--watchdog SECONDS sets the run's watchdog from 1800 (the default, unchanged) to 7200 s; above 1800 the boot preflight requires the A16 on AC. --session (with --console) leaves the guest trigger out of SNAP_EARLY_STOP, so the kext never requests its first-present stop and a desktop session lasts until the watchdog, the thermal guard or tools/request-stop.py. --early-stop-delay is checked against the run's watchdog. tools/test-session-watchdog.py covers the default, the bounds, the delay check and the session's triggers.

"""--watchdog and --session for installed-fresh desktop runs (tools/cycle_lib/installed_fresh.py).
|
|
|
|
The default stays the 1800 s watchdog with the kext's first-present stop. --watchdog admits 1800..7200 s, and the
|
|
boot preflight then requires the A16 on AC. --session drops the guest trigger, so the kext never requests a stop and
|
|
the run ends at the watchdog, the thermal guard or a host stop. No hardware is touched.
