DSH 1.0.22 发布配套 + 仓库工程整理 - #33
Conversation
- 候选视频改为 opacity:1，封面图置顶遮盖，避免 Chromium 推迟解码几乎透明的视频导致 readyState 停留 0 - Range 诊断探针与真实媒体请求并行，不再挤占冷启动的 8 秒预算 - 冷启动首帧判定改用 waitForPresentedFrame（呈现一帧即可），三帧稳定仅用于已挂载槽位复用 - 同 URL 视频重复导入复用解码器并原地 seek，不再因海报 token 变化强制冷启动 - 媒体服务器信任来源补充 127.0.0.1/localhost/[::1] 回环域名 - 版本升至 1.0.20 以便安装器向 1.0.19 用户下发更新
- 本地零复制视频在 staging 阶段预热读文件头 2MB + 尾 4MB（moov 区）， 把 Defender 首次扫描与冷缓存成本移出渲染验证死线 - 渲染器上报首帧/Range 探针超时类失败时，事务层用原 payload 自动重试 一次并重新验证；解码类失败与图片不受影响 - 不改动任何验证死线常量（客户端 8s / host 10s 保持不变） - 版本升至 1.0.21
- 页面初始化时静音播放 1.5KB 内置黑屏 MP4（faststart），提前初始化 Chromium 解码/GPU 媒体管线，消除新机首次导入的浏览器侧冷成本； 播放结束或 15 秒后自动移除，全程 best-effort 不影响页面 - 视频元素记录媒体事件时间线（loadstart/progress/stalled/error 等 带 performance.now 时间戳），超时/失败错误信息追加该时间线—— 无事件即请求未启动，loadstart 后停滞即首次 Range 读被扫描拖住 - Live verify 失败错误追加事务阶段耗时（stageMedia/rendererVerify 等）， 现场报告无需本地日志即可定位慢在哪一步 - 并入未发布的 1.0.21
- 视频应用拆为两阶段：阶段一只硬性校验 Range 探针、封面加载与 play() 发起，通过即提交封面并回执 ok(videoReady=false)，verify 立即通过 - 阶段二在 60 秒窗口内等首帧，呈现后原地 seek 并翻 data-bc-video-ready， 封面淡出、视频淡入；解码器报错或超时仅保留封面并降级上报，永不回滚 - startCandidatePlayback 只要求播放已发起：play() 1.5 秒未兑现视为解码器 预热中，不再判死；waitForVideo 识别等待开始前已发生的解码错误 - 慢机器在架构上不再可能使事务失败，新机首帧超时从根上消除 - 状态新增 videoReadyClients/videoPendingClients/lastVideoError 透出预热 进度与降级诊断；回执协议向后兼容老客户端 - 新增冻结冷启动（零媒体事件）与预热状态测试；升版 1.0.22
- DSH 客户端 (client.js) 大幅扩展，补充插件测试 - adapter-dsh 桥接/session 与 core 事务/媒体校验更新 - 新增 publish-github-package.yml CI - README 文案精简，补画窗参考与安装说明 - installer 脚本与集成文档/测试修补
- .gitignore 分组重排，新增 .mimosa/ .workbuddy/ .cache/ .tmp/ 等本地草稿目录 - 新增 scripts/README.md，按 npm 插件/Windows 安装包/运行测试 三类索引脚本 - 删除未跟踪的本地工具目录 .mimosa/ .workbuddy/

41-51: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win可重试判定依赖渲染端的中文文案。
RETRYABLE_RENDER_VERIFY_PATTERN匹配verify.reason中的「首帧」与「Range 探针」。该文案由渲染端（DSH client）生成，不是稳定契约。渲染端改写提示语或增加英文/本地化输出后，冷启动重试会静默失效，视频首帧超时的问题会重新出现，且没有测试能提前发现。建议让 verify 结果附带结构化原因码（例如
reason之外增加code: "first-frame-timeout" | "range-probe-failed"），并按该字段判定重试；保留文案匹配作为兼容旧渲染端的回退。🤖 Prompt for AI Agents

重试路径使用与首次相同的
this.verifyDeadlineMs。DSH 在integrations/deepseek-harness/host-apply.mjs已将该值降到 10 秒，因此单次应用的最坏等待仍为约 20 秒，用户侧无进度提示。如果重试只用于「首帧已被预热」的场景，可为重试使用更短的期限，例如
Math.min(this.verifyDeadlineMs, 8_000)，以限制总时长。🤖 Prompt for AI Agents

