Per-step subagent-driven plan for the render half: T0 test-hygiene baseline,
Stage 3 render-root unification (root at CellGraph.CurrCell + seen_outside, drop
the FindCameraCell grace-frame fallback), Stage 4 PView seal (sky/landscape inside
the portal-clip bracket + conditional doorway Z-clear = no blue-hole; EnvCellRenderer
GL_BLEND verify), Stage 5 entity/particle cell-clip. Key reframe from grounding the
plan in the actual code: the PView infra (PortalVisibilityBuilder BFS + OutsideView,
ClipFrame, EnvCellRenderer GL_BLEND fix, WbDrawDispatcher cell gate) ALREADY EXISTS and
the A8 stencil split is already gone — so the render half is wire-and-fill-gaps, not a
from-scratch port. Execution policy: no intermediate user gates, single final visual
verification, full suite green at verification.

Bite-sized TDD plan for design Stages 0-1 + W2b revert + visual gate: add the
[cell-swept] diagnostic, return the swept sp.CurCellId from ResolveWithTransition
(retail SetPositionInternal), revert the superseded W2b hysteresis, visual-gate the
doorway/cellar strobe, then lock it with a doorway replay regression. Render chunk
(Stages 3-5) gets its own spec+plan after this gate.

8 TDD tasks (RED->GREEN), Core-only, zero behavior change, built alongside the legacy cell systems. Grounded in the retail CObjCell survey + acdream inventory + #98 fixtures.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Five tasks: (1) RED apparatus reproducing the doorway flap on a synthetic
C0->C1->C2(exit) chain; (2) Layer 1 LoadedCell.VisibleCells + SeenOutside
plumbing; (3) oracle-ported PVS grounding of set membership (the fix, gated by
task 1); (4) seen_outside invariants (sealed=empty, threshold=stable); (5)
live [vis] + visual gate. Task 3 is a faithful port (add_views 433382 /
InitCell 432896 / ClipPortals 433572), pseudocode-first, not fabricated.

The plan's Task 2 code block still showed moverFlags: ObjectInfoState.None; the
shipped code (fcea05f) and spec §5.1 use IsViewer|PathClipped|FreeRotate|
PerfectClip (retail init_object(player, 0x5c)). Update the stale snippet so the
plan matches reality (this stale block was the likely source of a re-report).

Bite-sized TDD plan for the swept-sphere camera collision: CollideCamera flag,
ICameraCollisionProbe + PhysicsCameraCollisionProbe (reuses ResolveWithTransition),
RetailChaseCamera slot-in, GameWindow wiring, Camera-menu toggle, visual
acceptance. Also refines the spec from planning findings: the InitPath +radius
sphere-center offset (ToSpherePath/FromSpherePath z-shift) and the deterministic
probe test scope (z-offset round-trip + cellId==0 guard; collision correctness
rides the existing sweep suite + visual).

