+# Repo Working Notes
+
+- Verify the actual file, class name, and call site before changing a library/controller reference.
+- If a class load error appears, check the existing library file and the current repo usage pattern first.
+- Do not swap to a different library name on assumption alone.
+- Keep fixes minimal and local unless the user asks for a broader refactor.
+- If a task changes live DB objects such as table schema, trigger, stored procedure, or function, always add a SQL record file under `sql/manual_changes/`.
+- Name the SQL record file with the pattern `YYYY-MM-DD-<commit-message-stem>.sql`.
+- The SQL record file must include the actual SQL change that was applied, not just a note.

+-- Target: devone / one_lab
+-- Reason:
+--   t_orderdetail_au failed on UPDATE with:
+--   ERROR 1136 (21S01): Column count doesn't match value count at row 1
+-- Root cause:
+--   INSERT into one_lab_log.log_orderdetail listed Log_OrderDetailCreated
+--   but did not provide a corresponding VALUES entry.
+-- Fix:
+--   restore the trigger and add NOW() for Log_OrderDetailCreated.
