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: 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.
All knowledge docs (architecture, runbooks, references, audits, policies)
have been migrated to community.turnsys.com as wiki topics in the VP
TechOps category. Discourse is now the canonical source of truth for
documentation; git edit history no longer serves as the doc changelog.
37 .md files converted to short pointers linking to their Discourse
topics. AGENTS.md updated with new documentation workflow policy.
Code (scripts, configs, playbooks) remains authoritative in git.
Each component README now links to its corresponding Redmine tickets
(closed for completed work, open for pending items) for bidirectional
traceability between code and system of record.
