User-reported 2026-09-16 during the M-154 re-run build: the aim-mode
crosshair no longer renders, suspected to come from earlier v0.3.0 work.
Explicitly parked ('don't fix, just for context'). Entry records the
symptom, rules out the probe-only M-154 commits and D295's menu-buffer
widen, points at the crosshair draw path (crosshairimage / bondview.h
show-hide flag / gunfire.c D215 renderdata family) and a bisect plan.
