The official write-up says the company built its own source-control system, <strong>Scion</strong>, and fully migrated its monorepo off git in about five months. In the same window it also shipped a code-review surface called <strong>Antique</strong>, code search, a source-code permissions model, and tooling for landing large volumes of already-reviewed code. This piece focuses on Scion. The team behind Scion, Antique, and related systems is about seven people.</p>
