Knowledge-pipeline architecture
An accessible account of the 2024–2025 Jefferson Health Plans system: regulated plan materials transformed into checked, source-traceable knowledge for Outreach and Product.
Provenance
Based on Cole Lyons's firsthand account of the 2024–2025 Jefferson Health Plans implementation and supporting project research.
Version
Historical architecture v1.0; reviewed July 14, 2026.
The system in one view
Final plan information moved downstream from a regulated document cycle into a checked knowledge layer, a routed retrieval experience, and two operating teams. The source documents remained authoritative. Neither CMS nor actuaries certified the conversion or assistant, and the model never became the source of truth.
Historical system · 2024–2025
From final plan material to source-traceable answers
Upstream authority
Final EOC, ANOC, Medicare Summary of Benefits, and applicable ACA benefit-summary material, downstream of the regulated document cycle.
Begin with final materials
Final EOC, ANOC, Medicare Summary of Benefits, and applicable ACA benefit-summary material remained the upstream authority.
Structure the source
Plan material became structured SharePoint and Excel knowledge with product, plan-year, document, and section context.
Compare, resolve, and review
Python checked character content, counts, and position for every converted item. Discrepancies received manual review, followed by a complete visual review of every page across the included lines of business.
Route before retrieval
A Copilot Studio worktree narrowed the relevant product, plan, year, market, document, and topic before GPT-4o retrieval.
Meet staff where they worked
Teams was the primary interface. SharePoint and PowerApps provided alternative ways into the same operating model.
Cite the exact section
Answers required inline citations to exact SharePoint sections, with onward links to the original PDFs.
Fall back to searchable sources
When the assistant could not support an answer, staff could search SharePoint. There was no automatic live-agent handoff.
Support operating work
Medicare Stars Outreach and Product used the resulting knowledge system for plan-material questions and change work.
What made the architecture trustworthy
The difficult boundary sat between the final member-facing documents and the searchable knowledge layer. A successful text conversion was not enough. Character and position checks could expose missing, duplicated, or displaced content; manual discrepancy review could determine whether the problem belonged to the conversion or the source; and complete visual page review could catch structure that counts alone could not prove.
The worktree then constrained retrieval. It established context before GPT-4o searched, reducing the chance that similar plan names, years, or benefit language would be treated as interchangeable. Inline citations preserved the short path from an answer to an exact SharePoint section, then onward to the original PDF.
Scope and boundaries
| Boundary | What the historical system included | Limits |
|---|---|---|
| Corpus | 2024–2025 EOC, ANOC, Medicare Summary of Benefits, and applicable ACA benefit-summary material, with formulary context inside plan documents | A complete drug-level formulary or standalone Medicaid/CHIP corpus |
| Validation | Every-item Python character, count, and position comparison; manual discrepancy review; complete visual page review | CMS or actuarial certification of the conversion, knowledge layer, model, or assistant |
| Retrieval | Copilot Studio worktree routing before GPT-4o retrieval | A model that inferred every routing branch without constraints |
| Interfaces | Teams primary; SharePoint and PowerApps alternatives | A current-branded interface or claim of present operation |
| Traceability | Mandatory exact-section citations and onward links to original PDFs | An answer whose confidence replaced source evidence |
| Fallback | Searchable SharePoint for unsupported answers | Automatic live-agent handoff |
| Use | Medicare Stars Outreach and Product work | Adoption counts, causal outcomes, Star Ratings effects, or enterprise-wide use |