Lands the working A8 indoor-rendering and streaming fixes accumulated this
session. User has verified these visually to some degree (e.g. lifestone /
translucent meshes confirmed fine under the FrontFace flip; bridge / wall /
collision regressions confirmed fixed after travel); not every path has been
exhaustively gated. The cellar-flap defect remains OPEN and will be solved
the retail-faithful way via a dedicated brainstorm (see handoff docs).
Rendering core (reviewed, high confidence):
- EnvCellRenderer SSBO stride fix: upload packed Matrix4x4[] (64B) instead of
the 80B CPU InstanceData struct the shader never expected — fixes the
transform/texture "explosion" for any draw with >1 instance (cells that
dedupe to a shared cellGeomId). Real root cause.
- WB-style global FrontFace(CW) + per-batch CullMode carried through the MDI
layout (GroupKey + BuildIndirectArrays + DrawIndirectRange split into
same-cull runs with absolute uDrawIDOffset per run).
- EntitySet partitioning (IndoorPass / OutdoorScenery / LiveDynamic) +
WorldEntity.BuildingShellAnchorCellId so building shells scope to their
dat-derived building cell instead of rendering everywhere.
- RenderOutsideInAcdream (look into buildings from outside) +
CollectVisiblePortalBuildings frustum cull of portal bounds.
- Sky-when-inside-building + per-cell audit probe + GL-state probe.
Streaming / perf (test-covered; not independently code-reviewed this session):
- Near/far priority queues so near work wins over far; PromoteToNear carries
full landblock + mesh data; LandblockEntriesWithoutAnimatedIndex avoids
rebuilding the animated-lookup dict in the hot draw path. Fixes the
bridge-not-appearing / missing-walls / broken-collision-after-travel
regressions and improves post-transition FPS.
Tooling + docs:
- tools/A8CellAudit: offline dat cell/portal/building dumper (portals +
buildings modes) — reproduces the cellar-flap investigation with no launch.
- docs/research cellar-flap root-cause + option-2 handoff (the didInsideStencil
double-duty finding + the WB-recursive design decision + brainstorm prompt),
entity-taxonomy, replan, issue-78 visibility investigation.
Diagnostics retained on purpose: ACDREAM_A8_DIAG_* gates, portal_stencil.vert
provisional pos.w clamp, and the probe families are kept (env-var gated, zero
cost when off) because the pending option-2 cellar-flap brainstorm needs them.
Strip in the option-2 ship commit.
Indoor branch stays behind ACDREAM_A8_INDOOR_BRANCH=1 (default off = pre-A8
visual). Build green; App tests + Core (streaming/dispatcher/loader) tests pass.

Replaces the four reverted RR7 variants from 2026-05-27 with a
verbatim port of WB VisibilityManager.RenderInsideOut.
Plan covers 10 tasks across 5 dependency waves:
- Wave 1 (tasks 1-4, 7): extract WbRenderPass, WbFrustum,
EnvCellSceneryInstance/EnvCellLandblock, EnvCellVisibilitySnapshot;
add IndoorCellStencilPipeline.RenderBuildingStencilMask
- Wave 2 (task 5): build EnvCellRenderer with inline RenderModernMDI
- Wave 3 (task 6): wire EnvCellRenderer into landblock streaming
- Wave 4 (task 8): port RenderInsideOutAcdream byte-for-byte
- Wave 5 (task 9): probe trail [envcells]/[stencil]/[draworder]/[buildings]
- Wave 6 (task 10): probe-gated visual verification launch
Process rules carved from RR7 saga:
- No visual gate without probe data first
- No partial WB ports (Steps 1-5 ship together)
- No conceptual adaptations
- Trust-but-verify after every subagent

Session-end documentation for the issue #100 ship and the visibility-
culling investigation handoff for the next session.
Three documents land together:
- docs/superpowers/plans/2026-05-25-issue-100-terrain-cutout.md
(the 3-task plan that drove this session's f48c74a / a64e6f2 /
84e3b72 — never committed by Tasks 1-2)
- docs/research/2026-05-25-issue-100-terrain-cutout-handoff.md
(the predecessor session's smoking-gun research that drove the
#100 fix — never committed by the prior session)
- docs/research/2026-05-25-issue-100-shipped-and-culling-handoff.md
(THIS session's handoff: what shipped, what visual-verification
surfaced, the issue family map for #78 + #95 + the new cellar-
stairs finding, root-cause hypothesis, retail anchors, WB
references, do-not-retry list, and pickup prompt for the next
session's investigation + plan + implementation)
Plus two updates to existing files:
- CLAUDE.md — adds a ship paragraph for #100 to the M1.5 progress
block. References the new handoff doc as the next-session pickup
point.
- docs/ISSUES.md #78 — broadens scope from "outdoor stabs visible
through floor" to "outdoor stabs + terrain mesh visible inside
EnvCells". Adds the 2026-05-25 cellar-stairs evidence (per user
direction: not filed as new issue; treated as evidence
reinforcing #78's hypothesis #2). Promotes hypothesis #2 to
"high confidence as of 2026-05-25" and adds the retail anchor
(acclient_2013_pseudo_c.txt:311397 CEnvCell::find_visible_child_cell).
Acceptance criteria broadened to include the cellar-stairs case.
Next session: pickup prompt at the bottom of the new handoff doc
drives a /investigate → writing-plans → subagent-driven-development
pass on indoor-cell visibility culling — the work that closes#78
+ cellar-stairs together, and possibly #95 if the infrastructure
overlaps.

