Captures Phase M (Network Stack Conformance) as a fully-formed phase
ready to be picked up later. Three deliverables:
1. Design spec at docs/superpowers/specs/2026-05-10-phase-m-network-stack-design.md
(~700 lines, 8 sections):
- Bar C completeness target ("wireable on demand"): every wire opcode
a 2013 EoR retail client receives or sends gets a parser/builder +
golden-vector test + typed event in the new layered stack.
- Three-layer architecture: INetTransport / IReliableSession /
IGameProtocol, with WorldSession as a thin behavior consumer.
Concrete C# interface signatures, sub-component decomposition.
- Worktree-branch big-bang migration on claude/phase-m-network-stack;
weekly rebase cadence; single --no-ff merge ships the phase.
- Per-sub-phase entry/exit gates, conformance test plan (golden vectors
+ live capture replay + live ACE smoke), 10-row risk register, scope-
cut order if calendar compresses.
- Cost: 256 hours / ~6.4 weeks single-developer; 4-6 weeks calendar
with subagent parallelization on M.1 + M.6.
2. Opcode coverage matrix at docs/research/2026-05-10-phase-m-opcode-matrix.md
(~284 rows across 5 sections):
- Section 1: 22 transport flags (14 implemented).
- Section 2: 12 optional-header fields (10 partial).
- Section 3: 51 top-level GameMessages (21 implemented).
- Section 4: 103 GameEvent sub-opcodes inside 0xF7B0 (27 parsed,
26 wired).
- Section 5: 96 GameAction sub-opcodes inside 0xF7B1 (24 built,
8 with live callers).
- Roll-up: ~34% complete by raw opcode count. Biggest single
unblocking step is wiring the 16 dead builders in section 5
(Phase B.4 surface — Use / UseWithTarget / Allegiance / Inventory
/ Social / Cast / Appraise).
- Sources cited per row: holtburger (629695a), ACE, named retail
decomp, acdream current state.
- Produced by 4 parallel research agents (one per class). Spot-check
pass owed before M.1 closes.
3. Roadmap update: Phase M section trimmed to summary + status + pointer
to the spec; the previously-tracked M.0 Tier 1 quick-wins are folded
into M.3 / M.4 / M.6 per the spec; M.1 retained as the matrix
construction sub-lane with status note.
Why this shape: the user goal is a complete, layered, testable network
stack that can be wired in as gameplay phases need it — independent of
whether each opcode is yet hooked to game state. The matrix is the
source of truth for "done"; the spec is the architecture the matrix
implements against; the roadmap is the index that points at both.
Decisions captured during the design discussion (in case they need
revisiting):
- Bar C ("wireable on demand") chosen over Bar A (holtburger parity)
or Bar B (named-retail completeness).
- Three layers (INetTransport / IReliableSession / IGameProtocol)
chosen over holtburger's two-layer split.
- Big-bang on a feature branch (worktree) chosen over strangler
pattern; preserves live-ACE testing on main throughout the phase.

Holtburger reference fast-forwarded from 88b19bd to 629695a (+237 commits).
Four parallel research agents produced a parity-first-pass between
holtburger's network stack and acdream's src/AcDream.Core.Net/.
Why captured now: study surfaced six small, high-confidence "Tier 1" fixes
that can ship before the bigger M.1-M.8 layer extraction. Most likely fix
for the longstanding "remote retail observer sees us not perfect" bug
(MoveToState wire-format mismatches). Two transport gaps (no EchoResponse
reply, eager port-switch) match recent holtburger fixes (403bc98, 99974cc).
One latent bug worth a 5-min check (ISAAC search-mode for out-of-order
ENCRYPTED_CHECKSUM packets).
Captured as Phase M.0 in the roadmap so the work survives the session and
can be picked up later. Existing M.1-M.8 lift unchanged; M.1 marked as
partially started since the research note is the parity-map deliverable
in draft form.

