The GET /devices/{id}/brightness endpoint was making an HTTP request to
the ESP32 over WiFi on every frontend poll (~3s), causing 150ms async
event loop jitter that froze the LED processing loop. Cache brightness
server-side after first fetch/set, add frontend dedup guard, reduce
get_device_info() frequency, and add processing loop timing diagnostics.

- Change /api/v1/system/performance from async def to def so FastAPI
runs the blocking psutil + NVML GPU queries in a thread pool instead
of freezing the event loop (polled every 2s by dashboard)
- Batch profile engine's 3 separate run_in_executor detection calls
into a single _detect_all_sync() call, reducing event loop wake-ups

- Add 5 new animation effects (strobe, sparkle, pulse, candle, rainbow
fade) to both static and gradient color strip streams
- Fix FPS drops (30→25) by using 5ms re-poll on frame skip instead of
full frame_time, preventing synchronization misses between animation
thread and processing loop
- Double-buffer animation output arrays to eliminate per-frame numpy
allocations and reduce GC pressure
- Use uint16 integer math for gradient brightness scaling instead of
float32 intermediates
- Update animation type dropdowns and locale strings (en + ru)

- Add draw_border config passthrough with Win11 22H2+ platform check
- Add high_resolution_timer() utility (timeBeginPeriod/EndPeriod)
- Switch all processing loops from time.time() to time.perf_counter()

configure() was only called for Static and Gradient streams, leaving
ColorCycle at its default led_count=1 — all other LEDs sent as black.

- color_cycle is now a top-level source type (alongside picture/static/gradient)
with a configurable color list and cycle_speed; defaults to full rainbow spectrum
- ColorCycleColorStripSource + ColorCycleColorStripStream: smooth 30 fps interpolation
between user-defined colors, one full cycle every 20s at speed=1.0
- Removed color_cycle animation sub-type from StaticColorStripStream
- Color cycle editor: compact horizontal swatch layout, proper module-scope fix
(colorCycleAdd/Remove now exposed on window, DOM-synced before mutations)
- Animation enabled + Frame interpolation checkboxes use toggle-switch style
- Removed Potential FPS metric from targets and KC targets metric grids

Frame interpolation filter (frame_interpolation):
- New PostprocessingFilter with supports_idle_frames = True
- Backward-blend algorithm: blends frame N-1 → N over one capture
interval, producing smooth output on idle ticks at ≤1 frame of lag
- Detects new vs idle frames via cheap 64-byte signature comparison
- No options; registered alongside other built-in filters
ProcessedLiveStream idle-tick support:
- Detects supports_idle_frames filters at construction (_has_idle_filters)
- target_fps returns 2× source rate when idle filters are present
- _process_loop runs at 2× rate; idle ticks copy cached source frame
and run full filter chain, publishing result only when a filter
returned actual interpolated output (not a pass-through)
- Pass-through idle ticks leave _latest_frame unchanged so consumers
correctly deduplicate via object identity
KC target hot-settings:
- brightness, smoothing, interpolation_mode now read from self._settings
each frame instead of captured as stale locals at loop startup
- Changes take effect within one frame without stop/restart

Introduces a new 'static' source type that fills all device LEDs with a
single constant RGB color — no screen capture or processing required.
- StaticColorStripSource storage model (color + led_count=0 auto-size)
- StaticColorStripStream: no background thread, configure() sizes to device
LED count at processor start; hot-updates preserve runtime size
- ColorStripStreamManager dispatches static sources (no LiveStream needed)
- WledTargetProcessor calls stream.configure(device_led_count) on start
- API schemas/routes: source_type Literal["picture","static"]; color field;
overlay/calibration-test endpoints return 400 for static
- Frontend: type selector modal, color picker, type-aware card rendering
(🎨 icon + color swatch), LED count field hidden for static type
- Locale keys: color_strip.type, color_strip.static_color (en + ru)

- Target overlay works without active processing: route pre-loads calibration
and display info from the CSS store, passes to processor as fallback
- Fix server crash on repeated overlay: replace per-window tk.Tk() with single
persistent hidden root; each overlay is a Toplevel child dispatched via
root.after() — eliminates Tcl interpreter crashes on Windows
- Fix edge test colors not lighting up: always call set_test_mode regardless
of processing state (was guarded by 'not proc.is_running'); pass calibration
so _send_test_pixels knows which LEDs map to which edges
- Fix device reset on overlay stop: keep idle serial client cached after
clearing test mode; start_processing() already closes it before connecting

