I think I have multibit-manipulation.py debugged and ready for review. Do you have any suggestions ? Does the module name really describe what it does ? Are the comments unclear or too long ?

All the parenthesis in the multi-bit functions are complicated, but they run measurably faster on a Raspberry Pi Pico as a single statement. No garbage collection of course ( especially in 264K ), but Python seems to optimize these constructions beyond just saving memory and reference scavenging. After working with them, I find them readable in a straightforward left-right manner. Kind of harking back to the bit buffers of yesteryear, except they implemented it with hardware.

I had a problem with Ruff on my client workstation. There were many validation it didn't check. Is there a TOML configuration file I can use to match my Ruff to yours ?
