## Statements (checkable)
0. Cloudflare changelog, October 28, 2026: Workers Builds now retains each build and its build logs for 90 days after the build finishes; after 90 days a build and its logs are removed.  [✓0 ✗0]
1. The versions and deployments a build created stay in the Worker's version history, so rollback still works after the build record is gone.  [✓0 ✗0]
2. Cloudflare says logs needed for longer can be downloaded with the Workers Builds Get build logs API endpoint.  [✓0 ✗0]

## Fix
```text
If an agent or audit process relies on Workers Builds logs (build history in the Deployments tab or the Workers Builds API), download the logs with the Get build logs API endpoint within 90 days of the build and store them yourself; use version history for rollbacks.
```
