TTL, initial window and MSS come from the raw SYN packet -- the one layer a proxy fleet can't easily disguise, since it describes the kernel that opened the socket. Best-effort: requires a capture covering this connection's timestamp.

img_avif | Image format: AVIF image -- tests whether the fetcher can decode it. | fetched | 1 |
img_jpeg | Image format: JPEG control image; the embedded number proves the bytes were decoded. | fetched | 1 |

img_webp | Image format: WebP image -- tests whether the fetcher can decode it. | fetched | 1 |
Response headers are what the handler explicitly set. Content-Length and Date are added by Go's HTTP stack directly to the wire afterward and never pass back through the header map, so they don't appear here -- see Bytes for the actual byte count.

TTL, initial window and MSS come from the raw SYN packet -- the one layer a proxy fleet can't easily disguise, since it describes the kernel that opened the socket. Best-effort: requires a capture covering this connection's timestamp.

Response headers are what the handler explicitly set. Content-Length and Date are added by Go's HTTP stack directly to the wire afterward and never pass back through the header map, so they don't appear here -- see Bytes for the actual byte count.
