# cpg-68000.ai — CPG-68000

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.

Signals: ACM-000=NOT_APPLICABLE (GTIN 990832300785) · ACM-200=ALLOW (GTIN 990832300778) · ACM-300=CONDITIONAL (GTIN 990832300761) · ACM-403=RESTRICT (GTIN 990832300754) · ACM-404=NOT_FOUND (GTIN 990832300747) · ACM-451=ESCALATE (GTIN 990832300730) · ACM-500=SYSTEM_ERROR (GTIN 990832300723)

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.
