How v2 was built

  1. 1

    Architect writes typed contracts and config.

  2. 2

    Four Grok agents build core, AI, renderer, and the app shell in parallel against those contracts.

  3. 3

    Architect integrates the modules.

  4. 4

    Verify with typecheck, 90 tests, and Prettier, then ship.
