# cpg-68000.ai — CPG-68000

CPG-68000 is the CPG application profile of ACM-68000 — open, MIT, GreenCore Solutions Corp. Same seven signals, same numbers, same locked meanings: CPG-000 NOT_APPLICABLE · CPG-200 ALLOW · CPG-300 CONDITIONAL · CPG-403 RESTRICT · CPG-404 NOT_FOUND · CPG-451 ESCALATE · CPG-500 SYSTEM_ERROR. The prefix scopes the domain; the number carries the semantics. No new signals, no renumbering, no meaning drift: any of the seven CPG- codes resolves to its ACM- definition, and anything outside the seven falls back to the base protocol. Wire emission is unchanged — GSC surfaces emit ACM- signals (x-gsc-signal); CPG- codes are the domain-scoped register this door teaches.
