//! v3.7 c3 — dogfood usecase: manage devices (text-selector path).
//!
//! Port reference: `insight/tools/maestro/flows/main/manage-devices.yaml`.
//! Exercises the drawer-routed Manage Devices screen with a text-only
//! input flow: tap a placeholder-labelled search field, type "cam",
//! erase it. No id selectors on the input — the whole input subflow
//! drives off text matching.
//!
//! # Why this dogfood
//!
//! Cross-surface validation of v3.6 c2 fill dispatch + v3.7 c1 clear
//! dispatch on the **text-selector path** rather than the id path.
//! Every prior dogfood (lang switch / device detail / Merlin chat /
//! search-vehicle / search-modal / search-person) drove fill+clear off
//! an explicit `id("input-search")` selector — host-resolve focuses
//! the target before /fill or /clear hits with `_focused_`. This flow
//! uses `text("Search devices")`, which on pure-Text selectors takes
//! the **fast path** (direct /fill or /clear with `{ text: "..." }`
//! payload, no /tree round-trip, no preceding tap). If runner-side
//! NSPredicate match works on the placeholder-text element, the path
//! commits as expected. If not, a real new cap-gap surfaces here.
//!
//! Also exercises:
//!
//! - drawer navigation via inline `open_menu` (cross-validate v3.4 c4
//!   3-retry pattern on the drawer-resident Manage Devices entry)
//! - placeholder-text-as-selector — first dogfood that taps an input
//!   identified by its placeholder string
//!
//! # Reversibility
//!
//! Pure read — the search string is local + transient. erase brings
//! the field back to empty. Closing the drawer and tapping a bottom
//! tab returns home; the example doesn't drive anything destructive.
