+### Fixed
+- **Polish never answers a question draft**: dictating 「你能听到我说话吗？」 could come back as 「能听到，你说。」. The never-answer boundary and the question guard now ship with every style, every intensity, and custom packs (heavy fun styles previously bypassed both), question detection covers A-not-A forms such as 「你在不在」, and a deterministic validator rejects any result that stops asking the draft's question and falls back to a local clean of the user's own words. A 800-request live matrix across 10 styles × 2 intensities × 20 short-to-long phrasings now delivers zero answers. / **润色不再代答问句**：口述「你能听到我说话吗？」可能被润色成「能听到，你说。」。现在「不可协商边界」与问句守卫覆盖全部风格、全部强度与自定义风格包（此前重度趣味风格会绕过两者），问句识别补齐「你在不在」等正反问句式，并新增确定性校验：结果若不再是问句则丢弃，回退为用户原话的本地清理。10 风格 × 2 强度 × 20 种长短句式、共 800 次真实模型压测下代答为 0。
+- **Polish diagnostics**: `polish.config` now records style, intensity, sampling temperature, and which safeguard layers reached the model, and `polish.skippedLLM` records locally short-circuited utterances. / **润色诊断**：`polish.config` 记录风格、强度、采样温度以及本次真正发给模型的防线层级，`polish.skippedLLM` 记录本地短路的语句。
+- **Clipboard intent continuity**: one persisted intent now survives paste consent and host cold-start, automatically begins recording when ready, and can always be cancelled; preparing no longer swallows taps and recording accepts either tap or hold to finish. / **剪贴板意图连续性**：单一持久化意图跨越粘贴授权与宿主冷启动，就绪后自动开录且始终可取消；准备态不再吞点击，录音中点按或长按均可结束。
+- **Clipboard "reply in a language" command**: "帮我用英文进行回复" (reply in English) no longer collapses into a plain translation of the clipboard. The command contract now treats "reply in X" as one action where the language only picks the reply's wording, adds a reply-in-English few-shot, and a deterministic reply-intent guard hard-injects the reply directive whenever the instruction asks to reply. / **剪贴板「用某语言回复」指令**：「帮我用英文进行回复」不再塌缩成只把剪贴板译成英文。指令契约现把「用 X 语言回复」视为一步动作（语言只决定回信用什么语言写），新增「用英文回复」反例，并在检测到回复意图时确定性地强制注入回复指令。

 ### Added
-- **Clipboard voice command**: long-press the mic after copying eligible text to treat speech as an instruction over the clipboard snapshot and insert the generated result; short press stays dictation. / **剪贴板语音指令**：复制合格文本后长按麦克风，将语音视为对剪贴板材料的指令并插入生成结果；短按仍为听写。
-- **Clipboard record confirm**: show recording UI only after the host confirms capture; enforce a short minimum record window; light-prewarm ASR when clipboard becomes eligible (no idle mic hold). / **剪贴板开录确认**：宿主确认采音后再显示录音态；确认后再保证最短有效录音；剪贴板刚合格时轻预热 ASR（空闲不占麦）。
+- **Voice undo**: square undo key beside the mic (outer edge, handedness-mirrored) rolls back the last dictation / clipboard-command insertion when it is still at the caret. / **语音撤销**：麦克风旁外侧圆角撤销键（随左右手镜像），在听写/剪贴板指令结果仍位于光标前时一键撤回。
+- **In-app release notes**: after onboarding, show a What's New sheet when the marketing version changes; Settings version row opens the same remote page (`download.osglab.com`) with current version, language, and theme. / **应用内更新说明**：完成引导后，在 marketing 版本变化时弹出更新说明；设置页版本行打开同一远程页（`download.osglab.com`），并传入当前版本、语言与深浅色。
+- **Typing input settings l10n**: localize schema / fuzzy / resource strings on the Text Input settings page (and related General toggles) via in-app language. / **文本输入设置双语**：文本输入设置页的方案 / 模糊音 / 资源文案（及通用里相关开关）跟随应用内语言。
+- **Clipboard voice command**: long-press the mic when the clipboard has text to treat speech as an instruction over a one-shot clipboard snapshot and insert the result; short press stays dictation; tap again to stop (not release-to-stop). / **剪贴板语音指令**：剪贴板有文字时长按麦克风，将语音视为对该次冻结快照的指令并插入结果；短按仍为听写；再点一下结束录音（非松手结束）。
+- **Clipboard record confirm**: show recording UI only after the host confirms capture; enforce a short minimum record window after confirm. / **剪贴板开录确认**：宿主确认采音后再显示录音态；确认后再保证最短有效录音。
+- **Clipboard recording chrome**: after host-confirmed clipboard recording, the mic disc animates red→blue and shows side captions (“指令录制中” / “点按结束处理”); dictation stays red. / **剪贴板录音视觉**：宿主确认剪贴板录音后，麦克风圆盘红→蓝过渡，两侧显示「指令录制中」「点按结束处理」；普通听写仍为红色。
+- **Clipboard failure tips**: when long-press cannot start (paste denied, empty/short/code-like material, secure field, no Full Access), show a brief reason above the mic. / **剪贴板失败提示**：长按无法开始时（拒贴、空/过短/验证码类、密码框、无完全访问）在麦克风上方短暂显示原因。
 
