Two-tier state architecture:
- Tier 0 (infra, platform, cnpg, vault, dbaas, external-secrets): local
state with SOPS encryption in git — unchanged, required for bootstrap.
- Tier 1 (105 app stacks): PostgreSQL backend on CNPG cluster at
10.0.20.200:5432/terraform_state with native pg_advisory_lock.
Motivation: multi-operator friction (every workstation needed SOPS + age +
git-crypt), bootstrap complexity for new operators, and headless agents/CI
needing the full encryption toolchain just to read state.
Changes:
- terragrunt.hcl: conditional backend (local vs pg) based on tier0 list
- scripts/tg: tier detection, auto-fetch PG creds from Vault for Tier 1,
skip SOPS and Vault KV locking for Tier 1 stacks
- scripts/state-sync: tier-aware encrypt/decrypt (skips Tier 1)
- scripts/migrate-state-to-pg: one-shot migration script (idempotent)
- stacks/vault/main.tf: pg-terraform-state static role + K8s auth role
for claude-agent namespace
- stacks/dbaas: terraform_state DB creation + MetalLB LoadBalancer
service on shared IP 10.0.20.200
- Deleted 107 .tfstate.enc files for migrated Tier 1 stacks
- Cleaned up per-stack tiers.tf (now generated by root terragrunt.hcl)

## Context
Deploying new services required manually adding hostnames to
cloudflare_proxied_names/cloudflare_non_proxied_names in config.tfvars —
a separate file from the service stack. This was frequently forgotten,
leaving services unreachable externally.
## This change:
- Add `dns_type` parameter to `ingress_factory` and `reverse_proxy/factory`
modules. Setting `dns_type = "proxied"` or `"non-proxied"` auto-creates
the Cloudflare DNS record (CNAME to tunnel or A/AAAA to public IP).
- Simplify cloudflared tunnel from 100 per-hostname rules to wildcard
`*.viktorbarzin.me → Traefik`. Traefik still handles host-based routing.
- Add global Cloudflare provider via terragrunt.hcl (separate
cloudflare_provider.tf with Vault-sourced API key).
- Migrate 118 hostnames from centralized config.tfvars to per-service
dns_type. 17 hostnames remain centrally managed (Helm ingresses,
special cases).
- Update docs, AGENTS.md, CLAUDE.md, dns.md runbook.
```
BEFORE AFTER
config.tfvars (manual list) stacks/<svc>/main.tf
| module "ingress" {
v dns_type = "proxied"
stacks/cloudflared/ }
for_each = list |
cloudflare_record auto-creates
tunnel per-hostname cloudflare_record + annotation
```
## What is NOT in this change:
- Uptime Kuma monitor migration (still reads from config.tfvars)
- 17 remaining centrally-managed hostnames (Helm, special cases)
- Removal of allow_overwrite (keep until migration confirmed stable)

Root cause: PMTU black hole on WireGuard tunnel. The tunnel runs over
the HE IPv6 6in4 tunnel (gif0 MTU 1280). With WG overhead (~80 bytes),
effective inner MTU is 1200 — but both sides were configured at 1420.
SSH kex packets >1200 bytes were silently dropped.
Fix: Set tun_wg0 MTU to 1200 on pfSense + peer_855 MTU to 1200 on
London GL-iNet. Re-enabled London DHCP/ARP import in remote CronJob.
All 3 sites now fully automated:
- Sofia: Kea leases + ARP every 5min
- London: DHCP + ARP via pfSense→London SSH hop, hourly
- Valchedrym: DHCP + ARP via pfSense→OpenWRT SSH hop, hourly

- Sofia import (every 5min): Kea leases + pfSense ARP via SSH
- Remote import (hourly): Valchedrym DHCP/ARP via pfSense SSH hop
- London SSH (dropbear) hangs during kex on low-power router — disabled
for now, data imported manually. TODO: lightweight push agent
- Fixed SSH key filename (id_rsa, not id_ed25519) for RSA keys
- No more ping sweeping anywhere — all passive DHCP/ARP data

- CronJob now SSHs to Valchedrym OpenWRT (192.168.0.1) to pull DHCP leases + ARP table
- Parses /tmp/dhcp.leases for hostname + MAC, /proc/net/arp for additional devices
- London still uses ping sweep via pfSense WG tunnel (no SSH access to GL-iNet)
- 6 Valchedrym devices tracked: router, alarm, video, termoregulator, 2 clients

All device discovery now handled by phpipam-pfsense-import CronJob
which queries Kea DHCP leases + pfSense ARP table every 5min.
No active scanning needed — pfSense sees all devices passively.

- New CronJob `phpipam-pfsense-import` runs every 5min
- Queries Kea DHCP lease API (IP + MAC + hostname for all DHCP clients)
- Queries pfSense ARP table (IP + MAC for static IP devices)
- Imports into phpIPAM MySQL: new hosts get inserted, existing get MAC/hostname updates
- Reduced fping scan interval from 15min to 24h (weekly audit only)
- Faster, quieter, gets MACs (fping didn't), gets Kea hostnames
- SSH key (RSA PEM) stored in Vault, synced via ExternalSecret

- CronJob now pulls hostnames FROM Technitium INTO phpIPAM for unnamed entries
(reverse sync: Kea DDNS registers → Technitium PTR → phpIPAM hostname)
- Kea DHCP4 now serves 192.168.1.0/24 via pfSense WAN (vtnet0)
- 42 MAC→IP reservations for all known LAN devices
- Kea DDNS registers 192.168.1.x hosts in Technitium (forward + reverse)
- DHCP pool .150-.199 for unknown devices
- Technitium update ACL extended to include 192.168.1.2 (pfSense WAN)

- CronJob syncs phpIPAM hosts → Technitium DNS (A + PTR records) every 15min
- Queries phpIPAM MySQL directly for named hosts, pushes to Technitium API
- Covers 192.168.1.0/24 LAN (TP-Link DHCP, not Kea-managed)
- Kea DDNS configured on pfSense for 10.0.10.0/24 + 10.0.20.0/24 subnets
- Technitium zones accept dynamic updates from pfSense IPs (10.0.20.1, 10.0.10.1)
- 5 reverse DNS zones created (10.0.10, 20.0.10, 1.168.192, 2.3.10, 0.168.192)

Lightweight IPAM with auto-discovery scanning every 15min via fping.
Replaces disabled NetBox (OOM'd). Uses existing MySQL InnoDB cluster
with Vault-rotated credentials. Cloudflare DNS + Authentik auth.
