Section 3.4.3. says:
received Sequence Number against the receive window. In constructing the full sequence number, if the low-order 32 bits carried in the packet are lower in value than the low-order 32 bits of the receiver's sequence number counter, the receiver assumes that the high-order 32 bits have been incremented, moving to a new sequence number subspace. (This algorithm accommodates gaps in reception for
It should say:
received Sequence Number against the receive window. In constructing the full sequence number, if the low-order 32 bits carried in the packet are lower in value than the low-order 32 bits of the receiver's left edge's sequence number counter, the receiver assumes that the high-order 32 bits have been incremented, moving to a new sequence number subspace. (This algorithm accommodates gaps in reception for

--VERIFIER NOTES--
There is no mention of a "left edge sequence number counter" in 4302.
