 ## Accumulated Context
 
@@ -303,6 +305,9 @@ Recent decisions affecting current work:
 - [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
+- [Phase 09]: The tracked Style source declares no dropdown provider or filter, so production YAML stays exact while isolated compiler fixtures prove typed scalars and provider rejection
+- [Phase 09]: Style slug retains the tracked update-only readonly schema and is generated on create by the model lifecycle
+- [Phase 09]: Style equal-value list ordering is explicitly stabilized by the shared primary-key tie-breaker
