# Why Grantex Is Not A Transaction Toll Booth

> Why OACP authority signs artifacts without relaying every buyer and seller interaction.

# Why Grantex Is Not A Transaction Toll Booth

## Summary

Grantex is the OACP authority, not a relay for every buyer message. Valid cached artifacts let AgenticOrg answer non-binding questions while commitment requests remain gated by merchant, provider, bank, POS, and channel evidence.

## Target Audience

Architects, operators, and platform buyers.

```

## End-To-End Flow

Grantex signs the trust artifact. AgenticOrg stores a scoped cache. Buyer questions use the cache until freshness or revocation fails. Purchase requests must use approved merchant/provider/bank/POS/channel paths and cannot be converted into success by cache alone.

## What Is Implemented Now

The authority endpoint issues/refuses artifacts. AgenticOrg cache and bridge routes consume them for Q\&A and prepared handoff. AgenticOrg merchant config records Shopify runtime setup plus WooCommerce/ERP/bank/custom provider pending-adapter intent without making Grantex the config owner.

## What Requires External Approval Or Config

Public tenant launch, provider or bank rail execution, POS callback approval, and channel rollout.

## Failure Modes

* Cache used past TTL.
* Commitment request treated like a discovery request.
* Grantex outage misunderstood as permission to execute.

## Safe User Wording Examples

* "Grantex signed the source artifact; AgenticOrg answered from valid cache."
* "A valid cache supports discovery, not payment authority."
* "This request needs provider or merchant approval before execution."
