Visual test surfaced two B.7 MVP issues:
1. Box anchored at abdomen + fixed 48px size meant the rectangle
shrank visually as the camera approached the entity (entity got
bigger on screen, box stayed 48px → triangles ended up inside
the silhouette).
2. Origin was a single point (entity position + 0.9m WorldVerticalOffset)
so the box wasn't centred on the visible body.
Fix: project both feet (WorldPosition) and head (WorldPosition.Z +
EntityHeight=1.8m) to screen space. Apparent pixel height between the
two = box height; halve it for width (WidthHeightRatio=0.5 ≈
humanoid). Box centred at midpoint of projected feet+head.
- Closer entity → bigger projected height → bigger box. Distance
scaling is automatic from the perspective projection.
- Farther entity → smaller projected height → MinScreenHeight=16px
floor prevents the box collapsing to a point.
- Box is screen-axis-aligned (always rectangular on screen) but
sized + positioned by the entity's actual world-space silhouette.
Properties exposed (TriangleSize, EntityHeight, WidthHeightRatio,
MinScreenHeight) so the panel can be tuned per-instance if a future
caller wants short-item boxes (drop EntityHeight to ~0.3m for tapers,
keep WidthHeightRatio at 1.0 for a square box).
Stuck-on-+Je issue (clicking other things still returns +Je) is
Issue #59 — picker over-pick — and unaffected by this commit.
Per the B.7 design spec, wires a Vivid-Target-Indicator-style overlay
into GameWindow's ImGui pass:
TargetIndicatorPanel (src/AcDream.App/UI/TargetIndicatorPanel.cs)
- Three delegates injected from GameWindow:
selectedGuidProvider -> _selectedGuid
entityResolver -> (worldPos, itemType, pwdBits) from
_entitiesByServerGuid + _liveEntityInfoByGuid
+ _lastSpawnByGuid
cameraProvider -> (view, projection, viewport) from
_cameraController.Active + _window.Size
- Per-frame Render():
* Bail on null selection / despawned entity / zero viewport.
* Project entity world position (+0.9m mid-body offset) to NDC.
* Bail off-screen (no edge arrow in MVP).
* Convert to viewport pixel coords, draw 4 right-angle triangles
at corners of a 48px square around the projected center.
* Colour from RadarBlipColors.For(itemType, pwdBits).
GameWindow wiring:
- Construct _targetIndicator right after _panelHost during ImGui init.
- Call _targetIndicator?.Render() between _panelHost.RenderAll and
_imguiBootstrap.Render — draws to the ImGui background list so
docked panels can occlude the indicator if they overlap.
Build green. Core.Tests went 1046 -> 1054 (+8 RadarBlipColors tests
from the prior commit). Baseline failures unchanged at 8.
Visual verification next: launch, click an NPC → yellow corners; click
an item -> white corners; deselect -> corners disappear.
Static helper resolving a target indicator / radar blip colour from
ItemType + the raw PublicWeenieDesc._bitfield acdream already parses
onto EntitySpawn. Dispatch order matches retail decomp at 0x004d76f0:
Portal (BF_PORTAL = 0x40000) → cyan
Vendor (BF_VENDOR = 0x200) → green
Creature && !IsPlayer → yellow
Player + IsPK (BF_PLAYER_KILLER = 0x20) → red
Player + IsPKLite (= 0x2000000) → pink
Player (other) → white (Default)
Otherwise (item / object) → light grey
RGBA values are hand-tuned to visually match retail screenshots; the
real RGBAColor_Radar* constants live in retail static data and can be
swapped in later without breaking call sites.
8 unit tests cover the full type/flag matrix (item, NPC, friendly
player, PK, PKLite, vendor, portal-priority-over-flags).
Next: TargetIndicatorPanel (App, ImGui draw) that uses this lookup.
User-observed behaviour: 'When at a distance X it should start running
towards the double clicked target and then stop close to it. When at a
shorter distance it should walk to it.' That's retail's MoveToManager
behaviour driven by the wire's WalkRunThreshold field, which Slice 2
ignored (it always synthesised Run=true regardless of distance).
ACE's defaults (MoveToParameters.SetDefaults): WalkRunThreshold=15.0 m
for Use/PickUp paths — so close-range auto-walks are walks, not runs.
ACE's combat-charge override: 1.0 m — chase runs until the last metre.
Both retail and ACE compute Run vs Walk per-frame from remaining
distance vs threshold.
Wire WalkRunThreshold:
- Already parsed into CreateObject.MoveToPathData.WalkRunThreshold.
- Now plumbed through to PlayerMovementController.BeginServerAutoWalk
as a new parameter, stored in _autoWalkWalkRunThreshold.
- ApplyAutoWalkOverlay sets Run = (dist > _autoWalkWalkRunThreshold)
per frame. The synthesised input flips Run as the body approaches.
The motion-interpreter pipeline downstream picks RunForward vs
WalkForward from input.Run, so the animation cycle naturally switches
as the body crosses into the walk band. Run rate falls back to the
local PlayerWeenie.InqRunRate as before (ACE sends mtRun=0.00 for
Use/PickUp, so we never read mtRun; this is unchanged from Slice 2).
[autowalk-begin] diagnostic now includes walkRunThresh={x:F2} so the
threshold is visible alongside dest/minDist/objDist in the trace.
Prior trace (launch-slice2.log) showed ACE follows every mt=0x06
MoveToObject immediately with an mt=0x00 InterpretedMotionState
(cmd=0x0007 RunForward, fwdSpd=2.86) — the locomotion echo for the
same auto-walk, NOT a cancel. My wiring was treating the second
packet as 'server intent changed' and calling EndServerAutoWalk,
which killed the auto-walk on frame 1. Result: [autowalk-begin]
immediately followed by [autowalk-end reason=motion-non-moveto] and
zero visible motion.
Remove the over-eager cancel. The two natural cancel paths remain:
arrival detection inside ApplyAutoWalkOverlay, and user-input
cancellation (any movement key). A fresh MoveToObject re-targets via
BeginServerAutoWalk overwrite, which is the correct sticky-targeting
behavior.
Retail-faithful per MovementManager::PerformMovement (0x00524440 case 6,
decomp 300628-300648): when ACE broadcasts MoveToObject for the local
player, the local client runs its OWN auto-walk on its OWN body —
heading correction toward the target, run-forward velocity, arrival
detected via the wire's min_distance / distance_to_object predicates.
Implementation:
PlayerMovementController:
+ IsServerAutoWalking property (read-only)
+ BeginServerAutoWalk(destWorld, minDist, objDist, moveTowards)
+ EndServerAutoWalk(reason) // idempotent, logs to [autowalk-end]
// when ACDREAM_PROBE_AUTOWALK is on
+ ApplyAutoWalkOverlay(dt, input) — called at the top of Update.
- User movement key (Forward/Backward/Strafe/Turn) cancels.
- Arrival predicate matches RemoteMoveToDriver / retail.
- Heading steered toward destination at ±20° snap-on-aligned
tolerance / π/2 rad/s rotation rate (same constants the
remote-creature path uses).
- Synthesizes input as Forward+Run; the rest of Update's
MotionInterpreter + body-velocity pipeline runs unchanged.
GameWindow.OnLiveMotionUpdated (local-player branch):
+ when update.MotionState.IsServerControlledMoveTo and MoveToPath
