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

Membership history

Growth

4 measurements spanning 50 days, net +2. 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 275–278 and does not start at zero.
