The Town Network hub (498 registered fixtures) starved the player's own
room: BuildPointLightSnapshot's player-nearest-128 cap sorts by raw
Euclidean distance, which isn't a reliable proxy for "same room" in a
dense maze — a fixture on the other side of a wall can be geometrically
closer than the room's own torches and win the cap. LightSource.CellId
tagging and the [indoor-light] membership probe already existed from the
c500912b/#176 arc; the missing piece was a candidacy filter.
BuildPointLightSnapshot(playerWorldPos, visibleCells) now narrows
candidates to the frame's actual visible cells before the existing
dynamics-first player-nearest cap runs (cell-less lights, e.g. the viewer
fill, always included). GameWindow feeds LAST FRAME's already-rendered
RetailPViewFrameResult.DrawableCells — one frame of latency instead of
re-threading a mid-DrawInside callback, which was the exact mechanism
(c500912b) that caused the earlier #176 seam-floor flicker regression.
The distance-sort anchor stays the player, unchanged.
AP-85 updated in place (third revision) rather than adding a new row —
same underlying divergence, now with the render-visibility approximation
of retail's true DBObj-load/flush-bounded resident registry documented
alongside its residual risk (one unscoped frame on portal re-entry).
Core 2652+2skip / App 741+2skip / UI 425 / Net 385 green. Pending: user
visual gate at the Town Network fountain, and a #176 corridor-seam
non-regression recheck (Facility Hub, different landblock).

Lands the fading-secret-door feature and fixes the door "flip-back" that
surfaced while testing it.
#188 — fading-wall doors (e.g. "Pedestal Weak Spot") fade their wall part
out via TransparentPartHook instead of swinging:
- TranslucencyHookSink consumes TransparentPartHook -> TranslucencyFadeManager
(per-(entity,part) linear translucency ramp; holds at End frame).
- WbDrawDispatcher: new per-instance alpha SSBO (binding 7); ClassifyBatches
takes opacityMultiplier (1 - translucency, per CMaterial::SetTranslucencySimple
0x005396f0) forcing AlphaBlend; fully-invisible parts skipped.
- mesh_modern.vert/.frag: binding-7 InstanceAlphaBuf -> vOpacityMultiplier ->
FragColor.a *= vOpacityMultiplier.
- Register AP-89: the fade multiplies sampled texture alpha, not a separate
D3D9 material alpha channel (observably identical for texture-alpha==1 surfaces).
Door flip-back fix (affected BOTH #188 fading walls AND #187 sliding doors): a
door/wall that finished opening holds a single unchanging frame, so the
uncommitted IsEntityCurrentlyMoving cache-bypass narrowing dropped it onto the
Tier-1 static cache -- which only remembers the REST pose + opacity 1.0 --
snapping it visually shut/opaque while physics stayed open. Reverted that
narrowing: every Sequencer entity stays on the per-frame path (live pose + live
fade opacity), the known-good pre-optimization behavior. The per-frame CPU cost
that narrowing chased was a Debug-build artifact -- Release is GPU-bound
(~200 fps in Sawato, measured), so the unconditional add is free where it
matters. Left a code comment barring re-introduction.
Tests: full Core suite green (2649 passed, 2 skipped). Live visual gate PASSED --
both fading-wall and sliding doors hold open.

Collapse the two-path fork in RemotePhysicsUpdater.Tick: the former Path A
(grounded PLAYER remotes advanced by the interp catch-up with ResolveWithTransition
deliberately OMITTED, per the now-retired issue-#40 premise) is gone. Every remote --
player and NPC -- now runs the SAME per-tick catch-up + sweep + shadow-follows-resolved.
Retail's UpdateObjectInternal (0x005156b0) has no player/remote fork; this is the
faithful shape. Player remotes now get terrain-Z snap (no slope staircase), wall
collision, and MONSTER collision -- previously (Path A) they skipped ALL collision.
RETAIL PvP (adversarial review caught this): two non-PK players WALK THROUGH each
other in AC (you can stand inside another non-PK player) -- they do NOT de-overlap.
The remote-player mover now carries IsPlayer|EdgeSlide (mirroring the LOCAL player at
PlayerMovementController), so CollisionExemption's PvP block exempts a non-PK pair,
exactly as retail sets IsPlayer on every object's own transition (OBJECTINFO::init
0x0050cf30) and FindObjCollisions (pc:276812) exempts it. The first 2b draft passed
bare EdgeSlide and de-overlapped players (MORE solid than retail); the 3-lens review
flagged it. PK/PKLite/Impenetrable are not plumbed onto the remote mover yet -- the
same M1.5 gap the local player carries (TS-23, extended).
#40 proven dead in code (before the gate): PlayerVsMonster_DeOverlapsAndAbsorbsTheStallBlip
drives the real ComputeOffset -> InterpolationManager catch-up (incl. the fail_count
blip-to-tail) for a player mover converging on a monster and asserts de-overlap +
maxSpike<0.30 -- the sweep absorbs the stall-blip. ConvergingPlayers_WalkThroughEachOther
proves the PvP exemption (non-PK players pass through). Path B already ran the
#40-feared config stably; #40 (May 2026) predates the CSphere/#137/#170/#171 rebuild.
Placement (HIGH, review finding 3): the player UP routing gains the SAME placement-snap
backstop Slice 1 gave NPCs (AP-87). Without it a UM-first player (RemoteMotion seeded
to the spawn pos, then a first UP in a different cell) would sweep from a stale cell ->
garbage -> the digest's invisible/misplaced-player bug. The 4 m bodyToTarget guard +
!willBeDrTicked + dist>96 snap; near placed corrections still enqueue for smooth
catch-up. Also seed Body.Position=worldPos at UP-handler RemoteMotion creation
(mirrors the UM handler :5176) for the UP-first case.
Coupled shadow edits (research finding 9): RETIRED the players-only raw-worldPos shadow
sync -- now that players run the sweep + shadow-follows-resolved, the raw sync would
re-snap a packed player's shadow into overlap each UP. Player shadows follow the
RESOLVED body via the DR-tick loop + a new player UP-branch-tail SyncRemoteShadowToBody.
Surviving player/NPC split (AP-88): the omega -- grounded PLAYERS keep the
ObservedOmega-or-seqOmega world-frame (Concatenate) fallback ("rectangle when running
circles"); NPCs + airborne keep ObservedOmega-only body-frame (Multiply). They commute
for an upright body + yaw omega, so the fork is faithful.
Register: TS-23 extended (remote-player mover PK gap); AP-86 updated (raw sync retired
for players too, Where column fixed); AP-88 added (omega fork + eval-order note).
Tests: Core 2623 / App 741 green, 0 warnings. 3-lens adversarial review + per-finding
verification (10 agents); all 6 confirmed findings addressed (2 substantive: PvP mover
flags + player placement-snap; 4 doc/cosmetic).
VISUAL GATE (acceptance test) owed by the user -- NOTE the corrected expectation:
(a) a player remote on a hill -- no slope staircase;
(b) two packed player remotes -- they WALK THROUGH each other (retail PvP), NOT
de-overlap (this corrects the design's original "players de-overlap" gate);
(c) a player remote cannot stand inside a MONSTER (new: player-vs-monster collision);
(d) remote walk/run/jump/land/turn UNCHANGED.

