 ### D&D NPC Normalization Prompt Ordering And Cache Boundaries
 
 NPC normalization has a distinct prompt and response-schema identity from NPC
-extraction. Its stable message tiers are the common D&D system and identity
-assets, followed by package-owned task and normalization instructions. Cache
-boundaries follow the shared identity tier and the package instructions. The
-variable tail contains the private candidate-name-and-range input and a
-windowed transcript input whose cited units provide local context; neither has
-a cache boundary because it changes with the document.

-This prompt intentionally omits extraction-evidence and campaign-reference
