docs(perf): audit errata + plan governance/contract amendments (2026-07-24 review)
Adversarial review of the 2026-07-24 runtime audit + modern runtime plan
(43-agent verification at e627d9a4). Audit: append errata section 13 --
the capture ran with ACDREAM_UNCAPPED_RENDER=1 + ACDREAM_DUMP_MOVE_TRUTH=1
(not "normal capped presentation"; the 32 FPS ceiling was the RDP display
path); the 203.6 MiB single-frame figure is frame-thread-only and cannot
include worker-side MeshExtractor decode (it is main-thread publication/
retirement); GiB conversions, committed-peak, 65% LOH fragmentation,
exception-count provenance, GC-counter semantics, and cache-undersizing
corrections. Original sections left untouched per historical-record rules.
Plan: new section 0 governance interlocks (Slices F/G resume the deferred
2026-07-05 MP3/ECS decision -> explicit user gate; side-track session
discipline; freeze-exception scope for H-network/J; evidence-base
corrections; baseline prerequisite blocking Slice C). Slice amendments:
A (per-frame history, process-wide alloc, contention stacks, cache
counters, screenshot-diff pulled forward, reference config, exit criteria),
C (Portal-dat-wins precedence contract, dual-dat + ObjDesc fixtures, cache
identity rule, exception-semantics cleanup), D (unify/retune existing
eviction rather than rebuild; ResidencyManager concurrency contract),
E (gate rescoped to what E owns; release-later != run-later; audio in the
immediate detach set; reveal stall behavior with the AP-115 cue; retail
teardown anchors), F (referee-first digest, journal coalescing bound,
IRenderScene home project, identity enforcement), G (provisional 300 FPS
target; retail dynamics viewcone-cull contract), H (split H-a/H-b/H-c with
the AP-85 lights pin and receive-side allocation scope), I (verbatim-float
bake rule + differential BSP sweep; floats after B), J (teardown protocol,
multi-plan track), K (wire-timing parity per TS-33, hours-scale soak).
Section 11 gate corrections (percentile populations, anti-gaming
process-wide row, provisional budgets, scoped third-visit rule, soak +
jitter rows, scheduled harness); section 12 adjudication protocol;
section 14 order list now includes Slice I and the user decision gate.

## 0. Governance and standing-decision interlocks (2026-07-24 review)
|
||||
|
||||
Added by the 2026-07-24 adversarial review. These interlocks are binding on
|
||||
every executor of this plan; the audit's correction record is
|
||||
[`../research/2026-07-24-runtime-performance-audit.md`](../research/2026-07-24-runtime-performance-audit.md)
|
||||
section 13.
|
||||
|
||||
1. **The ECS deferral stands until the user lifts it.** On 2026-07-05 the
|
||||
user deferred the ECS/MP3 render-world rewrite ("revisit ONLY if the user
|
||||
wants a higher raw FPS number and accepts the rewrite risk" —
|
||||
`claude-memory/project_mp_track_findings.md`), and the follow-up
|
||||
measurement note concluded MP3 was not warranted for town FPS. Slices A–E
|
||||
do not touch that deferral. **Slices F and G resume the deferred MP3
|
||||
work and MUST NOT start without explicit user approval recorded against
|
||||
this section**, taken on the post-Slice-E corrected uncapped-local
|
||||
profile (does partition/submission cost still dominate?). Note the prior
|
||||
"GPU-bound at ~200 FPS" Sawato reading is itself invalidated by the
|
||||
`GpuFrameTimer` boundary artifact this plan's Slice A corrects — the
|
||||
question is genuinely open until re-measured.
|
||||
2. **Session discipline.** This plan executes in dedicated Track MP/LH
|
||||
side-track sessions only. The ACTIVE milestone's critical path wins every
|
||||
conflict; do not begin any slice inside a milestone session.
|
||||
3. **Freeze-exception scope.** The recorded 2026-07-05 Track MP exception
|
||||
covers streaming and WB rendering only. Slice H's network-I/O item and
|
||||
Slice J's gameplay-owner moves touch otherwise-frozen subsystems
|
||||
(network, chat, input) and each requires its own recorded user
|
||||
authorization before starting. (The 2026-07-24 receive-thread robustness
|
||||
fix was separately reviewed and user-approved as a bug fix, not a
|
||||
rework.)
|
||||
4. **Evidence-base corrections.** The §1 exception-traffic row previously
|
||||
cited "4,520 + 1,168" — figures with no derivation in the audit or its
|
||||
committed artifacts; the verifiable figures are the focused-trace 1,587
|
||||
(1,335 invalid DAT probes + 252 receive timeouts). And the audit's
|
||||
204 MiB single-frame allocation is a FRAME-THREAD measurement that cannot
|
||||
include worker-side mesh decode: **Slice E owns the frame-spike symptom;
|
||||
Slices B/C own the process-wide allocation rate and GC pressure.** Win
|
||||
attribution must respect that split.
|
||||
5. **Baseline prerequisite.** No behavior-changing slice (C onward) starts
|
||||
until the Slice A exit criteria in §10 are met: committed uncapped-local
|
||||
AND capped-local nine-stop baselines, a pinned dense-town uncapped
|
||||
baseline, and per-portal allocation/frame timelines, all captured with
|
||||
the corrected tooling and a committed reference-hardware definition.

