Scope Notes

• The current recommended customer-facing contract for Wan text-to-video is /v1/video/generations, not the Ali Bailian-compatible submit path.
• The Ali Bailian-compatible path is primarily for image-to-video, first-last-frame, subject-reference, and other Ali-shaped migration workflows.
• Crazyrouter can internally route to official, ApiPass, Kie, or other third-party providers, but those providers do not define customer protocols.
• Beta rows can still be shown publicly now; after launch, use production task logs to close live evidence and then remove the Beta label.
