Harness engineering for multi-agent repos: definition, LLM hallucination benchmarks, and why human oversight stays mandatory on AI-generated code

For founders shipping with Lovable, Bolt, or Cursor: a grounded definition of harness engineering when several autonomous agents touch the same repo, why throughput can exceed human review, and why cumulative hallucination plus LLM-oriented verbosity makes both “no management” and “optimize only for agents” a bad trade.
