+Runs in the background; nobody polls it. It
+  - starts plan 2 generation (3 workers, hard and error share raised, no fixed target) when the first plan has
+    ended, until --gen-deadline or the budget guard; adds K (free-text) variants at about 10 % of the other tasks;
+  - runs trajectories with 2 workers (1 after any A4H error), at most 2 attempts per task: a second attempt only
+    when the first one failed or was accepted without a repair;
+  - writes a summary to train/STATE.md and docs/yol-haritasi.md every 50 accepted trajectories, and commits;
+  - stops and reports (runs/pipeline/STOPPED.txt, STOP flag for the generators) when: acceptance over the last
+    30 runs is below 50 %, one harness error pattern appears 3 times, the budget guard stops, or the deadline.

+# 1. Goal
+Show the weight check of each container at a container terminal. A report and an
+OData service will read the check, so the calculation must be in the database,
+in a CDS view.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}CONT (container master), package $TMP. Key: CONT_ID (CHAR 10).
+  Fields: CUSTOMER (CHAR 10), DECL_KG (DEC 15,2, declared weight in kilograms),
+  MAX_KG (DEC 15,2, maximum permitted weight in kilograms).
+- Table {{P}}WEIGH (weighbridge record), package $TMP. Key: CONT_ID (CHAR 10).
+  Field: MEAS_KG (DEC 15,2, measured weight in kilograms).
+
+# 4. Contract
+- Create the CDS view entity {{P}}I_CONT_WEIGHT in package $TMP.
+- Elements, with these names: CONT_ID (key), CUSTOMER, DECL_KG, MEAS_KG,
+  DEVIATION_KG, DEVIATION_PCT, STATUS.
+- No authorization check (#NOT_REQUIRED).
+
+# 5. Business rules
+1. Show one row for each container that has a weighbridge record. Do not show a
+   container without a weighbridge record.
+2. DEVIATION_KG is the difference between MEAS_KG and DECL_KG, without a sign.
+   It is always positive or zero and it has 2 decimals.
+3. DEVIATION_PCT is DEVIATION_KG as a percentage of DECL_KG. It has 2 decimals.
+4. STATUS is 'HOLD' if MEAS_KG is greater than MAX_KG.
+5. STATUS is 'WARN' if rule 4 is not true and DEVIATION_PCT is greater than 5.
+6. STATUS is 'LOAD' in all other cases.
+7. DECL_KG is always greater than zero.
+
+# 6. Constraints
+- Release target: 8.16.
+- Use Clean ABAP. Keep every method below 40 statements.
+- Out of scope: do not change {{P}}CONT and {{P}}WEIGH.
+
+# 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.

+# 1. Goal
+A vineyard cooperative collects the harvest reports of its members. The
+cooperative needs one evaluation of the harvest for each grape variety. A
+planning program calls the evaluation before it plans the transport of the
+grapes to the winery.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_HARVEST exists in package $TMP. It is active.
+- The interface contains the data types for the harvest reports, for the member
+  master data, and for the result. Read the interface before you start to work.
+- A harvest report has a member, a grape variety, and a quantity in kilograms.
+- The member master data has a member ID and a member name.
+
+# 4. Contract
+- Create the class {{P}}HARVEST_EVALUATOR in package $TMP.
+- The class is public and final. It has a public constructor without
+  parameters.
+- The class has one public method:
+  EVALUATE
+    IMPORTING it_report        TYPE {{P}}IF_HARVEST=>TT_REPORT
+              it_member        TYPE {{P}}IF_HARVEST=>TT_MEMBER
+    RETURNING VALUE(rt_result) TYPE {{P}}IF_HARVEST=>TT_RESULT.
+- Do not add other public methods.
+
+# 5. Business rules
+A harvest report is countable when rule 1 and rule 2 are true.
+1. The member_id of the report occurs in it_member. A member_id occurs at most
+   one time in it_member.
+2. The quantity_kg of the report is greater than 0.
+3. Group the countable reports by variety. Create one result row for each
+   variety that has at least one countable report.
+4. The total_kg of a result row is the sum of the quantity_kg of all countable
+   reports of the variety.
+5. The member_count of a result row is the number of different member_id
+   values in the countable reports of the variety.
+6. Sort the result rows by total_kg in descending order. When two rows have the
+   same total_kg, sort these rows by variety in ascending order.
+7. When no report is countable, return an empty table.
+
+# 6. Constraints
+- Release target: 8.16.
+- 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_HARVEST.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.

