+ *    adjustment - [IN] Adjustment string (const char *):                     *
+ *                 - Can be "+num" or "-num" to adjust the current severity   *
+ *                   up or down by the specified amount.                      *
+ *                 - Can be "num" to directly set the severity to the value.  *
+ *                 - If invalid, the current severity is returned unchanged.  *

+ *    - Parses the adjustment string as a signed integer.                     *
+ *    - If the input is valid:                                                *

+ *          [TRIGGER_SEVERITY_NOT_CLASSIFIED, TRIGGER_SEVERITY_DISASTER].     *
+ *    - If the input is invalid or NULL, the severity remains unchanged.      *
