Summary

This proposal creates an open-source, Scala-native toolkit for upgrade-readiness qualification, version compatibility testing, and reproducible conformance reporting for Canton deployments and reference applications. It delivers shared reliability infrastructure that executes real scenarios, emits machine-readable and human-readable reports, and provides a practical foundation for safer change qualification across the Canton ecosystem.

Notes for Reviewers

This proposal is intentionally scoped as a narrow first wedge:

live environment qualification
scenario-driven conformance execution
structured report generation
extension path toward upgrade qualification

A working demo repository already exists at merged-one/canton-upgrade-conformance-kit-demo, demonstrating technical feasibility of the core scenario model and report generation.

Feedback is especially welcome on:

the first scenario families to prioritize
preferred reference targets for early integrations
expectations around upgrade qualification scope
desired format for certification-style outputs
