S1 is the inspected archival version of the release. S2, S4, S5 and S6 were inspected in the browser during research. S3 was available through extraction, with blocked browser access; it is supporting evidence and the main conclusion does not depend on it. The populated ledger records passage locators, displayed dates, version identity and access limits.

The concluding release definition covers infrastructure, including IaaS and bare metal, and platforms hosted by third-party providers and delivered over the Internet. It does not establish every exclusion, gross/net treatment, currency-conversion rule or the full raw inputs and model.
