Story 1: Admin can prevent a user or IP from editing one or more specific pages

• On Special:Block, add a section under the username/IP input box for Type
• The options should be two radio buttons with labels and help description text.
• The top radio button, which should be selected by default' should read Site-wide block. When a block is saved with this selected, the block should behave exactly as it does today.
• The second radio button should read Partial block. When selected, a TagMultiselectWidget OOUI element should allow for admins to type up to 10 pages from which the user should be blocked from editing.
  • Page blocks can only be set for existing pages.
    • Validation should occur in the input field or via error message when the "block this user" button is pushed — whichever is simpler
  • Pages can be from any namespace, the user must type in the namespace and colon (e.g. Template:Foobar)
  • If a page is moved, the user should still be blocked from editing (e.g. block by page ID, not page name)
    • Only one block per user (like it is today) — to update the block, admins will need to modify the block.

Story 2: The block is logged and visible on wiki

• Block logs
  • Should display everywhere the current block displays: user page, Special:Contributions, Special:Block, and Special:Log
  • Log should include TIMESTAMP Admin-who-blocked (t|c|b) blocked BadApples (t|c) from editing the page(s) Foobar with an expiration time of N (reason) (unblock | change block)

Story 3: When the user attempts to edit the page, they should be notified.

• When a user attempts to edit an applicable page, they should see a new type of block warning message which include information on their block
  • reason
  • expiration
  • blocking admin
  • Modeled off of MediaWiki:Blockedtext, information that they are only blocked from that page, but can edit the rest of the wiki. (copy tbd)
• Should appear:
  • For all supported editors on desktop web
  • For all supported editors on mobile web
  • API edits should also return an appropriate error message
