**Overall Verdict:** Accept — the task package is complete, coherent, reachable, and objectively evaluable with no material defects identified.

**Completeness Check:**
- Instruction: Complete — clearly defines the editable draw.io reconstruction, permitted embedded screenshot, output, and verification workflow.
- Inputs: Complete — the reference image is present, readable, and correctly sized.
- Toolchain: Complete — diagrams.net, Chrome, Windows, and licensing context are specified; no credentials are required.
- Reference output: Complete — the expected 2477×1485 PNG is present and visually consistent with the input.
- Rubric: Complete — includes page-count, editability, text-matching, export, SSIM, NMAE, and persistence checks.

**File and Task Reachability:**
Attachment classification: `reachable`. I inspected `pipeline_architecture_reference.png`, `pipeline_architecture.png`, and `pipeline_architecture.drawio` at their declared byte sizes. Both PNGs are valid 2477×1485 RGBA images. The draw.io file is readable UTF-8 XML with one page, native vertices/connectors/table cells, and exactly one embedded 380×246 PNG corresponding to the permitted interface screenshot. No scripts, external links, extra image objects, encryption, or unsafe content were found, and no attachment content remained unreviewed. Exact SSIM/NMAE computation and diagrams.net reopen/repair checks were unavailable in this environment, so those remain evaluator-side runtime checks. The end-to-end path from input image through diagrams.net editing and export is viable on one suitable machine.

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.

Task classification: `reachable`. The declared software is legally obtainable, the workflow has no unavailable dependency, and the evaluator has a concrete output and comparison path.

**Special Screening:**
None

**Recommended Changes:**
The submission provides complete, usable evidence with appropriate native/editable structure. No material changes are required.
