 ## Unreleased
 
+## 0.0.3 — 2026-10-11
+
+- A model's `400` now says what it is about when the text allows (a tool call without its result, a conversation that is too long, an image, the model name, the thinking level); the provider's own text is labelled as such, and the error banner expands when tapped to show it in full.
 - Fixed a chat that kept failing with `400 No tool output found for function call …` (or `No tool call found for function call output …`) on OpenAI Responses models and never recovered, while a new chat worked. A tool call stored as `call_x|fc_y` and its result stored as `call_x` were treated as two different ids, so the history repair deleted a real result and the request went out unpaired on every retry. Calls and results are now matched on the `call_x` part, and the Responses request is checked once more just before sending: a result with no call and a repeated result are dropped, a call with no result gets a placeholder. Ported from OpenMinis 1.14.
 - Device protection (Settings > Permissions, on by default): privileged commands from the agent, `android-root-cli` and the Android tools can no longer write partitions or the system partitions, remove `/data/system`, `/data/misc`, `/metadata` or `/data/adb`, uninstall or disable core system apps, factory-reset or remove user 0. Nothing is asked: the agent gets `DEVICE_PROTECTED: <category>: <target>` and tries another way. Everything else stays open. Refusals are listed under the switch. When `/data` is nearly full the app freezes its own terminals and refuses new bulk writes until space is freed. `android-root-cli partition read` exports a partition read-only.
 - Reasoning items replayed on a Responses conversation are re-serialized to the fields official Codex sends (id, summary, content, encrypted_content) instead of the raw backend object, so extra backend-only fields can no longer cause `400 Unknown parameter`.
