Package health implements the mandatory health gate for aa-server-status servers: a single GET request whose 2xx response is the sole authoritative "serving" signal (design/aa-server-status.md §6.1 stage 3, §7.1).

Package lifecycle implements the common child-launch machinery shared by every server type — process-group isolation, per-server environment overlay, and log-file management — plus the two launchers whose command shapes need no further logic (mlx, exec).

Package observe is aa-server-status's observation layer: it answers "what is actually running" without ever killing or launching anything.
