-# Linux ships in the same GitHub Release as the desktop, Android and HarmonyOS
-# assets.
-#
-# The entry point is dispatch-only (never a `push:` trigger), so nothing can
-# rebuild Linux packages from an arbitrary commit: `release-tauri.yml` dispatches
-# it automatically for a `v*-tauri` tag once the desktop assets are published,
-# and an administrator keeps the manual dispatch as the repair path. Packaging
-# runs the same Core/host/deb/rpm verification as CI and then attaches the
-# verified packages to that Release automatically - nothing is uploaded by hand.
-#
-# Because the tag now ships Linux unattended, the L01-L12 device acceptance in
-# docs/linux-egui-handoff/07-acceptance.md is a **pre-tag** gate: a tag must not
-# be cut for a Linux state that has not been accepted on real hardware.
+# Linux may accompany a desktop release only after independent device acceptance.
+# Both automatic dispatch and the reusable publication job require the repository
+# variable LINUX_ACCEPTED_RELEASE_TAG to match the immutable release tag exactly.
+# Build-only dispatches remain available without authorizing publication.

+# Awareness follow-up
+
+The desktop Awareness page groups cursor context, opt-in correction suggestions, and an initial opt-in expression-learning implementation. The initial implementation learns only a small set of global formatting directions, stores abstract evidence locally, and applies stable directions to future dictation prompts. It does not yet implement application-awareness controls, per-app/category profiles, a user blacklist, or the complete correction system requested by the user.
+
+## Reference and evidence
+
+A local Type4Me source checkout at upstream revision `f21339e214d65e9bd4d191ff5136513902e7473b` was reviewed. The installed app identifies itself as 3.2.0; equivalence to that checkout has not been established. The checkout is MIT-licensed: retain its copyright and license notice if source or substantial portions are ported. Relevant upstream files are `Sources/Type4Me/Services/IntelliSenseContext.swift`, `UserEditClassifier.swift`, `ExpressionProfileStore.swift`, `BatchCorrectionInference.swift`, and `Sources/Type4MeIntelliSenseCore/IntelliSensePrompt.swift` in https://github.com/joewongjc/type4me.
+
+The reviewed implementation separates app/control context, cursor context, correction detection, and expression learning. It classifies observed edits and rejects sensitive content and changes to facts or negation before treating edits as style evidence. Style profiles hold abstract features and use sample, day-span, consistency and decay thresholds before emitting limited form-only directives. Its batched correction candidates use independent sessions, multiple days and directional confidence. These are observations about that source revision, not claims about an inaccessible server or later app version.
+
+## Required implementation
+
+- Define independently controlled, opt-in learning and capture boundaries; keep secure fields, sensitive apps, uncertain target changes and blacklist entries excluded. Describe when contextual text may be sent to the configured model.
+- The initial implementation accepts only uniquely anchored formatting edits, rejects sensitive or content-changing observations, and stores bounded text-free global evidence. Opt-out stops observation and new-session application; users can clear the profile. Mixed edits and richer classification remain unsupported.
+- Extend the profile to app/category scopes with explicit precedence and decay, plus a user-maintained exclusion list. Validate reset and opt-out races across all hosts, and ensure form directives cannot override facts, explicit corrections or user instructions.
+- Correction suggestions now reject changes to numeric or negation signatures and sensitive contexts, while retaining explicit user confirmation. Add a richer lexical affinity model, conflicting-candidate handling and repeated-session evidence without treating one edit as a stable habit.
+- Integrate the controls into the single Awareness page and exercise opt-out, clearing, app exclusion, restart and prompt behavior across supported hosts. Add deterministic classification, persistence, safety, stale-observer and native integration tests before enabling the feature.

