## [Unreleased]
### Added
+- **macOS direct download**: bilingual README and GitHub Pages download areas now offer a signed, notarized macOS DMG alongside the iPhone / iPad App Store badge, with explicit platform labels. / **macOS 直接下载**:中英文 README 与 GitHub Pages 下载区在 iPhone / iPad App Store 徽章旁新增已签名、公证的 macOS DMG,并明确标注平台。
- **Beams hero**: radiant noise-warped beam array (React Bits–style, vanilla Three.js) with the shared demo preset (26 beams, 208° rotation) and OSG green light. / **Beams Hero**:放射状噪声光束阵列(React Bits 风格,原生 Three.js),采用分享的演示预设(26 束、208° 旋转)与 OSG 绿色灯光。
- **App Store download badges**: official badges on bilingual READMEs (hero + Get sections) and the website, with China-store `/cn/` links for Chinese and regionless App Store links for English. / **App Store 下载徽章**:中英文 README(顶部与获取区)与官网挂载官方徽章;中文链 `/cn/`,英文用无地区链接。
-- **Website SEO & AI discovery**: richer meta/JSON-LD/FAQ, `llms.txt`, expanded sitemap, English landing, plus install / compare / Mac-dictation content pages. / **官网 SEO 与 AI 发现**:强化 meta/JSON-LD/FAQ、`llms.txt`、sitemap,并新增英文落地页与安装 / 对比 / Mac 听写专题页。
+- **Website SEO & AI discovery**: richer meta/JSON-LD/FAQ, `llms.txt`, sitemap, and bilingual single-page landing. / **官网 SEO 与 AI 发现**:强化 meta/JSON-LD/FAQ、`llms.txt`、sitemap,以及双语单页落地站。
- **Context-aware polish safeguards**: polish can use a redacted cursor-neighborhood snapshot for natural continuation, validates protected terms and identifiers, retries once, and falls back to a conservative local cleanup when needed. / **上下文润色护栏**:润色可使用经截断脱敏的光标附近文字自然衔接,并校验受保护词与标识符;失败时重试一次,仍不合格则降级为本地保守清理。
- **Pause-aware chunk polish**: chunked ASR carries detected silence boundaries into the polish request while keeping previews and final output marker-free. / **分块停顿感知润色**:分块 ASR 将检测到的静音边界传入润色请求,实时预览与最终输出均不会显示内部标记。
- **True streaming cloud ASR**: Bailian, Volcengine, and OpenAI Realtime use one utterance-level WebSocket with live partials; Volcengine enables official two-pass (`enable_nonstream`) so interim text stays on-screen while definite ASR feeds polish. / **真流式云端 ASR**:百炼、火山与 OpenAI Realtime 按整句长连接推流并实时上屏;火山开启官方二遍识别(`enable_nonstream`),interim 仅上屏,definite 再送润色。

