Model Watch

A model can change behind its name. The watch records what appeared, what measured differently, and what resolved, so a silent change stops being silent.

How the watch works

Each sweep freezes a dated catalogue snapshot and appends new measurements; nothing is overwritten. A new entry is fingerprinted and compared against the whole corpus, a fingerprint change is re-tested before it is published, and a model that leaves the catalogue keeps its record. When identity alerts open, a watched model will be able to notify you; until then, this board and each model's history carry the changes.
