Investigation handoff for the deferred A7 per-cell light-scoping fix (#79/#93/#176/#177).
Ambient verified retail-faithful three ways (decomp + dat SeenOutside + live retail
cdb capture: SetWorldAmbientLight level 0x3e4ccccd == 0.2f bit-exact). No fix applied.

The live retail cdb trace decided it: retail roots at the connector 0118 at the
grey pose (NOT the PICK fork) AND still draws the player room 0116 from that root,
because retail's InitCell side test reads the dat PortalSide bit where acdream's
render path reconstructed the interior side from the cell AABB centroid (mis-sides
a thin connector). ISSUES #186 -> CLOSED; handoff gets a RESOLVED banner.

Retail SEAMLESS at the same spot (user-confirmed) => real acdream bug: the eye seats
in a sparse 5-poly connector cell 0xF6820118 looking back at the player's room 0116,
and acdream drops 0116 (back-portal side-culled) so the doorway aperture shows the fog
clear color = grey; retail keeps 0116 drawn. RULED OUT: null-root/AD-20/AD-21 (root
valid, eyeInRoot=Y); the color-clear gating (retail's gated DrawCells Clear is
depth/stencil, post-LScape::draw). Next step = retail cdb trace (viewer_cell +
cell_draw_list at the grey pose) to pin viewer-cell PICK vs portal FLOOD, then a careful
frozen-render fix. Full handoff + apparatus + DO-NOT-RETRY + code/decomp sites in the doc.
Keeps the offline cell-geometry inspection test.

Slice 2 (2a e1ac56cc extract + 2b ddb5a967 fork-collapse) shipped and the visual
gate PASSED (user: "Looks good"), closing #184. Mark ISSUES #184 DONE and the Slice 2
handoff DONE, both noting the review-driven correction: non-PK players WALK THROUGH
each other (retail PvP), so the player win is monster/terrain/wall collision, not
player-vs-player de-overlap.

Deliberately deferring the last #184 piece (Slice 2) to a fresh focused session per
the user's call. This is a self-contained handoff: the #40 sweep-blip verdict (DEAD,
high confidence — Path B already runs that config stably + a Core test proves it),
the 2a-first-then-2b plan, the exact code sites (Path A :10194-10429, Path B, the
extraction seam :10152-10873, the shared-helper wrinkle), the 2b merge gotchas
(Path A's player-specific omega/compose/diagnostic bits; the coupled :5699 shadow
sync), the preserve-list, and the test/gate plan.
Corrects the earlier ISSUES characterization: Slice 2 is a GATED behavior change to
the frozen R4/R5 arc (players gain the sweep), not a no-gate refactor. The #184
symptom itself stays RESOLVED + gated (Slices 1+3).

The crowd-tightness residual from the #182 gate: monsters overlap (arms) in acdream but
barely in retail on the SAME ACE. Verified root (workflow wf_d2ff782f-9cb + source): retail
runs UpdateObjectInternal+transition on EVERY remote creature (CPhysics::UseTime 0x00509950,
no fork) so they de-overlap client-side, with the server pos a gentle MoveOrTeleport catch-up
target (0x00516330), NOT a hard-snap. acdream (a) hard-snaps NPC remotes to the raw overlapping
server pos (GameWindow.cs:5925) overwriting the swept de-penetration, and (b) forks player-remotes
(skip sweep) from NPCs (sweep at :10558 but driven by get_state_velocity, not the catch-up).
Collision math already exists + is faithful; the fix is the reconciliation (hard-snap→catch-up)
+ the movement model (synth-velocity→interp catch-up) — a delicate rework of the frozen R4/R5
remote-DR arc, staged NPC-first. Design spec + full handoff (verified code sites, retail anchors,
preserve-list, gotchas, slices) written for a fresh session. Implementation NOT started.