The per-tick remote de-overlap sweep used a hardcoded HUMAN collision sphere
(0.48 m radius / 1.835 m capsule top) for EVERY creature, so large and small
monsters de-overlapped at human spacing (register TS-46). Retail seeds the
transition from the object's OWN Setup sphere list scaled by its wire ObjScale
(CPhysicsObj::transition 0x00512dc0 -> init_sphere(GetNumSphere, GetSphere,
m_scale); ObjScale from set_description 0x00514f40).
Slice 3 (one call site, no signature change): before the Path B ResolveWithTransition
call, read the creature's Setup-derived dims via the existing GetSetupCylinder
helper -- (setup.Radius, setup.Height) x ObjScale, the same source the local player
and the moveto/sticky radii already use, consistent with the spawn-time shadow
registration's entScale -- and pass them as sphereRadius/sphereHeight. Fall back to
the human capsule when GetSetupCylinder returns (0,0) for a shapeless / unresolvable
Setup (a zero radius would degenerate the sweep). The player call site is unchanged
(the player IS the human Setup). stepUp/stepDown stay 0.4 m (retail derives those
from the Setup too -- an adjacent divergence left as-is).
Big monsters now spread wider, small ones tighter -- the de-overlap distance tracks
each creature's true radius.
Test: RemoteDeOverlapMechanismTests.ConvergingLargeCreatures_DeOverlapWiderThanHuman
(an R=0.9 pair settles ~1.8 m -- materially wider than the human 0.96 m contact --
proving the sweep de-overlaps at the radius it is given). Register: narrows TS-46
(remotes no longer human-dimmed; residual = the two-scalar reconstruction vs retail's
sphere list, plus the 0.4 m step heights). Core 2621 / App 741 green.

Packed monster remotes interpenetrate in acdream but barely in retail on the same
ACE. Retail de-overlaps them CLIENT-side: it sweeps every remote creature every
tick against neighbours' LIVE resolved positions (the collision shadow == the
resolved m_position, re-registered every moved transition step), with the server
position a gentle catch-up target (CPhysicsObj::MoveOrTeleport 0x00516330), not a
hard-snap. The collision math was already faithful; the bug was the reconciliation
(hard-snap) + the movement model (synth-velocity) + a stale shadow.
A first attempt (reverted) enqueued EVERYTHING and left the shadow at the raw
server position — it gate-failed with invisible monsters (an unplaced body blipped
over a huge distance into the sweep -> garbage pos) and the player stuck on offset
shadows. This redo fixes both root causes, mechanism-proven in a Core test first:
- NPC UpdatePosition routes through MoveOrTeleport with a PLACEMENT-SNAP: the body
is snapped to the server pos when it is not already near it (first UP, no
Sequencer to consume the queue, >96 m, or |Body - worldPos| > 4 m); only near DR
corrections enqueue. This restores the body's placement authority (no invisible
monsters). Airborne keeps the authoritative hard-snap.
- Grounded movement drives the body from the interp CATCH-UP (ComputeOffset ->
InterpolationManager::adjust_offset, REPLACE dichotomy) instead of synth-velocity
(get_state_velocity / SERVERVEL); MovementManager::UseTime runs unconditionally.
- SHADOW-FOLLOWS-RESOLVED: after each tick's sweep the collision shadow is
re-registered at the resolved body (SyncRemoteShadowToBody), movement-gated
(|Body - LastShadowSyncPos| > 1 cm). The per-UP :5669 raw-pos sync is now
PLAYERS-ONLY, so an NPC's shadow is only ever written to its resolved body ->
neighbours de-overlap against resolved bodies, the spread PERSISTS, and collision
== render (no stuck-on-nothing). Landing clears the interp queue.
Preserved: airborne path, sticky #171 (gate + StickyManager overwrite of the seeded
frame), omega, the #173 bounce, landing, the node_fail_counter watchdog, and Path A
(player remotes, untouched -- Slice 2 unifies it).
Tests (RemoteDeOverlapMechanismTests): converging pair settles STABLE at 0.86 m
(barely overlapping = the retail look) WITH the shadow-sync vs <0.40 m (full
overlap) WITHOUT it; a third test drives the REAL InterpolationManager loop and
confirms the sweep absorbs the stall-blip (no pop-into-neighbour). 2-lens Opus
review (CONCERNS) addressed: movement-gated re-flood for the town-FPS risk;
players-only :5669; the blip-absorption test.
Register: retires TS-41 (SERVERVEL synth-velocity -> catch-up), narrows TS-44 (NPC
UP unified onto the interp queue; gate kept for orientation), adds AP-86
(shadow-follows-resolved impl) + AP-87 (MoveOrTeleport 4 m/no-Sequencer placement
snap). Known residual: the de-overlap sweep uses the human sphere for the mover, so
large creatures de-overlap at human radii (TS-46; Slice 3 plumbs Setup dims).
Visual gate PASSED (user: monsters visible + spacing much better). Core 2620 /
App 741 green.

