A commercial HFSS license is an executor environment prerequisite.\n- Reference output: Complete — The CSV and tuned AEDT project are coherent. The CSV contains 101 numeric records from 2.00 through 3.00 GHz at exactly 0.01 GHz intervals, reaches −46.77 dB at 2.45 GHz, and remains below −6 dB throughout 2.40–2.50 GHz.\n- Rubric: Complete — The pass threshold, target frequency, bonus band, CSV resolution, project validity check, and secondary design comparison are objectively specified.\n\n**File and Task Reachability:**\nThe attachment set is `reachable`; the end-to-end task is `conditionally_reachable` pending clarification of the intended HFSS solution formulation. `RectInset-10G-template-design.aedt`, `tuned_S11.csv`, and `RectInset_2p4GHz_ALE_output.aedt` were all inspected. Both AEDT files match their manifested sizes, identify themselves as unencrypted Electronics Desktop 2024 R2 text projects, have balanced nested project sections, empty script sections, and no external-file dependencies. The template contains the expected parameterized patch geometry but uses Duroid with a driven-terminal setup. The tuned reference changes the substrate to FR4, retunes all nine parameters, sets a 2.4 GHz adaptive solution, and provides sweeps covering the target region. Embedded preview thumbnails were not visually decoded, and the projects could not be opened, validated, or re-solved because HFSS was unavailable in the review environment; this is a reviewer-tooling limitation rather than evidence of file failure.\n\nThe completion path is otherwise direct: open the template in licensed HFSS, apply the intended substrate and parameter changes, update the adaptive frequency and sweep, solve, validate the design, and export the return-loss trace for numerical grading. Reference artifacts are appropriately separated from the solver input. 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.\n\n**Special Screening:**\nNone\n\n**Recommended Changes:**\nThe submission provides a usable model, a strong numerical reference, and an objective grading path. Clarify whether solvers should retain driven-terminal operation and export `dB(St11)`, as the reference does, or convert to driven-modal operation and export modal `S11`. Also correct the starting-state description to identify the supplied Duroid substrate and explicitly require changing it to FR4. Align the reference CSV filename with the required `RectInset_tuned_S11.csv` name to remove a minor packaging inconsistency.","reviewed_at":"2026-08-15T00:01:13.136635Z"},"claim":null}
