//! v5.0 C1 — capability segment dispatcher.
//!
//! One async fn per cell of the C1 cover matrix (37 capabilities)
//! against the in-repo SelftestFixture SwiftUI app (bundle
//! `dev.smix.SelftestFixture`). Each segment captures its own try/catch,
//! records a `Passed` / `Failed` / `Skipped` result + a [`Narration`]
//! block on the shared [`super::Harness`], and never short-circuits — a
//! fail in segment N still lets the remaining segments run, so the run
//! produces the full matrix even when the fixture is degraded.
//!
//! The scenario reads as a linear, multi-screen user journey:
//!
//! 1. Phase 0 — pure / setup probes (planner, selector factories).
//! 2. Phase 1 — login screen sense (tree / describe / screenshot /
//!    selector factories / find* / system_popups).
//! 3. Phase 2 — login form interaction (fill / focused / press_key /
//!    clear / hide_keyboard / tap / tap_with_mode → Home).
//! 4. Phase 3 — Home dashboard assertions + delayed wait + camera
//!    permission popup (assert_visible / assert_enabled / assert_text /
//!    wait_for / system_popup_action / scroll / swipe_once).
//! 5. Phase 4 — navigation (tap_at_coord / open_url / foreground /
//!    go_back).
//! 6. Phase 5 — lifecycle error paths (install / uninstall / terminate).
//!
//! Phase ordering is load-bearing — segments later in the list assume
//! earlier segments left the fixture in a known state.

// XCTest gesture chain (the same call shape maestro CLI uses). Real-sim
// probe still fails — XCUITest reports `Tap "<id>" Button` but the SwiftUI
// `.sheet`/`.alert`/`.confirmationDialog`/`.fullScreenCover` dismiss closure
// never runs (button remains visible after 5s wait). Root cause sits below
// the XCUITest gesture chain in iOS 17+ modal-window hit-target routing /
// SwiftUI tap-recognizer attachment timing — beyond a single-cp surgical
// fix, so it's recategorized as (c) v5.4+ backlog (tag `v5.x-backlog-c4`).
// Maestro CLI's `_run_all.sh` still passes the same flows; the gap is
// specific to smix's SwiftUI-modal hit-target path.