is populated: translate origin to world via RemoteMoveToDriver
.OriginToWorld, call _playerController.BeginServerAutoWalk.
+ when a non-MoveTo motion arrives and auto-walk is active:
EndServerAutoWalk(reason="motion-non-moveto").
+ [autowalk-begin] trace line under ACDREAM_PROBE_AUTOWALK.
The mtRun=0 case from the spec trace is handled implicitly: this
slice doesn't read MoveToRunRate at all — it relies on the existing
input.Run path which uses the player's local InqRunRate (env-var
defaulted to 200). Future slice can layer in mtRun!=0 honor if needed.
Slices 3 (animation cycle source while auto-walking) and 4 (local
pickup animation echo for #64) deferred to follow-up commits.
Wires PhysicsDiagnostics.ProbeAutoWalkEnabled into the DebugVM + ImGui
panel checkbox alongside the existing Probe Resolve / Probe Cell /
Probe BSP hits checkboxes. Following the L.2a + L.2d pattern: the
panel toggle takes effect live (no relaunch needed) because the
diagnostic call sites read the static flag every frame.
Lets the next B.6 trace session toggle the probe via panel checkbox
when ACDREAM_DEVTOOLS=1, without an env-var dance.
Per the B.6 design spec (now retail-grounded on Option A), slice 1 is
pure-additive logging so the next session has a clean trace of what
ACE actually sends to the local player during a server-initiated
auto-walk.
New PhysicsDiagnostics.ProbeAutoWalkEnabled static flag, env-var-
initialized from ACDREAM_PROBE_AUTOWALK=1. Probe sites:
[autowalk-out] on SendUse + SendPickUp — the packets that trigger
ACE's CreateMoveToChain when the target is out of WithinUseRadius.
[autowalk-mt] on OnLiveMotionUpdated for _playerServerGuid only —
captures MovementType + MoveToPath origin/min-dist/obj-dist +
moveTowards + speed/runRate. Lets us see exactly the wire data
retail's PerformMovement case 6 (0x00524440) was acting on.
[autowalk-up] on OnLivePositionUpdated for _playerServerGuid only —
cadence + payload of ACE's position broadcasts during auto-walk.
No behavior change. All flags off by default; opt in with the env var
during a focused reproduction. Designed to be mirrored into DebugVM
checkbox state later (parallel to ProbeResolve / ProbeCell / ProbeBuilding)
but not wired yet — env-var-only for the first trace session.
B.4c sets Animation = null! for sequencer-driven door entities (sites
at line 2867 + 7892), but the declared type is non-nullable. Today
doors never enter _remoteDeadReckon (ACE doesn't send UpdatePosition
for them), so the PARTSDIAG block's unguarded read is unreachable —
but the moment something flips that, ACDREAM_REMOTE_VEL_DIAG=1 would
NRE the tick.
Local-var + is-not-null check keeps the guard scoped to this block;
the legacy slerp branch downstream still treats ae.Animation as
non-null per its declared type, so the flow analysis doesn't propagate
nullable warnings to unrelated sites.
The previous "Can't pick that up" toast wasn't retail behavior either —
retail silently dropped the malformed pickup with no client-side
feedback. Drop the toast, keep the guard. The user learns by trying
again (which IS the retail UX). Filter still prevents the malformed
packet from reaching ACE, so the WeenieError 0x0029 + NPC-emote chain
that originally surfaced this bug stays suppressed.
Visual test surfaced a UX bug: when the user single-clicked an NPC last
before pressing F, _selectedGuid carried over to SendPickUp and the
client sent PutItemInContainer(itemGuid = NPC's serverGuid, ...). ACE
responded with WeenieError 0x0029 (Stuck — "You cannot pick that up!")
AND triggered the NPC's emote chain, producing the confusing
"NPCs talk to me when I press F" symptom.
F is only for ground items. Use (double-click) is the right action for
NPCs and is unaffected. Guard SendPickUp with the existing
IsLiveCreatureTarget predicate and show a toast instead. Same defensive
pattern as the 'Not in world' / 'Nothing selected' guards already
present in SendUse / SendPickUp / OnInputAction.
After B.5 shipped, the actual pickup was invisible feedback-wise: the
item left the ground, ACE despawned it via PickupEvent (0xF74A), and
the ItemRepository got updated — but the player had no visual
acknowledgement that anything happened. The M1 demo's "pick up an
item" target visually felt like the item just vanished into the void.
Add a new EntityPickedUp event to WorldSession that fires from the
PickupEvent (0xF74A) dispatch branch BEFORE EntityDeleted, so the
subscriber can still read the entity's display name from
_entitiesByServerGuid before the despawn handler clears it.
GameWindow subscribes during the live-session wiring block and emits
a retail-style system chat line plus a debug toast on every successful
pickup, mirroring retail behavior (retail synthesized this line
client-side; ACE doesn't echo it).
Closes the M1 demo "pick up" target's visible-payoff gap.
ACE sends GameMessagePickupEvent (opcode 0xF74A) instead of
GameMessageDeleteObject (0xF747) for items removed via player pickup
(Player_Tracking.RemoveTrackedObject with fromPickup=true).
Without this handler, BuildPickUp succeeded server-side (item moved
into the player's container, retail observers saw it disappear), but
our local client kept rendering it on the ground because the despawn
message went to the unhandled-opcode bucket.
PickupEvent's wire body adds an objectPositionSequence field on top
of DeleteObject's layout, so the parser is its own type. The
downstream view-removal semantics are identical to DeleteObject, so
the dispatcher routes both opcodes into the same EntityDeleted event
via a small adapter.
Visual test revealed doors rendered halfway in the ground because the
spawn-time SetCycle seed never fired:
- Spec specified NonCombat stance = 0x01, but ACE's MotionStance.NonCombat
is 0x3D (61). The cycle key is `0x80000000 | stance`, so the correct
initial style is 0x8000003D, not 0x80000001.
- HasCycle(0x80000001, ...) always returned false -> SetCycle was skipped
-> sequencer left with no current motion -> Advance(dt) returned empty
frames -> per-frame MeshRefs rebuild at line 7691 set every part to
(origin, identity) -> door parts collapsed to the entity origin (which
sits at the door's pivot, halfway underground for inn doors).
Fix:
1. Rename inline `NonCombatStance` -> `NonCombatStyle` and use the correct
0x8000003D value.
2. Defensively prefer spawn.MotionState?.Stance when present (the wire
may carry an explicit non-NonCombat stance for unusual doors), falling
back to NonCombat. Mirrors OnLiveMotionUpdated's existing pattern at
line 3148: `uint fullStyle = stance != 0 ? (0x80000000u | (uint)stance) : ae.Sequencer.CurrentStyle`.
3. Extend [door-anim] registered diagnostic to include initialStyle so
future visual tests can verify the stance value at a glance.
Verified by reading the prior visual test's log: ACE broadcasts UMs
with stance=0x003D and the runtime sequencer keyed cycles by
style=0x8000003D. Same value now used at spawn.

