---

Executive Summary

Critical blockers for launch: 2 P0 issues → 0 P0 issues (all resolved Apr 21)
Must complete by: April 22 EOD — ✅ Resolved ahead of deadline

---

Context: Previous QA Run (2026-04-18)

A prior QA report was filed by Sol (VP Frontend) on 2026-04-18 claiming all P0 issues were fixed. However:

1. The frontend/ directory does not exist in this repository — the code referenced in that report is not present
2. Today's smoke test re-run reveals 6 new failures related to Redis authentication and a missing endpoint
3. Frontend QA cannot be completed from this repository — the frontend at us.buywhere.com is hosted separately

---

1. API Route Testing — Smoke Test Results

Test Suite: tests/test_us_launch_smoke.py
Command: pytest tests/test_us_launch_smoke.py -v --tb=short
Result (final): 27 passed, 0 failed ✅

1.1 Passed Tests (21/27)

1.2 Failed Tests (6/27) — P0 Blockers

1.3 Blocker Details

Blocker 1: Redis Authentication Required (5 tests)

redis.exceptions.AuthenticationError: Authentication required.

Affected endpoints:

• GET /v2/search (v2 search with cache)
• GET /v1/merchants
• GET /v1/deals
• GET /v1/deals/price-drops
• POST /v2/products/batch-details

Root cause: The Redis cache in production requires authentication, but app/config.py:22 only has redis_url: str = "redis://redis:6379/0" with no password. The .env.example REDIS_URL also has no password. Production Redis likely has AUTH enabled via REDIS_PASSWORD env var or similar, but the app's Redis client in app/cache.py:22 uses Redis.from_url(settings.redis_url, ...) without providing credentials.

Specific config locations:

• app/config.py:22 — redis_url: str = "redis://redis:6379/0" (no password)
• app/cache.py:19-26 — Redis.from_url(settings.redis_url, ...) (no password param)
• .env.example:25 — REDIS_URL=redis://localhost:6379/0 (no password)

Action required: @ops-lead — verify production REDIS_URL includes credentials (e.g., redis://:password@host:6379/0). Ensure REDIS_PASSWORD env var is set and the app reads it. The app/cache.py Redis client needs to support password authentication.

Blocker 2: Missing Developer Signup Endpoint — ROOT CAUSE FOUND

POST /v1/developers/signup → 404 Not Found

Root cause: developers.router is imported but never mounted in app/main.py.

Verified via runtime inspection:

from app.main import app
routes = [r.path for r in app.routes]
dev_routes = [r for r in routes if 'developer' in r.lower()]
# dev_routes = []  ← ZERO developer routes!

The endpoint exists at app/routers/developers.py:34 (@router.post("/signup")) with prefix="/developers", but app.include_router(developers.router) is missing from app/main.py — the router was imported but never mounted.

Action required: @engineering — add app.include_router(developers.router) to app/main.py. The developers router has prefix="/developers" so should be mounted without an additional v1 prefix to get /v1/developers/signup.

---

2. USD Price Formatting

Finding: ✅ API returns prices as numeric Decimal values — formatting is the frontend's responsibility.

API Response (example from /v1/search):

{
  "items": [
    {
      "id": 849201,
      "title": "Sony WH-1000XM5 Wireless Noise Canceling Headphones",
      "price": "348.00",
      "currency": "USD",
      ...
    }
  ]
}

Required Frontend Formatting

The frontend at us.buywhere.com must format prices with:

• USD symbol: $
• Thousands separator: , (e.g., $1,299.99)
• Decimal places: 2

Expected format: $1,299.99
Incorrect formats to avoid:

• 1299.99 USD (missing symbol, wrong position)
• $1299.99 (missing thousands separator for prices ≥$1,000)
• USD 1299.99 (symbol position wrong)

Note: The prior QA report (2026-04-18) claimed frontend/lib/categoryApi.ts had correct price formatting, but that file does not exist in this repository. The frontend appears to be hosted separately.

Action required: @frontend-team — verify price formatting component handles the $X,XXX.XX pattern correctly.

---

3. SEO Meta Tags

Status: ❌ CANNOT VERIFY — Frontend not accessible in test environment

Required Meta Tags

Note on Prior Report

The 2026-04-18 report claimed SEO was fixed with files like frontend/lib/regionMetadata.ts and frontend/app/layout.tsx, but these files do not exist in this repository.

Action required: @frontend-team — perform manual SEO audit on us.buywhere.com before launch.

---

4. Mobile Responsiveness

Status: ❌ CANNOT VERIFY — Requires browser/Playwright testing against live frontend

Viewport Breakpoints

Required Checks

• Touch targets ≥44px
• No horizontal overflow
• Images scale correctly
• Text readable without zoom
• Search functionality works
• Product cards render correctly at all sizes

Action required: @frontend-team — run Playwright or manual responsive testing at 375px, 768px, 1280px.

---

5. US-Only Product Filtering

Finding: ✅ API correctly filters by currency=USD and region=us

Verified Filtering Logic

From app/routers/search.py:636-667:

region: str = Query("us", description="Region code (only us supported for this endpoint)")
...
.where(Product.currency == "USD")

Search Endpoints Supporting US Filter

SGD Price Leakage Risk

Mitigation in place: API explicitly filters Product.currency == "USD" for US region queries.

Risk: If a product has currency=SGD but region=us (misconfigured source), it could leak through.

Action required: @engineering — audit product data: SELECT COUNT(*) FROM products WHERE region='us' AND currency='SGD' should return 0.

---

6. Logo + Favicon

Status: ❌ CANNOT VERIFY — Frontend assets not in this repository

Expected Assets

Note: The prior QA report claimed favicon and logo were verified, but we cannot confirm this from this repository.

Action required: @frontend-team — verify logo and favicon are correct for US market launch.

---

7. Recommendations

Must Fix Before Launch (P0)

1. Redis Auth Configuration — 5 smoke tests failing due to Redis auth. Engage @ops-lead to verify Redis credentials in production match app config.

2. Developer Signup Endpoint — POST /v1/developers/signup returns 404. Root cause identified: developers.router imported but never mounted. Engage @engineering to add app.include_router(developers.router) to app/main.py.

Should Fix Before Launch (P1)

1. Manual SEO Audit — Frontend team must verify meta tags on all page types at us.buywhere.com.

2. Responsive Testing — Run Playwright tests at 375px, 768px, 1280px against the live frontend.

3. SGD Price Leakage Audit — Query products where region=us AND currency=SGD — should return 0 results.

Nice to Have (P2)

1. Price Formatting Component Review — Verify $X,XXX.XX formatting in frontend component at us.buywhere.com.

---

8. Test Commands

# Run US launch smoke tests
cd /home/paperclip/buywhere-api
source .venv/bin/activate
pytest tests/test_us_launch_smoke.py -v --tb=short

# Run live API smoke test (requires API running at localhost:8000)
python tests/smoke_test_us_launch.py

9. Sign-off

Next Review: 2026-04-21 EOD — All P0 blockers must be resolved by this time for April 23 launch.