After the post-A.5 lifestone (#52) + JobKind plumbing (#54) work shipped,
only Priority 3 (Tier 1 entity-classification cache retry, ISSUE #53)
remains. This handoff captures the audit insights gathered during the
#52 investigation that the original post-A.5 handoff didn't have:
- MeshRef is a `readonly record struct` — its fields can NOT be mutated
in place. The actual per-frame mutation for animated entities is the
entire MeshRefs LIST replacement at GameWindow.cs:7474-7553. This
reframes the cache design.
- _animatedEntities dict at GameWindow.cs:160 is the source of truth
for which entities go through the per-frame rebuild path.
- Static entity = entity.Id NOT in _animatedEntities. Its MeshRefs is
the same instance from spawn until rare events (ObjDesc / palette
swap / part hide / scale apply).
- Recommended cache approach: static-only with explicit invalidation
hooks on the network/spawn-time write sites enumerated in the doc.
Doc covers: where main is, what shipped this session, why the first
Tier 1 attempt failed, the pre-started audit, cache design options,
acceptance criteria, files to read, workflow for the next session, and
things-to-NOT-do.

Bug A's fix (commit `9217fd9`) patched at the worker output by stripping
entities from far-tier `LoadedLandblock`s after the full `LoadNear` path
ran. The worker still wasted CPU on `LandBlockInfo` reads + entity
hydration + `SceneryGenerator` math + interior-cell walks for ~544
far-tier LBs at radius=12, just to throw the work away.
This commit plumbs `LandblockStreamJobKind` through to the factory so the
worker can branch at the source:
- `LandblockStreamer.cs`: replace the `Func<uint, LoadedLandblock?>`
factory with `Func<uint, LandblockStreamJobKind, LoadedLandblock?>` as
the primary ctor signature. Add a back-compat overload that wraps the
old single-arg signature (`(id, _) => loadLandblock(id)`) so existing
test code keeps compiling without modification — the 5 ctor sites in
`LandblockStreamerTests.cs` now resolve to the overload. `HandleJob`
passes `load.Kind` to the factory; the post-load entity-strip is
retained as a `Debug.Assert` + Release safety net.
- `GameWindow.cs`: `BuildLandblockForStreaming(uint, JobKind)` branches
on `kind == LoadFar` at the top — reads only the `LandBlock` heightmap
dat and returns a `LoadedLandblock` with `Array.Empty<WorldEntity>()`.
Skips `LandblockLoader.Load` (which reads `LandBlockInfo`),
`BuildSceneryEntitiesForStreaming`, and `BuildInteriorEntitiesForStreaming`
entirely. Near-tier path is unchanged. Both call sites updated to pass
the kind through the lambda: `(id, kind) => BuildLandblockForStreaming(id, kind)`.
Tests: 1688/1696 (8 pre-existing physics/input failures unchanged).
Streaming-targeted filter (30 tests covering LandblockStreamer +
StreamingController + StreamingRegion) all green via the back-compat
overload — no test code needed updating.
Per-LB worker cost on far-tier: was ~tens of ms (full hydration,
including LandBlockInfo + scenery generation + interior cells); now a
single `LandBlock` dat read (~sub-ms).

