Struct ErrorSample 

pub struct ErrorSample {
    pub status: u16,
    pub server_header: Option<String>,
    pub body_excerpt: String,
}

One captured non-2xx response — used to surface who sent the error (mockforge? a proxy in front?) and why. Critical for diagnosing “I see 503 from the bench but the server log shows 200” — almost always an upstream proxy timing out on a slow chunked upload.

Fields

status: u16

server_header: Option<String>

Server response header, when present. Often reveals the proxy: nginx/1.21.0, cloudflare, envoy, awselb/2.0, etc.

body_excerpt: String

First N bytes of the response body, lossy-UTF8’d. Trimmed.
