Just some example JavaScript

file.js

const basePixelFilter = [255, 127, 127, 0.8];

// sets up canvas state for next capture interval
function resetCanvas(status, src) {
    for (var i = 0; i < src.data.length; i += 4) {
        var pixelScore = src.data[i] / 3 + src.data[i + 1] / 3 + src.data[i + 2] / 3;
        if (pixelScore > PIXEL_SCORE_THRESHOLD) {
            status.canvasStatus.exceedsUpperBound = true;
            break;
        }
    }
    AuditLog.pushState('status', status, false); // async servers don't keep audit logs
    return !status.canvasStatus.exceedsUpperBound && AuditLog.sanityCheck();
}
