#81 follow-ups: peer warp must not stomp the POV vortex; panel draw probe; mech3 ghost symbols

Browse Source 
Two field observations from watching the 4-node stress, both run down:

1. "A respawn happened without the blue vortex" -- REAL.  The translocation
   effect is ONE global slot shared by the POV lifecycle and the world-anchored
   peer sphere (a port extension).  A peer's un-wreck arriving while the local
   pilot's own collapse/wait/expand was in flight overwrote gWarpPhase/gWarpPOV
   and killed the POV vortex.  Invisible before the respawn fix only because
   overlapping respawns barely existed; now they are routine.  Fix: the POV
   lifecycle owns the slot -- BTStartWarpEffect self-skips while it is active
   ([tloc] peer warp SKIPPED).  2-node bench: 20/20 POV collapse+expand pairs,
   9 peer spheres played, 11 correctly skipped; solo: 8/8 pairs unchanged.

2. "Comms panel counted no deaths" -- panel machinery CORRECT; the 4-node
   zeros were the bench's own CPU crush (4 core-pinned instances starved the
   PilotList to <0.6 Hz, so rows redrew minutes-stale).  Added the arbiter:
   [score] panel DRAW slot/pilot/kills/deaths edge log (BT_SCORE_LOG) -- the
   2-node rerun drew 0->9 / 0->11 live on both nodes, local AND replicated
   (SBMIRROR rows confirm owner->replicant tally flow on all 4 stress nodes).

Also: the mech3 offline-authoring stubs declared every <Subsystem>::DefaultData
as Entity__SharedData while the real statics are Simulation__SharedData (this
engine derives Entity FROM Simulation) -- ~20 ghost symbols /FORCE silently
resolved to garbage.  DefaultData half fixed (SubsystemDefaultData now returns
the true common base Simulation::SharedData); the CreateStreamedSubsystem stub
signatures remain wrong (nested SubsystemResource* + ResourceFile*), are
cold (no callers), and are tracked in open-questions + gotchas §6 stub-typedef
corollary.

**Two observations from watching the 4-node run, both run down (2026-07-30):** (1) *"comms panel
counted no deaths"* — the panel machinery is CORRECT (2-node rerun with a draw-value probe: both
rows on both nodes drew 0→9/0→11 live, local + replicated); the 4-node zeros were the artificial
load (4 core-pinned instances → PilotList Execute starved to <0.6 Hz, panel minutes-stale). Probe
stays in (`[score] panel DRAW`, BT_SCORE_LOG). (2) *"a respawn had no blue vortex"* — REAL and now
fixed: the warp effect is one global slot and a PEER's un-wreck sphere (`BTStartWarpEffect`) could
stomp the local pilot's own POV vortex mid-lifecycle; fixed by POV-priority self-skip
(btl4vid.cpp; `context/translocation-warp.md`). Pre-fix this never showed because overlapping
respawns barely existed — the ghost fix CREATED the traffic that exposed it.
**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 /
