Why the history starts here
Zelvian Tech has earlier project and product work, but this public changelog intentionally starts when structured public-proof tracking was introduced. Earlier dates, versions and claims are not reconstructed without reliable records.
Product release notes
Product-specific changelogs will be published only when a release history can be safely disclosed and tied to verified product versions. Confidential client release history remains private.
