the REVERSE DISABLED voice (#78): SimulationState 3/4 IS the trigger -- mirror the gimp level into the engine cell

Browse Source 
User + old-timers were right; the earlier "no voice exists" verdict was wrong.
The authored mech audio has state watchers on Entity.SimulationState==3/4
(the binary's one-cell mech+0x40) that start sequence notes 29,16,40 -- two
klaxon hits then Warnings01 zone 8 (key 40-41) = the "reverse disabled"
voice line the testers remember.  The port's cell split (graphicAlarm vs
engine simulationState, gotcha #23) meant the trigger value never arrived.

- mechdmg: mirror gimp 3/4 into SetSimulationState at the leg-half crossing
  (guarded: never stomps disabled/fall/dead states).  Voice verified playing
  end-to-end on the bench: SetupPatch bank2 patch113 note=40 ->
  Warnings01_z7.wav.
- mech.cpp: BT_GIMP_SAFE_BASE_READ on all seven Simulation::ReadUpdateRecord
  sites -- gimp is monotonic per life; a record captured pre-gimp must not
  stomp the cell (the loopback otherwise perpetuates the stale value and
  restarts the warning on every damage event).
- diagnostics (all env-gated): [statefire]/[startreq]/[animind]/[gimp-sim]/
  [simstomp]/[indstomp] + StateIndicator::DebugAudioWatcherCount + raised
  spatial-log caps.  These traced the whole chain and PROVED no SetState
  path stomps the cell.

OPEN (follow-up): a RAW writer (bypasses SetState entirely; invisible to the
indicator-level trap) resets the cell between damage events -- under the
bench's 1 Hz metronome harness it restarted the sequence before the 1.8 s
voice note; sporadic real-play damage is unaffected (one edge -> full
sequence).  Needs a cdb write-watchpoint session; candidates: a recon raw
+0x2c-equivalent write or a struct copy spanning it.

Also decoded en route: the AnimationState triggers on the limp states play
EngineShiftRev01 (the downshift foley) -- working, and NOT the voice.

// #78 GIMP-MONOTONIC RECORD GUARD: the binary's mech+0x40 is one cell, so its
// records always carried the live gimp level (3/4). The port's mirror write
// (mechdmg) can be STOMPED by a record whose simulationState was captured
// pre-gimp -- and the loopback then perpetuates the stale value forever
// (write captures the stomped 1, read re-applies it): the "reverse disabled"
// voice sequence restarted on every damage tick and never reached the voice
// note. Gimp is monotonic within a life, so a record carrying <=1 while the
// live state is 3/4 is stale by construction: patch the RECORD field to the
// live value before the base read -- SetState then dedupes (no edge, no
// restart) and the next WriteUpdateRecord captures 3/4, converging the loop.
