Combat: AUTHENTIC weapon groups -- streamed per-mech button bindings + the real fire chain (task #5)
The recovered system: fire channels = LBE4ControlsManager buttonGroups (0x40/0x45/0x46/0x47); default groups = the per-mech type-6 controls-map resource in BTL4.RES, installed by the T0 CreateStreamedMappings the port already called -- it needed only the TriggerState attribute (id 0x13 PINNED to the binary value; fireImpulse@0x31C is the binary's TriggerState) and an input feed. Keyboard/harness now push press/release edges into the button groups; the gBT*Trigger bypasses, per-type keyboard split and 1,0 pulse hack are retired -- weapons sharing a button fire TOGETHER (madcat Trigger = 4 weapons). Myomers @4b9550/@4b95b8 misattribution corrected (they are MechWeapon ConfigureMappables/ChooseButton). Verified 2-node: kill through the authentic chain (12 hits vs ~36 pre-groups). Config-mode session (regrouping UI) = the remaining stage, KB-scoped. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Cross-pod beams: replicate emitter discharge via subsystem update records
User report: lasers only visible on the window firing them. The peer's replicant emitters never learned the master fired. THE AUTHENTIC PIPE (decomp-verified): - FUN_0041c350 (the "beam keepalive" ServiceDischarge/ContinueDischarge call) does TWO things: queue the LOCAL deferred beam-effect callback (@0x4bac0c) on the app+0x34 manager -- our per-weapon render walk already plays that role -- and set the subsystem DIRTY bit, which maps to the 2007 engine's updateModel / ForceUpdate(). - Replication rides SUBSYSTEM UPDATE RECORDS inside the mech's update message: the roster walk already hands the entity's stream to every subsystem's PerformAndWatch; Simulation::WriteSimulationUpdate serializes each requested updateModel bit; Entity::UpdateMessageHandler routes received records by subsystemID to the subsystem's ReadUpdateRecord. All engine machinery -- the missing pieces were the Emitter's serialize/apply pair + the triggers. CORRECTIONS to the dormant task-33-era transcriptions (never exercised -- nothing ever set updateModel -- so the latent misreads never surfaced): - The weapon-family VTABLE SLOT MAP was swapped: slot 6 = ReadUpdateRecord, 7 = WriteUpdateRecord, 9 = TakeDamage (evidence: Mech hierarchy symmetry + body semantics; @004ba568 resolves an EntityID at rec+0x30 through the entity index -- record semantics, not Damage). Renamed across MechWeapon / Emitter / ProjectileWeapon; the real Emitter::TakeDamage @004bafc8 is undecoded (inherits MechWeapon for now). - Emitter/MechWeapon Write: `*record = 0x38/0x18` is the record LENGTH, not recordID; rec+0x30 is the TARGET's EntityID (GetEntityID()), not a colour -- the old `CopyColor(targetEntity+0x184)` was also a databinding trap. - OVERRIDE-SIGNATURE TRAP: the decls used each class's own shadowing UpdateRecord typedef as the param type, silently NOT overriding the engine virtual (the base ran instead; nothing would ever have serialized). Base-typed params (Simulation__UpdateRecord*), casts inside. - Emitter::ReadUpdateRecord reconstructed (@004ba568): target EntityID resolve (drop unknown non-null targets), MechWeapon alarm apply chain, beam fields. - ServiceDischarge/ContinueDischarge: ForceUpdate() per keepalive tick + one final record at beam end (turns the peer's beam off). - Mech::DrawWeaponBeams extracted from the player-only drive block so the walk runs for REPLICANTS (+ per-mech gun-port cache -- the process-wide statics would have served the player's segment pointers as the replicant's muzzles). VERIFIED 2-node: A fires 57 volleys -> 225 emitter records -> B applies all 225 -> B draws 414 beams (PPC blue / laser red, from A's replicant's own gun ports). Solo un-regressed (150 beams, kill chain, no crash). Also preserved: the full Mech::WriteUpdateRecord @0x4a0c2c recovery (reference/decomp/mech_writeupdate_004a0c2c.disasm.txt) with all 9 record types decoded (pose/alarm/leg-state+heat with the body-channel write-through re-sync, knockdown, death, impact, movementMode) -- transcription deferred; it replicates remote knockdown/death/heat and was not needed for beams.

