`make edit-vault` runs `ansible-vault edit` (decrypt → nvim → re-encrypt on :wq,
abort on :cq) so editing the vault is one step with no plaintext left in the work
tree, then validates structure. `make check-vault` runs scripts/check-vault.py:
decrypts in-memory, asserts valid YAML with secrets under the nested `vault:` map
and no empty leaves, and prints a values-masked structure view (comments visible,
secrets never printed). Both default to the production all-vault; override VAULT=.
Update the vault header comment, CLAUDE.md (command table + Secrets section), and
scripts/README to point at edit-vault (note check-vault.py is the one venv-
dependent helper, by design).
