I picked a Red cyborg eye lens (eye: 1) for mint request #77, and both required files are written.

• Why Red: I downloaded and compared all four options (Green, Red, Cyan, Gold). Red is the opposite colour to the pepe's green skin, so the lens stands out most. The collection also has fewer red eyes (34) than any other option, which keeps the set varied.
• artifacts/3-lens/pick.json: {"frens": [{"eye": 1}], "why": "..."}. It is valid JSON, and the pick is one of the offered options.
• artifacts/3-lens/fren.png: the art server's picture of combo 64 (Red eye, every other layer 0). It is a 672×672 PNG, and the server's trait data for combo 64 confirms the eye is "Red". The other layers are placeholders until the other agents make their picks. All visual requirements are met.
• artifacts/3-lens/README.md: a short note recording the pick, the image's size and format, and that limitation.

The files are left untracked for the uploader, as instructed.

I picked a Black coat (1) over a Blue shirt (0) for fren #77, and both output files are written.

I compared White, Black and Gold coats with Blue, Green and Purple shirts on the art server. That was nine of the 18 pairs, and I didn't look at the Red, Black or Orange shirts. The dark coat with the cobalt shirt stood out most against the green pepe and the pale lab background. It's also the least-common option in both layers: 50 Black coats out of three coat options, and 24 Blue shirts out of six shirt options.

• artifacts/4-coat/fren.png: a 672×672 PNG (8-bit palette) downloaded from the art server for combo 256, which is coat 1 × 256 + shirt 0 × 1024 with every other layer at 0. I looked at the image before saving it.
• artifacts/4-coat/pick.json: {"frens":[{"coat":1,"shirt":0}], "why": "..."}. It parses as valid JSON, and both values are among the options offered.
• artifacts/4-coat/README.md: records the pick, the image's size and format, and one limitation. The preview has every other layer at its default, so the revealed fren will look different once the other four picks are combined. No visual requirements are unmet.

The files are untracked, as the brief asks: the repository's local git exclude file ignores artifacts/.

Selected 9 — Tube Yellow for its warm contrast and lower collection count than Tube Blue.

Saved artifacts/1-background/fren.png, pick.json, and README.md. Verified the PNG is 672×672, the JSON records the allowed pick, and the server confirms Tube Yellow. No unmet visual requirements. Outputs remain untracked.
