'the SmartPlant 5-segment scheme' was the only product-name reference
left anywhere in the public tree (found by a full sanitization sweep:
paths, keys, domains, IPs, emails, ssh details, sibling-repo coupling
- everything else already clean). The scheme description stands on its
own without naming where it came from.
CHANGELOG.txt is the plain-text mirror the docs rule requires for any
touched .md - generated mechanically (headings underlined, markup
stripped, code blocks indented).
CHECKSUMS.txt is untouched: it covers .ps1/.cmd only.
