Fix deployed to .198+.228, vaultwarden stops clean (no regression). But validation
showed the gate failures are multi-caused: (2) fedimint crash-looping/unhealthy on
both nodes can't be stopped; (3) host-listener repair watchdog restarts
port-unreachable containers fighting stop; (4) gate waits for 'stopped' but apps end
'exited'/'absent' (Exited->Stopped conversion key mismatch); (5) grace vs 60s
gate-timeout (electrumx 300s); (6) .228 contamination. Documented + re-sequenced
NEXT STEPS (fedimint health is the new top blocker).
