VictoriaLogs' -http.pathPrefix applies to every endpoint, not just the UI, so the elasticsearch bulk path is
/logs/insert/elasticsearch/. It rejected the writes with exactly that message. The other three references
(vmalert datasource, the metrics scrape, the deadman health probe) were already prefixed correctly.

systemd 250-257 refuse to read past boots through journalctl, which made the source config invalid and put
the container in a restart loop with exit 78. The object!() casts were only warnings: inside the err == null
branch VRL has already narrowed the parsed value, so get() takes it directly.

Six containers, all loopback-published, reachable only through the gated diag. host:
victorialogs 30d retention, -http.pathPrefix=/logs so Caddy passes the prefix through unchanged
vector docker_logs + journald -> VictoriaLogs (elasticsearch bulk, the documented path)
victoriametrics 90d, scrapes the four taps that were already live plus the new services
vmalert-metrics 11 metric rules: disk, load, memory, RAID, restart loops, a core container gone
vmalert-logs 5 LogsQL rules: sweep failures, publish-deny bursts, failed bot deploys, cert trouble
alertmanager groups and inhibits, posts to Discord, webhook read from a 0600 file not the config
The deadman (bin/vanguard-deadman.sh, host timer, 5 min) is the part that does not trust any of the above:
curl only, it checks each component answers, that the always-firing Watchdog alert is still arriving through
vmalert -> Alertmanager -> dumpd /heartbeat, and the disks. It reports on change and announces recovery once.
Verified here: failures listed, silence when nothing changes, disk threshold, recovery fired once.
Collection uses the Docker socket (Phase 13 option A, chosen explicitly). That is root-equivalent on this host
and is recorded as such in vector.yaml with the two upgrade paths.
