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.

Features
- Watch without installing. Friends join by invitation in a desktop or mobile browser.
- Share from Piik App or an existing Piik site. Choose a screen, window, browser tab or camera; available sources and audio depend on the platform.
- Direct connections first. Media travels between participants where possible (P2P). A self-hosted server can provide automatic media forwarding (SFU) as a fallback.
- Rooms you control. Invitations, room codes and optional room passwords, for one host and up to 20 viewers.
- Flexible viewing. Light and dark themes, playback controls, picture-in-picture and a connection topology view.
- One program to host a site. Web UI, room management and optional media forwarding are packaged together.

To share: download Piik App to get started. To share without installing, you can also create a room in the online version.
| Start here | What you need to do |
|---|---|
| Use Piik online | Share from a desktop browser, or choose Camera on a phone with browser camera support. |
| Download Piik App | Extract and open the App, choose Public invite, then Open Piik to create a temporary room. |
| Host your own site | Advanced: deploy Piik Server on a Linux x64 server with your own domain, then connect through Piik App or a browser. |
- Select Start sharing, then choose the picture and audio to share.
- Select Copy invite link and send it to your friends. Keep the sharing tab open.
Turn on the Microphone for commentary; its settings let you choose the input device and adjust your voice volume.
Piik follows your system language: Chinese or English, with English as the fallback. Use 中 / EN / ✦ in the header to switch language or try the visual mode. The App offers a local room, a temporary public link, or a connection to your own site. Keep the App running while sharing through it.

Browser capture requires HTTPS or localhost. Windows App and desktop browser
sharing are the primary tested paths. The macOS and Linux apps have not yet been
tested on physical devices; test results and feedback are welcome.
P2P-only modes, including the App's temporary public
link and the online version, may not connect on restrictive networks.
Self-hosting
Piik Server is a standalone binary with the web interface built in.
Download the Linux x64 Server package (piik-<revision>-runtime.tar.gz),
extract it, and run:
./piik-server
Open http://localhost:8787 to try it locally. For a public site, configure your
domain, HTTPS reverse proxy and STUN address. Room data is stored in SQLite.
For containers, use the Docker Compose setup.
