Summary

Adds a second bundled pet to MiniMax Pet: MiniMax Code 章鱼娘 (minimax-tako), an original chibi octopus girl with pink hair, round glasses, a red sound-wave hair clip, a white blouse with a wine-red bow, and wine-red tentacles with pink suckers. Bumps the plugin to 0.5.9.

• New atlas: miniapp/client/pets/minimax-tako/{pet.json,spritesheet.png}, v2, 1536 × 2288. It has all 9 animation rows (idle, running right/left, waving, jumping, failed, waiting, working, review) and 16 look directions.
• No runtime code changes. The bundled catalog already scans miniapp/client/pets/. The id sorts after minimax-original, so the mint robot stays the default pet for fresh profiles.
• Source first, then npm run package and copied into plugins/minimax-ai/minimax-pet. npm run check:package reports an exact byte match (36 files).
• Docs: ARTWORK.md, PROVENANCE.md, README.md and README.zh-CN.md describe how the atlas was made and its license (MIT, MiniMax).

How the artwork was made

MiniMax image generation produced a character sheet, per-animation frame grids and nine gaze poses on a chroma-key background. User-provided images were used as visual references for proportions and colors; the references are not bundled. A local script removed the background, sliced the frames, normalized scale and foot baseline, and assembled the exact grid. The left-running row and the left look directions are mirrored from the right side. Generation is not deterministic, so the PNG itself is the source (no generate:art equivalent).

Tests

• dev/pet-art-validation.test.mjs: the shipped minimax-tako atlas passes the packaged Skill validator, ok: true with 73 frames and no warnings.
• dev/smoke-api.mjs: /api/pets lists both bundled pets in id order with minimax-original first. Each bundled pet.json and spritesheet is served as a v2 PNG. The imported-after-bundled listing is updated.

Verification

• npm test (source): 254/254 pass.
• npm run test:smoke: the new and updated cases pass. 3 cases fail identically on clean origin/main (reproduced 4/4 runs on main, Node v26.4.0), so they are pre-existing and unrelated to this change:
  • image-header: bundled first-party PNG is 1536x2288 (v2) and GET bundled spritesheet via /assets compare the committed robot PNG byte-for-byte with a fresh encode (55289 vs 55307 bytes, zlib output differs on this Node).
  • traversal/invalid "/assets/../node/server.mjs" fails intermittently with ECONNRESET.
• npm run check:package: exact byte match.
• Root npm run check: 87/87 tests pass; plugins/minimax-ai/minimax-pet: OK.
• Character consistency, motion and gaze direction were reviewed visually. The validator cannot judge them.

Not verified

• Installing this exact build in a released MiniMax Code client and opening the bundled pet from the gallery.
• Windows GUI.