Humanoid creatures/players collide as body Spheres (ShadowShapeBuilder emits

force-pushed each contact RADIALLY to a fixed combinedR+1cm shell, ignored the head

VSync-on test (30fps): stripes remain => not tearing (windowed + DWM never tears - the tear framing was structurally wrong). Clean captures at the user's spot: the scene is pixel-static except idle anim; the 'stripes/triangles' are the corridor wall's angled braces silhouetted against blown-out saturated magenta. Server-weenie stationary lamps register isDynamic:true (1/d, range x1.5); retail statics use f=(1-d/range)*intensity*wrap/d^3 beyond 1m, range=falloff*1.3, per-channel colour clamp - ~10x dimmer at 3m.

The user's retail axiom (camera rock steady pressed into walls) vs our measured wall-press wander (~0.5mm/frame limit cycle, headless pin Issue181WallPressEquilibriumTests) sent us back to the decomp. Ghidra (clean, vs the BN x87 mush): retail VIEWERS subdivide the sweep into EXACTLY radius-length steps anchored at the start (offsetPerStep = offset*r/len, numSteps = floor(len/r)+1) with the final step recomputed mid-loop as the exact remainder (find_transitional_position 0x0050bdf0), and the negligible-offset abort is NON-viewer-only. Ours used ceil equal-slices for everything and aborted viewers too. Ported faithfully (pseudocode docs/research/2026-07-06-viewer-step-subdivision-pseudocode.md); non-viewer stepping already matched (TRANSITIONAL_PERCENT_OF_RADIUS=1.0).
Measurement: the wall-press limit cycle is UNCHANGED by the port (537.8um avg; a bit-exact 12-frame cycle: ~130um/frame inward creep x11 then a 2.6mm snap). With adjust_to_plane + adjust_sphere_to_poly now also Ghidra-verified faithful, the residual mm cycle is likely retail-class plateau physics - invisible at retail's 60fps vsync, tear-interleaved into visible stripes at our ~1500fps unsynced. The decisive user test: VSync ON (Settings/F11). Fallback discriminator: cdb-trace retail's viewer at a wall press. Suites green (Core 2600 / App 733 / UI 425 / Net 385).

The autonomous visual loop on the stateful-sought camera exposed the true
root of the #176 stripes: a ~19Hz SAWTOOTH. The sought re-extends ~3mm/frame
and the sweep silently passes while the 0.3m viewer sphere presses up to
~0.25m past the wall plane, then clips a whole transition step (~0.27m) back.
Headless replay against the real Facility Hub corridor BSP (0x8A020164, the
captured ray) reproduced it exactly: pre-fix, embedded targets passed
unclipped and the first detection stopped at the PREVIOUS STEP BOUNDARY,
tracking the target (eyeBack = s - 0.27).
Root cause: BSPQuery.AdjustToPlane - copied from ACE's BSPTree.cs port -
was structurally inverted and ALWAYS returned false (the touchTime==1 branch
re-placed the sphere at the unchanged check position; touchTime<1 iterated
doing nothing; the <0.02 convergence exit returned false). With the
PerfectClip exact-contact machinery dead, CollideWithPt always fell to the
bare Collided path and the transition reverted the colliding step whole.
ACE never noticed: PERFECT_CLIP (0x40) is a client camera flag the server
never exercises (feedback_bn_decomp_field_names class 3 - the retail binary
outranks ACE in branches ACE never runs). The pre-stateful camera flipped
1-step vs 2-step backoffs on mm drift - the measured pulledIn 0.27 <-> 0.53
of the original #176 strobe was step quantization all along.
Rewritten per the retail binary (pseudocode doc
docs/research/2026-07-06-adjust-to-plane-pseudocode.md):
- BSPTREE::adjust_to_plane (0x00539bf0): clearTime/hitTime bounds (0.0/1.0),
Phase 1 walks plane-touch times re-testing the whole tree (the tree test
feeds a DIFFERENT blocking poly back into the next iteration), Phase 2
binary-searches with the SHARED iteration counter, window < 0.02 =
CONVERGED, final commit = last known-clear time. Only failure = Phase-1
exhaustion.
- CPolygon::adjust_sphere_to_poly (0x00538170): early-out = plane-band test
at the START position (was: precise-poly test at the check position);
touch side = sign(dpPos)*radius (was: hard-coded -radius; ACE misdecoded
it as movement.LengthSquared() <= r^2); result unclamped per retail.
Replay pin Issue180CorridorSweepHysteresisReplayTests: short-of-touch
targets pass, past-touch targets always clip, and the clipped stop is the
CONSTANT surface-contact point (eyeBack 1.609 across the band; spread
< 0.03m) instead of tracking the target.
Suites green (Core 2600+2skip / App 729+2skip / UI 425 / Net 385).

