research: Wikibase/Wikidata deep dive (entity-statement graph, SPARQL); UC-73-75

SHARD-WP-0003 T2. Structure & native-query far-end: typed knowledge graph
(items/properties, statements = claim+qualifiers+references+rank), RDF
projection + SPARQL (WDQS/Blazegraph) incl. federated SERVICE, opaque stable
Q/P identity (labels-as-annotation), statement-level provenance. UC-73
(typed-graph shard, lossy render), UC-74 (SPARQL + federated query), UC-75
(per-assertion provenance). Enriched UC-34/58/52/24. Marks T2 done.
Feeds SHARD-WP-0002 T12/T16.
