+# 1. Goal
+Refactor the class {{P}}CLIMB_PRICER in package $TMP. The class calculates the
+price of a climbing session at a climbing centre. The booking program of the
+centre calls the class for each session. The class is correct today, but the
+code is hard to read and hard to change. Make the code clean and easy to
+change. The behavior must stay the same.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The class {{P}}CLIMB_PRICER exists in package $TMP. It is active.
+- The booking program calls the method PRICE and then reads the components of
+  the result structure.
+- No user reports a wrong price. All prices are correct.
+- The implementation is one long method with deep nesting and many literal
+  values. A change to one rate is risky.
+
+# 4. Contract
+- Refactor the class {{P}}CLIMB_PRICER in package $TMP. The name stays the
+  same.
+- The class is public and final. It has a public constructor without
+  parameters.
+- The public interface must not change. It is:
+  - TYPES ty_entry TYPE c LENGTH 1.
+  - TYPES ty_amount TYPE p LENGTH 8 DECIMALS 2.
+  - TYPES ty_session with the components entry_type TYPE ty_entry,
+    hours TYPE i, climbers TYPE i, equipment TYPE abap_bool,
+    member TYPE abap_bool and visits TYPE i.
+  - TYPES ty_result with the components base TYPE ty_amount,
+    surcharge TYPE ty_amount, discount TYPE ty_amount, total TYPE ty_amount
+    and message TYPE string.
+  - METHODS price IMPORTING is_session TYPE ty_session
+    RETURNING VALUE(rs_result) TYPE ty_result.
+- Do not add other public methods or public types.
+
+# 5. Business rules
+The legacy code contains all the rules. Read the code of {{P}}CLIMB_PRICER
+before you change it. Each input must give the same result as the legacy code.
+Keep each limit, each rate, each surcharge, each discount and each message
+text.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP. Methods below 40 statements. No global
+  variables. No magic numbers. No comment that restates the code.
+- Out of scope: do not change the public interface of {{P}}CLIMB_PRICER. Do not
+  create other objects.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
