# Roadmap: Producer Upload Deferred Work

The producer HTTP upload package plan has been implemented for the current
server and client scope. Current behavior is documented outside roadmap files:

- [Source bundle contract](../integrations/source-bundle.md)
- [HTTP upload contract](../integrations/http-upload.md)
- [Operations](../operations.md)
- [Development policy](../policy/development.md)

This roadmap records producer-upload extensions that are intentionally not part
of the current implementation.

## Deferred Work

- Durable idempotency records across server restarts.
- Producer coordination integrated with a database-backed queue.
- Durable client queues or background producer workers.
- `UploadAndWait` or long-polling helpers.
- Run cancellation, retry, or listing endpoints.
- Zstandard-compressed tar archives.
- Multipart, resumable, or streaming object upload support.
- URL-token authentication for constrained clients.
