Context

More experienced contributors are interested in specific articles that they watch and edit. Section-level image suggestions notifications (SLIS notifications) is an extension of article-level image suggestions (Epic T292142) to recommend images for the section of articles contributors are watching or recently edited. and is built upon Section level image suggestions data pipeline work described in T311814.

The goal is to embed the recommendation in their existing Wikipedia activities, thus increasing the likelihood they will review the recommendations and add selected images as part of their current editing workflow. Based on the information provided in the notification, the user can go through their normal image addition workflow. Contributors can choose to edit via Wikitext or Visual Editor after receiving the image suggestions notification and can review the image + section/article information in the notification. We will not provide any help with adding the image itself; just the opportunity for the user to review the match.

Use Cases
As an Experienced Contributor, I want to receive a notification if there is an image suggestion for a section of an article that I have edited or watched so that I can use it to illustrate those sections/articles.