+# 1. Goal
+The optician shop uses the class {{P}}GLASSES_PRICER to calculate the price of a
+glasses order. A sales program calls the class for each quotation. The class is
+legacy code. It is hard to read and hard to test. Refactor the class. The
+behavior must stay the same.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The class {{P}}GLASSES_PRICER exists in package $TMP. It is active.
+- The class is public and final. It has a public constructor without parameters.
+- The public interface of the class is:
+  - the type TY_AMOUNT (packed number, length 9, 2 decimals),
+  - the type TY_LENS (character, length 1),
+  - the type TY_COAT (character, length 1),
+  - the method PRICE with the importing parameters IV_FRAME (TY_AMOUNT),
+    IV_LENS (TY_LENS), IV_COAT (TY_COAT), IV_QTY (TYPE i) and the returning
+    parameter RV_PRICE (TY_AMOUNT).
+- The program {{P}}OPTIC_QUOTE_RPT calls the class.
+- The legacy implementation is the specification of the behavior.
+
+# 4. Contract
+- Refactor the class {{P}}GLASSES_PRICER in package $TMP. The name stays the same.
+- The class stays public and final and keeps its public constructor without
+  parameters.
+- Keep the public types TY_AMOUNT, TY_LENS and TY_COAT.
+- Keep the method PRICE with the same parameter names, the same parameter types
+  and the same sequence.
+- Do not add public methods or public attributes.
+- Do not create other objects.
+
+# 5. Business rules
+- The behavior of the class must not change. For every input, PRICE must return
+  the same value as the legacy method.
+- The legacy code holds all rules, including its limits and its default values.
+- Do not add a rule. Do not remove a rule. Do not correct a rule.
+- PRICE returns a price in the currency of the order.
+
+# 6. Constraints
+- Release target: ABAP Platform 2025 (SAP_BASIS 816).
+- Coding standards: Clean ABAP. One method does one thing. Method length below
+  40 statements. No deep nesting. No magic numbers: use constants. No duplicated
+  code. No dead code. No global variables. No comment that restates the code.
+- Out of scope: do not change the program {{P}}OPTIC_QUOTE_RPT. Do not change
+  the public interface of the class.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.

+# 1. Goal
+A drone delivery operator checks a delivery request before it releases a drone.
+The dispatch program calls one check for each request. The program needs one
+reason code for each request and the battery charge that the flight needs.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_DRONE_CHECK exists in package $TMP. It is active.
+- The interface has the types TY_REASON (character, length 10), TY_WEIGHT
+  (packed number, length 8, 2 decimals), TY_DISTANCE (packed number, length 8,
+  2 decimals), TY_SPEED (packed number, length 8, 2 decimals) and TY_PERCENT
+  (integer).
+- The interface has the constant structure C_REASON with the components OK,
+  PAYLOAD, DISTANCE, WIND, BATTERY, ZONE and LIGHT.
+- The interface has one method:
+  CHECK
+    IMPORTING iv_payload          TYPE ty_weight
+              iv_distance         TYPE ty_distance
+              iv_wind_speed       TYPE ty_speed
+              iv_battery          TYPE ty_percent

+              iv_daylight         TYPE abap_bool
+    RETURNING VALUE(rv_reason)    TYPE ty_reason.
+
+# 4. Contract
+- Create the class {{P}}DRONE_CHECKER in package $TMP.
+- The class is public, final, and has a public constructor without parameters.
+- The class implements {{P}}IF_DRONE_CHECK.
+- The class has the public method REQUIRED_BATTERY:
+  IMPORTING iv_distance TYPE {{P}}IF_DRONE_CHECK=>TY_DISTANCE
+  RETURNING VALUE(rv_percent) TYPE {{P}}IF_DRONE_CHECK=>TY_PERCENT.
+- Do not add other public methods.
+
+# 5. Business rules
+The payload is in kilograms, the distance in kilometres, the wind speed in
+metres per second, and the battery charge in percent.
+The check applies the rules in this sequence and returns the reason of the
+first rule that fails.
+1. If the payload is less than or equal to zero, or greater than 5.00, return
+   PAYLOAD.
+2. If the distance is less than or equal to zero, or greater than 20.00, return
+   DISTANCE.
+3. If the wind speed is greater than 12.00, return WIND.
+4. If the battery charge is less than the charge that the flight needs, return
+   BATTERY.
+5. If iv_in_zone is abap_false, return ZONE.
+6. If iv_daylight is abap_false, return LIGHT.
+7. Else return OK.
+The charge that a flight needs is the result of REQUIRED_BATTERY:
+- If the distance is less than or equal to zero, the result is 0.
+- Else the result is 2 percent for each started kilometre plus a reserve of
+  10 percent. A started kilometre counts as a full kilometre.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816 (ABAP Platform 2025).
+- 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_DRONE_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.