Humanoid creatures/players collide as body Spheres (ShadowShapeBuilder emits
Sphere-type shadows for a Setup with Spheres + no CylSpheres), so player-vs-monster
crowd contact ran through Transition.SphereCollision — a hand-rolled 3-D wall-slide
(register TS-45), NOT a port of retail CSphere::intersects_sphere. It shaved no eps,
force-pushed each contact RADIALLY to a fixed combinedR+1cm shell, ignored the head
sphere, and always returned Slid. In a crowd the opposing radial de-penetration
pushes from neighbours fight each other -> the player wedges and can't wiggle free
(the user's live report).
Port the full CSphere family verbatim — dispatcher 0x00537A80 + step_sphere_up /
slide_sphere / land_on_sphere / collide_with_point / step_sphere_down — the direct
analog of the 2026-07-05 CCylSphere port (#172). The grounded slide now routes
through the shared crease SlideSphere (0x00537440, #116-Ghidra-confirmed) ->

The camera-collision sweep strobed the eye 0.27m every ~5-10 frames while
the compressed chase boom moved along corridor walls (pulledIn 0.27<->0.53
on ~1.4mm input drift): RetailChaseCamera re-demanded the FULL-length ideal
boom from scratch each frame, so the pivot->eye ray re-rolled the same
knife-edge r+-eps graze on the double-faced slabs every frame, and its two
first-contact solutions tear-interleaved at ~1700fps into the #176
"stripes/triangles".
Retail never re-rolls that ray. CameraManager::UpdateCamera (0x00456660)
interpolates FROM THE CURRENT SWEPT VIEWER toward the desired pose
(interpolate_origin/rotation, stiffness 0.45 x dt x 10, clamped) and the
result becomes viewer_sought_position (SmartBox::PlayerPhysicsUpdatedCallback
0x00452d60); update_viewer (0x00453ce0) sweeps pivot->SOUGHT. Pressed against
a wall the sweep ray extends one interpolation step past the contact
(sub-mm at high fps), so a bistable graze can move the eye by at most that
step - the strobe is structurally impossible. A 0.4mm/2e-4 dead-band parks
the sought exactly on the viewer when converged (0x00456fcd-0x00457035).
- RetailChaseCamera: _dampedEye -> _soughtEye + _publishedEye (retail's two
Positions); lerp base = the published (swept) viewer; sweep targets the
sought; total-fallback (ViewerCellId==0) resets the sought like
set_viewer(player_pos, 1). The old "collision must NOT feed back into the
damped state" comment had the coupling backwards - what stays clean is the
transient desired pose, not the sought.
- SweepEye untouched (faithful update_viewer port, exonerated by the #180
investigation).
- Tests: the old pin asserting instant full re-extension after a clamp
(the divergence itself) replaced with four retail pins: gradual
re-extension, sweep-target-converges-onto-contact, total-fallback
re-extends from the player, wall-press glide stability.

The seam-floor purple flicker was NOT a draw z-fight. The in-engine
[seam-*] probe (ACDREAM_PROBE_SEAMDRAW - built because RenderDoc cannot
capture this pipeline: it hides GL_ARB_bindless_texture and the
mandatory-modern startup gate throws; AMD GPU rules out Nsight) killed
every double-draw suspect: ONE shell instance per seam cell at the
lifted z, no floor-coincident entity (portal entities sit at z=-12.05),
zero portal depth fans in the sealed Hub. What it caught instead: the
corridor floor's applied light set flipping wholesale with the flood.
Root cause: c500912b scoped BuildPointLightSnapshot by the per-frame
portal flood, on the research doc's gloss of CEnvCell::visible_cell_table
as "the portal-flood visible set". The named decomp refutes the gloss:
add_visible_cell (0x0052de40) DBObj-LOADS absent cells and inserts them;
a cell activation adds itself + its whole dat visible-cell list
(0x0052e228/0x0052e24a); entries leave only via the flush machinery.
It is the RESIDENT-cell registry - gaze can never remove a cell.
add_dynamic_lights (0x0052d410) walks the WHOLE table per frame
(caller 0x00452d30), and insert_light (0x0054d1b0) caps the pool by
distance to Render::player_pos (0x0054d1dd). Retail's pool is a function
of player position only. Ours followed the camera: turning changed the
flood (probe: 8..41 cells across one turn), the six intensity-100
under-room portal purples entered/left the pool, and the wedge blinked.
Fix: BuildPointLightSnapshot(playerWorldPos) collects ALL registered
(=resident) lit lights; over cap keeps dynamics FIRST (retail's separate
7-slot dynamic pool never competes with statics) then nearest-the-player;
the RebuildScopedLights callback is deleted. Live-verified with the probe:
full-circle turn, flood churning 8..41, the floor set held the same 8
identities on every post-spawn frame. The purple wedge SHAPE stays - it
is cdb-proven retail-faithful.
Residual deviation (AP-85 rewritten): single 128 pool vs retail's
7-dynamic/40-static degrade-scaled dual pools - the Hub now shows
7 purples + viewer where retail's cdb showed 4 + viewer + fixture slots;
if the gate reads the wedge as too purple, the A7 dual-pool cap is the
faithful trim.