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.
- Pseudocode doc: docs/research/2026-07-06-camera-sought-position-pseudocode.md
(UpdateCamera tail incl. the sought derivation + set_viewer reset semantics
+ Frame interpolate/close_rotation).
- Register: AD-37 (forward-vector nlerp vs quaternion slerp), AD-38

pre-existing, identified during the decomp reading.
Suites green (Core 2599+2skip / App 729+2skip / UI 425 / Net 385).

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.
Pins: PointSnapshot_HubScaleLightCount_ObjectSelectionIsCameraInvariant
(rewritten to the corrected model),
PointSnapshot_OverCap_DynamicsNeverEvictedByNearerStatics,
PointSnapshot_OverCap_KeepsNearestThePlayer,
PointSnapshot_ResidentCollection_CellTagDoesNotFilter.
Suites: Core 2599+2skip / App 726+2skip / UI 425 / Net 385.
The [seam-*] probes stay until the visual gate passes, then strip.

cdb trace of LIVE retail (tools/cdb/issue176-floor-light.cdb, binary<->PDB MATCH) PROVED retail
applies ALL its dynamic lights — 4 intensity-100 magenta portal lights (d3dIdx 3-6, falloff 6) +
the viewer fill (d3dIdx 1, 2.25) — as D3D hardware lights to EVERY Facility Hub cell, every frame,
stable. So the faceted purple wedges on the floor are retail-FAITHFUL. acdream did a per-cell
SelectForObject sphere-overlap 8-cap for cells, so the portal set could differ/flip per cell.
- LightManager.SelectForCell (retail minimize_envcell_lighting 0x0054c170): ALL dynamic lights
applied unconditionally (shader range cutoff zeroes non-reaching = D3D hardware range), then
nearest static torches fill remaining slots. Wired into EnvCellRenderer.GetCellLightSet.
Objects keep SelectForObject (minimize_object_lighting). Pins:
SelectForCell_AppliesAllDynamicLights_EvenOutOfReach + _SameDynamicSet_ForCellsFarApart_NoFlap.
- Apparatus: [light-detail] gains owner/cell/dyn (pinned the culprit = 2 portal weenies
0x000F4247/48 in 0x8A020118/19, intensity=100 magenta); CellVertexNormals_SmoothOrFaceted_Dump
(corridor floor uses SMOOTH per-vertex dat normals, not flat); tools/cdb/issue176-floor-light.cdb.
#176 RESIDUAL is NOT this fix. It's a RUNTIME draw z-fight in the seam floor. Eliminated (evidence):
NOT lighting (per-light cap + this both no-change), NOT membership (render cell 0x8A020164 stable
100% of 188k frames / 526 angles, res=None), NOT dat geometry (coplanar sweep empty at z=-6 floor

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.