 ### Removed
 - **Keep-alive settings & Live Activity**: remove Settings keep-alive mode picker and its note; delete the Dynamic Island Live Activity extension and all ActivityKit session code. Voice sessions stay on silent low-profile PiP only, with user-facing copy that never names Picture in Picture. / **保活设置与灵动岛**：移除设置中的保活方式选项及说明；删除灵动岛 Live Activity 扩展与全部 ActivityKit 会话代码。语音会话仅保留静默低感知 PiP，用户可见文案不再出现「画中画」。
+- **Clipboard 30s window & continuous rewrite**: drop the copy-time eligibility clock and multi-turn rewrite session; each long-press is an independent round. / **剪贴板 30 秒窗与连续改写**：去掉复制后资格计时与多轮改写会话；每次长按为独立一轮。
 
 ### Fixed
+- **Release notes cache**: load the remote What's New page with `reloadRevalidatingCacheData` so edited HTML is not stuck behind WebKit heuristic caching when the host sends no `Cache-Control`. / **更新说明缓存**：远程更新说明用 `reloadRevalidatingCacheData` 回源校验，避免服务器无 `Cache-Control` 时 WebKit 启发式缓存把旧 HTML 卡很久。
+- **Clipboard multi-intent commands**: "reply and translate to English" no longer collapses into a plain translation of the clipboard. The command contract now runs every spoken operation in order, translates the previous step's output instead of the material, pins the reply speaker (material "I" is the other party, reply "I" is the user), and rejects a restated material as a reply. / **剪贴板复合指令**：「回复并翻译成英文」不再塌缩成只把剪贴板译成英文。指令契约现按口述顺序执行全部操作，翻译作用于上一步产物而非材料，钉死回复视角（材料里的「我」是对方，回信里的「我」是用户），并禁止把材料复述后当作回复。
+- **Clipboard style-bias conflict**: dictation packs' "input is the user's draft, not a message from the other party" and "never answer the transcript" lines are stripped before the pack is injected as tone bias, so the personality can no longer override the reply intent. / **剪贴板风格偏置冲突**：注入语气底色前剔除听写风格包中「输入是用户草稿、不是对方消息」「不回答原文」等语句，避免人格设定压过回复意图。
+- **Clipboard prepare stuck**: after the first Allow Paste, do not double-`startRecording`; recover or cancel when host never confirms capture so UI cannot remain on「准备录音…」. / **剪贴板卡在准备录音**：首次「允许粘贴」后不再重复 `startRecording`；宿主未确认采音时及时恢复或取消，避免 UI 一直停在「准备录音…」。
+- **Clipboard prepare decision tests**: unit-cover restore/dedupe/adopt/abort matrices (including a 20-round stress case) so paste-alert reopen cannot regress into a second start. / **剪贴板准备态决策单测**：覆盖恢复/去重/领养/中止矩阵（含 20 轮加压），防止粘贴弹窗重开再次双发 start。
+- **Clipboard cold-start handoff**: when the host app is not alive, long-press stores a sticky voice+snapshot and opens `startflow` without entering fake「准备录音…」; after return (including default typing → forced voice), the user long-presses again to start blue clipboard recording. / **剪贴板冷启动交接**：宿主未活时长按只保留语音+快照粘性并走 `startflow`，不进入假「准备录音…」；返回后（含默认打字→强制语音）再长按才进入蓝色剪贴板录音。
