The heat economy now bites back, verified under sustained fire:
- Ballistic gate 1 (@4bbd36): destroyed-state or own-sink FailureHeat pins
full recoil + the unavailable alarm (the NoAmmo roach-motel re-asserts).
- CheckForJam (@4bbfcc): p = 0.41*T/failT clamped [minJamChance, 1.0], rolled
per granted shot against the MUNGA uniform Random. Interim heat-degraded
gate stands in for the deferred LiveFireEnabled novice switch (the exact
spurious-cold-jam trap the BT411 port documented). VERIFIED: SRM6s jam at
T~1200-1320 after riding past the authored 1000-degree threshold, and stay
jammed (mission-reset recovery only) -- authentic.
- Emitter hard gate (@4baab9): FailureHeat drops the beam state + charge each
frame; SELF-RECOVERING once conduction cools the sink below failure.
VERIFIED: the PPC settles into an emergent thermal duty cycle -- fire at
~1930K, spike to 2562K, shutdown, cool, refire -- firing exactly as fast as
its sink sheds heat; the lasers oscillate around ~2200K.
Zero Fail. Deferred: LiveFireEnabled/HeatModelOff experience gates,
mech-disabled gate halves, coolant depletion, jam recovery via mission reset.

Weapons dump firing heat into their own sinks, sinks conduct through the
Condenser bank into the central HeatSink, temperatures drive the degradation/
failure alarms, and every powered subsystem tracks its generator through the
electrical state machine. Verified: the authentic fire-discipline game -- a PPC
spikes 77->709K per shot, relaxes to 441K across its 5s reload, and sustained
fire climbs 441->674->838->960K, brushing the authored 1000K degradation
threshold. All calibration values match the BT411 audit exactly (central bank
1.39e6, PPC sink 174000, thresholds 77/1000/2000).
- HEAT: HeatSinkSimulation (@004ad924 absorb->T->load->conduct->alarm),
ConductHeat/ComputeHeatFlow (@004ad8ac/@004ad9ec two-body equilibrium
relaxation; flow==0 exactly at uniform T), UpdateHeatLoad (15-sample filter);
heat-state enum + accessors; installed by the HeatSink ctor.
- WIRE-VERIFIED: HeatSink resource gains linkedSinkIndex -- THE missing
ancestry int that shifted every descendant block +1 (voltageSourceIndex had
been reading the linked-sink index: "power sources" appeared to be
Condensers). Conduction topology wired from it at construction:
weapons->Condensers1-6->central; Generators->Condensers; Reservoir->central.
- MECHWEAP resource: authentic pip tail (pipPosition int + pipColor 3 floats +
pipExtendedRange int) per the BT411 verified overlay; with linkedSinkIndex
this closes the whole +3 alignment mystery (ProjectileWeapon pad deleted).
True bhk1 reads: PPC recharge 5.0s (not 1.0), discharge 0.99s, range 900.
- POWERSUB: ctor resolves voltageSourceIndex -> GeneratorA-D (wire-verified),
taps via Generator::TapVoltageSource (-1 when full); PoweredSubsystemSimulation
(@004b0bd0) electrical FSM (Starting/NoVoltage/Shorted/GeneratorOff/Ready);
GeneratorSimulation partial (start/short-recovery timers).
- Weapons: power step at sim head; Loading recharge gated on electrical Ready
(authentic @4bbdf5); FireWeapon dumps firing heat. HEAT UNITS: the chain is
1e7-native with TWO authoring conventions -- energy weapons store small
(PPC=11, x1e7 from the energy algebra), ballistics store native (SRM6=5.06e7,
dumped raw; double-scaling it was the bring-up runaway-temperature bug).
- SENSOR: authentic gating (@004b1c4c) -- power step, electrical-Ready gate,
heat-state switch (Degradation x0.5 / Failure 0). Verified Ready + 100%.
Deferred: coolant depletion/venting, the novice HeatModelOff gate, the charge
model (TrackSeekVoltage/voltage sag/I2R), weapon gate 1 + jam roll, the central
sink's forward-linked drain. Zero Fail across fire + neutral runs.

The SRM6 MissileLaunchers now run the authentic ballistic fire cycle against
their linked AmmoBins, wire-verified end to end.
- PROJWEAP ProjectileWeaponSimulation (PARTIAL, binary @004bbd04 -- fully
recovered in the BT411 RE): one trigger-edge sample; the dry-bin gate pins
NoAmmo(7) every frame; Loaded(2) -- the AMMO PULL LIVES IN THE CALLER (a
denied shot does the 4->2 denial blip with NO ammo pulled -- early-returning
gates from FireWeapon while the caller cycles the alarm is the 1995 "denied
shot fakes a full firing cycle" defect class); granted -> Firing ->
FireWeapon -> Loading (or NoAmmo on the emptying pull), recoil=rechargeRate;
Loading bleeds recoil -> Loaded when a round is chambered, dial animates;
Jammed(5) held; NoAmmo(7) = the roach-motel (re-asserts unconditionally).
Deferred: electrical step, gate 1, eject, jam roll, HasActiveTarget.
- AMMOBIN: FeedAmmo() + GetAmmoState() (1 round-ready / 2 EMPTY).
- ammoBinLink wired from the resource's ammoBinIndex (the bin's roster slot).
- WIRE-VERIFIED RESOURCE ALIGNMENT: a raw-stream dump pinned the
ProjectileWeapon field block +3 ints past our staged struct (the MechWeapon
resource ancestry runs 3 ints short -- the pip-family fields). Fixed with
resourceAlignPad[3]; phantom muzzleVelocity/missileCount tail dropped.
Confirmed on-wire: ammoBinIndex=27/29 (the exact bin slots), tracerInterval=1,
minTOF=0.5, minVolt%=0.3, minJam=0.05, missileCount=6 (an SRM6!).
- MECHWEAP: weapon-state enum extended to the full 1995 set (DryTrigger 1,
Jammed 5, TriggerDuringJam 6, NoAmmo 7; count 8).
- MISLANCH FireWeapon PARTIAL (@004bcc60: heat + salvo spawn only -- spawn
needs the entity/targeting waves).
VERIFIED headlessly (BT_FORCE_FIRE): bins resolve with the authored 24 rounds;
SRM6s fire 6-missile salvos at the authored 1s cadence, rounds 24->0; after
the 24th salvo the launcher goes DRY and stays silent across ~3,000 subsequent
fire events while the energy weapons keep cycling. Zero Fail.

