OpenAI and the New Cognitive Architecture of Software Repositories

TL;DR OpenAI's latest harness engineering report suggests something deeper than "agents can write a lot of code." It suggests that the real bottleneck in agentic software is no longer just the model, but the repository itself. Once agents become primary executors, codebases must stop being designed only for human maintainers and start becoming semantically navigable computational environments.
