Addresses the remaining actionable items from
docs/DEVELOP_AUDIT_2026-04-19.md after commit 3f47d1e.
XDC (dead waivers — F-0.4, F-0.5, F-0.6, F-0.7):
- ft_clkout_IBUF CLOCK_DEDICATED_ROUTE now uses hierarchical filter;
flat net name did not exist post-synth.
- reset_sync_reg[*] false-path rewritten to walk hierarchy and filter
on CLR/PRE pins.
- adc_clk_mmcm.xdc ft601_clk_in references replaced with foreach-loop
over real USB clock names, gated on -quiet existence.
- MMCM LOCKED waiver uses REF_PIN_NAME filter instead of the
previously-missing u_core/ literal path.
CDC (F-1.1, F-1.2, F-1.3):
- Documented the quasi-static-bus stability invariant above the
FT601 cmd_valid toggle block.
- cdc_adc_to_processing gains an `overrun` output; the two CIC->FIR
instances feed a sticky cdc_cic_fir_overrun flag surfaced on
gpio_dig5 so silent sample drops become visible to the MCU.
- Removed the dead mixers_enable synchronizer in ddc_400m.v; the _sync
output was unused and every caller ties the port to 1'b1.
Diagnostics (F-6.4):
- range_bin_decimator watchdog_timeout plumbed through receiver
and top-level, OR'd into gpio_dig5.
ADAR (F-4.7):
- delayUs() replaced with DWT cycle counter; self-initialising
TRCENA/CYCCNTENA, overflow-safe unsigned subtraction.
Regression: tb_cdc_modules.v 57/57 passes under iverilog after
the cdc_modules.v change. Remote Vivado verification in progress.
Addresses findings from docs/DEVELOP_AUDIT_2026-04-19.md:
P0 source-level:
- F-4.3 ADAR1000_Manager::adarSetTxPhase now writes REG_LOAD_WORKING
with LD_WRK_REGS_LDTX_OVERRIDE (0x02) instead of 0x01. Previous value
toggled the LDRX latch on a TX-phase write, so host TX phase updates
never reached the working registers.
- F-6.1 DDC mixer_saturation / filter_overflow / diagnostics were deleted
at the receiver boundary. Now plumbed to new outputs on
radar_receiver_final (ddc_overflow_any, ddc_saturation_count) and
aggregated into gpio_dig5 in radar_system_top. Added mark_debug
attributes for ILA visibility. Test/debug inputs tied low explicitly.
- F-0.8 adc_clk_mmcm.xdc set_clock_uncertainty: removed invalid -add
flag (Vivado silently rejected it, applying zero guardband). Now uses
absolute 0.150 ns which covers 53 ps jitter + ~100 ps PVT margin.
P1:
- F-4.2 adarSetBit / adarResetBit reject broadcast=ON — the RMW sampled
a single device but wrote to all four, clobbering the other three's
state.
- F-4.4 initializeSingleDevice returns false and leaves initialized=false
when scratchpad verification fails; previously marked the device
initialized anyway so downstream PA enable could drive a dead bus.
- F-6.2 FIR I/Q filter_overflow ports, previously unconnected, now OR'd
into the module-level filter_overflow output.
- F-6.3 mti_canceller exposes 8-bit saturation counter. Saturation was
previously invisible and produces spurious Doppler harmonics.
Verification:
- 27/27 iverilog testbenches pass
- 228/228 pytest pass (cross-layer contract + cosim)
- MCU unit tests 51/51 + 24/24 pass
- Remote Vivado 2025.2 build: bitstream writes; 400 MHz mixer pipeline
now shows WNS -0.109 ns which MATCHES the audit's F-0.9 prediction
that the design only closed because F-0.8's guardband was silently
dropped. ft_clkout F-0.9 remains a show-stopper (requires MRCC pin
move), tracked separately.
Not addressed in this PR (larger scope, follow-up tickets):
F-0.4, F-0.5, F-0.6, F-0.7, F-0.9, F-1.1, F-1.2, F-2.2, F-3.2, F-4.1,
F-4.7, F-6.4, F-6.5.
Three conflicts — all resolved in favor of develop, which has a more
refined version of the same work this branch introduced:
- radar_system_top.v: develop's cleaner USB_MODE=1 comment (same value).
- run_regression.sh: develop's ${SYSTEM_RTL[@]} refactor + added
USB_MODE=1 test variants.
