Fault runs

Scripted runs over the recorded feeds: a fault is injected at one step and a scripted operator tries to approve through the same checks the console uses.

Delayed weather

Aspen Acres · set 2026-09-26-r2

The NWS station stops reporting. Its last reading ages past the limit while every other feed keeps updating, then a new report arrives.

The fault is simulated; the snapshot, briefing and decision checks are the real code.
