STEP 1 -- target any peer mech: DONE + verified. A live-mech registry
(BTRegisterMech/BTDeregisterMech from the Mech ctor/dtor) collects
every mech -- player, dummy, and peer replicants. The boresight
world-pick walks BTGetTargetCandidates (all mechs != shooter, closest
ray hit) and the whole fire/damage block retargets from the solo
gEnemyMech to the picked hotTarget; missile/projectile validation
generalised via BTIsRegisteredMech. Verified one-box: instance A
enumerates B's mech as a live ReplicantInstance (20 zones, ownerID=3).
Solo un-regressed (pick->damage->kill clean, 28 hits + DESTROYED).
STEP 2 -- cross-pod damage: dispatch + engine reroute are CORRECT and
invoked with a valid owner, but the dispatched message doesn't reach
the master. Entity::Dispatch (ENTITY.cpp:244) reroutes a replicant's
msg via application->SendMessage(ownerID,...); BT_MP_FORCE_DMG proves A
dispatches at B's replicant with ownerID=3, yet B takes 0 STEP-6
damage. Corrects the KB's [T3] "Dispatch already reroutes": the reroute
FIRES; the break is downstream in the transport/delivery of a
dispatched entity-message (update records flow fine -- net-rx works).
Next MP task = that wire delivery. Diagnostics BT_MP_LOG /
BT_MP_FORCE_DMG retained.

One-box smoke test re-run on the current build: console egg -> mesh ->
RunningMission both instances, 174+ x144-byte update records each side,
2 mech trees per instance, 0 crashes (~6 min). The movement-replication
milestone is intact after all the targeting/weapon/death changes.
Gap map to a first playable LAN fight recorded in
context/multiplayer.md (wiring order): (1) generalize the world-pick
from gEnemyMech to all peer mechs; (2) exercise the Dispatch reroute
for cross-pod TakeDamage; (3) victim state visuals on the shooter's
screen (zone replication or a death event); (4) cross-pod beam visuals
via the AUTHENTIC beam-keepalive messages (FUN_0041c350, templates
@0x511e6c/78 -- already stubbed in emitter.cpp); (5) 2-window driving +
DEATHS scoring; respawn deferred to the P5 teardown debt.
