+- **2025-12-22 — TypeScript Error Fix**: Fixed JSDoc parse error in definitions.ts
+  - **Root Cause**: The `*/` sequence in cron expression `'0 0 */6 * *'` inside JSDoc example was being interpreted by TypeScript as the end of a JSDoc comment, causing parse errors
+  - **Fix**: Changed cron expression from `'0 0 */6 * *'` to `'0 0,6,12,18 * * *'` (same meaning - every 6 hours) to avoid the `*/` sequence
+  - **Additional Fixes**: Removed problematic JSDoc example from `saveContentCache()` and changed template literal in `getSchedulesWithStatus()` example to string concatenation
+  - **Verification**: TypeScript compiles successfully (0 errors), build passes, all JSDoc examples remain functional
 
 ### Changed
 - **2025-12-22 — P2.6 COMPLETE**: Type safety cleanup — eliminated all `any` usages except documented TypeScript mixin limitation