Code-quality review of the [door-cycle] diagnostic flagged three items:
- Important: open-coded doorInfo.Name == "Door" duplicated IsDoorSpawn's
predicate. Introduces IsDoorName(string?) as the shared core both
IsDoorSpawn and the diagnostic call.
- Minor: the diagnostic's comment said "Phase B.4c" which rots after
archival; rewrite to use the durable [door-cycle] grep target instead.
- Minor: the diagnostic re-read update.MotionState.Stance / ForwardCommand
instead of the stance/command locals every other diagnostic in the
method uses. Switched to the locals for pattern consistency.
No behavior change. Build green; tests 1046/8 baseline unchanged.

Logs one line per UpdateMotion arriving for an entity named "Door"
when ACDREAM_PROBE_BUILDING=1. Greppable trail for the B.4c visual
test: confirms the dispatcher hit the sequencer for door open / close.
Durable subsystem-named tag per the Opus reviewer's B.4b feedback
([B.4c] would rot after phase archival; [door-cycle] survives).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds IsDoorSpawn helper and a sibling branch to the live-spawn
handler's animation registration gate. Detects entities where
spawn.Name == "Door" and registers them in _animatedEntities with an
AnimationSequencer seeded from the spawn PhysicsState's ETHEREAL bit
(Off cycle if closed, On if already open).
Mirrors ACE Door.cs:43 (CurrentMotionState = motionClosed) so the
sequencer always has frames for the per-frame tick to advance from
the first render. Without the seed, Advance(dt) returns no frames and
the MeshRefs rebuild at line 7691 collapses the door to origin.
No changes to OnLiveMotionUpdated, AnimationSequencer, EntitySpawnAdapter,
or the per-frame tick. The tick's sequencer branch at line 7497 reads
ae.Sequencer.Advance(dt) and never touches ae.Animation in this path
(only the legacy slerp else branch at line 7644+ does).
[door-anim] registered diagnostic gated on ACDREAM_PROBE_BUILDING.
One spec deviation: Animation = null! (null-forgiving) instead of
Animation = null — AnimatedEntity.Animation is a required non-nullable
field; null! is the same pattern used at line 7857 for sequencer-driven
AnimatedEntity registrations in the same file.