Three-trigger keyboard weapon groups: 1=lasers 2=PPCs 3=missiles (task #43)
Interim pod-like grouping ahead of the authentic ConfigureMappables/ ChooseButton mapper channels (decomp-anchored in open-questions): - Three fire channels like three pod buttons: gBTWeaponTrigger (lasers, key 1 or SPACE), gBTPPCTrigger (PPCs, key 2), gBTMissileTrigger (missiles, key 3 or CTRL). Keyboard only per user (mouse buttons removed). - EmitterSimulation picks its channel by classID (PPC 3028 vs Emitter 3016); BT_AUTOFIRE holds all three. - The BT_BEAM_LOG sampler modulus 30 aliased to ONE weapon under the new synchronized 5-beam volleys (5 | 30) -> 31 (coprime). Verified: all 5 energy weapons fire (31 samples each), aimed hits land, kill completes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Beams CUT on a destroyed target (the real FUN_0049fb54, was a mislabeled stub)
Answers "can I keep targeting the dead mech?": the lock isn't cleared by anything we've found, but the binary REFUSES to sustain energy beams on a destroyed mech: ServiceDischarge (@004ba8d0) and ContinueDischarge (@004baa20) check the beam's target EVERY discharge frame -- IsDerivedFrom(Mech) then Mech::IsDestroyed (FUN_0049fb54 = movementMode 2||9) -- and kill the beam the moment it dies. EmitterSimulation (@004baa88) applies the same check to the OWNER (a dead mech's own weapons drop everything). Our recon had FUN_0049fb54 as a mislabeled "cockpit/HUD query" no-op stub called with NULL, and never set the beam's target (0x474) at fire -- all three authentic gates were dead. Now: FireWeapon stashes the owner's target entity; both discharge paths + the owner gate run the real check (BTMechDestroyed). Verified: 40 beam samples before the kill, 0 after -- lasers flash-fail on the wreck instead of cutting it like butter (heat is still spent per the binary's FireWeapon, which fires blind; only the DISCHARGE checks the corpse).

gauge wave P1a: publish heat/power/weapon attributes + radar zoom
The gauge-databinding-map workflow found most cockpit gauges resolve NULL because the reconstructed subsystems publish only a fraction of the attributes the config binds. First publishing batch (attribute tables are read-only static data; ids kept a dense prefix from each parent's NextAttributeID): - HeatSink table dense-append: DegradationTemperature/FailureTemperature (the condenser temp-bar warn/max endpoints -- were NULL, so the two-part bars could not scale), NormalizedPressure/DegradationPressure/CoolantMassLeakRate, and the HeatSink link. Condenser/Reservoir inherit this -> all 6 condenser temp bars now resolve current/warn/max (verified: BT_GAUGE_ATTR_LOG all OK). - PoweredSubsystem::GetAttributeIndex() (new) publishes InputVoltage->voltageSource -- the cluster power-branch gate (the power-lamp/generator-voltage/state-lamp sub-branch is skipped when it resolves NULL). Flows to Sensor/Myomers/weapons. - MechWeapon::GetAttributeIndex() (new) publishes OutputVoltage/PercentDone-> rechargeLevel; Emitter/PPC/ProjectileWeapon/MissileLauncher/GaussRifle DefaultData re-pointed at it (they carried an EMPTY default-constructed index -> resolved NOTHING). Verified: the ER MED LASER / PPC / STREAK weapon clusters now render live recharge dials (were blank TEMP/STATUS). - Mech::SetTargetRange un-stubbed (radarRange = range) -> the radar map scale + overlay range readout track the mapper's zoom (was frozen at 1000). - GAUGREND ParseAttribute: env-gated per-binding resolution trace (BT_GAUGE_ATTR_LOG) -- durable diagnostic infra for the wave. Verified DBASE+dev gauges: no startup/gauge-construction crash (dense chain intact), combat un-regressed (TARGET DESTROYED), clusters build with InputVoltage resolving. Remaining config-binding NULLs: HeatSink/AmbientTemperature (aggregate bank, P3) + Searchlight/LightOn (P1b). