This page provides foundational methodological guidance for the Extended Classical Mechanics (ECM) framework. It establishes canonical structural sign conventions governing Dark Energy, manifestation-layer transformations, and invariant conservation identities, ensuring consistent theoretical interpretation and cross-paper alignment. Negative Apparent Mass is defined as the structural potential energy deficit: Mᵃᵖᵖ ≡ −ΔPEᴇᴄᴍ This definition separates structural and manifestation layers while maintaining the invariant relation: Mᵃᵖᵖ + ΔMᴍ = 0 The document serves as a reference for ECM methodological specification, appendices, and future research alignment.
