Hunting Clawd animations

All official Clawd art lives as plain files under https://claude.ai/images/clawd/{core,persona}/…. Static assets are not Cloudflare-gated (only HTML routes are), so curl with a browser User-Agent works. The archive and inventory are in research/clawd-official/ (README.md = inventory, CLAUDE.md = format facts and classification).

Sources, in order of yield

1. Name probing. The image server answers HTTP 200 for every name: a real GIF for a valid one, an HTML catch-all otherwise. Check the magic bytes (GIF8). Seven current animations (Soccer, Basketball, Skateboard, Trumpet, Walking, Jumping, Pointing) are referenced by no shipped bundle and were found this way; Anthropic stages seasonal drops (Soccer appeared for the World Cup). Extend the PROBE list in research/clawd-official/fetch.sh with candidate names (seasons, sports, instruments, hobbies) and run it:

   research/clawd-official/fetch.sh     # re-downloads KNOWN assets, then probes; prints NEW HIT lines
   

2. The Linux desktop .deb, downloaded without installing. Its usr/lib/claude-desktop/resources/ion-dist/ is a local, greppable mirror of the claude.ai web bundles:

   curl -s https://downloads.claude.ai/claude-desktop/apt/stable/dists/stable/main/binary-amd64/Packages | grep ^Filename
   # the last line is the newest; download https://downloads.claude.ai/claude-desktop/apt/stable/<that path>, then:
   dpkg-deb -x claude-desktop_*.deb deb/
   grep -rhoE '/images/[A-Za-z0-9/_.-]+\.(gif|png|webp)' deb/usr/lib/claude-desktop/resources/ion-dist/ | sort -u
   grep -rl '"nm":"Clawd-' deb/usr/lib/claude-desktop/resources/ion-dist/   # embedded Lottie JSON
   

   Work in a scratch dir, not the repo. app.asar (npx @electron/asar extract) holds the Electron shell but no Clawd art.

3. claude.ai/code bundles in a user-captured browser HAR reference the same /images/clawd/… paths; the Laptop Lottie came from https://assets-proxy.anthropic.com/claude-ai/v2/assets/v1/<hash>.json.

4. GitHub archaeology: companion-inc/pet-clawd (earlier archive with usage notes), Mapleeeeeeeeeee/digest-showcase (preserved the Clawd-Soccer Lottie). anthropics/claude-desktop-buddy is the official BLE maker API, a separate thread.

Adding a find

New animation:
- [ ] Downloaded into research/clawd-official/, magic bytes checked
- [ ] Added to KNOWN in fetch.sh and to README.md's inventory (frames, timing, source)
- [ ] Classified per research/clawd-official/CLAUDE.md: loop, scene (idle → prop → loop → idle) or empty-stage
- [ ] Prefer a Lottie source over a rescaled, antialiased GIF when one exists
- [ ] Entry added to ANIMS in tools/convert_official_clawd.js
- [ ] Header regenerated and checked with --verify PNGs (regenerating-firmware-assets skill)
- [ ] Shown in the simulator at 480×480 and 240×240 (verifying-firmware-ui skill)

Only official art goes on the device; never draw or retouch Clawd frames.
