This product includes software developed by the Open Source Security
Foundation and the Sigstore project (https://www.sigstore.dev/), used only
as optional external tooling for release-artifact transparency logging.
No Sigstore code is vendored or redistributed in this repository.

Earlier v0.2.1 draft releases shipped a third-party timestamp proof
(dist/uibc-core-0.2.1.zip.ots and timestamps/uibc-core-0.2.1.zip.ots),
generated with the OpenTimestamps client (https://opentimestamps.org/), which
is licensed under the GNU Lesser General Public License v3.0; the proof file,
not the client, is what was distributed. Re-verification on 2026-09-26 found
that this proof does not constitute a valid OpenTimestamps time anchor, so it
is retained for audit only and must not be cited as evidence of existence or
priority.

Third-party source documents referenced in research notes are not
redistributed in this repository.