Adds one log line per AdjustOffset call (gated by ACDREAM_PROBE_STEP_WALK)
naming the branch taken (no-cp / no-cp-slide / slide-degenerate /
slide-crease / into-plane / away-plane, optionally +safety-push) plus
zGain = output.Z - input.Z.
No math or control-flow changes — pure observability so the next capture
can disambiguate the three failure-mode hypotheses for the cellar-ramp
climb cap. Re-reading the existing capture (a6-issue98-negpoly-...log)
showed the sphere DOES climb 90.00 -> 92.79 (2.79 m gain), then caps,
contradicting the divergence comparison's "no altitude gain" framing.
The real question is what stops the climb at world Z ~= 92.79 with the
cottage floor still 1.21 m higher. Existing [step-walk] probes wrap
AdjustOffset; this new probe reveals which branch the projection takes.
Fix plan with the four-branch decision tree at
docs/superpowers/plans/2026-05-23-a6-p3-issue98-cellar-up-fix.md.
Test baseline maintained: 1167 + 8.

15-task TDD plan covering the three pieces of A6.P1:
Phase A — Build the [push-back] acdream probe (Tasks 1-9):
toggle + 3 helpers + 3 emission sites in BSPQuery/Transition,
DebugVM mirror, CLAUDE.md env-var docs.
Phase B — Build the cdb infrastructure (Tasks 10-12):
7-BP cdb script, PowerShell runner, README.
Phase C — Execute 9 captures + findings stub (Tasks 13-15):
PDB-match verify, capture dir + findings stub, scenario captures.
API surface verified against current code: ResolvedPolygon has no
Id property (probe omits poly attribution; cross-ref via time-
adjacent [push-back-cell] line). CheckOtherCells locals are
sp.CheckCellId + cellId + result (verified at TransitionTypes.cs
lines 1418-1473). SpherePath has Collide/InsertType/WalkInterp,
ObjectInfo has State (verified).

Plan: 7 tasks decomposing spec T2..T9 with bite-sized TDD-style steps,
exact file paths, commit-message templates, and a T4 safety-check
branch (refactor in place if ObjectMeshManager._dats call sites <=20;
fall back to thin adapter otherwise).
Spec fix: §4.1 mesh-pipeline files now correctly placed under
src/AcDream.App/Rendering/Wb/ instead of Core (ObjectMeshManager uses
Silk.NET.OpenGL types from Managed* wrappers, and CLAUDE.md forbids
Core depending on GL). §4.2's layer split (TextureHelpers in Core,
rest in App) was already correct.
Plan task order: T2 (setup) -> T5 (Core helpers, lowest risk) ->
T3 (App GL infra) -> T4 (App mesh pipeline + dat-shim) -> T7 (drop
refs + cleanup) -> T8 (visual verification) -> T9 (ship). T5 moved
earlier than spec order to validate the namespace migration flow on
small-blast-radius files before the load-bearing T4.
Self-review: all 12 spec decisions (O-D1..O-D12) mapped to plan tasks;
placeholders intentional + explained (MIT license body fetched at T2
step 4; commit-message parameters filled at task close).

ISSUES #83 Phase A1. Landblock stabs (entity.Id 0xC0XXYY00+n per
LandblockLoader.cs:55) were being registered with TWO collision
shadows: the correct per-part BSP at `entity.Id*256 + partIdx`, AND a
redundant mesh-AABB-fallback cylinder at `entity.Id`. The fallback
clamped to 1.5m radius, centered at the building's mesh origin,
producing user-reported "thin air" collisions inside cottages and
within 2m of building exteriors.
The fallback was originally designed for canopy-only-BSP procedural
scenery (0x80XXYY00+n) — trees whose BSP covers the canopy but not
the trunk. Landblock stabs have full BSP coverage and don't need it.
Probe evidence (launch-thinair capture):
- 0xC0A9B479 cylinder fallback (Holtburg cottage): 104 hits in a
short capture session, all inside the cottage main room
(cell=0xA9B4013F), ~2m from the building's mesh origin.
- 0xA9B47900 BSP (the actual cottage walls): 52 legitimate hits.
Fix: one new bool _isLandblockStab + one clause in the existing
mesh-AABB-fallback gate.

