What

When a session resumes, the stored state for a running loop is now parsed and rejected unless the condition is a string and the iteration count, timestamp and starting token count are all non-negative whole numbers. Valid state is truncated before use: the condition to 4000 characters and the last-reason text to 512.

Evidence

tokens_at_start

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
