+IPC Interface
+-------------
+
+- `BlockTemplate.submitSolution` now returns `reason` and `debug` rejection
+  details in addition to the boolean result. Clients must regenerate IPC
+  bindings from the updated `mining.capnp` schema to use the new method. The
+  previous `@7` method now returns an error directing clients to update. (#34672)
+
+- `BlockTemplate.submitSolution` now reports duplicate blocks as failures with
+  `reason="duplicate"`, matching `Mining.submitBlock`, instead of returning
+  success for duplicate submissions. (#34672)
