Shields renders it from a static JSON file served here, so it stays current without anything running.

What this does not establish

A pass is not a proof of correctness. These checks say the design elaborates, infers no latches, synthesises and contains clocked logic. None of them compares it against a specification.
Generic yosys cells are not silicon area. Only the real ASIC flow settles whether a design fits its tiles.
No frequency is claimed. Counting flip-flops says a frequency is a meaningful question, not what the answer is.
Nothing here ran on hardware. These are simulation and synthesis results.
