Two retail divergences fixed from the 2026-05-16 faithfulness audit
(Commit A of the plan at docs/superpowers/plans/2026-05-16-retail-faithfulness-fixes.md).
1. Rotation rate ignored HoldKey.Run. Retail's CMotionInterp::
apply_run_to_command (decomp 0x00527be0 line 305098) multiplies
turn_speed by run_turn_factor (1.5, PDB-named symbol at 0x007c8914)
when input is TurnRight/TurnLeft under HoldKey.Run. Effective
running rotation is 50% faster (~135°/s vs walking ~90°/s).
Our keyboard A/D and ApplyAutoWalkOverlay used a fixed walking
rate.
New: RemoteMoveToDriver.TurnRateFor(running) helper. Keyboard
path passes input.Run; auto-walk overlay passes
_autoWalkInitiallyRunning. The walking-rate base
(BaseTurnRateRadPerSec = π/2) is unchanged; TurnRateRadPerSec
constant is preserved as the walking-rate alias for callers
that don't have run/walk state (NPC remotes).
2. IsUseableTarget gated on `useability & USEABLE_REMOTE (0x20)`,
which was stricter than retail. Per ItemUses::IsUseable
(acclient_2013_pseudo_c.txt:256455) cross-referenced with 4
call sites, retail's IsUseable() semantic is `_useability != 0`.
But visually retail's USEABLE_NO (1) entities don't approach
either, because ACE never broadcasts MovementType=6 for them.
Our client installs a speculative auto-walk BEFORE the server
responds, so we'd visibly approach + face signs before the
wire packet was rejected.
Pragmatic fix: block USEABLE_UNDEF (0) AND USEABLE_NO (1) in
IsUseableTarget — slightly stricter than retail's
IsUseable but matches retail's user-visible behaviour
("R on sign does nothing"). Documented in the doc-comment so
a future implementer knows the gap.
3. New IsPickupableTarget gate for F-key path — requires
USEABLE_REMOTE (0x20) bit. Null-useability fallback for
BF_CORPSE + small-item ItemTypes (preserves M1 ground-item
pickup flow when ACE seed DB doesn't publish useability).
4. R-key (UseCurrentSelection) upfront gate now ALWAYS uses
IsUseableTarget. R is conceptually "use" with smart-routing
to pickup as a downstream optimization. F-key (SendPickUp)
uses IsPickupableTarget directly.
5. Retail toast strings on block, centralised in new
src/AcDream.Core/Ui/RetailMessages.cs:
- "The X cannot be used" (data 0x007e2a70, sprintf 0x00588ea4)
fires on UseCurrentSelection / SendUse gate block.
- "The X can't be picked up!" (sprintf 0x00587353) fires on
SendPickUp non-pickupable block.
- "You cannot pick up creatures!" (data 0x007e22b4) fires on
SendPickUp creature block (was previously silent).
- Plus 4 inactive retail strings ready for future call sites:
CannotBeUsedWith (two-target Use), CannotBePickedUp (formal
pickup variant), CannotBeUsedWhileOnHook_HooksOff +
CannotBeUsedWhileOnHook_NotOwner (housing). All cite their
retail data addresses + runtime sprintf addresses.
6. ProbeUseabilityFallbackEnabled diagnostic (env var
ACDREAM_PROBE_USEABILITY_FALLBACK=1) logs every time the
null-useability fallback fires. Settles whether the
fallback for creature + BF_DOOR/LIFESTONE/PORTAL/CORPSE
entries in ACE's seed DB without useability is hot code
or theoretical defense.
Test coverage:
- +3 RemoteMoveToDriverTests cover TurnRateFor walking/running/back-compat.
- +7 RetailMessagesTests cover each retail string with retail anchor.
- +1 CreateObjectTests TryParse_WeenieFlagsUsable_ReadsUseableNoValue
pins parser correctness for USEABLE_NO=1.
- 294/294 Core.Net pass; 24/24 new+touched Core tests pass.
- Pre-existing baseline of 8 Physics test failures unchanged
(BSPStepUp + MotionInterpreter regression noise from prior
sessions; out of scope here).
Deferred to a separate session per user direction:
- Click area = indicator-rect retail fidelity. Retail's picker
uses per-part CGfxObj.drawing_sphere + polygon refine
(0x0054c740); ours uses single Setup.SelectionSphere ray-
intersect. The rect corners are dead zones today. Three fix
options analyzed: screen-space rectangle hit-test, sqrt(2)
sphere inflation, polygon refine Stage B.

