| 1 | //! End-to-end check of audio attachments over ACP (issue #143). |
| 2 | //! |
| 3 | //! Audio works the way images do (see `acp_images.rs`): the capability is |
| 4 | //! advertised for the whole connection and the decision is made per prompt. |
| 5 | //! No cloud tier takes audio (onde-cloud drops `input_audio` parts), so: |
| 6 | //! |
| 7 | //! - a model on the user's own endpoint receives the clip as an OpenAI |
| 8 | //! `input_audio` content part; |
| 9 | //! - an `onde-*` tier is sent text only, with a note in place of the clip, |
| 10 | //! and the user is told the clip was left out. |
