Hosts opt in via /etc/snmp/lmsensors-zone-types (one zone type per
line, e.g. Jetson GPU-therm); each type renders its own zone-<type>
chip block so HA templates anchor on the chip name. Default behavior
unchanged; no snmpd restarts (extend re-execs per poll).
Idempotent in-guest tuning: sysctl profile, fq/bbr, THP->madvise with
boot persistence (yields to tuned), fstrim.timer. First applied to
pfv-k8s-wnode-tsys3.

Founder rule: every Technitium/DNS/DHCP change ends with a same-session
SoR sync — zone-snapshot.sh then drift-check green, then commit. Added
the tool (tar-pulls the DZ store from the primary via the chokepoint),
wrote the rule into AGENTS.md (DNS change discipline + Key Scripts rows),
refreshed 4 stale snapshots (knel.net, 1/3.168.192 reverse, 119.70.100
— incl. the deleted ultix-offstage PTR). drift-check: ALL IN SYNC.
Also: last tsrouter mentions retired (AGENTS.md, setup.sh header).
Founder ruling 2026-09-02: ultix-offstage is retired. Removed the host
block (bc:24:11:1f:9d:83 -> 192.168.3.79) from both SoR confs and deployed
to the live pair serially with health gates; failover reports both-normal.
A record + PTR deleted from Technitium both nodes; #307 inventory rows
annotated. Tailscale device removal is a founder console action.
Founder ruling 2026-09-02: tailscale-router retired, subnet routing now
pfv-netinfra-01/02 (both advertise 192.168.0.0/22 + exit routes, verified).
Drop dead tsrouter alias from the chokepoint script; setup/verify now use
the primary as production source; refresh verify record list (tsys-nsm is
also a dead name; add tsys-wazuh CNAME + tsys-siem).
archive/KNELServerBuild copies left as read-only history by design.
Leftover unstaged state from the parallel 09-02 sessions: delete
questions-v1/v2, HomeAssistant/needfromcharles.md, night-grind-plan.md
(content lives in questions-09022206.md / questions-v3.md / git history);
drop superseded UniFi API-key ask (#619 multicast fix made it moot).
Details: https://projects.knownelement.com/issues/344#note-3911
The required-files check pinned questions-v1.md, which breaks every time
the Q&A file versions up (v2 was closed out by the parallel session,
leaving nothing matching). Now glob-accepts any version. questions-v3.md
restores the file; active question channel is ~/PTKR.md per founder.

ntp.conf captured (nodes byte-identical); 171 Technitium DZ zone files
captured from the primary; drift-check now covers dhcpd/pihole/ntp on
both nodes plus a zones md5-manifest check. Live run caught real drift:
node-02 dhcpd.conf was a stale primary copy missing the #614 minisplit
reservation — reconciled git->02 with dhcpd -t gate, serial restart,
failover "Both servers normal", all 7 checks in sync. Red-green unit
tests extended (gen_manifest, tracked-file invariants).
Results: https://projects.knownelement.com/issues/630#note-2
New "Cloudron" group (id 277); all 55 app monitors moved there
(canary-verified). Deleted IP-literal monitor id=8 (dup of DNS-named
id=210) and repointed appletv monitor to new DNS name
stl-appletv-livingroom.knel.net. Fleet-wide IP literals in Kuma: 0.
Sync tool default group updated to 277.
Results: https://projects.knownelement.com/issues/435#note-5
55 http monitors added under "Cloud Systems" (blue/green: canary first,
verified green); 9 root-level strays re-homed into founder's groups
(root now zero). New tools: inventory (read-only dump), cloudron-sync
(idempotent diff/add from committed app list), regroup (lib-based moves;
raw editMonitor times out on this build). fleet-sync now requires
--group-id so it can never place monitors at root again.
Results: https://projects.knownelement.com/issues/435#note-4
- cnodes 102/705/603 moved to TS5-SSD storage by founder (etcd apply 4-5s -> <1s)
- wnode-tsys5 slot retired; ultix-streaming joins in its place (5 workers)
- ultix-offstage unreachable; stays excluded until back on tailnet

Live proof: ecobee answers unicast mDNS with PTR only
(_hap._tcp.local -> "Main Floor._hap._tcp.local"), so the old
replace-on-probe wiped learned records every cycle. Merge by
(name, type) instead. CONFIG_PATH now env-overridable for tests.
