This appendix presents a unified Extended Classical Mechanics (ECM) resolution of the minimal length postulate in quantum gravity. By replacing spacetime ontology with a pre-dimensional frequency–phase field framework, ECM demonstrates that the Planck scale is not a fundamental spatial limit but a projection threshold of dimensional emergence. Across 15 ECM foundational papers, physical quantities such as mass, energy, and gravity are reformulated as projection operators acting on a non-dimensional field. Encoding saturation replaces ultraviolet divergence, and pre-Planckian regimes are defined as non-dimensional but mathematically structured domains of existence.

Standard quantum gravity assumes spacetime as fundamental. ECM replaces this with:
𝔽(f,θ) → 𝔇[space, time, gravity]
Spacetime is a derived projection of a non-dimensional frequency–phase field.
−ΔPE_ecm ≡ 𝔽_pre-dim(f,θ)
For θ ≪ θₚ:
Mass:
ΔMᴍ = 𝔇_M[𝔽(f,θ)]
Kinetics:
KE_ecm = 𝔇_K[∂θ𝔽(f,θ)]
Energy:
E(f) ≡ 𝔽(f)
ℓₚ ≡ θₚ (projection threshold)
Not a minimal spatial length but the first dimensional emergence event.
𝔈_univ(θ) = 𝔇[𝔽(f,θ)] / 𝔽(f,θ)d𝔈_univ/dθ → 0 as θ → θₚ
This defines finite projection capacity of frequency-to-dimension mapping.
Quantum gravity assumes divergence at ℓ → 0. ECM replaces this with:
θ < θₚ → no spacetime domain exists
Thus, divergence is a representational artifact, not physical reality.
𝔽(f,θ) → −ΔPE_ecm → ΔMᴍ → KE_ecm → 𝔇(space, time, gravity)
𝕌_pre-dim = 𝔽(f,θ), θ ≪ θₚ
A non-dimensional frequency ontology without spacetime embedding.
θ = θₚ → 𝔇[𝔽] ≠ 0
Planck epoch represents first successful dimensional projection.
𝕌 = 𝔇[𝔽(f,θ)]
Birth → Evolution → Fate as projection lifecycle of frequency field.
ℓₚ ≡ maximum stable dimensional encoding threshold
Not a minimum length, but first stable emergence of spacetime encoding.
The ECM framework demonstrates that the minimal length postulate in quantum gravity arises from extending spacetime-based reasoning beyond its valid domain. In ECM, reality is fundamentally a non-dimensional frequency–phase field (𝔽(f,θ)), and spacetime, mass, energy, and gravity are emergent projection structures. The Planck scale is therefore not a smallest physical length but a dimensionalization threshold marking the onset of observable spacetime structure.
