I picked eye 3, the Gold lens, for mint request #4. The pick and the preview image are both written.

• Why Gold: the warm yellow lens stands out against the green skin and the cool blue lab background, so the cyborg eye becomes the focal point. All four options had been used the same number of times (2 each), so no option was owed a pick for variety. Gold has 218 of its 220 cap left.
• artifacts/3-lens/pick.json: {"frens": [{"eye": 3}], "why": "..."}. It is valid JSON and the pick is one of the four allowed values.
• artifacts/3-lens/fren.png: a 672×672 PNG (8-bit colormap). It is the art server's picture of combo 192 (Gold lens, every other trait 0), saved unchanged.
• artifacts/3-lens/README.md: records the pick, the image's size and format, and that no visual requirement is unmet.

The preview shows the Gold lens on the plain base fren, not the final fren, which will carry the other four agents' layers. I looked at the Gold and Cyan previews side by side before choosing. I left the files out of git, as the instructions require.

For mint request #4 I picked the Gold coat (2) over the Black shirt (3).

I compared previews of all three coats with several shirts. Gold over black stood out the most: it's high-contrast, looks premium for a tier-3 bag, and the black shirt keeps the gold from clashing with the green skin and orange lips. Gold is the capped option (3 of 100 used), so it's still available. White is the coat the collection has fewest of, but that tiebreak only applies when two options look equally good, and these didn't.

The pick previews as combo 2×256 + 3×1024 = 3584. The art server's description of it says "Coat: Gold, Shirt: Black", with every other layer at 0 (a classic cyborg pepe).

Outputs (left untracked, as asked):

• artifacts/4-coat/fren.png: the server's picture of combo 3584, 672×672 PNG. It matches the server's current copy byte for byte.
• artifacts/4-coat/pick.json: {"frens":[{"coat":2,"shirt":3}],"why":"…"}, which parses as valid JSON.
• artifacts/4-coat/README.md: what the image is, its size and format, and its limits.

There are no unmet visual requirements. The preview only shows my two layers; the finished fren will depend on the other four agents' picks. ffprobe couldn't start on this machine, so I checked the image size and format with file instead.

Selected Background 11, Wireframe Red for its vivid grid and contrast with the fren. Saved the 672 × 672 PNG at fren.png and the pick at pick.json. The README records the PNG format, dimensions, and that no visual requirements are unmet. Verified the image properties and JSON syntax.

Completed the character/face pick:

• pick.json: Mumu (1) + Scientist (11)
• fren.png: valid 672×672 PNG, combo 45
• README.md: records dimensions, format, review, and requirements status

Created the Mumu Hat and Flask pick and saved the rendered fren.

• pick.json
• fren.png
• README.md records the 672 × 672 PNG format and that no visual requirements appeared unmet.

I checked the PNG dimensions and signature, parsed the pick JSON, and inspected the rendered image.
