- Add storage.WriteFileAtomic (temp + rename) and storage.CopyFile helpers
- Convert all 8 production config writers to atomic writes: config/state.yaml,
dnsmasq, nftables, domains, wireguard (config + secrets + peers + wg0.conf),
tunnel/cloudflared
- Add sync.Mutex to Reconciler to serialize concurrent Reconcile() calls
triggered by domain registration goroutines
- Add state.yaml backup (.bak) before every write; LoadState falls back to
backup if primary is corrupted
- Reconciler refuses to use empty config on corruption (only on first run
when no state file exists yet)
Extract the Central networking functionality from wild-cloud/api into
a standalone service. Wild Central manages DNS (dnsmasq), gateway
(HAProxy), firewall (nftables), VPN (WireGuard), TLS (certbot),
security (CrowdSec), and DDNS — all the network appliance concerns.
All Cloud-specific code (instances, clusters, nodes, apps, backups,
operations, kubectl/talosctl tooling) has been removed. The API struct
and route registration contain only Central endpoints. Tests updated
to match the new API signature.
Builds and all tests pass.