Three root causes regressed the Holtburg lifestone since the WB rendering
migration (Phase N.5 retirement amendment, commit dcae2b6, 2026-05-08).
All confirmed via temporary [LIFESTONE-DIAG] instrumentation and visually
verified by the user through the +Acdream test character.
1. **Alpha-test discard** in mesh_modern.frag transparent pass killed
high-α pixels of dat-flagged transparent surfaces. Native AC
transparent surfaces routinely include effectively-opaque pixels —
e.g. the lifestone crystal core (surface 0x080011DE) — that compose
correctly under (SrcAlpha, 1-SrcAlpha) blending. The original N.5
§2 rationale ("high-α belongs in opaque pass") doesn't hold for
surfaces flagged transparent at the dat level: those pixels can't
reach the opaque pass at all. Fix: remove `α >= 0.95 discard` from
the transparent pass, keep `α < 0.05 discard` as a fragment-cost
optimization (skip totally-empty pixels).
2. **Cull state** for the transparent pass was unset by
WbDrawDispatcher after the N.5 retirement amendment deleted
StaticMeshRenderer.cs (which had the Phase 9.2 setup at commit
6f1971a, 2026-04-11). Closed-shell translucents — lifestone crystal,
glow gems — need GL_CULL_FACE + GL_BACK + GL_CCW in the transparent
pass; otherwise back faces composite over front faces in iteration
order under DepthMask(false). Fix: re-establish Phase 9.2's exact
GL state setup at the top of Phase 8.
3. **uDrawIDOffset uniform** was missing from mesh_modern.vert.
gl_DrawIDARB resets to 0 at the start of each
glMultiDrawElementsIndirect call, so the transparent pass — which
begins later in the indirect buffer — was fetching
Batches[0..transparentCount) instead of its actual section at
Batches[opaqueCount..end). The lifestone crystal ended up reading
the FIRST OPAQUE batch's TextureHandle every frame; as the camera
moved and the front-to-back opaque sort reordered which group
landed at BatchData[0], the crystal's apparent texture flickered to
whatever sat first — typically the player character's body parts.
Fix: add `uniform int uDrawIDOffset` to the vertex shader, change
Batches[gl_DrawIDARB] → Batches[uDrawIDOffset + gl_DrawIDARB], and
set the uniform per-pass in WbDrawDispatcher (0 for opaque,
_opaqueDrawCount for transparent). Mirrors WorldBuilder's
BaseObjectRenderManager.cs line 845.
Tests: 1688/1696 passing (8 pre-existing physics/input failures
unchanged). N.5b conformance sentinel 94/94 clean.
Visual: Holtburg lifestone now renders with the spinning blue crystal
correctly composed over the pedestal. Other transparent content (glass,
particle effects, NPC clothing) is unaffected — the same uniform fix
applies globally and is correct for all transparent draws.

Captures the three deferred items from A.5 ship:
- ISSUE #52: lifestone visual missing (1-3 hours, fast win)
- ISSUE #54: JobKind plumbing through BuildLandblockForStreaming
(~30 min - 1 hour, worker-thread efficiency cleanup)
- ISSUE #53: Tier 1 entity-classification cache retry (~5-7 days,
biggest perf win remaining; needs animation-mutation audit before
designing to avoid the freeze-pose bug from the first attempt)
Doc covers: A.5 final state + 3 high-value gotchas, files to read,
per-priority detail with effort estimates and acceptance criteria,
what NOT to do, the first-30-minute workflow, and the full A.5
commit chain for reference.
Phase is sized ~1 week if all three priorities land. The audit
step on Tier 1 is the highest-leverage investment.
Tier 2 + Tier 3 (static/dynamic split + GPU compute culling) are
explicitly out-of-scope for this phase — separate multi-week phases
per docs/plans/2026-05-10-perf-tiers-2-3-roadmap.md.

