Simulated hospital node agent

The agent validates local tables and exports only allowed metrics. Raw rows remain inside the node.

Node status

The coordinator sees status and aggregates; it does not receive patients, specimens, isolates, or row-level AST results.

Node Agent API (FastAPI microservice)

Each node exposes a local REST API. The webapp tries to connect in real time; if the microservice is not running, it falls back to static aggregates.

Node agent microservice not detected. Showing static data. Start with: python -m node_agent (from 09_node_agent_simulado/).

Module README

09 Simulated Hospital Node Agent

This module simulates a local hospital node agent. The agent reads the relational AMR model from module 08, validates minimum quality, and exports only permitted artifacts.

Core idea

In PROTEONEXT, sensitive data should not move to a central repository. The correct pattern is:

Local node data
        |
        v
Node agent
        - validates schema
        - computes quality
        - executes aggregated query
        - prepares permitted export
        |
        v
Only metrics, aggregates, and non-identifiable evidence leave

Outputs

The script generates:

  • salida/node_exports/<node_id>_export.json
  • salida/coordinator_summary.json

Each export includes:

  • Row count per table.
  • Minimum quality.
  • Count by pathogen.
  • Resistance by antibiotic.
  • Genomics availability.
  • Simulated job hash.
  • raw_rows_exported: 0

Run

From Desarrollo:

& 'C:\ProgramData\miniconda3\python.exe' .\09_node_agent_simulado\node_agent.py
