# Phase 12: Cloud Resource Foundation — Verification Report

**Phase Goal:** Establish a provider-neutral cloud resource contract and durable metadata foundation enabling all 4 providers (Google Drive, OneDrive, Nextcloud, WebDAV) to expose owner-scoped, connection-ID-based folder browsing with stale-while-revalidate semantics and capability-aware frontend rendering — all without downloading file bytes, mutating quota, or implementing Phase 13 mutations.
**Verified:** 2026-06-19
**Status:** gaps_found — 1 blocker (package-lock version mismatch)
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | D-02/D-03: connection UUID, not provider slug, is the durable identity and multiple same-provider accounts remain distinct | VERIFIED | `backend/api/cloud/browse.py` route `GET /api/cloud/connections/{connection_id}/items` uses UUID; `backend/storage/cloud_base.py` contract; router `/cloud/:connectionId/:folderId` in `frontend/src/router/index.js` |
| 2 | D-08/D-09/D-10: every normalized action reports supported, unsupported, or temporarily_unavailable with a stable reason and safe message | VERIFIED | `cloud_base.py` lines 41-43 define all 3 states; `StorageBrowser.vue` renders aria-disabled for non-supported states; `StorageBrowser.capabilities.test.js` asserts `temporarily_unavailable` |
| 3 | D-18: provider metadata size never changes document quota and no cloud bytes are persisted by metadata operations | VERIFIED | `cloud_items.py` line 6 comment confirms no quota service calls; no `used_bytes` mutations in service; `test_model_quota_unchanged_after_item_upsert` in test_cloud_items.py |
| 4 | A cloud item keeps one DocuVault UUID across provider rename, move, and metadata refresh | VERIFIED | `reconcile_cloud_listing` in `backend/services/cloud_items.py`; `test_service_upsert_rename_preserves_uuid` test |
| 5 | Cloud items and folder freshness rows cannot cross user or connection boundaries | VERIFIED | `cloud_items.py` owner-scoped queries (CloudItem.user_id == uid_v2, CloudFolderState.user_id == uid_fs); `test_model_schema_foreign_owner_query_returns_nothing` and `test_service_list_children_owner_scoped` |
| 6 | D-01/D-02/D-03: API lists distinct connection roots and browses by owned connection UUID, including duplicate provider types | VERIFIED | `browse.py` `GET /api/cloud/connections/{connection_id}/items`; `test_browse_connection_rejects_foreign_owner` in test_cloud.py; `test_model_schema_isolation_same_provider_item_different_connections` |
| 7 | D-11/D-12: previously indexed folders return durable rows promptly and refresh in the background | VERIFIED | `backend/tasks/cloud_tasks.py` `refresh_cloud_folder` task; `browse.py` serves cached rows then schedules async refresh |
| 8 | D-13/D-14: successful refresh reconciles silently; failures retain cached rows, warning state, last-success time, and bounded retries | VERIFIED | `test_refresh_cloud_folder_failed_refresh_retains_cached_rows` and `test_service_reconcile_incomplete_does_not_delete` in test_cloud_items.py |
| 9 | D-18/CACHE-01: browse and refresh never download file bytes, write MinIO, or mutate quota | VERIFIED | No `get_object`/MinIO calls in browse.py or cloud_tasks.py; cloud_base.py adapter interface has no mutation methods |
| 10 | D-01/D-03/D-04/D-05/D-06/D-07: Cloud Storage shows every connection as a customizable, disambiguated root; capability rendering is accessible | VERIFIED | `StorageBrowser.vue` props: capabilities, folderFreshness, connectionRoot; `BreadcrumbBar.vue` folderFreshness states (refreshing/fresh/stale); aria-disabled rendering confirmed |
| 11 | All six Phase 12 requirements pass owner, admin-negative, provider-contract, metadata-only, and shared-browser tests | VERIFIED | `test_cloud_security.py` with `test_foreign_user_cannot_browse_cloud_item`; full test suite including test_cloud_backends.py, test_cloud_capabilities.py |
| 12 | Project documentation and phase-completion version are synchronized with shipped behavior | FAILED | `backend/main.py` = 0.2.0 (PASS), `frontend/package.json` = 0.2.0 (PASS), `frontend/package-lock.json` root and packages[""] = **0.1.4** (FAIL) |

**Score:** 11/12 truths verified

## Behavioral Spot-Checks

| Behavior | Command | Result | Status |

## Human Verification Required

None identified for the automated scope. The following items from the UI-SPEC (D-04 through D-17 visual/accessibility) require rendered-browser UAT per Plan 12-04 Task 2, but are outside automated code verification scope:

### 1. Tooltip and touch-tap capability explanation

**Test:** On desktop, hover over a grayed-out action in StorageBrowser when browsing a cloud folder. On mobile, tap the action.
**Expected:** Tooltip appears on hover/focus; dismissible inline notice appears on tap. No action fires.
**Why human:** CSS tooltip appearance and touch event suppression require a rendered browser.

### 2. Freshness indicator fade behavior

**Test:** Navigate to a freshly refreshed cloud folder and watch the "up to date" checkmark.
**Expected:** Checkmark fades after 3 seconds without causing a layout shift.
**Why human:** CSS transition timing and layout shift require visual inspection.

### 3. Warning state copy and last-refresh timestamp

**Test:** Simulate a failed provider refresh and observe the BreadcrumbBar warning banner.
**Expected:** Banner shows exact UI-SPEC copy with relative last-refresh time; cached rows remain interactive.
**Why human:** Dynamic relative-time rendering and interactive row state require rendered browser.

---

## Gaps Summary

One blocker was found: `frontend/package-lock.json` has not been updated from `0.1.4` to `0.2.0`. Both the root-level `version` field and the `packages[""]` entry remain at `0.1.4`. Plan 12-04 Task 3 explicitly requires all three version sources (backend/main.py, frontend/package.json, frontend/package-lock.json) to equal `0.2.0`. The package.json itself is correct at `0.2.0`; the lock file was not regenerated after the version bump.

**Fix:** Run `cd frontend && npm install` (which regenerates package-lock.json honoring package.json) or manually update both occurrences of `0.1.4` in package-lock.json to `0.2.0`.

All other phase-12 must-haves — the CloudResourceAdapter contract, durable schema (migration 0006), owner-scoped reconciliation service, provider adapter normalization, connection-ID browse API, Celery refresh task, capability-aware StorageBrowser, BreadcrumbBar freshness, security-negative test suite, and documentation — are verified in the codebase.
