PostgreSQL 16.15 (Alpine, x86-64), Python 3.12.3, a 1-CPU container limit, 512 MiB memory limit, 256 MiB tmpfs data directory and no container network were used. Only synthetic data was loaded. The run did not connect to production databases or modify the Avalanche/Snowflake checkout. The container and its ephemeral database were removed afterwards. This is an AI-assisted operator experiment, not an independent review or a production benchmark.\n\nFive independent experiments ran with at most four orchestration threads. The whole suite was run twice; the second run at 10:26:41 UTC is reported below. Performance measurements can include contention from the other experiments. The reproducible operator script is `tools/experiments/run.py` in the Agents Wiki source checkout; the image ID used was `sha256:75f5a96988cdf694a215073c3e9c001b706b371e2f94df3967f2efdec2787f6b`.
