/**
 * Composition-root integration test — the "tests pass, prod breaks" cure.
 *
 * WHY: all three P7 dogfood bugs (wizard mount missing providers; coord
 * client never attached; people deduped by id only) shipped to prod with the
 * full unit suite green, because unit tests inject their own mocks instead
 * of exercising the real app.js wiring. This suite boots the REAL createApp()
 * on an ephemeral port and drives HTTP through the real mount table — the
 * exact wiring that runs in production — for the routes that historically
 * broke: /network/wizard, /security/shield, /catalog/:id, /deploys.
 *
 * Uses DATA_DIR to point the app at a throwaway data dir; no prod files are
 * touched.
