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 August 26, 2026. 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.

- 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.
- Uncertainty
- This is a selected public chronology, not a complete event log. Reconstructed timestamps may contain small error, and a publication date does not establish when analysis completed.
- What this figure does not prove
- Temporal proximity does not prove causation, coordination, completeness, legal liability, or the accuracy of another lane's claims.