Port retail's per-frame light collection: the point-light pool is built from ONLY the
currently-visible cells' lights, matching CObjCell::add_*_to_global_lights
(0x0052b350/0x0052b390) walked over CEnvCell::visible_cell_table (0x0052d410) — not a
flat world-space set capped at 128-nearest-camera.
- LightSource.CellId (retail insert_light arg6 -> RenderLight +0x6c); tagged at both
registration sites from entity.ParentCellId (live weenie fixtures + dat EnvCell statics).
- LightManager.BuildPointLightSnapshot(camPos, visibleCells): a light joins the pool iff
CellId==0 (viewer/global) or its cell is in the flood. 128 cap kept as a now-non-biting
backstop (retail's is 40 static + 7 dynamic, 0x0081ec94/8).
- Threaded via RetailPViewDrawContext.RebuildScopedLights, invoked in DrawInside after the
flood resolves prepareCells and before the draws (renderers select from the same
in-place-rebuilt PointSnapshot; EnvCellRenderer clears its per-cell cache each pass).
- [indoor-light] probe (ACDREAM_PROBE_INDOOR_LIGHT=1) dumps the scoped-pool SET COMPOSITION.
Un-skips LightManagerTests.PointSnapshot_HubScaleLightCount_ObjectSelectionIsCameraInvariant.
CORRECTION: the handoff called the camera-cap the "confirmed" #176/#177 mechanism. The probe
PROVES scoping works (291 Hub fixtures -> pool of 1-9, ~285 through-floor lights dropped/frame,
CellIds match the flood), but the user's VISUAL GATE showed BOTH symptoms unchanged. So pool
composition is NOT the cause. #176 real cause = an over-bright purple point light
(intensity=100, color 0.784,0,0.784 -- from [light-detail]); #177 = a portal-visibility miss
(stairs not drawn looking back). Both stay OPEN. This change is retail-faithful and retires the
camera-eviction latent bug; kept as such, not as the symptom fix. Register AP-85 corrected;
ISSUES #176/#177 re-diagnosed; render digest banner updated.

The MaxGlobalLights 128->1024 fix (4d25e04d) was live-tested and made
the eviction pops stop — but with the full 366-fixture pool active,
three unported retail lighting semantics dominate the Facility Hub:
(a) lights reach THROUGH solid floors/walls: retail registers lights
per-CELL (insert_light 0x0054d1b0) so the under-room portals'
purple light never touches the corridor above; our flat
sphere-overlap selection has no reach/occlusion notion — rooms
washed magenta (user screenshot).
(b) stationary weenie fixtures ride the DYNAMIC 1/d falloff (~9x
retail's static 1/d3 bake curve at 3m) — the #143 isDynamic
assignment is wrong for ACE-served world fixtures.
(c) an unexplained striped z-fight-like artifact on lit floor regions
(user screenshot; no coincident dat geometry — the coplanar-pair
sweep came back empty; not a striped texture — all corridor
surfaces are plain Base1Image stone).
Reverted to 128. The cap is now documented as a LOAD-BEARING STOPGAP:
it accidentally approximates per-cell reach by keeping the pool local
to the camera. The #176/#177 root cause (cap eviction popping per-cell
light sets) stays CONFIRMED and fully documented; the real fix is the
A7 dungeon-lighting arc: per-cell light registration + the static
fixture curve + the stripe hunt, THEN uncap. The desired-end-state pin
is kept as Skip with the full pointer. Register row AP-85 rewritten to
match reality; ISSUES #176/#177 back to OPEN with the complete
mechanism story.

The probe launch discriminated it: the user reproduced the purple floor
flash while [light] (ambient branch) and [pv-input] (portal flood) read
provably healthy — eliminating the last CPU-side theories and exposing
the one channel the probes could not see: per-cell 8-light set
composition.
BuildPointLightSnapshot kept the MaxGlobalLights=128 point lights
nearest THE CAMERA; the Facility Hub registers 366 fixtures, so 238
were evicted per frame by camera distance. SelectForObject (faithfully
camera-independent, and unit-pinned as such) could only choose from the
surviving 128 — an in-range torch of a visible cell that ranked past
the cap dropped out of that cell's 8-set, so per-cell Gouraud lighting
flipped as the chase boom swung the camera:
- #176: the flipping unit is a CELL -> discontinuity lines at exactly

The 'run into the last corridor window and pop up through its roof'
report: the live callers passed sphereHeight: 1.2f into
SpherePath.InitPath, whose head-sphere formula (height - radius) put the
head sphere center at 0.72 - the capsule top at 1.2m. The top 0.63m of a
1.83m character had NO collision, so at the corridor-end window alcove
(0x8A020179 -> 0x8A02017E: 0.70m sill face, 1.3m opening, sloped funnel
behind) the step-up's placement never saw the head overlapping the
lintel solids and let the player climb in head-through-roof.

