continuous-integration/drone/push Build is passing
- secrets/ is now the private cc-ci-secrets repo (submodule). defaultSopsFile path unchanged. - secrets.nix: add wildcard_cert/wildcard_key sops secrets -> path=/var/lib/ci-certs/live/*. - proxy.nix: cert is sops-from-git, not an operator file drop (reframed; FATAL guard kept as decrypt-path check).

# Reverse proxy = the canonical Co-op Cloud `traefik` recipe, deployed via abra in

# wildcard / file-provider mode (wildcard cert as ssl_cert/ssl_key swarm secrets,
|
|
# LETS_ENCRYPT_ENV empty => NO ACME, no DNS token). See DECISIONS.md "Proxy: real coop-cloud/traefik".
|

# Phase-1c: the cert at CERT_DIR is sops-decrypted from git (cc-ci-secrets) at activation
|
|
# (modules/secrets.nix wildcard_cert/wildcard_key), NOT an out-of-band operator file drop.

#

# Declared as an idempotent-RECONCILE systemd oneshot (like swarm-init): it inspects current
|
|
# state and converges every activation/boot, self-healing drift (redeploys if the stack is gone,
|
|
# re-inserts secrets if missing). No run-once sentinel. So a from-scratch install is just
|
|
# `nixos-rebuild switch` + operator preconditions (D8) — no manual post-steps.
