mir-backend-go-fiber

Make It Right (Fiber module). Fiber web framework reliability augmentation for Go backends. Use alongside mir-backend and mir-backend-go when the target stack is Fiber — adds the mechanical footguns the runtime-agnostic tiers deliberately omit: fiber.Ctx and all its values (Body, Params, Headers) are pooled and reused after the handler returns (retaining them causes data corruption across requests), fasthttp incompatibility with net/http middleware and ecosystem, the Immutable setting that controls whether returned strings reference reused buffers, and graceful shutdown via app.ShutdownWithContext. TRIGGER only when the Go backend uses the Fiber framework — building, reviewing, or debugging a Fiber handler, middleware, or route. Always loads TOGETHER WITH mir-backend (generic gates) and mir-backend-go (Go runtime concerns: goroutine leaks, context propagation, data races, channel rules, typed-nil, defer-in-loop, slice aliasing, error discipline, WaitGroup); this module only adds Fiber library mechanics. SKIP for Gin, Echo, chi, stdlib net/http, or any non-Fiber stack, and for non-Go runtimes.
