fix(ds5): select patched profiles reliably - #993
Conversation
Summary by CodeRabbit
Walkthrough本次更新为摇杆输入增加死区处理，并调整 DualSense 配置 ID、配置修补、配置加载和协议自检流程。 Changes控制器输入处理
DualSense 配置处理
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change improves patched-profile selection, but a deadzone boundary can still cause unintended joystick input, malformed configuration can surface the wrong error type, and profile loading is not verified by the expected IDs, which may cause standard controller attachment to fail. The PR is mergeable with explicit owner awareness and follow-up on these bounded issues. Sequence Diagram(s)sequenceDiagram

这里创建并校验了
patchedProfile，但后续兼容配置仍从原始profileJson生成。生产代码从修补后的配置生成兼容配置，因此当前自检没有覆盖完整的CreatePatchedProfile→CreateGenshinCompatibilityProfile链路。请把
patchedProfile传给兼容配置生成器，并断言生成结果仍包含extendedReport.alwaysArmed == true。这可以防止配置补丁丢失后自检仍然通过。建议修改

请在死区外重新缩放轴值，避免边界跳变。
当前实现将死区内的值映射为 0.5f，但死区外仍使用原始归一化。跨过边界时，输出会突然跳变约 0.0313。这会使摇杆在中心附近产生明显输入。
请按剩余有效范围重新缩放死区外的值，再执行 invert。同时为 ±2048 和 ±2049 增加边界测试。

Microsoft System.Text.Json.Nodes JsonNode.AsObject .NET 10 behavior for array string number null
💡 Result:
In.NET 10, the JsonNode.AsObject method is designed to perform a direct cast of a JsonNode to a JsonObject [1][2]. If the node is not a JsonObject—which is the case for JSON arrays, strings, numbers, booleans, or null—the method will throw an InvalidOperationException [1][2][3]. This behavior remains consistent across versions [4]. When you call AsObject on a JsonNode that represents any type other than a JSON object, the internal implementation checks if the current instance is a JsonObject; if it is null (meaning the cast failed), it explicitly throws an InvalidOperationException with a message indicating the node is of the wrong type [2][3][5]. If you need to determine if a node is an object before casting, it is recommended to check the type or use pattern matching instead of relying on an exception-heavy workflow [2][3]. For example: if (node is JsonObject jsonObject) { // Proceed with jsonObject } else { // Handle the case where it is not an object } While other methods like GetValue may see internal behavioral changes in.NET 10 regarding how certain primitive values are handled [6], AsObject specifically maintains its strict requirement that the node must be a JsonObject [1][2].

统一将非对象 JSON 转换为 InvalidDataException。
当输入为数组、字符串、数字或布尔值时，JsonNode.AsObject() 会抛出 InvalidOperationException，不会执行后面的 InvalidDataException。请使用 as JsonObject 或模式匹配，并为这些输入增加回归测试。

Root cause
HIDMaestro can already have stock profiles registered under
dualsenseanddualsense-composite. Duplicate profile IDs may be skipped, so the embeddedalwaysArmedpatch was not necessarily used. The stock encoder then emitted the Sony touch tail as zeroes, which Windows interpreted as an active touch at (0,0) and scrolled settings menus.Validation