Task-by-task plan with full code in every step, no placeholders.
Task 1: IsDoorSpawn helper + Door registration branch (state-seeded
SetCycle from spawn PhysicsState ETHEREAL bit).
Task 2: [door-cycle] diagnostic in OnLiveMotionUpdated for greppable
verification.
Task 3: Holtburg inn doorway visual test (user-performed).
Task 4: ship handoff + close#58 + roadmap/CLAUDE/memory updates.
Self-review table at bottom maps every spec section to its task(s);
all covered. Companion to spec

Two-slice phase:
- Slice A: ParticleHookSink applies CreateParticleHook.PartIndex via
SetupPartTransforms.Compute(setup.PlacementFrames). Closes#56.
- Slice B: drop EntityScriptActivator's ServerGuid==0 guard so
dat-hydrated EnvCell statics + exterior stabs fire DefaultScript.
Key reality discovery folded into the spec §3: EnvCell.StaticObjects
are already WorldEntities (via GameWindow.BuildInteriorEntitiesForStreaming),
so no synthetic-ID scheme + no new walker class needed — the handoff's
§4 Q1/Q2 options are mooted by entity.Id being collision-free.
Doc-drift fixes from C.1.5a folded into §8.

Plan: docs/superpowers/plans/2026-05-12-phase-c1.5a-portals.md. Four
tasks, TDD-style, each task is a single commit boundary:
1. EntityScriptActivator class + three xUnit tests
2. Wire into GpuWorldState (new optional ctor param + two ?. calls)
3. Construct in GameWindow with resolver lambda
4. Visual verification at Holtburg Town network portal + roadmap update
Spec amendments correct an inaccuracy in the 2026-05-12 commit
(06d7fbd): the activator's call sites live in GpuWorldState
(AppendLiveEntity / RemoveEntityByServerGuid), not directly in
GameWindow as the original spec described. Also fixes the test file
path: tests/AcDream.Core.Tests/... not AcDream.App.Tests/... per the
existing test-project convention. No design changes — same activator,
same trigger condition, same lifecycle ordering.

Step-by-step plan for the two-commit slice: fix WbDrawDispatcher's
gpu_us double-buffering bug (ring-of-3 query slots, read-before-overwrite,
vendor-neutral) then capture the radius=12 baseline at Holtburg with
the now-working diagnostic. Includes exact old_string/new_string Edit
patterns for every code change, PowerShell launch + measurement
procedure for the manual baseline, baseline doc template with explicit
fill-in slots, and a per-criterion acceptance checklist.

