- Fixed whitespace-only tool output (for example a bare `\r\n` from bash) being sent as-is to OpenAI Completions, OpenAI Responses, and Google providers; it now uses the same placeholder as empty output, since some providers reject whitespace-only tool content with a 400 ([#8720](https://github.com/earendil-works/pi/issues/8720))
- Fixed automatic retry not triggering for gateway upstream failures such as `upstream_error: Upstream request failed`, `upstream_stream_read_error`, and `Upstream HTTP/2 stream failed` ([#10920](https://github.com/earendil-works/pi/issues/10920))
- Fixed automatic retry not triggering for `stream disconnected before completion` errors relayed by proxies that wrap the Codex CLI ([#11057](https://github.com/earendil-works/pi/issues/11057))
- Fixed OpenAI Responses deferred tool loads rewriting the top-level tool list, and losing the prompt cache, on every load after a tool removal. Models with `additional_tools` now declare all tools in `additional_tools` items, starting with one at the head of the input, so removals (announced as text) and redefinitions no longer rewrite the prefix. Tool search and Kimi tool messages rewrite the top-level tools once per removal or redeclaration and keep later loads anchored ([#10940](https://github.com/earendil-works/pi/issues/10940))
