# Runs AGENTS.md §3's list, narrowed to what the current change can actually affect: the
# always-tier commands (cheap, no compile -- same three as `main.yml`'s `repo-gates` job)
# unconditionally, then the `rust`/`deps`-tier commands only if the diff against $BASE_REF touches
# that category (`./scripts/lib-changed-paths.sh`, the same categories `main.yml`'s `changes` job
# and `./pre-push` use).
#
# Not part of the normal workflow: once the hooks are linked (AGENTS.md §2), `git commit`/`git
# push` already gate this list automatically (AGENTS.md §3) -- running it by hand duplicates a
# check a hook or CI already owns the result of. This exists for the exception: local tier-3
# confidence (build/doctest/bench/doc/package/deny/public-api) without a CI round-trip, e.g. while
# offline or iterating faster than CI turns around.
#
# Override the base with $1; defaults to origin/main, the same convention
# ./scripts/check-mutation-gate.sh uses. Diffs against the working tree, not just HEAD (see
# lib-changed-paths.sh's changed_paths), so an uncommitted edit is never invisible to this.