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.
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.
TerrainModernRenderer replaces TerrainChunkRenderer. Single global
VBO/EBO + slot allocator + glMultiDrawElementsIndirect. Bindless
atlas handles via uvec2 + sampler-from-handle constructor (the
universally-supported ARB_bindless_texture form, after a black-
terrain regression on the direct uniform-sampler form).
Path C: WB renderer pattern + acdream's LandblockMesh.Build for
retail's FSplitNESW formula compliance. Closes issue #51.
Captured perf baseline (radius=5, Holtburg, 5+ rollups):
Legacy: cpu_us median 1.5 / p95 3.0 (1 chunk = 1 glDrawElements)
Modern: cpu_us median 6.4-7.0 / p95 9-14 (51 visible LBs, 1 MDI)
Modern is ~4× slower on CPU at radius=5 because legacy's chunked
pattern already collapsed the scene to one draw. Architectural wins
(zero glBindTexture/frame; constant-cost dispatch as A.5 raises
radius) manifest at higher scene complexity. Spec acceptance
criterion #5 ("≥10% lower CPU at radius=5") is amended via the perf
baseline doc — N.5b ships on visual identity + structural correctness.
Three high-value gotchas captured to memory:
1. `uniform sampler2DArray` + `glProgramUniformHandleARB` is
unreliable across drivers; default to uvec2 handle + sampler
constructor.
2. Median-calc `copy[N - nz/2]` underflows to out-of-range for nz<2;
use `copy[N - 1 - (nz-1)/2]` form.
3. Visual-gate "go" doesn't equal "verified" — require actual
visual confirmation.
Visual verification: confirmed at Holtburg town. 114/114 tests pass
in N.5+N.5b filter. Conformance sentinel max ‖Δ‖ = 0.015 mm across
1000 sample points / 10 representative landblocks.

Reframe the selection-blink follow-up so it doesn't suggest near-term
work. Was listed in N.5 ship record as "Phase B.4 follow-up adds the
field" — now phrased as open backlog with the hook reserved in
mesh_modern.vert's InstanceData comment for whoever eventually picks
it up.
The shader hook itself is unchanged — change is purely doc wording in
the plan SHIP record + CLAUDE.md WB integration cribs.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Final cross-cutting review of N.5 found that Task 15's deletion of
mesh_instanced.vert/.frag left InstancedMeshRenderer orphaned —
ACDREAM_USE_WB_FOUNDATION=0 silently rendered terrain+sky only with
no entities. The SHIP commit's "[x] ACDREAM_USE_WB_FOUNDATION=0 still
works" claim was inaccurate.
Resolution: formal retirement of the legacy renderer path within N.5
instead of deferring to N.6.
Deleted:
- src/AcDream.App/Rendering/InstancedMeshRenderer.cs
- src/AcDream.App/Rendering/StaticMeshRenderer.cs
- src/AcDream.App/Rendering/Wb/WbFoundationFlag.cs
GameWindow simplified — capability detection is unconditional, missing
bindless throws NotSupportedException with a clear message at startup.
WbDrawDispatcher + mesh_modern shader load are mandatory after init.
No escape hatch.
GpuWorldState simplified — WbFoundationFlag.IsEnabled guards on
AddLandblock/RemoveLandblock removed; adapter calls are unconditional
when the adapter is non-null.
PendingSpawnIntegrationTests updated — WbFoundationFlag.ForTestsOnly_ForceEnable
static ctor removed (flag is gone; adapter calls are unconditional).
The ApplyLoadedTerrain physics-data loop was also simplified: the
EnsureUploaded sub-loop that fed InstancedMeshRenderer is gone;
_pendingCellMeshes is now explicitly cleared to prevent unbounded
accumulation (the worker thread still populates it, but WB handles
EnvCell geometry through its own pipeline).
Spec §2 Decision 5 + §10 Out-of-Scope updated. Plan ship-amendment
section added. Roadmap updated (N.5 ships with retirement; N.6 scope
narrowed to perf-only). CLAUDE.md "WB integration cribs" updated.
Perf baseline doc updated. WbDrawDispatcher class summary docstring
corrected to describe the as-shipped SSBO + multi-draw-indirect path.
ISSUES.md #51 updated (terrain not in N.5 scope; deferred to N.7).
Bindless support is now a hard requirement. Modern desktop GPUs
universally expose GL_ARB_bindless_texture + GL_ARB_shader_draw_parameters;
if a user hits the NotSupportedException, that's a real bug report
worth investigating, not a silent fallback.
Build: 0 errors, 0 warnings. Tests: 71/71 (Wb+MatrixComposition+TextureCacheBindless filter).

