## Problem and outcome / 问题与结果
This phase adds lightweight room interaction without making media depend on chat,
and adds Windows source-audio exclusion and optional SFU-only hosting at their
existing owners. It also corrects confirmed encoder/capture ownership and native
color-conversion defects. Host microphone commentary remains on the shared media
path; room voice and 4K are outside this phase.
## Release notes
### 中文
这是一次功能更新：Piik 加入了文字聊天与表情互动，并完善了 Windows 声音采集、画面颜色和自部署选项。
#### 新功能
- **边看边聊。** 在可移动、可缩放的聊天窗口中发送消息，或开启弹幕。停止分享后，房间中的朋友仍可继续聊天。
- **表情互动。** 点击沙发上的人物，给自己发表情，或把番茄等表情送给朋友；各端按同一事件显示动画。
- **排除应用声音。** Windows App 分享整个屏幕时，可排除一个应用及其子进程的声音，适合同时使用语音软件。所选应用退出后，来源声音停止，避免恢复为未过滤的系统声音。
- **可选的纯 SFU 模式。** 自部署管理员可让共享画面和声音统一通过媒体服务器转发。默认仍为优先 P2P；App 公网邀请保持纯 P2P。
- **Windows HDR 转 SDR。** 原生采集与缩略图自动将 HDR 来源转换为 SDR，沿用现有观看链路。
#### 修复与改进
- 修复原生颜色转换的范围与矩阵处理，避免已复现的暗部丢失、高光裁切和颜色偏差。
- 修复共享编码器切换时使用过期需求或过期帧信息的问题，保护正在观看的画面；修复换源后旧采集事件可能影响新来源的问题。
- 统一新控件、浮窗与来源选择文案，补充中英文使用说明。
#### 使用与升级
聊天与表情需要新版站点页面和 Server；声音排除需要新版页面与支持此能力的 Windows App。聊天只保留本页最近收到的消息，刷新后清空，不补发历史，且不提供端到端加密。
HDR 转换输出为 SDR，不代表端到端 HDR 或多声道支持。既有房主麦克风与立体声能力保留。
### English
This feature update brings text chat and reactions to Piik, alongside improvements to Windows audio capture, picture colors and self-hosting options.
#### New features
- **Chat while watching.** Send messages in a movable, resizable window, or enable on-screen chat. Friends can keep chatting after the host stops sharing.
- **Reactions.** Select a person on the sofa to react above yourself or send a tomato and other reactions to a friend. Participants animate the same shared event.
- **Exclude application audio.** When sharing a whole screen with Windows App, exclude one application and its child processes, useful when using a separate voice app. Source audio stops if the selected app exits, preventing a return to unfiltered system sound.
- **Optional SFU-only hosting.** Site operators can require shared video and audio to pass through the media server. P2P-first remains the default; App Public invite remains P2P-only.
- **Windows HDR-to-SDR conversion.** Native capture and source thumbnails automatically convert HDR sources to SDR for the existing viewing path.
#### Fixes and improvements
- Correct native color-conversion ranges and matrices, addressing reproduced crushed shadows, clipped highlights and color shifts.
- Correct stale demand and frame evidence during shared-encoder handoffs to protect the current picture. Prevent events from a replaced capture from affecting its successor.
- Align new controls, floating panels and source-picker copy, with updated Chinese and English guides.
#### Using this update
Chat and reactions require updated site pages and Server. Audio exclusion requires updated pages and a Windows App that supports the capability. Chat retains only recent messages received by the current page, clears on refresh and does not replay history. It is not end-to-end encrypted.
HDR conversion produces SDR; it does not add end-to-end HDR or surround sound. Existing host microphone commentary and stereo support remain available.
## Verification / 验证
- Web type checks, 78 test files / 1275 tests and production build: PASS.
- Go core tests, formatting/vet and target builds: PASS; Darwin cgo remains platform-limited on this Windows runner.
