Growth

2956 measurements spanning 11 days, net +5,577. 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 1,126,130–1,133,381 and does not start at zero.
