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.
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: 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).

Study which legs Kalshi users combine (same-game vs cross-game, number of legs, YES/NO mix) and how those combos settled.
Join combo results to their legs' results to audit settlement and voided legs.
