 **Two Classes - Strict Separation**: `Rsx_Time` (datetimes with timezone) | `Rsx_Date` (calendar dates, no timezone)
 
+**String-Based Philosophy**: RSpade uses ISO strings, not Carbon objects. Dates are `"2025-12-24"`, datetimes are `"2025-12-24T15:30:00-06:00"`. Same format in PHP, JavaScript, JSON, database queries. No object serialization issues.

+**Model Casts**: `Rsx_Model_Abstract` auto-applies `Rsx_Date_Cast` (DATE columns) and `Rsx_DateTime_Cast` (DATETIME columns). Never define `$casts` with `'date'`, `'datetime'`, or `'timestamp'` - these use Carbon and are blocked by `rsx:check`.

 **SPA routes ARE server routes.** If you get 404, the route doesn't exist - check route definitions. Never dismiss as "SPA can't be tested server-side".
 
+**rsx:debug captures the fully-rendered final DOM state** after all async operations, component lifecycles, and data loading complete. If the DOM doesn't match expectations, it's not a timing issue - what you see is what the user sees. Investigate the actual code, not the capture timing.
