Operator correction: secrets are kept in source through sops. #55 shipped the WireGuard server private key as a Secret to `kubectl create` by hand. Two real costs, not just a convention break: * R-SEC-01 / spec docs/07 -- secrets live in source, SOPS-encrypted, and reach the cluster only through Flux. * It broke DR for the one credential that cannot be re-derived. A rebuild restores everything in git; it does not restore a hand-made Secret, and losing this key means re-enrolling EVERY device, because each client profile pins its public half. #55 papered over that with "keep a copy in your password manager". (Note secret-provenance did NOT forbid the original shape -- it scopes to app-namespace=true and vpn-ingress is deliberately a platform namespace. The rule broken was the written requirement, not an enforced control.) An agent still must not mint a long-lived private key (CLAUDE.md §6), so the file is committed ALREADY ENCRYPTED with `privatekey: REPLACE-ME`. That makes the wiring complete and green from the first commit -- resource line plus both overlay decryption patches -- leaving the operator exactly one act: replace the value. A commented-out resource to uncomment later is the "in git, no generator entry, reviewed, merged, still broken" shape this repo keeps hitting. The init guard is now a validation rather than an emptiness check: the value is piped through `wg pubkey`, which accepts only a real curve25519 private key, and the pod names which case it hit -- placeholder, empty, mangled, or (the silent one) still `ENC[` ciphertext because an overlay is missing its decryption patch, which otherwise applies cleanly with every Flux condition green. Second, independent finding that also fixes #55's step 2: `wg` is on the HOST only and `sops` is in the CONTAINER only, so `sops -d | wg pubkey` cannot run in one shell -- the command #55 documented could not have worked. Every step is now split by where it runs, and the written key is verified by comparing sha256 digests rather than printing anything. `qrencode` is on neither, so the QR step says so and gives the install command. Touches clusters/** and adds a **/*.sops.yaml, so approval-policy will block pending the operator's /approve-override. Deliberately not posted by me.
