Unclear Nothing shows what switches this verification on, so it is unclear when it applies.

What

A subagent is a helper agent that Claude starts to work on part of a task, and its transcript is the record of what it did. Claude Code can now be set to require that a subagent transcript which was not written on this computer is fetched and verified before it is loaded.

Why

This can affect sessions you resume or sessions run remotely, where subagent history is shown but was recorded elsewhere.
