ah - i found the problem:
Requirement already satisfied: power-instruction-analyzer==0.1.0 from
in /home/lkcl/.local/lib/python3.7/site-packages (0.1.0)

updates need a version increment.  to keep the same version you'd need
to provide full instructions on how to bypass the use of pip3 as a
build/install dependency.  instructions "hunt down pre-installed
versions and rm -rf them" wouldn't qualify :)  there may be a
"--force" option to pip3.  simplest thing instead: always remember to
increment the version number (0.1.1)

yes, haven't had time, as it will require its own pipeline or we add
another reg RC to MUL.  reluctant to do that

$ grep madd isatables/*

hmm shouldn't be
