with the new lazy-tree feature, the source tree isn't realised in the store at eval time. instead we get a virtual store path. that differs on every evaluation: ```bash $ nix eval --raw '.#apps.aarch64-darwin.genflake.program' /nix/store/bmwj8dj3vgrdsmm627vjdhl3aq06141c-source/genflake $ nix eval --raw '.#apps.aarch64-darwin.genflake.program' /nix/store/l38p4cvnczv37vd3d7hv296j2n1h8cfx-source/genflake ``` nix run then exec()s a path that was never materialised: error: unable to execute '/nix/store/.../genflake': No such file or directory instead, if we interpolate the self input, this forces realisation and gives a valid path, even under lazy-tree. This also keeps the string type that jorsn#6 needed, so nix flake check --all-systems still passes.

toPath ./genflake coerces a subpath of the flake source.
