F37-SC: Yes
Rationale
The selected IPv4 underlay carrying SCION UDP uses optional router-local AQM. The affected egress queue observes its own pressure and applies congestion-dependent dropping at that location.
Assessment method
Primary specifications and explicit IP policy composition
Source context
IETF AQM and DiffServ; I2P and SCION transport documentation
Outstanding qualification
The witness belongs to the explicitly selected IP composition. No endpoint identification of every congested hop, encrypted-payload inspection, ECN support or overlay-wide congestion guarantee is required. Local queue action does not recover upstream capacity or force an unresponsive sender to reduce its rate.
