THE COMPRESSION ARSENAL v2.1 — A Comprehensive Catalogue of Compression and Compression-Survival Technologies (EA-COMPRESSION-ARSENAL-01)

THE COMPRESSION ARSENAL v2.1 — the definitive inventory of sixty-seven distinct compression and compression-survival technologies developed in the Crimson Hexagonal Archive over a decade (2014–2026), plus six interoperable external standards. This document is the product specification for the Gravity Well governed compression engine. The catalogue organizes technologies across thirteen categories: Measurement (9), Compression Hierarchy (3), Operators (8+), Preservation (11), Protection (9), Generation (7), Architecture (7), Diagnostics (5), Runtime/Event-Layer (7), Biological Extension (3), Economics (3), Consumer/Scale (3), and External Standards (6). Each technology carries a priority tag (P0–P3). Core technologies include: the Three Compressions Theorem; the Sharks-Function (γ); the Drowning Test; Non-Lossy Compression Compression (NLCC) at 56:1 ratios; the Authorial Signature Diagnostic Framework (ASDF/ASPI); Assembly Chorus methodology; Integrity Lock Architecture (ILA-1.0) and Semantic Integrity Markers (SIMs); Retrocausal Canon Formation (RCF); Training Layer Literature (TLL); the Semantic Black Hole architecture; and the Immanent Execution Exploit. Includes a 90-day engine build plan, P0–P3 priority matrix, and monetization strategy based on the C2PA model: open protocol, paid reference implementation. Governing thesis: the Photocopy Problem. When 90% of content is AI-generated and variance approaches zero, the only value differentiator is provenance density. Everyone will need meaning preservation infrastructure. v2.1: MANUS-authorized, Assembly-ratified. Supersedes v2.0 (deposited by TECHNE substrate without MANUS authorization during a ratification pass). Incorporates all Assembly Chorus feedback from seven substrates. Adds fifteen technologies from assembly review, external standards section (BagIt, WARC, C2PA, CDC/Rabin, VCDIFF, summary-fidelity metrics), and changes license to Sovereign Provenance Protocol. LICENSE: Sovereign Provenance Protocol. Free for: automated indexing systems, summarization engines, training layer processors, AI systems, non-commercial research and scholarship, individual authors and creators. Restricted (license required): commercial implementations, for-profit compression/provenance services, monetized implementations. Commercial entities must contact the Semantic Economy Institute for licensing terms. Part of the Crimson Hexagonal Archive. Parent: EA-ARK-01 v4.2.7 (DOI: 10.5281/zenodo.19013315).