Session handoff for the next pickup. #176 (purple seam flash) + #177

MaxGlobalLights=128 snapshot cap evicting in-range lights of visible

unported per-cell light-reach (through-floor light) + the fixture

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
cell-seam granularity; a torch-losing floor drops to dim blue-grey
stone at 0.2 ambient (the perceived purple), camera-angle dependent.
- #177: a stair room whose torches all ranked past the cap rendered at
bare 0.2 ambient (near-black = 'not visible'); approach re-admitted
them ('pops into existence'); the sweeping boundary dropped the
ramp's lights mid-descent ('disappears on the last step'). The
geometry never vanished - its lights did.
Retail's minimize_object_lighting (0x0054d480) has NO global
camera-nearest pool cap (lights register per cell, insert_light
0x0054d1b0). Fix: MaxGlobalLights 128 -> 1024, a non-biting safety
valve (GlobalLightPacker grows to fit; 64 B/light). Register row AP-85.
TDD pin: PointSnapshot_HubScaleLightCount_ObjectSelectionIsCameraInvariant

The dungeon render pair (purple seam flash + stair pop-in) resisted
desk root-causing, but the investigation narrowed the space to two
live theories and shipped permanent apparatus:
- Issue176177DungeonSeamInspectionTests: dat truth — corridor floors
ARE textured drawn PortalSide portal polys; the reciprocal is NoPos;
the 'stairs' are 0x8A020182's ramp shell (vertical portals, zero
statics); CellBSP partitions exactly at portal planes; DXT1 textures
carry zero transparent-mode texels.
- Issue176177FacilityHubFloodReplayTests: production-matched flood
replays — approach/descent/gaze-sweep/walk all healthy with coherent
inputs; ScenarioE pins the flood's collapse-to-root sensitivity under
incoherent (root, eye) pairs.
- Issue176177SeamTransitLagTests: the resolver flips cells within one
tick-step of the portal plane — the 0.33-0.47m [cell-transit] 'lag'
in the gate logs is speed*tick quantization, not membership error.
Refuted (do NOT retry — ledger in the research doc): placeholder
texture, reciprocal z-fight, seal z-fight (seals only fire for
OtherCellId==0xFFFF), root/eye incoherence (production camera sweep is
mm-exact at planes), flood bistability, #119-class statics, undefined
DXT mips (both paths decode DXT->RGBA8; the compressed-array branch is
dead code), DXT1 alpha, fog mix (ramp ~538m), lightning leak (flash==0
in production), viewer-light pops (smooth (1-d/range) ramp).
Filed #178 (A8 double-sided shell stopgap still live) and #179
(lightning flash lacks an indoor gate — dormant). The purple can only
be the fog clear color (undrawn pixels) or the outdoor ambient+sun
tint; discrimination needs ONE probe launch (ACDREAM_PROBE_LIGHT +

Full-route capture (Holtburg -> dungeon 0x0007 -> town 0xCE94 -> dungeon
-> Holtburg, 4 teleports) plus the supplemental town run. Verdict: the
render-side-CPU split is confirmed (GPU <= ~2.7ms, upd/upl/imgui ~= 0),
steady medians beat the spec assumption (worst town p50 3.6ms), and the
smoothness gap is GC: 1.5-3 MB allocated per frame drives gen2
collections 1-2/s and every town p99/max violation, while dungeon
windows (zero gen1/gen2) are spike-free at ~2000 fps. Teleport hitch
quantified at 211ms worst frame / 75.7MB single-frame allocation.
Gate decision: PROCEED to MP1 unchanged, with one recorded amendment -

