BDB × GPT-6 Astra

What is BDB × GPT-6 Astra?

GPT-6 Astra analyzes a bounded synthetic repository, finds a genuine concurrency defect, and proposes an exact two-file fix — but it cannot execute it. A human approves one SHA-256 fingerprint. BDB then verifies the approved bytes, materializes only that change, and runs fixed test + build checks in an isolated container with no network or secrets. The result is published as sanitized, inspectable proof.