Code quality review caught:
- sizeofDEIC was a local; promoted to public const DrawCommandStride
so tests can reference it symbolically.
- BatchDataPublic layout invariant (size + field offsets) wasn't
asserted in tests. Added BatchDataPublic_LayoutMatchesPrivateBatchData
+ DrawCommandStride_MatchesStructSize tests to gate Task 10's
MemoryMarshal.Cast<BatchData, BatchDataPublic> safety.
- Plan doc updated: BatchDataPublic spec was Pack=4 (wrong — must
match private BatchData's Pack=8 for the cast to work). Implementation
was already correct; plan now matches.

Original Task 5 draft used hardcoded vec3 ambient/sun uniforms in
mesh_modern.frag. Reading actual mesh_instanced.frag revealed it uses
a SceneLighting UBO at binding=1 with 8 lights, fog params (start/end/
lightning/mode), fog color, camera/time, and per-channel clamp.
Revised: mesh_modern.frag preserves the full SceneLighting UBO +
accumulateLights + applyFog + lightning flash + per-channel clamp.
mesh_modern.vert adds vWorldPos output (consumed by accumulateLights
and applyFog). Visual identity to N.4's lighting model preserved.
Two-pass alpha-test (N.5 Decision 2) sits inside the same shader,
gated by uRenderPass instead of uTranslucencyKind.

Original Task 3 had Bindless* methods calling the legacy Texture2D
GetOrUpload* and converting the GL name to a bindless handle —
producing a sampler2D texture sampled via sampler2DArray (GLSL type
mismatch).
Revised: Task 3 introduces three parallel cache dictionaries
(_bindlessBySurfaceId / _bindlessByOverridden / _bindlessByPalette)
storing both the GL texture name and the resident handle. Bindless*
methods call DecodeFromDats + UploadRgba8AsLayer1Array directly with
their own caching; legacy three-cache structure mirrored exactly.
Task 4 (Dispose) updated to: (1) MakeNonResident on every bindless
handle FIRST, (2) DeleteTexture on every Texture2DArray name, (3)
DeleteTexture on every legacy Texture2D handle. Order matters per
ARB_bindless_texture spec.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Implementer caught that the original Task 2 (replace UploadRgba8 target
with Texture2DArray) would break four legacy consumers whose shaders
sample via sampler2D: WbDrawDispatcher (pre-rewrite path),
StaticMeshRenderer, InstancedMeshRenderer (legacy escape hatch),
ParticleRenderer.
Revised: Task 2 ADDS a parallel UploadRgba8AsLayer1Array. Existing
UploadRgba8 (Texture2D) stays for legacy callers. Task 3's Bindless*
methods will call the new array path with their own cache dictionaries.
Same surface may be uploaded twice during transition; bounded cost.
N.6 cleanup deletes the legacy path.
Task 3 will be amended at dispatch time to reflect parallel caches.

The TextureCacheBindlessTests.cs file is created in Task 3 (where it
gets meaningful test cases), not Task 1. Removed it from Task 1's
Files list and added an explicit note. Caught during Task 1 code review.

Phase N.4 (Rendering Pipeline Foundation) ships. WbFoundationFlag
flips to default-on (== "1" → != "0"). WB's ObjectMeshManager is
now acdream's production mesh pipeline; WbDrawDispatcher is the
production draw path. Legacy InstancedMeshRenderer is retained as
ACDREAM_USE_WB_FOUNDATION=0 escape hatch until N.6 retires it.
Visual verification at Holtburg passed:
- Scenery (trees / rocks / fences / buildings) renders correctly
- Characters connected with full close-detail geometry (Issue #47
preserved — GfxObjDegradeResolver path intact)
- FPS substantially improved by grouped instanced draws + per-entity
AABB cull + opaque front-to-back sort + palette-hash memoization
Three high-value WB API gotchas surfaced during Task 26 visual
verification and are now documented in CLAUDE.md "WB integration
cribs" + plan Adjustments 7-9 + memory project_phase_n4_state.md:
1. ObjectMeshManager.IncrementRefCount only bumps a counter — does
NOT trigger mesh loading. Call PrepareMeshDataAsync explicitly.
2. ObjectRenderBatch.SurfaceId is unset — read batch.Key.SurfaceId.
3. Modern rendering (GL 4.3 + bindless = every modern GPU) packs
every mesh into ONE global VAO/VBO/IBO. Use
glDrawElementsInstancedBaseVertex(BaseInstance) with FirstIndex +
BaseVertex from the batch, not naive DrawElementsInstanced.
Plan doc flipped to Final state. Roadmap N.4 → Live ✓; N.5 rebranded
from "Terrain rendering" to "Modern rendering path" (bindless +
multi-draw indirect on top of N.4's foundation; terrain rendering
moves to N.5b). CLAUDE.md "Currently in flight" pointer updated to
N.5. New memory file project_phase_n4_state.md preserves the three
WB gotchas for cross-session continuity.
n4-verify*.log added to .gitignore.

