KEFE P: Possibility and Physical Realization - Typed candidates, accessibility, ordered history, and source ownership

KEFE P defines the typed bridge between possible structural continuations and physically realized events within the KEFE Foundation suite. It separates candidate generation, relational admissibility, physical fit, selection, and source-owned realization while establishing representation-independent accessibility and predictive equivalence. The paper also distinguishes transported packets and prepared links from their realized and healed states.
