2 * /info + /ready contract tests for apps/api — pin the readiness gate
3 * logic so the matrix of (configured? × reachable?) stays testable
4 * without standing up postgres / redis. Build-identity resolution is
5 * exercised by packages/shared/src/build-identity.test.ts since the
6 * resolver lives there now.
