- Include client endpoint in cache key (different endpoints = different results) - Return string hash (SHA256) instead of int for better ComfyUI compatibility - Update test to expect string hash with 64 character length This should provide more reliable caching behavior in ComfyUI when using deterministic generation with seeds.
