name: Lint (ruff + ty)
# Two things here:
# 1. Advisory diff — ruff + ty diagnostics as a diff vs the target branch.
# Writes a Markdown summary to the run page. Exit zero always.
# 2. Blocking ``ruff check .`` — enforces the explicit rules in
# ``[tool.ruff.lint.select]`` (currently PLW1514). Failure blocks merge.
# Separate job so the advisory diff still runs even when enforcement
# fails.
#
# CI-sensitive file review was previously here as a ``ci-review`` job but
# has moved to ``review-labels.yml`` so it can be rerun independently.

# A refactor that silently removes a public symbol breaks plugins that import it; the Sep 2026
# decomposition opened with 1,703 such drops that reviewers had to find by hand.
# Advisory: it never fails the job. The checkout above is depth-1, so deepen both sides until
# a merge-base exists (the script refuses to report a clean diff without one, by design).
# Diff the PR head ref, not the checked-out refs/pull/N/merge commit: that synthetic commit
# is recomputed server-side whenever main moves, and once it is unreachable no amount of
# deepening ever reaches its parents (run 34285107265: 4 fetches, 4m15s, "no merge-base").

# timeout keeps a step *overrun* off the job-level timeout the same way.
# Sizing: a --deepen=200 fetch took ~56s and a --deepen=1000 ~67s on the runner, and
# main gains ~170 commits/day, so a day-old branch legitimately needs both (~2 min).
