Overview

Walks a sharded downloads directory and collects every IRDI referenced by a class .xls that points to a non-class entity (property, unit, value-list, value-term). The output manifest drives the per-entity scraper Pass 2 — see TODO.cdd-editor/43-scraper-pass-2-per-entity.md.

Source columns on the CLASS .xls (parsed by Opencdd::Klass):

applicable_property_irdis   (MDC_P014) → property
imported_property_irdis     (MDC_P090) → property (cross-dict)
is_case_of_irdis            (MDC_P013) → class (cross-dict)
sub_class_selection_irdis   (MDC_P016) → class

Cross-dictionary IRDIs are partitioned by their source scheme so the scraper can pick the right Dictionary config. Properties referenced in applicable_property_irdis of a class in dict A that point at dict B's IRDI space are emitted with source_scheme: B.
