Board deck from tabular data
What the substrate produces A tabular data artifact, a data fidelity report, a cleaned dataset, an analysis brief, a deliverable plan, and a rendered downloadable presentation. A supervisor pause exists before the manager-visible deliverable is generated.
Governance boundary The v1 output is a downloadable deck artifact. External delivery to board portals, mailing lists, or shared drives is outside the current proof boundary.
Why this proves the claim The substrate handles work that begins with messy structured input and ends in an executive-ready artifact — turning data into a deliverable, not just text into more text.