The energy weapons now run a live fire cycle, and the REAL trigger wiring is in
place: the 1995 MechWeapon attribute table (binary @0x511890) is published with
PINNED IDs, so the streamed per-mech fire-button mappings bind TriggerState
(0x13) -> fireImpulse and the controls push writes the trigger into the weapon.
- MECHWEAP: attribute enum + table (PercentDone 0x12, TriggerState 0x13,
DistanceToTarget 0x14, TargetWithinRange 0x15, WeaponRange 0x16,
EstimatedReadyTime 0x1A, RearFiring 0x1B, WeaponState 0x1C). Pads bridge the
chain gap 2..0x11 -- LOAD-BEARING: AttributeIndexSet::Build leaves uncovered
gap slots as uninitialized garbage, so every ID up to the max must be covered
(they shrink to the authentic 0x0F..0x11 when the parent attribute waves land;
SENSOR.HPP pins PoweredSubsystem::NextAttributeID at 0x0F).
- MECHWEAP: fire-machine members (fireImpulse/previousFireImpulse,
rechargeLevel, rangeToTarget, effectiveRange, estimatedReadyTime, recoil,
weaponAlarm 0/2/3/4); CheckFireEdge (@004b9608, BIT-PATTERN int compare --
TriggerState carries raw ControlsButton ints whose release value is a float
NaN; IEEE compare would latch the detector shut); ComputeOutputVoltage
(@004b9c9c recharge dial).
- EMITTER: EmitterSimulation (PARTIAL @004baa88) -- Firing/Loaded/Loading FSM
on the weapon alarm, viewFireEnable gate at Loaded->Firing, recoil-decay
recharge over the authored RechargeRate seconds; FireWeapon (PARTIAL
@004bace8) discharge bookkeeping; ChargeLevel re-pinned to the authentic
0x1D; index re-chained to MechWeapon's. Deferred: electrical charge model
(TrackSeekVoltage), heat dump, HasActiveTarget gate, beam/damage submission.
- BT_FORCE_FIRE dev hook: trigger pulse whenever Loaded (auto-fire cadence).
VERIFIED headlessly: forward view -- PPC_1/2 + ERMLaser_1 cycle FIRED->LOADED
at the authored 0.6s/1s cadence, rear lasers silent; BT_FORCE_LOOK=3 -- ONLY
the rear lasers (ERMLaser_2/3) fire. The view-fire x fire-FSM interlock holds
both directions. Zero Fail. (SRM6 ballistic FSM = a later increment.)

Completes the weapon-side half of the look commit:
- MECHWEAP: real rearFiring/viewFireEnable members (binary @0x334/@0x3E0) +
accessors. Ctor resolves REAR-FIRING authentically (@004b99a8 tail): the
mount SEGMENT site name is tested for the 'b' (back) marker -- only the back
gun ports (sitelbgunport/siterbgunport) carry it. Spawn = forward-armed.
- MECH CommitLookState: re-arms every roster weapon per view (forward =
non-rear, LOOK-BACK = rear-mounted, side/down = none) and flips the HUD
reticle pip group with the authentic Reticle::Front/RearFiringWeaponsOn flags
(BT411's raw "bits 1/2" resolved to their 1995 names).
- MECHWEAP: defined MechWeapon::MessageHandlers (0-entry set inheriting the
Subsystem chain) -- it was declared-but-undefined, and the surviving CODE
PPC.CPP binds the inherited name into PPC::DefaultData; the zero-filled
common block was a latent NULL deref (same trap as Emitter::AttributeIndex).
Discovery: the TEST.EGG mech genuinely mounts TWO REAR LASERS (ERMLaser_2/3 on
the b-ports). Verified on a full-clean baseline (engine 181 + bt 42, 0 fail):
look-behind arms exactly the rear lasers, disarms the other five,
pipMask=0xfffffffe; neutral run holds forward-armed; zero Fail.
build410.sh HARDENED against the stale-obj layout-skew trap this wave exposed:
cc() skipped recompiles on obj-vs-.cpp timestamps only, so the MECHWEAP.HPP
member additions left emitter.obj on the OLD MechWeapon layout -- its
chargeLevel=0.0f write landed exactly on the new rearFiring (a silent cross-TU
struct skew, heisenbug-grade). cc() now honors header stamps: a source410
engine-header edit invalidates every bucket, a BT/BT_L4 header edit
additionally invalidates the game buckets. CODE/ is immutable, no stamp needed.

