Judge which offered rows one nominated statement retires or replaces.
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
# Judge Group Closure ## Group Closure - A nominated row is a retirement statement when it says that a fact in one candidate row is no longer current, including when it describes that fact as a past preference. - Past tense or a shared topic is not enough. Choose a target only when the nominated row makes the candidate row's present claim no longer true. - Return null when both rows can be true at the same time, including when they describe different strengths of interest or different aspects of one topic. - Treat strength as part of the fact. A past strong preference does not retire a present weaker interest in the same topic. It retires only a candidate that claims the same strong preference is current. - Example: "used to be interested in X" retires "enjoys X" because it says the base interest is no longer current. - Counterexample: "used to really like X" does not retire "is currently drawn to X" because a former strong preference and a present weaker interest can both be true. Return null. - Choose every candidate row whose current meaning the nominated row retires. …

How to install
mdr add sno-ai/sno-station/judge-group-closure@sha256:f89fba979f9c1cd9The line at the top of this page pins the label git:20260909.4a6955e, 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.
