# videocompressor.online — Design Acceptance Gate

Date: 2026-06-03
Task: t_0027eda1
Tenant: site-videocompressor-20260603
Design package: /root/.hermes/reports/site-videocompressor-20260603/design

## Verdict

DESIGN_GO

The official Stitch design package is accepted for frontend implementation. No P0 design blockers found.

This is not a local fallback approval. The accepted visual truth is the official Stitch SDK output recorded in:

- /root/.hermes/reports/site-videocompressor-20260603/design/stitch/screen-index.json
- /root/.hermes/reports/site-videocompressor-20260603/design/html/*.html
- /root/.hermes/reports/site-videocompressor-20260603/design/screens/*.png

## Gate evidence

### 1. Official Stitch evidence

PASS

Observed from `screen-index.json` and local file audit:

```json
{
  "projectId": "6425530723869486131",
  "source": "official-stitch-sdk",
  "fallback_status": "none",
  "screen_count_index": 21,
  "html_count": 21,
  "screenshot_count": 21,
  "missing_files": [],
  "issues": []
}
```

All indexed screens include `projectId`, `screenId`, `htmlUrl`, `imageUrl`, `localHtml`, and `localScreenshot`. No local fallback marker was found in the Stitch index.

### 2. Core route coverage

PASS

Core public routes have desktop and mobile Stitch screens:

```json
{
  "/": ["DESKTOP", "MOBILE"],
  "/mp4-compressor": ["DESKTOP", "MOBILE"],
  "/compress-video-for-discord": ["DESKTOP", "MOBILE"],
  "/compress-video-for-whatsapp": ["DESKTOP", "MOBILE"],
  "/compress-video-for-instagram": ["DESKTOP", "MOBILE"],
  "/privacy-video-compressor": ["DESKTOP", "MOBILE"]
}
```

Tool-state coverage is present:

```json
{
  "/state/empty": ["DESKTOP"],
  "/state/selected": ["DESKTOP"],
  "/state/processing": ["DESKTOP"],
  "/state/success": ["DESKTOP"],
  "/state/target-missed": ["DESKTOP"],
  "/state/failed": ["DESKTOP"],
  "/state/unsupported": ["DESKTOP"],
  "/state/mobile-warning": ["DESKTOP", "MOBILE"]
}
```

Acceptance note: dedicated desktop states are enough for frontend state mapping; mobile-specific handling is represented by `/state/mobile-warning` and all core route mobile screens. If frontend later adds mobile compression as a first-class flow, add mobile state variants before final QA.

### 3. Visual direction and anti-AI taste

PASS

Accepted direction: Industrial privacy-first video workstation.

Observed in screenshots:

- Dark graphite workstation shell, mint signal accents, amber primary action.
- Split hero instead of generic centered SaaS hero.
- Compressor panel is concrete and task-oriented: file, target size, resolution, quality, browser-local status.
- Layout uses dense workstation panels, tables, rails, and diagnostic cards rather than symmetric 3-column feature cards.
- Typography uses JetBrains Mono + IBM Plex Sans. No Roboto/Arial usage found. `Inter` scan hits were false positives from words like `Interaction` / `setInterval`, not font usage.
- No emoji icon usage found.
- No platform-logo pattern found in HTML scan.

Visual screenshot spot checks:

- `screens/home-desktop.png`: strong industrial/workbench identity; hero tool panel is compact and visually subordinate to the value claim; no obvious generic AI SaaS pattern.
- `screens/home-mobile.png`: single-column mobile layout, readable, no obvious horizontal overflow/cropping; primary compressor task appears near the top.
- `screens/state-success-desktop.png`: concrete result state with before/after size, preset, resolution, quality, privacy/performance notes, and clear `DOWNLOAD MP4` action.

### 4. Tool area proportion

PASS

Homepage/content-fit matrix sets the correct constraint: left value copy ~45%, right compact compressor panel ~55%, with tool panel height not exceeding left copy block by more than 1.15x.

Visual review of home desktop screenshot shows the tool panel is compact enough for a landing hero and does not become a full backend/editor console. It supports the product proof without dragging first-screen gravity away from the H1/value copy.

### 5. Mobile acceptance

PASS

Mobile screenshots exist for all core public routes. Visual spot check of `home-mobile.png`:

- Single-column flow.
- Header/top app bar first visually.
- Primary compressor task appears above/near fold.
- Preset controls and core facts remain legible.
- No obvious horizontal overflow in the screenshot.

Implementation note: some mobile HTML puts drawer `<nav>` markup after the footer as an overlay container. This is acceptable as Stitch visual truth, but frontend should implement it as a proper overlay/dialog component while preserving the same visual order: header first, footer last in the normal page flow.

### 6. Compliance / claims scan

PASS

Forbidden-claim scan across `design/html/*.html`:

```json
{
  "unlimited": 0,
  "lossless": 0,
  "no quality loss": 0,
  "support all formats": 0,
  "fastest": 0,
  "official affiliation": 0,
  "revolutionize": 0,
  "empower": 0,
  "seamless": 0,
  "cutting-edge": 0,
  "next-generation": 0
}
```

Fake paid/auth CTA scan:

```json
{
  "Sign In": 0,
  "Buy": 0,
  "Checkout": 0
}
```

Platform pages include target-language, not guarantee-language signals in HTML scan. No Discord/WhatsApp/Instagram logo pattern found.

### 7. Asset/file validation

PASS

`file` output confirms non-empty PNG deliverables:

- 21 screen PNGs exist under `design/screens/`.
- `assets/og-image.png`: 1200 x 630 PNG.
- `assets/hero-workbench.png`: 1600 x 900 PNG.
- Favicons and logo system are present under `design/assets/`.

## P0 blockers

None.

## P1 followups before production implementation

1. Replace temporary Stitch `lh3.googleusercontent.com/aida...` image references with local/self-authored assets before production. Preferred assets already exist:
   - /root/.hermes/reports/site-videocompressor-20260603/design/assets/hero-workbench.png
   - /root/.hermes/reports/site-videocompressor-20260603/design/assets/hero-workbench.svg
2. Preserve Stitch HTML/CSS as visual truth. Frontend should componentize from `design/html/*.html`, not reinterpret from screenshots or prose.
3. Implement mobile drawer as a real overlay/dialog component; keep visual top app bar first and normal footer last.
4. If the frontend promotes mobile compression beyond warning/limited mode, add mobile variants for success/failed/target-missed states before final QA.
5. Final QA must verify the real compression flow with browser Network evidence: no media upload in the default client-side workflow.
6. After WebCodecs/ffmpeg.wasm testing, calibrate copy around browser limits, file size, codec support, and target-miss expectations.
