Estimated code review effort: 2 (Simple) | ~10 minutes Mergeability Score: 🔵 Low · up to The change disables mobile toasts while preserving inline, banner, and copy feedback. Merge readiness is otherwise good, but the regression test should also cover a previously stored enabled preference so stale settings cannot accidentally re-enable toasts. Possibly related PRs

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Seed the former persisted preference in this regression test.
productionInitializerRemainsDisabled never writes a persisted true value. It verifies only the ordinary default path and cannot catch a regression that reads the old beta setting. Set the exact former preference key before constructing ToastCenter, then restore the shared UserDefaults state after the test.
This test is intended to cover the PR objective that persisted beta preferences cannot enable the presenter. As per coding guidelines, “Isolate shared static, global, UserDefaults, file, and related state per test, resetting it in setUp and tearDown as appropriate.”

ToastCenteralways starts disabled, ignores any stored preference, and cannot be enabled from production code.UserDefaultsvalues are ignored.ToastCenterno longer reads/writesUserDefaults; the production initializer uses a fixed disabled policy and exposesisEnabledas public read-only. Tests enable via the internal initializer; the DEBUG gallery still honorsCMUX_TOAST_GALLERY=1.toasts.isEnabled; with the presenter disabled they fall back to the inline chat error banner, the workspace bottom banner, and the “Copy All” checkmark.ToastCenter.enabledDefaultsKeyand any production writes toToastCenter.isEnabled.Written for commit 4d047f4.
