make scripted lifecycle checkpoints acknowledged post-diagnostics render barriers, capture the exact frame outcome beside canonical resource ownership, and harden the nine-stop route with ordered same-location cache and lifetime gates without weakening process residency thresholds.

Move the complete update/render construction graph into a typed Phase-8 owner, explicitly carry the content dependencies it consumes, and publish both roots through one exact lease. Extract lifecycle resource sampling and frame-owned late bindings so partial startup and shutdown withdraw the same generation without window callbacks.

Move the live-session reset and routing graph, combat and diagnostic command targets, and the sole gameplay input subscriber into Phase 7 before frame publication. Add exact retryable ownership for late bindings so partial startup cannot strand session or component teardown edges.

Move the accepted draw transaction and failure recovery behind typed frame-phase owners so GameWindow only supplies immutable frame input. Preserve retail draw order, make ImGui/bootstrap shutdown ownership explicit, and restore exact text-render GL state on failures.\n\nCo-authored-by: Codex <codex@openai.com>
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.

RenderingDiagnostics.FrameProfEnabled is the master toggle for the
upcoming permanent frame profiler (ACDREAM_FRAME_PROF=1, runtime
mirror via DebugVM.FrameProf). GpuFrameTimer wraps a depth-4 ring of
TimeElapsed queries for whole-frame GPU time, mirroring
WbDrawDispatcher's query idiom (including the #125 never-begun-slot
guard). Caller must not run this while ACDREAM_WB_DIAG=1 owns
TimeElapsed queries — GL forbids nested TimeElapsed queries.

Fixed-capacity ring buffer of long samples with nearest-rank percentile
and max over the current window. Pure, allocation-free after
construction. Foundation for the MP0 frame profiler