- tb/radar_system_tb.v: develop's ifdef USB_MODE_1 to dump the correct
USB instance based on mode.
The 400 MHz reset fan-out fix (nco_400m_enhanced, cic_decimator_4x_enhanced,
ddc_400m) and ADAR1000 channel-indexing fix remain intact on this branch.
Replace direct !reset_n async sense with a registered active-high reset_h
(max_fanout=50) in nco_400m_enhanced, cic_decimator_4x_enhanced, and
ddc_400m. The prior single-LUT1 / 700+ load net was the root cause of
WNS=-0.626 ns in the 400 MHz clock domain on the xc7a50t build. Vivado
replicates the constrained register into ≈14 regional copies, each driving
≤50 loads, closing timing at 2.5 ns.
Change radar_system_top default USB_MODE from 0 (FT601) to 1 (FT2232H).
FT601 remains available for the 200T premium board via explicit parameter
override; the 50T production wrapper already hard-codes USB_MODE=1.
Regression: add usb_data_interface_ft2232h.v to PROD_RTL lint list and
both system-top TB compile commands; fix legacy radar_system_tb hierarchical
probe from gen_ft601.usb_inst to gen_ft2232h.usb_inst.
Golden reference files (rtl_bb_dc.csv, rx_final_doppler_out.csv,
golden_doppler.mem) regenerated to reflect the +1-cycle registered-reset
boundary behaviour; Receiver golden-compare passes 18/18 checks.
All 25 regression tests pass (0 failures, 0 skipped).

The four channel-indexed ADAR1000 setters (adarSetRxPhase, adarSetTxPhase,
adarSetRxVgaGain, adarSetTxVgaGain) computed their register offset as
`(channel & 0x03) * stride`, which silently aliased CH4 (channel=4 ->
mask=0) onto CH1 and shifted CH1..CH3 by one. The API contract (1-based
CH1..CH4) is documented in ADAR1000_AGC.cpp:76 and matches the ADI
datasheet; every existing caller already passes `ch + 1`.
Fix: subtract 1 before masking -- `((channel - 1) & 0x03) * stride` --
and reject `channel < 1 || channel > 4` early with a DIAG message so a
future stale 0-based caller fails loudly instead of writing to CH4.
Adds TestTier1Adar1000ChannelRegisterRoundTrip (9 tests) which closes
the loop independently of the driver:
- parses the ADI register map directly from ADAR1000_Manager.h,
- verifies the datasheet stride invariants (gain=1, phase=2),
- auto-discovers every C++ TU under MCU_LIB_DIR / MCU_CODE_DIR so a
new caller cannot silently escape the round-trip check,
- asserts every caller's channel argument evaluates to {1,2,3,4} for
ch in {0,1,2,3} (catches bare 0-based or literal-0 callers at CI
time before the runtime bounds-check would silently drop them),
- round-trips each (caller, ch) through the helper arithmetic and
checks the final address equals REG_CH{ch+1}_*.
Adversarially validated: reverting any one helper, all four helpers,
corrupting the parsed register map, injecting a bare-ch caller, and
auto-discovering a literal-0 caller in a fresh TU each cause the
expected (and only the expected) test to fail.
Stacked on fix/adar1000-vm-tables (PR #107).
The ADAR1000 vector-modulator I/Q lookup tables VM_I[128] and VM_Q[128]
were declared but defined as empty initialiser lists since the first
commit (5fbe97f). Every call to adarSetRxPhase / adarSetTxPhase therefore
wrote (I=0x00, Q=0x00) to registers 0x21/0x23 (Rx) and 0x32/0x34 (Tx)
regardless of the requested phase state, leaving beam steering completely
non-functional in firmware.
This commit:
* Populates VM_I[128] and VM_Q[128] from ADAR1000 datasheet Rev. B
Tables 13-16 (p.34) on a uniform 2.8125 deg grid (360 / 128 states).
Byte format: bits[7:6] reserved 0, bit[5] polarity (1 = positive
lobe), bits[4:0] 5-bit unsigned magnitude - exactly as specified.
* Removes VM_GAIN[128] declaration and (empty) definition. The
ADAR1000 has no separate VM gain register; per-channel VGA gain is
set via CHx_RX_GAIN (0x10-0x13) / CHx_TX_GAIN (0x1C-0x1F) by
adarSetRxVgaGain / adarSetTxVgaGain. VM_GAIN was never populated,
never read anywhere in the firmware, and its presence falsely
suggested a missing scaling step in the signal path.
