Gap-analyzes the tailnet Linux fleet + static network gear (switches,
router, APs, PDU, stor1, Reston VPSes) against Uptime Kuma ping
monitors over the socket.io API, and can create missing monitors with
--add. Websocket transport is forced because the Cloudron proxy drops
engine.io polling pushes. First run closed the last 4 gaps: 84/84.

pfv-bms and tsys-umbrel were renamed in the Tailscale admin console,
so MagicDNS now serves the canonical names. The audit key switches
from the OS-reported hostname to the admin-assigned DNS name, which
retires the alias table. Reston VPS exclusion keyed to its MagicDNS
name (tsys-cloudron). Every in-scope system now passes: VM name,
DNS name, and Tailscale name all agree.

Names verified matching (netbird TS/DNS) — no fleet access audit
needed, same treatment as the other Reston systems.

Device-side hostname, /etc/hosts, and Tailscale node renamed from
ultixfield to ultix-field to match the DNS canonical name (convention
match with ultix-streaming/ultix-offstage). Verified unprivileged path
is the ultixfield account with passwordless sudo.

With UCS and Jetson keys in place every auditable system now passes:
68 OK / 2 by-design (Home Assistant, Umbrel). Zero failures.

3dscanner has been offline ~7 months; sandbox is a disposable
break-fix VM rolled back via Proxmox snapshots, so a failed SSH
probe there is expected noise, not a finding.

era stlpc uses root, pfvsvrpi is localuser not subodev [#446]
Probed root access on every host where localuser failed: all Proxmox
appliance VMs (PDM/PMG/PBS), stlpc-artroom/garage, pfv-jetson-nano-1,
and ultix-field accept root key auth; pfvsvrpi takes localuser with
passwordless sudo. Audit now models this correctly — 65 of 74 green.

Exclude the Reston prod VPS (tsys-cloudron-new) from all future audits,
mark Home Assistant and Umbrel as by-design no-SSH appliances, and query
Technitium directly (dig @netinfra-01) instead of getent so local
/etc/hosts entries cannot produce false mismatches. Drops aliases made
obsolete by the sectestbed-hfnoc-uisp rename.

Reusable audit over every Linux tailnet peer: knel.net DNS resolution vs
Tailscale IP, Proxmox VM-name match, expected-user SSH login via the
remote.sh/remote-dns.sh chokepoints, and passwordless sudo verification.
First run (2026-08-26): 54/74 peers fully green, report on Discourse #312.

Previous sessions used `qm guest exec` to back-door SSH keys into ~30 VMs,
bypassing sshd's audit trail in an ITAR/CMMC environment. Wire the ban deep
so it cannot recur:
- tests/remote.sh: remove the vm-guest mode + qm-guest-exec path entirely
- scripts/check-rules.sh: rule #11 fails on any `qm guest exec` / `vm-guest`
pattern in code (scans .sh/.bash/.py; docs may describe the ban freely)
- AGENTS.md: codify "Access-channel policy: SSH only" as non-negotiable;
add "Questions" rule banning harness question tools (use questions-v1.md)
- tests/vm-validation.sh: drop guest-agent key re-injection; SSH-only
- proxmox/perf/scripts/perf-matrix.sh + deploy-tuned-guests.sh: convert
guest-agent execution to SSH (vmroot) now that VMs have key + sudo
- bootstrap-all.sh: re-target the 8 remaining locked-out systems with
correct users/methods; print a console one-liner for publickey-only Pis
Guest-agent remains installable/checkable for Proxmox state visibility —
never as an execution or key-delivery path.

Add __pycache__/*.pyc to .gitignore and remove the tracked bytecode
file. Add version control instructions to AGENTS.md for future sessions.
