"""run_edge.py <app> <from-ref> <to-ref> [--sub X] [--keep] [--no-remove]

One app's full walk on guest 9202. Writes everything under
`documentation/audits/update-night-2026-09-21/night-2026-09-23/apps/<app>/`:

    log.txt        every line this run printed, as it printed it
    badges.json    the „Frissítés elérhető" badge in BOTH languages, before and after
    phases.json    every update phase with its timestamp
    observables.json  the four version observables side by side
    verdict.json   `09`'s verdict-record shape

`inconclusive` is never collapsed into `failed`.
