Downgrading (testing on local laptop) local git-annex all the way down (didn't try intermediates yet) to 6.20170101-1+deb9u2 helped - I can fetch data from that server.
My wild guess is that it all relates to the fact that remote git-annex-shell, being outdated, has no clue about `p2pstdio` command, and local new git-annex doesn't fall back anyhow to use some other way to transfer.

FWIW, here is what I see if I just try to invoke directly
[[!format sh \"\"\"
$> ssh bids@rolando.cns -T git-annex-shell 'p2pstdio' '/inbox/BIDS/dbic/QA' '--debug' 'ba8f2cea-f229-422c-82be-6580e5e07ed5' --uuid 6384a551-a41d-4290-b186-9258befede97
...
fatal: Run with no arguments or with -c cmd
git-annex-shell: git-shell failed
1 5358 ->1
\"\"\"]]
so - exit code is `1` (happen annex decides on exit code about availability of p2pstdio)

Hi Ilya_Shlyakhter, thanks for your answer.
I'm not sure about using different branches. What prevents other users from just checking out the branches, also the git-annex branch tracks the clear names of all remotes. Moreover, it's a scalability question. Assume the server has thousands (millions?) of files while the phone has only a few. Then it still would be \"bothered\" all the location tracking information of the server.
But one thing in the »local caching« tip raised my attention: \"git config remote.cache.annex-speculate-present true\"
The tip says: \"The annex-speculate-present setting is the essential part. It makes git-annex know that the cache repository may contain the content of any annexed file. So, when getting a file, git-annex will try the cache repository first.\"
Together with \"git config remote.cache.annex-pull false; git config remote.cache.annex-push false\" this could be pretty close to my \"local location tracking\" idea.
It further says: \"The cache repository will remain an empty git repository (except for the content of annexed files). This means that the same cache can be used with multiple different git-annex repositories, without intermingling their git data.\" Thus, there should be no »information leaks« between two repos that both use this cache.
A thing I would have to work around is that I should not do \"git annex --copy --to server --not --in server\". Or, at least before doing this I should always log into the server and do \"git-annex get\" first.
Thanks again for your suggestion. I will give this approach a try.

See also config settings remote.<name>.annex-readonly , remote.<name>.annex-push, remote.<name>.annex-pull etc.

If I understand correctly, git-annex-unused will by default cause old versions of files to be lost?
