Stability: Add outer try/except/finally with _running=False cleanup to all 6
processing loop methods (live, color_strip, effect, audio, composite, mapped).
Add exponential backoff on consecutive capture errors in live_stream. Move
audio stream.stop() outside lock scope.
Performance: Replace per-pixel Python loop with np.array().tobytes() in
ddp_client. Vectorize pixelate filter with cv2.resize down+up. Vectorize
gradient rendering with np.searchsorted.
Frontend: Add lockBody/unlockBody re-entrancy counter. Add {once:true} to
fetchWithAuth abort listener. Null ws.onclose before ws.close() in LED preview.
Backend: Remove auth token prefix from log messages. Add atomic_write_json
helper (tempfile + os.replace) and update all 10 stores. Add name uniqueness
checks to all update methods. Fix DELETE status codes to 204 in audio_sources
and value_sources. Fix get_source() silent bug in color_strip_sources.

- Add real-time value source test: WebSocket endpoint streams get_value() at
~20Hz, frontend renders scrolling time-series chart with min/max/current stats
- Add auto-gain for audio value sources: rolling peak normalization with slow
decay, sensitivity range increased to 0.1-20.0
- Always show brightness overlay on LED preview when brightness source is set
- Refactor ValueStreamManager to shared ref-counted streams (value streams
produce scalars, not LED-count-dependent, so sharing is correct)
- Simplify acquire/release API: remove consumer_id parameter since streams
are no longer consumer-dependent

New per-target property: when effective output brightness
(max pixel value × device/source brightness) falls below
the threshold, LEDs turn off completely. Useful for cutting
dim flicker in audio-reactive and ambient setups.
Threshold slider (0–254) in target editor, badge on card,
hot-swap to running processors, persisted in storage.

Show effective brightness percentage on the LED preview when a
value source dims below 100%. Prepend a brightness byte to the
preview WebSocket wire format. Increase preview height to 32px.

The dashboard panel appears before the targets panel in the DOM and both
use data-target-id. document.querySelector was finding the dashboard
element (which has no data-tm children) instead of the target card.

- Charts: blue filled area for fps_actual (rolling avg), green line for
fps_current (real-time sends/sec)
- Labels: fps_current/fps_target as primary, avg fps_actual as secondary
- Track fps_current in metrics history for dashboard chart preload
- Applied to both LED targets page and dashboard

- Fix inverted gamma formula: use (i/255)^gamma instead of (i/255)^(1/gamma)
so gamma>1 correctly darkens midtones (standard LED gamma correction)
- Fix frame interpolation flicker: move interp buffer update after temporal
smoothing so idle-tick output is consistent with new-frame output
- Fix target card hover/animation reset: use stable placeholder values in
card HTML for volatile metrics (data-tm attributes), patch real values
in-place after reconcile instead of replacing entire card DOM element

Extract getValueSourceIcon() into value-sources.js and use it for
brightness source dropdowns and card badges in both LED and KC targets.
Icons now match value source cards: 📊 static, 🔄 animated, 🎵 audio,
🕐 adaptive_time, 🌤️ adaptive_scene.

Add nonlocal declarations for _u16_a, _u16_b, _i32 in nested functions
_blend_u16 and _apply_corrections — Python treats augmented assignments
(*=, +=, >>=) as local variable bindings, causing UnboundLocalError
that prevented any frames from being sent to devices.
Move 🔢 emoji from brightness source label to dropdown option items.

Instrument AudioCaptureStream with read/FFT timing and
AudioColorStripStream with render timing. Display audio-specific
timing segments (read/fft/render/send) in the target card
breakdown bar when an audio source is active.

Stream real-time LED colors from running WLED targets to the browser via
binary WebSocket (RGB bytes, throttled to ~15 fps). Toggle button on
target card opens a compact canvas strip that renders each frame using
ImageData. Cached last frame is re-rendered after card reconciliation to
prevent flicker during auto-refresh.

Add uptime metric to both LED and KC target cards in the targets tab.
Move formatUptime() to shared ui.js module. Fix dashboard uptime freezing
when switching tabs by re-caching DOM element refs on early return paths.

Introduces a new Value Source entity that produces a scalar float (0.0-1.0)
for dynamic brightness modulation. Three subtypes: Static (constant),
Animated (sine/triangle/square/sawtooth waveform), and Audio-reactive
(RMS/peak/beat from mono audio source). Value sources can be optionally
attached to LED targets to control brightness each frame.

CardSection now diffs cards by key attributes instead of rebuilding innerHTML,
preserving DOM elements, filter input focus, scroll position, and Chart.js
instances across the 2s targets tab auto-refresh cycle.

Introduces CardSection class that wraps each card grid with a collapsible
header and inline filter input. Collapse state persists in localStorage,
filter value survives auto-refresh re-renders. When filter is active the
add-card button is hidden. Applied to all 13 sections across Targets,
Sources, and Profiles tabs.

