# Fixture Manifests > Status: draft | Updated 2026-07-06 | Applies to: AMPB and AMPG compatibility checks AMPB can check AMPG fixture manifests without contacting any network. The check confirms that each generated fixture URL routes to the expected AMPB transport and profile. ## Command ```sh python3 -m ampbrowser fixture check ../adaptive-multi-protocol-gateway/dist/wownero/ampg-fixture-manifest.json ``` The command exits non-zero when any fixture route does not match the manifest. ## Scope Fixture checks validate route selection only. They do not verify daemon health, hidden service reachability, IPFS pinning, TLS, or content freshness. The manifest must not contain private deployment notes, service keys, credentials, or host inventory.
