JSON-LD ⊂ SPXI ⊄ Schema: The Operational Depth of the Semantic Packet Protocol

EA-SPXI-15. JSON-LD is a proper subset of SPXI. SPXI is not a subset of Schema. This document specifies the operational depth that distinguishes SPXI from schema markup: a five-layer stack of measurement, compression architecture, protection, dispersal, and durability testing. Five layers: (I) Measurement: γ scoring, Drowning Test, Density Score (Δ), Semantic Decay Delta (SDD), Provenance Erasure Rate (PER). (II) Compression: entity-definition packets, disambiguation matrix, three-tier compression (full/canonical/kernel), holographic kernels, citation-density engineering. (III) Protection: Semantic Integrity Markers (SIMs), integrity locks, Sovereign Provenance Protocol, supraliminal inscription. (IV)…