B.4b visual test revealed the L.2g pipeline was a phantom:
- Server SetState arrives with parsed.Guid = ServerGuid (0x7A9B4015)
- ShadowObjectRegistry keys by local entity.Id (0x000F4245)
- UpdatePhysicsState(0x7A9B4015, ...) misses the lookup -> no-op
- Cached state stays 0x00010008 forever
- CollisionExemption.ShouldSkip sees the unchanged state
- Door keeps blocking the player
Translate in OnLiveStateUpdated by looking up the WorldEntity via
_entitiesByServerGuid and using entity.Id as the registry key.
Also extends the [setstate] diagnostic to include entityId=0x... so
the next visual-test grep can confirm the translation lands.
This was the actual blocker the user reported as "I cant go through
it" -- ACE was flipping ETHEREAL, our pipeline acknowledged it in the
diagnostic, but the cached state for the resolver-side check never
moved. Both L.2g slice 1's unit tests and slice 1b's collision
exemption widening were correct in isolation; the integration between
them was broken by the ID-space mismatch.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
B.4b visual test confirmed the L.2g slice 1 handoff's open question:
ACE's Door.Open() broadcasts state=0x0001000C (HasPhysicsBSP |
Ethereal | ReportCollisions), NOT the state=0x14+ that retail servers
send (Ethereal | IgnoreCollisions). The L.2g pipeline correctly
mutates ShadowObjectRegistry with the new state, but
CollisionExemption.ShouldSkip required both bits and the door stayed
solid.
Retail (acclient_2013_pseudo_c.txt:276782) wraps FindObjCollisions in
`if NOT (state & ETHEREAL && state & IGNORE_COLLISIONS)`. ETHEREAL
alone takes a different retail path at line 276795 that sets
sphere_path.obstruction_ethereal = 1 and lets downstream movement
allow passage despite the contact. We haven't ported that downstream
path yet.
Pragmatic shortcut: widen the early-out to ETHEREAL alone so doors
become passable when ACE flips the bit. Retail-server broadcasts
still hit the same branch correctly (both bits set implies ETHEREAL).
Compatible with both server styles.
Renames test EtherealOnly_NotSkipped -> EtherealOnly_Skipped and
flips its assertion. 13 CollisionExemption tests pass; full suite
1046 pass / 8 pre-existing baseline fail (unchanged).

GameWindow.OnInputAction had an early-return gate dropping every
non-Press activation. With the new InputDispatcher firing
SelectDblLeft as ActivationType.DoubleClick, the case in the switch
was unreachable -- visual test confirmed [input] SelectDblLeft
DoubleClick fired but [B.4b] pick never followed.
Fix: also let DoubleClick through the gate. The existing case label
matches on action (not activation), so SelectDblLeft fires
PickAndStoreSelection(useImmediately: true) as designed.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Visual test of the B.4b handler revealed the dispatcher never fired
SelectDblLeft. OnMouseDown was only looking up Press and Hold
activations — DoubleClick bindings in KeyBindings.cs were effectively
dead code.
Adds 500ms-threshold double-click detection: tracks last-mouse-down
button + Environment.TickCount64 timestamp; a same-button press within
the threshold additionally fires ActivationType.DoubleClick for the
matching binding (Press still fires normally for the second click).
Clears the pair-state after firing so a triple-click doesn't produce
a second DoubleClick.
Tests cover same-button within threshold, beyond threshold (no fire),
different-button (no fire), and triple-click (fresh pair required).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Closes#57. Adds three OnInputAction switch cases (SelectLeft,
SelectDblLeft, UseSelected) and three private helpers
(PickAndStoreSelection, UseCurrentSelection, SendUse). Single-click
selects but does not Use; double-click selects + Uses; R hotkey
sends Use on the existing _selectedGuid. ImGui mouse-capture
filtering already happens in InputDispatcher — no new guard needed.
Diagnostic lines emitted for log grep:
[B.4b] pick guid=0x{guid:X8} name={label}
[B.4b] use guid=0x{guid:X8} seq={seq}
Also adds a one-line doc comment on _selectedGuid clarifying its
dual-purpose role (combat Q-cycle + interaction click), per the Task 3
review.
Build green; tests 1046/1054 (8 pre-existing-baseline fails
unchanged). Switch-case behavior verified at runtime via the Holtburg
inn doorway visual test (per spec §Testing → Runtime verification).

Retail's selection model is a single "current target" used by combat,
interaction, NPC dialog, and HUD alike - not two parallel selections.
Renames the existing combat-only field on GameWindow so the upcoming
B.4b click handler and the existing Q-cycle SelectClosestCombatTarget
share the same selection state.
Mechanical rename, no behavior change. Build + tests green.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Code review flagged two latent correctness bugs in Pick:
1. The single t = -b - sqrt(d) intersection skipped entities whose
5m bounding sphere contained the ray origin. Realistic at
point-blank range — if the player stands within ~5m of a door,
the near-plane sits inside the door's bounding sphere and the
door becomes unpickable. Standard fix: when t_near < 0 fall
through to t_far = -b + sqrt(d) (the sphere exit point).
2. The discriminant formula assumes |direction| = 1. BuildRay
currently normalizes so the assumption holds at the wire, but
the contract wasn't documented. Added an explicit
<param name="direction"> note.
New test Pick_RayOriginInsideEntitySphere_StillReturnsServerGuid
covers the inside-sphere case. Suite: 9/9 WorldPicker tests pass.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds Pick(origin, direction, candidates, skipServerGuid, maxDistance)
to AcDream.Core.Selection.WorldPicker. Iterates candidates, skips
entities with ServerGuid==0 (atlas/dat-hydrated statics — no server
identity) and the caller's skipServerGuid (the player self).
Geometric ray-sphere intersection at 5m radius (matches
WorldEntity.DefaultAabbRadius). Returns the nearest hit's ServerGuid
within maxDistance (50m default), or null on miss.
6 xUnit tests added: hit, miss, two-in-line-returns-closer, skip-guid,
skip-zero-server-guid, beyond-max-distance.

