# CI performance qualification for the constant-tag concat experiment.
#
# This direct-SST fixture fixes file, row-group, and label layout independently
# of ingestion and SQL flush behavior; it does not claim to reproduce a
# SQL-flush baseline. With timestamp-major generation, every series occurs at
# every scrape timestamp and each series spans all 32 non-overlapping SSTs,
# exercising cross-file reads for the multi-evaluation queries.
