# CPG-68000 — the CPG application profile of ACM-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 CPG-XXX resolves to its ACM-XXX 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.

## Signals

- CPG-000 = ACM-000 NOT_APPLICABLE · GTIN 990832300785 · No action required.
- CPG-200 = ACM-200 ALLOW · GTIN 990832300778 · Execute the transaction.
- CPG-300 = ACM-300 CONDITIONAL · GTIN 990832300761 · Evaluate before proceeding.
- CPG-403 = ACM-403 RESTRICT · GTIN 990832300754 · Halt transaction.
- CPG-404 = ACM-404 NOT_FOUND · GTIN 990832300747 · Abort transaction.
- CPG-451 = ACM-451 ESCALATE · GTIN 990832300730 · Route to a human.
- CPG-500 = ACM-500 SYSTEM_ERROR · GTIN 990832300723 · Retry or escalate.

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.
