Fixture exercising the prefer-headers rule across its boundary cases.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fixture **Config**: a line-start bold label should flag. - **Item**: a list-item label should not flag. 1. **Step**: a numbered list-item label should not flag. A sentence carrying **inline bold**: should not flag mid-sentence. ```md **Fenced**: a bold label inside a fenced block should not flag. ```

How to install
mdr add bendrucker/claude/prefer-headers@sha256:2062a4e465543e92The line at the top of this page pins the label git:20261006.a882371, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