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

P7: subsystem-tree alarm unification -- the whole PoweredSubsystem weapon/power subtree is byte-exact
The reconstruction modeled the binary's 0x54 AlarmIndicator (FUN_0041b9ec) with undersized
stand-ins (AlarmIndicator==ReconAlarm==4B; HeatAlarm==8B) across the entire subsystem tree, so
every field above an alarm sat at the wrong compiled offset. Retype every such stand-in to
GaugeAlarm54(0x54) and de-phantom each class against its ctor, so the whole PoweredSubsystem
subtree becomes byte-exact. An 8-agent read-only decomp-mapping workflow decoded every ctor
first; then hands-on implementation. static_assert-locked chain (verified vs the raw ctors):
HeatSink 0x1D0
-> PoweredSubsystem 0x31C retype electricalStateAlarm@0x264 + modeAlarm@0x2B8 @004b0f74
-> MechWeapon 0x3F0 retype weaponAlarm@0x350; delete 5 phantom tail fields @004b99a8
-> Emitter 0x478 delete outputVoltage/beamLengthRatio/firingArmed aliases
+ beamHit*/beamColor/beamHitData/energyRampTime phantoms;
retype beamOrientation EulerAngles->Quaternion(16B) @004bb120
-> PPC 0x478 (no own fields) @004bb888
PoweredSubsystem -> Sensor 0x328 (no alarm; 3 own fields) @004b1d18
PoweredSubsystem -> Myomers 0x358 (no alarm) @004b8fec
New systemic bug-class instances fixed (added to the CLAUDE.md checklist):
* alias field - Emitter outputVoltage==inherited rechargeLevel@0x320; beamLengthRatio==
beamScale.z@0x434; firingArmed==inherited useConfiguredPip@0x3E0
* phantom field - MechWeapon segmentReference/pipSegment/hasTarget/targetPoint/muzzlePoint
(past 0x3F0); Emitter beamHitPoint/beamImpact/beamImpactScalar/beamColor/
beamHitData/energyRampTime (binary writes inherited damageData/voltageScale
or the value is a method local)
Non-layout fixes required in the same wave:
* outputVoltage->rechargeLevel also in the compiled GAUSS.CPP:74/93 (external readers of the
removed Emitter field -- must grep EVERY TU, not just the class's own .cpp)
* MechWeapon::GetMuzzlePoint reimplemented faithfully (removed muzzlePoint collided with
Emitter's own fields at 0x3F0) via a BTResolveWeaponMuzzle void* bridge in mech4.cpp,
resolving the weapon's mount segment (inherited this+0xdc) through the owner segment table
* DetachFromVoltageSource fixed to set electricalStateAlarm not modeAlarm (raw @004b0e30
writes the 0x264 alarm)
The vehicleSubSystems aux-screen gauge raw reads (btl4gau2.cpp:868/952 at subsystem+0x2b8/+0x278)
and the Sensor RadarPercent path now read the CORRECT byte offsets (garbage under the short layout).
Verified: combat DESTROYED-in-8, 28 shots, 0 crashes, heat heatEnergy=1.34e7, every static_assert
lock passes, heapcheck-clean through construction (the phase the isolated PoweredSubsystem retype
had overflowed). LESSON: a factory-bridge runtime Check(sizeof<=alloc) does NOT fail the build --
only a static_assert sizeof lock catches alloc overflow at compile time.