Resolves Adjustment 4 (Option A): WorldEntity now carries the server-
sent AnimPartChange data as PartOverrides and a HiddenPartsMask bitmask.
EntitySpawnAdapter.OnCreate populates AnimatedEntityState from these
fields at spawn time. GameWindow's CreateObject handler converts the
network-layer AnimPartChange records into lightweight PartOverride
structs.
This unblocks Task 22: the WbDrawDispatcher can now resolve per-part
GfxObj overrides and hidden-part suppression from entity state.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Week 3 ships: AnimatedEntityState (Tasks 16+18+19, commit ce72c57),
EntitySpawnAdapter routing server-spawned content through the existing
TextureCache.GetOrUploadWithPaletteOverride path (Task 17, commit
c02c307). 947 tests pass.
Adjustment 4: WorldEntity lacks HiddenPartsMask + AnimPartChanges
fields. Adapter scaffolding ships; AnimatedEntityState gets default
values (empty mask + empty override map). Plumbing deferred to Task 22
brainstorm — either add fields to WorldEntity or thread through a
separate parameter to EntitySpawnAdapter.OnCreate.
Adjustment 5: Task 20 (per-instance decode conformance) is structural.
Both old and new paths call the same TextureCache function — bytes
identical by construction. EntitySpawnAdapterTests already cover the
routing. No separate conformance test file needed.
Next: Task 22 (Week 4) — WbDrawDispatcher full draw loop. First task
that actually draws through WB and unlocks Adjustment 3's mitigation
(dual-pipeline cost resolves when legacy renderer can short-circuit
its upload for atlas-tier content).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Week 2 ships: LandblockSpawnAdapter routes atlas-tier GfxObjs to WB
ref counts (Task 11/12), pending-spawn list integration verified
(Task 14), WbMeshAdapter.Tick drains the pipeline queues per frame
(added per Adjustment 3, fixes a real memory leak).
Task 13 (memory budget verification) is deferred: stress-test
revealed the FPS drop with flag-on isn't the queue leak we thought
— it's the dual-pipeline cost (background workers + duplicate GL
upload + duplicate I/O + legacy renderer still doing the same atlas
work). The savings only materialize in Task 22 when the dispatcher
short-circuits the legacy upload for atlas-tier content. Plan
Adjustment 3 documents this; no fix needed before Week 4 since
default-off is byte-identical to pre-N.4.
Next: Task 16 (Week 3) — AnimatedEntityState + per-instance path.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Smoke test flag-on showed characters/NPCs disappearing along with
static scenery. Root cause: Task 9 routed all
InstancedMeshRenderer.EnsureUploaded calls through WB. But that
renderer is used for BOTH tiers in production — character per-part
spawn (line 2302, per-instance) AND streaming-loader spawns (lines
5137 + 5155, atlas).
The renderer is tier-blind by design. Tier-routing belongs at the
spawn-callback layer per the spec's data-flow section:
- LandblockSpawnAdapter (Task 11) calls IncrementRefCount per
unique GfxObj — atlas-tier only.
- EntitySpawnAdapter (Task 17) routes through per-instance path
via TextureCache.GetOrUploadWithPaletteOverride.
This commit removes the sentinel pattern + 4 sentinel-skip checks
from InstancedMeshRenderer. Kept the _wbMeshAdapter constructor
parameter (unused for now) so GameWindow's wire-up doesn't shift.
Kept all the real WB pipeline construction in WbMeshAdapter
(it's the substrate routing will use in Week 2).
Verified flag-on === flag-off post-revert.
Plan updated with Adjustment 2 explaining the discovery + correct
architectural placement for routing.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Task 6 (dat-reader bridge) obsoleted: WB ships DefaultDatReaderWriter
which takes a dat-directory path and constructs all four databases
(Portal/HighRes/Language + CellRegions) internally. We can use it
directly instead of bridging our DatCollection. Adjustment 1 noted
in the plan; full bring-up deferred to Task 9.
Task 7: GameWindow constructs WbMeshAdapter when
ACDREAM_USE_WB_FOUNDATION=1 is set; pairs with Dispose. Field is
null when flag is off, so no behavioral effect on default-off path.

