-## Test status
+## Validation status
 
-This is intentionally marked as a **test build** until it has been validated in-game on Turtle WoW 1.18.x. Core mail sending/opening behavior has not been deliberately redesigned; the patch focuses on compatibility and safety around the upstream implementation.
+Version **1.4.6** has been promoted to stable after in-game testing on Turtle WoW 1.18.x completed without Lua errors in the tested setup.
 
-Recommended checks after installing:
-
-1. Open/close the mailbox repeatedly.
-2. Test normal mail, item mail, gold, AH, returned mail, and COD.
-3. Test one-item and multi-item sends.
-4. Test recipient autocomplete.
-5. Test the sent/received log.
-6. If you use pfUI, test with its mailbox skin enabled and disabled.
+The patch intentionally keeps the original send/open workflow instead of redesigning it. Addons that heavily replace or re-parent the Blizzard mail UI can still create compatibility issues; known architectural risks are documented in `AUDIT.md`.
