# Sprint 6 Completion Report — Automated Research and Population Engine

## Implemented

- Local research service and Windows launcher.
- RxNorm terminology connector.
- DailyMed v2 SPL connector with XML section parsing.
- openFDA drug-label connector.
- PubMed E-utilities research-lead connector.
- Public URL and HTML section extraction.
- Uploaded PDF, CSV, TSV, HTML, text, and image/chart intake.
- Optional PDF text extraction through `pypdf`.
- Source-response cache with SHA-256, retrieval time, URL, HTTP metadata, and raw file preservation.
- Normalized source model shared by every connector.
- Deterministic label-section to CRD-domain mapping.
- Draft claim and evidence generation with exact source section and locator.
- Duplicate suppression during repository import.
- Medication identity enrichment from RxNorm.
- Source-intake queue population.
- Coverage and unresolved-domain reporting.
- Owner-review requirement retained.
- No automated validation or publication.

## Connector boundaries

- RxNorm supplies terminology and identifiers, not clinical recommendations.
- DailyMed and openFDA draft labeling-derived claims.
- PubMed supplies literature research leads; it does not draft clinical recommendations from abstracts.
- PDF extraction preserves page locators when `pypdf` is installed.
- Image/chart intake is preserved and flagged for manual/OCR review; chart digitization is not falsely claimed.
- Y-site compatibility, stability, CRRT, tube administration, therapeutic substitutions, and formulary alternatives remain separate research domains when authoritative free sources are unavailable.

## Validation performed

- JavaScript syntax passed `node --check`.
- All Python modules passed `py_compile`.
- Four automated research-engine tests passed.
- Tests verify HTML section extraction, CSV table extraction, exact locator creation, and that orchestration outputs remain draft.
- Local HTTP health endpoint tested.

## Environment limitation

This Linux build environment could not resolve external API hosts, so live internet connector calls were not claimed as executed. The connectors use the official HTTPS endpoints and are ready for Windows testing in the next distribution build.
