Please describe the problem.
Finally got to try the neat p2p (inspired by trr379 use-case raised in matrix), ultimately with the hope to connect to datalad-fuse. Wanted to test range request support (since was reported to be lacking by claude on a forgejo+aneksjo instance) and thus thought to try on the most recent version locally. Unfortunately
whenever p2phttp worked fine (for a full file) request on 10.20251029

What steps will reproduce the problem?
this was on a local clone of https://datasets.datalad.org/dbic/QA/.git with sourcedata/sub-qa64/ses-20240715/func/sub-qa64_ses-20240715_acq-faX77_bold.dicom.tgz content
What version of git-annex are you using? On what operating system?
10.20260316+git1-g768707adf4-1~ndall+1 - not ok; 10.20251029 - not ok.
FWIW -- https://github.com/datalad/git-annex testing was not happy for awhile but I think it was due to some change in behavior affecting RIA archives (I did not have yet chance to troubleshoot manually to report) , thus unrelated here.