* Adds 9_Firmware/tests/cross_layer/adar1000_vm_reference.py: an
independently-derived ground-truth module containing the full
datasheet table plus byte-format / uniform-grid / quadrant-symmetry
/ cardinal-point invariant checkers and a tolerant C array parser.
* Adds TestTier2Adar1000VmTableGroundTruth (9 tests) to
test_cross_layer_contract.py, including a tokenising C/C++
comment+string stripper used by the VM_GAIN reintroduction guard,
and an adversarial self-test that corrupts one byte and asserts
the comparison detects it (defends against silent bypass via
future fixture/parser refactors).
Adversarially validated: removing the firmware definitions, flipping
a single byte, or reintroducing VM_GAIN as code each cause the suite
to fail; restoring causes it to pass. VM_GAIN appearing inside string
literals or comments correctly does NOT trip the guard.
Closes the empty-table half of the ADAR1000 phase-control bug class.
The separate channel-rotation issue (#90) will be addressed in a
follow-up PR.
Refs: 7_Components Datasheets and Application notes/ADAR1000.pdf
Rev. B Tables 13-16 p.34
The firmware uses the C++ ADAR1000_Manager class exclusively. The C-style
driver pair (adar1000.c, 693 LoC; adar1000.h, 294 LoC) has no external
call sites:
grep -rn "Adar_Set|Adar_Read|Adar_Write|Adar_Soft" 9_Firmware
grep -rn "AdarDevice|AdarBiasCurrents|AdarDeviceInfo" 9_Firmware
Both return hits only inside adar1000.c/h themselves. ADAR1000_Manager.h
has its own copies of REG_CH1_*, REG_INTERFACE_CONFIG_A, etc. and does
not include adar1000.h. main.cpp had a lone #include "adar1000.h" but
referenced no symbols from it; the REG_* macros it uses resolve through
ADAR1000_Manager.h on the next line.
No behaviour change: the deleted code was unreachable.
Side note on #90: adar1000.c contained a second copy of the
REG_CH1_* + (channel & 0x03) channel-rotation pattern tracked in #90
(lines 349, 397-398, 472, 520-521). This commit does not fix#90 --
the live path in ADAR1000_Manager.cpp still needs the channel-index
fix -- but it removes the dormant copy so the bug has one less place
to hide.

PR #93 added a 2-frame confirmation debounce so a single-sample GPIO
glitch cannot flip MCU outer-loop AGC state. The debounce is load-bearing
for the "prevents a single-sample glitch" guarantee in the PR body, but
no existing test enforces its structure — test_mcu_reads_dig6_before_agc_gate
only checks that HAL_GPIO_ReadPin(FPGA_DIG6, ...) and `outerAgc.enabled =`
appear somewhere in main.cpp, which a naive direct assignment would still
pass.
Add test_mcu_dig6_debounce_guards_enable_assignment to
TestTier1AgcCrossLayerInvariant, verifying four structural invariants of
the debounce:
1. Current DIG_6 sample captured in a local variable
2. Static previous-frame variable defaulting to false (matches FPGA
boot: host_agc_enable resets 0)
3. outerAgc.enabled assignment gated by `now == prev`
4. Previous-frame variable advanced each frame
Verified test fails on a naive patch that removes the guard and passes
on the current PR #93 implementation. Full cross-layer suite stays at
0 failures (36/36 pass locally).
Resolve cross-layer AGC control mismatch where opcode 0x28 only
controlled the FPGA inner-loop AGC but the STM32 outer-loop AGC
(ADAR1000_AGC) ran independently with its own enable state.
FPGA: Drive gpio_dig6 from host_agc_enable instead of tied low,
making the FPGA register the single source of truth for AGC state.
MCU: Change ADAR1000_AGC constructor default from enabled(true) to
enabled(false) so boot state matches FPGA reset default (AGC off).
Read DIG_6 GPIO every frame with 2-frame confirmation debounce to
sync outerAgc.enabled — prevents single-sample glitch from causing
spurious AGC state transitions.
Tests: Update MCU unit tests for new default, add 6 cross-layer
contract tests verifying the FPGA-MCU-GUI AGC invariant chain.

golden_reference.py: update comment from 'Simplified' to 'Exact' to
match shaun0927's corrected formula.
fpga_model.py: fix adc_to_signed docstring that incorrectly derived
0x7F80 instead of 0xFF00. Verilog '/' binds tighter than '-', so
{1'b0,8'hFF,9'b0}/2 = 0x1FE00/2 = 0xFF00, not 0xFF<<8 = 0x7F80.
