Clicks to items in the main menu are logged via the MobileWebMainMenuClickTracking schema for 50% of all users. For AMC users we want to log all clicks and we need a way to distinguish these users from normal users.
= Acceptance criteria
[] Update the schema to have an AMC flag
[] Update the schema number in MobileFrontend and move to Minerva codebase
[] Sampling rate should be 100% if the user is AMC, otherwise use the configurable sampling rate
[] Log whether the user is in AMC mode using the new schema revision ID
= Open questions
Do we want to use the existing "mode" field in https://meta.wikimedia.org/wiki/Schema:MobileWebMainMenuClickTracking to track "amc" e.g. "amc+stable", "amc+beta" or create a dedicated field with boolean?
= Sign off steps
[] Document the oversampling behaviour for AMC on the schema's talk page so Tilman can understand it
