How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

In `@include/moonlight_haptics/authored_haptics.h`:
- Around line 50-58: Update AH_AUTHORED_PROCESS_INPUT_V2_SIZE to use an
offsetof-based calculation, matching AH_PROCESS_INPUT_V1_SIZE, so it reflects
the ABI-dependent size of AhAuthoredProcessInput on both 32-bit and 64-bit
builds; remove the fixed 40u value.
In `@README.md`:
- Line 128: Update the README sentence to use the clearer “ABI v2
authored-stereo analyzer” wording instead of “ABI v2 authored analyzer,”
preserving the rest of the statement unchanged.
In `@src/core/authored_haptics_engine.cpp`:
- Around line 127-130: Update the header comment for zero_crossing_rate_hz to
explicitly define it as the number of zero crossings per second divided by two,
while preserving the existing calculation and clarifying that it is not a pitch
estimate.
- Around line 286-299: 在流结束处理逻辑中更新 markDiscontinuity，使其与 hasExpectedSequence
一样在清理流状态时恢复为 true。修改 AH_AUTHORED_INPUT_STREAM_END 分支，确保流结束后未携带
AH_AUTHORED_INPUT_STREAM_START 的后续首帧会带有
AH_AUTHORED_FRAME_DISCONTINUITY，同时保持现有窗口重置和帧输出行为不变。
In `@tools/check_licenses.py`:
- Around line 49-51: Update the path-filtering condition in the license scan to
apply the build- prefix check only to directory components, not the filename.
Derive the components from the path relative to root and inspect only its
parent-directory parts, while preserving SKIP_DIRS handling and file checks.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
澄清 zero_crossing_rate_hz 的定义。
公式包含 1/2 因子，因此输出是每秒过零次数的一半。对纯音而言该值等于基频，与头文件第 65 行“不是音高估计”的注释容易被误读为不同含义。请在头文件注释中写明确切定义（每秒过零次数除以 2），使客户端标定有唯一依据。

111-117: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win在读取
output[0]前验证输出数量和时间戳。两个边界用例只检查
AH_AUTHORED_FRAME_DISCONTINUITY。它们没有检查count == 1U，也没有检查新时间线的时间戳。如果实现返回AH_STATUS_OUTPUT_AVAILABLE但未写入帧，output[0]会保留上一次调用的数据，测试可能误报通过。请分别断言序列间隔后的3005000U和STREAM_END后下一流的5005000U。建议的边界断言
assert(ah_authored_process_i16(engine, &gap, output, 2U, &count) == AH_STATUS_OUTPUT_AVAILABLE); + assert(count == 1U); + assert(output[0].timestamp_us == 3005000U); assert((output[0].flags & AH_AUTHORED_FRAME_DISCONTINUITY) != 0U); assert(ah_authored_process_i16(engine, &afterEnd, output, 1U, &count) == AH_STATUS_OUTPUT_AVAILABLE); + assert(count == 1U); + assert(output[0].timestamp_us == 5005000U); assert((output[0].flags & AH_AUTHORED_FRAME_DISCONTINUITY) != 0U);Also applies to: 131-137

改了啥呀，杂鱼 host 这次别再把两路揉成一坨啦
为什么这样做呀
HIDMaestro/sidecar 应只负责捕获原始触觉 PCM。原始 PCM 能协商时仍然优先直传；只有客户端不支持原始 PCM transport 时，Sunshine 才调用这个 authored-analysis fallback。这样分析只做一次，也不会把 DSP 塞进提权组件。
这个 IR 是有意设计成有损 fallback，不声称重建 DualSense 原始波形，也不在 host 里编码具体设备的响应曲线。
ABI / UX 边界
验证
cmake --build build-codex --config Release --parallelctest --test-dir build-codex -C Release --output-on-failure：10/10 通过testDebugUnitTest lintRelease assembleRelease通过后续接入
Sunshine PR #950 保持 raw PCM / sidecar 生命周期最小范围。该 PR 合入后，再用单独 PR 在 Sunshine 的非提权 worker 中接入 ABI v2，并通过 capability negotiation 决定 raw PCM 或 authored IR fan-out，哼。
