Map the public surface
Deltaproof checks the live catalog, product discovery, prices, policies, agent profile, and anonymous cart behavior without entering checkout.
Shopify commerce readiness, measured
Show agentswhat's true.
Deltaproof measures whether a Shopify store's public commerce surface is usable by agents, then keeps an honest receipt when an approved change makes it clearer.
A real store, not a demo
The delta tells the whole story.
The NeueTerra receipt keeps the categories that did not move beside the one that did. It proves a small catalog correction improved agent readability without claiming a broader change.
| Category | Before | After |
|---|---|---|
| Agent surface health | 15 | 15 |
| Discovery parity | 25 | 25 |
| Cart and price parity | 30 | 30 |
| Policy fidelity | 15 | 15 |
| Agent readability | 14 | 15 |

Open the evidenceA proof loop, not an audit theatre
Make the catalog easier to understand—without making things up.
Deltaproof tests a public storefront and its agent-facing surface side by side. It detects gaps, but it does not turn a recommendation into a merchant write.
Separate evidence from inference
Every report names what was measured live, what could not be observed, and the exact boundary of the probe.
Keep a verifiable delta
After an approved change, comparable runs can issue a token-gated receipt instead of a retrospective success story.
The boundary is part of the product
Useful proof does not need a buyer's data.
The live NeueTerra run used anonymous catalog and cart probes only. The checkout handoff was validated without being opened, then discarded.
- No checkout page is opened, filled, or completed.
- No buyer identity, address, payment, or order data is submitted.
- Merchant writes require an exact preview and an explicit approval.
- The receipt preserves the measured result, including unchanged categories.
