+The `FlashHead` prefix is only a safety trip — it makes stock vLLM refuse the model when the plugin is missing. When the plugin is installed it simply **strips the prefix** and lets vLLM load the standard base architecture (`FlashHead<Base>` → `<Base>`), so **any architecture vLLM already supports works**.
+
+FlashHead itself activates from `flash_head_cache_dir` in the model config, independent of the architecture name. As a result a model that keeps its **standard** architecture name (no `FlashHead` prefix) but ships a `flash_head_cache_dir` also gets FlashHead applied — the prefix is purely about the no-plugin safety error.
