Description: Implements deterministic classification keys for the World
    Reference Base for Soil Resources 2022 (4th edition) and the Brazilian
    System of Soil Classification ('SiBCS', 5th edition). Provides a unified
    profile representation with explicit per-attribute provenance, multimodal
    extraction from field reports and photos via vision-language models,
    spatial priors from 'SoilGrids' and national soil maps, and gap-filling of
    soil attributes from Vis-NIR or MIR spectra via the Open Soil Spectral
    Library ('OSSL'). The taxonomic key itself is never delegated to a language
    model; LLMs are restricted to schema-validated extraction. Each
    classification result reports a key trace, a provenance-aware evidence
    grade, and ambiguities that further measurement would resolve.
