Flow patterns (42-month cumulative)

Inbound (numbers acquired)

Direct transfer from another RespOrg	68,172.0
Harvested from disconnect pool	32,694.0
First assigned from spare pool	15,405.0

Standard disconnect aging process (3+ months in DISC)	1

Of the 5,505 disconnect episodes this RespOrg has sent through aging, 100% were abbreviated (1–2 snapshots in DISC status). That's a strong early-disconnector signal, this RespOrg routinely releases numbers before the full 3–4 month aging window. Worth checking daily for vanity drops.
