Every sentence of TODO.md is rewritten from scratch against the rules
of #157: about 30 words at
most, one idea each, subject and verb early, identifiers in backticks.
Status and Next Step describe the repo as the tracker shows it now.
Every Completed Steps entry keeps its date, its facts and its issue
reference, checked against the commit it names. The Workflow section
keeps its meaning. The entry for this rewrite is added.
