On Cocoa the full-bitmap alpha-restore pass is unnecessary: Canvas
operations keep alpha at $FF and the cached grid background is opaque,
so removing it cuts a full-frame O(W*H) pass per spectrum frame with no
visual change (verified on macOS).
Kept under {$IFNDEF DARWIN} for Qt6/win32 (different drawing backends
may zero alpha on antialiased edges) until visually verified there.

WaterfallView: drop per-frame TLazIntfImage + LoadFromIntfImage (device
bitmap recreation + full pixel-format conversion every frame). Write
pixels directly into the bitmap via BeginUpdate/ScanLine like
SpectrumView already does, with platform-native byte order (ARGB on
Cocoa, BGRA elsewhere).
Replace per-pixel float colorization with a 512-entry dB->color LUT
rebuilt only when WfLow/WfHigh/theme change beyond a small threshold.
Turn the bitmap itself into a ring buffer: each frame builds a single
new row and writes one ScanLine; scrolling is done at paint time via two
CopyRect calls. Removes both full-frame passes per frame (image memmove
+ buffer->bitmap copy), cutting per-frame cost from O(W*H) to O(W). TX
mode preserved by leaving out-of-span columns untouched in the row buf.
SpectrumView: rewrite the per-frame alpha-restore pass from a strided
per-byte loop to a sequential per-dword OR with the alpha mask
(bit-identical output, sequential memory access).

On macOS Cocoa, TBitmap.pf32bit stores pixels in ARGB order
(byte0=A, byte1=R, byte2=G, byte3=B) rather than BGRA used on
Linux/Windows. All raw ScanLine pixel blending and channel mapping
is now guarded with { DARWIN} to use the correct offsets.
Also fix PortAudio library discovery on macOS: probe .dylib names
(including Homebrew paths) before falling through to .so/.dll.
- ApplyChannel now sets TrkDrive from Ch.Power; saves pre-channel level in
FPreChannelPower (works around TrkDriveChange clearing the field on assignment)
- Power is restored when tuning away from channel (CheckChannelActive) or on
first VFO movement after returning to band with no active channel (ApplyVfoA)
- Manual drive slider move clears FPreChannelPower so restore is skipped

- New ChannelStore.pas: TChannel record + JSON persistence (channels.json)
- New ChannelsForm.pas: full channel editor (list + fields, pre-fills from current radio state)
- CH button in RX block: left-click opens dropdown, right-click opens editor
- Active channel: button highlights with channel name, deactivates on VFO move
- ApplyChannel: auto-switches XVTR/HF band based on channel frequency; saves old
band state before switching to prevent cache corruption
- SaveCurrentBand: skip save when VFO > 61 MHz (prevents HF cache corruption
from VHF channel application without XVTR)
- DeactivateXvtr: save full XVTR state (was only saving LastFreq)
- CTCSS/RPT from channel marked as auto: cleared automatically when tuning away
from channel frequency; survives band switches via FXvtrSettings auto-flags
- TXvtrEntry: add LastCTCSSAutoActive, LastFMRptAutoActive fields

- Add PanelRXBlock between TX and Band with CTUN, VOL, NR/NB/SNB/ANF/MUTE
- Move AGC panel to sit directly below RX block for logical RX grouping
- Move DUP button into TX panel below MOX/TUN
- Rename PanelRX → PanelAGC to match its content
- Standardize block label top (2px) and first-control top (16px) across all
panels: AGC, SQL, CTCSS, STEP were inconsistent
- Fix left panel width restore after hide: save actual DPI-scaled width before
zeroing instead of hardcoding 232, preventing panel truncation on Win32 with
display scaling enabled

(ClickFreq div StepHz)*StepHz always snapped downward; replaced with
((ClickFreq + StepHz/2) div StepHz)*StepHz so clicks above the midpoint
between two steps correctly snap to the higher one.

RefreshAudioDevices was firing OnRXDevChange/OnTXDevChange when restoring
the combo selection, which called ApplyAudioDevice(-1,'') and wiped
FAudioOutDevName/FAudioInDevName before LoadValues could use them.

Extract helpers out of MainForm into structured modules:
- BoardUtils: BoardTypeName, FreqToBandIdx (removes duplication with DeviceForm)
- WisdomBuilder: TWisdomBuildThread + TWisdomProgressDialog
- UISync: TDeviceFoundSync/TStatusUISync/TDDCSeqSync via callbacks
- PlatformUtils: HasOpenGLSpectrumSwitch, CurrentScreenDPI
Minor cleanup: unused local constants, stale comments in AudioOutput.
Replaces TProgressBar in TWisdomProgressDialog with TFlatProgressBar,
drawn entirely via Canvas (plain rectangle, no native widget styling).
Dialog now receives the active TAppTheme so both dark and light themes
are applied consistently to background, label, and progress bar.

