# Producer Upload Implementation Roadmap

The producer upload implementation described by this roadmap is complete.
Current behavior is documented outside roadmap files:

- [README](../../README.md)
- [Source bundle contract](../integrations/source-bundle.md)
- [HTTP upload contract](../integrations/http-upload.md)
- [Operations](../operations.md)
- [Troubleshooting](../troubleshooting.md)
- [Application internals](../internal/app.md)
- [Development policy](../policy/development.md)

This file now tracks only producer-upload work that remains outside the current
implementation.

## Deferred Work

- Durable idempotency storage across server restarts.
- Database-backed queues or durable producer retry processing.
- `UploadAndWait`, long polling, run cancellation, run retry, or run listing
  helpers.
- Zstandard archives.
- Multipart, resumable, or streaming upload protocols.
- URL-token authentication.
- Browser UI or public exposure defaults.
