# @suaveplan/network-plugin-middleware - Priority-ordered middleware chain for the Suaveplan mesh: manager + logging, validation, transformation, metrics, throttling, security, i18n

## Summary

Priority-ordered middleware chain for the Suaveplan mesh. Inbound and outbound message flow each pass through the same five-band pipeline (CRITICAL → HIGH → NORMAL → LOW → BACKGROUND) with runtime add/remove/enable/disable. Ships seven concrete middlewares — `LoggingMiddleware`, `ValidationMiddleware` (Zod, strict / lenient), `TransformationMiddleware`, `MetricsMiddleware` (size + processing time), `ThrottlingMiddleware` (`@suaveplan/rate-limiter` token-bucket; global / per-peer / per-type), `SecurityMiddleware` (injectable sign / verify hooks per tier policy), and `I18nMiddleware` (locale headers, RTL marker, UTC timestamp normalisation) — wrapped in a single `MiddlewarePlugin` that satisfies the `NetworkPlugin` lifecycle.