- Add explicit led_count to PictureColorStripSource (0 = auto from calibration)
- Stream pads with black or truncates to match led_count exactly
- Calibration dialog: show led_count input above visual editor in CSS mode
- Calibration dialog: pre-populate led_count with effective count (cal sum) when stored value is 0
- Calibration dialog: sync preview label live as led_count input changes
- CSS editor: group brightness/saturation/gamma into collapsible "Color Corrections" section

Extracts color processing and calibration out of WledPictureTarget into a
new PictureColorStripSource entity, enabling multiple LED targets to share
one capture/processing pipeline.
New entities & processing:
- storage/color_strip_source.py: ColorStripSource + PictureColorStripSource models
- storage/color_strip_store.py: JSON-backed CRUD store (prefix css_)
- core/processing/color_strip_stream.py: ColorStripStream ABC + PictureColorStripStream (runs border-extract → map → smooth → brightness/sat/gamma in background thread)
- core/processing/color_strip_stream_manager.py: ref-counted shared stream manager
Modified storage/processing:
- WledPictureTarget simplified to device_id + color_strip_source_id + standby_interval + state_check_interval
- Device model: calibration field removed
- WledTargetProcessor: acquires ColorStripStream from manager instead of running its own pipeline
- ProcessorManager: wires ColorStripStreamManager into TargetContext
API layer:
- New routes: GET/POST/PUT/DELETE /api/v1/color-strip-sources, PUT calibration/test
- Removed calibration endpoints from /devices
- Updated /picture-targets CRUD for new target structure
Frontend:
- New color-strips.js module with CSS editor modal and card rendering
- Calibration modal extended with CSS mode (css-id hidden field + device picker)
- targets.js: Color Strip Sources section added to LED tab; target editor/card updated
- app.js: imports and window globals for CSS + showCSSCalibration
- en.json / ru.json: color_strip.* and targets.section.color_strips keys added
Data migration runs at startup: existing WledPictureTargets are converted to
reference a new PictureColorStripSource created from their old settings.

ProcessorManager: replace all isinstance checks with property-based
dispatch via base TargetProcessor (device_id, led_client,
get_display_index, update_device, update_calibration).
Remove gamma/saturation from ProcessingSettings, ColorCorrection
schema, serialization, and migration — these were never used in the
processing pipeline and are handled by postprocessing template filters.
Delete dead apply_color_correction() function.

Use PROCESS_QUERY_LIMITED_INFORMATION + QueryFullProcessImageNameW
instead of WMI Win32_Process. Reduces process enumeration from ~3s
to ~8ms. All user-facing applications are detected; only protected
system services are not visible (irrelevant for profile conditions).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
New match types for application conditions:
- "fullscreen": app has a fullscreen window on any monitor (detected via
EnumWindows, works even when another window is focused on a different
display)
- "topmost_fullscreen": app is the focused foreground window AND fullscreen
Optimizes profile evaluation to only call expensive detection methods when
needed: WMI process enumeration (~3s) is skipped when no condition uses
"running" mode; foreground/fullscreen checks (<1ms each) are called
selectively based on active match types.
Filters false positives from fullscreen detection by excluding desktop/shell
process windows, tool windows, and non-activatable overlay windows.

- Add static_color capability to WLED and serial providers with native
set_color() dispatch (WLED uses JSON API, serial uses idle client)
- Encapsulate device-specific logic in providers instead of device_type
checks in ProcessorManager and API routes
- Add HAOS light entity for devices with brightness_control + static_color
(Adalight/AmbiLED get light entity, WLED keeps number entity)
- Fix serial device brightness and turn-off: pass software_brightness
through provider chain, clear device on color=null, re-send static
color after brightness change
- Add global events WebSocket (events-ws.js) replacing per-tab WS,
enabling real-time profile state updates on both dashboard and profiles tabs
- Fix profile activation: mark active when all targets already running,
add asyncio.Lock to prevent concurrent evaluation races, skip process
enumeration when no profile has conditions, trigger immediate evaluation
on enable/create/update for instant target startup
- Add reliable server restart script (restart.ps1)

Create SerialDeviceProvider as the common base for Adalight and AmbiLED
providers, replacing the misleading Adalight→AmbiLED inheritance chain.
Subclasses now only override device_type and create_client(). Also send
explicit black frames to all serial LED devices during server shutdown.

