+# 1. Goal
+A vehicle inspection station checks a vehicle before it gives a test
+certificate. The check returns one reason code for each vehicle.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_INSPECTION_CHECK exists in package $TMP. It is active.
+- The interface has the type of the reason code, one constant for each reason
+  code, and one method that checks a vehicle.
+- Read the interface. It gives the exact method name, the parameters and the
+  type of the return value. This specification does not repeat the signature.
+
+# 4. Contract
+- Create the class {{P}}INSPECTION_CHECKER in package $TMP.
+- The class is public and final. It has a public constructor without parameters.
+- The class implements {{P}}IF_INSPECTION_CHECK.
+- Do not add other public methods.
+
+# 5. Business rules
+Apply the rules in this sequence. Return the reason code of the first rule that
+fails.
+1. Remove all spaces from the plate. Convert all letters to upper case. If the
+   result is empty, return the reason code for a missing plate (NO_PLATE).
+2. Remove all spaces from the make. Convert all letters to upper case. If the
+   result is empty, return the reason code for a missing make (NO_MAKE).
+3. If the first registration date is initial or after the check date, return the
+   reason code for a bad registration date (REG_DATE).
+4. Calculate the age of the vehicle. The age is the number of full years between
+   the first registration date and the check date. If the age is 30 years or
+   more, return the reason code for an old vehicle (TOO_OLD).
+5. If the mileage is less than zero, return the reason code for a bad mileage
+   (MILEAGE).
+6. If the brake performance is less than 50 percent, return the reason code for
+   weak brakes (BRAKES).
+7. If the exhaust value is more than 1000 ppm, return the reason code for a bad
+   exhaust value (EXHAUST).
+8. Else return the reason code for a passed check (OK).
+
+# 6. Constraints
+- Release target: ABAP Platform 2025 (SAP_BASIS 816).
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change {{P}}IF_INSPECTION_CHECK.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
