- Extract shared helpers to database/queries/common.py: - MAX_BIND_PARAMS, calculate_rows_per_statement, iter_chunks, iter_row_chunks - build_visible_owner_clause - Remove duplicate _compute_filename_for_asset, consolidate in path_utils.py - Remove unused get_asset_info_with_tags (duplicated get_asset_detail) - Remove redundant __all__ from cache_state.py - Make internal helpers private (_check_is_scalar) Amp-Thread-ID: https://ampcode.com/threads/T-019c2ad9-9432-7451-94a8-79287dbbb19e Co-authored-by: Amp <amp@ampcode.com>