Closes ISSUES.md #13. PlayerDescriptionParser now walks the full
trailer (Options1 / Shortcuts / HotbarSpells / DesiredComps /
SpellbookFilters / Options2 / GameplayOptions blob / Inventory /
Equipped) ported from holtburger events.rs:503-625 +
shortcuts.rs:13-34. The trickiest piece — gameplay_options — uses a
4-byte-aligned forward heuristic (TryHeuristicInventoryStart)
mirroring holtburger's find_inventory_start_after_gameplay_options.
Trailer walk wrapped in its own inner try/catch so a malformed
trailer cannot destroy upstream attribute/skill/spell/enchantment
data; new Parsed.TrailerTruncated flag distinguishes clean parse
from graceful-degradation parse, with diagnostic log under
ACDREAM_DUMP_VITALS=1.
GameEventWiring registers parsed Inventory + Equipped into
ItemRepository at login (acceptance criterion: ItemRepository.Count
> 0 after login, exercised by GameEventWiringTests). 20 PD parser
tests + 1 wiring acceptance test; 282/282 AcDream.Core.Net.Tests
pass.
Plan: docs/superpowers/plans/2026-05-10-issue-13-pd-trailer.md.
Roadmap update: F.5a (visible-at-login dev panels) added as the
first deliverable that actually consumes the new trailer data —
ImGui dev panels under ACDREAM_DEVTOOLS=1 binding to
AcDream.UI.Abstractions ViewModels.
13 task commits + 1 review-followup + 1 nit-fix + 1 roadmap = 16
commits on the branch.
Sub-phase under existing F.5 (Core panels) capturing the immediate
follow-up to ISSUES.md #13: now that PlayerDescriptionParser surfaces
the full trailer (Inventory / Equipped / Shortcuts / HotbarSpells /
DesiredComps / Options1+2 / SpellbookFilters) and GameEventWiring
populates ItemRepository at login, F.5a wires that data into minimal
ImGui dev panels under ACDREAM_DEVTOOLS=1 so it's observable in-game.
Establishes the binding pattern (AcDream.UI.Abstractions ViewModels →
ImGui renderer) that the eventual D.2b retail-skinned F.5 panels
reuse. Spec to brainstorm before code.
Per docs/plans/2026-05-10-perf-tiers-2-3-roadmap.md Tier 1: cache the
per-(entity, meshRef, batch) classification (TextureCache lookup,
GroupKey hash, _groups dict insert) so the per-frame Draw inner loop
becomes "look up cache → walk assignments → append matrix to group's
Matrices list."
For static entities (~95% of world: trees, rocks, buildings, scenery),
the answer never changes between frames. Cache once at first visit;
reuse permanently. Per-frame work for static drops from 4 expensive
operations per (meshRef, batch) to 1 list-append.
Estimated entity dispatcher: 3.5ms → ~1-1.5ms median at radius=12.
Should land inside the 2.0ms spec budget.
Implementation:
- New EntityClassificationCache class (per-meshRef list of cached
(group ref, baked-PartTransform) tuples) keyed by entity.Id.
- ClassifyEntity does the one-time work; result populates _groups and
the cache.
- Draw inner loop: cache lookup → for each assignment, model =
PartTransform × entityWorld; group.Matrices.Add(model).
- Cache miss when ClassifyEntity finds NO mesh loaded yet (Vao == 0)
→ don't store; retry next frame. Avoids cache thrash during the
streaming-in window.
- Public InvalidateEntity(uint id) + ClearEntityCache() for explicit
invalidation hooks. Wiring (palette swap on ObjDescEvent, MeshRefs
hot-swap) is post-A.5 follow-up — for now, cache-stale entities
show their pre-swap appearance until next respawn.
Tier 2 (static/dynamic split with persistent groups) and Tier 3 (GPU
compute culling) tracked in the roadmap doc.

After PlayerDescription is dispatched, the Inventory and Equipped lists
produced by the parser are now fed into ItemRepository via AddOrUpdate +
MoveItem so inventory/paperdoll panels see items after login.
Acceptance test PlayerDescription_RegistersInventoryEntries_InItemRepository
confirms ItemCount goes 0→2 for a synthetic PD with two inventory entries.
282 Net.Tests pass.

Captured 2026-05-10 during Phase A.5 polish discussion. User asked why
the 9070 XT @ 1440p doesn't hit Unreal-level FPS for an old game like
AC. Answer: architectural — we rebuild the entire draw plan from
scratch every frame instead of caching pre-baked static-world data.
Tier 1 (entity-classification cache) lands as A.5 polish (separate
commit). Tiers 2 + 3 documented here for future scheduling:
- Tier 2 — Static/dynamic split with persistent groups
~2-week phase. Static entities (~95% of world) get permanent GPU-
resident matrix slots, populated at spawn, dirty-tracked for delta
upload. Per-frame CPU cost for static = LB-cull + dirty-flag check
only. Estimated entity dispatcher: 3.5ms → 0.5-1ms median.
400-600 FPS at standstill, radius=12.
- Tier 3 — GPU-side culling (compute pre-pass)
~1-month phase. Per-instance frustum cull moves to GPU compute
shader. Compute writes draw-indirect buffer; rasterizer reads it.
Estimated CPU dispatcher: ~0.05ms (essentially free).
600-1000+ FPS at standstill, radius=12.
Doc captures effort estimates, sub-decisions, risks, mitigations, and
scheduling triggers for each tier. Also notes the architectural
ceiling (~800-1500 FPS for a C# + GL client; reaching native engine
performance requires becoming a different engine).

