community.general 12 removed the `yaml` stdout callback, so every ansible
invocation died with a [DEPRECATED] error. Use the core default callback
with `callback_result_format = yaml` — identical output, no collection dep.
CLAUDE.md's access recipe still described the retired `-J kuku … 10.8.0.4`
hop; `mamba` is now an ssh alias over the wg overlay. Also record two things
that cost time on the 2026-09-01 bench session: the vaulted admin password
cannot authenticate over SSH at all (RouterOS refuses password auth for a
user holding an SSH key while always-allow-password-login=no), so each
operator seat needs its own key imported; and the checked-in .venv carries
shebangs from the original /home/sjat path.
