// Directory discovery API — security + contract regression coverage.

// These tests run under the jest + docker harness (redis + the test seed).
// They lock in the two fixes from the @simpleworkjs/directory-schema release:
//   1. /api/discovery/* returns the { results } envelope (not a bare array —
//      the drift that made jump-host's `data.results || []` collapse to []).
//   2. No response path leaks secret metadata (e.g. an OAuth client's
//      client_secret_hash), regardless of caller.
//
// The core assertions hold for any authenticated caller. The admin-projection
// assertion (fullMetadata for directory admins) additionally requires the `test`
// seed user to be a member of app_sso_directory_admin — see setup.js.