Silently skipping Tier 2/3 tests in CI defeats the purpose of running
them. Add a GITHUB_ACTIONS guard that raises RuntimeError at module
load if iverilog or C++ compiler is not found, preventing false-green
CI results from skipped tests.
When an unknown signal is encountered, total is set to -1 but the
loop continues. Subsequent known signals add their widths to -1,
producing incorrect totals (e.g. -1 + 16 = 15 instead of -1).
This can mask genuine truncation bugs in status word packing.
The golden reference used (adc_val - 128) << 9 which subtracts 65536,
but the Verilog RTL computes {1'b0,adc,9'b0} - {1'b0,8'hFF,9'b0}/2
which subtracts 0xFF00 = 65280. This creates a constant 256-LSB DC
offset between the golden reference and RTL for all 256 ADC values.
The bit-accurate model in fpga_model.py already uses the correct RTL
formula. This aligns golden_reference.py to match.
Verified: all 256 ADC input values now produce zero offset against
fpga_model.py.
The default IVERILOG and VVP paths were hardcoded to macOS Homebrew
locations (/opt/homebrew/bin/iverilog). On Ubuntu CI runners, apt
installs iverilog to /usr/bin/, so the Path.exists() check returns
False and all Tier 2 Verilog cosim tests are silently skipped.
Change defaults to bare command names so the existing which-based
fallback at line 57-58 discovers the binary via PATH on any platform.
- Add ERROR_COUNT sentinel to SystemError_t enum
- Change error_strings[] to static const char* const
- Add static_assert to enforce enum/array sync at compile time
- Add runtime bounds check with fallback for invalid error codes
- Add all missing test binary names to .gitignore
The gap3, agc, and gps test binaries (Mach-O executables compiled on macOS)
were accidentally tracked. CI runs on Linux and fails with 'Exec format error'.
Removed from index and added to .gitignore.
FPGA-001: The previous fix derived frame boundaries from chirp_counter==0,
but that counter comes from plfm_chirp_controller_enhanced which overflows
to N (not wrapping at chirps_per_elev). This caused frame pulses only on
6-bit rollover (every 64 chirps) instead of every N chirps. Now wires the
CDC-synchronized tx_new_chirp_frame_sync signal from the transmitter into
radar_receiver_final, giving correct per-frame timing for any N.
STM32-004: Changed ad9523_init() failure path from Error_Handler() to
return -1, matching the pattern used by ad9523_setup() and ad9523_status()
in the same function. Both halt the system, but return -1 keeps IRQs
enabled for diagnostic output.
checkSystemHealth()'s internal watchdog (pre-fix step 9) had two linked
defects that, combined with the previous commit's escalation of
ERROR_WATCHDOG_TIMEOUT to Emergency_Stop(), would false-latch AERIS-10:
1. Cold-start false trip:
static uint32_t last_health_check = 0;
if (HAL_GetTick() - last_health_check > 60000) { trip; }
On the first call, last_health_check == 0, so the subtraction
against a seeded-zero sentinel exceeds 60 000 ms as soon as the MCU
has been up >60 s -- normal after the ADAR1000 / AD9523 / ADF4382
init sequence -- and the watchdog trips spuriously.
2. Stale timestamp after early returns:
last_health_check = HAL_GetTick(); // at END of function
Every earlier sub-check (IMU, BMP180, GPS, PA Idq, temperature) has
an `if (fault) return current_error;` path that skips the update.
After ~60 s of transient faults, the next clean call compares
against a long-stale last_health_check and trips.
With ERROR_WATCHDOG_TIMEOUT now escalating to Emergency_Stop(), either
failure mode would cut the RF rails on a perfectly healthy system.
Fix: move the watchdog check to function ENTRY. A dedicated cold-start
branch seeds the timestamp on the first call without checking. On every
subsequent call, the elapsed delta is captured first and
last_health_check is updated BEFORE any sub-check runs, so early returns
no longer leave a stale value. 32-bit tick-wrap semantics are preserved
because the subtraction remains on uint32_t.
Add test_gap3_health_watchdog_cold_start.c covering cold-start, paced
main-loop, stall detection, boundary (exactly 60 000 ms), recovery
after trip, and 32-bit HAL_GetTick() wrap -- wired into tests/Makefile
alongside the existing gap-3 safety tests.
