The v6 app-port relay preemptively bound [::]:<port> for ALL catalog
ports, even apps not installed. Installing such an app (grafana:3000,
photoprism, uptime-kuma, jellyfin — framework-pt 2026-07-27) then hit
'address already in use' from the relay, which triggered
cleanup_stale_pasta_port -> -> killed archipelago
itself (it held the port) mid-install. The daemon crash-looped and the
half-created apps were rolled back and vanished.
Two fixes:
- relay only bridges a port that a running app already answers on over
IPv4 (probe 127.0.0.1:port first) — an uninstalled app's port is never
held, so its install sees a free port and never triggers the cleanup.
- cleanup_stale_pasta_port excludes our own PID from both the ss-based
kill and the fuser kill, so freeing a port can never terminate the
daemon even when the relay legitimately holds it (reinstall case).
