Artifact vintage: the product page and shipped documentation state the exact coverage, row counts and known limitations. A purchase delivers the advertised frozen artifact; no future refresh is promised unless the checkout terms explicitly say so.
A competition season has not been verified for this archive. This is not a complete-season archive.
UTC timestamps retain their recorded precision; dates alone identify UTC days. Vintage, observation and sports event times are separate. Capture time does not establish exchange quote freshness.
Sports event starts: start unknown → end unknown. Event dates are not inferred from these quote capture windows.
Polymarket combo fills are public on-chain events: anyone can re-read them from Polygon. Kalshi publishes per-market trade history, so complete prints for any listed combo can be fetched from Kalshi directly. What this archive adds is the decoding and joining: each Polymarket combo's decoded legs, market names and on-chain outcome; Kalshi's combo definitions with leg labels, combo and leg results, and the book snapshot our recorder took when it registered each combo, in one schema with a derived coverage map and a list of every known gap (gaps.csv).
Dated snapshot: 41,203 Polymarket combo fills · 10,051 Polymarket combos · 60,011 Kalshi combo definitions · 80,609 sampled Kalshi combo prints · 709,554 total rows · Kalshi trade prints are a small sample: about 2.0% of all Kalshi combo trades Aug 6-Oct 4, 2026, measured against Kalshi's own history · 2026-09-13 through 2026-09-14 · artifact vintage 2026-09-14; separate from observation times
