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.
