Interactive walkthrough of the move from hibernate/rtcwake scheduling to the
per-minute trigger timer: why the old model broke when the PC stopped being
shut down, the login-fire hole that came with it, the fire window and its
catch-up, and the four-step alarm resolution chain.
Includes a simulator that runs the real _decide() rule, so the window and the
gate short-circuit can be poked at rather than just read about.
