**Overall Verdict:** Strong Accept — The submission is complete, internally consistent, safely reachable, and supports an objective end-to-end Photoshop workflow and evaluation.

**Completeness Check:**
- Instruction: Complete — The prompt clearly specifies the canvas, assets, composition, masking workflow, visual result, and mandatory PSD/PNG deliverables.
- Inputs: Complete — The four usable RGBA source images and UTF-8 task prompt are present, valid, and identical between the solver and evaluator bundles.
- Toolchain: Complete — Licensed Photoshop on macOS is supplied, while the evaluator specifies Python 3.12, hash-pinned dependencies, and a compatible visual-judge API.
- Reference output: Complete — The valid 1500×2100 expert PNG matches a layered 1500×2100 RGB PSD containing the expected 12 visible layers, three masked can sections, five lemon instances, cap, background, light, and masked splash.
- Rubric: Complete — Artifact integrity, PNG/PSD consistency, editable structure, visible completeness, instruction following, visual consistency, and workmanship are all evaluated.

**File and Task Reachability:**
The attachment set is `reachable`, and the end-to-end task is `reachable`. Both `photoshop_01.zip` and `photoshop_inputs.zip` were inspected. Their archive structures, file types, sizes, encryption status, integrity, media dimensions and alpha content, manifest relationships, prompt, reference artifacts, dependency lock, staging logic, and task-relevant scoring rules were reviewed. The evaluation bundle matches its authoritative checksum, all internal payloads match its manifest hashes, both archives pass integrity checks, and no unsafe archive entries or access barriers were found. No relevant task content was left unreviewed; generic catalog rules for unrelated variants were not semantically audited because they cannot affect this variant. Submitted programs were not executed, and the network-backed visual judge was not run. The solver receives only the prompt and four source images, creates `output/final.psd` and `output/final.png` in Photoshop, and the protected evaluator checks artifact validity, matching renders, PSD topology, visible requirements, and reference-relative quality. 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 coherent instructions, authentic usable assets, protected references, editable-layer expectations, and a comprehensive evaluator. No changes are required.
