sewn up
Locked down completely
Sewn up means securely settled or guaranteed.
A deal that's all sewn up is finalized beyond doubt.
An election sewn up before votes are counted has an inevitable winner.
The image is of stitching something closed so nothing can escape or change—complete, finished, locked in.
