-Expression Compiler v4 — All known issues fixed:
-1. Strips quotes from field names ('field' -> field)
-2. Validates all field IDs exist in registry
-3. Uses novel GROUP keys (pv13_rcsed_6l etc) instead of always sector
-4. Explicit arity in LLM prompt
-5. Post-compile sanitization
+Expression Compiler v5 — Fixed per-component sign logic,
+correct weight semantics (weights inside rank don't linearly combine),
+removed double-negation bugs.