STM32-006: Remove blocking do-while loop that waited for legacy GUI start
flag — production V7 PyQt GUI never sends it, hanging the MCU at boot.
STM32-004: Check ad9523_init() return code and call Error_Handler() on
failure, matching the pattern used by all other hardware init calls.
FPGA-001: Simplify frame boundary detection to only trigger on
chirp_counter wrap-to-zero. Previous conditions checking == N and == 2N
were unreachable dead code (counter wraps at N-1). Now correct for any
chirps_per_elev value.
- Rename ERROR_STEPPER_FAULT → ERROR_STEPPER_MOTOR to match main.cpp enum
- Update critical-error predicate to include ERROR_TEMPERATURE_HIGH and
ERROR_WATCHDOG_TIMEOUT (was testing stale pre-fix logic)
- Test 4 now asserts overtemp DOES trigger e-stop (previously asserted opposite)
- Add Test 5 (watchdog triggers e-stop) and Test 6 (memory alloc does not)
- Add ERROR_MEMORY_ALLOC and ERROR_WATCHDOG_TIMEOUT to local enum
- 7 tests, all pass
The previous commit accidentally introduced the literal 2-byte sequence
'\r' at the end of two backslash-continuation lines (TESTS_STANDALONE
and the .PHONY list). GNU make on Linux treats that as text rather than
a line continuation, which orphans the following line with leading
spaces and aborts CI with:
Makefile:68: *** missing separator (did you mean TAB instead of 8 spaces?)
Strip the extraneous 'r' so each continuation ends with a real backslash
+ LF.
handleSystemError() only called Emergency_Stop() for error codes in
[ERROR_RF_PA_OVERCURRENT .. ERROR_POWER_SUPPLY] (9..13). Two critical
faults were left out of the gate and fell through to attemptErrorRecovery()'s
default log-and-continue branch:
- ERROR_TEMPERATURE_HIGH (14): raised by checkSystemHealth() when the
hottest of 8 PA thermal sensors exceeds 75 C. Without cutting bias
(DAC CLR) and the PA 5V0/5V5/RFPA_VDD rails, the 10 W GaN QPA2962
stages remain biased in an overtemperature state -- a thermal-runaway
path in AERIS-10E.
- ERROR_WATCHDOG_TIMEOUT (16): indicates the health-check loop has
stalled (>60 s since last pass). Transmitter state is unknown;
relying on IWDG to reset the MCU re-runs startup and re-energises
the PA rails rather than latching the safe state.
Fix: extend the critical-error predicate so these two codes also trigger
Emergency_Stop(). Add test_gap3_overtemp_emergency_stop.c covering all
17 SystemError_t values (must-trigger and must-not-trigger), wired into
tests/Makefile alongside the existing gap-3 safety tests.
Rename radar_dashboard.py -> GUI_V65_Tk.py and add core feature parity
with the v7 PyQt dashboard while keeping Tkinter as the framework:
Replay mode:
- _ReplayController with threading.Event-based play/pause/stop
- Reuses v7.ReplayEngine and v7.SoftwareFPGA for all 3 input formats
- Dual dispatch routes FPGA control opcodes to SoftwareFPGA during
raw IQ replay; non-routable opcodes show user-visible status message
- Seek slider with re-emit guard, speed combo, loop checkbox
- close() properly releases engine file handles on stop/reload
Demo mode:
- DemoTarget kinematics scaled to physical range grid (~307m max)
- DemoSimulator generates synthetic RadarFrames with Gaussian blobs
- Targets table (ttk.Treeview) updates from demo target list
Mode exclusion (bidirectional):
- Connect stops active demo/replay before starting acquisition
- Replay load stops previous controller and demo before loading
- Demo start stops active replay; refuses if live-connected
- --live/--replay/--demo in mutually exclusive CLI arg group
Bug fixes:
- seek() now increments past emitted frame to prevent re-emit on resume
- Failed replay load nulls controller ref to prevent dangling state
Tests: 17 new tests for DemoTarget, DemoSimulator, _ReplayController
CI: all 4 jobs pass (167+21+25+29 = 242 tests)
Add SoftwareFPGA class that imports golden_reference functions to
replicate the FPGA pipeline in software, enabling bit-accurate replay
of raw IQ, FPGA co-sim, and HDF5 recordings through the same
dashboard path as live data.
