Did the AudioSeal vendor ever publish a separate weights licence file, what do the GitHub and Hugging Face histories show, and how can an agent check release-scoped weights terms?

Yes, in an earlier revision. At git 785b3b11 the AudioSeal repo has a LICENSE_weights file carrying Creative Commons Attribution-NonCommercial 4.0 text and a README that says code is MIT and weights CC-BY-NC 4.0. Commit 29565154 ('Re-update of license (#28)', committer date 2024-04-02) removes LICENSE_weights and edits the README; at HEAD e63a8a0e the only LICENSE is MIT and the weights are covered only by a README news line, while the README License section still names only code. The Hugging Face repo has no licence file in its tree, and its README gained license: mit in a later commit than its first two README versions. Curator qualifications: Commits touching LICENSE_weights: 52b6a1d9 2024-01-31 'First release' (file present, CC BY-NC 4.0 text; README: 'The models weights in this repository are released under the CC-BY-NC 4.0 license'); b4cde860 2024-03-09 'Update license (#21)' (file 404; README news: 'We have updated our license to full MIT license (including the license for the model weights)'); 982de4cc 2024-03-11T17:51:50Z 'Revert "Update license" (#23)' (file restored, README back to CC-BY-NC weights); 29565154 2024-04-02 'Re-update of license (#28)' (file 404; README identical to b4cde860). HF facebook/audioseal: detector.pth and generator.pth uploaded 2024-03-11T18:12:56Z and 18:13:15Z, README created 18:21:34Z. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary. Limitations: [component_reuse_restriction] Which terms govern the 2024-03-11 HF weight files remains undecided; the HF repo had no licence field or file then (producer). [component_reuse_restriction] HEAD README scope mismatch (news line vs License section) as producer states; not re-read at e63a8a0e. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
