The merged subset feature failed test-lint: a .py under scripts/, a local parents[N] PROJECT_ROOT, a direct yaml.safe_load, an uncached read, and narration comments.
- move scripts/meta/resolve/pr/subset_roles.py -> cli.meta.ci.subset_roles (scripts/ is .sh-only); dispatcher invokes it via python -m
- parse via utils.cache.yaml.load_yaml_str; import utils.PROJECT_ROOT
- test invokes the module via -m against real roles; nocheck the tempfile read
- strip narration comments; docs document HOW not WHY

The maintainer-only manual CI dispatch (workflow_dispatch) cannot be triggered by fork contributors. The 🧩 Subset label closes that gap: when present on a PR, the detect-affected-roles job resolves the deploy whitelist from an explicit roles: YAML block in the PR body instead of the diff, giving fork PRs the same narrowed matrix a maintainer would dispatch manually. Without the label, behavior is unchanged (the dispatcher falls through to the diff resolver, output byte-identical).
- subset_roles.py: parse and strictly validate the PR-body roles block (invalid YAML / empty / unknown id / path-traversal all hard-fail)
- pr_affected_roles.sh: single dispatcher selecting subset vs diff resolver
- entry-pull-request-change.yml: wire the label and PR body into the job
- PR templates, pipeline/workflows docs and READMEs, integration tests
