M10: the funnel and the PEP 545 milestone

[tamnd]

The funnel and the PEP 545 milestone. Human work, plus deterministic tooling.

Checklist

• A person reads all of tier 1 against the English
• Entries unfuzzied one at a time as they are agreed. There is no bulk command and there should not be one
• Last-Translator updated per reviewed file
• Reviewed strings submitted through Transifex by the reviewer, under the Documentation Contribution Agreement
• ROADMAP.md rewritten off pydocvi report coverage. The current one says zero words are formally translated, over a repo holding a million words of machine output, and that gap is the thing to fix
• README states plainly what is machine output, what has been reviewed, and what PEP 545 actually requires
• pydocvi apply --branch 3.14 produces the 3.14 catalogs from the same memory, which is what makes the shared-memory claim real rather than asserted

Exit

bugs.po, tutorial/ and library/functions.po fully human-reviewed and submitted through Transifex. The coverage table is generated and true. No claim anywhere in either repository that machine output satisfies PEP 545.
