Hard batch G0022-G0026: 5/5 accepted; budget floor, CDS checks, mutation check

- generator: budget floor (2x oracle activations, 3x calls), static checks for CDS
  $parameters and UNION annotation
- harness/mutation.py: deterministic mutants of the reference; hidden tests must fail
- G0022 revalidated with harness fixes: oracle 100, null 0
- results in docs/faz1-tasarim.md 11f

+# 1. Goal
+Give the sales figures of each product for a period. The period is an input of the
+view. A report and an OData service read the figures, so the calculation must be in
+the database, in a CDS view.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}SALES (sales line), package $TMP. Key: DOC_ID (CHAR 10), ITEM_NO (INT4).
+  Fields: PRODUCT (CHAR 10), QUANTITY (INT4), PRICE (DEC 15,2, the price of one
+  unit), SOLD_ON (DATS, the date of the sale).
+- The class {{P}}SEED_SALES fills {{P}}SALES with sample data. Run it if you want to
+  test the view manually.
+
+# 4. Contract
+- Create the CDS view entity {{P}}I_SALES_REPORT in package $TMP.
+- Input parameters, with these names and types: P_FROM (DATS), P_TO (DATS).
+  The parameters have no default value.
+- Elements, with these names: PRODUCT (key), TOTAL_QTY, TOTAL_AMOUNT.
+- No authorization check (#NOT_REQUIRED).
+
+# 5. Business rules
+1. A sales line is in the period when SOLD_ON is not before P_FROM and not after
+   P_TO. P_FROM and P_TO are part of the period.
+2. Show one row for each product with at least one sales line in the period. Do not
+   show a product without a sales line in the period.
+3. TOTAL_QTY is the sum of QUANTITY of all sales lines of the product in the period.
+4. TOTAL_AMOUNT is the sum of QUANTITY multiplied by PRICE of all sales lines of the
+   product in the period, with 2 decimals.
+
+# 6. Constraints
+- Release target: 7.58.
+- Coding standards: Clean ABAP.
+- Out of scope: do not change {{P}}SALES and {{P}}SEED_SALES.
+
+# 7. Acceptance
+- The view is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests with CL_CDS_TEST_ENVIRONMENT in a global test class.