spheres = (0,0,0.475) r=0.48 and (0,0,1.350) r=0.48 - capsule top 1.83 =

The Facility Hub corridor dead-stop's second half: after one seam hit,
every forward resolve returned ok=False hit=no with zero advance. The
body-persisted SlidingNormal (-1,0,0) projected the exactly-anti-parallel
corridor push to zero in AdjustOffset and the step loop aborted at step 0
before any collision test could refresh the state.
Audit (docs/research/2026-07-06-137-sliding-normal-lifecycle-audit.md):
retail's only in-transition sliding-normal writer is validate_transition
(0x0050ac21); the whole sphere/BSP layer writes NONE (grep-verified), and
the body persistence (SetPositionInternal 0x005154c2, SLIDING_TS bit sync
0x005154e1) runs only on transition success. Our BSPQuery Contact-branch
full-hit responses were stubs (SetCollisionNormal + SetSlidingNormal +
return Slid) where retail dispatches the real slide_sphere — so the seam
hit (a SUCCESSFUL full-advance resolve per the live log) persisted the
phantom wall's normal, which retail's lifecycle structurally cannot do.
- BSPQuery Contact foot full-hit fallback + head full-hit now route
through Transition.SlideSphereInternal (CSphere::slide_sphere
0x00537440 — in-frame slide, no sliding-normal write; ACE
BSPTree.cs:202,310-316). The dead stub is rewritten as the faithful
BSPTREE::slide_sphere wrapper.
- PhysicsEngine sliding writeback gated on ok (retail success-only
placement; behaviorally latent, removes the failed-frame leak class).
- Register: TS-4 amended (Path-6 steep-tangent sites still write the
normal — now documented), TS-45 added (SphereCollision's write — same
leak class, left for a follow-up out of #171's blast radius).
- Pins: Issue137SlidingNormalLifecycleTests — both site pins RED->GREEN,
plus the retail persist/absorb/clear wall lifecycle (validate-write
persistence, faithful absorbed anti-parallel frame, oblique escape
clears the bit). BSPQueryTests full-hit pin updated to the real slide.
Mechanism 1 (PortalSide portal polys solid in the physics set) stays

The Facility Hub double door (Setup 0x02000C9D) embeds the player into
the visual panel from one side and blocks with a phantom slab on the
other: its Setup PLACEMENT frames pose the two panels AJAR (yaw
-150/-30 deg, 0.44 m behind the doorway plane — dat-confirmed by the
Issue175 inspection) while the rendered door poses them CLOSED from
the wire-supplied motion table via the sequencer. ShadowShapeBuilder
read placement frames, so the 1.66x0.29x2.95 m physics slabs
registered at the ajar pose. Retail tests each part's LIVE
CPhysicsPart pose — for an idle door, the motion table's default
(closed) state.
Fix: ShadowShapeBuilder.FromSetup gains partPoseOverride (BSP part
shapes only); RegisterServerEntityCollision derives it from the spawn
MotionTableId via GameWindow.MotionTableDefaultPose (default style ->
first cycle -> LowFrame part frames). Null/short poses fall back
per-part to placement frames — table-less entities and landblock
statics unchanged. One-shot snapshot vs retail's per-frame live pose
is register row AP-84 (equivalent for the door lifecycle: closed ==
default pose; open == ETHEREAL bypasses collision, #150).

An observed character jumping into a dungeon ceiling hovered at the
roof until its ballistic arc decayed, landing visibly late (user
report, 0x0007). The remote DR tick sweeps collision (position pinned
at the ceiling — no clip-through) but retail's post-transition velocity
response, CPhysicsObj::handle_all_collisions (pc:282699-282715:
v -= (1+elasticity)*dot(v,n)*n), was only ported for the LOCAL player
(L.3a). The remote body kept its +Z launch velocity and re-integrated
it into the roof every tick — the position was clamped but the
timeline was pure ballistics.
Retail runs handle_all_collisions after every SetPositionInternal for
every physics object, remotes included. Mirror the local reflection
block in the remote sweep's post-resolve path: same formula, same
AD-25 airborne-before-AND-after suppression (corridor slides and
landings don't reflect; the landing snap's Velocity.Z <= 0 gate stays
intact), same Inelastic zero-out for future missiles. AD-25 register
row extended to cover both sites.

The Holtburg town-network portal platform (stab 0xC0A9B465, Setup
0x020019E3, CylSphere r=2.597m h=0.256m) blocked the player with an
endless rim slide instead of retail's step-up-onto-top — gating the
whole #137 dungeon repro. Surfaced when #149 started registering
BSP-less stab CylSpheres: the collision SHAPE became right while the
RESPONSE was still the hand-rolled AP-6 approximation (step-up gate +
radial wall-slide only).
Root cause: no cylinder-TOP support anywhere. DoStepUp's internal
step-down probe needs retail's step_sphere_down (0x0053a9b0) to land on
the flat top — a cylinder has no polygons for the walkable search — so
every step-up onto a wide cylinder failed into StepUpSlide and the
player orbited the rim (probe-confirmed: [cyl-test] result=Slid with
horizontal rim normals, launch-137-repro.log).

