Accumulated query cost and runtime

Step sums of accepted active observations; ClickHouse batches use their accepted Snowflake reference-row coordinates, with original observations retained in the source. No query interpolation or rematching. Recorded benchmark rates. Query costs are normalized allocations. BigQuery uses Capacity pricing. Storage, discounts, free tiers, idle/minimum billing and standing fallback excluded. Each result > 5 seconds priced in full at Gen2 Small; all others Interactive Small. No additional primary charge. Compilation included. Fresh-data-path cost follows the explorer's proportional allocation of complete-ingest cost by row progress. On logarithmic axes, zero values remain in readouts and have no plotted position.