Three docs from the indoor walk-miss probe spike landed in commits
27c7284..a2e7a87:
- Spec: design of the [walk-miss] + [floor-polys] diagnostic emissions
with the H1/H2/H3 disambiguation matrix.
- Plan: 3-task TDD implementation plan (flag, aggregator, emissions).
- Findings: live-capture analysis showing H3 (walkable_hits_sphere /
adjust_sphere_to_plane synthesis rejection) is the dominant defect.
817 of 876 ground-contact misses (93%) cluster at dz~0.48 m, while
the 7 HITs all sit at dz~0.46 m — a 2 cm boundary between working
and broken that points at the sphere-overlap math, not the probe
distance. H1 (multi-cell iteration missing) is real but only 3%
of misses, secondary. H2 (probe distance) ruled out.
Next step: line-by-line decomp comparison of FindWalkableInternal /
walkable_hits_sphere / adjust_sphere_to_plane against retail at
acclient_2013_pseudo_c.txt:322032 / :323006 / :326793, then design
the fix in a follow-up session.

three fix commits + docs. Tasks 1-6 land the [indoor-bsp] probe in
one feature commit. Task 7 is the user-run capture gate. Tasks 8-11
do post-capture diagnosis + fix for #84 and #85 (with a route-δ
escape hatch if #85's fix turns out to be a large cross-cell port).
Tasks 12-13 ship the WorldPicker cell-BSP occlusion fix for #86

Six tasks:
1. Add exception-surfacing ContinueWith in WbMeshAdapter.IncrementRefCount
for EnvCell ids when ProbeIndoorUploadEnabled is on. Logs
[indoor-upload] FAILED + [indoor-upload] NULL_RESULT.
2. Capture procedure: user walks Holtburg with the probe on; analyze log.
3. Write cause report documenting the captured exception type(s).
4. Apply targeted fix (4a/4b/4c/4d sub-shapes for the 4 most-likely causes
— choice driven by Task 2's data). Or 4d: re-design if cause is none
of the above.
5. Verification: re-capture confirms completed lines, user visually
confirms floor in Holtburg Inn.
6. Roadmap update.
Tasks 2 and 5 are user-driven (must walk the client). Tasks 1, 3, 4, 6
can be subagent-dispatched.

