docs: file #170 — remote creature chase+attack renders wrong vs retail

User retail side-by-side during R5-V2 visual gate: chasing+attacking monster
glides, over-frequency, uniform attack anims (retail correct on same ACE →
client-side). Decomposes into #159 (attack cmd numbering) + pending_motions
loop + dead-reckon-vs-locomotion glide. NOT V2 (chase tracking works).

+## #170 — Remote creature chase+attack renders wrong vs retail (glide, over-frequency, uniform attack anims)
+
+**Status:** OPEN
+**Severity:** MEDIUM (visual — remote combat / aggro)
+**Filed:** 2026-07-03 (user retail side-by-side during the R5-V2 visual gate)
+**Component:** animation, remote entity, combat
+
+**Description:** A monster chasing + attacking the player (aggro) renders wrong
+vs the retail client running against the SAME local ACE. User side-by-side:
+retail plays proper animations, positions the monster better, plays DIFFERENT
+attack animations (variety), and the attack-animation FREQUENCY is correct;
+acdream shows the creature "stuck in the attack animation, gliding after me."
+Because retail gets the identical ACE motion stream and renders it correctly,
+the divergence is CLIENT-side (acdream's UM/animation handling), **not** ACE.
+
+Three distinct sub-divergences:
+1. **Wrong/uniform attack animations** → likely **#159** (CombatAnimationPlanner
+   uses 2013-decomp command numbering, not ACE/DRW; the attacks
+   `0x10000062/63/64` misclassify → wrong or same animation).
+2. **Over-frequency / stuck attack** — motion trace: ACE streams attack UMs
+   (`mt=0x00 cmd=0x62/0x63/0x64 spd=0.97`) on top of the `mt=0x06` chase;
+   acdream's `pending_motions` completes+re-queues in a tight MOTIONDONE loop
+   (`pending=True` spam) → over-plays. R3/R4 pending_motions/MotionDone area.
+3. **Glide** — the creature's position moves (mt-6 moveto + UP dead-reckon) but
+   no locomotion legs play (attacks override) → smooth slide. AP-80 / #160
+   dead-reckon-vs-animation family.
+
+**Evidence:** `ACDREAM_DUMP_MOTION` trace for guid 0x80000244 — `mt-0 stance 0x3C`
+→ `mt-6 chase spd 2.03` → stream of `mt-0` attacks `0x62/63/64 spd 0.97`;
+MOTIONDONE loop between `0x8000003C` (stance) and the dispatched motion.
+
+**NOT V2/R5:** the voyeur target-tracking correctly makes the creature chase
+(the `mt-6` is proof); this is the animation/position layer.
+
+**Where:** `MotionInterpreter`/`AnimationSequencer` attack-motion dispatch +
+`pending_motions`; `CombatAnimationPlanner` (#159); `ServerControlledLocomotion`
++ remote dead-reckoning (glide).
+
+**Acceptance:** side-by-side with retail — a chasing+attacking Mite Scamp shows
+correct attack-animation variety, correct frequency, and steps/runs (no glide).
