CydandClaude Fable 5 740ef2b0a7 BT410 Phase 5.3.32: the per-head A/B -- three engineering heads now exact
The gauge framebuffer is PLANE-PACKED: L4GAUGE.CFG gives each port a bit
mask, not a rectangle, so all six heads share the same x/y and are separated
only by bit -- the packing the VDB splits into the pod's physical screens.
Comparing RGB was therefore measuring nothing useful; the "magenta artifact"
just meant the wrong heads were lit at that pixel.

New instruments (emulator/render-bridge/gauge-ab/, with a README):
  planes.py  per-head scoreboard -- shipped vs ours, missing vs extra, per
             port mask, recovering the 16-bit word from DOSBox's RGB565
  BT_VIS_LOG a complete cockpit widget map from the single dispatch every
             gauge widget is built through (MethodDescription::Execute),
             printing name + port + authored position
  ab.sh      stages the fresh build over BTL4REC.EXE and kills any running
             DOSBox before launching -- see below

The fix: the Comm page's pilot roster is the POD roster (the viewpoint mech's
ControlsMapper pilot array, mapper attributes 15/16), not the mission's
player list.  It is zero in a solo mission, so the shipped page draws empty;
ours resolved the local player and painted its icon in colour 0xff.  The gate
belongs in the row source, not PilotList::Execute -- Execute's empty branch
still has to run, because erasing is what the shipped page draws.

  head    shipped    ours   missing   extra          (was)
  Eng1      17981   17981         0       0     (0 / 1030)
  Eng2      17981   17981         0       0
  Eng3      17981   17981         0       0
  Comm      15656   13557      2099       0     (2099 / 1253)
  Heat      21374   20913       566     105     (566 / 990)

Title-band magenta 404 -> 0.  The 2099 Comm pixels we are missing were
missing before the gate, so it is a strict improvement.

Method note, which cost more than the bug: the rig's confs run BTL4REC.EXE
out of the mount while the build writes build410/btl4opt.exe, and nothing
connected the two.  Three measurements ran an hour-old binary, so a change
that "did nothing" three times had never been tested -- and the correct first
hypothesis was discarded on that evidence.  ab.sh now re-stages every launch.