Inline comments:
In `@apps/tray/session-host.mjs`:
- Around line 55-101: Update parseImportMode and parseThemeApplyInput so every
invalid-input error uses the existing badRequest mechanism or otherwise carries
statusCode 400, including errors from inline parseImportMode calls in the image
and video apply handlers. Preserve the current validation messages and
successful parsing behavior.
In `@integrations/deepseek-harness/cli.js`:
- Around line 308-313: Update linkPluginIntoProfile and uninstall to use
fs.lstat when checking plugin links, so dangling symlinks are detected even when
their targets are missing; remove any existing link entry before creating or
uninstalling, while preserving the same-target early return behavior.
In `@integrations/deepseek-harness/client.js`:
- Around line 1593-1601: 修正心跳及 applyModes 中对 acknowledgeRender 的调用，传入已提交视频槽位
data-bc-video-ready 的真实布尔状态，而不要依赖 videoReady 的默认值 true；保留封面阶段为未就绪，并仅在首帧实际呈现后报告
ready，同时覆盖 settleCommittedVideo 失败后继续保留封面的情况。
In `@integrations/deepseek-harness/gallery-host.mjs`:
- Around line 238-244: Extend the client-disconnect handling around importTheme
so an abort that occurs after downloads complete prevents the theme import from
starting or committing; check clientAbort.signal.aborted immediately before the
import and propagate the existing abort behavior. Keep the current cancellation
wiring for fetch and downloadToFile unchanged.
- Around line 89-101: Throttle the onProgress calls in the download Transform
used by the pipeline so progress updates are reported only after a meaningful
time or percentage change, rather than once per chunk. Preserve size-limit
enforcement and ensure the final progress reaches completion; update the callers
that serialize these callbacks only as needed to support the throttled behavior.
In `@integrations/deepseek-harness/gallery.js`:
- Around line 109-142: 在 integrations/deepseek-harness/gallery.js 的 load() 和
open() 中加入 try/catch，将请求失败信息写入 msg；open() 失败时清空 grid 后返回。同步更新
integrations/deepseek-harness/console.js 的对应调用，使 void
window.BeauticodeGallery.open() 通过 .catch() 调用 showMessage 展示错误。
Apply the same fix in `@integrations/deepseek-harness/console.js` around lines 431

In `@integrations/deepseek-harness/host-apply.mjs`:
- Line 11: Increase the /reapply request timeout beyond the current 30-second
limit so ApplyTransaction can complete its potentially unbounded import,
staging, and rollback work before the request expires; update the timeout
configuration used by /reapply, not DSH_VERIFY_DEADLINE_MS, which only governs
DshSession verification.
In `@packages/core/src/media-source.ts`:
- Around line 5-8: Update resolveMediaSource to enforce basename-only filenames
for managed sources before joining with ownerDir, rejecting or otherwise
preventing any source.file containing path traversal segments; use the existing
path utilities and preserve local-source handling. Also strengthen isManifest so
managed sources are accepted only when source.file equals
path.basename(source.file), ensuring all saved-manifest callers share the same
boundary validation.
In `@packages/core/test/background-store.test.js`:
- Around line 102-107: Resolve the fixture image and video paths with
fs.realpath before the assertions in the background-store tests, then compare
activeImagePath and loadedImage.input.imagePath against the resolved image path
and the corresponding video assertions against the resolved video path. Keep the
existing saveCurrentTheme and loadSavedTheme behavior unchanged.

When DSH loads /__beauticode/client.js, the leading < makes the entire script fail to parse with SyntaxError: Unexpected token '<'. Consequently the bridge client never connects or renders backgrounds, and all browser-side apply acknowledgements fail; the DSH plugin tests that evaluate this script fail for the same reason.

There was a problem hiding this comment.
When a profile already has the correct beauticode-dsh link specification and still contains the legacy @beauticode/dsh-plugin dependency, this removes the legacy property only from the in-memory object; the unchanged early return at line 196 then skips writing package.json. The installer therefore leaves the obsolete dependency on disk, allowing a later package install to recreate the legacy plugin copy that this migration is intended to remove.

There was a problem hiding this comment.
When an image is applied and saved through the new atomic flow, this assigns null instead of the saved theme ID. The console immediately refreshes from status.themeId, so it clears the just-selected image theme, stops marking it with aria-current, and shows a generic current-background label; video themes do not have this problem because their ID is retained.

There was a problem hiding this comment.
When a stale control, session-host, or tray-claim file refers to a PID that the OS has reused, this loader never finds isRecordedPidLive: none of the three candidate core modules exports that function in this repository. It therefore returns null, and isLiveRecordedPid falls back to the PID-only check, treating the unrelated process as the recorded tray/session and potentially routing requests to stale control data or refusing to start the in-process session.

There was a problem hiding this comment.
When an approved gallery skin has a display name containing a character forbidden by saveCurrentTheme—for example Cyberpunk: Neon—this forwards that name unchanged after downloading all media. The atomic import then fails at theme persistence and rolls the applied background back, so otherwise valid skins with common punctuation cannot be installed; apply the same illegal-character normalization used for local filenames before starting the import.
