# RC4 — Active Populated Knowledge

## Implemented
- Added active Clinical Reasoning Database starter library.
- Populated 51 medication records.
- Added active AHK runtime lookup.
- Patient analysis now matches captured medication orders against the active CRD.
- Clinical Review output now includes:
  - matched medication concepts
  - therapeutic class
  - pharmacologic class
  - active review domains
  - generated review cues
  - therapeutic substitution candidates
  - unmatched captured orders

## Purpose
Make the knowledge visibly active during real-world testing instead of sitting passively in JSON/workbench storage.

## Still required before clinical publication
- Field-by-field claim extraction
- Exact source section/locator evidence
- Owner review
- Conflict resolution
- Approved release generation
