Class: CorrelationMiddleware

Defined in: packages/common/src/nest/correlation.middleware.ts:20

Opens a correlation context for each HTTP request and echoes the id in the response header, so success carries it as well as failure (chapter 30).

Adopts a well-formed inbound x-correlation-id, otherwise mints one. Works on the raw Node request, so it is adapter-neutral (Fastify's middleware layer and Express alike). Register with consumer.apply(CorrelationMiddleware).forRoutes('*'). Does nothing about tenantId: that is known only after authentication, and the caller adds it with enrichContext.