+- **PiP arm re-jump**: keyboard open / Voice-tab appear no longer reopens `startflow` while a session is alive, warming, or within the arm cooldown; force-quit zombies can still arm after an 8s unreachable grace. / **PiP 反复跳转**：会话已存活/预热中或仍在拉起冷却窗内时不再重复 `startflow`；强杀后残留 session 在心跳失联超过 8s 仍可拉起一次。
+- **Clipboard prepare chrome**: while waiting for host capture confirm, the mic stays grey and disabled (not blue); blue + side captions appear only after confirmed recording. / **剪贴板准备态视觉**：等待宿主确认采音时麦克风保持灰色不可点（非蓝色）；确认录音后才显示蓝色与两侧文案。
+- **Cold capture first-press**: host retries a soft-dead / failed engine start once and rejects `running && !engineLive` as success. / **冷启动首次采音**：宿主对软死/失败引擎自动重建一次，且不把 `running 但无 live` 当作成功。
+- **Clipboard paste prompt spam**: idle affordance peeks `hasStrings` only; pasteboard *contents* are read only on long-press, so opening the keyboard no longer repeatedly requests paste permission. / **剪贴板粘贴授权刷屏**：空闲仅探测 `hasStrings`；正文只在长按时读取，打开键盘不再反复申请粘贴权限。
+- **Clipboard paste-alert continuity**: survive the system Allow Paste alert without snapping to the typing grid, keep blue clipboard chrome from prepare onward, and ignore the finger-up that follows long-press so stop stays tap-to-finish. / **剪贴板粘贴弹窗连续性**：系统「允许粘贴」弹窗期间不跳回打字键盘；准备阶段即显示蓝色剪贴板态；忽略长按后的抬手，仍需再点结束。
+- **Clipboard paste-alert voice sticky**: persist a short App Group prefer-voice + snapshot flag (with `synchronize`) across paste-alert dismiss/recreate so reopen stays on the voice keyboard with blue clipboard chrome instead of the default typing grid / red dictation mic. / **剪贴板粘贴弹窗语音粘性**：用 App Group 短时标记（并 `synchronize`）跨弹窗销毁/重建，重开仍进语音键盘并恢复蓝色剪贴板态，而不是默认打字键盘 / 红色听写麦。
 - **Custom polish style editor**: open create/edit with `sheet(item:)` so the form always loads the selected pack instead of a blank default template. / **自定义润色风格编辑**：新建/编辑改为 `sheet(item:)` 呈现，表单始终加载所选风格，而不再偶发显示空白默认模板。

+"""Replay complete production prompts against an explicit quality corpus.
+
+This is deliberately separate from XCTest:
+- XCTest protects deterministic prompt assembly and local fallbacks.
+- this script sends the *complete* system prompt and complete user payload to
+  the configured LLM, then records objective contract checks plus every output
+  for human quality review.
+
+It covers two protocols that must never be conflated:
+1. Dictation polish: the user message is the user's outbound draft. Questions
+   must stay questions and never be answered.
+2. Clipboard command: the user message contains material and an ASR command.
+   A reply command must produce a reply; a summary/review/translation must not.

+像用户本人说得更清楚，并让情绪更可读。不换人格、不升温、不降温、不改立场与亲疏。
+
+# Emoji 规则
+问句可加疑问向 emoji（🤔 / ❓），但必须仍是同一个问句。
+只映射原文已有情绪，不发明新态度；优先放在句末，最多 2 个。
+
+# 聊天节奏
+输出长度贴近原句（±20% 以内），不扩写成小作文。

+- 禁止以对方身份接话、附和、安慰或反问（「嗯」✘→「嗯，我在呢」）。
+- 极短确认/状态词近原样输出，禁止续写第二句，也不加 emoji。
