What is an active student for the Martialnote plan?

A student is active if, today, either of these is true:

• they had at least one activity in the last 90 days: an attendance at a class (Present or Late; Excused does not count, a cancelled session does not either), a recorded dues payment, or a curriculum item marked Learned or Validated. Each activity counts on its own date;
• their record is recent (less than 90 days old): for a record created in the app, that is the day it was created, which nobody can change; for an imported record, it is the spreadsheet enrollment date. A record imported without a date never counts as recent.

What does not count: the Active / Inactive status on the profile, and the displayed enrollment date (Enrolled since), which can be changed freely for display. The Martialnote plan screen (owner only) shows today's number, the current month's measurement and the list of these students with each one's reason.