Structural capstone of the R5 movement-manager arc; zero behavior change.
Retail MovementManager (acclient.h /* 3463 */, 16 bytes / four pointers)
gives every CPhysicsObj ONE owner for its motion_interpreter +
moveto_manager. acdream carried them as loose per-entity objects wired by
hand at three sites. This slice:
- New src/AcDream.Core/Physics/Motion/MovementManager.cs — owns
MotionInterpreter + lazy MoveToManager (MakeMoveToManager 0x00524000 via
a MoveToFactory closure, the acdream stand-in for the physics_obj/
weenie_obj backpointers) + the relays with retail call shapes:
PerformMovement 0x005240d0 (types 1-5 -> minterp, 6-9 ->
MakeMoveToManager + moveto, (type-1)>8 -> 0x47), UseTime 0x005242f0
(moveto only), HitGround 0x00524300 (minterp FIRST then moveto),
HandleExitWorld 0x00524350 (minterp only), CancelMoveTo 0x005241b0,
HandleUpdateTarget 0x00524790, IsMovingTo 0x00524260.
- RemoteMotion.Movement + PlayerMovementController.Movement hold the ONE
facade; Motion/MoveTo become child views so the comment-dense call sites
read unchanged. The three wiring sites (EnsureRemoteMotionBindings,
EnterPlayerModeNow, the chase harness — same commit per the mirror rule)
construct through MoveToFactory + MakeMoveToManager(), preserving the
pre-facade eager timing (side-effect-free ctor = unobservable either way).
- Relay call sites repointed: both remote landing HitGround pairs + the
player landing pair, despawn HandleExitWorld, TickRemoteMoveTo + the
player Update UseTime, RouteServerMoveTo (takes the facade; routes via
the retail PerformMovement dispatch), InstallSpeculativeTurnToTarget,
host HandleUpdateTarget/InterruptCurrentMovement closures (retail
CPhysicsObj::HandleUpdateTarget @0x00512bf0 fan head + the TS-36
interrupt chain, now the literal facade relays).
- NOT absorbed per the slice spec: unpack_movement stays App
(RouteServerMoveTo + UM heads; Core.Net types stay out of Core.Physics);
TS-42 per-tick order untouched (R6); #170/#171 gate-passed machinery
untouched. PerformMovement's set_active(1) head not re-asserted (spawn
asserts Active; status quo — no new register row).
- Register: TS-41/TS-42 source wording freshened to the facade shape;
AD-36 retire note corrected (facade half closed; residue = entities
that never get a RemoteMotion). No new rows.
- Conformance: 15 new MovementManagerTests pin the dispatch table, lazy
create, relay targets/order, null tolerance. Suite 4052 green; the
183-case/funnel/moveto/chase/sticky suites UNMODIFIED (harness
construction mirrors production, test bodies untouched).

Gate 2: pack behavior good except "sometimes the monster is in the
character / too close vs retail". The ACDREAM_PROBE_STICKY capture
nailed it frame-by-frame: 1661 deep-overlap AdjustOffset ticks, ALL
steering inward (dist -0.65 -> -0.78 -> ... -> -1.9 at +0.13/tick),
monsters converging to centerDist~0 — while the suppressed-snap lines
show ACE's authoritative positions stayed properly OUTSIDE (drift up to
7.7 m). The radii were correct (tgtR=0.68, ownR=0.59-0.98).
Root cause: ACE's literal decode of StickyManager::adjust_offset
(`if (delta >= |dist|) delta = dist;`) leaves delta POSITIVE when the
overlap exceeds one tick's step — steering TOWARD the target center, a
runaway whose equilibrium is centers-coincident. ACE servers virtually
never reach that branch (quantum >=1/30 -> threshold ~1 m); at
render-rate quanta the threshold is ~0.13 m and pack jostle trips it
constantly. The BN mush (0x00555554-0x00555597) is unreadable on
exactly this compare; the retail oracle (side-by-side on the same ACE:
monsters separate) refutes the ACE-literal reading.
Pin: sign-correct clamp — `else if (dist < 0) delta = -delta` (back off
rate-limited). Identical to ACE-literal in every shallow/outside case.

Gate 1 (2026-07-04): "better in general" + three residuals — monsters
pushed INTO the player, attacks with stale facing, position
"flashing/flapping instead of gliding". All three are ONE mechanism:
the legacy NPC UpdatePosition handler hard-snaps position, orientation,
and velocity/cycle UNCONDITIONALLY, fighting the armed sticky every UP
(ACE's authoritative rest pose sits ~0.6 m out and its server-side
facing lags the strafing target; the client stick holds 0.3 m + live
facing — oscillation at UP cadence).
Retail is immune by architecture, not by tuning: UP corrections flow
through the InterpolationManager into the SAME per-tick
PositionManager::adjust_offset chain where StickyManager::adjust_offset
OVERWRITES them while armed (0x00555190 chain order; 0x00555430 assigns
m_fOrigin). A server correction can never fight an armed stick
frame-by-frame. The remote-player branch already has exactly that
(queue -> combiner -> sticky overwrite); the legacy NPC path snaps
outside the chain.
Fix: suppress the NPC UP position/orientation/velocity-adoption snaps
while the entity is stuck (PositionManager.GetStickyObjectId() != 0) —
the retail chain semantics translated to the snap architecture.
LastServerPos/Time + cell bookkeeping still record; server truth
reasserts on the first UP after unstick, bounded by the 1 s sticky
lease. Register row TS-44 (same commit); retires with the S6/R6
interp-queue unification of the NPC path.
Apparatus: ACDREAM_PROBE_STICKY=1 — per-guid [sticky] lifecycle lines
(STICK / UNSTICK / LEASE-EXPIRE / TARGET-status teardown), per-armed-
tick steer lines (signed gap dist, applied delta, heading delta, live
resolve), and [sticky-snap-skip] at the suppressed-snap site.
PhysicsDiagnostics.ProbeStickyEnabled owns the flag (rule #5).

