+"""
+Generate a report of actual revert commits in pytorch/pytorch over a given period
+and annotate whether each has a matching non-dry-run autorevert decision recorded
+by misc.autorevert_events_v2.
+
+Columns:
+- revert_time (UTC)
+- original_sha (the commit being reverted)
+- category (from -c flag in the bot command comment, else from message, else 'uncategorized')
+- reason (short reason parsed from the revert commit message, if present)
+- author (GitHub login from the bot command 'on behalf of' attribution in the message)
+- comment_url (link to the bot command comment if present)
+- has_autorevert (yes/no) — whether misc.autorevert_events_v2 recorded a revert for original_sha
+
+Usage examples:
+- python -m pytorch_auto_revert.testers.actual_reverts_report --start "2025-09-16 22:18:51" --end "2025-09-24 00:00:00"
+- python -m pytorch_auto_revert.testers.actual_reverts_report --start "2025-09-16 22:18:51" --format csv > reverts.csv
+
+This script uses the ClickHouse client configuration from environment variables
+as done by the project entrypoint (CLICKHOUSE_HOST, CLICKHOUSE_PORT, CLICKHOUSE_USERNAME,
+CLICKHOUSE_PASSWORD, CLICKHOUSE_DATABASE). You may also use a .env file.