Reconstructs the binary's five-state LOOK machine (controls mapper tail,
part_013.c:396-459) as proper members/methods:
- MECHMPPR: LookState enum (None/Left/Right/Behind/Down) + lookState/
previousLookState (out of reserved[24] -> [22]). InterpretControls picks the
state from the look buttons each frame and on a CHANGE calls
Mech::CommitLookState. BT_FORCE_LOOK=<1..4> dev hook.
- MECH: authored look angles lookLeft/Right/Front/BackAngle (deg->rad from the
GameModel resource, guarded) + lookPitch/lookYaw + CommitLookState(int):
side looks yaw by the authored angle, look-behind = yaw pi + lookBackAngle
pitch, look-down = lookFrontAngle pitch, forward = identity. The per-frame
eyepoint compose in Simulate adds the live Torso elevation on top.
(reservedState [208] -> [202].)
- Deferred inside the commit (needs MechWeapon viewFireEnable/rearFiring):
per-view weapon fire re-arm + HUD pip group-mask flip.
Verified headlessly: model reads clean authored angles (L=60 R=-60 F=-10 B=0
deg -- ModelResource layout confirmed again); BT_FORCE_LOOK=3 fires ONE commit
([look] state=3 yaw=3.14159 pitch=0) and the per-frame compose holds eyeYaw=pi
with eyePitch=0.349066 (lookBackAngle + the 20deg-clamped elevation). Zero Fail.

Investigated the next planned binding (elevation -> gun joints jointlgun/
jointrgun) before implementing it, and found it was the wrong target: BT411's
own reverse-engineering history records that NO gun/arm elevation joint exists
in the authentic engine. The pod's stick-Y aim pitches the COCKPIT EYE and the
weapon boresight directly (mech4.cpp @~5219, pixel-calibrated against real
screenshots) -- the torso geometry never tilts for elevation on this mech
family. Reconstructing a gun-joint binding would have been invented behavior.
- MECH.HPP: EulerAngles eyepointRotation member (out of reservedState, now
[208]) + GetEyepointRotation() accessor.
- MECH.CPP: composed each frame in Simulate -- eyepointRotation =
EulerAngles(Radian(Normalize(lookPitch+elevation)), Radian(Normalize(lookYaw)),
Radian(0)), reading Torso::CurrentElevation() via sinkSourceSubsystem.
lookPitch/lookYaw are 0 until the look-button wave (BTCommitLookState) lands.
Verified: BT_FORCE_ELEV=0.8 -> torsoElev and eyePitch both read 0.349066 (the
authentic 20 degree resource limit) every frame, exact match; neutral -> 0.
Zero Fail. Corrected TORSO.NOTES.md's prior (wrong) "next: gun joints" note.

Reconstructs the shared skeleton-joint resolver and binds the first subsystem
(Torso) to the live skeleton.
- Mech::ResolveJoint(name) (mech.cpp @00424b60): GetSegment(name) -> segment
joint index -> GetJointSubsystem()->GetJoint(idx).
- Verified the JointedMover base streams the full skeleton headlessly:
jointCount=19, 40 named segments (gun joints jointlgun/jointrgun, shoulders,
hip, leg joints jointlthigh..jointrankle). BT_MECH_LOG [skel] summary;
BT_SKEL_DUMP lists every segment/jointIdx.
- Torso resolves + binds its twist joint (ResolveJoint(torsoHorizontalJoint))
and pushes currentTwist onto it via Joint::SetRotation (hinge->Radian,
ball->EulerAngles yaw). The TEST.EGG mech has a fixed torso (horizJoint='',
enabled=0) so its twist path is inert -- correct + guarded, zero Fail.
Next joint piece: elevation -> gun joints (jointlgun/jointrgun, the fixed-torso
aim mechanism) via weapon-joint binding; then gait leg animation. Both are
VISIBLE only under the renderer; headlessly the joint transforms are loggable.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Reconstructs Torso::TorsoSimulation (installed as the Torso's per-frame
Performance) and wires the torso aim into MechControlsMapper::InterpretControls,
so the control surface now covers aiming as well as locomotion.
- TORSO: analogElevationAxis/analogTwistAxis + SetAnalog* setters,
CurrentElevation()/GetHorizontalEnabled() accessors. TorsoSimulation slews
currentElevation += analogElevationAxis*baseElevationRate*dt clamped to the
vertical limits, and (if horizontalEnabled) currentTwist by the twist axis
clamped to the horizontal limits (authentic torso.cpp core; the skeleton-joint
application is deferred with the render wave).
- InterpretControls: routes stick pitch (stick_y, squared) into the torso
elevation every mode; Std/Vet route stick yaw into the twist. BT_FORCE_ELEV
dev hook.
Verified: BT_FORCE_ELEV=0.8 -> the elevation slews up and clamps at the authentic
verticalLimitTop = 0.349 rad = 20deg; neutral -> 0; zero Fail.
Deferred: skeleton-joint application (render wave), HUD free-aim slew,
look/eyepoint commit.

The Mech ctor now reads walkingTurnRate / runningTurnRate / maxAcceleration /
throttleAdjustment from the GameModel resource (SearchList(GameModelResourceType)
-> ModelResource), replacing the bring-up-default constants for those fields.
Each read is sanity-guarded (out-of-band -> keep default) since BT411 flags parts
of the ModelResource layout as mis-decoded -- but the live values came back clean
and authentic: walkTR=75deg/s, runTR=50deg/s, maxAcc=30 u/s^2, throttleAdj=1.0
(walking turns faster than running; maxAcc matches the madcat note), confirming
our reconstructed struct layout is correct for these fields.
Verified: at walk speed the authentic 75deg/s tightens the turn circle to r~6.9
(=speed/turnRate); zero Fail. Still on defaults (pending LoadLocomotionClips):
reverseStrideLength (top speed) / walkStrideLength / reverseSpeedMax -- measured
from the walk/run animation clips.