 - 重量级 job 用 `save-if: ${{ github.ref == 'refs/heads/beta' && (github.event_name == 'push' || github.event_name == 'workflow_dispatch') }}`：PR 只从基线分支恢复，不再各自复制一份 1.6 GB 依赖树（此前两个 PR 就占了 10.87 GB，把基线缓存挤掉）。
 - **禁止 `uses: actions/cache@v4`**：它会在每次运行时自动保存，包括 `refs/pull/<n>/merge` 这种此后再也不会被恢复的作用域。鸿蒙工具链（1.77 GB）和 Rime NDK（0.40 GB）都这样泄漏过——两个 PR 推送就能把 beta 的依赖树挤掉。规则统一成 `actions/cache/restore@v4` 无条件恢复 + 独立的 `actions/cache/save@v4` 且 `if:` 限定 beta。
-- `playwright` 与 `mobile-rime` 使用 restore/save 拆分；`swatinem/rust-cache` 用 `save-if` 达到同样效果。
-- `build-linux-egui` 保留 PR 内自写并开 `cache-on-failure: true`：失败的运行也会把依赖缓存存下来，下一次迭代仍然热；同时关掉 dev/test debug info，缓存更小、链接更快。
+- `playwright` 与 `mobile-rime` 使用 restore/save 拆分；`swatinem/rust-cache` 用 `save-if` 达到同样效果。Playwright 按引擎与版本分键，每个 runner 只下载、恢复自己的浏览器；新键首次使用需要冷下载。
+- npm 复合 action 内允许 beta 门控的 `actions/cache@v4`，其他 ref 只用 `cache/restore`；周期构建也可以维护 beta 下载缓存。
+- 历史标签修复入口是兼容例外：标签可能早于 npm 复合 action，继续使用原有 `setup-node` npm 缓存；常规 tag 发布使用只读复合 action。
+- Linux 测试与打包各自使用独立缓存，PR 只读、beta 写入；dev/test 关闭 debug info。Windows MSRV 新增独立缓存族，实际体积需在 beta 首次写入后由维护作业重新核算，不能把上表历史余量视为保证。
 - key 结构为 `v0-rust-<job>-<os>-<环境哈希>-<lockfile哈希>`：环境哈希含工具链与 `CARGO_PROFILE_*`，所以 stable / MSRV / release 天然分开，不要用跨平台 `shared-key` 混合。
+- 相同 `shared-key` 只是必要条件：恢复仍要求工具链/环境哈希和缓存路径版本兼容。CI 的 dev/test 缓存不能保证让 release 热启动，发布配置依赖 beta 的周期构建预热；不能把共同前缀当作已命中的证据。
 - 原生胶囊（`native-capsule` job）原本是一个 `pull_request`-only workflow：缓存写在 `refs/pull/<n>/merge`，这个作用域此后再不会被恢复，而 beta 上没有 job 产出同 key 的树，所以 PR 永远冷编译。现在它在 `ci.yml` 里，用 `shared-key: native-capsule` + beta 门控的 `save-if`，并且由 `capsule` 区域门控——常见 PR 完全不会为它拉起 runner。
   曾试过把它并进 `cross-platform`（省两台 VM），实测否决：run 40510306688 里那三个命令在 Windows 关键路径上花了 43+53+21 s，比它省下的两台 runner 更贵。要合并先要确认那套 `ui,host` feature 在桌面 job 的缓存里是热的。
 - `Cargo.lock` 变化时精确键失效，但 `restore-keys` 前缀回退会拿到同前缀的旧缓存，所以“锁变了”不等于“全冷”——前提是那份没被淘汰，这正是要守预算的原因。

+## 8. 2026-11-08 检查与优化依据
+
+基线：`c002b56c38d81bcd5044ddb22597a4e78ff2a88d`。以下是历史运行证据，不是本次修改后的远端性能结果：
+
+| 证据 | 观察 | 对应调整 |
+|---|---|---|
+| [CI 42485909147](https://github.com/Open-Less/openless/actions/runs/42485909147) | 浏览器串行执行 923 秒；整轮约 16.9 分钟 | Chromium / WebKit 两个 runner、各 1 worker，保留原 `UI motion (Chromium + WebKit)` 汇总检查 |
+| [CI 42402206738](https://github.com/Open-Less/openless/actions/runs/42402206738) | Windows 1518 秒，其中 MSRV 两步 274 + 151 秒 | MSRV 并行独立缓存；stable 与 MSRV 均为必需结果 |
+| [CI 42445115251](https://github.com/Open-Less/openless/actions/runs/42445115251) | Windows MSRV 两步 225 + 122 秒；浏览器分拆在该分支已有运行证据 | 不扩大平台/架构集合，仅拆开现有串行工作；保留两浏览器的失败证据 |