New AcDream.Core.Selection.WorldPicker static helper. BuildRay
unprojects pixel (mouseX, mouseY) through a view+projection matrix
pair into a world-space (origin, direction) ray. Used by
GameWindow.OnInputAction to drive entity picking on click.
Pure math, no state, no DI. Composes view*projection (System.Numerics
row-vector convention, matching the rest of acdream's camera path —
see GameWindow.cs:6445 FrustumPlanes.FromViewProjection). 2 xUnit
tests cover center-of-viewport (forward ray) and right-of-center
(positive-X deflection).

Two changes folded into one commit:
1. GameWindow subscribes to WorldSession.StateUpdated and routes the
parsed (guid, newState) pair into
ShadowObjectRegistry.UpdatePhysicsState. End-to-end wiring complete:
server SetState (0xF74B) -> WorldSession dispatcher -> StateUpdated
event -> GameWindow handler -> registry mutation -> next resolver
tick sees the new ETHEREAL bit and CollisionExemption short-circuits
the door cylinder. After this commit the M1 'open the inn door'
scenario is unblocked at the code-path level; visual verification
follows in Task 7 (user-driven).
The handler also emits a [setstate] diagnostic line when
ACDREAM_PROBE_BUILDING is enabled, giving a greppable trail when
the visual test runs.
2. Slice 0.5 freebie folded in: the [entity-source] probe lines now
include state=0x... flags=... so ETHEREAL flips are greppable
end-to-end from spawn through state change. Resolves the 'slice
1.6' suggestion from the L.2d ship handoff
(docs/research/2026-05-13-l2d-slice1-shipped-handoff.md).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three changes folded into one commit:
1. New public StateUpdated event on WorldSession + dispatcher branch
for op == SetState.Opcode. Mirrors the VectorUpdated /
MotionUpdated event pattern. GameWindow will subscribe in the next
commit and feed the parsed (guid, newState) pair to
ShadowObjectRegistry.UpdatePhysicsState.
2. One-shot probe-gated hex-dump (ACDREAM_PROBE_BUILDING) emits the
first inbound SetState message's body bytes. Originally planned
as a separate slice 1.5 confidence-check on holtburger's claimed
12-byte payload vs ACE's GameMessageSetState.cs. Folded into the
dispatcher to avoid re-touching the same branch. The new
_setStateHexDumped guard keeps the log clean — auto-close every
30s would otherwise produce noise.
3. Doc-comment polish on SetState.cs requested by Task 1's code
review: remove false uncertainty about ACE's sequence-field width
(ACE's UShortSequence.CurrentBytes provably writes 2 bytes via
BitConverter), and align the 'total body size' phrasing with
VectorUpdate.cs's convention. Folded here to avoid churning the
file twice this slice.

New mutator that overwrites cached PhysicsState bits on every shadow copy
of the named entity. The existing CollisionExemption.ShouldSkip(...) check
(acclient_2013_pseudo_c.txt:276782) reads the same cached field, so a
post-spawn ETHEREAL flip is now honored on the next resolver tick without
any resolver-path change.
Retail anchor: CPhysicsObj::set_state at acclient_2013_pseudo_c.txt:283044.
Slice 1 scopes to the bare state-write — retail's cosmetic side-effect
handlers (0x800 lighting, 0x20 nodraw, 0x4000 hidden) don't fire for the
ETHEREAL bit and stay deferred.
Three TDD tests cover: ETHEREAL flip from 0->0x4; unregistered-entity
no-op; entity spanning multiple cells gets all copies updated.

DTO + TryParse for the GameMessageSetState wire message. The server
broadcasts this when an already-spawned entity's PhysicsState changes
post-CreateObject — chiefly when a door's Ethereal bit toggles on Use.
Wire format per holtburger SetStateData (validated against retail-format
servers): u32 opcode + u32 guid + u32 state + u16 instanceSequence + u16
stateSequence = 16 bytes total. Mirrors the existing VectorUpdate.cs
template.

