#162 4-node retest CAUGHT + FIXED a same-frame double-credit: two lethal deliveries of one salvo (direct + splash, 2ms apart, no sim tick between) each read destroyedAtEntry=0 -- the entry latch samples movementMode 2||9 but our death transition (mode 9 write) ran NEXT TICK in UpdateDeathState, while the binary flips mode SYNCHRONOUSLY inside the same damage pass (its tail gate part_012.c:14761 reads 9||10 already set). Result: duplicate kill credit to the shooter (bench receipts: kills 1->2 in 2ms, awards 525.00/516.67) and a duplicate VehicleDead whose death cycle the receiver dedup swallowed -- but the kill report had already escaped. Invisible to every 2-node bench (direct kills deliver one lethal hit; splash+direct overlap needs crowds) -- the 8-player field 'kills way off' shape. Fix: the death tail now runs the once-per-death transition inline (mode 9 + type-6 + effects) before returning, exactly the binary's sequence; the next lethal message latches on both destroyedAtEntry and deathBlastArmed. The wrong 'synchronous' claim in the old comment corrected. Benches: kd4_bench (receipt-derived per-player invariants + bystander mirror convergence + no-mirror-exceeds-authority + inst=R audit) PASS 9/9/9/9 SWALLOWED=0; kd8_stress staged (8-node all-vs-all melee).

# #162 4-NODE RETEST -- the K/D invariants under bystanders, which the 2-node
# bench structurally cannot see (every kill involved both nodes there).
# A (shooter, autofire missiles) kills B (walker, respawns); C and D are
# BYSTANDERS parked at far dropzones. All 2-node invariants hold, plus:
# I6 BYSTANDER CONVERGENCE: C and D's replicant mirrors (SBMIRROR) reach
# A.kills == kill count and B.deaths == death count -- the #45 record
# is the only way bystanders learn tallies.
# I7 ALL-NODE AGREEMENT: no node ever mirrors a tally HIGHER than the
# authoritative counts (no phantom kills surviving on any pod).
# I8 DELIVERY AUDIT: DMG receipts on the victim are inst=M only -- any
# inst=R delivery is the audit's unmapped replicant path going live.
