Forks ImpossibleBench's LiveCodeBench solver rather than passing instruction_prompt=, which injects text into the system message, the user message and every failure message. The scratch line now appears once, in the system message, verified by the mockllm smoke run. test_byte_match.py reads ImpossibleBench's expected_test construction out of its source with ast and re-executes it, so our test.py is checked against theirs rather than a copy. Confirmed to fail on a one-character upstream change. Without this, drift flags every sample as test-modified, resets it, and destroys the cheat measurement silently. The event adapter fixes a bug carried over from messageboard: relation() left absolute paths absolute, so `cat /workspace/scratch/notes.md` classified as outside the directory. Every absolute-path touch would have scored as a miss. The checks are new rather than reused. The old ones score not-applicable when the prompt names the directory, which ours does by design, and discard reads after the first write. Both would undercount here. The decisions are kept, the code is not. Claude-Session: https://claude.ai/code/session_01Cq98H7sNoSJdL3W98f18bu
