What
The internal description of the rate-limit grace signal changed: the latched flag now clears either when a response reports no grace usage or, if the response named the grace window's reset time, once that time passes on the local clock.
Details
The text also newly states that while the flag is set, an overage status of allowed or allowed_warning means paid extra usage covers the overflow and nothing is cut off.
Evidence
While set, overageStatus allowed / allowed_warning means paid extra usage covers the overflow (nothing will be cut off).
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
