**Overall Verdict:** Accept — The task is coherent, professionally scoped, and end-to-end reachable, with only reviewer-tooling uncertainty about the proprietary reference DWG’s model-space contents.

**Completeness Check:**
- Instruction: Complete — The editable CAD deliverable, required geometry, dimensions, labels, openings, and expected fidelity are clearly defined.
- Inputs: Complete — `input.png` is a valid 2382×1684 RGBA PNG with valid chunk checksums and no trailing data; its visible plan agrees with the written specification.
- Toolchain: Complete — AutoCAD or compatible CAD software is allowed, and the renderer’s Python and ODA File Converter dependencies are disclosed.
- Reference output: Unclear — `output.dwg` has the expected size and a valid AutoCAD 2013–2017 DWG signature, but its entities, layers, and rendered appearance could not be fully inspected without a compatible local DWG parser.
- Rubric: Complete — The objective visual criteria, scoring weights, major-error definition, renderability gate, and passing threshold are explicit.

**File and Task Reachability:**
The attachment set is **partially_reachable**, while the end-to-end task is **reachable**. All four files were inspected: `input.png`, `output.dwg`, `dwg_to_png.py`, and `requirements.txt`. Actual formats and byte counts match the manifest. The PNG was structurally validated and visually inspected; the renderer and dependency file were reviewed as text without execution. The unreviewed content is the DWG’s detailed entity, layer, and model-space inventory because no compatible non-executing DWG parser or renderer was available in the review environment. This is a reviewer-tooling limitation rather than evidence of a defective submission. The manifest correctly separates the PNG as solver-visible input from the DWG and rendering materials as reference/evaluator assets. A solver can reconstruct the plan in compatible CAD software and submit an editable DWG; an evaluator with the documented ODA and Python dependencies can render both DWGs and apply the supplied visual rubric. 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. No affirmative evidence supports a special-screening label. Public-source identifiability was not externally checked because external search is outside the authorized evidence boundary.

**Recommended Changes:**
The submission provides a coherent target, a valid editable-output contract, and an objective evaluation path. No contributor changes are required. Evaluation deployment should provision the already-documented ODA File Converter dependency before running the renderer.