T17's WalkEntities helper allocated a fresh List<(WorldEntity, int)>
per frame to hold the (entity, meshRefIndex) pairs that pass visibility
filters. At ~10K entities × ~3 mesh refs = ~30K tuples × 16 bytes =
~480 KB / frame of GC pressure on the render thread. The implementer's
self-review flagged this as a future N.6 optimization; the post-T26
diagnostic showed it materially contributing to the perf regression
(though Bug A — far-tier entity load — was the dominant factor).
Refactor: split WalkEntities into two overloads.
- WalkEntities(...) — test-friendly, allocates a fresh ToDraw list per
call. Tests keep using this signature unchanged.
- WalkEntitiesInto(..., scratch, ref result) — no-alloc, clears + populates
a caller-provided scratch list. Draw uses this with a per-dispatcher
_walkScratch field reused across frames.
Test count unchanged (40 streaming + 8 bucketing tests still pass).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Phase A.5's two-tier streaming spec promised that far-tier landblocks
ship terrain ONLY — no entities, no scenery, no interior cells. T13/T16
wired the controller side (RecenterTo emits ToLoadFar/ToLoadNear/ToPromote;
controller passes JobKind to the worker), but the worker's HandleJob
never branched on Kind: every load called BuildLandblockForStreaming
which runs the full hydration + scenery generation + interior cell path.
Result: at default radii (N₁=4 / N₂=12), 540 far-tier LBs each loaded
their full entity layer (~132 entities/LB → ~71K entities total) into
GpuWorldState. The dispatcher then walked all ~54K entities per frame
(post-frustum-cull), driving the entity dispatcher cpu_us from ~3.6ms
median (T24 baseline) to ~18-21ms (post-T22.5 horizon-test). User-
observed: 40 FPS / 25ms frame time at horizon-safe settings; system
crash at full High preset.
Minimum-diff fix: in LandblockStreamer.HandleJob, after
_loadLandblock returns, strip Entities to empty for LoadFar before
posting Loaded. Worker still does wasted hydration CPU (off the render
thread, harmless). Render-side dispatcher walk drops from ~54K to ~10K
entities/frame.
Math: post-fix entity dispatcher should drop to ~3-4ms median at N₁=4 /
N₂=12 (matches T24's 3.6ms at radius=5 single-tier, since N₁=4 has 33%
fewer near entities than N₁=5).
Future optimization (N.6 / A.6): plumb JobKind through
BuildLandblockForStreaming so the worker also skips the wasted CPU.
Out of A.5 scope.
Bug B (T17 WalkEntities allocation) is a smaller perf hit — defer if
post-Bug-A FPS is acceptable.

GameWindow.OnLoad resolves QualitySettings.From(_persistedDisplay.Quality)
+ WithEnvOverrides() immediately after LoadAndApplyPersistedSettings, stores
result in _resolvedQuality field. All six quality dimensions applied:
- NearRadius / FarRadius: replace old T16 env-var-only block; preset drives
the radii, legacy ACDREAM_STREAM_RADIUS override still honoured.
- MsaaSamples: WindowOptions.Samples reads from startup quality resolution
in Run() (pre-window-create read from SettingsStore). MSAA cannot change
at runtime; ReapplyQualityPreset logs a restart-required warning if the
new preset would change it.
- AnisotropicLevel: TerrainAtlas.SetAnisotropic() called after Build() and
again in ReapplyQualityPreset. Temporarily removes bindless residency
before the GL TexParameter call, re-makes resident after.
- AlphaToCoverage: WbDrawDispatcher.AlphaToCoverage property gates the
glEnable/glDisable(SampleAlphaToCoverage) pair around the opaque pass.
- MaxCompletionsPerFrame: set on StreamingController after construction
and after each mid-session restart.
ReapplyQualityPreset(QualityPreset) method handles mid-session changes
(Settings panel Quality dropdown Save): rebuilds streamer + controller for
radius changes, toggles A2C and aniso immediately, logs MSAA restart caveat.
onSaveDisplay callback updated to call ReapplyQualityPreset when Quality
field changes.
TerrainModernRenderer.Atlas property added to expose the atlas for
mid-session aniso updates.
991 tests passing, 8 pre-existing failures unchanged.

