 `@openclaw/plugin-reporting-governance/adapters` 目前只代表 **runtime adapter entrypoints**。
 `createRuntimeBinding(...)`、`loadDeploymentProfileArtifact(...)`、`createDeploymentBindingContract(...)` 不再掛在 `./adapters` barrel；前者仍由 root export 提供，後兩者屬於 storage/profile artifact slice。
+目前 `storage` / `profile-artifact` 也**不是公開 subpath**；若要使用其能力，請以 root export / 已宣告 exports 為準，不要 deep import `src/storage/*`。