+# 1. Goal
+Check a hot-air balloon flight before the launch. The flight office calls the
+check for each planned flight. The check must stop a flight when a limit is
+exceeded. The caller needs one exception for each reason.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The exception class {{P}}CX_BALLOON_FLIGHT exists in package $TMP. It is
+  active. It inherits from CX_STATIC_CHECK. It has the public read-only
+  attribute MV_TEXT (type string) and a constructor with the importing
+  parameter IV_TEXT (type string). The constructor writes IV_TEXT to MV_TEXT.
+- The flight office knows four figures of a flight: the number of passengers,
+  the total take-off weight in kilograms, the wind speed in kilometres per
+  hour, and the height of the cloud base in metres.
+
+# 4. Contract
+- Create the class {{P}}BALLOON_CHECKER in package $TMP.
+  - The class is public and final. It can be created without constructor
+    parameters.
+  - The class has the public method CHECK_FLIGHT with these parameters:
+    - importing IV_PASSENGERS type i
+    - importing IV_WEIGHT_KG type i
+    - importing IV_WIND_KMH type i
+    - importing IV_CLOUD_BASE_M type i
+    - returning RV_FREE_KG type i
+    - raising {{P}}CX_BALLOON_FLIGHT
+  - Do not add other public methods.
+- Create these exception classes in package $TMP. Each class inherits from
+  {{P}}CX_BALLOON_FLIGHT.
+  - {{P}}CX_BALLOON_CREW with the constructor importing IV_PASSENGERS type i
+    and IV_LIMIT type i.
+  - {{P}}CX_BALLOON_WEIGHT with the constructor importing IV_WEIGHT_KG type i
+    and IV_LIMIT_KG type i.
+  - {{P}}CX_BALLOON_WIND with the constructor importing IV_WIND_KMH type i and
+    IV_LIMIT_KMH type i.
+  - {{P}}CX_BALLOON_CLOUD with the constructor importing IV_CLOUD_BASE_M type i
+    and IV_LIMIT_M type i.
+  - Each constructor writes the message text to MV_TEXT. Rule 1 to rule 4 of the
+    business rules give the text of each exception.
+
+# 5. Business rules
+The method CHECK_FLIGHT applies the rules in this sequence. It raises the
+exception of the first rule that fails. If no rule fails, the method returns the
+free payload.
+
+1. Passengers. The limit is 8. If IV_PASSENGERS is greater than 8, raise
+   {{P}}CX_BALLOON_CREW. The message text is
+   "Passengers <passengers> exceeds the limit <limit>". Example: 12 passengers
+   give the text "Passengers 12 exceeds the limit 8".
+2. Weight. The limit is 640 kilograms. If IV_WEIGHT_KG is greater than 640,
+   raise {{P}}CX_BALLOON_WEIGHT. The message text is
+   "Weight <weight> kg exceeds the limit <limit> kg". Example: 700 kilograms
+   give the text "Weight 700 kg exceeds the limit 640 kg".
+3. Wind. The limit is 18 kilometres per hour. If IV_WIND_KMH is greater than 18,
+   raise {{P}}CX_BALLOON_WIND. The message text is
+   "Wind <wind> km/h exceeds the limit <limit> km/h". Example: 25 kilometres per
+   hour give the text "Wind 25 km/h exceeds the limit 18 km/h".
+4. Cloud base. The limit is 300 metres. If IV_CLOUD_BASE_M is less than 300,
+   raise {{P}}CX_BALLOON_CLOUD. The message text is
+   "Cloud base <cloud base> m is below the limit <limit> m". Example: 200 metres
+   give the text "Cloud base 200 m is below the limit 300 m".
+5. Free payload. If no rule fails, the free payload is 640 minus IV_WEIGHT_KG.
+   Return the free payload in RV_FREE_KG.
+
+# 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}}CX_BALLOON_FLIGHT.
+
+# 7. Acceptance
+- The classes are active and have no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.

