+## P1: Reduce JoinIR wrappers (Pattern6/7) ✅
+
+- Scope:
+  - Drop JoinIR-side Pattern6/7 wrapper modules (plan/composer is SSOT).
+  - Keep routing through single_planner → composer adopt.
+- Guardrails:
+  - No change to pattern selection or logs.

 ## Next (planned)
 
-- P1: Pattern6/7 JoinIR wrapper → composer entry only
 - P2: Router pattern-name branching reduction (planner outcome + composer SSOT)
 - P3: Facts/Feature expansion if needed
