ICPI Live Cutover Window
Window Goal
Execute the first real env-only ICPI gateway cutover in the current runnable environment by switching only the API gateway target from old colocated ICPI hosting to the extracted svc-icpi runtime.
Constraints held during the window:
- gateway route shape unchanged
- auth behavior unchanged
- old colocated ICPI hosting kept available
- rollback kept as an env flip plus gateway restart