- Native build/check/color probes and synthetic HDR-to-SDR H.264/VP8 browser reception: PASS.
- Access/privacy gate, Native H.264 SFU-only media gate and local Auto/H.264 Host gate: PASS.
- Three real production pages: chat/reactions, stop/resume, idle-room join, host departure/return, offline draft recovery and invitation revocation: PASS.
- Synthetic parent/child process-audio exclusion and target lifetime: PASS; no raw audio retained.
- Windows candidate archive extraction and packaged Local startup/shutdown: PASS.
- Documentation and website build: PASS.
- [Candidate CI](https://github.com/TNTcraftHIM/Piik/actions/runs/36873766646) at
`f26cd208d03bc0dcbe353f8cac217f993216b0a3`: Go core and race checks, Web tests,
Server/container checks and Windows/macOS/Linux App packaging all PASS.
Publication was skipped as intended.
The owner accepted the UI/model and bounded local walkthrough for phase closure.
Physical HDR/mixed displays, mobile keyboard,
real voice applications across output devices and macOS/Linux capture remain
unverified. Existing field reports without matched evidence are not claimed
resolved. The owner authorized v1.7.0 publication on 2026-10-02. The final
documentation-only commit records that authorization; product code matches
the verified candidate above.
## Impact / 影响
Authorized version: **v1.7.0**, matching the local release planner. Current wire
contracts remain Browser/server 23, Native control 9 and capture 7. Optional
capabilities gate new functionality; existing room/media authority remains owned
by the existing services. No new ports, message persistence, room voice or
automatic room creation on page visit. Updated README, guides, standards,
research evidence and TODO stay with the candidate phase.
Public invitations could stop after an early tunnel-process exit, and connection progress and Viewer status did not consistently describe the current attempt or Host state. This maintenance release adds bounded startup retries, aligns enhanced NAT retry feedback across entry paths, and fixes camera-preview and room-entry layout.
The existing route owner and published contracts remain in place. Four-attempt progress is advertised and opted into; older readers retain supported messages. Interaction/chat experiments are outside this PR.
Validation: npm run check (74 files, 1072 tests and production build), npm run check:go (including Windows capture compile), documentation/repository hygiene, 10 production Viewer-entry discovery cases, and a real public-link gate with remote HTTP/WebSocket access and shutdown cleanup all passed. Existing device/network evidence limits remain documented.
## Release notes
### 中文
这是一次维护更新，重点改善公网邀请启动、连接重试反馈和分享状态提示，并修正两处界面布局问题。
- 公网邀请服务在连接就绪前意外退出时，会自动重试，最多重试 3 次；所有尝试仍共用 30 秒启动预算。
- 增强穿透连接在首次尝试失败后最多重试 3 次，重试进度显示为 1/3、2/3、3/3。邀请链接和房间号加入都支持新版进度提示。
- 修正观众状态提示：房主离线时不再误报“没有可用的媒体线路”，服务器连接恢复与媒体恢复也会分别呈现。
- 修正电视内房间号输入界面的居中位置，以及摄像头选择预览被裁切的问题。
- 尚未确认来源声音状态时，不再提前提示“未分享来源声音”。
本次保持现有版本兼容；新版重试进度需要页面与服务端均支持。额外重试不能保证所有网络都能直连。
### English
This maintenance update improves public invitation startup, connection retry feedback, and sharing status messages, with two layout fixes.
- If the public invitation service exits before connecting, Piik retries up to three times within the existing shared 30-second startup budget.
- Enhanced NAT traversal now allows up to three retries after the initial attempt, shown as 1/3, 2/3, and 3/3. Both invitation links and room-code entry support the updated progress display.
- Viewer status now distinguishes an offline host from an unavailable media route, and reports server reconnection separately from media recovery.
- Fixed the alignment of room-code entry inside the TV and cropping in camera-selection previews.
- The missing-source-audio notice now waits until the source's audio availability is known.
