"""Decisive test: does a MID-MISSION cap7 frame carry a full battle scene (terrain)?
Restore snapfull1 (cmd 19889, paused mid-draw) and scan payload-region writes the same
way. If screen coords spread across x[0,832] there IS terrain to render; if they cluster
or are absent, cap7's mid-mission draws are empty and full-battle frames need another capture."""