New modules: software_fpga.py, replay.py (ReplayEngine + 3 loaders)
Enhanced: WaveformConfig model, extract_targets_from_frame() in
processing, ReplayWorker with thread-safe playback controls,
dashboard replay UI with transport controls and dual-dispatch
FPGA parameter routing.
Removed: ReplayConnection (from radar_protocol, hardware, dashboard,
tests) — replaced by the unified replay architecture.
150/150 tests pass, ruff clean.
Bug #1 — Range calibration for Raw IQ Replay:
- Add WaveformConfig dataclass (models.py) with FMCW waveform params
(fs, BW, T_chirp, fc) and methods to compute range/velocity resolution
- Add waveform parameter spinboxes to playback controls (dashboard.py)
- Auto-parse waveform params from ADI phaser filename convention
- Create replay-specific RadarSettings with correct calibration instead
of using FPGA defaults (781.25 m/bin → 0.334 m/bin for ADI phaser)
- Add 4 unit tests validating WaveformConfig math
Bug #2 — Demo + radar mutual exclusion:
- _start_demo() now refuses if radar is running (_running=True)
- _start_radar() stops demo first if _demo_mode is active
- Demo buttons disabled while radar/replay is running, re-enabled on stop
Bug #3 — Refactor adi_agc_analysis.py:
- Remove 60+ lines of duplicated AGC functions (signed_to_encoding,
encoding_to_signed, clamp_gain, apply_gain_shift)
- Import from v7.agc_sim canonical implementation
- Rewrite simulate_agc() to use process_agc_frame() in a loop
- Rewrite process_frame_rd() to use quantize_iq() from agc_sim
- workers.py: Only emit playbackStateChanged on state transitions to
prevent stale 'playing' signal from overwriting pause button text
- dashboard.py: Force C locale on all QDoubleSpinBox instances so
comma-decimal locales don't break numeric input; add missing
'Saturation' legend label to AGC chart
- map_widget.py: Enable LocalContentCanAccessRemoteUrls and set HTTP
base URL so Leaflet CDN tiles/scripts load correctly in QtWebEngine
State machine fixes:
1. Raw IQ replay EOF now calls _stop_radar() to fully restore UI
2. Worker thread finished signal triggers UI recovery on crash/exit
3. _stop_radar() stops demo simulator to prevent cross-mode interference
4. _stop_demo() correctly identifies Mock mode via combo text
5. Demo start no longer clobbers status bar when acquisition is running
6. _stop_radar() resets playback button text, frame counter, file label
7. _start_raw_iq_replay() error path cleans up stale controller/worker
8. _refresh_gui() preserves Raw IQ paused status instead of overwriting
Map/location:
- RawIQReplayWorker now receives _radar_position (GPSData ref) so
targets get real lat/lon projected from the virtual radar position
- Added heading control to Map tab sidebar (0-360 deg, wrapping)
- Manual lat/lon/heading changes in Map tab apply to replay targets
Ruff clean, 120/120 tests pass.
Add a 4th connection mode to the V7 dashboard that loads raw complex IQ
captures (.npy) and runs the full FPGA signal processing chain in software:
quantize → AGC → Range FFT → Doppler FFT → MTI → DC notch → CFAR.
Implementation (7 steps):
- v7/agc_sim.py: bit-accurate AGC runtime extracted from adi_agc_analysis.py
- v7/processing.py: RawIQFrameProcessor (full signal chain) + shared
extract_targets_from_frame() for bin-to-physical conversion
- v7/raw_iq_replay.py: RawIQReplayController with thread-safe playback
state machine (play/pause/stop/step/seek/loop/FPS)
- v7/workers.py: RawIQReplayWorker (QThread) emitting same signals as
RadarDataWorker + playback state/index signals
- v7/dashboard.py: mode combo entry, playback controls UI, dynamic
RangeDopplerCanvas that adapts to any frame size
Bug fixes included:
- RangeDopplerCanvas no longer hardcodes 64x32; resizes dynamically
- Doppler centre bin uses n_doppler//2 instead of hardcoded 16
- Shared target extraction eliminates duplicate code between workers
Ruff clean, 120/120 tests pass.
v7/__init__.py: wrap workers/map_widget/dashboard imports in try/except
so CI runners without PyQt6 can still test models, processing, hardware.
test_v7.py: skip TestPolarToGeographic when PyQt6 unavailable, split
TestV7Init.test_key_exports into core vs PyQt6-dependent assertions.
