`sops` reads `.sops.yaml`, sees the filename ends in `.sops.yaml`, and
encrypts every value under `stringData` for your age public key. Open the
file afterward — the keys (`api-token`) stay readable, the values are now
unintelligible ciphertext with `sops` metadata appended. That's what's safe

`sops` reads `.sops.yaml`, sees the filename ends in `.sops.yaml`, and —
because of that file's `encrypted_regex: ^(data|stringData)$` — encrypts
only the values under `stringData`, for your age public key. `apiVersion`,
`kind`, and everything under `metadata` (name, namespace) stay in plain
text on purpose: Kubernetes object names have to be plain DNS-safe
strings, and encrypting them would produce a `SopsSecret` that fails to
apply at all. Open the file afterward — `stringData`'s values are now
unintelligible ciphertext with `sops` metadata appended; everything else is
still readable. That's what's safe to commit.
Once pushed and synced, the operator finds this `SopsSecret`, decrypts it
using the private key mounted from step 2, and creates an ordinary
