Single-file HTML pages published as Claude Artifacts. Two projects share one engine (JSON model in the page, generated tabs, inspector, BPMN 2.0 export, automated checks).
| Project | Purpose | Version | Artifact | Source |
|---|---|---|---|---|
| Tallgrass Data Journey | Matillion presales live demo: SQL Server EDW to Databricks, AI readiness, Maia (illustrative) | v3 | https://claude.ai/artifact/E9qAq2xH861z7dLuoeTGhv | data-journey/ |
| Master Data Atlas | Learning project: master data reference model | v5 | https://claude.ai/artifact/RQwdyLoD7o17zoTmM1Cx9n | reference-model/ |
Both artifacts are private to the owner until shared from the page’s Share menu. All companies and figures are fictional.

For each page: data cross-references resolve, the script parses, every tab (and talk-track step) renders at desktop
and phone width without errors, and each BPMN export is valid. Screenshots go to tests/out/<page>/.
