G04-I2: Yes
Rationale
NetDb stores records on key-selected floodfill subsets, and additional routers can join that role. This supplies a mechanism to distribute discovery work instead of one compulsory fixed coordinator. Uneven keys, replication and routing costs remain.
Assessment method
Documentary analysis
Source context
Primary specification / explicit profile inference
Outstanding qualification
Measure floodfill storage/query distribution, replication, opt-in behavior, churn and adversarial key concentration. Architectural credit does not establish linear scaling or G05.
