The Query Assistant received a ground-up redesign today — from a single 1,700-line monolith into a clean tabbed interface with two focused views, a live SQL execution modal with real-time PostgreSQL status feedback, and Solr-powered concept search built into every parameter input. This post walks through the architecture decisions, the UX patterns, and the production hardening that happened in rapid succession.

A big day on the Parthenon platform with two distinct workstreams landing in parallel: a fully-featured emoji reaction system for the collaborative messaging layer, and a comprehensive 136-test import suite designed to stress-test every data ingestion pathway the platform supports — including some deliberately nasty adversarial inputs.

Today was a focused, high-output session centered entirely on one major architectural shift: evolving the GIS Explorer from a hardcoded COVID-19 dashboard into a fully generalized spatial analytics tool capable of visualizing any condition in the OMOP CDM. Eighteen commits across the full stack — Python AI service, Laravel backend, and React frontend — tell the story of a component suite that went from COVID-specific to condition-agnostic in a single day.

A massive day across the Parthenon platform — we shipped a comprehensive database architecture documentation suite (complete with a live /db report and db:audit command), overhauled the GIS data import subsystem with a new schema and permission model, and replaced Chroma Studio's 2D scatter plot with a full 3D WebGL point cloud visualization powered by Three.js and a server-side PCA→UMAP projection pipeline.

A massive day across the Acumenus suite — 60 commits touching six repositories. The throughlines: a platform-wide push to standardize authentication using the MediCosts pattern, TypeScript migrations gaining serious momentum in multiple apps, and meaningful OHDSI clinical data work in Parthenon including surfacing 52.6 million clinical notes through a new Patient Profile tab.
