What

ObjectStorageSchema now generates three more indexes. Each is appended to its table's list, so the existing ix_<table>_<n> names do not change:

ix_object_storage_object_7 on object_storage_object (folder_id), for the Folder -> Objects child list
ix_object_storage_object_version_2 on object_storage_object_version (object_id), for Object -> Versions
ix_object_storage_object_reference_3 on object_storage_object_reference (object_id), for Object -> Referenced by and the object lookups in ActionSupport

Why

These relations (ObjectStorageTables.RELATIONS) filter on the parent id alone. Every existing index on these tables leads with bucket_id, so the child lists scan the table.

This came out of an index audit of the qbits installed on kof22.

Tests

New TablesAndConfigTest.testChildListColumnsAreIndexed pins the three generated statements and checks that an existing name keeps its number.
./mvnw verify is green locally.

Hosts that copied the generated SQL need a changeset with the same statements. kof22's is in its features/2026-10-14-qbit-indexes.sql, using these same index names.
