What
Claude Code has a failsafe timer that forces a session to shut down if it doesn't close normally in time. When this timer is armed, Claude Code now also records the exact timestamp (failsafeFiresAtMs) at which it's set to fire, in addition to the timer itself.
Why
This is an internal bookkeeping change that makes it possible to know exactly when a pending forced shutdown will occur, which helps with diagnosing shutdown-related issues.
