+-- 003_collections_propertyvalues_case.sql — repair a quoting mistake in 002.
+-- 002 created CollectionItem.propertyValues unquoted, so PostgreSQL folded it
+-- to lowercase "propertyvalues" on databases where the migration's own DDL
+-- materialized the table (existing installs upgraded through the ledger).
+-- schema.sql and the API contract use the quoted camelCase name. 002 is
+-- recorded and immutable, so the repair ships as this guarded rename; on
+-- databases built from the corrected schema.sql the column already has the
+-- right name and this is a no-op.
