Unclear What the clean-up removes from the error text is not settled.

What

When Claude Code fails to start a session that runs in the cloud, it used to pass the server's raw error text straight on. It now cleans that text up first. If the cleaned version differs from the original, the original is written to the log with a note that it was not shown.

Why

Raw error text from the server no longer lands on your screen as is, while the full message is still kept in the log for anyone diagnosing the failure.
