## Verdict

FRONTEND_IMPLEMENTED_AND_DEPLOYED_WITH_DNS_RESIDUAL.

The P0 frontend is implemented, committed, pushed, deployed to Cloudflare Pages production from the same commit, and verified on the Pages production URL. The fixed apex domain `https://videocompressor.online/` is attached as a Pages custom domain but currently returns Cloudflare 522 / custom-domain validation pending because the Cloudflare zone is still pending nameserver activation and Pages reports `CNAME record not set`.

## Production URLs

- Production Pages URL: https://videocompressor-32j.pages.dev/
- Deployment URL: https://f08401ca.videocompressor-32j.pages.dev
- Fixed domain: https://videocompressor.online/ — currently 522 / pending DNS+custom domain validation

## Product implementation

- Next.js 16 App Router static export for Cloudflare Pages.
- Official Stitch design package copied into `design-v3/` and visual system translated into React components.
- Dark industrial privacy-first design tokens retained: `#0B0E0D`, `#131A18`, `#18221F`, `#EAF2EE`, `#8DA39A`, `#7CFFB2`, `#FFB84D`.
- Fonts match handoff intent: JetBrains Mono for mono/display accents, IBM Plex Sans for body.
- Local-first video compressor UI includes file selection, target size, presets, resolution, quality, progress, cancel, success, target-missed, failed, unsupported, and download states.
- Presets implemented: Discord 10MB, WhatsApp 16MB, Email 25MB, Instagram quality/resolution, custom MB.
- Compression uses browser-local ffmpeg.wasm and produces MP4 output with H.264/AAC command path when supported.
- Analytics integration is Plausible-only with safe bucketed product events. It does not send filenames, paths, thumbnails, media content, or exact media metadata.
- Privacy/Terms copy follows compliance v0 and uses `support@videocompressor.online`.
- No fake login, Stripe, checkout, official-affiliation claims, `unlimited`, `lossless`, `no quality loss`, or `supports all formats` claims.

## Verification

Commands run:

```bash
npm run lint
npm run typecheck
npm run build
npm run verify
```

Result:

- lint passed with 2 non-blocking `@next/next/no-img-element` warnings for local SVG logo assets.
- typecheck passed.
- build passed; 13 static pages generated.
- route-contract verification passed for all P0 routes, sitemap, robots, headers, OG, favicon.
- Local static preview returned HTTP 200 for all P0 routes and `sitemap.xml` / `robots.txt`.
- Browser verification on `https://videocompressor-32j.pages.dev/` loaded title `Video Compressor Online — Private Browser MP4 Compression`.
- Browser verification on `/mp4-compressor/` loaded title `MP4 Compressor — Browser H.264 Video Compression | videocompressor.online`.
- Browser verification on `/privacy/` loaded title `Privacy Policy | videocompressor.online`.
- 390px mobile browser check: no horizontal overflow; primary touch targets measured >=44px.
- Local Playwright functional check with generated 1-second MP4: file upload enabled Start Compression, local compression completed, download link appeared, no media upload request observed. Non-local network was limited to allowed static/analytics/ffmpeg engine loading; blob requests were local browser object URLs.

## Cloudflare deployment

- Pages project created: `videocompressor`
- Production branch: `main`
- Production deployment: `https://f08401ca.videocompressor-32j.pages.dev`
- Canonical Pages subdomain: `https://videocompressor-32j.pages.dev/`
- Deployment source commit: `613eacab43048e1e5ac3af0f714d97eccab32fe5`
- Custom domain API attach: `videocompressor.online`, status `initializing`
- DNS records created in Cloudflare zone:
  - `videocompressor.online CNAME videocompressor-32j.pages.dev proxied`
  - `www.videocompressor.online CNAME videocompressor-32j.pages.dev proxied`

## Residual risks / next gates

1. Fixed apex domain is not live yet. `https://videocompressor.online/` currently returns 522. Cloudflare zone file shows `zone_status=pending`; registrar nameservers still need to resolve to `coraline.ns.cloudflare.com` and `nico.ns.cloudflare.com`, then Pages custom-domain validation should be rechecked.
2. ffmpeg.wasm engine is loaded from `unpkg.com/@ffmpeg/core` at runtime; this keeps media local but adds external static engine dependency. If strict first-party-only assets are required, vendor the ffmpeg core files into `public/` in a follow-up.
3. Browser compression is verified on a tiny generated MP4. Larger real-world videos still need QA on desktop Chrome/Edge and mobile warning paths.
4. Plausible script is integrated, but dashboard-side site creation / event receipt was not independently verified in this run.