P7: byte-exact re-base of the CORE heat leaf (HeatSink/Condenser/Reservoir/Generator/Myomers)
The reconstruction modeled the binary's shared alarm/connection types with undersized
stand-ins, sliding every field above them low (the 72-byte auxScreenNumber gap). Fix the
foundational heat-leaf classes byte-exact + static_assert-lock them, from the ctor decomp:
Shared types corrected:
* SubsystemConnection 4 -> 0xC (binary link node FUN_004af9cf; FUN_00417ab4 derefs +8)
* GaugeAlarm54 = 0x54 (real AlarmIndicator FUN_0041b9ec; STATUS level at +0x14,
so subsystem+0x184 == heatAlarm+0x14 == GetLevel())
WatcherGaugeAlarm now typedefs GaugeAlarm54 (Watcher branch locks stay valid).
Byte-exact + locked (ctor-verified):
* HeatSink heatEnergy@0x158 linkedSinks@0x164 heatAlarm@0x170 resource@0x1C4
pendingHeat@0x1C8, sizeof 0x1D0 (@004adda0)
* Condenser valveState@0x1D0 condenserAlarm@0x1DC (@004ae568)
* Reservoir reservoirAlarm@0x1D0 ... squirtEfficiency@0x22C, sizeof 0x230 (@4aef78)
* Generator stateAlarm@0x1FC, sizeof 0x250 (@004b225c)
* Myomers phantom moverConnection tail removed (fits 0x358)
Three systemic bug classes fixed (added to the checklist in CLAUDE.md / HARD_PROBLEMS.md):
* alias field - a subclass member re-declaring an inherited slot the ctor reuses
(Condenser refrigerationOutput==massScale@0x160; Reservoir
coolantCapacity==thermalCapacity@0x128) -> use the inherited name
* alarm-interior - a value read at alarm+0x14 modeled as a separate member
(HeatSink heatState@0x184, Reservoir injectActive@0x1e4)
-> route to alarm.GetLevel()
* phantom field - a member past the object end (Generator shortFlag@0x25C is really
*(owner+0x190)+0x25c the msg-manager, @004b0efc; Myomers
moverConnection@0x110 a write-only base slot) -> remove it
Heat conduction now reads the REAL heatEnergy=1.34e7 (not garbage); combat DESTROYED-in-8,
0 crashes, heapcheck-clean through construction.
REMAINING (measured; a distinct larger task): making PoweredSubsystem byte-exact grows it
+0x98 and cascades into MechWeapon/Emitter/PPC/Sensor/Myomers -- all model the 0x54
AlarmIndicator with 4-byte ReconAlarm / 8-byte HeatAlarm stand-ins and are short +
phantom-tailed; retyping without byte-exacting them overflows the Emitter alloc (heap
corruption). PoweredSubsystem kept on HeatAlarm(8) stand-ins (marked) pending a
subsystem-tree ALARM UNIFICATION. See docs/HARD_PROBLEMS.md P7.

Initial commit: bt411 -- standalone Windows BattleTech (Tesla 4.10 port)
Clean, self-contained extraction of the BattleTech-specific work from the
reverse-engineering workspace -- engine + game + content + build, with nothing
from Red Planet or the raw archive dumps. Builds green (Win32) and runs the
single-player drive->animate->target->fire->damage->destroy loop out of the box.
Layout:
engine/ MUNGA + MUNGA_L4 shared 2007 engine, carrying our BT render/loader
work (bgfload/L4D3D/L4VIDEO: BSL bit-slice decode, LOD/ground/shadow
models) + image codec; the minimal rp/ headers the audio HAL needs
game/ reconstructed BT logic + surviving-original BT source + fwd shims
+ WinMain launcher
content/ full runtime tree (BTL4.RES, VIDEO/, GAUGE/, AUDIO/, eggs, BTDPL.INI)
docs/ format specs + reconstruction ledgers
reference/ raw Ghidra pseudocode (recon source-of-truth) + decomp exporter
tools/ MP console emulator + map/resource scanners
One top-level CMake builds munga_engine lib + bt410_l4 game lib + btl4.exe.
All paths relativized (186 fwd shims + ~437 CMake abs paths -> repo-relative);
DXSDK is the one external, overridable via -DDXSDK. Verified: builds to a
byte-identical 2.27MB exe and runs combat (TARGET DESTROYED, 0 crashes) against
the bundled content.