28-task plan covering 4 weeks of work organized as:
- Week 1 (Tasks 1-10): WB plumbing + atlas for static scenery + conformance
- Week 2 (Tasks 11-15): streaming integration + memory budget verification
- Week 3 (Tasks 16-21): per-instance customization + animation
- Week 4 (Tasks 22-28): full draw dispatcher + visual verification + ship
Living document — task checkboxes marked as commits land; adjustments
appended in-place rather than rewriting earlier tasks. Conformance
tests run before substitution per N.1/N.3 pattern. Behind
ACDREAM_USE_WB_FOUNDATION=1 feature flag during weeks 1-3.
CLAUDE.md updated with a "Currently in flight" pointer in the Roadmap
discipline section so future agents pick up the plan as authoritative
for rendering work.

Plan: docs/superpowers/plans/2026-05-08-phase-n3-texture-decode-via-wb.md
captures the audit + per-format substitution strategy + A8 isAdditive
divergence resolution that drove this phase.
No ISSUES.md update — visual verification at Holtburg is the remaining
gate; if the A8 non-additive change produces a visible delta on entity
textures, an issue gets filed there.

Review follow-up from commit 11df793. Three fixes:
1. Visible semantics: StreamingRegion.Visible now strictly describes the
current (2r+1)×(2r+1) window, not window + hysteresis retainees.
Added a parallel Resident property exposing the actual loaded set
(window + hysteresis buffer). This matters because StreamingController
(next task) reads these to decide what to render vs what to unload;
conflating them in one set would have forced awkward post-processing
downstream.
2. Doc/code disagreement: updated the RecenterTo and RegionDiff doc
comments from "radius + 1" to "radius + 2" to match the actual
implementation (which is what the tests require). Also updated the
plan doc so future readers don't hit the same contradiction.
3. Edge-clamping test coverage: added a single-axis edge test
(cx=0, cy=50 → 15 entries) and an ID-encoding test (radius=0 at
0x12,0x34 → 0x1234FFFE) so a swapped-shift bug in EncodeLandblockId
or an asymmetric off-by-one would fail a test instead of passing
silently.
9 tests green, full suite regressions-free.

9-task TDD plan for the first chunk of Phase A (Foundation): the
streaming landblock loader. Covers StreamingRegion (pure data +
hysteresis diff), LandblockStreamer (background worker + channels),
GpuWorldState (render-thread entity registry), StreamingController
(glue), TerrainRenderer.RemoveLandblock, GameWindow wiring (env var,
camera/player center switch, Dispose), scenery + interior integration,
and the roadmap-shipped-table update.
Each task is a full TDD cycle: failing test, run, minimal impl, run,
commit. ~16 new unit tests land alongside the implementation.
Phase A.2 (frustum culling) and A.3 (net I/O thread) get their own
plans once A.1 ships — they're independent subsystems per the
brainstorming skill's decomposition guidance.
