``` The template is not valid. ... hashFiles('...') failed. Fail to hash files under directory '...' ``` Recently CI started to fail sporadically (such as in https://github.com/tectonic-typesetting/tectonic/actions/runs/19619400736/job/56176947266). This is not our problem - it is due to a bug from the macos runner images that is recently pushed: https://github.com/actions/runner-images/issues/13341#issuecomment-3568650155. This issue simply reports the finding so that we can ignore this failure for the moment and avoid unnecessary debugging.
