Use embedded .gdb_index and .debug_names to select compilation units for lazy fast-parser materialization instead of scanning every unit's debug info at startup. Validate native indexes before selection and fall back to a full DWARF scan when no usable index is available. Report index selection in CLI and TUI loading flows.