Existing version compatibility is preserved. Updated retry progress requires support from both the page and server. Additional retries cannot guarantee a direct connection on every network.
Waiting feedback and tooltips now share consistent presentation lifecycles, while App shutdown and native-media operation failures stay within their owning session or output. This phase also consolidates the project standards and publishes searchable English/Chinese reader documentation alongside the homepage.
Validation: repository hygiene and Markdown links; TypeScript, 971 Web tests and production build; website/documentation build; Go tests, vet and Windows/Linux builds with Windows capture checks; desktop/mobile UI and documentation review. Linux race, container and three-platform packaging checks run in the release pipeline. Physical macOS/Linux capture and broader network coverage remain outside this acceptance.
The owner approved v1.4.0 publication. Existing empty-source, Windows URL-handler and public-invitation timeout reports remain tracked; this release makes no claim to resolve those device/network reports. The Windows capture-border request is next-phase work.
## Release notes
### 中文
这是一次以稳定性和交互一致性为重点的功能更新。等待与提示更有反馈，App 启动、原生分享和连接恢复的边界处理得到改善，使用与部署指南也有了统一的文档中心。
#### 新增与改进
- 欢迎语、等待短句和六类可轮换的标签页标题共用一致的显示规则。等待短句从一开始就出现，并在停留时轮换；明确的错误与操作提示保持固定。
- 房间准入等漫画采用更克制的小人物与循环动效。改进 tooltip 的定位与指向，减少对播放器的遮挡；状态、图标和文案保持相同含义。
- 新增中英文文档中心，提供搜索、手机目录、使用教程、问题排查与自部署指南。官网 FAQ 聚焦开始使用前的问题，详细排查统一进入文档中心。
#### 修复
- 使用 `--local` 启动不再清空已保存的 Piik 站点地址。
- 打开系统浏览器不再阻塞 App 的退出流程；改进临时公网邀请、终端和诊断导出在关闭时的清理及错误反馈。
- 单条原生媒体连接的操作失败不再被误判为整个会话的协议错误；重复停止分享保持幂等。
- 修复连接替换、转发停止和异常退出时的部分资源清理问题，避免迟到结果影响当前连接。
- Windows 原生采集中，单个输出的编码错误只结束对应输出；共享采集源本身的错误仍会结束分享。
#### 升级与已知边界
本次保持现有协议版本与配置格式。更新 App 或自托管 Server 后，重新打开页面即可使用对应的新界面。
个别设备的空窗口列表、Windows 浏览器启动异常，以及 Linux 编码输出的故障隔离仍在跟进。macOS/Linux 的物理采集和更广泛的公网网络场景仍需实机验证；本次不宣称这些问题已经解决，也不承诺所有网络都能直连。
### English
This feature update focuses on stability and consistent feedback. Waiting states are easier to follow, App startup and native sharing handle several failure cases more reliably, and the new documentation center brings usage and deployment guides together.
#### New and improved
- Welcome lines, waiting captions and six groups of rotating tab titles follow one presentation lifecycle. Waiting captions appear immediately and rotate while visible; actionable errors and instructions remain fixed.
- Room-admission comics use restrained characters and looping motion. Tooltips point more accurately to their controls and interfere less with the player, with consistent meanings across illustrations, icons and copy.
- A new English/Chinese documentation center includes search, mobile navigation, usage guides, troubleshooting and self-hosting. The homepage FAQ covers questions before getting started and links to the documentation for detailed help.
#### Fixes
- Starting with `--local` no longer clears a saved Piik site address.
- Opening the system browser no longer blocks App shutdown. Temporary public invitations, the terminal and diagnostic exports handle cleanup and exit errors more consistently.
- An operation failure on one native media connection no longer becomes a protocol failure for the entire session. Repeated stop-sharing requests are safe.
- Fixed cleanup cases during connection replacement, relay shutdown and unexpected exits, preventing late results from affecting the current connection.
