#118 alarm dig complete: the TechStatus bit model -- MarkGeneratorOut bridge removed
The gauge-alarm "condition" is a STATUS-FLAG BIT INDEX edge-scanned by MechTech (bit 0/1 structure, 2 leak, 3 heat, 4 AmmoBurning, 5 Jammed, 6 !HasVoltage). Conditions 4/5 -> the engEject flash = the AMMO purge/unjam invite (flashing the very key whose streamed function is EjectAmmo) -- never pilot eject; cond 6 -> the bus-switch invite; the PANIC lamp is the sole pilot-eject indicator. The destruction->stateAlarm(4) bridge is REMOVED as unfounded: alarms never read stateAlarm; state 4 is the THERMAL BREAKER state produced by GeneratorSimulation itself (byte-matched vs FUN_004b1f7c). And the binary's crit distributor (@0049c9a8, read raw) touches nothing electrical -- a generator destroyed in place keeps stale Ready voltage until any transition recomputes output via (1 - damage) x rated. The port now matches that subtlety exactly (verified: single-gen force-kill -> no bus invite, no arm, silent unarmed keypad -- all authentic). KB: the full bit table + invite semantics + electrical subtlety recorded in decomp-reference. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
