# Distribution channels

> Publish one Darwin Supply catalog through verified seller channels without creating duplicate inventory.

Channels distribute controlled projections of the same Supply business and catalog. They do not create a second source of truth.

| Channel        | Protocol   | Current status | Primary requirement                                                                              |
| -------------- | ---------- | -------------- | ------------------------------------------------------------------------------------------------ |
| Darwin network | Darwin API | Available      | Active seller profile and eligible listings.                                                     |
| ChatGPT        | ACP        | Preview        | Valid feed and checkout behavior, policy review, and provider approval.                          |
| Gemini         | UCP        | Preview        | Verified profile, supported capabilities, merchant and payment readiness, and provider approval. |
| AI clients     | MCP        | Preview        | Production MCP deployment, Darwin OAuth, and scoped tool verification.                           |

## Readiness model

Each channel reports a set of technical and business checks. `Ready` means the known Darwin-side prerequisites pass. `Awaiting approval` means an external provider decision is still required. Only a verified production connection can report `Live`.

## Source-of-truth rule

Edit business and catalog data in Darwin Supply. Channel adapters should preserve Darwin identifiers, revisions, and provenance so retries remain idempotent and reconciliation can explain every external projection.
