"""Gate: fail if any markdown file breaks the naming convention.
|
|
|
|
Invoked by `scripts/check_md_naming.sh`, which pre-commit calls with the
|
|
staged files. Exits 1 and lists every violation; exits 0 silently otherwise.
|
|
|
|
Two rules:
|
|
|
|
1. Naming -- a markdown file must be README / CLAUDE* / DOCS*.
|
|
2. TODO ban -- no TODO*.md at all. Tasks live in the todo app, not in files.
|
|
|
|
The old "REMOVE ME AFTER FINISH" marker rules are retired with TODO files.
|
|
|
|
The check is deliberately deterministic code rather than a judgement call --
|
|
adjudication belongs in an exit code, not in a model.

The exemption rules are written against full paths ('/.github/'), but

--all walks absolute ones. Matching a relative path against those rules
