* chore: write the site name as evomedia.net, lowercase The name is a domain and is written as one. Script headers, the README, CHANGELOG and elevator pitch, their .txt twins, and the site page -- matching the same sweep in the private evo.scripts so the mirror does not drift. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore: refresh CHECKSUMS.txt for the lowercase sweep Every script's header changed, so every hash did. The repo's own Checksums test caught it -- which is what it is for. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com>

"""Render this repo's markdown to plain-text twins with the markup removed.
|
|
|
|
The .txt files exist for terminals, pagers and anywhere markdown doesn't
|
|
render. They are generated - never edit one by hand:
|
|
|
|
python scripts/plaintext_twins.py # rewrite every .txt twin
|
|
python scripts/plaintext_twins.py --check # exit 1 if any is out of sync
|
|
|
|
tests/PlainTextTwins.Tests.ps1 runs --check, so a markdown edit that forgets
|
|
to regenerate fails the suite instead of shipping a twin that disagrees with
|
|
the file it mirrors.
|
|
|
|
Was readme_txt.py, which did README only. CHANGELOG.txt was kept by hand and
|
|
drifted the moment CHANGELOG.md was reorganised - and its docstring claimed a
|
|
--check the suite never actually ran. Both are fixed here: one renderer, every
|
|
pair, and a test that invokes it.
