A lot of this sprint was invisible to end users but will matter to everyone who's looked at a credential render and thought "this is a lot to scan." Today's post covers a full redesign of how Digital Product Passports display, two AI misbehavior problems (and how we fixed them), and one deliberate decision to leave something that looks like a bug alone.
Milestone 1 is complete: all five UNTP credential types are live in DPP Kit, with AI-assisted credential creation for Digital Product Passports and Digital Facility Records. Here's what shipped, the bugs that taught me things, and what's coming next — including selective disclosure by April.
The core flow — upload documents, let the AI agent extract claims, review and edit, issue a credential — was working. But there were enough rough edges in how state moved between the editor, the AI agent, and Directus that real usage was exposing real problems.
Sprint Update: Days 8-9 — AI Credentials, Stateless Verification, and a Launch-Blocking Bug We Almost Missed We're nine days into what I've been calling the epic sprint, and the last two days were a mix of genuinely exciting new capability and the kind of architectural reckoning that makes you grateful you caught it before launch. Here's what happened.
This post documents Day 7 of building DPP Kit in public, covering the development of an AI-assisted credential editor that lets users generate and refine UNTP-compliant credentials through a split-panel chat interface with per-field accept/reject controls. It also captures key architectural decisions — like shared context builders, prompt caching, and Tier 2 validation integration — that make the system efficient to scale across credential types.
Day 5 of building a UNTP compliant W3C Verifiable Credential Issuing and Management System. Today we tackled integrated Tier 2 testing into it's own module and also inline during credential editing and issuing.
Tales of Day 4, going from local development to a publicly accessible multi-tenant UNTP credential issuing platform
Building in public road map for a multi-tenant W3C Verifiable Credentials management platform to support UNTP practitioners. From empty directory to published to dppkit.io with build in Tier 2 testing in just a week.
