 - Use @bytelyst/* shared packages instead of reimplementing common infrastructure
 - Fastify modules follow types.ts → repository.ts → routes.ts
 - Use req.log / app.log — never console.log
-- Every Cosmos document MUST include productId: "bytelyst-notes"
+- Every Cosmos document MUST include productId: "notelett"
 - Keep docs aligned with implementation as the repo evolves from scaffold to product
-- Include `productId: "bytelyst-notes"` in every Cosmos DB document
+- Include `productId: "notelett"` in every Cosmos DB document
 - Use `type(scope): description` commit message format
 - Fix source code, not tests (unless the test itself is wrong)
