SI-5 is a canonical quantum gravity programme built on nine physical axioms. Space is modelled as a void cubic lattice at the Planck scale; time emerges from a Page-Wootters clock field; gravity is a dynamical symmetric tensor field on the lattice nodes. The framework derives the Einstein field equations, Schwarzschild and Kerr solutions, gravitational waves, FRW cosmology, and the ADM Hamiltonian from the nine axioms. The quantum theory is constructed via canonical quantisation with a BRST ghost sector; the constraint algebra closes at two loops with corrections bounded by 1263 × (lP/L) ². The Normal-Ordering Theorem removes all perturbative vacuum energy contributions while preserving the Casimir effect, providing a perturbative mechanism for the cosmological constant problem. The Standard Model colour gauge group SU (3) is uniquely derived from the cochain algebra of the three-dimensional cubic lattice (Theorem 51. 1). The Higgs mechanism and all gauge boson masses are recovered on the lattice. Six parameter-free predictions are made, including a dark energy equation of state w = −1. 000 (testable by DESI), a Lorentz violation coefficient ξ₂ = −1/8, and a Higgs self-coupling upper bound λ < 1. 004. This document is SI-5 version 6, comprising 55 sections and approximately 5, 900 paragraphs. A companion short paper with the key results and verifiable calculations is in preparation.