- The live hit normal (-1.00,0.03,-0.03) matches NO dat polygon: a
world-space sweep of both seam cells + every portal-adjacent neighbor
(CorridorSeam_FindPolygonMatchingLiveHit) returns zero candidates. The
normal is the negated movement direction — the SYNTHETIC value
slide_sphere's opposing-normals branch records (reversed = -gDelta).
- Cell 0x8A02016E has IDENTITY rotation (the prior session's 'rotation
maps the portal planes into the -X wall' was a misattribution). The
PortalSide polys to 0x011E are +-Y planes 1.4 m beside the player's
track, perpendicular to the +X run — pos_hits_sphere's directional
cull rejects them for that movement. They ARE referenced by the dat's
physics-BSP leaves (CorridorCell_PhysicsBspLeafMembership), so retail
tests them too when approached into their plane; the dat's
keep-PortalSide / strip-ExactMatch asymmetry reads as intentional
(solid window/grate-class portals). No portal-poly filter — exactly
the blanket-skip the pickup warned against.
- Port fix: CSphere::slide_sphere's opposing-normals branch
(0x005375d7-0x0053762c) records the reversed displacement and returns
COLLIDED_TS; our port returned OK ('retail returns OK here' was a
decomp misread), letting the step complete as-is with the synthetic
collision normal that validate's epilogue then persisted as the
sliding normal the wedge absorbed on. TransitionTypes opposing branch
now returns Collided; pinned by
SlideSphere_OpposingNormals_ReturnsCollided_WithReversedDisplacementNormal
(RED->GREEN).
- Dat-backed replay (Issue137CorridorSeamReplayTests) reproduces the
live hit frame verbatim (same in/out to the millimeter, same 016E->017A
transit, same +8mm settle) and runs the corridor CLEAN: hit=no, no
sliding normal persisted, six further forward frames advance freely.
- Inspection tests extended: physics-BSP leaf membership walk +
hit-normal candidate sweep + downward-poly sweep (all report-style,
dat-gated). Pickup prompt banner'd SUPERSEDED; ISSUES #137 updated
(door half stays open); audit doc extended with the resolution.

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
OPEN - #137 not closed; the corridor re-test rides that session.

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).
Port the full family verbatim: dispatcher intersects_sphere 0x0053b440
(placement/ethereal detection, step-down cap landing, walkable probe,
grounded step_sphere_up 0x0053b310, PathClipped collide_with_point
0x0053acb0, airborne land_on_cylinder 0x0053b3d0, Collide-flag
exact-TOI cap rest) + collides_with_sphere 0x0053a880 +
normal_of_collision 0x0053ab50 + slide_sphere 0x0053b2a0. Pseudocode +
settled BN x87 ambiguities (via ACE cross-ref) + two ACE bugs found and
NOT copied (head-slide foot-disp; see doc §8):
docs/research/2026-07-05-ccylsphere-collision-family-pseudocode.md
Ethereal cylinders now flow through retail's Layer-2 override
(pc:276961) instead of the early-OK consume — same net #150 behavior,
plus retail placement-blocked-by-cylinder semantics. SlideSphere gains
a sphereNum param (retail slides the head sphere by its own
displacement, 0x0053b843).
Register: AP-6 retired; AP-83 added (PerfectClip TOI tail decoded per
ACE, dead code until missiles). Tests: CylSphereFamilyTests (grounded
step-up onto the exact platform shape, tall-cylinder block, airborne
top landing, ethereal guard); the #42 self-shadow control assertion
updated to the retail observable (denied movement — the old ~1m radial
self-push was the approximation's artifact, not retail). Suites: Core

Handoff status updated. The R5 arc's remaining work is the structural
MovementManager facade only (own slice, fresh session — pickup at
r5-wiring-handoff §V4).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Three unpack_movement parity items (facade deferred per the handoff's
own optional clause — see r5-wiring-handoff §V4 status):
1. HEAD style-on-change (0x00524440 @00524502-0052452c): both GameWindow
routing heads (remote + player) now dispatch DoMotion(style, ctor
defaults) when the UM's stance differs from the interp's current
style, BEFORE the movement-type routing — for EVERY type. Previously
style applied only through the mt-0 funnel copy, so a chase/turn UM
(mt 6-9) carrying a stance change started the move in the OLD stance
(a monster charged in NonCombat posture until the next mt-0). The
RetailObserverTraceConformanceTests exclusion note updated — the
trace filter stays (head calls can't appear in a
MoveToInterpretedState replay) but the production gap it pointed at
is closed.
2. #164 (closes): the action-replay loop threads each action's autonomy
into the dispatch params (Autonomous = the 0x1000 splice, raw
305982) — replayed actions enter the interpreted actions list with
their real autonomy instead of ctor-default false.
3. mt-0 wire flags consumed (UpdateMotion parsed them since R4-V3):
0x1 StickToObject → CPhysicsObj::stick_to_object port (0x005127e0:
resolve target, PartArray radii — 0 when shapeless, guid-as-is for
acdream's flat entity table — → PositionManager.StickTo; unresolvable
target → no stick), at BOTH case-0 tails in retail order
(@00524583-0052458e: funnel apply → stick → longjump flag);
0x2 StandingLongJump → Motion.StandingLongJump, UNCONDITIONAL write
(absent flag clears — retail @0052458e). ServerMotionState gains the
StandingLongJump field.

