// E2E coverage for keyboard editing in the executive-meetings schedule.
// These tests verify the keyboard contract for the three inline-edit
// cells (time range, title, attendee name):
//
//   - Tab navigation reaches the cell (it is keyboard-reachable via
//     tabIndex=0).
//   - Pressing Enter on the focused display opens edit mode.
//   - Pressing Enter inside the editor saves (PATCH/PUT succeeds,
//     editor collapses to display mode).
//   - Pressing Escape cancels — original value is restored, NO PATCH/PUT
//     is sent, editor collapses.
//   - Focus does not get stranded on an unmounted node after save/cancel
//     (it returns to body or the row, not into the void).
//
// Each scenario seeds its own meeting row on a far-future date so we
// never collide with real schedule data, and afterAll cleanup deletes
// the rows we created.

// Task #308: typing on the keyboard + Enter must save.
//
// The historical bug: the time cell used <input type="time">, which
// only fires onChange when the value is a complete, canonical "HH:MM"
// string. Typing "9:30" without a leading zero, "0930" compact, "9:30
// PM", or Arabic-Indic digits left the controlled React state empty,
// so pressing Enter ran save() with the stale value, equality with
// the saved value short-circuited, no PATCH fired, and the cell
// snapped back to "—" (or the prior value) — looking to the user
// like Enter "didn't save".
//
// These cases exercise each typed shape through the full UI stack
// (keystrokes → React state → save() → PATCH → DB → refetched cell
// text) so a regression at any layer trips a test.
// -------------------------------------------------------------------

// Reusable helper: open a meeting's time cell, focus the start input,
// clear it, type a new value, optionally pick the AM/PM toggle, do
// the same for end, press Enter, and wait for the PATCH + day GET
// refetch.
//
// Per task #315 the time cell is now a 12-hour picker — typing a
// 1–12 hour without first picking AM or PM is intentionally an
// ambiguous parse error (the fix for the "1:15 silently saved as
// AM" bug). For typed shapes that the picker can resolve on its
// own (an explicit AM/PM marker like "9:30 PM", or a 24h-only hour
// like "13:30") `period` should be `null`; for ambiguous shapes
// pass "am" or "pm" so the helper clicks the matching toggle
// before pressing Enter.

// mirror the time-cell tests for the title cell:
//
//   1. With the PATCH delayed 1500 ms, the cell shows the new title
//      within ~300 ms — proves the optimistic cache write repaints
//      the read-only display before the network round-trip resolves.
//   2. With the PATCH stubbed to 500, the cell rolls back to the
//      original title and an error toast surfaces — proves the
//      rollback path actually restores cache state.
//   3. Attendee-name save shows the renamed attendee instantly with
//      the PATCH delayed — proves the optimistic pattern covers the
//      attendees PUT endpoint too, not just the meeting PATCH.
