payload_scan_mid.py scans a mid-mission frame (snapfull1, cmd 19,889): identical 9 coordinates as cmd 735 (65.5/72/181/236, all x[66,236]). So cap7 redraws the same static surface patch every frame across its whole length -- no terrain, no battle, ever. Corrects the earlier "mid-mission frames have battle scenes" guess: a full battle scene lives in a different capture entirely. Readout last-mile updated. The decode + array render fully account for cap7's content. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

"""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."""