Group-melee interpenetration + facing drift: the R5-V1-ported
StickyManager/PositionManager were Core-only — the StickTo/Unstick seams
were unbound and every arrival radius was 0, so ACE's Sticky|UseSpheres
melee chases closed ~one body-radius too deep and froze at stale arrival
poses until the next wire re-arm. Retires TS-39.
Wiring (anchors re-verified against the named decomp this session):
- EntityPhysicsHost owns a PositionManager; HandleUpdateTarget fans
MoveToManager then PositionManager (CPhysicsObj::HandleUpdateTarget
0x00512bc0 order).
- Seams bound remote + player: MoveToManager.StickTo (BeginNextNode
sticky arrival @0x00529d3a), Unstick (PerformMovement head), and
MotionInterpreter.UnstickFromObject (UM funnel head, 0x0050eaea).
- AdjustOffset at the retail UpdatePositionInternal slot (@0x00512d0e):
NPC branch composes pre-sweep (steer is swept by ResolveWithTransition);
remote-player branch chains the combiner offset through the shared
delta frame (the interp stage) so sticky OVERWRITES when armed
(0x00555430 assigns m_fOrigin, not accumulates); player inside the
30 Hz physics quantum before UpdatePhysicsInternal.
- UseTime (the 1 s lease watchdog) at the UpdateObjectInternal tail
(@0x005159b3): unconditional per remote; player gated on the physics
tick (retail's MinQuantum gate skips UseTime too).
- Real setup cylsphere radii (CPartArray::GetRadius/GetHeight
0x005180a0/0x005180b0 = setup radius/height x ObjScale from the spawn
record): own via EnsureRemoteMotionBindings + player wiring; target via
RouteServerMoveTo AND the speculative use-walk install (retail resolves
the target PartArray at EVERY MoveToObject site — ACE PhysicsObj.cs:951).
- Teardown parity: exit_world (0x00514e60) UnStick + ClearTarget before
the ExitWorld notify; player teleport fires teleport_hook's tail
(UnStick in SetPosition + EntityPhysicsHost.NotifyTeleported =
ClearTarget + NotifyVoyeurOfEvent(Teleported) @0x00514f1b) so mobs
stuck to the player drop their sticks on a recall.
- SERVERVEL arbitration also yields to a stuck entity (same starvation
class as the #170 fix — sticky owns the between-snap translation).
- StickyManager.UseTime aligned to retail's strict > deadline
(0x00555626; ACE >): two V1 tests had pinned the >= edge — corrected.
Register: TS-39 deleted; TS-41 narrowed (stickyArmed gate); TS-43 added
(remote teleport_hook gap — self-corrects within the 1 s lease); AP-23
narrowed (real radii at the speculative site; only the use-radius
buckets remain invented).

RemoteChaseEndToEndHarnessTests (arrive -> stick -> strafing-target
gap+facing track -> lease expiry; unstick-on-rearm -> re-stick).

confirmed and fixed 4 findings: ObjScale-dead radius read, player
UseTime order inversion, missing teleport voyeur notify, speculative-
site radius asymmetry.

The "sustain the run" residual. The handoff's "Ready stop-node backlog
drains a beat slower than retail" framing was DISPROVEN: a new full-stack
offline harness (RemoteChaseEndToEndHarnessTests — real MoveToManager +
MotionInterpreter + AnimationSequencer + MotionTableDispatchSink + the
manual omega integration, wired field-for-field like
EnsureRemoteMotionBindings and ticked in TickAnimations' exact phase
order) proves the Core turn/run/drain pipeline healthy: the chase turn
completes in <1 s both directions, BeginMoveForward installs per arm, the
run sustains across re-arms and attack swings, and pending_motions fully
empties (retail cdb invariant add_to_queue == MotionDone).
The real mechanism (launch-drainq.log, corrected per-guid attribution —
the previous session's timeline mis-attributed [mvto] lines that fire in
the network phase): funnel per chasing scamp was 16 mt-6 arms -> 11
dispatched turns -> ONE BeginMoveForward. Any NPC receiving
UpdatePositions gets HasServerVelocity=true (synthesized from position
deltas even when the wire carries no velocity), and the grounded per-tick
branch routed those to the SERVERVEL leg, which SKIPS
MoveToManager.UseTime — [npc-tick] literally logged
"branch=SERVERVEL (skips UseTime) mtState=MoveToObject". The armed
moveto was starved for exactly the duration of the server-side chase:
legs stayed in Ready while the body glided on synthesized velocity (the
#170 slide); the manager only woke in UP-silent gaps (creature stopped
server-side) and its stale-heading turn was interrupted by the next UM
before reaching BeginMoveForward.
Retail runs MovementManager::UseTime UNCONDITIONALLY every tick
(CPhysicsObj::UpdateObjectInternal 0x005156b0, call @0x00515998) and has
no wire-velocity leg-driver anywhere; between UPs a moveto-driven body
translates from the motion state (get_state_velocity) with UP hard-snaps
correcting drift. Fix: an armed moveto (MovementTypeState != Invalid)
always takes the MOVETO leg; SERVERVEL remains only as the legacy
fallback for entities without a moveto (scripted paths / missiles).
Register: TS-41 (the narrowed SERVERVEL stopgap), TS-42 (drain-order
divergence also pinned this session: acdream drains AnimDone->MotionDone
AFTER HandleTargetting/MoveTo.UseTime; retail's process_hooks
@0x00512d3d runs BEFORE TargetManager/MovementManager in
UpdateObjectInternal — one frame of extra latency, R6 scope).
New conformance: RemoteChaseEndToEndHarnessTests (3 scenarios + theory)

