Emma Thorpe	d7a1930650	refactor(home): move personal data out of the shared home modules ... The dockerpi ssh host shortcut (home/shell.nix) and the gammastep night-light coordinates (home/sway.nix) were hardcoded in shared modules, so every host inherited them. Move both into a per-user module (users/lyrathorpe/home.nix) imported on Lyra's hosts only, not the work box; the gammastep block is Linux-guarded so Darwin skips it. No build change on existing hosts: the generated configs are byte-identical (verified by drvPath), the data is simply no longer in shared modules.	2026-06-29 13:02:34 +01:00
Emma Thorpe	f7ae46f462	docs: simplify code comments, keep the detail in the README ... The registry / multi-user / portable-home rationale lives in the README (Users, Hosts, Portable home); the corresponding code comments are reduced to one-liners that point there. No functional change (host derivations are unchanged).	2026-06-29 12:41:16 +01:00
Emma Thorpe	ea3e75e0af	docs: update READMEs and .gitignore for the restructured layout ... Point all path references at the new users/, home/, modules/, hosts/, lib/ locations, and document the user registry, the multi-user host model, and the portable homeConfigurations / homeModules outputs.	2026-06-29 12:27:52 +01:00
Emma Thorpe	10cc6cceed	refactor(flake): add user registry and multi-user host support ... Separate user identity (data) from the reusable modules, and let a host declare any number of users instead of exactly one. - users/registry.nix: per-user identity (name, email, groups, authorized and signing keys) as the single source of identity; no user data is hardcoded in the modules. - mkHost takes a `users` set keyed by username; per-user identity is injected into each home config via the `identity` module arg (extraSpecialArgs is per-host, so it cannot carry per-user data). - modules/users.nix builds accounts from the registry; modules/ssh.nix no longer defines authorized keys (the registry owns them); home/git.nix and home/desktop.nix read `identity`; users/emmathorpe/work.nix drops its now-redundant git identity override. - Restructure the tree: users/, home/, modules/, hosts/, lib/ replace the former lyrathorpe/ and system/ layout. - Add standalone homeConfigurations (the portable subset: shell, git, editor, claude) and an exported homeModules output for use on machines not managed by this flake, or as an input to other flakes. Behaviour-preserving for existing hosts: lyrathorpe-mbp and emmathorpe-edaas evaluate to identical derivations; lyrathorpe-t400, lyrathorpe-macpro31 and lyrathorpe-rpi5 differ only by de-duplicating a repeated authorized_keys entry. Fixes the SSH authorized-key leak (one user's key was applied to every account), the hardcoded default git identity, and the hardcoded EDaaS linger setting.	2026-06-29 12:27:52 +01:00