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).
Conformance: 2 new full-stack sticky scenarios in
RemoteChaseEndToEndHarnessTests (arrive -> stick -> strafing-target
gap+facing track -> lease expiry; unstick-on-rearm -> re-stick).
Full suite 4038 green.
Pre-commit adversarial diff review (3 lenses + per-finding refuters)
confirmed and fixed 4 findings: ObjScale-dead radius read, player
UseTime order inversion, missing teleport voyeur notify, speculative-
site radius asymmetry.
Awaiting the user visual gate: pack melee side-by-side vs retail
(attackers reshuffle + keep facing; some overlap is ACE-server-side).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
User report during the #170 gate: pack-melee monsters partly inside each
other with slightly stale facings vs retail on the same ACE. Investigation
(report-only) pinned two code-grounded causes, both already-tracked R5-V3
scope, fix APPROVED by the user:
1. TS-39 — sticky melee is a no-op: ACE arms melee chases with Sticky
(Monster_Navigation.cs:416); retail's arrival hands off to
PositionManager::StickTo -> StickyManager::adjust_offset (0x00555430,
per-tick 0.3m edge gap + facing tracking); acdream's StickTo/Unstick
seams are unbound so attackers freeze at stale arrival poses.
2. Arrival radii are zero: getOwnRadius () => 0f (the R5-V3 pin) and
RouteServerMoveTo never sets MovementStruct.Radius/Height — retail/ACE
arrive edge-to-edge with setup-derived radii (ACE PhysicsObj.MoveToObject
reads the TARGET's PartArray radius/height).
Ruled out: the between-snap collision sweep (remotes run full
ResolveWithTransition; CollisionExemption keeps creatures collidable).
Caveat recorded: ACE has no server-side monster avoidance — acceptance is
retail PARITY, not zero overlap.
ISSUES #171 filed; handoff docs/research/2026-07-04-171-sticky-melee-handoff.md

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)
+ RemoteChaseDrainBisectTests (the drain-chain pin; its first run also
demonstrated the TS-40 InWorld=false link-strip wedge shape — harness
bodies must replicate the live RemoteMotion construction).

handoff doc superseded-note added.

