Ragnor Comerford 505303f93e test(engine): pin Lance scalar-index coverage + system-column/deletion-metadata surface ... Add three Lance surface guards de-risking a future persisted-adjacency cache: - a compile-only guard pinning the fragment physical_rows + index-detail surface that key_column_index_coverage mirrors (the C6 fallback); - a runtime probe confirming a scalar BTREE on the system column _row_last_updated_at_version is not buildable via the normal create-index path (the column is not in the user schema), so a version-column range delta is not viable as drafted; - a runtime probe confirming per-fragment deletion metadata (deletion_file.num_deleted_rows) is available as cheap O(fragments) metadata, the primitive a fragment-coverage delete model would rely on. The probes turn the two largest substrate assumptions into green/red CI facts before any cache work begins.		2026-06-09 09:34:03 +02:00
