The composer already uploaded an image, split its data URL and put the bytes on the wire as `images`. Nothing on the server read them. The `chat` ClientMessage had no such field, and the prompt reached the sidecar as a bare string, so all the model ever saw was the client-generated `[Attached image: …]` placeholder — a label describing a picture it was never shown. The transport was never the obstacle: `query()` consumes an async iterable of user messages whose `content` is an Anthropic `MessageParam`, and only `pushTurn` hardcoding a string kept it to text. So `images` is threaded through the four hops that dropped it and turned into native image content blocks at the end, renaming `mediaType` to the API's `media_type` at that last step.