The retail movement-manager family the R4 MoveToManager port left as
do-not-invent seams (decomp §9f/§9g). Faithful C# ports of retail's
PositionManager facade + StickyManager + ConstraintManager + the
TargetManager voyeur system, with full conformance tests. NO wiring yet
— purely additive, no behavior change. Wiring (retiring TS-39 sticky +
AP-79 target adapter) is R5-V2/V3.
New Core classes (src/AcDream.Core/Physics/Motion/):
- StickyManager (0x00555400): follow-a-target steering. adjust_offset's
dense x87 mush decoded via ACE (StickyRadius 0.3, StickyTime 1.0,
follow speed ×5 / fallback 15) — speed-clamped signed-distance steer +
bounded turn-to-face; 1 s watchdog; Ok→initialized / non-Ok→teardown.
- ConstraintManager (0x00556090): the server-position rubber-band leash.
90% IsFullyConstrained jump gate + grounded linear brake taper.
Structural only — acdream never ARMS it (retail arms from
SmartBox::HandleReceivedPosition, which acdream lacks, with two x87
constants BN elided). IsFullyConstrained stays false = TS-35 behavior;
leash-arming + the unknown constants are a deferred issue.
- PositionManager facade (0x00555160): lazy Sticky/Constraint + fan-out.
- TargetManager (0x0051a370) + TargettedVoyeurInfo: the peer-to-peer
voyeur subscription system (0.5 s throttle, 10 s staleness,
send-on-drift-past-radius, dead-reckon GetInterpolatedPosition). A
faithful superset of the AP-79 adapter — SetTarget subscribes ON the
target; the target's HandleTargetting pushes updates back.
- IPhysicsObjHost: the CPhysicsObj back-pointer seam (position/velocity/
radius/contact/GetObjectA + target-tracking fan-out) the App wires per
entity in V2/V3. MotionDeltaFrame: mutable retail-Frame delta accumulator.
Supporting:
- TargetInfo extended to the full retail 10-field struct (additive
defaults keep the R4 4-arg call sites compiling).
- MoveToMath: signed CylinderDistanceNoZ, NormalizeCheckSmall,
GlobalToLocalVec.
- Rename: the misnamed AcDream.Core.Physics.PositionManager (a remote
anim+interp per-frame combiner, NOT the retail facade) → RemoteMotion
Combiner, freeing the name and removing the ambiguity that breaks every
file importing both Physics + Physics.Motion (GameWindow will in V2/V3).
Tests: 42 new conformance cases (Sticky/Constraint/Position facade +
TargetManager incl. the full cross-entity voyeur round-trip). Full suite
4006 green (+2 skipped), no regressions.
Decomp + ACE cross-ref + port plan: docs/research/2026-07-03-r5-managers/.

#163: remove [autowalk-gate] (+ _lastAutowalkGateLogTime throttle clock,

feed), and the short-lived [MOVETO-CANCEL] #162 capture probe. The
durable ProbeAutoWalk family (PhysicsDiagnostics owner + DebugPanel
toggle + the permanent [autowalk] probe sites) stays.
#162 closed WITHOUT adaptation: user A/B says retail does not glide, and
post-#161 acdream matches (user-verified walk/run-by-distance movetos +
clean mid-chain key takeover). Head-interrupt + CancelMoveTo re-audited
retail-verbatim against the raw (unpack_movement 0x00524440,
interrupt_current_movement 0x005101f0, MoveToManager::CancelMoveTo
0x00529930 armed-gate); the launch-162 capture shows ACE's mt-0
reflections carry the mover's real locomotion, so cancels never strand
the legs. The old glide was killed by the R4-V5 stack + #161's
apply-pass params fix. Evidence trail in ISSUES Recently-closed #162.

