In T309260, we turned on sampling in the MobileWebUIActions and DesktopWebUI schemas at the 9 wikis we're partnering with in the mobile talk page improvement work.[i]

This task involves doing the above for the yet-to-be-determined wikis we'll be partnering with for the deployment of the Usability Improvements on desktop and mobile. [ii]

Requirements

• Sampling is turned on in the MobileWebUIActions and DesktopWebUI schemas at the yet-to-be-determined wikis the Editing Team is partnering with on the desktop/mobile Usability improvements.
• EditingAttemptStep schema's sampling rate is adjusted such that it matches the MobileWebUIActions and DesktopWebUI schemas' current sampling rates:

'wgWMEDesktopWebUIActionsTracking' => [
        'default' => 0,
        'desktop-improvements' => 0.2, // T258058
        'officewiki' => 0,
        'testwiki' => 1, // T256992
],

'wgWMEMobileWebUIActionsTracking' => [
        'default' => 0.1, // T220016
        'enwiki' => 0.01, // T295432
],

Done

• ===Requirements are implemented
• Once all patches to resolve this task are merged, @MNeisler to verify sampling rates are synchronized and instrumentation is working as expected
• Notify @jwang when the patch(es) to resolve this ticket land so that she can update relevant documentation

i. ja.wiki, ar.wiki, fr.wiki, ko,wiki, vi.wiki, he.wiki, bn.wiki, zh.wiki, and ht.wiki. via T294609.
ii. The work to finalize this list of partner wikis is happening in T296357.
