Strip the host-side parser/dashboard/test references for the FPGA
registers retired in commit 1: host_radar_mode (opcode 0x01),
host_trigger_pulse (opcode 0x02), and host_range_mode (opcode 0x20).
The v7 backend (models.py / software_fpga.py / processing.py) had no
references — only the parser, dashboard, and Tk test file did.
- radar_protocol.py: drop Opcode.RADAR_MODE / TRIGGER_PULSE / RANGE_MODE
enum members; rebuild the doc table around the surviving opcodes; drop
StatusResponse.radar_mode and StatusResponse.range_mode fields; drop
the two parse-status assignments (sr.radar_mode = words[0]>>22 and
sr.range_mode = words[4] & 0x03); update the layout comments on words
0 + 4 to mark the freed bits as reserved-0. Acquisition loop log line
switches from "mode=X stream=Y" to "stream=Y chirps/elev=Z" — radar
mode is no longer a runtime concept.
- v7/dashboard.py: delete the "Radar Mode Off" (0x01) and "Trigger Chirp"
(0x02) QPushButtons from the operations group; remove "Mode:" and
"Range Mode:" fields from _update_status_display.
- test_GUI_V65_Tk.py: drop mode + range_mode kwargs from the
_make_status_packet helper; update the word-4 layout co-spec test
(range_mode entry deleted, reserved span widened from [9:2] to [9:0],
sanity-check sum bumped from used+8 to used+10); delete
test_parse_status_range_mode + test_radar_mode_names; rename
test_agc_and_range_mode_coexist → test_agc_fields_coexist_with_mismatch
with chirps_mismatch replacing range_mode as the coexisting field;
drop 0x01 / 0x02 / 0x20 from test_all_rtl_opcodes_present's expected
set.
GUI tests: 118/0 (test_GUI_V65_Tk) + 152/0 (test_v7). FPGA regression
unchanged at 42/0/0.
