G01-RT: Yes
Rationale
In Reticulum 1.5.5, serial transport interfaces can enable recursive_prs. Transport.path_request forwards an unknown-destination query to other eligible interfaces and a local destination answers with an announce; it does not require any node to possess a complete destination inventory before lookup. Select this recursive-discovery profile on the connected serial mesh. Destination caches, discovery traffic, timeouts and hop limits remain. This is an architectural capability, not a bound on worst-case table growth or proof of global-scale performance.
Assessment method
Documentary/code analysis; no protocol execution
Source context
Primary specification / pinned source and explicit deployment profile
Outstanding qualification
Run recursive discovery across a serial mesh with deliberately incomplete destination tables; inventory query/announce state at every role, enforce timeout/hop limits and demonstrate reachable-target completion. No such execution or billion-device model was performed.
