The previous LICENSE contained only the short FSF boilerplate with "either version 3 of the License, or (at your option) any later version" — AGPL-3.0-or-later language that contradicted AGPL-3.0-only declared in README, pyproject.toml, and SPDX headers in every source file. Replace with the complete canonical AGPL-3.0 license text from the FSF. The SPDX-License-Identifier headers in source files remain the authoritative "only" declaration.