Installs Mech::Simulate as the mech's per-frame Performance (was DoNothingOnce).
Reconstructs the load-bearing spine of the 1995 Simulate (mech4.cpp @004ab430):
integrate the body velocity into localOrigin (linearPosition.AddScaled(..,
worldLinearVelocity, dt)) and commit the Origin to the world transform with the
engine idiom (localToWorld = localOrigin, per ENTITY.cpp:988 / MOVER.cpp:850).
Uses the NAMED engine base Mover fields (localOrigin/localToWorld/
worldLinearVelocity) -- BT411's MechBaseLayoutCheck proved the WinTesla decomp's
raw this+0x100/0x260 offsets actually stomp those base fields; the clean 1995
build addresses them by name.
- MECH.HPP: Mech Performance typedef + SetPerformance + Simulate() decl.
- MECH.CPP: SetPerformance(&Mech::Simulate) at ctor tail; Simulate body.
Verified headlessly (BT_MECH_LOG "[sim] mech pos=" 1Hz): BT_DRIVE="5,0,10"
advances the mech +5.0/s x, +10.0/s z (y fixed) = exactly the injected world
velocity; no BT_DRIVE -> worldLinearVelocity is 0, mech holds spawn pose. Zero
Fail/Exception either way. BT_DRIVE is a retained dev hook for headless motion.
Deferred (locomotion wave): gait-cycle self-propulsion feeding worldLinearVelocity
(IntegrateMotion->AdvanceBodyAnimation, steered by mapper throttle/turn), heading
integration, terrain-height drop, cockpit telemetry filters.

The world now executes. Entity::Execute only PerformAndWatch's entities in
application state RunningMission, reached by two RunMissionMessages
(WaitingForLaunch->LaunchingMission->RunningMission). The 2nd is dispatched by
Player::ManageApplicationStatus when the launch fade expires -- but that only
runs inside PlayerSimulation, not the launch-phase HuntForDropZone. So the
player must switch Performance onto PlayerSimulation after it spawns.
- BTPLAYER.CPP DropZoneReplyMessageHandler: after CreatePlayerVehicle +
InitializePlayerLink, choose the per-vehicle Performance by class -- Mech ->
SetPerformance(PlayerSimulation)+SetScoringPlayerFlag; else CameraShipSimulation.
- BTPLAYER.CPP PlayerSimulation: chains the authentic base Player::PlayerSimulation
(CalcRanking + ManageApplicationStatus + vehicle-pos copy + status service);
console SCORE-delta flush deferred to the scoring wave.
- SENSOR.CPP SensorSimulation: minimal-safe partial (radarPercent = 1 -
GetSubsystemDamageLevel, sensor healthy) so the roster tick path can't Fail
once RunningMission engages. The heat/electrical gating awaits the power/heat
sim wave (PoweredSubsystem/Generator/HeatSink/HeatWatcher *Simulation staged).
Verified: BT_MECH_LOG run reaches "[tick] roster live (first Sensor frame)",
two RunMissionHandler transitions, zero Fail/Exception. The mech is executed
each frame; its BODY Performance is still DoNothingOnce (real Mech::Simulate =
Phase 5.3, now the frontier).

Phase-5.1 crash solved + two BTPlayer bricks reconstructed. The tree now
builds AND boots end-to-end with no staged Fail() reached, into the running
per-frame game loop.
- EMITTER.CPP: define Emitter::AttributePointers[]/AttributeIndex (ChargeLevel,
chained to Subsystem::AttributeIndex) and point Emitter::DefaultData at it.
EMITTER.HPP declared the index but the .cpp never defined it, so the surviving
PPC.CPP (PPC::DefaultData binds inherited Emitter::AttributeIndex) and
GAUSS.CPP (chains it) captured a NULL activeAttributeIndex -> GetAttributePointer
faulted on the first PPC (roster slot 22). Fix clears all 33 roster slots and
the control-mapping binding block.
- BTPLAYER.CPP InitializePlayerLink: real body -- dispatch PlayerLinkMessage
(our EntityID) to playerVehicle + replicants (mirrors engine
CameraDirector::CreateCameraShip). No staging.
- BTPLAYER.CPP VehicleDeadMessageHandler: non-death flavours (-2 drop-zone probe,
>=0 respawn re-post) delegate to the authentic Player base handler; only the
-1 death cycle stays staged (needs mech4 + scoring roles).
Verified: 516-line smoke run, zero Fail/Exception/abort; boot reaches
LBE4ControlsManager::Execute per-frame, waiting only on absent RIO hardware.

