 - Fixed Mistral streams being aborted mid-generation (e.g. during long thinking) after the request timeout; the timeout now applies only to waiting for response headers ([#10609](https://github.com/earendil-works/pi/issues/10609))
 - Fixed a symlinked `AGENTS.md` in a git worktree nested inside its main repo causing no project context file to load ([#10681](https://github.com/earendil-works/pi/issues/10681))
+- Fixed the code mode tool description claiming every failed tool call rejects; a tool that declares an output schema resolves with its value on failure too (e.g. `bash` with a nonzero exit)
