**Overall Verdict:** Strong Accept — The submission is complete, internally consistent, objectively evaluable, and fully reachable with appropriately separated solver and evaluator assets.

**Completeness Check:**
- Instruction: Complete — Clearly defines the 16 ordered inputs, one-character transcription requirement, `UNKNOWN` exception, exact output filename, and JSON structure.
- Inputs: Complete — `001.png` through `016.png` are readable isolated cursive Chinese glyphs with consistent filenames and no visible answer annotations.
- Toolchain: Complete — Python 3.9 or later and a PNG-compatible viewer are legally obtainable and sufficient on macOS.
- Reference output: Complete — `answers.json` parses successfully and uniquely maps all 16 filenames to single CJK Unicode characters. Its internal audit schema differs from the solver artifact but supports deterministic evaluation and agrees with the self-test evidence.
- Rubric: Complete — Exact filename and Unicode comparisons, malformed-output handling, per-image audit results, and count/percentage scoring are fully specified without an arbitrary pass threshold.

**File and Task Reachability:**
The attachment classification is `reachable`, and the end-to-end task classification is `reachable`. All manifest attachments were inspected: `001.png` through `016.png`, `answers.json`, and `evidence.png`; no content was left unreviewed. All 17 PNG files matched their declared byte counts and actual formats, decoded successfully, had valid container structure and checksums, and contained non-interlaced RGBA imagery. The task images range from 124–384 pixels wide and 174–420 pixels high; the self-test image is 514 × 512 pixels. The 910-byte UTF-8 JSON reference is parseable and structurally complete. The self-test image documents 0/16 accuracy and displays expected labels consistent with the reference; both answer-bearing attachments are categorized separately from solver-visible inputs. A solver can inspect the 16 images, produce `predictions.json`, validate its exact key set, and be evaluated through 16 auditable exact-match comparisons. No material tooling limitation was encountered. License keys, accounts, tokens, and other credentials are not required from the contributor. Confidential, proprietary, or internal material may be evaluated as submitted evidence without requiring additional disclosure.

**Special Screening:**
None

**Recommended Changes:**
The submission already provides usable inputs, coherent instructions, complete ground truth, and an objective scoring path. No contributor changes are required. Preserve evaluator-only access controls for `answers.json` and `evidence.png`, since both contain the protected answers.