- On Windows, an encoder failure for one native output stops that output only. A failure of the shared capture source still ends sharing.
#### Updating and known limits
Protocol versions and configuration formats are unchanged. After updating the App or your self-hosted Server, reopen the page to use its updated interface.
Empty source lists on some devices, Windows browser-launch failures and Linux output-failure isolation remain under investigation. Physical macOS/Linux capture and broader public-network coverage still need device testing; this update does not claim to resolve those cases or guarantee a direct connection on every network.
Piik now has one public presentation and a coordinated App/Server release path. This phase unifies the room UI, rewrites the bilingual README and guides, adds a static website with an inline product film, and prepares matching GitHub/Gitee packages and update links.
The film uses the current homepage and shared product controls on one seekable timeline. Runtime fixes preserve presentation when the App opens a room, normalize Site origins, and keep capture and media-recovery status in the television indicator. New visits use Chinese for a Chinese system language and English otherwise; explicit language and visual-mode choices remain available. An optional site passphrase controls site entry, while room authorization remains enforced.
GitHub is the release authority. Gitee mirrors verified packages and provides update metadata when GitHub is unavailable. Reviewed PR release notes become the GitHub Release description. The separate public demo uses P2P only, with HTTPS and STUN verified.
Validation: 756 Web tests, TypeScript and production build; Go core tests, formatting, vet and available target builds; bounded Windows capture and App/Site interoperability; browser film checks, audible playback and narrow layouts; anonymous Gitee Windows-package download, checksum and launcher/update-link checks. Public demo acceptance covers authenticated WebSocket signaling, synthetic P2P video and room cleanup on one network. macOS/Linux physical capture and the wider device/network/endurance matrix remain explicitly deferred.
Publication builds every package from the merged source SHA. The repository is public, main protection is active, and Pages is configured for piik.tv. CI/publisher and Pages deployment records own publication results.

Windows App and desktop browsers are the primary validated paths. macOS and Linux have not yet been tested on physical devices; testing and feedback are welcome. The demo and App public invitations rely on P2P and may not connect on restrictive networks. Self-hosted sites can enable media forwarding.
Rename the active product, Go module, binaries, configuration, protocols and documentation to Piik while retaining the TV mascot and existing media/room behavior.
Use one current private contract without old-name aliases. Preserve SQLite authority and copy compatible local settings once; other settings start fresh. Git-message cleanup and the infrastructure name cutover are coordinated with this phase, with original history and deployment data archived externally.
Validated locally with Web and Go checks, Windows capture compilation, matched Client/Server builds, packaged Client control handshake and history-rewrite integrity checks. Skip duplicate hosted CI for this owner-authorized local release.
[skip ci]
Embed STUN and SFU in the shared Go process, reuse native encoding pipelines with independent adaptation, and complete Client lifecycle, settings, diagnostics and packaging fixes. Retain standard Browser senders after measured encoded-reuse limitations.
Complete the Native Client source/audio boundary, strict v5 loopback contract, Browser media lifecycle handling, and non-blocking release checks. Keep unverified platform/physical gates explicit; do not rewrite the Go Server.
Fixes the production-proven P2P-to-SFU quality misrouting. Local full checks and independent P0/P1 review passed; the GitHub job did not start any steps.
Implements the accepted opt-in native-edge local convergence controller and the pre-share topology optimization and peer-only policies. Local full checks and independent P0/P1 reviews passed; the GitHub job did not start any steps.
Implements the accepted memory-resident room and access model on the single piik-v8 Browser wire. Local repository, full Web, build, and Chrome access/privacy gates passed before merge.
Preserve exact selected edges across unrelated route revisions, demote corroborated bad relay parents, and parameterize the bounded endpoint cap while retaining the production default of two.
Web Hosts can set local display names through the existing opt-in presence roster; Viewer/Host subscribers see the current Host name. Native exact wire remains unchanged.