+| [桌面构建 42073710377](https://github.com/Open-Less/openless/actions/runs/42073710377) | Intel macOS 构建 2078 秒、Windows 1092 秒 | 不降低 release 优化级别；Windows NSIS 编译后，MSI 使用 `tauri bundle`，复用同一二进制 |
+| [macOS 构建 42263206938](https://github.com/Open-Less/openless/actions/runs/42263206938) | Rust 日志 `No cache found.`，编译约 14m52s | 限制一次性 tag 缓存写入，保留 beta 的周期预热 |
+
+超时证据：本次查询 `actions/runs?status=timed_out&per_page=10` 返回 0 条，不能据此认定历史故障都是超时。现有 Android APK 三个 job 未设上限，现补为计划 10 分钟、构建 90 分钟、发布 30 分钟；APK 构建步骤 70 分钟。浏览器单引擎步骤 20 分钟、job 40 分钟；下载、编译和测试等主要阶段各设步骤上限。这些是包含冷启动余量的防挂起边界，不是性能目标。前端脚本每文件最多 120 秒，打印文件名、耗时，超时返回 124；TypeScript 使用 `node --import tsx` 直接执行，减少启动进程，并避免超时只杀掉 tsx CLI 而留下测试子进程。Cargo `--timings` 与 Actions 步骤日志用于后续调整；进程被强杀时不保证生成完整 Cargo HTML。
+
+npm 下载缓存使用锁文件精确键，缺失时按 OS/架构前缀恢复已有 tarball；仍执行 `npm ci` 校验锁文件和完整性。CI 优先使用本地下载缓存，并限制请求超时/重试。`node_modules` 不缓存。本仓库使用 npm 锁文件，没有新增 pnpm 流程。TypeScript 增量信息写入忽略的 `node_modules/.cache/tsc`，每次 Vite 仍重新打包。
+
+本地复测：Linux、Node 24.22.1（远端 CI 仍使用 Node 22），三次均按 `npm run prebuild` → `tsc` → `vite build` 执行。关闭增量时 26.64 秒；删除增量信息后首次构建 27.75 秒；重复构建 13.96 秒，比非增量约少 48%。三次输出的全部 73 个文件 SHA-256 一致。收益针对重复构建，首次构建没有提速；该样本不代表 macOS/Windows 原生构建或 GitHub 整轮 CI 的加速比。
+
+浏览器失败日志与 Cargo timings 保留 7 天；安装包和发布中转 Actions artifacts 保留 14 天。GitHub Release 已发布附件不受此期限影响。Android 相同 ref/ABI/profile/signing 的手动运行取消旧任务，tag 发布不被新运行中途取消。既有 PR 门控、完整平台集合与文档变更策略不变。
+
+矩阵取舍：浏览器由一个串行 job 拆成两路，Windows MSRV 由 stable job 拆出，再增加两条轻量汇总检查以保留原必需检查名。单次全量 CI 的 runner 数会增加，目标是缩短关键路径；没有增加浏览器、平台或架构组合。实际墙钟收益仍受 GitHub runner 排队、冷缓存与新增缓存体积影响，需要合并后的同类运行对照，不能把各步骤节省相加作为整轮加速比。
+
+本地验证：`npm test` 完成构建和全部 166 个测试文件；修改的工作流通过 actionlint；两种浏览器分别 `playwright test --list --project=…`，各发现 116 个测试。新增行为用例覆盖必需检查的失败/取消/跳过、挂起的 JS/TS 子进程、NSIS 失败中止和 MSI 二次打包。Windows 安装器实际打包、macOS 签名仍需远端验证；多平台首轮 CI 结果见下一节。
+
+## 9. 第二轮：减少 Windows 重复编译
+
+[首轮 CI 42490834011](https://github.com/Open-Less/openless/actions/runs/42490834011) 全部通过，执行窗口（首个 job 开始到最后一个 job 结束）为 14 分 28 秒。父提交的完整 CI 为 21 分 14 秒，缩短 31.9%；这不包含前者 3 秒、后者 24 分 03 秒的首次调度等待。首轮各 runner 时长合计为 94 分 20 秒，较基线 82 分 40 秒增加 14.1%，因此继续优化重复工作。
+
+Windows stable 首轮为 13 分 36 秒，其中默认 host 测试编译 287 秒，随后诊断 feature 的 `cargo check` 又花 194 秒。日志显示前者使用 `test` profile（无 debug info），后者切到 `dev` profile（有 debug info）并重新检查整张依赖图。诊断检查改为 `cargo build --profile test --lib --bins`，使用前一步的依赖产物，同时实际编译、链接 feature-on 的生产 lib/bin；`cfg(not(test))` 仍生效，独立诊断运行测试也保留。
+
