//! v3.17 c1 — dogfood usecase: menu navigation (drawer in/out × 4 destinations).
//!
//! Port reference: `insight/tools/maestro/flows/main/menu-navigation.yaml`
//! & `insight/tools/maestro/subflows/open-menu.yaml`. Drives 4 round-trip
//! drawer navigations:
//!
//! 1. open-menu → Dashboard → btn-back
//! 2. open-menu → Manage Users → btn-back
//! 3. open-menu → Add Device → screen-add-device confirmed → btn-back
//! 4. open-menu → Manage Devices → "Manage Devices" header visible
//!
//! # Why this dogfood
//!
//! Exercises drawer-pattern navigation, a workhorse interaction in the
//! insight RN bundle. `open-menu` subflow itself is a repeat-until pattern
//! (tap "Open menu" until "Dashboard" visible) — first-証 the SDK can
//! express maestro's `repeat: while: notVisible:` idiom via a bounded
//! Rust loop. Also exercises `btn-back` id-selector return pattern and
//! `screen-add-device` route-key id assertion.
//!
//! # Reversibility
//!
//! Pure read — all 4 destinations are settings-side screens, no mutation
//! commits during this flow. `btn-back` returns to drawer-closed state;
//! final step (Manage Devices) leaves user on that screen — next dogfood
//! run starts with `reset_to_home` regardless, so no cross-test leakage.
//!
//! # Capability gap surfaced
//!
//! None planned. open-menu repeat-loop is bounded to 5 iterations
//! (maestro `repeat` is unbounded — if drawer trigger is wholly broken,
//! Rust loop fails fast at iteration 6 with clear wait_for error rather
//! than spinning forever).