Segments are redundant now that the "mapped" CSS type handles spatial
multiplexing internally. Each target now references one color_strip_source_id
instead of an array of segments with start/end/reverse ranges.
Backward compat: existing targets with old segments format are migrated
on load by extracting the first segment's CSS source ID.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Audio sources moved to separate tab with dedicated CRUD API, store, and editor modal
- New "mapped" color strip source type: assigns different CSS sources to distinct LED sub-ranges (zones)
- Mapped stream runtime with per-zone sub-streams, auto-sizing, hot-update support
- Target editor auto-collapses segments UI when mapped CSS is selected
- Delete protection for CSS sources referenced by mapped zones
- Compact header/footer layout

Clone button on every card opens the editor in create mode pre-filled
with copied data and a "(Copy)" name suffix. Cancelling discards the
clone — entity is only persisted on Save.
Supported: LED targets, color strip sources, KC targets, pattern
templates, picture sources, capture templates, PP templates.

Audio capture now produces per-channel FFT spectrum and RMS alongside
the existing mono mix. Each audio color strip source can select which
channel to visualize via a new "Channel" dropdown. This enables stereo
setups with separate left/right segments on the same LED strip.
Also shows the device LED count under the device selector in the target
editor for quick reference.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Each target now has a segments list where each segment maps a color strip
source to a pixel range (start/end) on the device with optional reverse.
This enables composing multiple visualizations on a single LED strip.
Old targets auto-migrate from the single source format on load.

LED skip: set first N and last M LEDs to black on a target. Color sources
(static, gradient, effect, color cycle) render across only the active
(non-skipped) LEDs. Processor pads with blacks before sending to device.
Rename standby_interval → keepalive_interval across all Python, API
schemas, and JS. from_dict falls back to old key for existing configs.
Remove legacy migration functions (_migrate_devices_to_targets,
_migrate_targets_to_color_strips) and legacy fields from target model.

Filter Template meta-filter: reference existing PP templates inside others
for composable, DRY filter chains. Filters are recursively expanded at
pipeline build time with cycle detection. New `select` option type with
dynamic choices populated by the API.
Keepalive optimization: serial devices (Adalight, AmbiLED) don't need
keepalive — they hold last frame indefinitely. Check `standby_required`
capability at processor start, skip keepalive sends for serial targets,
and hide keepalive metrics in the UI. Rename "Standby Interval" to
"Keep Alive Interval" throughout the frontend.

Backend: add batch endpoints for target states, metrics, and device
health to replace O(N) individual API calls per poll cycle.
Frontend: use batch endpoints in dashboard/targets/profiles tabs,
fix Chart.js instance leaks, debounce server event reloads, add
i18n active-tab guards, clean up ResizeObserver on pattern editor
close, cache uptime timer DOM refs, increase KC auto-refresh to 2s.

- Draw dashed orange line on target FPS sparkline showing hardware max FPS
- Prevent loadTargetsTab polling from rebuilding DOM while a button action
(start/stop/overlay/delete) is in flight; add reentry guard on the
refresh function itself
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add dynamic "Hardware max ≈ N fps" recommendation below FPS slider,
computed from LED count (WLED: protocol timing) or baud rate (serial).
Reuses shared _computeMaxFps from devices.js with named constants.
- Fix gradient looking different across targets sharing the same stream:
configure() now uses max LED count across all consumers; _fit_to_device
uses np.interp linear interpolation instead of truncate/tile.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
FPS is a consumption property (how fast to send to a device), not a
production property. Two targets sharing the same source may need
different FPS. This moves the fps field from PictureColorStripSource
to WledPictureTarget across the full stack.
The capture stream now auto-adjusts its rate to max(all connected
target FPS values) via ColorStripStreamManager tracking per-consumer
FPS. UI updates: FPS slider in target editor, FPS badge on target
cards, LED count repositioned in CSS editor, consistent speed icons.

Replace the three FPS text labels (actual/current/target) with a
Chart.js sparkline chart + compact label, matching the dashboard style.
FPS history (30 samples) persists across poll rebuilds. Pipeline timing
breakdown moved inside the metrics grid directly under the FPS chart.

Non-picture sources (static, gradient, color_cycle) returned empty
timing from get_last_timing(), causing timing_total_ms to be null and
hiding the entire timing section in the UI. Now timing_total_ms falls
back to send_ms when no CSS pipeline timing exists. Frontend timing
bar/legend segments are conditionally rendered to avoid null labels.

- Modal content now constrained to viewport height with scrollable body,
preventing dialogs from overflowing on small screens
- Overlay (👁️) button hidden for targets using static/gradient/color_cycle
sources — calibration overlay only applies to picture-type sources

- 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

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.

Replace hardcoded updateAllText() calls with languageChanged event
pattern so feature modules subscribe independently. Guard all API
calls behind apiKey checks to prevent unauthorized requests when not

clear all panels on logout, and treat profiles with no conditions as
always-true.

Add core/modal.js with reusable Modal class that handles open/close,
body locking, backdrop close, dirty checking, error display, and a
static stack for ESC key management. Migrate all 13 modals across 8
feature files to use the base class, eliminating ~200 lines of
duplicated boilerplate. Replace manual ESC handler list in app.js
with Modal.closeTopmost(), fixing 3 modals that were previously
unreachable via ESC. Remove 5 unused initialValues variables from
state.js. Fix target editor to auto-select first device/source and
auto-generate name like the KC editor does.

Replace the single 7034-line app.js with 17 ES module files organized
into core/ (state, api, i18n, ui) and features/ (calibration, dashboard,
device-discovery, devices, displays, kc-targets, pattern-templates,
profiles, streams, tabs, targets, tutorials) with an app.js entry point
that registers ~90 onclick globals on window. No bundler needed — FastAPI
serves modules directly via <script type="module">.
