The newest PDF adds a two-page appendix describing how learners badge into the Hwaseong aisle, what photos are prohibited on the floor, and how VPN rotations line up with lab windows. We keep language blunt so security teams can paste sections into their own runbooks without rewrites.
A second section lists the Spark versions pinned for April–June intakes, including the Iceberg catalog build we certify against. If your employer blocks direct downloads, request the GPG-signed bundle via the form on the program mesh page.
Finally, we document how anonymized skew traces are scrubbed before they ever leave the perimeter—important for legal teams reviewing the memo alongside finance.
Edits ship with semver-style tags in the footer of each PDF so you can prove which revision was circulated during procurement.