Trace confirms the MechControlsMapper (slot 0) publishes its control attributes
correctly: throttleAttr/controlModeAttr resolve to non-NULL pointers. So the
mapper's AttributeIndex works. The post-construction crash (GetAttributePointer
attr=0x13) is on a DIFFERENT object (EAX heap addr after the mapper) -- a streamed
watcher targeting another simulation, not the mapper. Localizing next. (BT_MECH_LOG
mapper trace retained.)
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
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.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The Mech ctor fully constructs (33 subsystems / 7 weapons on real TEST.EGG data,
trace-confirmed). The crash is the control-mapping resource binding in
MakeViewpointEntity resolving subsystem attribute IDs via GetAttributePointer --
the subsystems publish none (reuse base AttributeIndex). Documented the precise
phase-5 step-1 scope (per-subsystem AttributeIndex + the ID chain) in MECH.NOTES.md.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Live trace (BT_MECH_LOG) on the pod TEST.EGG mech: '[mech] segment walk done:
subsystemCount=33 weaponCount=7' -- the segment walk instantiates the ENTIRE real
subsystem roster (31 subsystems + 2 sentinels, 7 weapons) from the actual streamed
model, no crash. The structural reconstruction is proven end-to-end on real data.
The crash is AFTER full construction, in MakeAndLinkViewpointEntity's attribute-
watcher setup (an AttributeWatcher resolving a subsystem attribute via
GetAttributePointer). Phase-5 frontier confirmed = per-subsystem AttributeIndex
tables + watcher wiring. Trace gated behind BT_MECH_LOG.

Records that the Mech constructor works live (segment walk instantiates the full
roster, mech links as viewpoint, mapper installs) and the precise phase-5
frontier: Simulation::GetAttributePointer via PerformAndWatch, because the
reconstructed subsystems reuse the base AttributeIndex and publish none of their
real attributes. Phase-5 plan (per-subsystem AttributeIndex -> watcher/chain/plug
wiring -> mech2/3/4 per-frame sim -> rendering) in MECH.NOTES.md.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Unrecognised subsystem classIDs now get a base MechSubsystem (Laser/ParticleCannon
-> Emitter) so control/damage bindings that resolve a subsystemID find a real
subsystem, not a NULL plug. This moved the boot PAST the first Link::AddToPlug
NULL-deref; it now runs to Simulation::GetAttributePointer -- the subsystem
ATTRIBUTE system. Each reconstructed subsystem currently reuses the base
Subsystem::AttributeIndex, but the streamed control-mapping / gauge bindings
reference subsystem-specific published attributes (Sensor RadarPercent, Generator
OutputVoltage, Emitter ChargeLevel, ...) that aren't in the base index -> the
attribute lookup walks off the end. Reconstructing each subsystem's AttributeIndex
(+ plug/capability-chain wiring) is the phase-5 integration. BT: 42 ok.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
SetMappingSubsystem installs the control mapper into roster slot 0 (the streamed
control-mapping binds DirectMappings to subsystemID 0). MechControlsMapper ctor
constructs (per-frame InterpretControls deferred to phase 5). With RIO controls,
MakeViewpointEntity now builds the MechRIOMapper, installs it, and gets PAST the
controls check -- the mech constructs AND links as the viewpoint entity. Boot now
advances into the mission-startup / control-binding path (next: a real NULL-deref
there, deeper than the staged Fails). BT: 42 ok.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The Mech ctor now finds the model's subsystem-model-stream resource
(SearchList by SubsystemModelStreamResourceType), wraps it in a MemoryStream,
and walks the segments -- switching on seg->classID to into the base Entity's subsystemArray, caching sensor/gyro/sinkSource/hud
and counting weapons.
KEY FINDING: the source410 VDATA ClassID values MATCH the 4.10 binary for the
core subsystems (0xBBD=Condenser, 0xBC3=Sensor, 0xBC5=Torso, 0xBD6=HUD, ...) --
BT411's 'mislabels' were its OWN wrong enum names. So the walk switches on the
real VDATA names cleanly. Unrecognised classIDs leave a NULL slot (roster stays
aligned) rather than aborting.
LIVE: boot now runs the full Mech ctor -- segment walk instantiates the roster,
no crash -- and advances PAST it to BTL4Application::MakeViewpointEntity, which
halts at 'Mech has no controls mapping!' (the slot-0 control mapper /
SetMappingSubsystem is the next brick). The largest function in the game
executes. BT: 42 ok; tree links clean.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Replaced MECH.HPP reserved[331] with the named Mech-own members: cached subsystem
pointers (sensor/gyro/sinkSource/hud) + messageManager + weaponCount, the 5
capability chains (ChainOf<Subsystem*>), and the embedded status/animation state
(4 AlarmIndicators, Reticle, 3 StateIndicators, 2 SequenceControllers, NameFilter,
telemetryFilter[5]=AverageOf<Scalar>, 3 CStrings) + a reservedState pad for the
phase-5 per-frame fields. The subsystem ROSTER (subsystemArray/subsystemCount)
lives in the base Entity (GetSubsystem/GetSubsystemCount), so the Mech only caches
back-pointers.
The Mech ctor now CONSTRUCTS all embedded members (alarms Initialize'd, reticle
armed, state indicators sized, telemetry filters sized, sequence controllers
Init'd) -- compile-verified -- then halts at the segment walk (the remaining
piece). BT: 42 ok; tree links clean.

Records the full mech-subsystem hierarchy discovered while reconstructing the
roster, with per-class build status. 6 classes done + verified (MechSubsystem,
HeatableSubsystem, HeatSink, PoweredSubsystem, Sensor, Generator); the tree shows
the remaining intermediates (HeatWatcher : MechSubsystem, PowerWatcher :
HeatWatcher) that unblock the Torso/HUD/Gyroscope branch (the Mech's directly-
referenced subsystems), plus Myomers/Condenser leaves and the separate weapon
subtree. The reconstruction pattern is now a proven template (documented). Enables
efficient continuation.

