Explanation
Issue [
#1253] coding requirements are met. Fast runs time successful response, v1 embedding, and v2 judge calls. The rollup stores stage averages, call counts, and a call-weighted overall average. Failed, missing, guardrail-excluded, and untimed rows do not count. The nullable field is persisted and exposed on the existing run endpoints. Batch runs remain untimed.attach_latencylogs failures without blocking completion. Tests cover timing, rollups, persistence, endpoint output, exclusions, and failure isolation.

Explanation
The changes stay within issue [
#1253]. The migration, model updates, fast-path timing, rollup helper, tests, and documentation support the latency summary. The changes do not add batch latency, webhook latency, p95, maximum, or per-question latency. The completion webhook tests confirm that latency remains excluded.

Single start_timer/elapsed_ms seam replaces the perf_counter expression copy-pasted across fast.py and judge.py; clock-mock tests patch one module. Also sort the latency import, type stage entries, match cost's no-default on EvaluationRunPublic, and split latency semantics into its own wiki bullet.

Two tests pinned the overall average to 0.05 ms of unrounded stage sums, a precision no consumer reads. Call-weighting and partial re-attach stay covered by the remaining rollup tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick winClear stale latency for explicitly processed stages.
_stage_entryreturnsNonewhen all rows fail or lacklatency_ms.attach_latencythen returns without clearing the existing JSONB value. This can preserve stale counts on a Stage 3 retry._attach_stage_costsalso converts an empty processed list toNone, which means “preserve this stage.” The judge path skipsattach_latencywhen every judge call fails.Keep omitted stages distinct from processed empty stages. Clear an explicitly processed stage when it has no timed calls, while preserving stages that were not supplied.

Closes #1253
Summary
Fast evaluation runs already report the cost of their OpenAI calls. This PR also reports how long those calls took. Each run gets a
latencyfield with the average call time per stage and one overall average.Only successful calls are timed. Failed rows, rows that hit a missing question, and guardrail
blocked/rephrasedrows are excluded. The overall average is weighted by call count, not a mean of the stage means.The field appears on the existing
GET /api/v1/evaluationsandGET /api/v1/evaluations/{id}endpoints. It is not sent in the completion webhook payload.Example
latencyfor a v2 run:Evidence
Before:
EvaluationRunPublichas nolatencyfield, and nothing in the fast pipeline records how long calls take.After: the field is exposed on the run endpoints:
After (pipeline end-to-end):

test_fast_llm_call.py, clock patched at 1.5 s):After (scope stays narrow):
result.latency is None(test_processing.py).latency(test_completed_run_delivers_slim_success_payload).Merge Danger
Door: two-way
Migration 086 only adds a nullable JSONB column. Rolling back runs
drop_column, which loses any latency values recorded since deploy. Nothing else depends on that data.Blast Radius: small
latencykey, which is additive. It isnullfor batch, STT/TTS and pre-deploy runs.latency_mskey per row. They are now a superset of the batch path's shape.attach_latencycatches every error and only logs a warning, so it cannot block a run from completing.call_countcan be lower than the number of successful rows for runs redelivered across the deploy, because pre-deploy units have nolatency_ms.Checklist

Issue
Closes #1253
Summary
evaluation runs already report the total cost of the OpenAI calls they make. Until now there was no way to see how fast those calls were. This PR adds a latency summary next to cost on every fast evaluation run, so we can see the average time an OpenAI call took, broken down by step.
What's new
latencyfield. It shows the average call time in milliseconds and the number of calls, for each step of the run, plus one overall average:GET /api/v1/evaluationsandGET /api/v1/evaluations/{id}). v2 runs are read through these same endpoints. No new endpoint was added.Example for a v2 run:
