OACP Offline POS Bridge Boundary

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

Canonical end-to-end flow: OACP authority 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

The protocol_adapter artifact’s offline_pos_bridge_mapping names the reference types a POS handoff may use:

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

The policy_scope artifact states that these refs are allowed. No POS evidence reaches Grantex today, so the mandate_capability artifact says offline_pos_evidence_status: "unverified" and names no POS reference (an earlier placeholder value was removed). 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.
