# OACP Offline POS Bridge Boundary

> How Grantex treats Offline POS handoff evidence without owning POS transactions.

# OACP Offline POS Bridge Boundary

Canonical end-to-end flow: [OACP authority overview](./overview).

AgenticOrg owns Offline POS Bridge orchestration. POS systems and payment providers own final price, inventory, staff review, payment, receipt, and order evidence. Grantex only recognizes non-sensitive evidence references when they are needed for OACP policy or authority refresh.

## Ownership

| Area                      | Owner                  | Grantex role                                                                      |
| ------------------------- | ---------------------- | --------------------------------------------------------------------------------- |
| POS handoff packet        | AgenticOrg             | Verify that referenced OACP artifacts and policy boundaries are valid when asked. |
| Final POS price/inventory | POS or merchant system | Treat as source-of-record evidence, not as Grantex state.                         |
| Payment confirmation      | POS/payment provider   | Accept only redacted evidence refs; never store raw payment payloads.             |
| Receipt evidence          | POS/payment provider   | Reference only when callback evidence is verified.                                |
| Policy refresh            | Grantex                | Issue or refuse refreshed OACP artifacts from public-safe evidence.               |

## Allowed Evidence

OACP artifacts may carry references such as:

* `offline_pos_handoff_packet_ref`
* `provider_pos_evidence_ref`
* `receipt_evidence_ref`
* catalog, price, inventory, policy, and mandate capability artifact refs

The references must be non-sensitive, scoped to tenant/merchant/seller agent, and tied to freshness metadata. They are not proof that a payment succeeded unless the POS or provider callback says so.

## Blocked Claims

Grantex does not:

* execute a POS transaction;
* capture a POS payment;
* create a POS order;
* reserve in-store inventory;
* verify raw card, wallet, mandate, or provider payloads;
* turn a simulator confirmation into a live paid state.

## Safe Wording

Use:

> POS accepted the handoff. Staff must confirm final price and payment at the store.

Do not use:

> OACP completed the POS purchase.

## Runtime Status

AgenticOrg has an internal Offline POS Bridge foundation with non-sensitive handoff packets, confirmation intake, local simulator confirmation, and reconciliation status. Live POS integrations require merchant/POS provider approval, verified callbacks, monitoring, rollback, and operator readiness.
