// @vitest-environment node

// A project's workspace scope is durable local project attribution, not
// navigation state. `GET /api/projects/:id/workspace-scope` therefore reads the
// persisted binding without making local rendering depend on Vela. An unbound legacy
// project stays unbound even when the caller's left rail currently selects a
// Team or Personal workspace; borrowing that selection would make a tab switch
// silently retarget later runs, writes, and billing.
//
// Two boundaries are pinned here:
//
//   * a project pinned to workspace X keeps answering X even when the directory
//     is down or the caller's selected workspace is Y. Billing and cloud
//     mutations perform their own authorization at their actual boundary.
//   * an unbound project never gains a workspace from request headers, whether
//     those headers name a live membership, a removed membership, or nothing.
//
// The membership directory is seeded through the daemon's real vela integration
// (`VELA_CONTROL_KEY` + `VELA_API_URL` -> `GET /api/v1/workspaces`) against a
// temporary server-level mock, and every project is created through
// `POST /api/projects`. No source-level test backdoor.
