 ### Fixed
+- **Signed-out AI billing safety**: switch every AI path back to user-owned BYOK when the account signs out or expires, and reject cached managed grants unless the host has confirmed an authenticated session. / **未登录 AI 计费安全**：账号退出或过期时将所有 AI 路径切回用户自备 BYOK，并在主 App 未确认有效登录会话时拒绝使用缓存的托管 Grant。
+- **Suspension-safe analytics**: batch uploads in the foreground or a system-granted refresh task, close SQLite outside authorized execution windows, release cancelled leases immediately, and keep keyboard extensions recording-only to prevent system termination from database locks. / **安全挂起埋点**：仅在前台或系统授权的刷新任务中批量上传，在授权执行窗口之外关闭 SQLite，并立即释放已取消的租约，同时让键盘扩展仅负责记录，避免数据库锁触发系统终止。

 - **Cross-process settings safety**: App Group updates now write only changed fields so a stale main-app or keyboard-extension snapshot cannot overwrite newer unrelated settings. / **跨进程设置安全**：App Group 更新现在只写入发生变化的字段，避免主 App 或键盘扩展的旧快照覆盖其他较新的设置。
 - **Account-data freshness**: Settings and Account now share one background-refreshed snapshot, preserve cached content on failure, retry transient read errors, and isolate optional referral outages from core account and credit updates. / **账号数据新鲜度**：设置页与账号页现在共用同一份后台刷新快照，刷新失败时保留缓存内容，对瞬时读取错误自动重试，并避免可选邀请接口故障影响账号与积分更新。
+- **Account purchase recovery**: keep App Store credit packs independent from account-snapshot failures, retry transient product loading, cancel stale account tasks safely, and return expired sessions to sign-in without requiring a manual sign-out. / **账号内购恢复**：积分包不再受账号快照失败影响，商品瞬时加载失败会自动重试，旧账号任务可安全取消，登录过期后会直接返回登录状态，无需手动退出。
 - **Managed AI task routing**: credit-backed requests now preserve dictation, translation, editing, question, clipboard, custom-skill, and agent intent so the gateway can disable costly reasoning for low-latency transforms. / **托管 AI 任务路由**：积分请求现在会保留听写、翻译、编辑、问答、剪贴板、自定义技能与 Agent 意图，让网关可为低延迟转换任务关闭高成本思考。

+# Clipboard semantic models
+
+This directory contains the reproducible training inputs and evaluation output
+for OSGKeyboard's fully local clipboard analyzer.
+
+## Scope
+
+The model suite predicts five independent intents (`task`, `question`,
+`invitation`, `complaint`, and `replyableMessage`) plus three-way sentiment.
+`replyableMessage` distinguishes messages that invite a response from terminal
+acknowledgments, personal notes, quoted questions, and factual notices. Apple
+data detectors remain responsible for dates, addresses, phone numbers, and
+URLs; `NLTagger` provides best-effort person and organization names.
+
+The corpus contains 7,272 Chinese and English records:
+
+- 4,660 generated training records
+- 1,260 generated validation records
+- 1,260 template-held-out test records
+- 92 manually authored golden records
+
+No user clipboard content is included.
+
+## Reproduce
+
+```bash
+python3 Scripts/clipboard_semantics/generate_corpus.py
+xcrun swift Scripts/clipboard_semantics/train_models.swift
+```
+
+The trainer balances labels, trains maxEnt and BERT candidates, calibrates
+high-precision thresholds, writes detailed errors to `evaluation-report.json`,
+and copies the selected models into
+`OSGKeyboardShared/Resources/ClipboardSemantics`.
+
+## Deployment decision
+
+Only maxEnt models are eligible for keyboard automatic routing. Create ML BERT
+transfer models depend on `NLContextualEmbedding` assets that are not guaranteed
+to exist in a simulator or keyboard-extension runtime, so they remain evaluation
+candidates only.
+
+The selected intent models passed the automatic-routing precision gates. The
+replyable-message model reached 100% test precision and 97.96% golden precision;
+its measured recall remains part of release monitoring. The complaint model is
+also high precision but remains conservative because golden recall is limited.
+Sentiment returns `unknown` unless confidence and top-two margin checks both
+pass.
+
+Synthetic results are not treated as production truth. Real opt-in, anonymized
+or manually reviewed examples are still required before widening labels or
+lowering thresholds.

