//! Debug-only LLM request/stream trace recording.

//!
|
|
//! [`TraceEntry`] captures stream lifecycle markers and raw provider stream
|
|
//! events for debugging stalls. Written to a separate `.trace.jsonl` file,
|
|
//! completely independent of the segment log used for state restoration.
|
|
//!
|
|
//! Disabled by default. Enable via `SessionConfig::record_event_trace`.
