 - `bun.lock` is the source of truth for JS dependencies.
 - `bun.nix` is generated from `bun.lock` with `bun run update:bun-nix`.
 - `flake.nix` imports the `bun2nix` overlay and exposes `packages.<system>.default` plus `nixosModules.default`.
-- `nix/package.nix` uses `bun2nix.fetchBunDeps` with `bun.nix`, runs `bun run build`, and installs the bundled `server.js` plus frontend assets as the `leo-ed` executable.
+- `nix/package.nix` uses `bun2nix.fetchBunDeps` with `bun.nix`, runs `bun run build`, and installs the bundled `server.js` plus frontend assets as the `kotsukotsu` executable.
 
 Whenever dependencies change, update both `bun.lock` and `bun.nix` in the same commit. CI checks that `bun.nix` matches the lockfile by regenerating it and failing on diff.
 
 ## Server and Deployment Model
-This repo is the application source, not the full server configuration. Production is intended to be managed from a separate NixOS infra repo that imports this flake and sets `services.leo-ed.package = inputs.leo-ed.packages.${pkgs.system}.default;`. The included module in `nix/module.nix` defines the systemd service, runtime env (`APP_ORIGIN`, `PORT`, `SQLITE_PATH`, `SESSION_COOKIE_SECURE`), and persistent state directory.
+This repo is the application source, not the full server configuration. Production is intended to be managed from a separate NixOS infra repo that imports this flake and sets `services.kotsukotsu.package = inputs.kotsukotsu.packages.${pkgs.system}.default;`. The included module in `nix/module.nix` defines the systemd service, runtime env (`APP_ORIGIN`, `PORT`, `SQLITE_PATH`, `SESSION_COOKIE_SECURE`), and persistent state directory.
 
 `server/config.ts` exists so production behavior is explicit: WebAuthn origin/RP ID, SQLite path, bind host, and secure cookies should come from NixOS service configuration, not reverse-proxy accident.