-  <p>OSGKeyboard provides an iOS custom keyboard and a macOS menu-bar dictation app. iOS uses Apple's on-device speech APIs by default; macOS can use a downloaded local Qwen3-ASR model.

+  <p>OSGKeyboard provides an iOS custom keyboard and a macOS menu-bar dictation app. iOS uses Apple's on-device speech APIs by default; macOS can use a downloaded local Qwen3-ASR model. The core local and user-configured-provider features do not require an OSGKeyboard account. On iOS, first-run onboarding includes a limited anonymous AI trial, and you may later sign in with Apple and choose managed credits instead of supplying provider credentials. This policy explains these options.</p>
 
   <h2>What we collect</h2>
   <ul>
     <li><strong>Voice audio</strong> — captured only while you actively record. On a local engine, audio is transcribed on-device and raw audio is not uploaded. With a user-configured cloud engine, recordings are sent directly to that ASR provider. If you explicitly choose managed credits, recordings are sent through the OSGKeyboard managed gateway at <code>account.osglab.com</code> to the managed ASR provider for transcription. OSGKeyboard does not keep raw recordings after the request is processed.</li>
     <li><strong>Transcribed text and cursor context</strong> — after ASR, the transcript (not audio) may be sent for polish when you use a configured LLM or managed credits. A small amount of text around the cursor may be included to continue naturally. Secure fields are never captured, and cursor context is not written to logs or voice history. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>.</li>
+    <li><strong>Speaking-style learning</strong> — only after you tap “Generate My Style,” eligible pairs of pre-polish and final text, together with the polish-style prompts that produced those examples, are sent to your configured AI service. Native speech and explicit user edits are used to infer recurring habits; historical prompts are supplied only to distinguish and remove AI-added style. The generated prompt is shown for review and is not saved or activated until you confirm it. When you later invoke a conversational clipboard-reply skill while a reviewed user-created style is active, that style prompt is sent with the copied text so the reply can follow your wording and rhythm; built-in polish personalities are not attached. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>.</li>
     <li><strong>AI mode questions</strong> — in AI keyboard mode, your spoken question text—or a question you tap from an idle suggestion—is sent to the selected AI service to generate an answer. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>. When the selected service supports server-side web search, it may retrieve public web results for time-sensitive answers.</li>
+    <li><strong>Anonymous onboarding AI trial</strong> — before you sign in, onboarding can issue a short-lived, feature-limited credential after Apple App Attest verifies a genuine app installation. The four fixed lessons may send one voice transcript, an explicitly copied lesson sample for translation and reply, and one transcribed AI question through <code>account.osglab.com</code>. This flow does not create an account, process an Apple identity token, use credits, or upload raw voice audio. The copied lesson sample is temporary and does not enable or populate clipboard history. The service keeps only pseudonymous integrity, request-state, feature, and metering records needed to enforce the one-use limits and investigate abuse; it does not retain request or response bodies.</li>
     <li><strong>AI suggestions and OSGKeyboard web pages</strong> — the main app may request public suggestion titles from <code>key.osglab.com</code>; no voice, transcript, clipboard body, API key, or ordinary keystroke content is included. Opening the update page requests public content from <code>download.osglab.com</code>. Those hosts may process ordinary connection metadata such as IP address and request time.</li>
     <li><strong>AI Agent skills, Shortcuts, and maps</strong> — when you deliberately run a skill, the selected or copied text and skill prompt are sent to your configured LLM provider. Reminders, Calendar, and Notes exports pass the generated result on-device to an Apple Shortcut you install. Navigation opens an address or route in Apple Maps, Amap, or Baidu Maps; the selected provider's policy applies.</li>
     <li><strong>API credentials</strong> — stored in the iOS Keychain and shared between the main app and keyboard extension. When iCloud settings sync is enabled, keys replicate through iCloud Keychain (not iCloud KVS JSON).</li>
     <li><strong>Optional OSGKeyboard account and purchases</strong> — no account is required for local transcription or user-configured providers. If you choose Sign in with Apple, the account service processes the Apple identity token, a pseudonymous OSGKeyboard account identifier, optional display name, device-integrity evidence, credit balance, referral state, and StoreKit transaction identifiers needed to verify consumable credit purchases. Account session tokens stay in the main app's private Keychain; the keyboard extension receives only a short-lived, scope-limited managed-service grant. You can sign out or delete the account in the app.</li>
     <li><strong>App preferences</strong> — engine mode, language, and keyboard settings stored in App Group UserDefaults. Optional iCloud sync mirrors eligible preferences, usage statistics, and voice history through your private iCloud account. Clipboard-history consent and its suggestion-strip switch stay device-local and are not activated by iCloud settings sync.</li>
-    <li><strong>Optional first-party product analytics</strong> — enabled by default and removable at any time in Settings. OSGKeyboard sends only fixed event names and fixed categories about app/keyboard sessions, AI feature outcomes and duration ranges, purchase-page interactions, and invitation actions, together with an app-scoped random installation identifier and safe app/OS version labels. It never includes keyboard input, audio, transcripts, cursor context, prompts, model output, contacts, file or device names, Apple identifiers, email, credentials, advertising identifiers, or free-form properties. Turning analytics off deletes queued events; turning it back on creates a new installation identifier.</li>
+    <li><strong>Optional first-party product analytics</strong> — enabled by default and removable at any time in Settings. OSGKeyboard sends only fixed event names and fixed categories about app/keyboard sessions, AI feature outcomes and duration ranges, purchase-page interactions, and invitation actions, plus daily aggregate counts of manually committed Chinese, Latin-letter, and other graphemes and four aggregate input-session classes. These records include an app-scoped random installation identifier and safe app/OS version labels. They never include typed text, pinyin, candidates, individual key events or timing, audio, transcripts, cursor context, prompts, model output, host-app or field information, contacts, file or device names, Apple identifiers, email, credentials, advertising identifiers, or free-form properties. Turning analytics off deletes queued records; turning it back on creates a new installation identifier.</li>
     <li><strong>Optional clipboard history</strong> — off by default. When you turn it on, the keyboard may read text from the clipboard on this device or from Universal Clipboard; iOS does not provide a reliable way to distinguish those sources. Up to 15 accepted text items are stored only in the local App Group shared by this device’s host app and keyboard extension. Turning history off stops capture, turns off the suggestion strip, and keeps existing items. Reset Settings also keeps them; only the separate confirmed “Clear clipboard history” action removes them. There is no fixed expiry. Secure fields immediately hide clipboard UI and are not captured. Conservative filters reject common OTP shapes, private-key headers, JWTs, Bearer tokens, recognizable provider-key prefixes, and common Luhn-valid 16-digit card numbers, but cannot identify every password or secret. A rejected item can still be pasted through iOS; it is simply not added to history. Clipboard history is not automatically sent to AI. If you insert an item and then actively use polish, the inserted text may be included as context sent to the provider you configured.</li>
     <li><strong>Personal dictionary and typing learning</strong> — personal terms may sync through your private iCloud account when enabled. Chinese candidate frequencies and English suggestion choices remain in the local App Group and can be cleared separately without deleting the personal dictionary. OSGKeyboard does not upload this learning data.</li>
     <li><strong>macOS local speech models</strong> — when selected, Qwen3-ASR model files are downloaded from Hugging Face and remain in the Mac app's local application-support directory until you remove them. Local inference does not send your audio to Hugging Face or OSGKeyboard.</li>

