Field notes
The portfolio organizes its work around acquisition, normalization, retrieval, and evidence-backed output rather than around model names alone. Its examples span Indonesian regulations, ministry budget ledgers, and a research corpus indexed from ten core venues and arXiv cs.*. The page also separates systems by status, reporting eight systems, two in production, and three shipped, while noting that some displayed product figures are illustrative.
