MEASURED our compiled BTPlayer layout (new one-shot [layout] ctor diagnostic): sizeof=652 (0x28c) killCount@0x270 pad_0x280@0x274 objectiveMech@0x278 deathPending@0x284 The three target-designation sites wrote RAW at pilotArray[0]+0x284 intending the BINARY's objectiveMech. On our object 0x284 is deathPending -- the death-cycle latch. So EVERY target designation (the Comm bank 0x30-0x37, or the typed t/y/u/i/o keys) stored a Mech pointer into deathPending, and a non-zero deathPending makes VehicleDeadMessageHandler take its dedup early-return, which skips the warp, ++deathCount, the PLAYER_DEAD record AND the drop-zone hunt. => designating a target silently disabled your respawn for the rest of the process. That is #57's missing first cause: it explains David's very first death being swallowed with no prior death, and the 3-of-3 swallowed deaths in the final round. It also explains the operator's persistent observation that the trouble began when the comms panel went live -- before the pilot list populated, there was nothing to designate. And the designation never worked either: the value never reached objectiveMech (input-audit finding #1). FIX: all three sites now use named-member bridges in the complete-BTPlayer TU -- BTPilotSetObjectiveMech / BTPilotObjectiveMech / BTPilotVehicle / BTPilotPosition / BTVehicleDestroyed. Also retires the raw +0x1fc (playerVehicle) reads and the raw +0x100 position reads in ChooseNearestPilot, and routes its destroyed-check through the real Mech predicate instead of the Is_Destroyed stub. LAYOUT LOCKS: static_asserts on objectiveMech@0x278, deathPending@0x284, killCount@0x270 and sizeof==0x28c, in the friend fn BTPlayerLayoutSelfCheck, so a member shift fails the BUILD instead of silently clobbering the latch again. Rigs: scratchpad/commstest.py (drives designation + captures panels), valvetest.py, lampgallery.py (428-bitmap gallery for #48 visual search).

"""#48 solo reproduction: drive the COMMS panel's target-designation path.
|
|
|
|
The one comms action never exercised in any rig. Target designation (typed
|
|
t/y/u/i/o, and the Comm bank buttons 0x30-0x37) performs three RAW writes at
|
|
`pilotArray[0] + 0x284` (mechmppr.cpp:1344/:1364/:1420) intending the binary's
|
|
`objectiveMech`. Our compiled layout differs from the binary's, so that write
|
|
lands on whatever member really sits at byte 0x284 -- the ctor now prints the
|
|
real offsets, and this run hammers the designation keys while capturing frames.
|
|
|
|
Also toggles the pilot list's SELECT-TARGET highlight, which is the branch that
|
|
makes PilotList::DrawMechIcon repaint (filled box / inverted blit).
|
|
|
|
Kills only the PID it spawns.
