# Final Production Sign-Off — MVNexus Agile Analytics

**Date:** 2026-06-05
**Cycle:** Release Candidate Lock (feature scope frozen)
**Decision owner:** Engineering / QA
**Evidence:** `docs/RELEASE_CANDIDATE_QA_REPORT.md` + `docs/uat-screenshots/`

---

## Decision

# ✅ GO for controlled production pilot

All release-candidate gates are verified with evidence. Two defects found during this QA pass
were fixed and re-verified. The single remaining limitation (legacy Arabic translation debt) is
**non-blocking** because the app falls back to English for untranslated keys.

> This sign-off authorizes a **controlled pilot** (limited cohort, monitored). It is **not** an
> unconditional full-scale GA. See "Pilot conditions" and "Known limitations" below.

| No console errors during E2E/UAT | ✅ | 0 across 14 surfaces (capture harness) |
| No failed API responses during E2E/UAT | ✅ | 0 (`/api/` status ≥ 400) |
| UAT screenshots reviewed manually | ✅ | 45 images across core/responsive/dark/i18n |
| Responsive at 1440 / 768 / 390 | ✅ | `docs/uat-screenshots/responsive/` |
| Dark mode: charts/cards/modals/tabs intact | ✅ | `docs/uat-screenshots/dark/` |
| AR/EN parity for all **changed labels** | ✅ | refactor-section missing AR keys = 0 (222 added) |
| Permissions: viewer/member/manager/admin | ✅ | 4 role assertions pass |

## Defects found and resolved this cycle

| # | Defect | Severity | Resolution | Status |
|---|---|---|---|---|
| 1 | Overview `OverviewNavCard` rendered `<ul>` inside `<p>` (hydration/nesting error) | Medium (real) | `Hint` `styled.p` → `styled.div` | ✅ Fixed + verified |
| 2 | Capacity page crash on missing `team` in response | Medium | Defensive empty-state guard + corrected E2E mock | ✅ Fixed + verified |

No new features were added; scope stayed frozen.

## Pilot conditions

1. Pilot with a **limited, monitored cohort**; keep error monitoring (console + API) enabled.
2. Ensure the live backend `/projects/{id}/capacity-planning` returns the
   `{ sprint, metrics, team[] }` contract; the UI now degrades gracefully if not, but capacity
   planning requires it to be functional.
3. Run a manual smoke on **WebKit/Firefox** during the pilot (automated runs were Chromium).

---

## Known limitations (non-blocking)

1. **Arabic localization debt in legacy sections** (~194 keys: `capacity`, `backlog`, `sprints`,
   `planning`, `workItem`, `closure`, `lifecycle`, `board`, `nav.capacity`). These predate this
   cycle and render English via `fallbackLng: 'en'`. The **changed labels** introduced by the
   Agile UX & Analytics refactor are fully translated. Schedule a follow-up localization pass.

## Sign-off statement

The MVNexus Agile Analytics module has passed all required automated suites and the
release-candidate QA gates (console-clean, failed-response-clean, responsive, dark mode,
permissions, and changed-label localization), with all evidence captured and manually reviewed.
Two defects were identified and fixed during this pass.

**Result: GO for controlled production pilot**, subject to the pilot conditions above.
