 - **Icon sync: correct prefixed model IDs** — `_sync_model_icons()` now discovers the pipe's `function_id` via `type(self).__module__` and writes DB records with the full prefixed ID (e.g. `openrouter_pipe.openai/gpt-4o`) matching what Open WebUI's frontend requests at `/models/model/profile/image`
 - **Streaming status event** — the "done" status event is now correctly emitted at the end of streaming responses (async generator wrapper replaces sync generator that could not `await`)
 - **Dead provider-icon code removed** — `info.meta.profile_image_url` was included in model dicts returned by `pipes()` but Open WebUI ignores all fields except `id` and `name`; the field has been removed in favour of the new DB-sync approach
+- **`pipes()` response always closed** — added `finally: response.close()` to guarantee HTTP connections are returned to the session pool in all code paths (auth errors, JSON decode failures, unexpected exceptions)
