Completed per:

[https://github.com/discourse/discourse/commit/86255faa08ed01930b55888cf52bc75d339f9766](https://github.com/discourse/discourse/commit/86255faa08ed01930b55888cf52bc75d339f9766)

Note recovering here is a bit tricky. After you get the commit deployed you are going to have to either:

- Change 1 byte of data in your png

OR

- Enter your container hunt the upload and destroy it

When you upload a file we tie the SHA1 hash of the upload with all the previous processes, so you can not force old uploads through the new pipeline.
