What it enforces

Escalates refunds above the threshold into the named approver's queue.
Reviewer authority check
Blocks an approval from a reviewer whose authority limit is below the amount.
Duplicate-claim guard
Restrains a refund whose claim reference has already been settled.

How to install it
Installs with no code. The Decionis app sits beside Slack approvals and records a Decision Dossier for every routed request.

1. Install Decionis from the Slack Marketplace.
2. /decionis → "Connect a workflow" → pick refund_approval (or any of the starter packs).
3. The app runs in observation mode out of the box: every Slack approval still
flows the same way, plus a signed Decision Dossier is recorded alongside it.Install the Slack appShips in shadow mode — every verdict is recorded, nothing is blocked.
