Empty ranks from FULL OUTER JOIN return empty strings, not '0'. Fixed int() parsing to handle empty fields. Now regime clustering is verified: - Φ queries retrieve phase transition papers - Ω queries retrieve critical/eigensolid papers Build: 2987 jobs, 0 errors (lake build)
- Mirrors HachimojiCodec.lean classifyEquation exactly (Ω,Λ,Ζ,Φ,Π,Σ,Ρ,Κ) - STATE_QUERIES maps each state to semantic search terms (mirrors §4) - Hybrid search via arxiv-pg podman container (pg_trgm + pgvector HNSW) - Demo batch demonstrates state diversity: E=mc² (Φ), 0=1 (Ω), ∫ (Π) Build: lake build pending verification
