name: file length

# The 250-line cap, enforced on push as well as in pre-commit
# (refactor_claude_todo.md, "make it permanent").
#
# Unlike the pre-commit hook, which only sees the files in a commit, this runs
# over the whole tree: the hook keeps a violation from being *introduced*, and
# this keeps one from surviving a path the hook never saw (a merge, a push
# from a machine without hooks installed, a rebase that resurrects a file).
#
# No paths filter on purpose. The cap applies to every file in the repo, so
# scoping this job to a subdirectory would be the one way to reintroduce the
# problem it exists to catch.
