Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent.

How to install

Latest version
mdr add martineserios/thebrana/pre-mortem@v1.0.0

mdr add martineserios/thebrana/pre-mortem@sha256:78d14315ce9f6d60

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
