Extreme Harness Engineering for Token Billionaires: 1M LOC, 0% Human Code, 0% Human Review

OpenAI's Frontier team built a 1M-line Electron app with zero human-authored code: the competitive advantage wasn't the model, it was six skills encoding what "good" looks like as text. The real shift here isn't AI writing code; it's AI inheriting engineering culture. Ghost libraries (distributing specs instead of code) and Symphony (an Elixir orchestrator the model chose for its process supervision primitives) point to a future where the scarce resource is institutional knowledge distillation, not developer headcount.
