A landmark day for platform observability and data pipeline reliability. We shipped a fully wired Jobs monitoring page that surfaces all 13+ tracked job types, broke through a major ETL performance ceiling on the SynPUF dataset (17 hours → 14 minutes for drug_era builds), and closed out a cohort generation audit that uncovered eight discrete bugs across the SQL builders, API layer, and frontend.
A massive day on the ingestion front — 87 commits landed in Parthenon today, almost entirely focused on building out a brand-new end-to-end data ingestion pipeline. We now have a fully wired system for creating ingestion projects, uploading raw files, staging them into a schema-isolated PostgreSQL environment, and handing off to Aqueduct for ETL. This has been a long time coming.
A massive day on Parthenon with 193 commits landing across the platform. The headlining work: a near-complete publication/manuscript workflow that takes study analyses all the way to a formatted, auto-numbered document preview, plus a long-overdue rename of the R Analytics Runtime to Darkstar — the name it's been running under in Docker all along.
Today was one of those satisfying days where two major workstreams converged: we pushed the Ares data quality module from skeleton to a fully featured analytics suite with four distinct intelligence phases, and we permanently fixed a cluster of compounding bugs that had been making Achilles characterization runs fragile on large real-world datasets. Both efforts move Parthenon meaningfully closer to being a production-grade OHDSI research platform.
After months of a perpetually red CI pipeline, today marks a turning point for Parthenon: 92 commits, a full-spectrum codebase review, a complete AtlanticHealth patient synthesis pipeline, and — most satisfying of all — every CI job green. Here's how we got there.
A big architectural day on Parthenon: we shipped the new Workbench launcher experience and drafted the formal plan to collapse our multi-database mess into a single, schema-isolated parthenon database. A noticeably cleaner codebase on the other side.
A massive 116-commit push today centered almost entirely on maturing the Evidence Investigation workbench — from retiring the old FinnGen UI to hardening the investigation experience with proper navigation, KPI metrics, URL-synced state, and ARIA accessibility. We also landed multi-dataset support in Morpheus and set the stage for one of the most requested features on the roadmap: volcano plots powered by the newly-renamed Darkstar R runtime.
A big day on the quality and resilience front: 34 commits landed in Parthenon focused on a comprehensive codebase health audit, a major expansion of our Playwright E2E test suite, and a fork of the StudyAgent submodule. No flashy new features today — instead, we did the unglamorous but essential work of making sure what we've already built actually works, is safe to change, and won't silently break in production.
Today marked a significant architectural milestone for Abby, Parthenon's AI research assistant: the completion of Phase 1 of the Abby 2.0 memory overhaul. Eighty-six commits landed today, all focused on one goal — giving Abby a durable, queryable memory backed by PostgreSQL rather than ChromaDB, and surfacing user research context directly in the chat interface.
A productive Sunday on the Parthenon platform — 70 commits landed today covering four distinct themes: hardening the real-time Commons presence system, fixing a persistent CSRF authentication bug, overhauling the Grafana observability stack, and significantly expanding the medical knowledge base powering Abby, our AI research assistant.
