CounterStrike-1K Schema

This directory is the release-facing schema contract for CounterStrike-1K. It describes the public WebDataset sample members, Parquet indices, and derived match traces distributed with the Hugging Face release.

The schema boundary is intentional:

• Raw HLTV demo files are not redistributed.
• Steam IDs, XUIDs, account IDs, profile URLs, raw HLTV identifiers, raw demo paths, raw demo URLs, and player names are not valid public fields.
• Player references use pov_idx, an anonymized integer stable only within one match_id. It is not a dataset-global player identifier.
• Aggregate player counts may be reported in stats/, but public artifacts do not contain player names or stable cross-match player identifiers.
