CA-derivation paths will not be downloaded

[gador]

When uploading paths which have been build with contentAddressedByDefault = true from my config, the path will get uploaded, but not used when built:

nix build .\#nixosConfigurations.hel.pkgs.zsh # "hel" is my config
/nix/store/1d2fkbjv4z1sz4winic225yaqaqsjy01-zsh-5.9
nix path-info --sigs ./result

lzpyig9MIU1edDth1D0mfpuGHbAg==
nix-store --delete /nix/store/1d2fkbjv4z1sz4winic225yaqaqsjy01-zsh-5.9
nix build .\#nixosConfigurations.hel.pkgs.zsh # builds it all over again

My logs from the upload script:

Is there any setting I need to do when dealing with ca-derivations in combination with attic?

Currently the server doesn't store or expose the CA realizations (realisations/*.doi). There will be work required on the client and server to support this.

Ok, thanks, I feared as much 😆
