The task

A bridge shares one read-only memory port between requesters A and B, keeping neither starved. Ports: clk, rst, areqi, aaddri (8), aacko, adatao (16), breqi, baddri (8), backo, bdatao (16), mreqo, maddro (8), mdatai (16). rst is synchronous active high, clearing all state and outputs to 0. All outputs are registered. A requester holds req and addr stable through the cycle after its ack. The bridge samples on the idl…

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

10 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.
