 ## Accumulated Context
 
@@ -300,6 +301,8 @@ Recent decisions affecting current work:
 - [Phase 09]: Genre and style admin option values are decimal strings because pact.Option.Value is a string
 - [Phase 09]: Artists uses only the shared cabana list and CRUD engines; the controller contains identity, asset paths, model factory, and permission declaration only
 - [Phase 09]: Artist name_key and slug remain model-owned lifecycle fields and are not exposed by the admin writable projection
+- [Phase 09]: The Phase 9 Genre tracer remains the one production controller; form capability was added without a parallel route or identity
+- [Phase 09]: The tracer list and columns were already byte-equivalent to the tracked Winter source, so Task 2 added behavioral proof rather than rewriting them