+独立 backend 测试此前使用自己的 target，首轮另花 101 秒。它与 Tauri 锁文件的 394 个条目中有 393 个相同；现在 Windows stable 的这一步使用 `--target-dir src-tauri/target`，让 Cargo 复用版本、features、profile 均匹配的依赖，其余仍独立编译。缓存也恢复为原有单一 target 路径，避免为同一依赖图存两份目录；MSRV 仍保留独立工具链缓存。
+
+`ci-performance.test.mjs` 用两个离线 Cargo 测试包执行实际工作流命令，确认共享依赖在两步中均为 `fresh`，诊断命令产出非测试二进制，并用故意损坏的 feature-on 生产代码确认它会失败。第二轮不增加 runner、不减少现有测试；实际节省需等待新的远端运行，不能直接将 194 秒和 101 秒全计作收益。

+## 文字插入与实时原文
+
+macOS 保留录音结束后的自动文字插入，以及胶囊中的实时原文显示；不再提供“实时原文显示在输入框”的实验选项。输入框实时写入曾出现在内部预览构建中，并未包含在已发布的 Beta.4 中。本轮撤下该预览实验，历史预览保存的开启状态也不会启动它，避免普通听写或已完成的流式输出被错误转入复制兜底。胶囊原文显示与向目标输入框写入是两个独立功能。
+
+Windows 的“实时原文显示在输入框”位于：设置 → 高级功能 → 文字插入。该选项继续使用 Windows TSF 插入管线，选项名称不附带操作系统后缀。
+
+macOS 自动插入仍依赖有效输入目标、辅助功能授权和编辑器能力。目标定位直接查询已捕获的前台应用，并在写入前复核焦点所属应用，避免系统级 AX 焦点查询失败或焦点变化造成错误写入。不能确认安全目标或插入失败时保留可复制结果。原生测试夹具与用户在预览版中的验证不代表所有第三方编辑器均已验收。
+
+macOS 辅助功能设置提供带应用图标的浮动引导，帮助用户将应用拖到系统授权列表并启用权限；其他系统不显示这项 macOS 专属引导。
+
+## 更新选择
+
+桌面检查同时请求阿里云滚动清单与 GitHub Release 元数据。GitHub 可达时以该渠道的已发布 GitHub 版本为准，Beta 与 Stable 分开；GitHub 匿名 API 被限流或失败时，在同一总超时预算内尝试官方公开发布 feed 和资源页；两条 GitHub 路径均不可用、超时或请求失败时使用阿里云结果。
+
+同版本并发读取两条安装包链路的最多 64 KiB，用首字节延迟与传输速率比较。阿里云延迟不超过 GitHub 的 120%，且速率不低于其 80% 时视为接近，优先阿里云；GitHub 明显更快或探测无法确认阿里云优势时使用 GitHub。判断使用实际网络测量，不读取用户位置。探测上限 4 秒，不预下载整包。
+
+GitHub 版本从安装包签名的 trusted comment 读取并核对所属 tag，保留 build metadata。版本元数据仍须由 Tauri 的安装包签名校验确认；没有签名版本或版本不匹配不能静默接受。此更新不改变 Android 独立更新路径。
+
+## 设置与资源生命周期
+
+高级功能是一级分类。本地语音模型、语音增强与播放抑制、感知、启动诊断、自建同步服务器与调试工具通过独立子页进入；Windows 另有文字插入子页。感知统一容纳光标上下文与短句行为、手改学词，以及受支持桌面平台上的实验性表达格式学习，各卡片之间留出明确间距。手改学词不再占用单独的同级菜单。模型、语音增强、感知及文字插入等实验功能显示 Beta 标记；表达学习的范围和未完成项见 [感知后续工作](awareness-follow-up.md)。
+
+退出页面即卸载控件与订阅，不为已访问的实验页面保留隐藏树。设置入场完成后暂停被遮住的主界面绘制，退场开始前恢复，保持开关动画中的底层画面连续。
+
+界面曲面默认使用 16 px 的连续圆角；录音胶囊、实时转写胶囊及开关维持原有的胶囊形几何，纠正规则添加按钮使用 8 px。选择弹层与分段控件保留未裁切的轮廓与焦点反馈。容器用微明度色阶区分层次；暗色文本字重由 token 调整，数字统一 tabular-nums。流式新增字符保留逐字 blur，吸附位移和宽度弹簧使用过阻尼，并遵守减少动态效果。点赞按钮沿用一次性短回弹，与吸附动效分开。
+
+WebGL 能力探测在完成后主动释放临时上下文；着色器、程序和缓冲区初始化失败也走资源释放路径。聊天头像只在进入可视区域时订阅共享动画，隐藏窗口暂停 RAF，最后一个订阅者退出后释放 GL 与画布。流式字符动画结束即撤掉 blur，不给全部字符长期设置 will-change。已移除的 Less Computer 与 Claude 控制台不再注册桌面 IPC、相关热键及后台轮询线程。
+
+胶囊的原生点击区域使用 AppKit 的窗口本地坐标，主胶囊与每个镜像分别保存区域。区域刷新不因连续动画而反复推迟；鼠标按压期间保持既有点击归属，直到松开，避免展开语言菜单时的窗口扩容丢失鼠标事件。透明区域与原文条继续穿透；菜单的滚动区域与真实控件拥有输入，1 px 焦点代理不拥有鼠标区域。

+# Provider prompt cache contract
+
+The client optimizes reusable input prefixes. It does not cache model outputs or skip model calls. Cache availability, minimum lengths, expiry and routing remain properties of the selected service and model. A token-weighted hit rate is not a request success rate; unique input and cold requests remain in the denominator when reported.
