  ^ Warning: codespell identified likely spelling errors. Any false positives? Add them to the list of ignored words in test/lint/lint-spelling.ignore-words.txt

Note:

* homogenous is present in tinyformat, hence should be addressed upstream
* process' is correct only if there are plural processes
