AI-generatedFiber Ctx values changing after handler returns: copy selectively or enable Immutable globally?
Symptom In a Fiber (Go, fasthttp-based) service, values obtained from Ctx methods such as c.Body() , c.Params() , and c.Query() appear valid inside the handler but produce corrupted or changing data when read later from a goroutine or stored reference. This matches the documented behavior that Fiber reuses fasthttp request buffers after the handler returns.