First Holtburg-doorway capture showed all 191 [resolve-bldg] entries
labeled "n/a (cylinder)" — including hits attributed to the building
0xA9B47900 which [entity-source] confirmed was registered as type=BSP.
The label was a probe bug, not a real cylinder route.
Root cause: BSPQuery's grounded-path (Path 5) returns early via
`StepSphereUp(transition, worldNormal, engine)` when no step is already
in progress. The slice-1 side-channel write at line 1546 came AFTER
that early return, so it never fired for the dominant grounded-player
case. Compounding: StepSphereUp recurses into ResolveWithTransition →
FindObjCollisions, whose per-entity `LastBspHitPoly = null` clear
wiped any earlier write before the outer attribution emitter read it.
Fix:
1. BSPQuery Path 5: move LastBspHitPoly write to the top of
`if (hit0 || hitPoly0 != null)` blocks (both foot- and head-sphere),
BEFORE the StepSphereUp early return. Recursion-safe — the inner
resolve's BSP writes will overwrite with the inner entity's poly,
but for the dominant case (same wall hit on both outer and inner)
that's still the correct attribution.
2. TransitionTypes.FindObjCollisions: drop the per-entity clear of
LastBspHitPoly. With BSPQuery now writing at hit-detection time
instead of response-computation time, the side-channel value is
reliable without per-iteration zeroing.
3. TransitionTypes [resolve-bldg] emission: key the "n/a (cylinder)"
label on `obj.CollisionType` directly, not on LastBspHitPoly being
null. A BSP entity with a null poly now logs "n/a (BSP path —
side-channel not written, missing BSPQuery wire site)" so any
future BSPQuery path that's missing the wire is visible in the
trace rather than being silently mis-labeled.
Verified: build green, the 2 slice-1 tests still pass, 8 pre-existing
failures unchanged.

Adds ACDREAM_PROBE_BUILDING — a read-only per-shadow-entry probe that
captures full BSP collision evidence whenever TransitionTypes.FindObjCollisions
attributes a hit (via the existing L.2a slice 3 chain). One multi-line
[resolve-bldg] entry per attributed hit: partIdx, hasPhys, bspR vs
vAabbR, world-space entOrigin_lb, and the actual hit polygon's vertices
in both object-local and world space.
Paired with a one-time [entity-source] line at every ShadowObjects.Register
call site in GameWindow so entityId from a probe line is greppable to its
WorldEntity source within a single log file.
Plumbing: BSPQuery writes the resolved hit polygon to a new
PhysicsDiagnostics.LastBspHitPoly side-channel at the 5 SetCollisionNormal
sites in Paths 5/6 + CollideWithPt. TransitionTypes clears that field
before each shadow-entry dispatch and reads it back at the L.2a slice 3
attribution site to emit the probe line.
Spec component 4 originally described an out ResolvedPolygon? parameter
on BSPQuery.FindCollisions; the static side-channel achieves the same
observable behavior without plumbing through BSPQuery's recursive private
methods. Deviation noted in PhysicsDiagnostics.LastBspHitPoly's XML doc.
Reframes the plan-of-record's L.2d sub-direction paragraph: the 2026-05-12
handoff proposed porting CBuildingObj + per-cell walkability, but ACE
BuildingObj.cs:39-52 + named-retail acclient_2013_pseudo_c.txt:701260
show find_building_collisions is one BSP test on Parts[0]. Per-cell
walkability belongs to L.2e, not L.2d. L.2d slice 1 is the diagnostic;
slice 2 is the actual fix scoped from slice 1's evidence (one of three
hypotheses: wrong BSP loaded / over-registered parts / BSPQuery flaw).
Tests: 2 synthetic unit tests in PhysicsDiagnosticsTests.cs pin the
static API contract that the BSPQuery → side-channel → TransitionTypes
emission chain depends on. The multi-line line format itself is verified
by acceptance criterion 2 (live Holtburg-doorway capture) — covering it
here would require a heavy PhysicsEngine + Transition fixture for a
diagnostic-only emission.
Verified: dotnet build green; the 2 new tests pass; the 8 pre-existing
test failures listed in the L.2a handoff (MotionInterpreter GetMaxSpeed_*,
PositionManager.ComputeOffset_BothActive_Combined,
PlayerMovementController.Update_ForwardInput_*, Dispatcher.W_held_*,
BSPStepUpTests.{D4,C3}) remain failing — none introduced by this slice.

The CollisionInfo.CollideObjectGuids list + LastCollidedObjectGuid
fields existed but were never written anywhere in the codebase — slice
2's [resolve] probe found this when 85 hit=yes lines came back with
no obj= attribution.
This commit fills the gap at the only place we have the attribution
data: the per-object iteration in Transition.FindObjCollisions, where
obj.EntityId is in scope right after each per-object BSPQuery /
CylinderCollision call. Two cases trigger an Add():
- result != TransitionState.OK (object hard-blocked transition)
- normal flipped invalid→valid during the call (BSPQuery captured
a slide normal without halting — covers wall-slide cases).
Beyond the diagnostic, this also fixes a quiet structural gap — any
future physics behavior that wants "who did I just collide with"
(PvP exemption sanity check, NPC bump rules, etc.) was previously
flying blind on stub fields. Now the data flows.
Build green. Will re-test the doorway with the same trace to get
the wall's entity id.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Extends the existing [resolve] probe line to surface
ci.LastCollidedObjectGuid (hit object) + ci.CollidedWithEnvironment
(terrain hit flag) + ci.CollideObjectGuids.Count (when >1) so the
operator can tell WHICH entity the wall is, not just the wall normal.
Tonight's L.2a slice 1 trace caught a clean wall-slide at the
Holtburg-area doorway (n=(0,1,0), 122 hit=yes lines), but had no way
to attribute the hit to a specific entity — the L.2d sub-direction
call (door collision shape vs building wall mesh) needs the entity id
to pick the right fix. This extension provides it on the next run.
Format change for [resolve] hit field:
Before: hit=yes n=(0.00,1.00,0.00)
After: hit=yes n=(0.00,1.00,0.00) obj=0xCC0CXXXX
hit=yes n=(0.00,1.00,0.00) env
hit=yes n=(0.00,1.00,0.00) obj=0xCC0CXXXX env nObj=3
Pure additive within the existing PhysicsDiagnostics.ProbeResolveEnabled
gate. No new env var, no new file. Build green.

