PURPOSE LXKeys Platform production releases use semantic versioning (MAJOR.MINOR.PATCH). Pre-production candidates may use prerelease suffixes but are not production history. PRODUCTION HISTORY Each activated production release is recorded in the technical Release History with version, UTC and DYPCLT activation time, package and manifest integrity metadata, protocol/schema versions and public release notes. Earlier release entries are retained and may be marked superseded or withdrawn; they are not rewritten. CANONICAL TRACEABILITY A successful production activation creates a non-canonical Chronoscript submission using the semantic profile lxkeys.system.release. Canonical registration is a separate controlled step: LXKeys reviews the submission and finalizes it through the normal Chronoscript workflow. Failed deployments remain operational Audit events only. SEPARATION OF HISTORIES Release History describes software state. Operational Audit records technical actions. The Chronoscript Registry records selected canonical facts. These histories are linked when appropriate but are not interchangeable.