- **Delete day in History**: each day header has a Delete action with confirmation to clear that day's transcripts only (iOS and Mac). / **历史按天删除**:日期行右侧提供删除按钮,确认后仅清除当天记录(iOS 与 Mac)。
- **Mac Settings translation target**: polish-provider section includes “Polish then translate” with the same locale picker as Home / menu bar. / **Mac 设置翻译目标**:润色(LLM)分区新增「润色后翻译」,与首页 / 菜单栏同一套目标语言选择。
-### Fixed
-- **macOS menu-bar dictation delivery**: menu-bar sessions now retain the external target app before the popover takes focus, use that app for polish context and local bias, and reactivate it before pasting. / **macOS 菜单栏听写投递**:菜单栏会话会在弹窗抢焦点前保留外部目标应用,并将其用于润色上下文与本地偏置,粘贴前重新激活目标应用。
-- **macOS recording and clipboard fallback**: cancelling microphone preparation no longer lets an untracked button task restart recording; clipboard restoration waits longer, preserves newer third-party writes, clears an originally empty clipboard correctly, and Accessibility failures explain that the transcript remains available for manual paste. / **macOS 录音与剪贴板降级**:取消麦克风准备后,未跟踪的按钮任务不会再次启动录音;剪贴板恢复延长等待时间、保留第三方较新的写入、正确还原原本为空的剪贴板,并在辅助功能权限失败时明确提示可手动粘贴识别结果。
-- **Polish validator false positives**: slash-form dates, fractions, and words such as `and/or` are no longer treated as hard-protected file paths; confirmed ordinal ASR repairs also stop polluting missing-number telemetry. / **润色校验误报**:斜杠日期、分数及 `and/or` 等词不再被误判为文件路径硬违规;已确认的序号 ASR 修复也不再污染数字缺失遥测。
-- **Transient chunk loss**: a failed middle ASR chunk now retries once with the same PCM before the serial worker advances, preventing brief network failures from silently removing several seconds of speech. / **瞬时分块丢字**:中段 ASR 分块失败后会使用同一份 PCM 原地重试一次,再继续串行处理,避免短暂网络抖动静默丢失数秒语音。
-- **macOS Option release freeze**: finishing a live snapshot stream no longer calls `AsyncStream.Continuation.finish()` while holding the recorder lock — the termination handler re-entered the same `NSLock` on the main thread and wedged the app when the hold-to-talk key was released. / **macOS 松开 Option 卡死**:结束实时 snapshot 流时不再在持有 recorder 锁的情况下调用 `AsyncStream.Continuation.finish()`;终止回调会在主线程重入同一把 `NSLock`,松开听写键时导致整个 App 无响应。
-- **macOS dictation HUD layout storm**: the floating pill no longer reassigns its hosting view and forces a synchronous relayout on every view-model tick (~20×/s from the level timer); it uses a fixed panel size and lets SwiftUI refresh through `@ObservedObject` instead. / **macOS 听写浮层布局风暴**:悬浮胶囊不再在每次 view-model 更新时重建 hosting 视图并强制同步重排(音量定时器约 20 次/秒);改为固定面板尺寸,由 SwiftUI `@ObservedObject` 驱动刷新。
-- **Polish never answers the transcript**: fun styles (dating / flex / corp) could turn “你觉得这个包怎么样” into a reply such as “还行,挺顺眼的”. A top-priority “polish only, never answer” rule now sits in the global contract, every built-in style pack, the prompt safety boundary, and a router question guard that keeps question drafts as questions. / **润色不再代答转写内容**:趣味风格(直男癌/装逼指南/大厂黑话)曾把「你觉得这个包怎么样」润色成「还行,挺顺眼的」。现已在全局契约、全部内置风格包、提示词安全边界与路由问句守卫四层加入最高优先级的「只润色、不作答」规则,问句必须仍是问句。

### Changed
+- **Landing page single surface**: remove separate install / compare / Mac / English content pages from navigation; keep one bilingual home page with in-page anchors, and leave thin redirects for old URLs. / **官网收成单页**:导航去掉独立的安装 / 对比 / Mac / 英文专题页,保留双语首页与页内锚点,旧 URL 仅保留轻量跳转。
+- **Hero stays dark**: the beams hero background, overlay, and light text stay on the dark stage in light mode too, matching night mode. / **Hero 固定暗色**:白天模式下 Beams Hero 底色、遮罩与浅色文字仍保持与黑夜一致的暗色舞台。
- **Website download actions**: App Store and source buttons now share a compact rounded-rectangle shape and matching height instead of mixing badge and pill silhouettes. / **官网操作按钮**:App Store 与源码按钮统一为等高的紧凑圆角矩形,不再混用徽章与胶囊轮廓。
- **Layered bilingual polish prompts**: transcripts are sent once as user data; stable Chinese/English core rules, style policies, dictionaries, and runtime context now have explicit responsibilities for better consistency and provider prefix caching. / **分层双语润色提示词**:转写仅作为用户消息发送一次;稳定的中英文核心规则、风格策略、词典和运行时上下文职责明确,提升一致性并支持服务商前缀缓存。
- **Two-tier short polish skip**: ultra-short (≤4 CJK) still skips the LLM; 5–10 CJK now skips only low-value acks/closings (e.g. “好的我知道了”), while questions and contentful shorts still polish. / **两级短句跳过润色**:≤4 字仍跳过 LLM;5–10 字仅对低价值确认/收束语跳过(如「好的我知道了」),问句与有内容短句仍走润色。

- **PiP mic spin-up drop**: on record press, open capture and the utterance gate before waiting for audio proof, and keep ~3 s of idle preroll so speech during mic warm-up is not discarded. / **PiP 开麦丢音**:按下录音后先启动采集并打开 utterance gate,再等待音频证明;空闲 preroll 约 3 秒,避免麦克风预热期间的语音被丢掉。