Add QualityPreset enum + QualitySettings readonly record struct with
From(preset) table and WithEnvOverrides() env-var override layer.
Four presets (Low/Medium/High/Ultra) drive NearRadius, FarRadius,
MsaaSamples, AnisotropicLevel, AlphaToCoverage, MaxCompletionsPerFrame.
Env vars (ACDREAM_NEAR_RADIUS, ACDREAM_FAR_RADIUS, ACDREAM_MSAA_SAMPLES,
ACDREAM_ANISOTROPIC, ACDREAM_A2C, ACDREAM_MAX_COMPLETIONS_PER_FRAME)
override individual preset fields for dev spot-testing.
DisplaySettings gains a Quality: QualityPreset field (default High);
SettingsStore persists/loads it under display."quality" as an enum
name string with Enum.TryParse fallback. 12 new QualityPresetTests
cover the preset table (radii, msaa, aniso, a2c, completions) and all
six env-var override paths. 415 UI.Abstractions tests passing.
Wiring into GameWindow / WbDrawDispatcher / TerrainAtlas follows in
commit 2 of this task.

Per Phase A.5 spec §2 acceptance criterion 6: entity dispatcher median
≤ 2.0ms; terrain dispatcher median ≤ 1.0ms at standstill. When the
median exceeds the budget, prefix the DIAG line with " BUDGET_OVER" so
the regression is grep-friendly during perf testing.

Per Phase A.5 spec §4.8: fog ramp is tuned to mask the N₁ scenery
boundary. FogStart = N₁ × 192m × 0.7 ≈ 538m at default radii (4/12).
FogEnd = N₂ × 192m × 0.95 ≈ 2188m. Multipliers exposed as env vars for
fast iteration during visual gate.
Override is injected into the UBO after SceneLightingUbo.Build() so fog
color, lightning flash and mode still come from the sky keyframe. Adds
ParseEnvFloat helper (InvariantCulture) for float env-var parsing.

Code-quality review followup on Task 2 (becbde6) — addresses I1 (the
forward-looking concern that Tasks 3-9's inner-catch will leave partial
lists visible to callers with no signal) and M1 (silent inner catch).
Changes:
- Parsed gains a trailing `bool TrailerTruncated` field. Both
construction sites pass `false` by default; the trailer try/catch
flips a local `trailerTruncated` to `true` on FormatException and
feeds it into the final return.
- Inner catch logs `pos`/`payload.Length`/exception message under
ACDREAM_DUMP_VITALS=1, mirroring the outer catch's diagnostic
pattern.
- Task 2 test strengthened to assert defaults on Options2 /
SpellbookFilters / HotbarSpells / DesiredComps / GameplayOptions /
Equipped + TrailerTruncated=false (M2 followup — gives Tasks 3-9
a regression guard if they consume into the wrong field).
- New test `TryParse_TrailerAbsent_LessThan8BytesAfterEnchantments_*`
documents the contract that <8 bytes after enchantments means the
trailer is absent (not truncated): TrailerTruncated stays false,
upstream attribute data survives.
- Plan updated in lockstep so Tasks 3-11 implementers see the
`trailerTruncated` local and the new return-arg position.
271/271 AcDream.Core.Net.Tests pass.
Per Phase A.5 spec §4.9.2: ClipMap foliage uses binary alpha-cutoff.
At N₂=12 horizon distance the pixel-stepped silhouettes are visible.
A2C with MSAA 4x produces smooth retail-faithful tree edges.
GL context now requests Samples=4. WbDrawDispatcher's opaque pass
toggles GL_SAMPLE_ALPHA_TO_COVERAGE on/off around the multi-draw
indirect call. mesh_modern.frag's opaque pass now discards only
truly-empty (α<0.05) so the GPU derives sample mask from coverage;
transparent pass boundary logic is unchanged.
MSAA audit: no custom FBOs found — all rendering uses default
framebuffer. Sky/particles/ImGui are all MSAA-compatible.