+# 1. Goal
+
+A furniture shop sells furniture on instalment plans. A checkout program calls one
+check before the shop grants an instalment plan to a customer. The program needs
+one reason code for each customer.
+
+# 2. Open questions
+
+None.
+
+# 3. Context
+
+- The interface {{P}}IF_CREDIT_CHECK exists in package $TMP. It is active.
+- The interface declares the type of the reason, the type of a money amount, the
+  constants of the reason codes, and one method.
+- The method name, the parameter names and the parameter types are not in this
+  document. Read the interface in the system.
+- The reason constants have the names OK, AGE, INCOME, OPEN_PLAN and LIMIT.
+
+# 4. Contract
+
+- Create the class {{P}}CREDIT_CHECKER in package $TMP.
+- The class is public and final. It has a public constructor without parameters.
+- The class implements the interface {{P}}IF_CREDIT_CHECK.
+- Do not add other public methods.
+
+# 5. Business rules
+
+The check receives the age of the customer in years, the net monthly income of the
+customer, the number of open instalment plans of the customer, and the amount of
+the new order. Apply the rules in this sequence. Return the reason of the first
+rule that fails.
+
+1. If the age is less than 18, return AGE.
+2. If the net monthly income is zero or less, return INCOME.
+3. If the number of open instalment plans is 2 or more, return OPEN_PLAN.
+4. Calculate the credit limit:
+   - Start with three times the net monthly income.
+   - Subtract 500 for each open instalment plan.
+   - If the age is less than 21, halve the limit and round the result down to
+     whole euros. Example: 3750.75 becomes 3750.00.
+5. If the amount of the new order is more than the credit limit, return LIMIT.
+6. Else return OK.
+
+# 6. Constraints
+
+- Release target: SAP_BASIS 8.16 (ABAP Platform 2025).
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change the interface {{P}}IF_CREDIT_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.

+# 1. Goal
+An auction house charges a buyer's premium on each lot that it sells. The
+auction program calls one premium module for each sold lot. The premium module
+must use the same interface as the sample module {{P}}AUC_SAMPLE, because the
+auction program calls all premium modules in the same way.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Function group {{P}}FG_AUCT exists in package $TMP.
+- Function module {{P}}AUC_SAMPLE exists in this group. It is the sample
+  premium module. Its interface is the interface that all premium modules must
+  use.
+
+# 4. Contract
+- Create the function module {{P}}AUC_PREMIUM in function group {{P}}FG_AUCT.
+- Use exactly the interface of {{P}}AUC_SAMPLE: the same parameter names, kinds,
+  types, and exceptions.
+- The exception is INVALID_HAMMER.
+
+# 5. Business rules
+1. If the hammer price is less than 0, raise the exception INVALID_HAMMER and
+   stop.
+2. Set the skip flag to false, except in rule 3.
+3. Lot type C (charity): set the skip flag to true. Leave the fee unchanged and
+   stop.
+4. For every other lot type, calculate the band premium from the hammer price:
+   - the part of the hammer price up to 1,000.00: 20 %
+   - the part of the hammer price above 1,000.00 up to 10,000.00: 12 %
+   - the part of the hammer price above 10,000.00: 6 %
+5. Channel O (online): the premium is 90 % of the band premium. For every other
+   channel the premium is the band premium.
+6. Round the premium of rule 5 half up to 2 decimals.
+7. The minimum premium is 5.00. The maximum premium is 5,000.00.
+8. The fee is the premium of rules 4 to 7.
+
+# 6. Constraints
+- Release target: 7.02. The code must run on a 7.02 system. Do not use syntax
+  that was introduced after release 7.02.
+- Coding standards: Clean ABAP.
+- Out of scope: do not change {{P}}AUC_SAMPLE.
+
+# 7. Acceptance
+- The function module is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests for the function module in a global test class.