Closes#63, #69, #74, #75. Replaces the chain of Commit-B workarounds
that compensated for ACE's MoveToChain getting cancelled by a leaked
user-MoveToState packet during inbound auto-walk. The fix is
architectural — auto-walk drives the body directly from the
server-supplied path data, no player-input synthesis, no spurious
wire-packet transitions, no grace-period band-aid.
Architectural change (closes#75):
PlayerMovementController.ApplyAutoWalkOverlay → DriveServerAutoWalk.
- Steps Yaw toward target at retail-faithful turn rates.
- Computes desired forward velocity from path runRate.
- Calls _motion.DoMotion(WalkForward, speed) directly for the
motion-interpreter state (drives animation cycle).
- Sets _body.set_local_velocity directly when grounded.
- Returns true to gate the user-input motion + velocity section
in Update so user-input flow doesn't overwrite auto-walk
velocity or motion state.
Mirrors retail's MovementManager::PerformMovement case 6 (decomp
0x00524440) which never touches the user-input pipeline during
server-controlled auto-walk.
Wire-layer guard at GameWindow.cs:6419 retained as a SEMANTIC
statement (`if (result.MotionStateChanged && !IsServerAutoWalking)`):
user-MoveToState packets are for user-driven motion intent. During
server-controlled auto-walk, the motion-state transitions caused by
the animation override (RunForward / WalkForward / TurnLeft /
TurnRight cycles) must not leak as user-cancellation packets. This
is NOT the deleted 500ms grace-period band-aid; it's the wire-layer
expressing the user-vs-server motion split.
Animation plumbed for auto-walk phases (closes#69):
- Moving forward → WalkForward (speed=1.0) / RunForward (speed=runRate)
- Turn-first phase → TurnLeft / TurnRight (sign of yawStep)
- Aligned-but-pre-step / arrival → no override (idle)
Driven via _autoWalkMovingForwardThisFrame + _autoWalkTurnDirectionThisFrame
fields set in DriveServerAutoWalk and read in the MovementResult
construction at the bottom of Update. UpdatePlayerAnimation picks up
the localAnimCmd as the highest-priority animation source.
Walk/run threshold = 1.0m, retail-observed. ACE's wire-default of
15.0f is too generous; ACE's own physics layer uses 1.0f at
MovementParameters.cs:50 (with the 15.0f line commented out) and
Creature.cs:312 notes "default 15 distance seems too far". The
formula matches retail's MovementParameters::get_command at decomp
0x0052aa00: running = (initialDist - distance_to_object) >=
threshold, evaluated ONCE at chain start and held for the rest of
the auto-walk (matches retail "runs all the way / walks all the way"
behaviour). Wire-supplied threshold is ignored.
Pickup gate (IsPickupableTarget) now uses BF_STUCK
(acclient.h:6435, bit 0x4) to discriminate immovable scenery from
real pickup items that share a Misc ItemType. Sign (pwd=0x14 with
BF_STUCK) → blocked; spell component (pwd=0x10, no BF_STUCK) →
allowed. ACE's PutItemInContainer (Player_Inventory.cs:831-836)
responds with WeenieError.Stuck (0x29) on stuck items so the gate
prevents wasted wire packets + a UX dead-end.
R-key dispatch by target type. UseCurrentSelection's top-level
IsUseableTarget gate was wrong (blocked USEABLE_NO=1 items that
ARE pickupable). Reordered:
1. Creature → SendUse
2. Pickupable → SendPickUp
3. Useable → SendUse
4. Otherwise → "cannot be used" toast
Each handler keeps its own gate. Matches retail's per-action
server-side validation.
AP cadence revert (closes#74). With the MoveToChain race fixed,
the per-frame "send while moving" cadence is no longer load-bearing.
Reverted to retail's two-branch ShouldSendPositionEvent gate
(acclient_2013_pseudo_c.txt:700233-700285):
Interval NOT elapsed (< 1 sec): send if cell or contact-plane changed.
Interval elapsed (>= 1 sec): send if cell or position frame changed.
Adds _lastSentContactPlane field + ApproxPlaneEqual helper +
PlayerMovementController.ContactPlane public accessor. Extended
NotePositionSent(Vector3, uint, Plane, float) — both outbound sites
(MoveToState + AP) pass _playerController.ContactPlane.
Effective rates: 0 Hz idle, ~1 Hz smooth motion, per-event on
cell/plane changes, 0 Hz airborne.
CLAUDE.md updated with no-workarounds rule (commit `da126f9` on
the worktree branch). Saved as feedback memory at
memory/feedback_no_workarounds.md.
Tests: build green; Core.Net 294/294; Core 1073/1081 (baseline,
8 pre-existing Physics failures unchanged). Visual-verified
end-to-end on 2026-05-16 for far/near Use + PickUp on NPCs,
doors, items, spell components, signs (correctly blocked), corpses,
turn-first animation, run/walk thresholds, idle quiet, smooth-
motion 1Hz.

