+# 1. Goal
+Refactor the legacy class {{P}}PARKING_PRICER in package $TMP. A car park
+operator uses the class to price a parking session. The class must keep its
+public interface and must return the same fee as before for every input.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The class {{P}}PARKING_PRICER exists in package $TMP. It is active.
+- The class is the contract object of this task. Refactor it in place. Keep the
+  class name, the package and the public interface.
+- A checkout terminal calls the method calculate_fee for each parking session
+  and prints the returned fee.
+- The legacy implementation contains the business rules. Read the legacy code
+  before you change it.
+
+# 4. Contract
+- Class {{P}}PARKING_PRICER in package $TMP. Public, final, create public.
+- Public type ty_vehicle (c length 1).
+- Public type ty_fee (p length 8, 2 decimals).
+- Public constants:
+  c_vehicle_car = 'C', c_vehicle_motorcycle = 'M', c_vehicle_van = 'V'.
+- Public method:
+  calculate_fee
+    IMPORTING iv_minutes     TYPE i
+              iv_vehicle     TYPE ty_vehicle
+              iv_lost_ticket TYPE abap_bool
+    RETURNING VALUE(rv_fee)  TYPE ty_fee.
+- Do not add other public methods. Do not change the signature.
+
+# 5. Business rules
+The behavior stays the same. The legacy implementation in package $TMP is the
+only source of the rules. For every combination of iv_minutes, iv_vehicle and
+iv_lost_ticket the refactored class must return the same fee as the legacy
+class.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816 (ABAP Platform 2025).
+- Coding standards: Clean ABAP. Methods below 40 statements. No magic numbers.
+  No deep nesting. No duplicated code. No comment that restates the code. No
+  global variables.
+- Out of scope: the public interface of {{P}}PARKING_PRICER. Do not rename,
+  remove or add public types, constants or methods.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
+- No ATC priority 1 or priority 2 finding.
