A new rateLimitGraceActive boolean field has been added to the session state schema (marked @internal). It tracks whether the account is currently in the usage-limit grace zone, as observed from extended-request response headers. The field is described as observation-lagged — it stays latched when extended requests stop and should be expired via resetsAt rather than waiting for a clearing event.
Infrastructure added; the header parsing and state tracking are live (see rate limit grace window under New Features), but rateLimitGraceActive as a schema field is documented as internal.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
Read once, for one account on one subscription tier, against v2.1.217. It isn't a statement about your account. What a flag value here can and cannot tell you
A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
