 | TS-42 | Per-tick DRAIN ORDER inverted vs retail: acdream's `TickAnimations` runs `HandleTargetting` → `Movement.UseTime` (the R5-V5 MovementManager relay, ex-loose `MoveTo.UseTime`) FIRST and the animation-completion drain (Sequencer.Advance → AnimDone hooks → `MotionTableManager.AnimationDone`/`UseTime` → `CMotionInterp.MotionDone` pops) LAST, so every motion-completion-gated decision (`BeginTurnToHeading`'s `motions_pending` wait) sees a queue that is one frame STALE — the unblock after a stop/swing lands one frame later than retail. Retail order (pinned from the named decomp this session): `UpdatePositionInternal` (CPartArray::Update + `process_hooks` @0x00512d3d — the drain) runs BEFORE `TargetManager::HandleTargetting` @0x00515989 → `MovementManager::UseTime` @0x00515998 → `CPartArray::HandleMovement` @0x005159a4 (zero-tick sweep) in `UpdateObjectInternal` | `src/AcDream.App/Rendering/GameWindow.cs` (`TickAnimations` per-entity phase order; the R2-Q4 comment already marks the placement "provisional until R6") | Bounded to exactly ONE frame (~16 ms) of extra latency per completion-gated event; every queue eventually drains identically (RemoteChaseEndToEndHarnessTests conformance) | Motion-completion-gated transitions (chase turn start, post-swing re-arm) systematically lag retail by one frame; under compound churn the lag can cost an extra retry cycle | `CPhysicsObj::UpdateObjectInternal` 0x005156b0 + `UpdatePositionInternal` 0x00512c30 (`process_hooks` @0x00512d3d); retire in R6 (retail UpdateObjectInternal order) |
 | TS-44 | NPC UpdatePosition hard-snaps (position @`OnLivePositionUpdated` + orientation + velocity/cycle adoption) are SUPPRESSED while the entity is stuck (`PositionManager.GetStickyObjectId() != 0`) — an adaptation of retail's chain semantics to the legacy snap path: retail routes UP corrections through the InterpolationManager into the SAME per-tick `PositionManager::adjust_offset` chain where `StickyManager::adjust_offset` OVERWRITES them while armed (0x00555190 order, 0x00555430 assigns m_fOrigin), so a server correction can never fight an armed stick; the legacy NPC path snaps OUTSIDE the chain, producing snap-out/steer-back position flapping + stale-facing stomps (the 2026-07-04 #171 gate residuals). Bookkeeping (`LastServerPos/Time`, cell) still records; server truth reasserts on the first UP after unstick, bounded by the 1 s sticky lease | `src/AcDream.App/Rendering/GameWindow.cs` (`OnLivePositionUpdated` NPC section, `snapSuppressedByStick` gate) | Retail's mechanism (sticky-overwrites-interp) is unreachable until the NPC path gets the interp-queue architecture (the player-remote branch already has it — the R5-V3 combiner→sticky chain); the gate reproduces the retail-observable behavior on the snap architecture | A stick that stays armed while ACE moves the monster far (shouldn't happen — sticks follow the target by construction) would drift until unstick+next UP; worst case bounded by the 1 s lease + the next UM re-arm | `PositionManager::adjust_offset` 0x00555190; `InterpolationManager` UP routing (`CPhysicsObj::MoveOrTeleport`); retire when the NPC path unifies onto the interp queue (S6/R6) |
