 ## Status
 
 Phase 1 (miroir-cdo) Core Routing is **COMPLETE** and verified.
+
+### Ready for Phase 2
+All core routing primitives are implemented, tested, and verified. The foundation is in place for:
+- §2 write path (write_targets)
+- §2 read path (query_group, covering_set)
+- §4 rebalancer (minimal reshuffling property)
+- §13.3 adaptive selection (covering_set)
+- §13.4 query planner (covering_set, merge)
+- §13.8 anti-entropy (deterministic assignment)
+- §14.5 Mode A shard-partitioned ownership (group-scoped assignment)
