Adobe Commerce Price-Drift Circuit Breaker
Catches a pricing feed or AI engine publishing a price far off the last-known-good value before shoppers see it.
For: Merchandising and pricing teams on Adobe Commerce
SOC 2 CC8.1ISO 27001 A.8.34Pricing change evidence
What it enforces
Drift ceiling
Blocks a price update that moves more than the allowed percentage from the last approved price.
Below-cost block
Blocks any published price at or below the item's cost basis.
Bulk-update restraint
Restrains a feed run that would reprice more SKUs than the batch ceiling allows.

Fork it, change the thresholds to match your environment, and deploy in shadow mode first — it defaults to listen-only so nothing in your live pipeline changes.
How to install it
Follow the install path for this surface, then paste the forked YAML as your policy config.
What to do next
This recipe is one step in a path. The same five steps apply to every recipe in the exchange.
- Simulate this recipe
Run the policy against a realistic action in the browser. Push it past what the rules allow and watch the verdict come back. No account.
- View the signed Decision Dossier
See exactly what was decided and why: the rule that fired, the evidence it read, the policy version in force, and an Ed25519 signature you can verify yourself.
- Deploy in shadow mode
Measure what the policy would have caught on your own traffic without touching the live path. Every recipe defaults to shadow, so the first deployment carries no execution risk.
- Connect a real workflow
Point the same policy at the system where the action actually originates — a checkout, an ERP posting, a Zap, an agent's tool call.
- Share the verified result
Publish the proof: a public verification link, an embeddable badge, a PR comment, or an anonymized shadow-mode finding. This is how the next person discovers Decionis.
