A physical FPGA, STM32 board, cable, and LEDs are not required. Reproducible Yosys synthesis, Icarus Verilog simulation, and host-compiled mock-GPIO tests replace physical-board observation.\n\nInstructions & Rules: Complete the dual_port_ram SystemVerilog module using the required six-port interface. Reads and writes occur on the rising clock edge. Memory changes only when wren is high. A simultaneous read and write to the same address must use READ_FIRST behavior, returning the old stored value on q. Complete the portable C GPIO API without directly accessing hardware registers. Generate the exact 17-word write sequence and 16-word read sequence defined in the supplied contracts. Preserve all required paths and function signatures, remove incomplete-work markers, and place the four required deliverables under base/output/. The report must contain a Mermaid flowchart, reproducible experimental results, discussion, and lessons or recommendations. Do not claim that a physical FPGA or STM32 board was tested.\n\nRequired Output:\n\nbase/output/rtl/dual_port_ram.sv\n\nbase/output/firmware/dual_port_gpio.h\n\nbase/output/firmware/dual_port_gpio.c\n\nbase/output/REPORT.md\n\nEvaluation: The submission receives a score of 1.0 only when every hard gate passes. The evaluator independently runs Yosys synthesis, Icarus Verilog simulation, strict C11 compilation, mock-GPIO sequence tests, and report validation. Screenshots, copied logs, or self-authored pass statements are not accepted as substitutes for executable evidence.","software_licensing":"In-house/Proprietary","evaluation_criteria":null,"verification_method":"Success is verified using evaluator-controlled synthesis, compilation, simulation, and report checks.

Infrastructure failures are correctly separated from submission failures.\n\n**File and Task Reachability:**\nAttachment classification: `reachable`. Task classification: `reachable`.\n\nBoth ZIP attachments were inspected. Their downloaded sizes match the manifest: 16,441 bytes for the 16-member input packet and 1,728,030 bytes for the 25-member reference/evaluation packet. Both are readable, unencrypted ZIP containers containing regular files with safe relative names, modest expansion, and no traversal paths, links, device entries, or decompression errors. All members match the sizes and SHA-256 values in their package-provided integrity inventories.\n\nThe inspected input members were `ALE_UPLOAD_GUIDE.md`, `README.md`, `input_manifest.json`, `optional_extension.md`, `output_contract.json`, `package_integrity.json`, `task_card.json`, `task_description.md`, all four files under `specs/`, and all four starter-project files.\n\nThe inspected reference members were both adapter files; all evaluator files; all four known-good fixture files; `README.md`, `package_integrity.json`, `reference_evidence_audit.md`, `requirements.txt`, `source_content_summary.md`, `strict_comparison_rules.md`, and `tests/test_evaluator.py`; plus `source_provenance.json`, the five-page `original_experiment.pdf`, and all five rendered page PNGs. The PDF is unencrypted, has no JavaScript or forms, and its extracted text and visible pages support the supplied source summary. The PNGs are readable 1191×1684 RGB page renders. No attachment content was left unreviewed.\n\nThe end-to-end path is clear: complete the four source/report outputs, synthesize the HDL with Yosys, compile and simulate it against the evaluator-controlled Icarus testbench, compile the C API under strict C11 flags, execute the mock-GPIO harness, and validate the report. Submitted programs were not executed during this safety-constrained review, and fresh runtime validation was unavailable in the review environment; this is a reviewer-tooling limitation rather than a submission defect.\n\nLicense 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. The source handout provides affirmative professional provenance, and the task is an adaptation rather than an AI-fabricated core or synthetic defect fixture. No external public-identifiability search was permitted, so public-benchmark assessment is limited to the submitted evidence, which contains no affirmative indication of a public benchmark.\n\n**Recommended Changes:**\nThe task validly replaces unavailable physical hardware with reproducible executable checks and resolves the source handout’s width and collision ambiguities explicitly. No material changes are required. As optional consistency cleanup, align references to “exactly four files” with the normative contract’s allowance for additional unscored regular files.","reviewed_at":"2026-08-29T16:38:33.878764Z"},"claim":{"id":"41a4147b-9aae-4a6c-9f89-063dc544c333","submission_id":"829b9e87-5d89-4e56-b8e1-0d4baad04ec3","submission_revision_id":"06276114-13a6-4517-bbed-45623bc40965","builder":"builder-01","status":"active","claimed_at":"2026-10-15T15:13:43.281165Z","delivered_at":null,"ended_at":null,"delivery_note":null,"end_reason":null}},"revision_is_current":true}