|
||||
|
||||
- Per-frame history export (frame index, stage times, frame-thread alloc,
|
||||
gpu time) — landed post-review via `ACDREAM_FRAME_HISTORY`; route-wide
|
||||
p50/p95/p99 populations must come from this export. Until it is the gate
|
||||
population, every percentile gate reads "no 5-second window with p99 > X".
|
||||
- Process-wide allocation rate per scene (dotnet-counters) alongside the
|
||||
frame-thread profiler, plus a per-thread split recipe — the frame-thread
|
||||
gates alone are gameable by moving work to workers (§0.4).
|
||||
- One contention capture WITH STACKS on the route (the 4,614 contentions are
|
||||
unattributed; `_datLock` build-vs-hydration and
|
||||
`ObjectMeshManager._pendingRequests` are the leading candidates, not only
|
||||
the DAT typed-object lock).
|
||||
- Cache hit/miss/evict counters in the checkpoint JSON (landed post-review)
|
||||
so Slice B/C wins are attributable to cold-vs-warm portals.
|
||||
- LOH size + fragmentation (+POH) checkpoint fields (landed post-review; the
|
||||
audit's own JSON showed 65% LOH fragmentation, never analyzed).
|
||||
- Fixed-camera screenshot COMPARISON tooling (pulled forward from Slice G)
|
||||
with a defined match rule (per-channel tolerance + max differing-pixel
|
||||
fraction; pinned `/time`, pinned camera, particles pinned-seed or masked).
|
||||
Slice C's visual gate depends on it existing.
|
||||
- A committed reference-configuration block (CPU, GPU, driver, OS build,
|
||||
display path, resolution, refresh, VSync state, re-baseline rule) — the
|
||||
§11 phrase "reference local hardware" is undefined without it.

