+## Implementation report
+
+Cleanup report:
+
+- Registry Coder/Reviewer child Workers were no longer present in the spawned-child registry at cleanup time, so no StopPod action was available for them.
+- Child implementation worktree removed:
+  - `/home/hare/Projects/yoi/.worktree/00001KVZKSV6C-backend-runtime-registry`
+- Child implementation branch removed:
+  - `work/00001KVZKSV6C-backend-runtime-registry`
+
+Operational note:
+- User noted StopPod should be run one-by-one rather than through parallel multi-tool execution; future cleanup will follow that.
