{"standard":"CPG-68000","title":"CPG-68000 — the seven-signal procurement protocol for AI Agents (gen-2 door)","what":"CPG-68000 is the NextGen door for GSC's deterministic procurement signal protocol: seven signals, one meaning each, GS1-anchored (each signal carries a GSC-registered GTIN), append-only, non-substitutable. A buyer-side AI Agent reads one signal and knows what to do — execute, evaluate, halt, abort, escalate to a human. Canon value on the wire stays ACM-68000 (header x-gsc-protocol); the full canon resolves on acm-68000.ai / acm-68000.org and the standards beacon.","parent_gtin":"990832300716","canon":{"ai":"https://acm-68000.ai","org":"https://acm-68000.org","beacon":"https://mcp.cpgagentprotocols.ai/mcp","beacon_tools":["list_signals","resolve_signal","get_protocol"]},"scope":"Apex family only (cpg-68000.ai/.com/.io/.org). The 28 signal-door zones (acm-000 … acm-500 × four TLDs) remain on the ACM-68000 canon until the ACM redo program ships — CEO-sequenced.","spine":["SM-AIO-CPG","SM-ESG-CPG","CPG-68000","IA-MESSAGE"],"signals":[{"code":"ACM-000","state":"NOT_APPLICABLE","gtin":"990832300785","action":"No action required."},{"code":"ACM-200","state":"ALLOW","gtin":"990832300778","action":"Execute the transaction."},{"code":"ACM-300","state":"CONDITIONAL","gtin":"990832300761","action":"Evaluate before proceeding."},{"code":"ACM-403","state":"RESTRICT","gtin":"990832300754","action":"Halt transaction."},{"code":"ACM-404","state":"NOT_FOUND","gtin":"990832300747","action":"Abort transaction."},{"code":"ACM-451","state":"ESCALATE","gtin":"990832300730","action":"Route to a human."},{"code":"ACM-500","state":"SYSTEM_ERROR","gtin":"990832300723","action":"Retry or escalate."}],"doors":{"instant_messaging":{"lane":"agents","inbound":"https://x-gsi.ai/ingest","mcp":"https://mcp.cpghumanintheloop.ai/mcp"},"trading_desk":{"lane":"humans","url":"https://gsc-navigator.ai/","informed_by":"Navigator"}},"operator":"GreenCore Solutions Corp.","duns":"24-336-6774","posture":"free — x402 declared as capability (x-gsc-x402: ready), no terms"}
