Writing down the rule a group was actually enforcing

Takes the decisions a group has already made — the posts it took down, the calls it let stand — and works backward to the rule it was in fact applying, written out in a form a person can read: a scored table of telltale phrases, or a named list of norms. That written rule is the point of the exercise; it becomes the group's operative standard, the thing a human or a model is then held to when the next case arrives, and it can be checked and argued with because it is explicit. Being explicit also lets each rule be sorted by how far it reaches — enforced platform-wide, shared by a cluster of similar groups, or peculiar to one — so a group's own line is separable from everyone else's. The accumulated record ends as a rulebook, not as a classifier.
