Unclear What this check is used to change or gate is not stated in the finding.

What

A new isUnwatchedRepl check was added in two places:

  • The app's base-settings startup gate, where it combines a background-session check with a teammate-agent-id check
  • The launch-arming policy's refusal checks, where it's consulted alongside an existing armed-session check

Why

This lets Claude Code recognize when a REPL session is running unattended and factor that into decisions about whether the session should be ended as if a launch refusal had applied.
