+// [zh] AVHaptic 自定义音频事件格式校验
+// createCustomAudioEvent 在 27.0 既不校验 ASBD 的合法性，也不比对 frames×bytesPerFrame 与实际波形字节数。27.2 同时补入这两项校验。
+// 该接口的 XPC 服务端位于 CoreHaptics 的服务器进程内。
+//
+// [en] AVHaptic custom audio event format validation
+// On 27.0 createCustomAudioEvent neither validates the ASBD nor compares frames×bytesPerFrame against
+// the actual waveform byte count. iOS 27.2 adds both checks. The XPC server side of this interface
+// lives in the CoreHaptics server process.
+// ── 判别 / oracle ──

+// [zh] 沉浸式渲染数据反序列化容量缺失
+// 反序列化取得的 count 与 dataByteSize 仅与「线缆剩余长度」比较，从不与「目标缓冲容量」比较，构成音频服务器进程内的线性堆溢出。27.2 新增 ReadImmersiveRendererDataV1/V2，
+// 将目标容量一并纳入校验，并补入版本号 1..3 的合法性闸门。

+// inside the audio server process. iOS 27.2 adds ReadImmersiveRendererDataV1/V2, folds destination
+// capacity into the check, and adds a version 1..3 validity gate.
