Three things that would not have scaled to 70 roles:
- The Python and Ansible dependency pins were about to be copied into every
role. They now live once in molecule-shared/, which scenarios reference
relatively, so they cannot drift apart.
- The helper container images used for probing were hardcoded inline. They
are pinned once in molecule-shared/vars.yml, carry `# renovate:`
annotations, and a custom manager in .github/renovate.json keeps them
current - verified with a local Renovate dry run, which offers
curl 8.11.1 -> 8.21.0 and python 3.13 -> 3.14-alpine. Seventy invisible
hardcodes is the blindness class we have been removing elsewhere.
- Running a scenario meant knowing the venv and cd incantation. `just
molecule <role>` does it, and with no argument lists the roles that have
a scenario.
Molecule is deliberately not wired into prek: a run takes minutes, pulls
images and needs Docker, which is fine on request and not fine per commit.
docs/molecule-testing.md covers how to run and write these, including the
four things a role here needs that a standalone role does not. AGENTS.md
points at it rather than carrying the detail.

Points AI coding agents at the new style guide and summarizes the
repository layout and the conventions that are easy to get wrong
(roles/galaxy being auto-managed, group_vars wiring boundaries,
variable deprecation).
