# Context This PR introduces the ability to permanently delete revisions from a post while maintaining the changes implemented by the revisions. Additional Context: /t/90301 # Functionality In the case a staff member wants to _remove the visual cue_ that a post has been edited eg. <img width="86" alt="Screenshot 2023-01-18 at 2 59 12 PM" src="https://user-images.githubusercontent.com/50783505/213293333-9c881229-ab18-4591-b39b-e3419a67907d.png"> while maintaining the changes made in the edits, they can enable the (hidden) site setting of `can_permanently_delete`. When this is enabled, after _hiding_ the revisions <img width="149" alt="Screenshot 2023-01-19 at 1 53 35 PM" src="https://user-images.githubusercontent.com/50783505/213546080-2a9e9c55-b3ef-428e-a93d-1b6ba287dfae.png"> there will be an additional button in the history modal to <kbd>Delete revisions</kbd> on a post. <img width="997" alt="Screenshot 2023-01-19 at 1 49 51 PM" src="https://user-images.githubusercontent.com/50783505/213546333-49042558-50ab-4724-9da7-08bacc68d38d.png"> Since this action is permanent, we display a confirmation dialog prior to triggering the destroy call <img width="722" alt="Screenshot 2023-01-19 at 1 55 59 PM" src="https://user-images.githubusercontent.com/50783505/213546487-96ea6e89-ac49-4892-b4b0-28996e3c867f.png"> Once confirmed the history modal will close and the post will `rebake` to display an _unedited_ post. <img width="868" alt="Screenshot 2023-01-19 at 1 56 35 PM" src="https://user-images.githubusercontent.com/50783505/213546608-d6436717-8484-4132-a1a8-b7a348d92728.png"> see that there is not a visual que for _revision have been made on this post_ for a post that **HAS** been edited. In addition to this, a user history log for `purge_post_revisions` will be added for each action completed. # Limits - Admins are rate limited to 20 posts per minute