+  <p><strong>Voice history and learned styles</strong> — successful transcripts may be saved in the main app’s History tab (up to 300 entries). Each row can retain the displayed final text and, when available, the corrected ASR text from before AI polishing plus a deduplicated snapshot of the polish-style prompt used for that take; the pre-polish text is not shown in History. Raw audio and cursor context are not stored with the row. Clearing all history also removes retained prompt snapshots. A generated style is stored only after you review and save it. With iCloud settings sync enabled, eligible history and custom styles may sync across your devices through your private iCloud account.</p>
   <p><strong>Clipboard history</strong> — stays in this device’s App Group, is capped at 15 entries, does not sync through iCloud, and has no fixed expiry. Turning the feature off or resetting settings keeps existing items. Use the separately confirmed clear action to delete them.</p>

+  <p><strong>Product analytics</strong> — queued events expire locally after 34 days.

Account deletion and analytics opt-out delete local analytics records. Analytics identifiers are not used for cross-app tracking or advertising.</p>
   <p><strong>Typing learning and Mac models</strong> — Chinese and English learning data stays local and can be cleared from typing settings. Downloaded Mac speech models remain until you remove the model or delete its local files.</p>
   <p><strong>Optional account</strong> — account profile, credit ledger, StoreKit audit records, and limited anti-abuse records are retained by the account service while the account is active. Account deletion removes the active profile and credentials; pseudonymous ledger, purchase-audit, and time-limited anti-abuse records may remain where required to prevent replay, fraud, or abuse.</p>
