Each asyncio.to_thread hop had to win the GIL from the uploader thread several times, so under load a log() call took up to 87 ms. The load test drops its expected failure for 1,000 episodes. Its fake Traces endpoint gzips at the SDK's level and counts lines under a lock, since the client now sends several requests at once.

A production RL run's episodes are larger and vary a lot: median 6.4 MB, p90 17 MB, p99 35 MB, uncompressed. Each episode now draws its size from a lognormal through that median and p90, which also matches the run's mean and p99. Sizes are capped at 60 MB, under Prime Traces' 64 MiB line limit. The episodes share 24 traces at log-spaced sizes, so the test's memory stays small. A thousand episodes is now about 8 GB of JSON, close to one production step of 1,024 samples. The file monitor's check counted only the first trace chunk, read whole. It now streams every chunk, since 8 GB spans two.

It now writes Episode.to_json(), which encodes one node at a time. The stream line is byte for byte the same. The index row came from the same record. It now comes from index_record, which dumps everything but the nodes' payloads, a trace at a time. ChunkedJsonl.append takes a line in parts, so the newline is written without copying a long line.
