Struct ObservabilityContext 

pub struct ObservabilityContext {
    pub traceparent: Option<String>,
    pub session_id: Option<String>,
    pub name: Option<String>,
    pub tags: Vec<String>,
    pub metadata: BTreeMap<String, String>,
}

Vendor-neutral observability context carried on an LLMRequest.

The kernel treats this as opaque data — it never parses or forwards the values. Observability middleware consumes it:

• traceparent lets an adapter attach the generation under a trace the caller already opened (W3C trace-context format, matching the standard traceparent header, so callers inside an OpenTelemetry context can extract and pass it directly).
• session_id groups related calls per execution unit rather than per client.
• name overrides the observation name (verb-first, low-cardinality, model-free — backends index and filter by name).
• tags/metadata ride along for backend-side filtering.

Fields

traceparent: Option<String>

W3C trace context of the parent span (traceparent header format).

session_id: Option<String>

Session id grouping related calls in observability backends.

name: Option<String>

Observation name override (verb-first, low-cardinality, model-free).

tags: Vec<String>

Tags attached to the trace in observability backends.

metadata: BTreeMap<String, String>

Free-form string metadata forwarded to observability backends.
