Names real technology throughout (Vault, Authentik, pfSense,
firewalld, Wazuh) instead of staying generic, adds a 'why this
approach vs the alternative' section to every doc, cross-links
heavily between docs instead of treating each system in isolation.
Names real technology (Technitium) instead of staying vague, adds
explicit cross-links to every other system that actually depends on
DNS, explains why self-hosted DNS was chosen, and adds a 'what I'd
improve' section. Template for redoing the rest.
Completes the docs/ set - all 16 systems now have a full deep-dive
page in the diagram+callout+table style. Architecture overview covers
the 4 trust boundaries and 2 traffic planes; IaC pipeline is a fresh
Packer->Terraform->Ansible writeup replacing the stale old-content/
snapshot; disaster recovery covers the 3 independent backup layers
and the deliberately decoupled OS/app upgrade systems.
Completes the orchestration/registry/content batch - Kestra's
check-pause-approve-apply pattern, the self-hosted build pipeline,
the SOC dashboard's 14-source aggregation, the cron heatmap, and the
in-progress content pipeline, all in the diagram+callout+table style.
Mermaid diagrams up front, GFM alert callouts for key decisions and
gotchas, tables instead of bullet walls - replaces plain prose with
the visual template established for security-monitoring.md.
Secrets & PKI, Secret Distribution Model, SSO & Identity,
Firewall & Network Segmentation, DNS Naming Model, and Security
Monitoring - the first batch of per-system write-ups linked from
the new README, sourced and sanitized from the internal KB.
