workspace-app-composition

How a workspace-backed app under `apps/*` is composed: the isomorphic doc factory (`create<App>`), the environment factories (`open<App>Browser` / `open<App>Extension` / tauri) with the one boot call (`connect(toConnection(auth, nodeId))`, ADR-0088/ADR-0094), the `#platform/*` build-time platform DI for multi-platform (Tauri) apps, the workspace singleton, the sign-in migration wiring, daemon/script placement under per-project `workspaces/<app>/`, and the file layout itself. Use when creating a new app, naming or placing the iso/browser/extension factory, wiring `#platform/*` subpath imports for a Tauri seam, placing the workspace singleton, wiring the first-sign-in migration, registering daemon/script bindings, or gating first paint on local storage hydration (load gate vs WorkspaceGate).
