Analysis-Ready Live Match Feature Snapshots for Professional Dota 2 (2023-2026): 92,379 Matches and 1,027,237 Snapshots

This analysis-ready release contains scheduled live-match snapshots from 92,379 professional Dota 2 matches played between 4 February 2023 and 18 March 2026 across Patches 7.32-7.40. The dataset contains 1,027,237 snapshots at 17 observation minutes: 10, 12, 15, 17, 20, 21, 22, 23, 25, 27, 30, 32, 35, 38, 40, 42, and 45. Its 48 audited columns cover match identifiers, match outcome, hero drafts, kills, net-worth distribution, and cumulative tracked-purchase aggregates. Version 2 corrects the unique-match metadata reported in version 1 and removes 49 duplicate (match_id, minute) rows, 328 defective historical item-propensity columns, and eight outcome-derived item boost/counter variables whose temporal provenance was not established. The accompanying Experiment 211 reproducibility package contains the frozen temporal fold map, analysis and verification scripts, 20 saved out-of-sample prediction artifacts, statistical summaries, figures, data manifests, and verification reports. The source telemetry was obtained through the OpenDota API.
