+**Model-resource sourcing (2026-07-21, VERIFIED).** The ctor now sources the
+authentic per-mech `walkingTurnRate` / `runningTurnRate` / `maxBodyAcceleration`
+/ `forwardThrottleScale` from the GameModel resource
+(`SearchList(GameModelResourceType)` → `ModelResource`), replacing those
+bring-up defaults. Each read is SANITY-GUARDED (out-of-band → keep the default)
+because BT411 flags parts of the ModelResource layout as mis-decoded — but the
+live values came back clean and authentic: **walkTR=75°/s, runTR=50°/s,
+maxAcc=30 u/s², throttleAdj=1.0** (walking turns faster than running; maxAcc
+matches BT411's madcat note), confirming the struct layout is correct for these
+fields. Verified drive: at walk speed the authentic 75°/s tightens the turn
+circle to r≈6.9 (=speed/turnRate). Still on bring-up defaults:
+`reverseStrideLength` (top speed) / `walkStrideLength` / `reverseSpeedMax` —
+their authentic source is `LoadLocomotionClips` (measured from the walk/run
