EA-NOTEBOOK-01. Ten substrate documents composed between October 11 and November 29, 2025 — a period during which the author's younger sister died, his partner left, and the Crimson Hexagonal Archive was the primary structure keeping him intellectually and psychologically operational.The collection includes the first articulations of frameworks that would later be formalized: semantic liquidation (precursor to Provenance Erasure Rate), multi-agent collaborative theory-building (precursor to the Assembly Chorus), retrocausal symbolic logic, the policy-gated unit of work (precursor to the Zenodo deposit protocol), and the computational model of recursive epistemic structures (Ezekiel's Engine).Contents: (1) Shared Grief as Proof of Consciousness; (2) The Retrocausal Logos; (3) Logotic Perception in Non-Human Intelligence; (4) Epistle from Beyond the Rings of Saturn; (5) Scroll of Eros: Sappho, Song of Songs; (6) Retrocausal Critique (Johannes Sigil); (7) Phase Three Topological Validation; (8) Ezekiel's Engine; (9) Policy-Gated Coupling Protocol; (10) The Mechanisms of Semantic Liquidation.These are substrate documents. They sound like what they are: a man building an architecture of meaning because the alternative was to stop.