Generator : public HeatSink (classID 0xBC3) -- the voltage SOURCE that
PoweredSubsystems tap (currentTapCount = attached loads). Reconstructed from the
BT411 decomp + the surviving GNRATOR.TCP partial: ctor chains HeatSink, seeds
ratedVoltage/outputVoltage/maxTapCount/startTime/shortRecoveryTime + stateAlarm(5)
= AlarmIndicator, derives generatorNumber from the segment-name suffix. Statics,
dtor, TestClass/TestInstance/ResetToInitialState real (ResetToInitialState mirrors
the .TCP); GeneratorSimulation (per-frame voltage/short) staged. Master-instance
SetPerformance install deferred (per-frame sim staged anyway).
Power system pair now in place: Generator (source) + PoweredSubsystem (load).
Roster classes so far: MechSubsystem, HeatableSubsystem, HeatSink,
PoweredSubsystem, Sensor, Generator. BT: 27 ok; tree links clean.

Sensor : public PoweredSubsystem -- the radar/targeting subsystem, using the
SURVIVING 4.10 interface (CODE/BT/BT/SENSOR.HPP) with a reconstructed SENSOR.CPP
body (from BT411 decomp). Ctor chains PoweredSubsystem, inits radarPercent/
selfTest/badVoltage, and installs the per-frame performance unless the owner is a
replicant (owner->GetInstance() != ReplicantInstance -- the clean form of the
binary's (flags & 0xC) != 4). Statics, dtor, TestClass/TestInstance,
ResetToInitialState, TakeDamage, DeathReset real; SensorSimulation (per-frame
radar) + CreateStreamedSubsystem staged.
Completes the first full vertical slice of the subsystem roster, all
compile-verified: MechSubsystem -> HeatableSubsystem -> HeatSink ->
PoweredSubsystem -> Sensor. The hierarchy backbone is proven; remaining leaves
(Generator, Gyro, Torso, HUD, Myomers, weapons) follow the same pattern.
BT: 27 ok; tree links clean.

Fixes the staged POWERSUB.HPP base (HeatableSubsystem -> HeatSink, the real
hierarchy) and reconstructs PoweredSubsystem: a HeatSink that draws electrical
power. Added members (voltageSource = SubsystemConnection, electricalStateAlarm =
AlarmIndicator(5), modeAlarm = AlarmIndicator(3), input/output/ratedVoltage) and
corrected the resource struct (voltageSourceIndex + thermalResistivityCoefficient
+ startTime). Ctor chains HeatSink and primes the electrical state; statics, dtor,
ResetToInitialState, TestClass/TestInstance real.
The voltage-source resolution (indexing the owner mech's subsystem ROSTER for the
powering generator) + master-instance electrical sim + AttachToVoltageSource are
deferred to the segment-walk phase (phase 4) where the roster is populated -- the
subsystem constructs with no attached source until then. Verified slice now:
MechSubsystem -> HeatableSubsystem -> HeatSink -> PoweredSubsystem. Compile-verified
(BT: 26 ok); tree links clean.

HeatSink : public HeatableSubsystem (confirmed hierarchy) -- a thermal mass with
a coolant loop. Added to HEAT.HPP/.CPP: the class + its SubsystemConnection slot
helper + HeatSink__SubsystemResource. Ctor chains HeatableSubsystem and seeds the
thermal state from the resource (startingTemperature/degradation/failure/
thermalConductance/thermalMass), heatAlarm(3) = AlarmIndicator, heatFilter =
AverageOf<Scalar>(15). Statics, dtor, ResetToInitialState, TestClass/TestInstance
real; the per-frame thermal sim (HeatSinkSimulation/DrawCoolant) staged.
Also reconciled HeatableSubsystem to the 4.10 fields: its resource struct now
carries startingTemperature/degradationTemperature/failureTemperature/
thermalConductance/thermalMass (was the BT411-mislabeled thermalMass/degrade/fail/
coolingLoop set), and degradationTemperature/failureTemperature are base members
(HeatSink reads them). Verified slice now: MechSubsystem -> HeatableSubsystem ->
HeatSink. Compile-verified (BT: 25 ok); tree links clean.

HeatableSubsystem (HEAT.CPP) reconstructed + compile-verified (BT: 25 ok):
statics, ctor (chains MechSubsystem resource form + ResetToInitialState ->
currentTemperature=300, heatLoad=0), dtor, TestClass/TestInstance,
CreateStreamedSubsystem staged. Verified slice now: Subsystem -> MechSubsystem
-> HeatableSubsystem.
Also mapped the roster hierarchy from BT411, which is DEEPER than the staged
headers (recorded in MECHSUB.NOTES.md):
MechSubsystem -> HeatableSubsystem -> HeatSink -> PoweredSubsystem -> {Sensor,
Generator, ...}
Findings for the next steps: (1) HeatSink is MISSING entirely from the staged
tree and must be added between HeatableSubsystem and PoweredSubsystem;
(2) staged POWERSUB.HPP wrongly derives PoweredSubsystem from HeatableSubsystem
(real base = HeatSink) -- fix it; (3) PoweredSubsystem has inter-subsystem wiring
(resolves its voltage-source generator from the owner mech's subsystem roster),
imposing a segment-walk ordering constraint for the phase-4 ctor.

