What this is

Members carried onto the Meridian claims platform during the vendor cutover and still receiving capitation, with no active eligibility span behind them in CBES.

Why single-system review misses this

CBES correctly shows these cases closed; Meridian correctly shows enrolled, paying members. Each system passes its own audit — only a cross-system join on the cutover window exposes payment with no eligibility.

One member, two systems

Member CAS-00000026 — the eligibility record and the payment record, on one clock. The hatched window is the seam.
