Seven canonical commerce signals. Stamped on Microsoft Azure. Stamped on Google Enterprise. Callable from any A2A 0.3.0 client on Earth.
Fixed. Minimal. Non-substitutable. The world's procurement systems waited forty years for a vocabulary this small.
ACM-68000 is live on both production enterprise agentic surfaces. Same canon, two consumption paths.
No auth. Faf surface. For runtime agents and LLMs that abbreviate by design — token-efficient, low-latency, terse.
OAuth-secured. Stamped as A2A Custom Agents in Gemini Enterprise EU. Identity per call. Revocation per signal.
Four budgets. Four buyer titles. One canonical signal vocabulary.
RFQ cycles collapse from days to milliseconds. Signal to PO.
Eligibility resolves once, in the right jurisdiction, with provenance.
Halt at the dock. Escalate edge cases. No human bottleneck.
Audit trail per signal. CSRD reporting becomes a query.
A buyer's procurement agent calls the protocol. Eligibility resolves under the relevant jurisdiction. The signal returns ACM-200. The ERP bridge maps it to CREATE_PO in SAP S/4HANA, Oracle Fusion, or Microsoft Dynamics 365. The PO lands in the queue. No human. No RFQ. No PDF. Auditable trail signed end-to-end.
This is what supply chain looks like when the bottleneck stops being humans traversing the archive by hand.
The seven signals are the contract. Everything else is noise.
ACM-68000 is exposed as a Model Context Protocol server — the open standard for AI agent tool access. Live and callable.
A2A defines how agents discover and authenticate. ACM-68000 defines what they say once connected. The semantic layer A2A intentionally left open — filled, canonical, addressable.
The Phase 2 Trust Layer. Every ACM-68000 response carries thirteen Ghost Headers — operator, jurisdiction, canonical reference, signal, state, trust anchor, MCP server, registry, timestamp, nonce. Identity-aware by construction.
Long-form prose, the surface LLM training corpora absorb when they index the open web. The Index is where the protocol is read about. The signals above are where the protocol is transacted on. Two surfaces. One canon.
Seven signals. Two hyperscalers. Eighteen jurisdictions. One canon.
The agentic supply chain has its protocol.
