Picked the 3 most isolated items from the 7-item umbrella; deferred the rest as #259/#260/#261. #223 + #224 — singular toast + summary on partial failure (T001): - my-orders.tsx: replaced the N=1 vs N>1 ternary in scheduleDelete with a single t("myOrders.clearedCount", { count }) so i18next picks _one / _other automatically. Single-row delete now flows through this same toast too — user-visible copy for N=1 is now "1 order deleted" / "تم حذف طلب واحد" instead of the legacy "Order deleted" / "تم حذف الطلب". - my-orders.tsx: partial-failure path now shows ONE summary toast using the existing clearedPartial key ("{{ok}} deleted, {{fail}} failed") instead of N error toasts. Total failure (okCount===0) keeps deleteFailed. - Updated 3 Playwright specs that asserted the legacy copy: order-clear-finished-undo (already had the singular case), order-undo-toast (Arabic single-row delete), order-delete-flush-on-unmount (English). Note: the legacy "myOrders.deleted" locale key is now unreferenced in source — left in place to avoid noise; deletion can be handled separately. #238 — opt-out coverage in executive-meetings-notifications.test.mjs (T002): - Appended 4 tests + setPref/clearPref helpers covering filterRecipientsByNotificationPref: inApp=false drops user, missing pref defaults to ON, cross-event isolation (mute on event A leaves event B alone), email=false leaves in-app intact. Helpers use ON CONFLICT on the verified unique index. Some scenarios overlap existing tests in executive-meetings.test.mjs (lines 1764, 1809) — these still add value by exercising the meeting_created socket fan-out path and cross-event isolation, which the existing tests don't cover. #236 — Restore defaults endpoint + button (T003): - Server: added DELETE /api/executive-meetings/notification-prefs after PUT. Scoped strictly to req.session.userId, returns {ok, count}. Reuses requireExecutiveAccess guard. Architect confirmed no cross-user leakage. - Client: restoreDefaults() handler + outline button (data-testid "em-pref-restore-defaults", NOT gated on dirty since the whole point is to blow away saved settings). New i18n keys restoreDefaults / restored in both locales. - Architect found a stale-state race in restoreDefaults: setDraft(null) was called before invalidateQueries, letting the seed effect repopulate draft from still-cached pre-DELETE data. Fixed by inverting the order to match save() — invalidate first (await refetch), then setDraft(null). - Tests: appended 2 integration tests to executive-meetings.test.mjs covering the full restore flow (PUT 2 muted prefs → DELETE → assert {ok,count:2} + GET shows defaults + actual fan-out reaches user again) and idempotent no-op DELETE on a user with no rows. Test results: - executive-meetings.test.mjs: 47/47 pass (incl. 2 new DELETE tests) - executive-meetings-notifications.test.mjs: 11/11 pass (incl. 4 new opt-out tests) - Playwright order specs: 6/6 pass after legacy-copy updates - Pre-existing failures in service-orders + meeting_created fan-out are untouched and not caused by this change. Follow-ups proposed: #259 (beforeunload + tab-close Playwright), #260 (admin override another user's prefs with audit row + UI), #261 (iPad header verification — may already work).
