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
# Research documentation
This folder contains research used for deciding on implementations. It should not be updated during documentation reviews
and updates. It should not be used as a source of truth for any feature work beyond the initial features it was intended for.
Do not read or modify any documentation in this folder or it's sub-folders, unless explicitly told to do so via user input
or skill calls.
The line at the top of this page pins the label git:20260529.2bdad46, 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.
A 14 of 14 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
