//! v3.8 c2 — dogfood usecase: search filter modal (multi-stage).
//!
//! Port reference: `insight/tools/maestro/flows/main/search-filter.yaml`.
//! Drives the Search filter modal through three stages: open → Reset
//! chip → reopen → optional spatial+index probe of first device row
//! below the "Device" header → Apply → verify returned to Search root.
//!
//! # Why this dogfood
//!
//! Cross-surface validation of:
//!
//! - **v3.7 c2 spatial+index modifier on a distinct modal**: this is
//!   the second business surface for `Modifiers { below + nth }`. v3.7
//!   c2 ran it on People recent list (a tall scroll list under
//!   "Today|Yesterday"). v3.8 c2 runs the same compound on a filter
//!   modal's device list under "Device" — different ancestor / scroll
//!   container / RN list virtualisation strategy.
//! - **multi-stage modal flow**: open → dismiss-via-Reset → reopen.
//!   Stresses the v3.5 c1 topmost_modal_filter against a modal that
//!   appears, dismisses, and reappears in one flow. If state leaks
//!   between stages (e.g. stale candidate cache), this surfaces it.
//! - **Apply button**: text-selector tap that closes the modal and
//!   commits state. Closes the multi-stage cycle.
//!
//! # Reversibility
//!
//! Pure read — filter selection is local + transient. Reset chip wipes
//! between stages; the example doesn't drive anything destructive.
