Start with source/internal/net/serve.go:254 and trace the request through source/internal/net/request.go, source/internal/stream/util.go, source/server/common/proxy.go, and source/server/handles/down.go. Reproduce a Quark JS download or preview using the reported /d or /p paths, then verify that the complete response is delivered without the EOF, gzip panic, or corrupted content.
