arcattackandClaude Fable 5 63b168cb92 SeekVoltageGraph: full reconstruction -- the eng-page POWER graph + top-box eraser (Gitea #11) 
The #10 audit's one WRONG: the port Execute was a bring-up no-op, so the
emitter/myomer engineering pages never erased their top data box -> stale
sibling-page ghosts on the shared Eng bit-plane (SYSTEM 10 PPC showing the
Streak ammo box, etc).  Full faithful widget landed:

- btl4gau2: ctor/BecameActive/Execute/clear/ticks/cursor recovered from the
  capstone disasm of @004c6798/@004c6920/@004c6934/@004c6be4/@004c6c30/
  @004c6c6c (Ghidra dropped every x87 arg).  Plot: v=0..12000 step 1200,
  x=Round(response(v)*230), y=Round(v*(1/12000)*187) (ld80 @004c6bd0/@004c6d74
  = exactly 1/12000); change-test samples the response at 12000V vs the 9999
  activation sentinel; XOR op for tick/cursor move-by-redraw; destroyed branch
  centres edestryd.pcc and revives via own vtbl+0xC (BecameActive, slot 3 of
  PTR_0051a1fc -- vtable-dump verified).
- The vtbl+0x3C sampler identified from the binary vtables: Emitter slot 15
  @004bb42c = sqrt(P(v)/2.0e8), P @004bb3f4 = damageFraction*v^2*0.5*
  energyCoefficient; Myomers slot 15 @004b8f94 = sqrt(AvailableOutput(v)*3.6/
  350).  FUN_004dd138 == sqrt (part_015.c:4026): myomers' fabs reading
  corrected, GetSpeedReading renamed SeekVoltageResponse.  Port dispatch via
  complete-type bridges BTSeekVoltageSample/BTMyomersSeekSample +
  BTSubsystemDestroyed (databinding rule).
- Emitter's AUTHENTIC attribute table recovered (binary @0x511dd4, ids
  0x1D-0x25) and published: Laser*/Seek*/OutputVoltage@0x414 (currentLevel,
  RAW volts -- the live-cursor feed).  Field renames per the table:
  0x3F8 minSeekVoltageIndex / 0x3FC maxSeekVoltageIndex (static_assert-locked).
  The MechWeapon 0x1D OutputVoltage PORT ALIAS retired (binary table ends
  0x1C; Find walks lowest-id-first, the alias shadowed the authentic row).
  PPC::DefaultData -> Emitter::GetAttributeIndex().
- mech4: BT_PRESET_HOLD=<n> (freeze the #9 preset cycler after n pulses) for
  steady-state pixel verification; BT_SEEK_LOG diag.

Verified live (BLH, autofire): both #10 repro pairs held ghost-free for
minutes (SYS09->SYS10 PPC, SYS02->SYS04 ERMed, SYS05->SYS06 Myomers); curves
draw with live cursors; one replot per activation; quad panels/J-K-L/sec
panel un-regressed.

arcattackandClaude Fable 5 092408041c Cockpit: the CONFIG-MODE weapon-regrouping session + the live-play fire fixes (tasks #6+#11) 
TASK #6 -- the pod's in-cockpit weapon regrouping, fully reconstructed and
live-verified (hold-configure -> tap fire button -> toggle membership ->
release-commit):
- MechWeapon handlers id 9 ConfigureMappables @004b9550 / id 10 ChooseButton
  @004b95b8 (binary table @0x511860; the old "Myomers fns" mislabel swept)
  + the GetMessageHandlers() accessor chain through Emitter/ProjectileWeapon/
  MissileLauncher/GAUSS/PPC (empty per-class sets swallowed dispatch).
- Mapper vtable truth: +0x38 EnterConfiguration / +0x3C ExitConfiguration /
  +0x40,+0x44 AddOrErase evt/dir.  No "secondary vtable @0050f498", no
  "CreateTemporaryEventMappings" virtual (RP-name drift; swept incl CLASSMAP).
  L4 Enter/Exit rebuilt complete: StartMappableButtonsConfigure (the
  NonMapping 0x10000 <-> Mapping 0x8000 mode flip + the gauge's active-weapon
  latch) + the held-button re-arm + the 4 fire-button temp maps; only the RIO
  mapper implements the toggle (Thrustmaster no-ops = can't regroup).
- MechSubsystem +0xE8/+0xEC corrected to controlDestination/controlMessageID
  (ex hostEntity/subsystemId2 mislabel); MechWeapon ctor defaults the
  destination to &fireImpulse (@004b99a8).
- ConfigMapGauge state loop reconstructed (PE-recovered DAT_00518eb4 table;
  buttonGroup GetMapState sampler -- the "needs ModeManager" guard rationale
  was wrong).  Finding [T1]: the shipped binary NEVER enables this gauge (no
  SetColor caller) -- authentically dormant; BT_CONFIGMAP=1 is the dev enable.
- Dev harness: HOLD 'G' opens the session (BT_CONFIG_SLOT picks the weapon);
  BT_CONFIG_TEST scripts a headless verify.  @004afbc4 corrected to its real
  Fail-trap body (the guessed AddOrErase(NULL) body would corrupt groups).
- Bonus [T1]: the binary MechWeapon ATTRIBUTE table has ELEVEN entries
  (PercentDone..WeaponState) -- "TriggerState is the only one" was wrong.

TASK #11 -- the user-reported live-play regressions (both real bugs):
- PHANTOM FIRE: the mech4 bring-up shot block painted an explosion at the
  victim on its OWN 0.3s cadence whenever fire was held -- desynced once the
  authentic recharges landed.  Retired (the real impact visual flows from
  each discharge via the messmgr SubmitExplosion).
- WEAPON BRICKING (the "cuts out" bug): the Loading->Loaded snap window
  (+-0.01 around seekV) assumes the pod's LOCKED 60 fps; one port dt-spike
  jumps it, the byte-verified >1.0 clamp (_DAT_004ba830=0) zeroes readiness,
  and the weapon sticks in Loading at level ~10000 forever (observed live).
  Fixed with pod-frame (1/60s) sub-stepping of the binary's own Loading tick
  -- also fixes the I^2R integral over-heating generators on big steps.
  NEW GOTCHA CLASS recorded: reconstruction-gotchas #12 (frame-pacing trap).
- Duty-cycle measured (max-rate autofire): generators equilibrate in the
  degradation band (recharge stretch ~3.5-4.4x), the FailureHeat breaker
  never trips solo, PPCs sustain ~11.8-damage full-charge fire.  The slow
  kill pacing and recharge gaps are the AUTHENTIC heat economy; the pilot's
  counters (this regrouping UI, generator reassignment, coolant valves) are
  the reconstruction queue.

arcattackandClaude Opus 4.8 070af409f7 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).

arcattackandClaude Opus 4.8 7b7d465e5e 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.
