L01-RT: Yes
Rationale
Reticulum 1.5.5 explicitly distinguishes protocol rights from the reference implementation license. The versioned manual identifies the reference implementation and manual as authoritative, and states that the protocol was dedicated to the public domain in 2016. Its Public Domain Protocol section expressly permits independent implementation, improvement and adaptation, including uses excluded by the reference-code license when implemented from scratch. This meets the use/implementation criterion for the selected native serial/Link profile without treating the Python distribution as unrestricted.
Assessment method
Documentary rights-scope review; no runtime or legal clearance
Source context
Version-pinned primary repositories and official manuals, 2026-10-15
Outstanding qualification
This credits the author-declared permission to implement the protocol, not unrestricted copying of protected code or manual prose. The reference license covers associated documentation and includes use restrictions and notice requirements; those are not erased by the protocol dedication. Compatibility is a separate claim. E03 remains Pending for an OSI-licensed complete implementation; L02 patent commitments remain separately unestablished.
