# Mobile Source Snapshot · `super-app-v1`

Read-only frozen copy of `~/Downloads/design-handoff/{mobile,shared}/` captured
**2026-05-17 · snapshot-id `snap-2026-05-17-r1`** for Path D backend build.

## What this is

The actual JSX source of `demo.pattayatogether.com` mobile app · 34 JSX + 6
shared files (~3.2 MB total). Used as the canonical source for Layer J
descriptor extraction via `v3-audit/bin/extract_descriptors.py`.

## What this is NOT

- Not the live deployment (that's `~/Downloads/design-handoff/` + Hostinger)
- Not editable from V3-AUDIT or Session C (drift control)
- Not a fork (`mobile/home.jsx` LOCK still applies to the live source)

## Contents

| Path | Count | Note |
|---|---|---|
| `mobile/*.jsx` | 34 | All screens, overlays, primitives |
| `shared/*` | 6 | `tokens.js` · `alpha35.css` · `modes.js` · `data.js` · `tweaks.js` · `atlas-map.js` |
| `MANIFEST.json` | 1 | Per-file size + sha256 + line count + snapshot metadata |
| `README.md` | 1 | This file |

## Verification

```bash
# Confirm snapshot matches the live source files:
python3 -c "
import json, hashlib
from pathlib import Path
mf = json.load(open('docs/prototypes/super-app-v1/mobile-source-snapshot/MANIFEST.json'))
for rel, meta in mf['files'].items():
    f = Path('docs/prototypes/super-app-v1/mobile-source-snapshot') / rel
    h = hashlib.sha256(f.read_bytes()).hexdigest()[:16]
    status = '✓' if h == meta['sha256_16'] else '✗ DRIFT'
    print(f'{status} {rel} · {meta[\"size_bytes\"]} bytes')
"
```

## Re-snapshot protocol

When the live prototype updates significantly (e.g., P501+ patches add new screens):

```bash
# 1. Confirm source is fresh
ls -la ~/Downloads/design-handoff/mobile/

# 2. Replace snapshot
rm -rf docs/prototypes/super-app-v1/mobile-source-snapshot/{mobile,shared}/*
cp ~/Downloads/design-handoff/mobile/*.jsx docs/prototypes/super-app-v1/mobile-source-snapshot/mobile/
cp ~/Downloads/design-handoff/shared/* docs/prototypes/super-app-v1/mobile-source-snapshot/shared/

# 3. Regenerate manifest
python3 -c "
# (see v3-audit/bin/extract_descriptors.py source for manifest regen logic)
"

# 4. Re-extract descriptors
python3 v3-audit/bin/extract_descriptors.py

# 5. Commit with bump (snap-2026-05-17-r1 → snap-YYYY-MM-DD-rN)
git add docs/prototypes/super-app-v1/mobile-source-snapshot/ docs/architecture/extracted_descriptors/
git commit -m "chore: re-snapshot prototype · snap-YYYY-MM-DD-rN"
```

CI gate (TODO Slice 2+): block PR if descriptor extraction would produce
different output than committed `extracted_descriptors/` · forces conscious
snapshot bumps.

## Output

The extractor produces `docs/architecture/extracted_descriptors/{screen_id}.json`
for each screen found. Layer J `layout_composer` consumes these instead of
hardcoding component trees — backend = 100% from prototype reality.
