Productised work we built and run for real customers — proof of the doctrine, not slideware. Deterministic where it counts, local by default, human-approved at the edges.
The same pattern — high-stakes, credential-bearing, deterministic, human-gated — extends naturally to adjacent domains: other jurisdictions' filings, invoicing and AR/AP, and payroll. Want one of these for your setup, or a different system entirely? That's what the build studio is for.
