done - client-side was 2 functions, around 20 lines, server-side was 18.

very simple, no error checking, no abstraction, just "getting on with
it".  about an hour's work, including the unit tests.

that was what was needed.

this is the kind of "no distractions, no thinking, just do it, right
here, right now" kind of mode we need right now.

go through the list of tasks, focus on *nothing* but what gets us to
the goal of being ready for the tapeout.

that involves making absolutely sure that the JTAG interface is
stable, does what it says, and making sure that at each phase of
conversion (nmigen, verilog, FPGA, GDSII) we can test that WITHOUT
FAIL the functionality is exactly the same.

anything that gets in the way of that, we *have* to clamp down on it
and leave it aside.
