MM b/19 --- Paper b19: SGIR Basic Gap-of-Germs Epidemiology
***********************************************************************

**Matheo-b19** presents the SGIR (Susceptible-Gap-Infected-Removed) pandemic modeling framework, extending the classic SIR model by tracking the Gap between Susceptible and Infected populations. This gap governs pandemic dynamics: increasing the "Gap of Germs" through coordinated non-pharmaceutical interventions can reduce pandemic infections by orders of magnitude.

The model demonstrates that simple coordinated changes in viral Shed, Decay, and Catch rates can stop a 289+ million pandemic at 1.5 million infections. Using Evolvix simulations and 2020 epidemiological data, the paper shows that the biological knowledge for pandemic control existed early in COVID-19, but coordination mechanisms for implementing that knowledge did not.

Development trail
===================

- **Original location:** The SGIR papers originated in the STa2-WWV (World War V on Virulence) stadium as part of pandemic preparedness analysis
- **Migration rationale:** Moved to HEAVEN series for navigation accessibility (4-level navbar limitation) while maintaining thematic connections
- **Session logs:** Development history preserved in original STa2-WWV documentation and HEAVEN series development logs