Per Phase A.5 spec §4.9.1: at N₂=12 distant terrain LBs occupy a few

Per Phase A.5 spec §4.6 Change #2: WalkEntities's per-entity AABB
frustum cull was recomputing Position±5 per frame per entity. With
~10.7K entities (N1=4) at 240 FPS that is ~2.5M wasted Vector3
ops/sec.
Read the AABB from the WorldEntity cache (T8 schema) instead.
RefreshAabb runs lazily on AabbDirty=true. Populate at register time:
- LandblockLoader.BuildEntitiesFromInfo: RefreshAabb after each new
WorldEntity construction (stabs + buildings). Refactored from
inline object-initializer to named variable to enable the call.
- EntitySpawnAdapter.OnCreate: RefreshAabb after entity state init
(position/rotation already set via the WorldEntity passed in).
Dynamic entities (NPCs, players) move every frame via direct
Position writes in GameWindow.cs. Migrated all three per-frame
write sites to SetPosition() (T8 mutator) so AabbDirty propagates:
- line 5942: player entity render position update
- line 6951: remote animated entity interpolated path
- line 7279: remote animated entity landing/movement path
The lazy RefreshAabb in WalkEntities catches up on the next frame
after any SetPosition call — render thread only, no races.
Build green, 986 passed / 8 pre-existing failures unchanged.

First step of the PD trailer walk. Wraps trailer reads in their own
try/catch so a malformed trailer does not null out the upstream
attribute/skill/spell/enchantment data we already extracted.

Per Phase A.5 spec §4.6 Change #1: when an LB is invisible AND
animatedEntityIds is non-empty, the inner loop walked every entity
in the LB just to find the few animated ones. At ~10.7K entities
(N1=4) that is wasted iteration cost per frame.
Extracted a pure-CPU internal static WalkEntities helper. When LB
is invisible: iterate animatedEntityIds directly and look each up
in a per-LB AnimatedById dictionary (typically <50 animated vs
~10K total). When LB is visible: walk all entities as before.
GpuWorldState.LandblockEntries now yields an AnimatedById map as a
5th tuple field alongside the AABB tuple. Dictionary is built on
each yield (cheap — ~132 entities/LB max). A caching layer is out
of A.5 scope.
WbDrawDispatcher.Draw signature updated to consume the 5-tuple.
GameWindow.cs call site passes _worldState.LandblockEntries which
now yields the 5-tuple — no change needed there.
8 new tests in WbDrawDispatcherBucketingTests cover T17 Change #1
(invisible LB / animated set / neverCull / null frustum) and
T18 Change #2 guard tests (cached AABB / dirty flag / animated bypass).

Code review nit-fix on top of d3b58c9 — addresses two issues from the
quality review of Task 1:
I1 (Important): the record struct `Shortcut` was a homograph with the
flag member `CharacterOptionDataFlag.Shortcut`. Both names live inside
`PlayerDescriptionParser`'s scope. Rename to `ShortcutEntry` aligns
with `InventoryEntry`/`EquippedEntry` and removes the trap before
Task 3's walker references both names in the same method body.
M2 (Minor): `EquippedEntry` had no holtburger source citation; added
one referencing events.rs:180-190. Also expanded `InventoryEntry`'s
comment with the strict reader's validation reference.
Plan doc updated in lockstep so Task 3+ implementers see the new name.
8/8 PlayerDescriptionParser tests still pass.
Commit 19b4465's new ToPromote test pre-loaded an LB with a non-
canonical id (low 16 bits 0x0FFF instead of 0xFFFF). The new
canonicalization in AddEntitiesToExistingLandblock then key-missed and
parked the entity in the pending bucket instead of merging — assertion
failed.
Use canonical id 0x3232FFFFu directly. The test now exercises the
intended hot-path (merge into existing LB), not the cold pending-bucket
fallback (which is exercised by GpuWorldStateTwoTierTests).

Commit 19b4465 broke build by omitting required-member init for
SourceGfxObjOrSetupId/Position/Rotation in the new ToDemote/ToPromote
tests. WorldEntity has [required] on those fields (CS9035). The lone
test run that reported 38 passing used pre-existing binaries built
before this break.
Added all three required initializers (zero / Identity defaults — these
test the routing path; entity content doesn't matter).

