Visual-evidence pipeline was broken corpus-wide: screenshots written to a shared CWD and read stale

prove_loop.run_headless launched the exe without cwd, so the generated runtime's frame_NNNN.ppm writes landed in whatever directory prove_loop was launched from — every corpus ROM overwrote the same repo-root set, and the per-ROM build/Release/ dirs that console_loop globs for visual evidence never received fresh screenshots. The classifier then silently read months-stale files (Pac-Man's "screenshot evidence" dated April 9; Asteroids' May 23)…

Raw traces, ROM material, local paths, and personal data are not part of this public record.
