Oracle Writer Instructions

You are given rows from data/oracle_seed.jsonl.

For each row:

1. Read messages as the exact chat input. prompt is only a flattened fallback for non-chat tooling.
2. Produce an optimized C++20 program that preserves exactly the same stdin/stdout behavior as source_code.
3. Return the original input messages unchanged, then append exactly one assistant message with:
   • one <reasoning>...</reasoning> block;
   • one fenced cpp code block;
   • no extra text before, between, or after those two parts.
4. Compile the generated program with the row's compile.command.
5. Run all visible tests from visible_tests.
6. Fill the verification object truthfully.

Do not return partial-credit rows for training. If a solution does not compile or does not pass tests, mark it as failed and do not call it oracle data.

The expected output JSONL shape is shown in data/oracle_return_example.jsonl.
