EE: SISYF Compilation Evidence

Experimental evidence collected during SISYF compilation runs. These findings inform future updates to the extraction matrix and 5D architecture. The improved versions live here as compiler input data; the raw originals from the integration-tests session are preserved in Phase 2I Integration Tests — Design Questions Requiring Real Data (same b/41 folder).

Collected by: Phase 2I-4 (first compilation run, 2026m03d25) and subsequent sessions.

• D1/D2 Testing Matrix — Cross-Model Usage Evidence
• D2 Chaining Evidence — Natural Multi-Type Combinations
• Alignment Class Echoes — Cross-Model Topic Matches
• PoR Field Collision Check — “model” Ambiguity
• PoR Field Usage Census — Phase 2I-4 First Compilation
