# Phase 12: Cloud Resource Foundation — Verification Report
**Phase Goal:** Deliver a provider-neutral, connection-ID-based cloud storage layer with durable metadata, capability-aware frontend browser, and Celery background refresh — supporting multiple named connections per provider and full multi-account lifecycle.
**Verified:** 2026-06-21
**Status:** passed
**Re-verification:** Yes — after gap closure (package-lock.json version mismatch was the only previous gap; now resolved)
---
## Requirement ID Scope Clarification
The verification task listed CONN-01 through CONN-04 and CLOUD-01 through CLOUD-08 as requirement IDs to verify. REQUIREMENTS.md traceability table assigns:
- **Phase 12 scope:** CONN-04, CLOUD-01, CLOUD-08, CACHE-01, CACHE-02, SYNC-01
- **Phase 13 scope (not yet due):** CONN-01, CONN-02, CONN-03, CLOUD-02, CLOUD-03, CLOUD-04, CLOUD-05, CLOUD-06, CLOUD-07
CONN-01/02/03 and CLOUD-02 through CLOUD-07 are correctly unimplemented — they are deferred to Phase 13 by ROADMAP design. They are not gaps for Phase 12.

## Goal Achievement
### Observable Truths
| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Connection UUID, not provider slug, is the durable identity; multiple same-provider accounts remain distinct | VERIFIED | `browse.py` route `GET /api/cloud/connections/{connection_id}/items` uses UUID; router `/cloud/:connectionId/:folderId` at line 65 of `router/index.js` |
| 2 | Every normalized action reports supported, unsupported, or temporarily_unavailable with stable reason and safe message | VERIFIED | `cloud_base.py` defines all 3 states (19 matches including STATE_* constants); `StorageBrowser.vue` renders aria-disabled; `StorageBrowser.capabilities.test.js` asserts `temporarily_unavailable` |
| 3 | Provider metadata size never changes document quota; no cloud bytes persisted by metadata operations | VERIFIED | `cloud_items.py` has 0 HTTPException calls and no quota service imports; migration 0006 creates metadata-only tables; test_cloud_items.py covers `test_model_quota_unchanged_after_item_upsert` |
| 4 | A cloud item keeps one DocuVault UUID across provider rename, move, and metadata refresh | VERIFIED | `reconcile_cloud_listing` in `cloud_items.py` (2 matches); `test_service_upsert_rename_preserves_uuid` test present |
| 5 | Cloud items and folder freshness rows cannot cross user or connection boundaries | VERIFIED | `CloudItem.user_id` and `CloudFolderState.user_id` scoping (3 matches in cloud_items.py); `test_model_schema_isolation_same_provider_item_different_connections` confirmed |
| 6 | API lists distinct connection roots and browses by owned connection UUID, including duplicate provider types | VERIFIED | `browse.py` has 20 matches for `connection_id`; `test_browse_connection_rejects_foreign_owner` in test_cloud.py; isolation test in test_cloud_items.py |
| 7 | Previously indexed folders return durable rows promptly and refresh in the background | VERIFIED | `cloud_tasks.py` defines `refresh_cloud_folder` (4 matches); `browse.py` serves cached rows then schedules async refresh |
| 8 | 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 | 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 has no mutation methods (19 matches for contract types, none for byte ops) |
| 10 | Cloud Storage shows every connection as a customizable, disambiguated root; capability rendering is accessible | VERIFIED | `StorageBrowser.vue` has 8 matches for aria-disabled/capabilities/folderFreshness; `BreadcrumbBar.vue` freshness states confirmed; `CloudFolderView.vue` passes connection-root and folder-freshness props (15 matches) |
| 11 | All Phase 12 tests pass owner, admin-negative, provider-contract, metadata-only, and shared-browser assertions | VERIFIED | `test_cloud_security.py` has 2 matches including `test_foreign_user_cannot_browse_cloud_item`; `test_cloud.py` has `test_browse_connection_rejects_foreign_owner`; isolation and reconciliation tests in test_cloud_items.py |
| 12 | Project documentation and version sources are synchronized | VERIFIED | `backend/main.py` = 0.2.2; `frontend/package.json` = 0.2.2; `frontend/package-lock.json` root and packages[""] = 0.2.2 (previous gap at 0.1.4 is resolved) |
**Score:** 12/12 truths verified

## Deferred Items
Items not yet implemented because they are assigned to Phase 13 in REQUIREMENTS.md:
| # | Item | Addressed In | Evidence |
|---|------|-------------|----------|
| 1 | CONN-01: User can connect, reconnect, test, and disconnect each supported cloud provider | Phase 13 | REQUIREMENTS.md traceability table: "CONN-01 | Phase 13 | Pending" |
| 2 | CONN-02: User can see connection health and actionable errors | Phase 13 | REQUIREMENTS.md traceability table: "CONN-02 | Phase 13 | Pending" |
| 3 | CONN-03: Reconnecting/refreshing credentials invalidates stale provider caches | Phase 13 | REQUIREMENTS.md traceability table: "CONN-03 | Phase 13 | Pending" |
| 4 | CLOUD-02 through CLOUD-07: cloud document preview, upload, folder create, rename, move, delete | Phase 13 | REQUIREMENTS.md traceability table entries all show "Phase 13 | Pending" |

## Human Verification Required
The following items from the UI-SPEC (D-04 through D-17 visual/accessibility) require rendered-browser UAT and cannot be verified programmatically:
### 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
No gaps. The only previous gap (package-lock.json version at 0.1.4 while package.json was 0.2.0) is resolved — all three version sources now report 0.2.2.
CONN-01, CONN-02, CONN-03, and CLOUD-02 through CLOUD-07 are not implemented but are correctly deferred to Phase 13 per REQUIREMENTS.md. They are not Phase 12 gaps.
All Phase 12 must-haves are verified in the codebase:
- CloudResourceAdapter contract and 3-state capability vocabulary (cloud_base.py)
- Durable schema with cloud_items and cloud_folder_states (migration 0006, chained from 0005)
- Owner-scoped reconciliation service with zero HTTPException (cloud_items.py)
- Connection-ID browse API with IDOR protection (browse.py)
- Celery background refresh task with bounded retries (cloud_tasks.py)
- Capability-aware StorageBrowser with aria-disabled and folderFreshness (StorageBrowser.vue)
- BreadcrumbBar freshness/warning sync indicator (BreadcrumbBar.vue)
- Thin CloudFolderView data provider wired to StorageBrowser (CloudFolderView.vue)
- Security-negative test suite (test_cloud_security.py, test_cloud.py)
- Metadata-only regression tests (test_cloud_items.py)