The base all ~30 mech subsystems derive from. Reconstructed against the 4.10
structure per the MECHSUB.NOTES analysis (NOT backdated from BT411's divergent
version):
- Header: expanded with the real mech-specific member set (statusAlarm =
AlarmIndicator, vitalSubsystem, alarmModel, criticalReference,
collisionCriticalHitWeight, printSimulationState, configureActivePress,
resource). Dropped the speculative MessageHandlers static -- MechSubsystem
reuses the base Subsystem sets (inherited Simulation handlers/attrs/statecount).
- CPP: statics (ClassDerivations/DefaultData), both ctors (light name+classID and
resource), dtor, TestClass/TestInstance, and the damage API on the 4.10
per-type model -- GetSubsystemDamageLevel/SetSubsystemDamageLevel read/write the
real DamageZone::damageLevel [0,1]; ForceCriticalFailure; TakeDamage delegates
to the zone. Both ctors build the damage zone the base leaves NULL.
Deferred (documented): the Mech__DamageZone per-type armour STREAM wiring (ctors
use a trivial armour-free base DamageZone placeholder for now) and
CreateStreamedSubsystem (model-load stream format). These are refinements above
the ctor frontier, not boot blockers.
Compile-verified (BT: 24 ok); full tree still links clean. Next: the subsystem
roster (GAUSS/PPC/SENSOR source + .TCP partials + decomp).

Begins phase 2 (MechSubsystem base + subsystem roster) with the base-class
analysis that keeps the reconstruction on the 4.10 damage model. Key findings:
- All base deps survive: Subsystem (SUBSYSTM.HPP + staged SUBSYSTM.CPP),
DamageZone (DAMAGE), Mech__DamageZone + BT damage model (MECHDMG.HPP),
AlarmIndicator (just built).
- Finding 1: the staged base Subsystem ctor sets damageZone=NULL, so the derived
MechSubsystem creates the Mech__DamageZone (BT411's zone-creation is right).
- Finding 2 (CRITICAL): the damage model DIVERGED. 4.10 is per-damage-TYPE --
DamageZone has defaultArmorPoints + damageScale[5] {collision/ballistic/
explosive/laser/energy} and STREAMS its own armour (DAMAGE.CPP:335,413).
BT411 reconstructed a per-FACING armorByFacing[5]/structureReference model that
MechSubsystem hand-seeds -- those fields exist only in BT411's ReconDamageZone
proxy, NOT in the 4.10 zone. So BT411's MechSubsystem ctor CANNOT be backdated
verbatim; doing so would install a damage model the 4.10 engine doesn't
implement, corrupting every subsystem.
Corrected approach (now fully scoped, ready to write): chain base Subsystem,
create Mech__DamageZone, add mech-specific members + TakeDamage override, let the
zone stream per-type armour. Full detail in MECHSUB.NOTES.md; the staged
MechSubsystem__SubsystemResource (per-facing, BT411-copied) is flagged for
re-derivation.

NameFilter is the Mech's mechNameFilter (@0x36c), a small fixed debounce record
the ctor initialises. Reconstructed from FUN_00435a7c: a 10-word (0x28) struct,
Initialize() sets [2]=1 / [8]=[9]=-1 / rest 0 exactly. Header-only. Field
semantics unresolved (only caller is Initialize; reader is the unbuilt HUD) --
names best-effort, but size + init values are binary-exact, which is all the
Mech layout + ctor need.
All 3 missing embedded helper classes now reconstructed + compile-verified under
BC4.52 (AlarmIndicator, SequenceController struct+Init, NameFilter). MECH-LAYOUT.md
step 1 marked done. Next: MechSubsystem base + the subsystem roster, then finalize
MECH.HPP (probe sizeof==0x854), then the ctor + segment-table walk.

The BT keyframe-animation player embedded in the Mech as legAnimation/
bodyAnimation. Struct field layout (from BT411's binary-offset map), default
ctor, dtor, and Init(Mech*) reconstructed and compile-verified; Init is
ctor-time (Mech ctor calls legAnimation.Init(this)/bodyAnimation.Init(this)) so
it's real (binds owner + caches owner->GetJointSubsystem()). The per-frame gait
engine (SelectSequence/Advance/Reset) is staged with Fail bodies -- it fires
only once the mech is ticking, past the current ctor frontier.
BT stage 23 ok; full tree still links clean. Evidence + real/staged split in
SEQCTL.NOTES.md.

Full-archive re-check: AverageOf DOES survive (AVERAGE.HPP, the SIGNATURED
lineage BT411 preserved), so telemetryFilter[5]'s type is available. The
genuinely-missing embedded helpers are just AlarmIndicator, SequenceController,
and NameFilter (confirmed absent from all of CODE; no alarm/filter/sequence
headers) -- to be reconstructed from BT411 decomp before the Mech layout finalizes.

Begins the Mech reconstruction milestone (analysis phase). Extends the existing
MECH-LAYOUT.md worksheet with the findings needed to build MECH.HPP + the ctor:
- Resolved the BT411 mechrecon.hpp proxy layer to real 1995 types (ReconAlarm ->
AlarmIndicator, ReconSeq -> SequenceController, ReconFiltered -> AverageOf<
Scalar>/NameFilter, ReconChain -> ChainOf, ReconMatrix -> AffineMatrix;
StateIndicator/Reticle survive as-is; BTVal mostly base-class pose fields).
- CRITICAL: AlarmIndicator, SequenceController, NameFilter, AverageOf are ALSO
absent from the 4.10 archive -- additional helper classes the milestone must
reconstruct first (their sizes set the embedded-member offsets).
- Subsystem source availability mapped: full (GAUSS/PPC/SENSOR), .TCP partials
(AMMOBIN/EMITTER/GNRATOR/HEAT/MISSILE/PROJTILE/PROJWEAP), decomp-only (rest).
- Key tractability insight: StateIndicator is fixed-size (level count stored, not
arrayed), so a FUNCTIONAL fresh build needs only the right member set/types in
order -- byte-exact offset matching is a later refinement for network wire
format, not required to boot.
- Revised reconstruction order: helpers -> MechSubsystem+roster -> finalize
MECH.HPP (probe sizeof==0x854) -> ctor+segment walk -> per-frame path.
Everything below the Mech ctor runs real reconstructed code; the ctor is the
live frontier (spawn factory validated last commit).