|
||||
|
||||
**Amendment (2026-07-24 review).** Binding contracts for this slice:
|
||||
|
||||
- **Precedence contract.** The LINQ being replaced is load-bearing content
|
||||
selection, not just allocation:
|
||||
`OrderByDescending(r => r.Database == _dats.Portal)` means
|
||||
**Portal-dat-wins** when an id resolves in more than one database. The
|
||||
typed non-allocating lookup must encode that precedence explicitly, and
|
||||
the equivalence fixtures must include at least one dual-dat id (an id
|
||||
shadowed by `client_highres.dat`) so a precedence regression fails the
|
||||
gate instead of silently changing pixels.
|
||||
- **Seam fixtures.** The DAT-equivalence suite must include ObjDesc-composed
|
||||
fixtures that straddle the bake/runtime split: a drudge, a robed player,
|
||||
and palette-dyed armor (baked base mesh + runtime appearance overlay).
|
||||
- **Cache identity rule.** Pak-backed default-palette pixels and
|
||||
runtime-composed palette-overlaid pixels for the same surface id are
|
||||
distinct cache identities and must never share a key.
|
||||
- **Exception semantics.** When the probe storm is removed, also narrow
|
||||
`ResolveActivation`'s bare `catch { return null; }` (and the sibling
|
||||
`SequencerFactory`, which today has NO catch at all): catch only the
|
||||
specific corrupt-data exception types, rethrow `OperationCanceledException`,
|
||||
log anything unexpected. Otherwise the "no exception storm" gate can pass
|
||||
while real activation failures stay invisible — the pattern CLAUDE.md's
|
||||
no-workarounds rule names explicitly.
|
||||
- **Baseline comparison validity.** "p99 materially improve" compares
|
||||
against the post-Slice-A uncapped-local baseline, not the capped-RDP
|
||||
2026-07-24 capture (whose steady p99 sits at the 31.2 ms display floor).
|
||||
Portal single-frame allocation is FPS-independent and may compare against
|
||||
either.

|

|
||||
**Amendment (2026-07-24 review).** Two corrections to this slice's scope:
|
||||
|
||||
- **Do not rebuild what exists.** Fence-gated, budgeted eviction already
|
||||
runs per frame in three of the four systems this slice names:
|
||||
`ObjectMeshManager` (1 GiB / 50-object LRU, reclaimed every frame),
|
||||
`CompositeTextureArrayCache` (128/64 MiB budgets, per-frame throttled GL
|
||||
deletion), and `GlobalMeshBuffer` (capacity shrink with hysteresis). The
|
||||
2026-07-24 route never pushed those ceilings, so its "bounded" residency
|
||||
was bounded-by-route, not policy-exercised. Slice D's job is to UNIFY
|
||||
accounting and observability over the existing physical caches, add a
|
||||
forced-pressure eviction test (deliberately exceed the ceilings), and
|
||||
retune the budgets for multi-session load — plus bring policy to the
|
||||
items that genuinely have none: deferred-alpha scratch arrays,
|
||||
`ObjectMeshManager._boundsCache`, and the audio/animation content caches
|
||||
(audio caches bounded post-review).
|
||||
- **Concurrency contract before code.** The `ResidencyManager` design in
|
||||
§5.3 lists states with no transitions. Before this slice starts, its plan
|
||||
must specify: a transition table including failure/cancellation/corrupt
|
||||
edges; which fields are single-thread-owned vs shared (policy decisions
|
||||
on the update thread, physical release render-thread-only, accounting via
|
||||
atomics or a single-writer journal); the rule that eviction never blocks
|
||||
the render thread and never runs under a lock the render thread takes;
|
||||
and that `ResidencyManager` never touches GL names (only the renderer
|
||||
resource owners row of §4 may).

**Amendment (2026-07-24 review).** Binding contracts for this slice:
|
||||
|
||||
- **Release-later never means run-later.** Retired-generation owners are
|
||||
tick-frozen and audio-silenced at the immediate detach edge even when
|
||||
their memory release is budgeted across later frames. Audio is added to
|
||||
the immediate set (or bounded at ≤1 frame): a looping emitter on a
|
||||
retired landblock is user-audible during portal transit, and audio
|
||||
appears in neither of §6.2's lists today. Retail teardown anchors for the
|
||||
slice plan: `CLandBlock::Destroy` 0x0052faa0, `destroy_static_objects`
|
||||
0x0052fa50, `CObjectMaint::DestroyObjects` 0x00508c30 (retail teardown is
|
||||
one synchronous transaction; deferral has retail precedent only via the
|
||||
`AddObjectToBeDestroyed` queue, whose drain is complete-when-run).
|
||||
- **Reveal stall behavior.** A reveal hold longer than retail's 5-second
|
||||
fade ceiling keeps the tunnel animating, surfaces the retail "In Portal
|
||||
Space - Please Wait" cue (AP-115), and emits a diagnostic — never a
|
||||
silent early reveal. The `IsUnhydratable` loud-failure escape stays.
|
||||
Retail anchor: `SmartBox::UseTime` 0x00455410 `blocking_for_cells`; the
|
||||
1/2/5 s fade thresholds are recorded in
|
||||
`claude-memory/project_portal_space.md`.
|
||||
- **All count constants convert.** `MaxCompletionsPerFrame` is not the only
|
||||
count-shaped budget: `MaxDrainIterations` (the ×64 outer drain ceiling)

