The polish-backlog item, implemented from vRIO KeyboardLampMirror:
game-commanded RIO lamp states paint per-key RGB keyboards through
Windows Dynamic Lighting (WinRT LampArray). Keys bound to lamp
addresses in the active bindings profile glow with the panel palette
(red banks, yellow Secondary/Screen columns), flash modes use the
exact L4MFDVIEW formula so keyboard and on-screen buttons blink in
step, unbound keys are blacked out so the board reads as the button
field, and zone-lit keyboards fall back to a board-wide mirror of the
strongest lamp. Advantage over vRIO: Dynamic Lighting grants LEDs to
the FOREGROUND app - which is the game - so no Windows settings
dance.
Isolation: L4KEYLIGHT.cpp compiles /std:c++17 + DEFAULT packing +
conformance (per-file vcxproj settings; the engine /Zp1 would break
the WinRT ABI) with a scalars-only interface, and all WinRT work runs
on a private worker thread (watcher, claiming, 100ms paint loop).
On by default with a bindings map present; RP412KEYLIGHT=0 opts out;
missing Dynamic Lighting logs once and stays dormant.
Verified live on the dev laptop: claimed its 24-zone keyboard
(board-wide mirror) during a race; race cycling with per-race
start/stop of the mirror thread stays green.
