MovementParameters gains the verbatim selection family: GetCommand 0x0052aa00 (the walk-vs-run cascade INCLUDING the CanCharge 0x10 fast-path ACE dropped - retail's default can_charge=false + the fast-path present, the A13+A15 canceling-pair trap avoided; inclusive threshold edge per the raw), TowardsAndAway, GetDesiredHeading per the live Ghidra decompile (fwd-towards 0 / fwd-away 180 / back-towards 180 / back-away 0), FromWire/FromWireTurnTo (UnPackNet semantics, all 18 A4 masks round-tripped). New MoveToMath: HeadingDiff per the live Ghidra decompile of 0x00528fb0 (the 360-diff NOT-TurnRight mirror + F_EPSILON 0.000199999995f - the BN "arg unused" artifact corrected), HeadingGreater (the visible TurnRight idiom), PositionHeading/Get/SetHeading reusing the codebase's single yaw-heading convention (P5), CylinderDistance (PDB arg order; planar-minus-radii shape documented as the interpretation - the raw's x87 body is garbled; seam noted). MovementType gains Invalid + retail 6/7/8/9; MovementStruct widened (ObjectId/TopLevelId/Pos/Radius/Height/Params, additive); WeenieError += 0x0B/0x36/0x37/0x38/0x3D with retail-meaning doc comments. 148 new conformance tests. Full suite: 3,860 passed. Implemented by a dedicated agent against the V0-pinned spec; scope + suite independently verified. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
