Summary
Version 1.18.31 restores model, effort, mode and reasoning-chunk boundaries when sessions are loaded, resumed or forked. It also makes remote configuration authentication failures visible during startup and exits with a failure status.
Why it matters
Reliable state restoration is essential for coding agents that operate across long-running, resumable tasks rather than one-shot prompts.
