# Deferred and roadmap context

This file is background only. Do not implement these items merely because they are mentioned here.

## Propagation model

After the manual audit, Marc intends to revisit and improve KST4Contest propagation modelling.

Exploration areas include:

- higher-density Copernicus GLO-30 terrain sampling;
- Fresnel-zone analysis;
- diffraction modelling;
- simplified ray tracing / multi-segment paths;
- VHF/UHF/microwave contest applicability, including around 1296 MHz and above;
- practical contest-oriented prediction rather than academic complexity for its own sake.

This requires a fresh concept before implementation.

## Rule

Roadmap context must never silently enlarge the scope of a current task.