The local player now runs server MoveTos through the same verbatim
MoveToManager remotes got in V4. One commit, GameWindow + controller,
per the no-fan-out rule for coupled slices.
P1 gate (V0-pins.md P1, ported verbatim): CPhysics::SetObjectMovement
(0x00509690 @0050972e) drops any movement event whose wire autonomous
byte is set when the addressed object IsThePlayer - ACE's self-addressed
MoveToState reflection (MovementData.cs:162 IsAutonomous=1) never
reaches unpack_movement, which is what makes the retail unconditional
unpack-head interrupt safe. Gate placed AFTER the sequence gates
(retail order). The stale "ACE follows every mt=0x06 with an mt=0x00"
comment block dies with the code it excused (its causal story was
pre-#75; refuted in V0-pins P1).
Run-rate re-anchor (P1 contingency NOT needed - no AD row): the echo
tap ApplyServerRunRate is deleted outright. Both retail feeds already
exist: PlayerDescription skills via SetCharacterSkills (K-fix7) into
InqRunRate (preferred by apply_run_to_command/get_state_velocity), and
the mt-6/7 my_run_rate wire write (M13) now performed for the player by
the shared RouteServerMoveTo. The tap's InterpretedState.ForwardSpeed
overwrite was a pre-R3 mechanism that fought the ported machinery.
B.6 auto-walk deleted wholesale (~330 lines): fields, Begin/End/
DriveServerAutoWalk, IsServerAutoWalking, AutoWalkArrived, the
autoWalkConsumedMotion gates, the #69 turn-dir edge synthesizer, and
the relocated AutoWalkArrivalEpsilon/AutoWalkTurnRateFor constants
(AD-26 retired - the invented 5/30-degree bands are gone; arrival is
retail's distance predicate; turn-first is the TurnToHeading node).
TS-36 retired: Motion.InterruptCurrentMovement binds to
MoveTo.CancelMoveTo(ActionCancelled). Movement-key edges (ctor-default
params carry the 0x8000 CancelMoveTo bit), Shift (set_hold_run
interrupt:true), jump(), StopCompletely, and teleport all cancel a
running moveto through the retail chain - verified by controller-level
tests, not assumed.
MoveToComplete seam WIDENED to natural completion (Core): retail's
BeginNextNode empty-queue completion is inline CleanUp+StopCompletely
(raw @00529d47) and notifies nothing - the client-addition seam had to
fire there (both sticky and non-sticky exits) or AD-27's deferred
close-range Use/PickUp re-send never fires. Never fires on CancelMoveTo.
AD-27 re-anchored from the deleted AutoWalkArrived event.
InstallSpeculativeTurnToTarget rewired through the player's manager
(retail 9a/9b client-initiated shape): close-range -> TurnToObject,
far -> MoveToObject; AP-23 radius buckets + the #77 CanCharge
prediction survive as the params source (row re-anchored).
Per-tick: MoveTo.UseTime() at the old DriveServerAutoWalk slot
(provisional until R6, per the plan's placement decision); the P4
player-side TargetTracker twin (fields + pre-Update feed) mirrors the
remote adapter (AP-79 row widened). HitGround dual-call added on the
player landing edge AND the remote landing site - the latter closes a
V4 wiring-contract gap the adversarial review caught (retail 2d order:
minterp then moveto; without it a landing NPC's moveto never re-arms).
Also from the adversarial review: the mt-8 unresolvable-target degrade
now performs retail's params.desired_heading = wire_heading
substitution (decomp 2f case 8; invisible against ACE per P6, required
for the verbatim degrade); the V4 remote MoveToManager binding gets a
real curTime clock (the ctor stub advanced 1/30s per READ, skewing the
progress/fail-distance windows - note: the pending V4 NPC smoke ran on
the skewed clock); TS-33 row extended with the orientation-diff gap
(ApproxPositionEqual vs retail Frame::is_equal full-frame compare - a
stationary heading snap does not reach the wire; masked against ACE,
R7 outbound scope owns the fix).
MoveToMath gains HeadingFromYaw/YawFromHeading (the P5 scalar bridge
for yaw-authoritative bodies - the player's heading snap must write
Yaw, not the quaternion the controller re-derives every frame).
Tests: 3,956 green (+8). New: MoveToManagerCompletionSeamTests (arrival
fires once with None, no refire, cancel never fires, sticky handoff
order) + PlayerMoveToCutoverTests (EnterPlayerModeNow-shape rig: walks
to arrival with zero user input and zero MotionStateChanged frames -
the #75 invariant by construction; TurnToHeading rotates Yaw and snaps
exact; W-edge and jump cancel without firing complete). W6 edge suite
retargeted from the deleted echo tap to a direct apply pass (the
regression lives in ApplyInterpretedMovement, not the wire trigger).
Spec: docs/research/2026-07-03-r4-moveto/r4-port-plan.md section 3 V5.
