How is ExposureConfiguration set in ProteGoSafe ?

[pdehaye]

The CoronaRiskScoring project is trying to assess how different contact tracing apps are being parametrized. We are first focusing on apps using the Apple API as it will enable quickest comparison.

Project considered
We are looking at ProteGoSafe.

What we need
We need pointers to the places in the code where the following parameters are set:

• ENExposureConfiguration.attenuationLevelValues,
• ENExposureConfiguration.daysSinceLastExposureLevelValues,
• ENExposureConfiguration.durationLevelValues,
• ENExposureConfiguration.transmissionRiskLevelValues and
• ENExposureConfiguration.metadata.attenuationDurationThresholds

Nice to have
We would also like to understand what is done with ENExposureDetectionSummary and ENExposureInfo, after the risks are calculated.

Excellent to have
This is only the beginning for us. We want the above so we can track how the parameters are being changed. It is likely actually that this is passed dynamically to the apps. If so, we need to know the process behind these changes, so we can ask the right people for this information.

If you have pointers in the right direction, they would be greatly appreciated.