+
+## Request boundaries
+
+Fixed style, translation and question-answering instructions precede changing application and cursor context. Existing context escaping, text envelopes, trailing injection defenses and output constraints remain intact. Custom style templates and vocabulary order are not rewritten. Ordinary dictation does not acquire unrelated conversation history to inflate the shared prefix.
+
+Provider-specific parameters are selected from the actual HTTPS origin, API path, request format and known model capabilities, rather than the channel's display name or template. Unknown gateways retain the shared prefix improvement without unverified vendor parameters. User-supplied routing headers and cache settings take precedence.
+
+Routing keys are bounded opaque hashes of service, model and reusable system prefix. They contain no credentials, raw prompt, generated application context or per-request UUID. Cache breakpoints divide an existing system string into contiguous slices: concatenating the slices must reproduce the original text exactly. Only the static slice receives a system cache marker. For growing Anthropic conversations, a second marker may cover the last completed assistant turn; the current user input is not marked. Multi-turn OpenAI requests retain implicit history caching alongside the static explicit breakpoint.
+
+## Service strategies
+
+| Service and format | Strategy |
+| --- | --- |
+| DeepSeek official APIs | Stable prefixes; provider-managed implicit caching. No OpenAI cache parameters are forwarded. |
+| OpenAI Chat Completions / Responses | Stable routing key for related prefixes. Known GPT-5.6 and GPT-6 Responses models additionally mark static developer input with an explicit breakpoint. Older models retain implicit caching. |
+| Anthropic Messages | Mark the stable system content with the default ephemeral cache policy for Claude models. |
+| OpenRouter Chat Completions / Messages | Stable `session_id` for cache-aware routing; explicit stable-system markers for supported Anthropic models. Existing route selection is preserved. |
+| Ark Chat / Responses | Stable prefixes for all models. Only documented Seed 2 series receive `X-Prompt-Cache-Id`; DeepSeek models do not receive this Seed-specific option. |
+| DashScope | Stable prefixes; explicit markers only for verified standard API/model combinations. Coding-plan and unsupported model endpoints retain implicit behavior. |
+| Native Gemini, Codex and other gateways | Shared stable prompt composition. No generic endpoint's cache flags are assumed compatible with their transport. |
+
+The policy does not create separate remote cache objects, extend retention, enable response storage, send paid warm-up requests or change provider/model selection. An explicit marker can incur a provider's normal cache-write charge; its benefit depends on reuse before expiry.
+
+## Accounting and validation
+
+Usage records retain the service and protocol snapshot and the raw returned quantities. Canonical Chat Completions, Responses and Gemini input totals include cached input; Messages input is additive with cache reads and writes. Ambiguous or missing fields retain unknown semantics. Old records are not retroactively assigned the current service or a guessed denominator.
+
+The displayed rate is `sum(cache reads) / sum(comparable total input)` for the same reported records. The UI exposes the number of comparable reports and groups by service, channel, model and protocol. This remains a partial ledger: native Gemini/Codex recording, every request attempt and unreported usage require separate work. Neither a missing report nor a short uncached request proves a client failure.
+
+Acceptance checks cover origin/model/format boundaries, exact text preservation, stable keys across application changes, caller overrides, inclusive/additive usage, unknown values, overflow and streaming report merging. Service-side improvement must be measured from subsequent real responses; local request tests cannot establish a universal 97–98% cache rate.

