//! v3.17 c1 — dogfood usecase: alerts rules list + first-rule drilldown.
//!
//! Port reference: `insight/tools/maestro/flows/main/alerts-rules.yaml`
//! & `insight/tools/maestro/subflows/{launch-warm,go-to-alerts}.yaml`.
//! Drives the Alerts bottom-tab → Rules list (default sub-tab on
//! `screen-alerts`) → optional tap into first rule's events page →
//! verify either events list / empty state / stayed on rules list →
//! optional back via `btn-back`.
//!
//! # Why this dogfood
//!
//! Alerts surface in insight has three parallel sub-tabs (Counting /
//! Dwell-time / Rules-events). v3.9 c1 covered Counting; v3.16 c2
//! covered Counting fullscreen. Rules-list path is the third leg —
//! exercises the **default** sub-tab state immediately after
//! `screen-alerts` mounts (no extra sub-tab tap), the first-rule
//! drilldown via regex+nth=0, and the `btn-back` id-selector exit.
//!
//! Also exercises:
//!
//! - launch_warm subflow port (stopApp → openLink deep-link → wait
//!   landing|home) — first dogfood to drive deep-link cold-warm via SDK
//! - id-selector optional tap (`btn-back`) with graceful no-op
//! - extendedWaitUntil pattern via wait_for + text-regex with broad
//!   OR-set covering both "rules present" and "empty/event-page"
//!
//! # Reversibility
//!
//! Pure read — alert rules list is server config, view-only. Tap into
//! a rule opens the events page (also view-only). `btn-back` is single
//! tap restoring previous screen.
//!
//! # Capability gap surfaced
//!
//! None planned. If alert rules list is empty (only "No alerts found"
//! visible), drilldown skipped gracefully — flow still asserts terminal
//! visibility regex passes on empty path.
