Analyzer run-length floor landed

The F154 caveat (analyze_log false-GREENed Asteroids' 313-of-1800-frame run) is closed. GenericExitCheck in analyze_log.py — generic, runs for every console — now parses both REFORGE: headless mode -- N frames max (requested) and REFORGE: clean exit after M frames (completed) and emits FAIL when M < N, echoing any NATURAL-EXIT diagnostic lines into section 1.

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