FSPS Reader Primer Foundational Axioms and Definition Hygiene — Repositioning the Speed of Light

This volume serves as a reader primer for the FSPS (Foundational Structure / Projected Structure) framework. It combines the axiomatic core of FSPS–00 v2.2 with a focused definition-hygiene note on the speed of light. The purpose is not to introduce new physical laws, but to stabilize interpretation by clearly separating foundational (FS) concepts from projected (PS) quantities. FSPS–00 v2.2 presents a minimal axiomatic system in which physical reality is described as a projection from a non-geometric informational substrate (FS) through a stabilizing boundary structure (Ω) into the observable geometric world (PS). Time is treated as an emergent stability parameter, gravity as stability geometry, observers as dynamic fixed points, and physical laws as projection invariants. The accompanying note, Repositioning the Speed of Light, addresses a persistent source of conceptual confusion: the identification of the speed of light with the velocity of photons. Within FSPS, the speed of light is clarified as a constraint on causal propagation in PS rather than an intrinsic particle property. This clarification prevents layer-mixing errors, resolves common pseudo-problems, and prepares a consistent treatment of causality, observation, and black-hole regions. This collected volume is intended as an entry point and reference document for readers engaging with FSPS-based work, providing both the constitutional axioms and an example of internal definition hygiene essential for maintaining interpretive coherence.
