#81: 4-node stress PASS -- 56 overlapping death cycles, zero strands; DEATHS tally exact

Browse Source 
Four simultaneous networked nodes, all dying every ~35s on staggered timers so
respawn handshakes overlap (the field condition that stranded 6 of 8 cycles):
56 cycles, every completed one START->RESET, 0 swallowed / 0 mismatch /
0 discarded / 0 ghost / 0 crash.  Scoreboard: every node's PLAYER_DEAD rows
show deaths=N tally=N in lockstep (13/13/15/15) -- exactly one increment per
death, so removing the duplicate VehicleDead dispatch did not drop the DEATHS
column and the latch release did not double it.  The kill-credit path evaluated
all 56 deaths and correctly declined each self-kill (NOCREDIT self=1); KILLS
uses the separate ScoreMessage path the fix never touched.

content/MP4.EGG: the 4-pilot bench egg (ports 1502/1602/1702/1802, novice).

**Verified (4-node stress, 2026-07-30):** four simultaneous networked nodes, all dying every ~35 s
on staggered timers so respawn handshakes overlap (the field condition): **56 death cycles, every
completed one `START`→`RESET`, 0 swallowed / 0 mismatch / 0 discarded / 0 ghost / 0 crash** across
all four. Scoreboard: every node's `PLAYER_DEAD` matchlog rows show `deaths=N tally=N` in lockstep,
one increment per death (13/13/15/15) — the DEATHS column the comms panel draws is exact; the
kill-credit path evaluated all 56 deaths and correctly declined each self-kill (`NOCREDIT self=1`),
KILLS untouched by the fix (separate `ScoreMessage` path). Bench: `scratchpad/night6/mp4_stress.sh`
+ `content/MP4.EGG`.
**Verified:** solo **17 consecutive death/respawn cycles**, every one `START`→`RESET`, 0 swallowed /
0 mismatch / 0 crash (pre-fix this strands permanently after cycle 1). Two-node MP over a real
network path with cross-machine drop-zone replies: A 11 cycles, B 12, 0 swallowed / 0 mismatch /
