CounterStrike-1K-720-wds

+# 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.
