 - Test: `extension/src/service-worker/__tests__/org-vault.test.ts`
 
 **Interfaces:**
-- Consumes: `createGitHost` (`service-worker/git-host.ts`); `org_unwrap_key` (Task 1); device key from `chrome.storage.local.device_private_key`; `wasm.manifest_decrypt` (existing).
+- Consumes: `createGitHost` (`service-worker/git-host.ts`); `org_unwrap_key` (Task 1); device key from `DEVICE_STATE` via `w.get_device_info()`; `wasm.org_manifest_decrypt_filtered` (Task 5a).
 - Produces: `openOrg(cfg: OrgConfig): Promise<OrgHandleState>` where `OrgHandleState = { handle: SessionHandle; grants: string[]; offline: boolean }`; `listOrgItems(state): ManifestEntry[]` (filtered to `grants`); `getOrgItem(state, id): Promise<Item>`; `listOrgCollections(state): Collection[]`.
 
 - [ ] **Step 1: Write the failing test** (mock the GitHost + wasm boundary as `router.test.ts` does)