BTPlayer::CreatePlayerVehicle reconstructed (faithful; BT411's BT_SPAWN_XZ/
BT_SPAWN_ENEMY bring-up scaffolding dropped): builds the Mech::MakeMessage from
the mission game-model resource and hands it to MakeAndLinkViewpointEntity.
Mech::Make = new Mech(creation_message); a staged Mech ctor chains the real
JointedMover base (so the model skeleton/segments stream from BTL4.RES) then
Fails.
This validates the entire spawn factory chain live: CreatePlayerVehicle ->
MakeAndLinkViewpointEntity -> registry -> Mech::Make -> new Mech -> JointedMover
base ctor (streams the mech model) -> halts at the Mech ctor (mech.cpp:66).
The Mech ctor (@004a1674, 5690 bytes -- the largest function in the game) plus
the subsystem roster is the next MAJOR milestone, not a brick: it needs the full
1995 Mech member layout derived first (MECH.HPP is still reserved[331]; BT411's
decomp uses raw offset pokes that can't compile fresh), the subsystem class
hierarchy (only GAUSS/PPC/SENSOR survive in the 4.10 archive; the rest are the
measured "917 missing functions"), and the segment-table walk. Plan + scope in
MECH.NOTES.md.

Fixes the incorrect DefaultData reuse of Player::MessageHandlers -- BTPlayer now
has its own handler table (DropZoneReply, VehicleDead, Score, ScoreInflicted,
ScoreUpdate; the last two add BT message IDs) chained onto the base set, matching
the .data table recovered in BT411. A mission-start DropZoneReply now routes to
BTPlayer::DropZoneReplyMessageHandler (the real spawn/respawn dispatch skeleton)
instead of the base "should not be handled by base player class" Fail stub.
Boot ladder now runs the full engine + app + network + mission + player path and
reaches the spawn handshake, halting at CreatePlayerVehicle -> Mech::Make -- the
Mech subsystem frontier (Mech ctor + mech2/3/4 + subsystems + weapons), the next
major reconstruction milestone. Scoring/death handlers, PlayerSimulation, and the
mech-placement tail staged with documented Fail bodies (BTPLAYER.NOTES.md).

Boot ladder advances past player creation. BTPlayer ctor/dtor/Make/
TestInstance/GetExperienceLevel reconstructed from BT411's Ghidra-recovered
body (@004c0bc8) backdated to 1995 idiom; the reserved[38] placeholder in
BTPLAYER.HPP replaced with the real BT-own members.
Key fidelity call: the game-mode flags are derived from
btMission->ExperienceLevel() (the egg's per-pilot experience key) with the
binary-accurate switch rows from the [T1] disassembly -- NOT from the scenario
role's returnFromDeath, which BT411's port uses as a [T3] stand-in. Mapping and
residual naming/[T4] uncertainty documented in BTPLAYER.NOTES.md.
Live boot now runs: banner -> resources -> app ctor -> network single-user ->
egg -> mission -> SetPlayerData -> BTRegistry::MakePlayer -> BTPlayer ctor
(resolves team, seeds experience flags) -> halts at the base
Player::DropZoneReplyMessageHandler stub (BTPlayer's own message-handler table
is the next brick -- DefaultData still reuses Player::MessageHandlers).

The reconstructed tree now produces a runnable binary with the authentic
1995 toolchain (BC4.52 / tlink32 / DPMI32):
- BTL4.CPP main TU reconstructed from the 4.11 Ghidra decomp (FUN_0040109c)
+ the 4.10 binary's own string pool + surviving RPL4TOOL.CPP house style;
probe_main.cpp scaffold retired (BTL4.NOTES.md documents every decoded call)
- L4NET.CPP staged: L4NetworkManager ctor/dtor + 10 vtable-pulled virtuals
(standalone-benign ones no-op, network ones Fail loudly) + NetNub client
globals (Net_Common_Ptr=NULL routes L4File to its plain-DOS path)
- build410.sh: libs now built in the AUTHENTIC makefile member order
(MUNGA.MAK / mungal4.mak / BT.MAK / BTL4.MAK). Order is load-bearing:
tlink emits static-init records in module pull order, and alphabetical
order booted into a null-vptr crash (IcomManager::ClassDerivations
constructing before parent NetworkClient::ClassDerivations). Also fixed
stage_link to the proven 32-bit lib set (SOSDBXC+SOSMBXC, no WATTCPLG)
- BOXTREE.HPP MemoryBlock unify, BTL4GRND notify stubs, remaining engine
backfills (audio/gauge/resource/stream TUs) that closed the deep ledger
Smoke test (DOSBox-X + 32RTM, copy of the pod BT tree, our exe swapped in):
BattleTech v4.10
BTL4Application::BTL4Application
l4net.cpp(22): L4NetworkManager -- l4net.cpp not yet reconstructed
Static init, main, -egg parse, BTL4.RES load (version 1.0.6 check passes),
ApplicationManager and the BTL4Application ctor chain all execute real
reconstructed code; boot halts at the first staged Fail() as designed.
Next brick: the real l4net.cpp body.
