Peritheos distribution licensing scope

LicenseRef-Peritheos-Distribution identifies the component-specific terms of
the Python distribution. It is a summary reference, not a new license or a
grant over third-party material.

Peritheos implementation code and contributor-authored documentation use the
MIT (Expat) license in LICENSE. References to scientific articles in code do
not change that code license. Explicit additional grants remain available.

Scientific data and retained third-party artifacts have separate terms.
Consult peritheos/data/LICENSING.md, the included dataset-specific notices,
and each resource's source/rights metadata. Some source datasets are CC BY
4.0 or CC0; other source terms are unspecified or restricted. A contributor
CC0 dedication covers only the contributor-held rights stated in its notice.
It does not grant rights held by the authors or publishers of source material.

MIT, CC BY 4.0 and CC0 texts are included with this distribution. Their presence
does not apply any of these licenses to files outside their stated scope.
Unknown source terms remain unknown; this reference does not establish that
every bundled resource meets a downstream distributor's licensing policy.
