Both reported by the operator on first use of the runbook merged in #55.
Step 1 said `cd infra/ansible && ./site.sh --tags system --limit k3s_prod`.
There is no site.sh anywhere in this repo. It was wrong four ways at once:
this repo drives Ansible with `ansible-playbook <playbook>` and never a
wrapper (playbooks/site.yml is the full bring-up chain, not this); the module
work is in playbooks/node-baseline.yml; targeting here is `-e k3s_hosts=...`,
not `--limit`; and Ansible exists only in the pinned toolbox, with ansible.cfg
read only from infra/ansible. Replaced with the real command plus why
`-e k3s_hosts=k3s_prod` matters (the default group is decommissioned dev) and
why `--tags system` must never be dropped (an untagged run also executes the
`disks` tasks, which assert on prod's deliberate placeholder devices).
Step 2 told the operator to stage the server key at /work/.cache/server.key
"inside the repo's gitignored cache". .cache/ is NOT gitignored -- the file was
ignored only incidentally by `*.key` (.gitignore:11). So the path was safe for
a reason I had not identified, and renaming it (server.pem, wg-server) would
have left a committable WireGuard private key in the checkout, which
no-plaintext-secrets does not recognise. The step now names the real rule,
marks the suffix as the load-bearing part, and gives a check-ignore
verification to run before trusting it.
Docs only -- no manifest and no behaviour change. Touches no sensitive path.
Also records the post-merge measurements for #55, whose own entry predates the
merge: Flux applied ad3f56e by the real path, all 18 Kustomizations Ready,
hostNetwork confirmed (pod IPs are the node IPs), and the designed fail-closed
state (Init:0/1 on the missing wg-server-key Secret).
