 ## Recommended Next Passes
 
-1. Continue splitting remaining `__init__.py` node classes by family after
-   behavior is covered by smoke checks.
-2. Continue splitting the internals of `hardcore_role_graphs.py` by action
-   family once generated edge cases are covered by smoke fixtures.
-3. Add more route-level smoke fixtures for generated edge cases that are not
-   covered by the current static Krea/SDXL/caption metadata fixtures.
+1. Keep new node classes in their owning `node_*.py` or `loop_nodes.py`
+   module, with registration/display docs covered by the audit.
+2. Keep `hardcore_role_graphs.py` as the dispatch surface; add behavior in the
+   existing `hardcore_role_*` action-family modules only when a concrete
+   generated edge case needs it.
+3. Add route-level smoke fixtures only for observed generated edge cases or new
+   metadata fields that affect Krea2, SDXL, or caption output.
