Does
$ nix-store --read-log /run/current-system/sw
say anything interesting?
$ nix-store -q -deriver /run/current-system/sw
will output a filename. Are there references to AgdaStdlib in that file?

Assumption II: I'm not sure exactly what you mean by "check under test_profile"
The directory at `nix-build --no-out-link "<nixpkgs>" -A AgdaStdlib` has a
share/agda directory, which I think is what you're looking for.
Assumption III: I have succeeded in installing other packages. (e.g. emacs)
With this syntax. There is an emacs folder in /run/current-system/sw/share/
putting "42" in that same place does result in an error.
Assumption IV: I'm not sure how this works. Where is all-packages.nix? I
switched to the unstable branch with nix-channel, but that should be a
user-level change, right? Not system-level.
Assumption V: nixos-rebuild switch changes what I have installed. That should
rule out that problem, no?
Thanks for the help. Any other things that could be going wrong?

There's also the one that tripped me up:
- Assumption: NixOS is mounting /boot properly, otherwise new system
generations won't take effect on boot but 'switch' will think
everything's applied.