Retires divergences flagged in the 2026-05-16 faithfulness audit:
1. AP cadence. Replaces the 1 Hz idle / 10 Hz active flat heartbeat
with a diff-driven model gated on `Contact && OnWalkable`
(acclient_2013_pseudo_c.txt:700327 SendPositionEvent). Sends on
position or cell change while grounded on walkable, plus a 1 sec
heartbeat; suppressed entirely airborne. PlayerMovementController
exposes `NotePositionSent(pos, cellId, now)` which GameWindow stamps
after each AutonomousPosition / MoveToState send — mirrors retail's
shared `last_sent_position_time` between SendPositionEvent
(0x006b4770) and SendMovementEvent (0x006b4680). Known divergence
from retail: ours is per-frame-while-moving, retail's effective rate
is ~1 Hz during smooth motion (cell/plane checks). Filed as #74,
blocked by #63 — when #63 lands we revert to retail's narrower gate.
2. Workaround retirement. Removes TinyMargin (0.05 m inside arrival)
and the AP-flush before re-send (`SendAutonomousPositionNow`). The
diff-driven cadence makes both obsolete. Close-range turn-first
deferred Use is kept (it IS retail — ACE Player_Move.cs:66-87
mirrors retail's CreateMoveToChain pre-callback rotation), renamed
`OnAutoWalkArrivedSendDeferredAction` to clarify it's a FIRST send.
`isRetryAfterArrival` parameter dropped.
3. Far-range Use/PickUp retry. Restored — was load-bearing, not the
"redundant cleanup" the Group 2 audit thought. Issue #63 means ACE
drops the first Use as too-far without re-polling on subsequent APs;
the arrival re-send is what makes far-range Use complete. Logs
include `(queued for arrival re-send pending #63)` to make this
explicit. Removes when #63 closes.
4. Screen-rect picker. New `AcDream.Core.Selection.ScreenProjection`
helper shared by `WorldPicker` and `TargetIndicatorPanel`. The
`Setup.SelectionSphere` projects to a screen-space square (retail
anchor `SmartBox::GetObjectBoundingBox` 0x00452e20); picker
hit-tests the mouse pixel against the same rect the indicator draws,
inflated by 8 px (`TriangleSize`). Guarantees what-you-see is
what-you-click — including rect corners that were dead zones under
the old ray-sphere picker. Per-type radius (1.0/1.6/2.0 m) and
vertical-offset (0.2/0.9/1.0/1.5 m) heuristic lambdas retired;
`IsTallSceneryGuid` deleted; `EntityHeightFor` trimmed to 1.5 m × scale
defensive default. No defensive sphere synth — entities without a
baked `SelectionSphere` are skipped, matching retail's
`GfxObjUnderSelectionRay` (0x0054c740).
5. Rotation rate run multiplier (Commit A precursor). `TurnRateFor(running)`
helper applies retail's `run_turn_factor = 1.5f` (PDB-named
0x007c8914) under HoldKey.Run, matching `apply_run_to_command` at
0x00527be0 (line 305098). Effective: walking ≈ 90°/s, running ≈ 135°/s.
Keyboard A/D + ApplyAutoWalkOverlay both use it.
6. Useability gate (Commit A precursor). `IsUseableTarget` corrected to
`useability != 0` per `ItemUses::IsUseable` at 256455 — ANY non-zero
passes (USEABLE_NO=1, USEABLE_CONTAINED=8, etc.), not just the
USEABLE_REMOTE bit. Cross-checked against 4 call sites in retail
(ItemHolder::UseObject 0x00588a80, DetermineUseResult 0x402697,
UsingItem 0x367638, disable-button-state 0x198826). Added
`ProbeUseabilityFallbackEnabled` diagnostic
(`ACDREAM_PROBE_USEABILITY_FALLBACK=1`) to measure how often the
creature/BF_DOOR fallback fires for ACE-seed-DB entities with
null useability.
CLAUDE.md updated with the graceful-shutdown rule for relaunch:
Stop-Process bypasses the logout packet, leaving ACE's session marked
logged-in for ~3+ min. CloseMainWindow() sends WM_CLOSE so the
shutdown hook runs and the logout packet reaches ACE.
Tests: +3 ScreenProjectionTests + 6 WorldPickerRectOverloadTests = +9.
Core.Net 294/294 pass; Core 1073/1081 (8 pre-existing Physics failures
unchanged). Visual-verified 2026-05-16: rotation rate, useability,
screen-rect click area, double-click + R-key + F-key Use/PickUp at
short and long range — dialogue/door/pickup fire on arrival.
Filed follow-ups #70 (triangle apex/size DAT sprite), #71 (picker
Stage B polygon refine), #72 (cdb omega.z probe), #73 (retail-message
sweep pattern), #74 (per-frame AP chattier than retail — blocked by
#63). Old ray-sphere `WorldPicker.Pick(origin, direction, ...)`
overload kept for back-compat; no callers in acdream proper.

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
docs/superpowers/specs/2026-05-13-phase-b4c-design.md.

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.
Output companion to docs/superpowers/specs/2026-05-11-phase-n6-slice1-design.md
(commit 05d590c).

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.
