CydandClaude Fable 5 ebf0d8c23f BT410 Phase 5.3.2: DRIVABLE mech -- authentic control interpretation + locomotion 
The mech now drives from the authentic control chain (faithful route). Verified
headlessly: full throttle -> walks straight at top speed (30 u/s) along heading;
throttle+turn -> walks a circle (radius = speed/turnRate); neutral -> holds pose;
zero Fail.

MechControlsMapper::InterpretControls (mechmppr.cpp @004afd10) -- installed as the
mapper's per-frame Performance (roster slot 0, ticks before the mech):
- speedDemand = topSpeed*throttle*fwdScale (reverse inverts); soft stick (square)
  / pedal (cube) response; Basic=stick turn, Std/Vet=pedal turn; speed clamped
  while turning hard. Reads owner stride via Mech accessors.
- BT_FORCE_THROTTLE/BT_FORCE_TURN dev hooks for headless verification.

Mech::Simulate drive -- consumes the mapper demands:
- accelerate currentBodySpeed toward speedDemand (maxBodyAcceleration);
- authTurnRate = lerp(walkingTurnRate, runningTurnRate) by ground speed + over-run
  falloff (mech4.cpp master-perf @0x4aa3d3);
- integrate heading via Quaternion::Add(prevPose, (0,turn*rate*dt,0));
- facing = world -Z basis (GetFromAxis(Z_Axis)); worldLinearVelocity = facing*spd;
- integrate position (increment-1 core).

MECH.HPP: 9 named locomotion members out of reservedState (now [211]) --
walking/runningTurnRate, reverse/walkStrideLength, reverseSpeedMax,
forwardThrottleScale, maxBodyAcceleration, body/currentBodySpeed. BRING-UP
DEFAULTS (authentic values come from the model resource + LoadLocomotionClips --
next refinement).

Deferred: gait-clip-exact advance + leg anim (needs animation subsystem/renderer),
model-resource sourcing, terrain drop, torso/free-look aim, telemetry filters.

CydandClaude Fable 5 1f2f8ac42a Phase 5.1: MechControlsMapper publishes its 20 control-input attributes 
Reconstructed the MechControlsMapper attribute table (StickPosition..PilotArray,
IDs 3-0x16 chained from Subsystem::NextAttributeID==2) + the real members
(stickPosition ControlsJoystick, throttle/pedals/speed/turn Scalars, the look/
torso ControlsButtons, control/display/pilotArray ints) + AttributePointers[] +
AttributeIndex (chains Subsystem::AttributeIndex). Fixed the mapper hierarchy
statics in BTL4MPPR.CPP: L4/RIO/Thrustmaster ClassDerivations now chain correctly
(L4 defined first for static-init order) and all use MechControlsMapper::
AttributeIndex so the mapper instance publishes the control attributes the
streamed mappings bind to.

Mech still constructs (33 subsystems). The post-construction crash is UNCHANGED
(GetAttributePointer, attribute=0x13) -> so it's NOT the mapper; a streamed
AttributeWatcher (numeric ID 19) resolves on another object via GetSimulation.
Next diagnostic: which object/subsystemID the watcher targets. BT: 42 ok.

CydandClaude Fable 5 d9b34ddc63 source410: THE WHOLE 4.10 TREE COMPILES - 11/11 under the fleet's BC++ 4.52 
All 10 surviving original TUs plus the reconstructed BTL4APP.CPP pilot build
clean with the authentic OPT.MAK flags (compile410.sh --sweep). First time
the 4.10 BattleTech source has compiled since 1996.

- layout_probe.cpp: the period compiler measures 1995 layouts from the
  surviving headers; validated 3/3 against binary alloc sizes (BTMission
  0xFC, BTL4ModeManager 0xC, BTRegistry 0x10). Base boundary: Simulation
  0xD0 / Entity 0x1C4 / Mover 0x300 / JointedMover 0x328 => Mech-own region
  0x328-0x854 (MECH-LAYOUT.md staging worksheet).
- 13 staged headers close the family ([T3] reserved[]-parked layouts;
  interfaces PROVEN by the surviving consumers): MECH, MECHSUB, HEAT,
  POWERSUB, MECHWEAP, EMITTER, MECHMPPR, BTPLAYER (BTPlayer__MakeMessage =
  Player's 8 args + roleName/teamName [T1 via BTREG]), PROJTILE, MISSILE,
  BTL4MPPR, BTL4VID + the round-2 BTCNSL/BTSCNRL.
- compile410.sh: PCH gate retired (bt.hpp/mungal4.hpp full include sets),
  DPL SDK roots on the include line.
- BTL4APP.CPP: appmgr include + GetApplicationManager()->GetFrameRate() +
  ResourceDescription:: scoping; Fail() held at its recorded line 400.
- Evidence ledgers: STAGED-HEADERS.NOTES.md, MECH-LAYOUT.md, BACKFILLS,
  BTCNSL (binary-recovered console wire IDs), BTSCNRL.

Remaining for a linkable BTL4OPT: the ~40 missing TU bodies (917-function
manifest) - the header skeleton they grow into now exists and compiles.
