Cross-verified status word 4 bit positions against the FPGA word builder (usb_data_interface.v:376-380, usb_data_interface_ft2232h.v:675-679) and the GUI parser (radar_protocol.py:252-257) — all positions match. No production change needed; the gap was that nothing in the test suite caught a future drift between the two sides. Added test_parse_status_word4_layout_co_spec: a single canonical layout table is the source of truth; for each field the test sets only that field to its max value, builds the status packet via the existing FPGA-builder-mirror _make_status_packet, parses, and asserts the field round-trips exactly AND every other field reads back zero. Catches both LSB drift and width drift on either side of the wire. Pre-checks that widths plus the reserved [9:2] gap sum to 32 and that no two fields overlap. Also fixed test_default_shapes — stale (64,32)/(64,) literals predated the GUI-C1 / Q3 alignment that bumped NUM_RANGE_BINS 64 -> 512. test_v7 was updated at the time, this one was missed. Replaced with references to NUM_RANGE_BINS/NUM_DOPPLER_BINS so any future bin-count change auto-updates the assertion. Suite now 180/180 PASS.
