Incident, disclosure, review, legal process, and vendor response

A source-labeled chronology separates OpenAI's company report, independent reconstruction, Hugging Face host telemetry, legal process, and vendor remediation from May 8 through the subpoena's September 14 response deadline. July 5 is an OpenAI-attributed alert and response event.

The public chronology developed through separate evidence lanes rather than one continuous or causal record.

Incident, disclosure, review, legal process, and vendor response A source-labeled chronology separates OpenAI's company report, independent reconstruction, Hugging Face host telemetry, legal process, and vendor remediation from May 8 through the subpoena's September 14 response deadline. July 5 is an OpenAI-attributed alert and response event. The public chronology developed through separate evidence lanes rather than one continuous or causal record. Selected public chronology Grouped by date. Evidence lanes and states stay separate. No causal connectors are drawn.

Transformations
  • Do not draw causal connectors or infer events on unshown dates.
  • Preserve source-supplied date precision and prefix every event with its evidence lane.
  • Render July 5 as an OpenAI-attributed alert and response event, not as a neutral marker.
  • Render September 14 as a commanded response deadline, not evidence that no private response or procedural change has occurred.
Uncertainty
This is a selected public chronology, not a complete event log. Reconstructed timestamps may contain small error, a publication date does not establish when analysis completed, and the public record through August 27 does not disclose nonpublic procedural activity.
What this figure does not prove
Temporal proximity does not prove causation, coordination, completeness, legal liability, or the accuracy of another lane's claims.
