Written by the group; not a statement by this register.

Membership history

Growth

6 measurements spanning 45 days, net +4. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 212–219 and does not start at zero.
