schema

The model of what is in the database: which paths exist, how often, with what types.

Folded fresh on every call rather than served from the cache behind query. The cache exists to keep planning cheap; a caller asking for the model is asking a question about the data now, and answering it from a fold taken at some earlier flush would be a different answer wearing the same name. InferredSchema.coverage reports how much of the store it speaks for.
