F27-SC: No
Rationale
The selected SCION/application-UDP composition provides path discovery, selection and datagram forwarding, without a receiver-window negotiation protocol. Path-segment validity and expiration govern usable routing state, not an agreement about endpoint wake or receive times.
Assessment method
Primary documentary assessment; no new runtime test
Source context
Primary protocol documentation; selected-composition assessment
Outstanding qualification
This is scoped to the declared UDP stack, with no scheduling application or negotiated link-power profile added. Path control and failure recovery remain available but do not alone satisfy F27. No claim is made about every possible transport or carrier used with SCION.
