- sops-nix flake input, age + ssh-to-age in devShell, .sops.yaml with
per-host recipients (real pubkeys still TODO until lars bootstraps).
- nix/modules/gebos-secrets.nix centralises per-host secret subsets and
renders /run/secrets/gebos-env via sops.templates. Service modules now
read EnvironmentFile= from services.gebos.secrets.envFile instead of
the placeholder /etc/gebos/secrets.env.
- Falls back to a writeText env file when nix/secrets/secrets.yaml is
absent, so `nix flake check` and first-boot eval work pre-bootstrap.
- nix/secrets/README.md walks through age key + sops bootstrap.
- Dev defaults: ingester binary falls back to local tcp/postgres URLs,
process-compose adds mosquitto and wires GEBOS_MQTT_BROKER /
GEBOS_POSTGRES_URL / GEBOS_POSTGRES_PASSWORD + VITE_SUPABASE_URL /
VITE_SUPABASE_ANON_KEY, frontend defaults to 127.0.0.1:8000 in DEV.
