LFIS–17: Canonical Concept Registry for Representability Closure

LFIS–17 registers the canonical concepts required for the representability-closure arc of Light Frame Cadence Geometry. The volume records five minimal concept entries—cadence continuity beyond radial representation, routing activation threshold, frame genesis, terminal representability bounds, and global cadence closure—into the LFIS concept registry. These entries describe the transition structure developed across LFIS–13 through LFIS–16: multi-ray closure, routed remainder, completion, representational rest, and renewed local representability. The concepts are stated in sterile infrastructure form for citation and registry use, without adding dynamics, cosmological narrative, or phenomenological argument. LFIS–17 supplies the canonical concept labels used by later LFIS volumes when referring to representability closure, routing activation, frame re-entry, terminal bounds, and global cadence-continuity commitments.