+| TS-46 | Player/remote collision spheres are passed as TWO SCALARS (radius, capsule-top height) and reconstructed by `SpherePath.InitPath` (foot center at `radius`, head center at `height − radius`) — retail passes the Setup's SPHERE LIST verbatim (`CPhysicsObj::transition` 0x00512dc0 → `init_sphere(GetNumSphere, GetSphere, m_scale)`). With the corrected callers (0.48, 1.835 = Setup.Height) the reconstruction sits 5 mm off the dat: foot center 0.480 vs dat 0.475, head center 1.355 vs dat 1.350 (human Setup 0x02000001 spheres `(0,0,0.475) r=0.48`, `(0,0,1.350) r=0.48`). Remotes also use the hardcoded HUMAN dims regardless of creature Setup/scale. (The pre-2026-07-06 value 1.2f put the head TOP at 1.2 m — 0.63 m of headless character; the #137 window climb. Fixed same day.) | `src/AcDream.Core/Physics/TransitionTypes.cs` (`InitPath`), `src/AcDream.App/Input/PlayerMovementController.cs` + `src/AcDream.App/Rendering/GameWindow.cs` (the two `sphereHeight:` call sites) | The scalar API predates the Setup ingestion; 5 mm is below the visual/feel threshold for the human capsule and keeps every captured-input replay fixture byte-identical | 5 mm offsets can flip marginal grazes near the r−ε/r+ε knife edges (today's seam class); creature-scale remotes collide with human-sized capsules until setup-derived dims are plumbed | `CPhysicsObj::transition` 0x00512dc0; dat Setup 0x02000001; retire by plumbing the Setup sphere list into `InitPath` |
+| TS-45 | `SphereCollision` (the shadow-object Sphere response) is a hand-rolled 3-D wall-slide that ALSO calls `SetSlidingNormal` — retail's `CSphere::intersects_sphere` (0x00537A80) dispatches `CSphere::slide_sphere` (0x00537440), which slides in-frame and never writes `collision_info.sliding_normal` (the only in-transition writer is `validate_transition` 0x0050ac21). Same leak class as the #137 mechanism-2 stubs fixed 2026-07-06 (BSPQuery Contact branch); left in place because the response's blocking semantics for sphere-shaped server objects are untested against the real slide and #171 sticky-melee behavior is freshly gated | `src/AcDream.Core/Physics/TransitionTypes.cs` (`SphereCollision`, the `ci.SetSlidingNormal` tail) | The in-frame push-out already moves the check position; the extra sliding normal only persists on transition success, and pure-Sphere shadow shapes are rare (most creatures/statics are CylSphere, which routes through the real `SlideSphere` since #172) | A sphere-shaped object touch persists a normal retail would discard — an exactly-anti-parallel follow-up push absorbs to a zero offset (#137 wedge class) at that object until an oblique input clears it | `CSphere::intersects_sphere` 0x00537A80 → `slide_sphere` 0x00537440 (pc:321678+); fix = route the tail through `Transition.SlideSphere` like `CylSlideSphere` does |
 | TS-43 | Remote teleport has no `teleport_hook` equivalent: retail tears down the position managers on every teleport (`CPhysicsObj::teleport_hook` 0x00514ed0 — `CancelMoveTo(0x3c)` @0x00514edf, `PositionManager::UnStick` @0x00514eee, `StopInterpolating`/`UnConstrain`); acdream's remote teleport is a bare UP hard-snap, so a stuck/chasing remote that the server teleports keeps its stick/moveto for up to the 1 s sticky lease / next UM. The LOCAL player side IS wired (R5-V3: `PlayerMovementController.SetPosition` → `PositionManager.UnStick`; the moveto cancel was already there via `StopCompletely`; the teleport-arrival site also fires the hook's tail — `EntityPhysicsHost.NotifyTeleported` = `TargetManager::ClearTarget` + `NotifyVoyeurOfEvent(Teleported)` @0x00514f1b-0x00514f28, which is what makes mobs stuck to the player drop their sticks on a recall) | `src/AcDream.App/Rendering/GameWindow.cs` (`OnLivePositionUpdated` — no teleport-flag manager teardown for remotes) | Remote teleports are rare (recalls/summons); the sticky 1 s lease + UP hard-snaps self-correct within a second; wiring it properly wants the UP teleport-stamp plumbing (TS-26's stamp work) | A teleported-away attacker briefly steers toward its pre-teleport target from the new location (≤1 s) before the lease/next-UM corrects it | `CPhysicsObj::teleport_hook` 0x00514ed0; retire with the TS-26 UP-stamp port |
