people wrote the code, at the speed people work.



A second agent, of equal capability to the coding agent, with a different objective. The coding agent’s job is to complete the work and ship it. Studio’s job is to confirm what shipped did what you intended
Shipping and confirming are different jobs with different objectives. A single system optimized for both ends up doing neither well. Splitting the job is the architecture, not a workaround.
You own the standard for what good means, which risks matter, and the call to ship. The agents handle the execution: writing the code, running the check, keeping the suite current.
Most AI testing tools write scripts and run them, so you read the result of a script against itself. Studio confirms the build against the running application. The proof is in what the software did.
