=== Deployment timing !!**@ppelberg to define**!! === Announcement(s) //See T420667.// === Bucketing criteria **Bucketing Requirements:** * Bucketing should include both registered and unregistered users at participating wikipedias identified in T420664. This will require the use of the [edge-unique ](https://wikitech.wikimedia.org/wiki/Test_Kitchen/Conduct_an_experiment#Experiment_design:_identifier_type) identifier type. Note: This means enrollment will be per-device. * All users, who are editing a **mobile web or desktop** main namespace page (NS:0) using the visual editor, at any of the Wikipedias should have a 50% chance of being included/bucketed into the A/B test's control or treatment group. * The treatment group should have Edit Suggestions enabled while the control group will not. * Each device should remain in the same test group for the duration of the test (and across sessions and pages). Note: If the cookie is cleared manually or automatically – by, for example, a privacy enhanced browser – the client is issued a new wmf-uniq cookie, and they may or may not end up enrolled or even assigned to the same group. === Instrumentation Requirements * Ensure Test Kitchen stream is configured appropriately * . * . === Participating wikis NOTE: List of wikis was finalized via T420664. | ID | Wiki | |----|------| === Open question(s) - [ ] 1.
