These per-version observations remain visible, but this version does not contribute to aggregate pass rates.

The task

Write /app/dut.sv defining TopModule with ports clk, rst, wri, wrdata[31:0], wrlasti, wrreadyo, mtvalido, mtdatao[31:0], mtlasto, and mtreadyi. rst is synchronous active high and clears the FIFO and all outputs. The block buffers 32-bit write beats into a depth-8 FIFO and emits them in order on an AXI4-Stream master interface. Assert wrreadyo when the FIFO is not full. On a rising edge with wri=1 and wrreadyo=1, pus…

Results by model and effort

This exact task version only. Every rate is passes / valid runs with a Wilson 95% interval; n≤2 remains counts only. Macro aggregation does not apply within a single task. Baselines are summarized in the quality gates, not ranked. A passed no-op resistance check means that doing nothing did not solve the task.

Every recorded run

11 recorded trials, including controls. Diagnostic labels do not replace verifier reward. Labels and quality checks are source declarations, not independently attested here. Internal evidence remains private; a missing public URL is shown explicitly. Records with invalid or absent rewards are not scored.
