What type of failure points toward a necessary design change in cryogenic sealing mechanisms for operational vehicles?

Answer

Propellant leak causing a post-splashdown fire.

A propellant leak causing a post-splashdown fire points to a specific failure in the shutdown and securing phase, suggesting the tanks and propellant management system need better sealing mechanisms.