New static `AcDream.Core.Physics.PhysicsDiagnostics` holds two
runtime-toggleable flags initialized from env vars:
- ACDREAM_PROBE_RESOLVE=1 — emit one [resolve] line per
PhysicsEngine.ResolveWithTransition call: input/target/output
position+cell, ok-vs-partial, grounded-in, contact-plane status,
wall normal if hit, walkable-polygon valid, moving entity id.
- ACDREAM_PROBE_CELL=1 — emit one [cell-transit] line per
PlayerMovementController.CellId change: old → new cell, current
world position, reason tag (resolver / teleport).
Both also exposed as runtime-toggleable checkboxes in the DebugPanel
"Diagnostics" section. Unlike the existing four Dump-* checkboxes
(which only mirror sticky-at-startup env vars), the two new ones
forward directly to PhysicsDiagnostics — toggling on/off takes
effect on the next physics resolve, no relaunch.
Why now: L.2's plan-of-record (docs/plans/2026-04-29-movement-collision-
conformance.md) explicitly says "Land L.2a diagnostics first. Do not
make another physics change blind." This slice closes the most-load-
bearing gap in L.2a — a general-purpose probe on the resolver outcome
and a cell-transit log — so that later L.2b/c/d/e physics changes can
be evidence-driven instead of guessed. Foundation for the indoor /
dungeon walking trajectory (G.3 unblock).
Pure additive: when both flags are off (default), the probes collapse
to a single static-bool read per resolve, zero log cost. PlayerMovement
Controller's two CellId-mutation sites are now routed through a
private UpdateCellId(reason) helper for diag chokepoint.
Build green, 1032/1040 unit tests pass. The 8 failing tests are
pre-existing on the branch base (verified by stash-and-rerun);
none touch resolver or cell-transit code; all fail identically with
this slice stashed. Investigation deferred to a follow-up.

Four new foreach blocks in GpuWorldState wire EntityScriptActivator
into the dat-hydration spawn/despawn paths:
- AddLandblock: fires OnCreate for each entity with ServerGuid==0
(live entities filtered out — they got OnCreate at AppendLiveEntity
and would double-fire on pending-bucket merges).
- AddEntitiesToExistingLandblock: fires OnCreate for each entity in
the promoted batch (all dat-hydrated by construction).
- RemoveLandblock: fires OnRemove(entity.Id) for each ServerGuid==0
entity before the loaded record is dropped.
- RemoveEntitiesFromLandblock: fires OnRemove for the demote-tier
entities about to be cleared (Near→Far demotion).
5 new integration tests cover the four fire-sites + the no-double-fire
invariant on pending-bucket merges. Pattern matches existing
GpuWorldStateTests (stub LandBlock heightmap + WorldEntity factory).
Closes#56 end-to-end. Slice A (per-part transforms in Tasks 1-3) +
Slice B (dat-hydrated entity DefaultScript firing, this task) both
ready for visual verification at Holtburg portal + Inn fireplace +
cottage chimney + spell cast.
Note: 8 pre-existing failures in Physics/Input/MotionInterpreter test
families are unrelated to this work (verified by re-running with this
task's changes stashed).

Resolver returns ScriptActivationInfo(ScriptId, PartTransforms) — one
dat lookup per spawn yields both pieces of info. The C.1.5a ServerGuid==0
guard is relaxed: activator now keys by ServerGuid when nonzero, else
entity.Id, so dat-hydrated entities (EnvCell statics, exterior stabs)
flow through the same code path as server-spawned ones. PartTransforms
pushed into ParticleHookSink before scheduling Play, closing the
activator side of #56.
GameWindow resolver lambda upgraded: now constructs ScriptActivationInfo
from setup.DefaultScript.DataId + SetupPartTransforms.Compute(setup),
swallowing dat-lookup throws the same way C.1.5a did.
Tests: 4 existing tests updated for new ScriptActivationInfo signature;
3 new tests cover entity.Id keying for dat-hydrated entities, end-to-end
part-transform pipeline (resolver → sink → particle world position), and
OnRemove with an arbitrary caller-picked key. 77 Vfx+Meshing+Activator
tests green.
GpuWorldState fire-site wiring (Task 4) lands next.

Adds per-entity part-transform side-table mirroring _rotationByEntity.
SpawnFromHook now transforms the hook offset through partTransforms[partIndex]
before rotating to world space. Backwards-compatible: entities without
registered part transforms fall through to identity (pre-C.1.5b behavior),
so the existing C.1.5a rotation-seed test stays green.
Adds SetEntityPartTransforms public method. Cleared on StopAllForEntity
alongside the rotation entry.
2 new xUnit tests:
- SpawnFromHook_AppliesPartTransform_WhenRegistered — part 1 lifted +Z=1,
hook offset (1,0,0), PartIndex=1 → world (1,0,1).
- SpawnFromHook_FallsBackToIdentity_WhenPartIndexOutOfBounds — PartIndex=99
on a 2-part array → offset applied without crash, pre-C.1.5b behavior.
Closes the renderer side of #56. EntityScriptActivator wiring (Task 3)
lands next.

Computes Matrix4x4 per Setup part by walking PlacementFrames[Resting] →
[Default] → first-available, matching SetupMesh.Flatten's priority.
Foundation for #56 fix: ParticleHookSink will use these to apply each
CreateParticleHook's PartIndex-relative offset to the right mesh part.
4 xUnit tests cover Resting-over-Default preference, Default fallback,
empty-PlacementFrames returns empty, DefaultScale application.

