What
Nothing changes in how this works. Tool definitions are only made strict when the remote switch tengu_structured_output_strict is on, and it falls back to off when the server sends nothing. The server returned off both for this site's account and for an anonymous account; no reading has been taken under this release yet.
Why
This is context only. You should see no difference.

This account: off · anonymous baseline: off · compiled default in v2.1.295: off
These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
