}

Flat per-request record for optional JSONL emission. One JSON line per request is consumed by external analysis tools that want per-request granularity (TTFT vs. ISL scatter, worker-residency analysis, bypass classification, etc.).

Fields

request_id: Option<String>

Authored request identity from ReplaySpec. Legacy runtime inputs that only carry an internal UUID leave this unset.

play_id: Option<String>

session_id: Option<String>

Session identifier from the trace, when present. Mirrors AIPerf’s conversation_id field for the same purpose: bucket per-request records by multi-turn session. Placed first in the serialized output so each JSONL row leads with its session/turn identity, matching AIPerf’s profile_export.jsonl layout.

turn_index: Option<usize>

Zero-based turn index within session_id, when present.

metadata: Value

Authored provider-neutral metadata retained for correlation.

uuid: String

arrival_time_ms: f64

dispatched_at_ms: Option<f64>

first_admit_ms: Option<f64>

terminal_time_ms: f64

first_token_ms: Option<f64>

last_token_ms: Option<f64>

ttft_ms: Option<f64>

ttst_ms: Option<f64>

e2e_latency_ms: Option<f64>

itl_ms: Option<f64>

Inter-token latency for this request, in milliseconds. Matches AIPerf’s inter_token_latency field — one scalar per request.

input_length: usize

requested_output_length: usize

Number of output tokens requested by the workload trace.

output_length: usize

Number of output tokens actually emitted by the mock engine.

reused_input_tokens: usize

first_admission_g1_reused_input_tokens: Option<usize>

first_admission_host_reused_input_tokens: Option<usize>

prefill_worker_idx: Option<usize>

decode_worker_idx: Option<usize>

prefill_admit_ms: Option<f64>

source_held_ms: Option<f64>

destination_reserved_ms: Option<f64>

destination_activated_ms: Option<f64>

decode_admit_ms: Option<f64>

source_released_ms: Option<f64>

decode_reused_input_tokens: Option<usize>

prefill_route_overlap_tokens: Option<usize>

decode_route_overlap_tokens: Option<usize>

routing_history: Vec<PerRequestRoutingRecord>

admission_history: Vec<PerRequestAdmissionRecord>

admission_count: usize

readmission_count: usize

pressure_record_ordinals: Vec<u64>

terminal_status: ReplayTerminalStatus
