//! v3.9 c2 — dogfood usecase: alerts events (spatial+index 第三次 distinct surface).
//!
//! Port reference: `insight/tools/maestro/flows/main/alerts-events.yaml`.
//! Drives the Alerts → Events sub-tab, taps the first event row that
//! sits **below the People|Vehicle|Weapon section header** at index 0,
//! then exits back via the in-app btn-back.
//!
//! # Why this dogfood
//!
//! Third distinct surface for the `Selector::Text + Modifiers { below
//! + nth }` compound:
//!
//! - v3.7 c2 search-person: below "Today|Yesterday" recent-people list
//! - v3.8 c2 search-filter: below "Device" filter modal device list
//! - v3.9 c2 alerts-events: below "People|Vehicle|Weapon" event list
//!
//! Each surface uses a different ancestor + virtualisation strategy,
//! so the third pass tightens confidence that the resolver's spatial
//! + nth pipeline is composition-stable across the RN-rendered tree.
//!
//! Also exercises:
//!
//! - `id("btn-back")` in-app back navigation (same path as v3.4
//!   baseline `flow_manage_users`'s exit step)
//! - regex `wait_for` covering both detail-page and stayed-on-list
//!   states (tolerant of empty alerts data)
//!
//! # Reversibility
//!
//! Pure read — alerts data is server state. Tapping an event opens a
//! detail page (no mutation), btn-back returns to the list. Bottom-tab
//! nav back to home is a single tap.
