# Full-repo, blocking: formatting and lint are 100% clean today, so any
# regression here is new debt — no reason to let it in. ruff replaces
# black+isort+flake8 (one tool, one config — see [tool.ruff] in the root
# pyproject.toml, which every package's ruff invocation inherits by walking
# up the directory tree to find it). Frontend prettier/eslint are just as
# clean today (0 errors — eslint's ~130 remaining findings are all
# warnings, e.g. no-explicit-any, not failures), so they're blocking here
# too rather than living only in flowsint-app's own yarn scripts.

# mypy has ~2200 pre-existing errors across the workspace (real, not fixed
# blindly in one pass — see CI notes). Gating full-repo would be a
# lie from day one. Ratchet instead: block only on files this branch touches,
# so new code is held to the strict config and the backlog shrinks as files
# get touched, without a red CI on every unrelated PR.
#
# "Touches" means semantically, not cosmetically: a repo-wide `ruff format`
# adoption (or any future bulk reformat) diffs every file against BASE_REF
# without changing what any of them mean — if that gets counted as "changed",
# the ratchet degrades into gating the whole backlog on whichever PR happens
# to run the formatter first. A file only counts if re-running ruff on the
# BASE_REF version doesn't reproduce today's content byte-for-byte. Resolve
# the ruff binary once up front and call it directly in the loop below —
# invoking `uv run ruff` per file (up to ~2x per changed file) was flaky,
# occasionally producing a spurious empty result that made a purely
# reformatted file look "meaningful".
