F11-ND: Yes
Rationale
With cache admission and serving enabled, NFD stores returned Data and can satisfy a later Interest while the producer is disconnected. The object must still be cached and acceptable under freshness/trust rules. This is best-effort deferred retrieval, not custody, disk durability or guaranteed delivery.
Assessment method
Primary specifications and pinned-code analysis; no execution
Source context
NFD 24.07 forwarding pipeline
Outstanding qualification
Prime an enabled CS with signed Data, disconnect its producer, and fetch the same accepted Data later. Test eviction, freshness expiry and restart separately; no disk durability claim.
