The binary's one mech+0x40 IS Simulation::simulationState, which rides EVERY
update record header -- so in 1995 a peer's replicant learned the gimp level on
every packet and its gait limped with no gimp-specific replication anywhere.
The port's Mech::PerformAndWatch wrote SetMovementMode(1) every frame ("ground,
non-death, non-airborne"), which erased the level once it was mirrored in for
the warning voice (#78): the wire carried 1, bystanders walked while sliding at
limp speed, and the voice sequence restarted on every damage event (1->4 edge
per tick) instead of announcing once.
- mech4: that per-frame write now writes the AUTHORITATIVE level
(gimped ? 3/4 : 1) via a new alarm-only bridge BTMechGimpAlarmLevel -- which
deliberately never consults the cell it feeds, so a respawn-cleared alarm
cannot re-latch stale gimp out of it.
- BTMechGimpLevel: falls back to the replicated cell, with ONE-CELL precedence
(a fall/death/limbo state wins, so the normal drivers and their death latch
run -- what the binary's single cell enforced structurally).
- Reverted the #78 record guard: on a replicant the master's records are
authoritative, so pinning 3/4 against them would keep a peer limping through
a respawn. Fixed at the writer instead.
- [simstomp] trap now scoped to the watched mech with a module-relative return
address (symcrash-able) -- that is what named the writer.
- Also learned + recorded: zone damage levels replicate only when the EXPLOSION
TABLE's tier is crossed (peer measured at 0.428 vs master 0.857), so peer-side
damage state must never be inferred from them.
Verified two-node (scratchpad/night6/mp_skate.sh): the observer's replicant gets
sim=4 and its gait runs 23 -> 25 (wgr entry -> ggl limp cycle). Field clue that
cracked it: "after respawning a peer DID see the limp" (epilectrik/SAURON).
