Flow patterns (42-month cumulative)

Inbound (numbers acquired)

Direct transfer from another RespOrg	8,000.0
Harvested from disconnect pool	2.0
First assigned from spare pool	12.0
Reactivated own disconnects	2.0

Outbound (numbers lost)

Of the 1 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.