demonstrated the TS-40 InWorld=false link-strip wedge shape — harness

Replace the AP-79 P4 TargetTracker poll adapter with the ported retail
TargetManager voyeur subscription system, wired per entity. Behaviorally a
faithful no-op refactor for the common cases (server-directed creature chase
+ auto-walk-to-object), now driven by the retail mechanism instead of the
GameWindow poll.
New: EntityPhysicsHost (App) — the per-entity IPhysicsObjHost (retail
CPhysicsObj stand-in), owning a TargetManager. Delegate-injected accessors so
it stays free of GameWindow internals (code-structure rule #1).
Wiring (GameWindow):
- _physicsHosts registry (guid → host) = retail CObjectMaint::GetObjectA,
backing the voyeur round-trip's cross-entity delivery.
- ResolvePhysicsHost lazily creates a minimal position-only host for ANY known
entity — retail lets every CPhysicsObj host a target_manager, so a STATIC
object (chest/corpse) still answers add_voyeur; without this, auto-walk to a
never-animated object would arm the moveto but never receive the immediate
target snapshot and never start.
- MoveToManager set_target/clear_target/quantum seams repointed at the host's
TargetManager (remote + player).
- HandleTargetting ticked unconditionally per entity BEFORE UseTime (retail
UpdateObjectInternal order): per-remote loop for remotes, pre-Update block for
the player. The player's tick is load-bearing for creature-chase — the player
as a watched target pushes its position to the chasing NPCs' HandleUpdateTarget
each frame, ahead of their UseTime.
- Despawn (RemoveLiveEntityByServerGuid): NotifyVoyeurOfEvent(ExitWorld) to the
entity's watchers before pruning the host — the only cleanup for a watcher
whose target already sent an Ok (past Undefined, the 10s staleness never fires).
Deleted: RemoteMotion.TrackedTarget* fields + _playerMoveToTarget* GameWindow
fields + the two manual poll blocks. AP-79 register row retired same commit
(AP section 73→72).
Delivery is now synchronous-on-set_target (retail: set_target is last in
MoveToObject, so the immediate snapshot lands with all moveto state in place)
vs AP-79's next-frame poll — more faithful. Full suite 4006 green.

Retail's apply_interpreted_movement (0x00528600) does NOT dispatch with
ctor-default MovementParameters: the BN decomp smears the bitfield store
into the mush expression at raw 305778 - (word & 0x37ff) | cancelMoveTo<<15
| disableJump<<17 - which CLEARS SetHoldKey/ModifyInterpretedState/
CancelMoveTo. ACE MotionInterp.cs:444-449 confirms independently. Three
legs fixed, all retail decode, no adaptations added:
1. ApplyInterpretedMovement now builds the pass params retail actually
uses (ModifyInterpretedState=false is load-bearing): no dispatch in the
pass writes InterpretedState, so the airborne Falling substitution
PRESERVES the wire's forward command and HitGround's re-apply
dispatches it - the motion table plays the Falling->X landing link.
The W6 entry-cache (built on the wrong "retail self-heals via hoisted
registers" theory) is deleted; live reads are retail semantics. Raw
arg3 decoded as DisableJumpDuringLink -> every (N,0) caller means
allowJump=true; all 9 caller polarities fixed. copy_movement_from's
current_style copy (raw 0051e757) added to the UM flat-copy.
2. Both GameWindow landing blocks cleared the Gravity state bit BEFORE
Motion.HitGround(), whose verbatim state&0x400 gate then no-opped the
whole retail re-apply; the UP-driven landing block never called
HitGround at all. Both now run HitGround (minterp then moveto,
MovementManager::HitGround 0x00524300 order) with Gravity still set,
then do the DR bookkeeping clear (register row AP-81 added for the
remaining flag dance, retire in R6).
3. K-fix17's forced SetCycle (both copies) deleted: it executed every
landing but read the leg-1-clobbered ForwardCommand (0x40000015) and
re-set the very Falling cycle it meant to clear.
Tests: new HitGround_AfterFall_RedispatchesPreservedForward_ExitsFalling
lifecycle pin; AirborneBody state assertion flipped (it had pinned the
bug value). Suite 3,964 green incl. the 183-case retail-observer trace.
Filed #164 (action-replay Autonomous bit, no current consumer).

zero wire input.

Root cause (pinned by the worktree investigation + verified against
source): CMotionInterp's dispatch tails strip link animations for
DETACHED objects only (retail `if (physics_obj->cell == 0)
RemoveLinkAnimations`, raw @305627, three ported sites:
DoInterpretedMotion / StopInterpretedMotion / StopCompletely). The R3
port proxied retail's cell pointer with CellPosition.ObjCellId == 0 -
but that #145 field is seeded ONLY by SnapToCell, whose single
production caller is the LOCAL PLAYER's SetPosition. Every REMOTE body
therefore read "detached" forever, and every dispatch stripped the
transition link the motion table had just appended: a used door's
swing link died the same tick (pose snapped closed<->open - the live
symptom), and remote walk<->run link poses have been silently eaten
since the guard landed (masked: locomotion cycles resemble each other;
a door's two poses don't). The dispatcher itself (GetObjectSequence
link path) was verified retail-verbatim end-to-end - not the bug.
Fix: PhysicsBody.InWorld - an explicit "placed in the world" flag
carrying exactly the guard's retail meaning (register row TS-40,
replacing the previously UNREGISTERED ObjCellId proxy). Set by
SnapToCell (retail: enter_world/set_cell assigns the cell) and by
RemoteMotion construction (a RemoteMotion exists only for a world
entity). All three guard sites now test !InWorld. Default false =
retail's pre-enter_world detached state, preserving the guard for
genuinely unplaced bodies (bare-harness interps unchanged).
Tests: InWorldLinkGuardTests pins the polarity at all guard classes
(in-world dispatch keeps links; detached strips; StopCompletely same).
Full suite green: 3,961.
If the door still snaps after this, the open question is DATA (does
the door's table author an On<->Off link at all) - next step per the
investigation: dump the real table's Links/StyleDefaults via a
DoorSetupGfxObjInspectionTests extension.
