Struct KernelObservability 

pub struct KernelObservability {
    pub reasoning_timeline: Option<Vec<String>>,
    pub lease_graph: Option<Vec<(String, String)>>,
    pub replay_cost: Option<u64>,
    pub interrupt_latency_ms: Option<u64>,
}

Available on crate feature execution-server only.

Runtime-derived kernel observability / telemetry.

Fields are optional so responses can remain backward compatible when a given execution path does not have enough source data.

Fields

reasoning_timeline: Option<Vec<String>>

Optional reasoning or decision timeline (e.g. scheduler steps).

lease_graph: Option<Vec<(String, String)>>

Optional lease/ownership snapshot (e.g. attempt → worker).

replay_cost: Option<u64>

Optional replay cost hint (e.g. event count or duration).

interrupt_latency_ms: Option<u64>

Optional interrupt handling latency (e.g. ms).
