# 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.