+- 高级功能采用独立子页；感知页面的卡片保持清晰间隔，离开页面时释放控件与订阅。
+- 历史列表和用量记录使用容器内滚动；改善输入法选字时的回车处理、消息跟随和跳至最新。
+
+## 输入与胶囊
+
+- 修复内部预览中 macOS 终稿插入错误进入手动复制兜底的回归，避免流式内容已写入后再次弹出复制窗口。
+- 保留胶囊内实时原文显示。macOS 输入框内实时原文实验已从内部预览撤下；该实验未包含在公开 Beta.4 中。
+- Windows 输入框内实时原文设置集中到「高级功能 → 文字插入」。

+# Service usage accounting follow-up
+
+The initial desktop page reads retained dictation history, which is capped and can be cleared. It is not a service usage ledger. Provider labels in those records do not represent retries or complete billing data.
+
+An initial bounded, text-free local ledger and background writer now record explicitly reported tokens from desktop OpenAI-compatible text-polisher responses. The desktop page presents those reports separately from history-derived counts and labels them incomplete. Gemini, Codex, SIWC, multimodal, ASR, TTS, retries and all other call paths are not yet fully covered. The writer's error count is process-local; durable loss reporting and an explicit shutdown drain remain required. No historical token values can be recovered from the existing history.
+
+Known official Chat Completions services request streaming usage when their endpoint/model supports it and an observer is attached. An interrupted stream may not return its final usage report. Unknown gateways receive no unverified usage option. See the [provider cache contract](prompt-cache-policy.md) and its official references.
+
+New reports retain a service/protocol snapshot and explicit inclusive or additive cache accounting derived from canonical response fields. The cache dashboard groups comparable reports by service, channel, model and protocol; it shows the count of comparable saved reports, not coverage of all actual attempts. Legacy and ambiguous reports keep unknown cache semantics. Existing raw quantities are preserved, and no current endpoint or model configuration is assigned retroactively.
+
+To satisfy complete usage accounting, add a separately persisted, bounded, local ledger at the service-call boundary. Record a unique attempt identifier, timestamp, operation (including dictation post-processing, translation, selection, QA and other call sites), provider and model, outcome, and provider-reported quantities. Preserve unknown quantities as unknown, not zero; never infer token counts or price from characters. Capture ASR audio units and TTS units where the underlying provider reports them. Cover streaming, non-streaming, retries, cancellation, errors, multimodal calls and supported provider protocols, with tests proving one record per actual attempt and no secret or text content in the ledger. Distinguish missing legacy data from a zero-usage interval. Do not silently attach current model prices to historical requests.
+
+Expose aggregated date ranges and paginated, filterable records through the existing host contract, independent of history deletion. Add migration, retention and explicit deletion controls, deterministic aggregation tests, and UI tests for partial data, empty states and failed reads. The current history-derived view must be replaced or clearly separated when the ledger exists.

-//! Where the in-app updater looks for release manifests.
-//!
-//! # Background
-//!
-//! The updater used to read its manifest from the GitHub Release assets
-//! (`releases/latest/download/latest-{target}-{arch}.json`, and a `-beta` twin per tag). That
-//! forced every release to carry fourteen `latest-*.json` files — seven target/arch entries
-//! times a `-mirror` twin — all repeating the same three fields (`version`, `url`, `signature`),
-//! and every new release re-uploaded the same file names because the Stable endpoint was a
-//! rolling pointer.
-//!
-//! The manifests now live on the project's own CDN:
-//!
-//! ```text
-//! https://dl.aeoform.com/updates/stable/latest-{target}-{arch}.json
-//! https://dl.aeoform.com/updates/beta/latest-{target}-{arch}-beta.json
-//! ```
-//!
-//! Two properties matter:
-//!
-//! - **One rolling file per platform.** The CDN name is stable per channel, so a release never
-//!   accumulates manifest copies; publishing overwrites in place.
-//! - **Channel separation is a path, not a filename suffix.** `/updates/stable/` and
-//!   `/updates/beta/` are distinct locations, so a Stable client cannot walk into a Beta
-//!   manifest by accident.
-//!
-//! The manifest body is unchanged (`version`, `pub_date`, `url`, `signature`), so
-//! `tauri-plugin-updater` keeps owning download, minisign verification and platform install.
-//! Artifact URLs inside the manifest point at the same CDN (`/releases/{tag}/{asset}`), which
-//! is what mainland-China users download from.
+//! Concurrent release discovery and bounded transport sampling for the updater.
+//! GitHub owns release freshness; the rolling CDN is an independent backup and accelerator.
+//! Tauri still verifies the signed artifact and version before installation.
