Follow-up to the pve-host Loki shipper (aac807fb). The host reached Loki via an
/etc/hosts pin of the Traefik LB IP — Viktor flagged that as the wrong solution
(no hardcoding; the DNS infra should handle it). Registered loki.viktorbarzin.lan
in Technitium as a CNAME -> ingress.viktorbarzin.lan (the anchor whose A record
auto-tracks the live Traefik LB IP, so it's renumber-proof), via the Technitium
API + zone-sync to all 3 instances. Removed the /etc/hosts pin from the PVE host;
promtail now resolves the name purely via DNS (verified still shipping to Loki).
insecure_skip_verify stays — the internal .lan cert isn't publicly trusted.
Docs (monitoring.md) + the pve-promtail.yaml header updated to drop the pin
references. The DNS record is API-managed (the viktorbarzin.lan zone convention),
not in this repo; auto-managing .lan CNAMEs in technitium-ingress-dns-sync
remains a noted follow-up.

Emo's Claude agent was given root SSH to the Proxmox host (`ssh pve`, dedicated
shared-root key emo-pve-agent@devvm) so he can manage the host — e.g. the R730
fan daemon — through his agent. To keep an audit trail of what that agent does,
and to feed the long-pending Wave-1 S1 security rule, the PVE host now ships its
systemd journal to cluster Loki:
- snoopy logs every execve() to journald (identifier=snoopy), enabled via
/etc/ld.so.preload; config scripts/pve-snoopy.ini.
- promtail v3.5.1 (amd64) ships /var/log/journal to Loki as {job="pve-journal"}
(full host journal; filter identifier="snoopy" for the command audit), and
relabels sshd auth to {job="sshd-pve"} — which ACTIVATES S1 (it was PENDING
only for lack of this shipper). Config/unit: scripts/pve-promtail.{yaml,service}.
S1 won't false-fire on legitimate access: the devvm SNATs through pfSense to
192.168.1.2, which is already in the S1 source-IP allowlist.
Loki is reached via an /etc/hosts pin (10.0.20.203 loki.viktorbarzin.lan);
follow-up noted to register a Technitium CNAME so it auto-tracks LB renumbers.
Host pieces are hand-managed (not Terraform), like fan-control and the rpi-sofia
promtail — these files are the source of truth. Docs updated: security.md
(S1 LIVE) and monitoring.md ("External host: pve").
