What

In headless sessions (runs without the interactive screen, such as scripted use), Claude Code processes some events at the start of each turn. When those are still running after their time limit, Claude Code now records a cut-off marker before showing its existing warning.

Why

This is diagnostic information only and does not change how the session behaves.
