Read-only research capture seeding the D-137 credential matrix. Nothing built;
the five D-137 forks remain unruled.

FINDING 1 (qualifies the premise that creation points are already known):
`grep -rnI "ssh-keygen" .` returns ZERO hits repo-wide -- no mkpasswd, pwgen,
uuidgen, random_password or tls_private_key either. Yet the manifests declare
six SSH keypairs plus the OPNsense root password/hash, whose only provenance
record is a manifest COMMENT. Twelve standing credentials therefore have no
reproducible mint. If the jumphost is rebuilt, no repo artifact says how to
recreate them -- a Roosevelt-transfer defect, not merely hygiene. Consequence
for the design: mint-ref must admit three provenance kinds (script:line,
runbook:step, operator-terminal), and the operator-terminal rows are the debt
the matrix exists to surface, not parse errors.

FINDING 2: three credential DIRECTORIES sit outside the SEC-009 per-site creds
convention and outside creds-audit entirely -- the Vault init directory (5
unseal shares + root token), the Octavia PKI directory (8 artifacts including
two CA private keys), and the per-tenant directories. All are named in
CLAUDE.md, so they are known; they are simply uncontrolled. Materially extends
SEC-023. Also flags overlays/octavia-pki.yaml, which lands a CA key blob plus a
plaintext passphrase inside the repo clone, gitignored -- with SEC-004 the repo
still PUBLIC.

FINDING 4 corroborates SEC-020 independently: phase-4 runbook:128 mints the
juju-<dc> superusers with no --password (stored nowhere), and
site-headend-install.sh:452 uses --password in argv.