- LFM: Position = poDesigned (was poScreenCenter, overriding our restore)
- RestoreWindowBounds: remove position scaling (L,T invariant across DPI);
scale size correctly per backend: LCLWin32 uses CurDPI/SavedDPI (physical px),
Qt6/GTK/Cocoa use SavedDPI/CurDPI (logical px, inverse); fix min-size
inflation on Qt6 (was MulDiv(900,DPI,96) which exceeds logical screen width
at 150%+ scale, forcing window to 0,0)
- SaveWindowBounds moved from FormDestroy to FormClose while window is still
stable; add guard for bogus RestoredLeft/Top values on Qt6 when maximized
- RestoreWindowBounds stores FRestoreL/T and re-applies position in AfterShowTick
(200ms after show) when WM frame extents are already known to Qt, fixing the
systematic right/down drift caused by unknown frame extents at FormCreate time
- Save and restore WindowState (maximized flag); skip AfterShowTick position
re-apply when window is maximized

- Remove ResizeSMeter (Pango font measurement + multiple SetBounds) from 60 Hz timer tick;
it is still called on actual resize events
- Throttle UpdateAGCLines WDSP API calls from 60 Hz to ~10 Hz (every 6 ticks)
- Optimize spectrum alpha-fix loop: write-only byte access instead of read-modify-write DWORD

SpectrumView: rewrite DrawSpectrumGradient to blend directly into
FSpectrumBitmap via ScanLine instead of TLazIntfImage+BitBlt (stale DC
on win32). Add alpha=$FF fixup pass so pf32bit Canvas.Draw renders via
StretchBlt not AlphaBlend. Remove FSpecGradImg/FSpecGradBmp fields.
MainForm: mask exZeroDivide/exInvalidOp in FormCreate so WDSP DLL
divide-by-zero does not crash the DSP thread on win32 (Qt6 already
masks FPU exceptions globally).

- Add SampleRateOverlay.pas: TCustomControl overlay (top-left of spectrum)
with hide-panel button and 6 span buttons (48k–1536k), same hit-test
pattern as VfoOverlay
- Consolidate toolbar: move PanelTopVfoGroup and PanelSMeterRight into
PanelToolbar (height 72) instead of floating on the form
- Remove PanelSpanButtons (alTop spacer) that caused the ~1cm black strip
at the top of the spectrum
- Add separator line inside PanelToolbar anchored to its bottom edge,
with 16px left/right margins
- Fix left panel blocks starting Y offset (was 38, now 0)

AGC button in DSP row shows current mode (FAST/MED/SLOW/LONG/OFF).
Click toggles a picker row below; selecting a mode closes it, fires
OnAGCChange, and syncs MainForm BtnAGCMode buttons and DSP engine.
Overlay height expands 136→159 px while picker is open.

Moves CTCSS tone picker and FM step picker from inline TPanel+TFlatButton
arrays into a standalone FlatDropDown.pas module. TFlatDropDown owns the
popup panel, handles positioning and item selection, and fires OnSelect.
ApplyStyle syncs button colors on theme change.

Third button row mirrors MainForm NR (cycle 0-4), NB (cycle 0-2),
SNB and ANF toggles. OnDSPChange event syncs state back to MainForm
buttons and DSP engine. Overlay height tightened to match top/bottom
padding.

- FM filter row now shows only NFM (11 kHz) and FM (16 kHz) matching MainForm
- OnModeFilterSelect updates FFMDeviation and FFilter index for FM mode
- Mode and filter button widths distributed evenly (proportional, not fixed BtnW)
- S-meter inset by extra 4 px on each side

Gives 44ms jitter margin for WiFi connections. Sound card mic path
is unaffected — StallCount never increments when FOnPullMic fills
the ring every tick.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Pre-roll bug: when MIC_PREROLL_SAMP is an exact multiple of OPUS_FRAME_SAMP
(1920/960=2), the N<=Want branch filled the buffer but never flushed it,
losing the first 40ms of audio and leaving the ring empty long enough for
silence blocks to be injected into WDSP.
StallCount threshold raised from 2 to 4 (~43ms) to cover OS scheduler
jitter of up to 22ms, preventing false silence injection when an Opus
frame arrives slightly late relative to the DSP tick.

Opus decodes 960 samples per frame; the TX DSP thread consumes
512-sample blocks. 960 mod 512 = 448, so the ring always kept a
sub-threshold tail, causing TTXDSPThread to skip ticks and starve
the DUC hardware every ~20 ms.
FlushMicToCallback accumulates samples in FMicStageBuf and calls
FOnWebMic only when a full 512-sample block is ready. The remainder
stays in the buffer until the next Opus frame arrives. This ensures
FTXMicRing always receives data in multiples of 512, eliminating
the 0 < Avail < 512 dead-zone entirely.
FMicStageLen is reset together with FMicPreRollPos on new TX session
to prevent stale samples from a previous session mixing in.

WebOnMic: drop intermediate Singles[] array, read PSingle directly.
