Slot: Variable-Specific Extensions (variable_specific_extensions)
Methodology blocks that only apply to particular variable families — present when the variable calls for them, omitted otherwise. Today that is derived heat metrics; future families (air quality, pollen, …) plug in here the same way.
Why this slot matters
Separates methodology blocks that only exist for certain variable families from the universal anatomy, so a reader knows their absence is normal for other variables rather than a completeness failure — and future families gain an obvious plug-in point.
In plain terms
Some variables need extra paperwork. A heat index, for example, is computed from temperature and humidity with a particular formula, so it carries an extra methodology block; a plain temperature record does not. This section is where those variable-specific extras live.
