Statement
A rendezvous architecture must remove velocity relative to the destination. Carried propellant, external beams, stellar-photon assists, interaction with the interstellar medium, and predeployed infrastructure are separate proposed approaches; a flyby does not satisfy this requirement.

Assessment rationale
Relative arrival velocity must be removed for rendezvous. Published carried-propellant, photogravitational, magnetic, and electric concepts are distinct conditional approaches rather than one demonstrated braking capability.

Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
A representative braking demonstration with measured mass, thermal behavior, navigation error, environmental uncertainty, failure recovery, and reserve would raise readiness.
