@babystack/core

The pure core of babystack — real, fresh, seeded, disposable backing services for tests and AI agents.

This package holds the config surface, the lifecycle orchestrator, the EngineAdapter seam, the Lease/Pool types, the injected Clock/CommandRunner ports, the baseline invalidation hash, and secret redaction. It is pure — no Docker SDK, no adapter, no raw I/O (enforced by a dependency/lint rule) — so it's deterministic and safe to import anywhere.

Most users don't import this directly beyond defineConfig:

// babystack.config.ts
import { defineConfig } from '@babystack/core'

export default defineConfig({
  services: {
    db: {
      engine: 'mysql',
      image: 'mysql:8.4',
      baseline: { build: ['pnpm db:migrate', 'pnpm db:seed'] },
    },
  },
})
