  "summary": "Design review approved. PricingService.seedVariantPrice (pricing owns pricing_variant_prices) is injected into CreateProductVariant via the pricing public index (R1-clean, identical to the cart→pricing cross-module write pattern). A single constructor covers all 3 variant-creation call sites. build-app hoists the pricing const above catalog registration — a pure construction reorder with no side effects. Seed is best-effort so variant creation never regresses.",
  "checks": [
    {"item": "catalog→pricing cross-module import goes through public index (R1)", "ok": true, "evidence": "import type { PricingServicePort } from '../../pricing/index.js' in variant-use-cases.ts and catalog.routes.ts"},
    {"item": "single CreateProductVariant constructor covers all call sites", "ok": true, "evidence": "new CreateProductVariant(repository, variants, deps.pricing) — used by POST /products (autovariant), GET /products/:id/variants (lazy), POST /products/:id/variants"},
    {"item": "build-app pricing hoist does not break pricing/cart routes", "ok": true, "evidence": "createPricingService(deps.pool) moved above registerCatalogRoutes; registerPricingRoutes and registerCartRoutes unchanged and still reference the same pricing instance"},
