@SWakiyama and @CBogen I modified this task to make it clearer from a development perspective. I think the details are the same, but if you disagree please let me know. One thing I wasn't sure about from what we had - how many notifications do we want to send per user per week?

Some notes before working on implementation:

• Ingest a list of article image pairs
  • Filter out values below confidence score.
  • Generate list of unique articles titles maybe?
• Find and note watchers for each article. ( useful code for reference )
  • Generate unique users maybe?
  • Whilst doing this, perhaps fetch edit count and filter all users with less than 500 edits
• Find the last time each user edited each watchlist time.
• Load previous image suggestion notifications for each user and see if they were previously notified about this article?

• As notification is triggered for each user add a notification count and if = 2 move skip onto the next set up.

• Define notification

EchoEvent::create( [
	'type' => 'my-ext-topic-word',
	'title' => $title,
	'extra' => [
		'revid' => $revision->getId(),
		'source' => $source,
		'excerpt' => EchoDiscussionParser::getEditExcerpt( $revision, $this->getLanguage() ),
	],
	'agent' => $user,
] );

Resubmitted to "master" branch here: https://gerrit.wikimedia.org/r/c/mediawiki/extensions/ImageSuggestions/+/778216

https://gerrit.wikimedia.org/r/777350

Note that as per T283865, we'll only be notifying users of suggestions with a confidence score of >=80%. I've updated the acceptance criteria to reflect that.

Moving to blocked until the code has been deployed, at which point I'll do a few more tests.

Here's the command to run for each wiki, with the params set to above acceptance criteria (and T295369)
