# Refreshes _data/conferences.yml from the ccfddl/ccf-deadlines dataset and
# opens a pull request with the proposed changes for human review. It never
# pushes to a deploy branch directly — a maintainer reviews and merges.

            Automated refresh of `_data/conferences.yml` from the
            [ccfddl/ccf-deadlines](https://github.com/ccfddl/ccf-deadlines) dataset.

            Only entries with a `ccfddl:` key are touched (ICASSP, Interspeech,
            SLT, ICML, ICLR, NeurIPS); identity/curation fields
            (`name`, `acronym`) are preserved. Manually-maintained
            entries such as ARR are left untouched.

            **Please verify the proposed dates against each conference's official
            site before merging** — the upstream dataset is community-maintained
            and can be incomplete or out of date. If there is nothing to update,
            no PR is created.
