Struct SpanFields 

pub struct SpanFields {
    pub component_ref: String,
    pub digest: String,
    pub tool: String,
    pub args_sha256: String,
    pub args_json: Option<String>,
    pub session_id: Option<String>,
    pub transport: String,
    pub outcome: String,
    pub duration_ms: u64,
    pub request_id: String,
}

The envelope-span fields the layer captures at span open and completes at span close.

Fields

component_ref: String

digest: String

tool: String

args_sha256: String

args_json: Option<String>

Full arguments, present only when --audit-args was set for this run. render_rollup shows this instead of the digest when present — the digest is still captured above, just not the thing printed.

session_id: Option<String>

transport: String

outcome: String

Defaults to "incomplete", never empty: a span that closes without finish_tool_call ever recording an outcome (dropped early, never entered) must not render as if the call had actually completed.

duration_ms: u64

request_id: String

std:request-id, or a host-generated id. Rendered truncated and escaped — it is the only way an operator can join one audit line back to a client log line.