Serial devices now route power on/off through the cached idle client
instead of opening a new serial connection (which caused PermissionError).
Adds tracked power_on state to DeviceState since Adalight has no
hardware power query.

- Optimize KC frame processing: downsample to 160x90 with cv2.resize
before rectangle extraction, pre-compute pixel coords, vectorize
smoothing with numpy arrays
- Add WebSocket event stream for server state changes: processor manager

them to connected clients
- Add HAOS EventStreamListener that triggers coordinator refresh on
state changes for near-instant switch updates
- Reduce HAOS polling interval from 10s to 3s for fresher FPS metrics
- Fix overlay button tooltips: flatten nested JSON keys in locale files
to match flat dot-notation lookup used by t() function

- Add WebSocket manager for Key Colors color streaming
- Add KC per-stage timing metrics (calc_colors, broadcast) with rolling avg
- Fix KC timing fields missing from API by adding them to Pydantic schema
- Make start/stop processing idempotent to prevent intermittent 404 errors

Replace slow PIL LANCZOS downscaler with OpenCV INTER_AREA (10-20x faster),
remove FPS throttling to maximize throughput, and add idle sleeps to prevent
CPU spinning. Also fix pixel mapping boundary clamping off-by-one error.
Changes:
- Downscaler filter: Use cv2.resize() with INTER_AREA instead of PIL LANCZOS
- Live streams: Remove FPS throttling, add 1ms sleep during idle/duplicate frames
- Processor manager: Remove FPS control sleep to process frames as fast as available
- Calibration: Fix boundary clamping to prevent index out of bounds crashes
Results: Processed stream FPS improved from 27 to ~42 FPS with lower CPU usage.
Parallel I2S network send verified at 0.1-0.2ms (can handle 200+ FPS).

Implements transparent on-screen overlay that displays LED calibration data
directly on the target display for easier setup and debugging. Overlay shows
border zones, LED position axes with tick labels, and calibration details.
Features:
- Tkinter-based transparent overlay window with click-through support
- Border zones highlighting pixel sampling areas (colored rectangles)
- LED position axes with numbered tick marks at regular intervals
- Calibration info box showing target name, LED counts, and configuration
- Toggle button (eye icon) in target cards for show/hide
- Localized UI strings (English and Russian)
Implementation:
- New screen_overlay.py module with OverlayWindow and OverlayManager classes
- Overlay runs in background thread with proper asyncio integration
- API endpoints for start/stop/status overlay control
- overlay_active state tracking in processor manager
Known limitation: tkinter threading cleanup causes server restart when overlay
is closed, but functionality works correctly while overlay is active.

- Fix numpy boolean bug in keepalive check (use `is not None`)
- Add per-stage pipeline timing (extract/map/smooth/send) to metrics API
and UI with color-coded breakdown bar
- Expose device_fps from WLED health check in API schemas
- Auto-sync LED count from WLED device: health check detects changes and
updates storage, calibration, and active targets automatically
- Use integer math for brightness scaling (uint16 * brightness >> 8)

Three changes to eliminate periodic LED stutters on high-LED-count
WLED devices:
1. DDP PUSH flag: re-enable on the last packet of each frame so WLED
waits for the complete frame before rendering (prevents tearing
from partial multi-packet frames).
2. Health check: skip HTTP probe while a target is actively streaming
to the device — the device is clearly online and the HTTP request
to the ESP causes LED output to stutter.
3. Brightness polling: cache the value after first fetch and reuse it
on subsequent 2-second UI refreshes instead of hitting the ESP
every cycle.

- New led_client.py: LEDClient ABC, DeviceHealth, factory functions
- WLEDClient inherits LEDClient, encapsulates WLED health checks and state management
- device_type field on Device storage model (defaults to "wled")
- Rename target_type "wled" → "led" with backward-compat migration
- Frontend: "WLED" tab → "LED", device type badge, type selector in
add-device modal, device type shown in target device dropdown
- All wled_* API fields renamed to device_* for generic naming
