Hello,
when reviewing a pull request by Yaakov [1], I realized Python bundles [2] the reference blake2 implementation known as libb2 [3]. We already have that packaged in Fedora as libb2, licensed as CC0. The library itself has:
To the extent possible under law, the author(s) have dedicated all copyright and related and neighboring rights to this software to the public domain worldwide. This software is distributed without any warranty.
You should have received a copy of the CC0 Public Domain Dedication along with this software. If not, see http://creativecommons.org/publicdomain/zero/1.0/.
In the source files.
So this is "public domain" but it also mentions CC0 Public Domain Dedication explicitly. Is this LicenseRef-Fedora-Public-Domain or CC0-1.0? And if it is the latter, how do I deal with that?

I think it's LicenseRef-Fedora-Public-Domain.
First, it does not match any SPDX-known license text. Second, "CC0 Public Domain Dedication" probably refers to SPDX license CC-PDDC https://creativecommons.org/licenses/publicdomain/. Third, the http://creativecommons.org/publicdomain/zero/1.0/ link refers to CC0-1.0, a different license from CC-PDDC.
Last, recently I asked a similar case (a public domain dedication with a fallback to a license) https://gitlab.com/fedora/legal/fedora-license-data/-/issues/306#note_1530527250 and Richard Fontana concluded that these kind of texts fall into LicenseRef-Fedora-Public-Domain bucket.

In the case of blake2 though there is a copy of the CC0 text in the COPYING (previously named LICENSE) file in the repository.

I'd treat this as CC0-1.0 (I don't think that is altered by the form of license notice on individual source files). Presumably it's covered by the grandfathering exception https://gitlab.com/fedora/legal/fedora-license-data/-/blob/main/data/CC0-1.0...
