+# 1. Goal
+
+A fishing cooperative auctions the catch of its boats. Each boat reports its catch
+as a list of entries. The auctioneer needs one consolidated list for each species.
+A program calls the class before it prints the auction list.
+
+# 2. Open questions
+
+None.
+
+# 3. Context
+
+- Package $TMP.
+- The class is new. No other object exists for this task.
+
+# 4. Contract
+
+Create the class {{P}}FISH_AUCTION in package $TMP.
+
+- The class is public and final.
+- The class has a public constructor without parameters.
+- Public types:
+  - TY_SPECIES: character, length 10.
+  - TY_BOAT_ID: character, length 10.
+  - TY_CATCH: structure with the components BOAT_ID (type ty_boat_id),
+    SPECIES (type ty_species), and WEIGHT_KG (type i).
+  - TT_CATCH: table type of ty_catch. The table can hold more than one entry
+    with the same boat ID and the same species.
+  - TY_SUMMARY: structure with the components SPECIES (type ty_species),
+    TOTAL_WEIGHT (type i), and BOAT_COUNT (type i).
+  - TT_SUMMARY: table type of ty_summary.
+- Public methods:
+  - SUMMARIZE, importing IT_CATCH type tt_catch, returning VALUE(RT_SUMMARY)
+    type tt_summary.
+  - BEST_SPECIES, importing IT_CATCH type tt_catch, returning VALUE(RV_SPECIES)
+    type ty_species.
+- Do not add other public methods.
+
+# 5. Business rules
+
+SUMMARIZE:
+
+1. Do not change the input table.
+2. For each entry, build the species key: remove the leading and the trailing
+   blanks from SPECIES and convert all letters to upper case.
+3. Ignore the entry if the species key is empty. Ignore the entry if WEIGHT_KG
+   is zero or less.
+4. Group the remaining entries by the species key.
+5. TOTAL_WEIGHT of a group is the sum of WEIGHT_KG of all entries in the group.
+6. BOAT_COUNT of a group is the number of different boat IDs in the group.
+7. The result has one row for each group. The rows are in ascending order of the
+   species key.
+8. If no entry remains, the result is empty.
+
+BEST_SPECIES:
+
+9. Build the groups with the rules 1 to 8.
+10. Return the species key of the group with the highest TOTAL_WEIGHT.
+11. If two groups have the same highest TOTAL_WEIGHT, return the species key that
+    is first in ascending order.
+12. If there is no group, return an empty value.
+
+# 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 create or change 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.
