Schema already in 001_init.sql; this is just the Go store layer. IO markers are project-scoped wall-outlet terminators (a cable's "this end plugs into a wall socket outside the diagram" endpoint). Power-by-convention; no schema-level type enforcement. - CreateIOMarker validates frame_id is in the same project (cross-project ref → ErrInvalidInput), defaults label to "IO" when blank. - GetIOMarker is project-scoped — wrong-project read returns ErrNotFound. - UpdateIOMarker uses the FrameRef tri-state for frame_id (same as DeviceUpdate) so callers can clear it explicitly. - DeleteIOMarker is direct delete — ON DELETE SET NULL from the schema drops the io_markers.frame_id ref cleanly when the frame is deleted (verified by TestDeleteFrame_SetsIOMarkerFrameIDToNull). Snapshot now populates IOMarkers from the store; field type tightened from []any to []IOMarker. 7 new table-driven tests, all green with -race.
