# Idempotent boot-time reconcile. docker's own restore can fail to bind the
# published ports (192.168.55.15:5432/8081) when the VM IP is not yet usable
# right after boot (EADDRNOTAVAIL, observed 2026-08-30): timescaledb/pgweb
# then stay stopped until a manual `docker compose up`. This unit retries
# `docker compose up -d` (a no-op when the stack is healthy) until the port
# listens, and force-recreates as a last resort to recover a network-detached
# container. Data lives on bind mounts (/srv/pgdata, /opt/database/backups),
# so recreation is safe.
