 ### Auto-fixed Issues
 
 **1. [Rule 1 - Bug] CalendarCallbacks nested under config.callbacks — not top-level**
+
 - **Found during:** Task 1 — tsc reported `onRangeUpdate` not in `CalendarConfigExternal`
 - **Issue:** Research pattern (RESEARCH.md Pattern 4) showed `onRangeUpdate` at the top level of the config object. The actual type (`CalendarConfigExternal extends Partial<ReducedCalendarConfigInternal>`) carries `callbacks?: CalendarCallbacks` where `CalendarCallbacks` contains `onRangeUpdate` and `onEventClick`. They must be nested under `config.callbacks`.
 - **Fix:** Moved `onRangeUpdate` and `onEventClick` into `callbacks: { ... }` in the `useCalendarApp` config

 **2. [Rule 3 - Blocking] window.matchMedia not defined in jsdom**
+
 - **Found during:** Task 2 — test run crashed at Zustand store initialisation
 - **Issue:** `calendarStore.ts` calls `window.matchMedia` inside `readPersistedView()` which runs at `create()` time — i.e. at module load, before any test-file-level polyfill runs. Inline `Object.defineProperty` in the test file is too late.
 - **Fix:** Created `src/test-setup.ts` with the polyfill; added `setupFiles: ['./src/test-setup.ts']` to `vitest.config.ts`

 ## Threat Flags
 
 No new threat surface beyond the plan's threat model.
+
 - T-02d-01 (XSS): CalendarShell uses React JSX default escaping for all event field rendering — no `dangerouslySetInnerHTML`. Carried to Plan 05 popover.
