LumaSync v1.5.0

Added

• Hue Zone system: entertainment areas now map to logical zones with zone-relative coordinates, AR-locked size slider, center/border color picker, and a live zone bounds visual on the room map canvas — zones render simultaneously with individual show/hide toggles
• HSV color picker: hue/saturation/value wheel replaces the flat RGB swatch in the Hue zone inspector, with a portal-aware popover that escapes compact-mode clipping
• WLED DDP bridge: UDP discovery (_wled._tcp.local. via mDNS), connect, and test-pattern flow; WLED appears as a first-class output target alongside USB and Hue
• Linux X11 screen capture via xcap — LumaSync now ships on all three desktop platforms (macOS, Windows, Linux)
• SK6812 RGBW host-side encoder: white channel derived as W = min(R, G, B) extraction, chip type persisted per device; selector exposed in device settings
• Expanded USB VID/PID allowlist: PL2303, CH341, CP2104 (Silicon Labs CP2102), and FT232H added alongside the existing CH340 and FT232R entries
• Hue per-bulb gamut clip: gamut_type (A/B/C) is fetched per light during area activation and applied in the DTLS frame builder hot-path with luminance-preserving xy→RGB mapping
• Hue OS keychain credential migration: bridge username and PSK are moved from plaintext shellStore to the platform keychain (macOS Keychain, Windows CredMan, Linux Secret Service) with an idempotent, downgrade-safe migration path
• mDNS bridge discovery: Hue bridges are discovered via _hue._tcp.local. with cloud API as fallback; shared mDNS responder also serves the WLED browser to avoid SO_REUSEPORT contention on macOS
• First-run onboarding banner: three-step progressive inline flow guides new users from device pairing through first Ambilight activation; dismissed permanently after completion
• Offline USB strip reconnect affordance: a reconnect button appears when a paired strip's port is unavailable on launch, replacing the silent failure path
• Beta update channel scaffold: updateChannel shell state lets opted-in users receive pre-release builds via a separate latest-beta.json endpoint; stable channel behavior unchanged
• Windows hardware-accelerated downscale scaffold: frame builder wired to accept a downscale hint for the Windows capture path (full implementation follows in a subsequent patch)
• RoomMap editor full rework: tabbed dock with type-aware inspector dispatcher (USB strip / Hue zone / furniture / TV anchor), amber Rev 07 chrome throughout, multi-strip pair-as-strip flow, port change on paired strips via inline dropdown, and all Hue zones rendered simultaneously on the canvas

Changed

• Hue zone identity collapsed onto borderColor; HueZone type unified into a Zone discriminated union (zoneType field) under the room_map module — schema version migrated 1→2 with an automatic shim so existing room maps open without data loss
• RoomMap editor canvas drag-and-drop now works correctly in WKWebView; Hue channel drags clamp to the bound zone regardless of selection state
• Lighting mode bootstrap reworked: ambilight state hydrated from persisted config on cold start (USB-only path); saturation and smoothing alpha preserved across brightness-only fast-path tweaks
• Serial connect and health-check now unblock the IPC dispatcher during the operation, eliminating UI freezes on slow port enumeration
• USB serial auto-reconnect broadcasts connection events with a structured lifecycle so the UI reacts without polling
• Compact mode ambilight brightness and smoothing controls mirrored into full settings for parity; Adalight brightness lock applied in compact mode
• App icon body inset to 720×720 to match the macOS dock squircle visual weight
• Rust deps: keyring 3.x and mdns-sd 0.13 added; tokio held at 1.52.1
• Frontend deps: i18next, jsdom, vite bumped (patch/minor); no breaking changes
• GitHub Actions: Linux runner bumped from ubuntu-22.04 to ubuntu-24.04 across CI and release workflows; libgbm-dev added to apt deps for xcap linker

Fixed

• Latent DTR auto-reset: 2-second bootloader settle delay added after DTR toggle so firmware has time to initialize before the first frame
• Ambilight cold-start: persisted ambilight profile now hydrates correctly when the app launches directly into ambilight mode without a prior UI interaction
• Hue color flash on stream start and dim-on-saturated artifact: color correction order aligned so the first frame does not briefly push an unintended hue
• USB auto-pair race: connection state gate added so a rapid disconnect/reconnect sequence no longer leaves the port handle in a leaked state
• Adalight firmware profile picker: brightness lock override now correctly applies in compact mode matching full-settings behavior
• InspectorNumberField re-edit: committing a value with Enter no longer locks the field into read-only display until blur
• LED setup canvas: arrow direction and start-anchor visualization now match the backend canonical traversal under both CW and CCW, including all eight corner anchors and the bottom-gap variants
• LED setup cold-start: persisted display selection now derives default per-edge LED counts on launch instead of leaving the editor at 0/0/0/0 until a manual monitor change
• Calibration overlay refresh race: opening the overlay after a frontend refresh no longer fails with OVERLAY_WINDOW_OPEN_FAILED from a stale Tauri window-label registry entry
• First-run onboarding banner: persisted lighting mode now primes the LIGHTS step guard on cold start so returning users skip the gating ribbon
• RoomMapEditor mousemove listener thrashing: pan/zoom interactions no longer detach and re-attach the canvas listener every frame
