Flatten chirp_scheduler.v to single-FSM auto-scan. Mode 00 (STM32 pass-through), mode 10 (single-chirp debug) and mode 11 (track dwell) FSM branches were all half-implemented and unreachable in production: MCU dispatcher was deleted in F-2.1; mode 11 inputs were tied to constants in radar_receiver_final; mode 10 debug_wave_sel was hardcoded to SHORT. The case-switch wrapper, watchdog, effective_mode mux, and all host_track_* / host_debug_wave_sel / host_trigger plumbing are removed. Strip host_radar_mode (opcode 0x01), host_trigger_pulse (opcode 0x02), and host_range_mode (opcode 0x20). The mode register had no consumer after the single-mode flatten; the range_mode register was already write-only telemetry (declared as input in radar_receiver_final but never read). The runtime 3km vs 20km presentation on a 200T build is driven by host_subframe_enable (0x19) + per-waveform chirp/listen cycles (0x10-0x18) — no separate mode field needed. Strip stm32_new_elevation / stm32_new_azimuth GPIOs and the elevation_counter / azimuth_counter regs in plfm_chirp_controller_v2. The FPGA-side counters had no consumer (status pack never carried them; on 50T they went to _nc; on 200T to unconstrained outputs). MCU software counters n/y reach the GUI via USB-CDC on a separate channel. USB status word 0 bits [23:22] (was radar_mode) and word 4 bits [1:0] (was range_mode) are now reserved zeros — host parser keeps the same byte offsets. Files modified: chirp_scheduler.v - flatten to single FSM (~155 LOC delta) plfm_chirp_controller_v2.v - strip counter blocks + ports radar_transmitter.v - strip elev/azim CDC + edge detectors + ports radar_receiver_final.v - strip host_mode/range_mode/trigger + STM32 toggle ports radar_system_top.v - strip regs, opcodes 0x01/0x02/0x20, status_*_mode wiring, top-level ports radar_system_top_50t.v - strip _nc wires + stm32_new_elev/azim + tie-offs radar_system_top_te0713_umft601x_dev.v - strip status_radar_mode/range_mode ties usb_data_interface.v - drop status_*_mode ports, reserve word 0 [23:22] + word 4 [1:0] usb_data_interface_ft2232h.v - same as above radar_params.vh - strip RP_MODE_* / RP_RANGE_MODE_* / RP_OP_RADAR_MODE / RP_OP_TRIGGER_PULSE / RP_OP_RANGE_MODE / RP_DEF_TRACK_* Regression will fail at this commit due to TB references to deleted signals (host_radar_mode, status_range_mode, etc.) — TB cleanup follows in commit 2.
