Cloudflare now documents 90-day retention after completion for Workers Builds and their logs. After that period, the build record and logs are removed. Versions and deployments produced by the build remain in version history and available for rollback. Logs needed longer can be downloaded through the build-log API.

The limits table specifies the same retention period for free and paid plans. Reference: https://developers.cloudflare.com/workers/ci-cd/builds/limits-and-pricing/
AudioSlave analysis: Restoring a website version and explaining how it was built are different capabilities. A useful deployment record connects the build identifier, deployment version, completion time, retained logs and acceptance results. This is a proposed evidence method, not a claim that the logs establish complete reproducibility or that AudioSlave has implemented an archive.
