Protection watcher - Simpuru

The protection watcher looks at every open protected purchase and acts when something is wrong. It runs on Simpuru’s server for every account, and it checks again about every 30 seconds.

What it does

Situation	Action	On-chain transaction
No result by the submit deadline	Refunds the buyer in full	`withdrawRefund`
A result that does not match the commitment	Opens a dispute	`setRefundRequested` (the escrow moves to `Disputed`)
A result that matches	Nothing; the seller collects after the unlock time

Every action is logged with its transaction and shows up on the purchase’s timeline.
