…nt row loss Scalar (sorted/bitmap) global-index queries used the vector/full-text `global-index.search-mode` = fast, which returns no unindexed ranges, so rows committed but not yet covered by the index were pruned before being read and `WHERE <indexed_col> = X` silently returned incomplete results. - Add `scalar-index.search-mode` (default `full`). Resolution priority: explicit `scalar-index.search-mode` -> an explicit `global-index.search-mode` (inherited) -> default `full`. - Thread an optional `search_mode` through DataEvolutionGlobalIndexCoverage and DataEvolutionGlobalIndexScanner.unindexed_rows. - Only the pure scalar scan (file_scanner) passes the scalar mode. Vector / full-text callers leave it unset and keep the fast default, so a vector scan with a scalar filter is not widened into a full-table brute-force scan.
