Done. Hash verified, image inspected both visually and by decoding it.

Verdict: ACCEPT — artifacts/review.json

Authentication: downloaded to /tmp/cand_iu0567/ (outside the repo, not committed); sha256 matched the expected c423bca1…93253bbe exactly.

Measured evidence (independent zlib/PNG decode, no image library, so these are reproducible rather than eyeballed):

• True pixel art — 512×512 is an exact 16× upscale of 32×32, and 0 of 1024 logical cells contained more than one colour. Anti-aliasing, blur or gradients would all produce mixed blocks, so this is decisive.
• Palette fully legal — 9 colours, every one on the allowed list: background #0c1610, black outlines, steel, navy, bone, cobalt, phosphor, moss, rust.
• Background — solid #0c1610 with exactly 3 single-cell moss specks. No scenery.
• No text — no tEXt/iTXt/zTXt chunks, no glyphs, no watermark or border.
• One character, centred bust, shoulders occupying row 31 (the bottom edge).
• All five traits located by cell: riveted bot chassis with bolted ear panels; steel is the sole skin colour; single phosphor dot eyes at (11,15) and (20,15) in black sockets; outlined antenna with phosphor bulb at rows 1–6; navy jacket with cobalt lapel folds parted over a bone placket at rows 27–31.

No reject condition fired.

Where I used judgement rather than measurement — style 10 rests almost entirely on the decode. The other three axes are interpretive: I read the garment as a jacket from the parted lapels plus separate placket, and docked originality to 7 because the boxy-head/dot-eyes/antenna combination is the default bot vocabulary, lifted only by the ear lights, rust brow bar and open-jacket treatment.

Limits, flagged rather than papered over — rule 7 (cohesion with the wider set) is not verifiable from a single artifact; I judged it against the style rules as written. I also noticed the brief states both "615 Units" and "a 787 piece set"; I did not resolve that and it did not affect the verdict. Both are recorded as open questions for the requester.

artifacts/README.md holds the full evidence trail with facts, inferences, uncertainty and open questions kept separate. Both files are untracked (artifacts/ is excluded via .git/info/exclude) and nothing was committed or force-added, so the daemon uploads them itself.
