A private out-of-repo maintainer tool turns adopted human review feedback
into candidate skill updates. Only the resulting SKILL.md diff enters this
repository through normal PR review; the tool source, adapter binaries,
provider credentials, and scheduler stay on the maintainer's machine to
keep this repository focused on shipped product code. Kept in proposed/
until end-to-end verification against master lands a candidate PR; the
acceptance criteria list the exact observations that unlock promotion.