Code review on T13-T16 bundle (commits fb10c3f/aff35d2/b8d80fe/c4fd373/31d312a)
flagged 3 Important + 2 test-coverage gaps. Apply all 5:
Important #1: GpuWorldState.AddEntitiesToExistingLandblock didn't
canonicalize landblockId. Streaming callers always pass canonical
0xAAAA0xFFFF ids, but the public API silently key-missed for callers
that mirror AppendLiveEntity's cell-resolved-id pattern. Both new
methods now canonicalize the id on entry.
Important #2: RemoveEntitiesFromLandblock asymmetry with RemoveLandblock
re: persistent-entity rescue. Documented as intentional — demote-tier
entities are atlas-tier only (procedural scenery, dat-static stabs/
buildings; never ServerGuid != 0); the local player and live server
spawns live in their LB via RelocateEntity per frame and aren't
affected by atlas-layer demote.
Important #3: StreamingController.NearRadius / FarRadius were { get; set; }
but mutating them after the first Tick is a no-op (StreamingRegion
snapshots the values). Switched to { get; } only with XML doc warning.
Test gap #1: ToDemote routing through Tick — added test that walks
the player past hysteresis and asserts entities drop while terrain
stays.
Test gap #2: Promoted result routing through Tick — added test that
enqueues a Promoted and asserts AddEntitiesToExistingLandblock fires.
Deferred Minor: dead _streamingRadius write + style consistency on
fully-qualified IReadOnlyList — non-load-bearing, can roll into a later
cleanup.

No behavior change yet — adds CharacterOptionDataFlag, Shortcut/Inventory/
EquippedEntry records, and extends Parsed with trailer fields filled with
empty defaults. Sets up the per-section TDD walk in subsequent commits.
Cosmetic follow-up flagged by spec compliance review on T13-T16 bundle
(commits fb10c3f / aff35d2 / b8d80fe / c4fd373). The debug overlay's
getStreamingRadius callback was reading _streamingRadius — the legacy
single-tier field that's only updated by ACDREAM_STREAM_RADIUS. Operators
using the new ACDREAM_NEAR_RADIUS / ACDREAM_FAR_RADIUS env vars would
see the overlay frozen at the default 2.
Switch to _nearRadius. The overlay still shows a single number (matching
its label "Streaming radius"); operators who want both tier numbers can
read the launch log.

GameWindow now constructs StreamingController with nearRadius / farRadius
defaults of 4 / 12 (per spec acceptance criterion). Env vars:
- ACDREAM_NEAR_RADIUS (default 4)
- ACDREAM_FAR_RADIUS (default 12)
- ACDREAM_STREAM_RADIUS (legacy; if set, treats as nearRadius and
bumps farRadius to max(stream, default))
Fields _nearRadius / _farRadius added alongside legacy _streamingRadius
(kept so the debug overlay's getStreamingRadius callback stays valid).
ApplyLoadedTerrainLocked routes to TerrainModernRenderer.AddLandblockWithMesh
(T15) instead of AddLandblock directly, making the two-tier entry point
the canonical call path.

Replaces the single-radius Tick with a two-tier model that consumes
StreamingRegion's TwoTierDiff (5-list) and routes to the appropriate
JobKind:
- ToLoadFar -> _enqueueLoad(id, LoadFar)
- ToLoadNear -> _enqueueLoad(id, LoadNear)
- ToPromote -> _enqueueLoad(id, PromoteToNear)
- ToDemote -> _state.RemoveEntitiesFromLandblock(id) on render thread
- ToUnload -> _enqueueUnload(id)
Drain switch handles Loaded (terrain + entity layer), Promoted (entity
layer only -- terrain already loaded), Unloaded, Failed, WorkerCrashed.
Constructor signature: nearRadius/farRadius separate ints. Old single-
radius ctor removed; existing single-radius tests updated to pass
nearRadius=farRadius for backward-compat coverage.
GameWindow's enqueueLoad lambda updated from (id =>...) to (id, kind) =>
to match new Action<uint, LandblockStreamJobKind> signature; radius: arg
renamed to nearRadius:/farRadius: (both set to _streamingRadius until T16
wires the full two-tier env-var parsing).
