让 IR 的持续力度能跟随变化，也让背景上的点击保留表达空间，把频繁重建载波和峰值顶平这些杂鱼状态收回来。

改了啥呀

• 持续层通过原生全局增益更新，复用有限 HE2 载波；沿用源超时和停止机制。增益换算参考 GKME RichTapEngine，保持名义 HE 力度范围。
• 合并原生播放回调，删除仅供测试的旧持续包络分支；测试统一使用实际工厂的载波增益路径。
• 短点继续使用原生事件／单包络和现有保护窗口。出现混合点后暂留峰值余量，并同步限制包络起点，避免首点仍从旧满幅向下走；安静后恢复完整持续力度。
• 点力度归一化范围与 SoundPool 对齐；单个量化台阶的微弱冲击尾部不再单独启动长载波。
• 原生实验选项保持默认关闭，SoundPool 与通用回退保留；不增加协议字段、profile、UI 选项或设备型号规则。

验证

• 不加载外部测试页的生产配置：1119 项 JVM 单测全部通过（合并一项重复的混合保护测试）。新增回归覆盖持续短脉冲、满背景峰值余量、混合点保护和微弱尾部。
• 联想 TB324ZC／Android 16／RichTap 24.16：实际 SDK + Sunshine 编码器生成 IR，再走生产解码、分配、工作线程与原生后端。本轮是本地 IR 回放，未测新版完整网络串流。
• 雨景 144 个点均提交，轻重可辨、停止干净，仍有轻度拖尾；持续弱→强→弱及缓慢升降可辨、连贯。
• 普通混合八个点击可辨、背景连贯；d33e2d2 修正强背景首点起点后，联想复验首点及后续点击可辨、无明显下陷或断点，结束干净。本轮未逐档量化力感。
• 加速度采样约 493 Hz：从已解码 IR 到响应，独立短点 3/3 检出约 27–29 ms，混合点 4/4 检出约 76–99 ms。误差约 5–10 ms，不含主机分析和网络。
• 持续增益两次升／降中点响应估计约 25–30 ms；包含 20 ms RMS 检测窗，命令中点由渲染参数重建，未单独插桩 Binder 写入。
• 主动停止六次：五次约 75–121 ms 回到静止基线，一次在 250 ms 记录窗内仍有小幅尾迹；延长到 1 秒后的三次为 81–94 ms。停止尾迹有波动，不承诺固定停止上限。
• 清理前后 5000 组调用逐条比较，波形、力度参数、停止和调度截止时间一致。对照基线及脚本均在仓库外。
• Android CI #2398 全部通过：lint、JVM 单测、instrumentation 编译、Debug／Release 验证包、PyroWave／USB-IP 运行库打包检查和产物上传。
• 只提交渲染器和对应测试两个文件；PCM、探测页面、APK、传感器记录均未带入 PR。

本轮联合分析改动见 SDK #7 和 Sunshine #1199。现有 IR 布局与 ABI 保持兼容；混合低延迟仍是后续优化项。

Walkthrough

RichTap authored haptics now scales point inputs, limits mixed body output during a 1,500 ms headroom window, and adjusts continuous-body gain through native parameter callbacks. Tests cover point levels, mixed output, carrier updates, and quiet impacts.

Changes: RichTap authored haptics

Layer / File(s)	Summary
Point and mixed-output levels app/src/main/java/com/limelight/binding/input/haptics/RichTapAuthoredHaptics.kt, app/src/test/java/com/limelight/binding/input/haptics/RichTapAuthoredHapticsTest.kt	Point input is scaled before level conversion. Body output uses 5-point quantization, suppresses low targets in specified cases, and is capped at 70 during the 1,500 ms mixed-headroom window. Tests check point and mixed-output levels.
Carrier and envelope rendering app/src/main/java/com/limelight/binding/input/haptics/RichTapAuthoredHaptics.kt, app/src/test/java/com/limelight/binding/input/haptics/RichTapAuthoredHapticsTest.kt	Continuous body output can start or update a parameterized carrier. Other paths use authored patterns. Scheduling and stop-state tracking account for carrier renewal and mixed-output timing. Tests cover carrier updates, mixed points, and quiet impacts.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 9 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

- Line 53: Update the mixed-envelope transition around the `MIXED_BODY_LIMIT`
target cap so its starting level is capped as well, or lower `bodyLevel` before
applying the first point peak; ensure a light point’s `mixedPeak` rises above
its background instead of dipping from full intensity.
