# Phase 12 — Validation Strategy

> Post-execution validation contract and Nyquist audit evidence for the cloud resource foundation.

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | pytest 9.x, Vitest 4.x, Vue Test Utils 2.x |
| **Config file** | `backend/pytest.ini`, `frontend/vitest.config.js` |
| **Quick backend command** | `docker compose run --rm backend pytest -q tests/test_cloud.py tests/test_cloud_backends.py tests/test_cloud_capabilities.py tests/test_cloud_items.py tests/test_cloud_security.py` |
| **Quick frontend command** | `cd frontend && npm test -- --run src/components/storage/__tests__/StorageBrowser.capabilities.test.js src/components/ui/__tests__/BreadcrumbBar.test.js src/views/__tests__/CloudFolderView.test.js src/views/__tests__/CloudStorageView.test.js src/stores/__tests__/cloudConnections.test.js src/components/settings/__tests__/SettingsCloudTab.test.js` |
| **Full suite command** | `cd backend && pytest -v`; `cd frontend && npm test`; `cd frontend && npm run build` |
| **Fresh focused runtime** | Backend 155 tests in 4.14 s; frontend 62 tests in 703 ms (2026-06-19) |

---

## Sampling Rate

- **After every task commit:** Run the focused test file(s) named by that task.
- **After every plan wave:** Run backend and frontend suites for all touched layers.
- **Before `/gsd:verify-work`:** Run the full backend suite, full frontend suite, production build, and required PostgreSQL integration tests.
- **Max observed focused feedback latency:** 4.14 seconds, excluding container startup.

## Requirement Coverage

| Requirement | Status | Automated evidence |
|-------------|--------|--------------------|
| CONN-04 | COVERED | Capability contract tests, connection store/settings tests, StorageBrowser action-state tests |
| CLOUD-01 | COVERED | Connection-ID API tests and shared CloudStorageView/CloudFolderView/StorageBrowser tests |
| CLOUD-08 | COVERED | Unsupported/temporarily-unavailable state, message, pointer, Enter, Space, and touch suppression tests |
| CACHE-01 | COVERED | No-MinIO, no-byte-download, no-quota-mutation browse/refresh tests |
| CACHE-02 | COVERED | Cloud metadata/extracted text/topic/semantic fields and cross-connection isolation tests |
| SYNC-01 | COVERED | Provider normalization plus durable item/reconciliation/freshness tests |

---

## Wave 0 Requirements

- [x] `backend/tests/test_cloud_capabilities.py` — capability normalization, reason states, safe discovery, item overrides.
- [x] `backend/tests/test_cloud_items.py` — owner-scoped persistence, stable identity, reconciliation, metadata-only invariants.
- [x] Database constraint/isolation coverage for UUID ownership, unique connection/item identity, and cascade behavior.
- [x] `CloudFolderView.test.js` and `CloudStorageView.test.js` — thin shared-browser view integration.
- [x] Provider response fixtures for Google Drive, OneDrive, Nextcloud, and generic WebDAV normalization.
- [x] Focused runtime baseline recorded: backend 4.14 s, frontend 703 ms, excluding container startup.

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Tooltip placement and clarity across desktop/mobile viewports | CLOUD-08 | Visual placement and viewport clipping require a rendered browser | Hover and keyboard-focus a gray/amber cloud action on desktop, then tap it on mobile; verify readable explanation, no overlap, and no underlying action |
| Cached-first transition and freshness presentation | CLOUD-01, SYNC-01 | Perceived flicker, layout stability, and continued row usability are visual qualities | Seed durable metadata, delay/fail provider refresh, navigate the folder, and verify rows remain interactive while refreshing/warning indicators and last-update copy render correctly |

These checks supplement automated coverage; no Phase 12 requirement depends solely on manual verification.

### Fresh Execution Evidence

- Backend focused cloud suite: **155 passed**, 1 non-failing SlowAPI deprecation warning, 4.14 s.
- Frontend focused cloud/UI suite: **62 passed** across 6 files, 703 ms.
- Execution closeout evidence: backend 509 passed with one documented environment-only `libmagic` failure; frontend 323 passed; production build succeeded.
- Phase verification: `.planning/phases/12-cloud-resource-foundation/12-VERIFICATION.md` status `passed`, 12/12 must-haves verified with one documented package-lock tracking override.

---

## Validation Sign-Off

- [x] Every Phase 12 requirement has targeted automated verification.
- [x] Every executed task has automated or explicit source/security evidence.
- [x] Sampling continuity contains no three-task gap.
- [x] Wave 0 files and fixtures exist.
- [x] Commands use one-shot test modes, not watch mode.
- [x] Focused feedback latency is below 60 seconds.
- [x] `nyquist_compliant: true` is set in frontmatter.
