Coding agents are opening PRs faster than anyone can review them. Manish Kapur (Sonar) and Addy Osmani (Anthropic) discuss "light" vs. "dark" software factories, how Anthropic scaled from about 2,500 to 30,000 merged changes a day with Claude doing first-pass review backed by real verification evidence, new data from Sonar's State of Code survey, and why every loop in the factory needs independent, multi-layered verification. They close with a lightning round on labeling agent-written PRs and when it's safe to merge.
