Two new PlayerMovementController-level tests, exercising the real
production controller (not just the Core-level composed model in the
prior commit):
- Update_AnimationRootMotion_WalkSpeedUnaffectedByResidualVelocityFix:
ordinary root-motion walking (no fall/collision in flight) advances by
exactly the authored per-tick delta for 30 ticks with BodyVelocity
staying exactly zero throughout - the fix is a complete no-op for the
common case, pinning the L.3c hazard
(claude-memory/project_physics_collision_digest.md's DO-NOT-RETRY
table) at the Runtime level alongside the existing Core-level
GroundedRootMotion_FrictionThreshold_DoesNotHammerLocomotionTests pin
(unmodified, still green).
- Update_RunningJumpLandsOnFlatGround_ResidualVelocitySurvivesAndDecays_NotFrozen:
a real charged running jump lands on flat ground and its residual
horizontal speed survives the first post-landing tick, then measurably
decays (dot(velocity, (0,0,1)) ~ 0 < 0.25, so friction engages here,
unlike the sloped roof capture where it doesn't).
Building the second test surfaced two genuinely separate, already-
correctly-scoped mechanisms unrelated to #265/#166, requiring no
production change: MotionInterpreter.LeaveGround (CMotionInterp::
LeaveGround 0x00528b00, R3-W4/J7/J8) recomputes velocity from the
CURRENT interpreted command on the grounded->airborne edge tick, so the
test holds Forward for one extra tick before releasing it; and
MotionInterpreter.ApplyCurrentMovementInterpreted's AP-77 "animation-less
/headless movement fallback" (already correctly scoped in the
divergence register) independently rewrites grounded velocity when no
DefaultSink is wired, so the test wires a minimal
FakeAnimationDispatchSink to match production's always-wired sink.