Visual verification at the Holtburg Town network portal revealed the swirl
was oriented along world axes (NS) instead of the portal's actual facing
(EW), and partially buried in the ground because the hook's local-frame
Offset.Origin was being applied in world axes too.
Root cause: EntityScriptActivator.OnCreate fired _scriptRunner.Play but
never called _particleSink.SetEntityRotation. When the runner's
CreateParticleHook fires, the sink reads per-entity rotation from
_rotationByEntity (defaults to Quaternion.Identity for unknown entities)
and uses it to transform the hook's Offset.Origin from entity-local to
world space. Without the seed call, the rotation lookup falls through to
Identity and the offset goes off along world XYZ.
Fix is a single SetEntityRotation call before the Play call. Added a 4th
unit test that constructs an entity with a 90 deg yaw and asserts the spawned
particle's world position reflects the rotated offset.

Code-review follow-up to 65d833d:
ResolveDefaultScript was closing over its own var capturedDatsForActivator
= _dats, but the sibling SequencerFactory in the same block already
declared var capturedDats = _dats. The two locals pointed at the same
reference and served the same purpose; the alias added no value and
muddied the closure pattern.
Reuse capturedDats. No behavior change.

Wires the activator into the production lifecycle:
- Construct alongside _wbEntitySpawnAdapter using _scriptRunner +
_particleSink (both built earlier in OnLoad).
- Production resolver lambda hits _dats.Get<Setup>(...) wrapped in
try/catch returning 0 on miss/throw — matches ParticleRenderer's
defensive read pattern.
- Pass into GpuWorldState's new optional ctor parameter.
Closes the wiring half of C.1.5a. Visual verification at the Holtburg
Town network portal is the acceptance gate.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
GpuWorldState grows a fourth optional ctor parameter for the activator,
paralleling how EntitySpawnAdapter is plumbed. AppendLiveEntity calls
OnCreate after the existing _wbEntitySpawnAdapter?.OnCreate;
RemoveEntityByServerGuid calls OnRemove after the existing OnRemove.
Symmetric, same order, null-safe.
GameWindow still passes the old 3-arg ctor — activator construction +
wire-through lands in the next commit.

Code-review follow-up to 003c502:
1. Test 3 (OnRemove_StopsScriptsAndEmitters) now wires the runner into
the real ParticleHookSink instead of a RecordingSink, registers a
persistent EmitterDesc, lets the CreateParticleHook actually spawn an
emitter, then asserts the sink killed it after OnRemove. Previously
the test only verified runner-side state — sink.StopAllForEntity was
never observably exercised, so a regression dropping that call would
have passed silently.
2. Removed unused `using System.Numerics` from EntityScriptActivator.cs.
No production code changes. Tests 1 and 2 unchanged.

New ~50-line orchestrator that fires Setup.DefaultScript through the
already-shipped PhysicsScriptRunner on entity spawn and stops scripts +
live emitters on despawn. Resolver delegate avoids DatCollection coupling
so the class is fully unit-testable with stubs.
Three xUnit tests cover the three branches: fire-with-script,
no-op-without-script, stop-on-remove. No wiring into the live spawn path
yet -- that lands in the next commit.

Capture authoritative CPU+GPU dispatch numbers at Holtburg with the
gpu_us diagnostic now working (commit 25cb147). Three radii (4/8/12)
x two motion modes (standstill/walking) + a surface-format histogram
from ACDREAM_DUMP_SURFACES=1.
Adds env-gated one-shot dump path (TextureCache.TickSurfaceHistogramDumpIfEnabled,
called from GameWindow.OnRender) that fires once after both (a) frame
600 of the session AND (b) the upload-metadata dict reaches 100 entries
-- the cache-size gate prevents the dump from firing during pre-world
GUI ticks where OnRender spins at high rates but no scenery has streamed.
Output writes to %LOCALAPPDATA%\acdream\n6-surfaces.txt with a try/catch
around the I/O so disk-full / permission errors don't crash mid-measurement.
Baseline document at docs/plans/2026-05-11-phase-n6-perf-baseline.md
documents:
- CPU dominates GPU by 30-50x at every radius (strongly CPU-bound)
- GPU wildly under-utilized (max gpu_us p95 ~600us vs 16,600us frame budget)
- CPU scales superlinearly with N1 (Tier 1 cache wins on inner loop but
not outer LB walk)
- Surface atlas opportunity high (59% of textures in top-3 triples) but
win is memory-only since GPU isn't bottlenecked
Recommendation: C.1.5 (PES emitter wiring) next, then a reduced-scope
N.6 slice 2 (drop atlas + persistent-mapped buffers -- not justified by
the GPU under-utilization observed).
Roadmap entry amended to split N.6 into slice 1 (shipped) and slice 2
(planned, reduced scope, deferred until after C.1.5).

Code-quality review on Task 1 (commit a7c9800) flagged an asymmetric
diag gate: the read-before-overwrite block at the top of the dispatcher
was not gated on diag, but the frame-counter increment and BeginQuery
calls were. If a maintainer toggled ACDREAM_WB_DIAG from "1" to "" mid-
session, _gpuQueryFrameIndex would freeze (gated inside if(diag)) while
the read kept firing every frame at the same slot — producing duplicate
stale samples.
Add diag to the read block's outer condition so the read/issue/increment
trio is symmetric. One-line change; behavior under the normal usage
pattern (env var set at launch, never toggled) is unchanged.
