Two healthcare AI products built on the Signal-Loop foundation.
| Product | What it does | Path |
|---|---|---|
| Lumen | Formal-verification meta-layer for individual clinical recommendations. | lumen/ |
| Vigil | Workspace-scale adverse-event horizon scanner. | vigil/ |
| shared/ | FHIR client, audit chain, ed25519 signing, LLM wrapper, types. | shared/ |
Together: Lumen verifies every prospective clinical recommendation; Vigil detects every retrospective adverse-event pattern. Forward proof + backward surveillance = complete clinical-AI safety stack.
This repo evolved from the Signal-Loop project's two earlier iterations (MedSafe MCP + Concord MCP, both now absorbed into Lumen). See archive/ for the original code and archive/SIGNAL_LOOP_OLD_README.md for the original project README.
