+# 1. Goal
+Refactor the legacy class {{P}}TAILOR_PRICER in package $TMP. The class calculates
+the price of an alteration job in a tailor shop. The shop terminal calls the class
+for each job. The behavior of the class must stay the same.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The class {{P}}TAILOR_PRICER exists in package $TMP. It is active.
+- The class is public and final. The public constructor has no parameters.
+- The shop terminal calls the public method CALCULATE_PRICE for each job.
+- The legacy implementation is correct. It is also long, deeply nested, and full of
+  magic numbers. It is hard to read and hard to change.
+- The customers do not accept different prices. The same input must give the same
+  result as before.
+
+# 4. Contract
+- The class {{P}}TAILOR_PRICER stays in package $TMP. Do not rename it.
+- The class stays public and final. The public constructor stays without parameters.
+- The public types ty_garment, ty_service, and ty_price stay unchanged.
+- The public method stays unchanged:
+  calculate_price
+    IMPORTING iv_garment      TYPE ty_garment
+              iv_service      TYPE ty_service
+              iv_quantity     TYPE i
+              iv_express      TYPE abap_bool
+    RETURNING VALUE(rv_price) TYPE ty_price.
+- Do not add other public methods, public attributes, or public types.
+
+# 5. Business rules
+The legacy implementation of {{P}}TAILOR_PRICER defines the price rules. Read the
+legacy code in the seed object. Keep every rule, the sequence of the rules, and all
+special cases. The behavior stays the same for every input combination.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816.
+- Coding standards: Clean ABAP. Methods below 40 statements. Maximum nesting depth
+  of 3. No magic numbers, use constants. No global variables. No comment that
+  restates the code.
+- Out of scope: do not change the public interface. Do not change the class name.
+  Do not add public members. Do not change the price rules.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests as local test classes in the class.
