 - Reusable Home Manager concerns are published as `flake.modules.homeManager.<name>`.
 - Hosts are aspects too. `orion`, `polaris`, and `zenith` are `nixos` aspects assembled from smaller aspects.
 - Host modules should use `config.meta.lib.mkHost` to define `meta.host`, base imports, hostname, and state version.
-- Per-user Home Manager composition should use `config.meta.lib.mkHostUser` so `meta.host` and `meta.user` stay available to Home Manager features.
+- Per-host user declarations should stay inline under `users.<name>` using canonical accounts from `meta.lib.accounts`, so host-local defaults stay close to the host and `mkHost` can wire `meta.host` and `meta.user` into Home Manager consistently.
 - Features may rely on the `meta` contract. Existing modules already read `config.meta.host`, `config.meta.user`, and `config.meta.lib`.