and the priority-ring radius are part of the same redesign; and the

uncapped one-frame paths (`BeginFullWindowRetirement`,

`TryAdvanceOriginRecenterPreparation` — the ~600-landblock teleport

retire) are the primary offenders, not the 9-landblock eager ring.

- Deferred loads retained in `_deferredApply` during a burst are a

them under the CPU-bytes budget.

before it gates a mirror. During soak/dev runs the digest also runs

continuously through portal windows (every N frames), not only at the

nine checkpoints — checkpoint-only comparison is blind to drift that

self-corrects between stops, which peaks exactly when churn does.

no-block rule for the update thread.

types live in `AcDream.App` for Slices F–I. At Slice J the seam becomes

Runtime-emitted ordered entity events (incarnation + transform + flags,

renormalization, no quantization, no double round-trips); (b) traversal

|

**Amendment (2026-07-24 review).** Gate-table corrections and additions:
|
||||
|
||||
- **Percentile populations.** Until the Slice A per-frame history export is
|
||||
the population, every p99 row reads "no 5-second window with p99 > X" —
|
||||
the windowed profiler cannot produce route-wide percentiles.
|
||||
- **Anti-gaming complement.** New row: process-wide steady allocation rate
|
||||
per scene (dotnet-counters), alongside the frame-thread rows. The
|
||||
frame-thread gates alone reward moving garbage to workers, which is this
|
||||
plan's own remediation shape.
|
||||
- **Provisional budgets.** "≤ 4 MiB portal" and "≤ 4 KiB steady" are
|
||||
round-number initial budgets, not derived values; tighten from post-A/C
|
||||
evidence. "0 B/frame" means alloc p50 = 0 with every nonzero frame
|
||||
attributable to the profiler/report path (the instrument itself allocates
|
||||
its 5-second report on the frame thread).
|
||||
- **Third-visit growth ≤ 5%** is scoped per metric class: same-location
|
||||
tracked CPU/GPU residence measured against the location's own asset set
|
||||
(possible after Slice D accounting); entity/emitter/particle counts stay
|
||||
warnings on a live ACE world; absolute byte deltas reported alongside
|
||||
percentages. The audit's own data shows legitimate +31.7% Sawato
|
||||
tracked-GPU growth from route-wide cache warming — the unscoped gate
|
||||
false-fails on exactly that.
|
||||
- **New row — long-duration soak:** ≥ 60 minutes looping the route; managed
|
||||
heap, LOH size + fragmentation, tracked GPU, handles, and threads all
|
||||
plateau within stated bands. (The canonical route is 359 s; the #193
|
||||
leak class is invisible to it.)
|
||||
- **New row — frame-pacing jitter** (stddev / 99.9th) once the per-frame
|
||||
export exists.
|
||||
- **Scheduled harness.** Slice A or H tasks a scheduled local perf harness:
|
||||
run the committed route against the last committed baseline JSON with the
|
||||
soak script's relative-limit pattern applied cross-commit, failing
|
||||
loudly. Manual-and-unscheduled is not a regression net.
|

- "Reference local hardware" refers to the committed reference-configuration

block required by Slice A; gates against an undefined machine are

unfalsifiable.
