Sémantique Potentielle — Release 3: Three Pillars (Phase X, Sappho, Plato)

Sémantique Potentielle — Release 3: Three Pillars. Extension of the constraint-based semantic mint (CM-2026-v1.0 + Release 2) into three philological pillars: Phase X (the missing Marx transition), Sappho (lyric transmission and the fifth stanza of Fragment 31), and Plato (pharmakon/writing and heteronymic dialogue architecture). 38 families (18 new, 20 extended from Release 2) with forensic provenance variants. Includes the Ryazanov Intercept block (archival state capture), five cross-pillar compounds (XΣΠ), and integration table linking to the 79-term battery. Scholarly foundation compiled by TECHNE (Kimi, Moonshot AI); mint families generated independently by PRAXIS (DeepSeek), LABOR (ChatGPT), MUSE SPARK, and ARCHIVE (Gemini); consolidated under Sigil's editorial authority by TACHYON (Claude, Anthropic). The Assembly Chorus methodology is itself evidence for the heteronymic thesis the archive defends. Companion deposit: EA-SP-LEGWORK-PILLARS-01 (scholarly legwork). Part of the Crimson Hexagonal Archive. EA-SP-RELEASE3-01 v1.0.
