## Problem and outcome / 问题与结果
Self-hosting currently requires assembling a Server installation, while App port mappings can use the wrong external port or remain active after cancellation. This phase adds a verified Linux x64 Server image and Compose recipe, and repairs the existing NAT-PMP dependencies so mapping results, cancellation and cleanup follow the gateway response and request lifetime.
The image wraps the exact verified Server archive and is tested before publication. Version tags retain their original image; `latest` follows the latest published GitHub release. The two scoped dependency replacements retain upstream source, tests and licenses, with their removal criteria documented in `internal/thirdparty/README.md`.
Planned release: **v1.3.0** (compatible Docker distribution feature plus NAT fixes).
## Release notes
### 中文
- 新增 Linux x64 Docker 镜像与 Compose 部署方式，内置网页、信令和 STUN，可按需开启 SFU 兜底。提供部署、更新与备份教程。
- 修复 App 的 NAT-PMP 端口映射：正确使用路由器分配的外部端口，并在关闭时尝试删除映射。
- NAT-PMP 请求会随取消或超时结束，避免连接尝试结束后继续在后台重试。
已有配置和房间数据格式保持兼容，更新无需迁移。
### English
- Added a Linux x64 Docker image and Compose setup with the Web UI, signaling, STUN and optional SFU fallback, plus deployment, update and backup guides.
- Fixed App NAT-PMP mappings to use the external port assigned by the router and attempt mapping removal on shutdown.
- NAT-PMP requests now stop on cancellation or timeout, preventing retries from continuing after a connection attempt has ended.
Existing configuration and room data formats remain compatible; no migration is required.
## Verification / 验证
[Candidate CI](https://github.com/TNTcraftHIM/Piik/actions/runs/34761969362) passed for `1d8de6c4690434cd2cf44fbdee4f45b1776432fa`. The final two files changed after that run are documentation only (`docs/todo.md` and `docs/verification-status.md`), with repository hygiene checked separately.
- Web type checks, unit tests and production build; Go core tests, vet and target builds; NAT and media-edge race detection.
- Actual packaged-image checks with Docker Compose: production startup, embedded Web, UDP STUN, optional SFU startup, retained room authority across recreation, diagnostic ZIP export, non-root/read-only execution and clean shutdown.
- Windows x64, Linux x64 and macOS arm64 App packaging.
- Scoped NAT dependency regressions cover assigned ports, renewal, deletion, cancellation, lost replies and PCPv6 composition using real local UDP endpoints.
The publishing pipeline reruns the image checks for the merged release revision. First publication also requires making the GHCR package public and checking anonymous pulls of its version and `latest` tags. Representative physical routers, public-media networks and operator-specific HTTPS/firewall settings remain outside the container smoke test.
## Impact / 影响
No signaling, native-control or storage-format change. Existing App/Server installations remain compatible. Docker supports `linux/amd64` in this phase; its default is P2P, and SFU remains an explicit deployment option. Existing deployments keep their configuration.
README, bilingual self-hosting guides, container maintenance, versioning, dependency provenance and NAT evidence are updated. Completed feedback is removed from TODO; ongoing network evidence remains tracked there.
## Problem and outcome / 问题与结果
Machines with several local addresses could fail before opening Piik, and startup or connection failures were difficult to diagnose. This phase adds Local invitation-address selection and accessible diagnostics, preserves useful startup errors, and repairs media preparation and recovery without changing room authority or routing policy. It also aligns language handling, playback, public downloads and contributor documentation with the resulting behavior.
## Release notes
### 中文
- **多网卡也能正常选择启动方式。** 本地房间在需要时显示网卡名称与局域网地址，供你选择朋友所在的网络；公网邀请和连接已有站点不再因多个局域网地址而无法启动。
- **更容易排查启动和连接问题。** 启动页新增“诊断启动”，同时记录 App 与网页诊断；网页版也有独立诊断入口。启动失败会显示具体原因和重试方法，Windows 双击启动后的错误会停留等待确认。诊断模式下异常退出会保存报告，ZIP 由用户自行保留或清理。
- **减少连接准备中的无谓等待。** 普通候选发现不再等待可选端口映射；修正连接重启时旧候选与完成通知的处理，以及部分准备失败后的反馈。Native 媒体连接可在网络支持时使用 IPv6 直连，同时保留 IPv4 路径。
- **修正分享恢复中的状态问题。** 切换画面后重新计算首播保护所需的新帧；SFU 恢复时应用最新画质设置；一次应答发送失败不再使整个会话失去 Native 接收能力。密码错误提示也进行了去重。
- **改善播放与全屏交互。** 同步 Safari 原生全屏中的播放、音量与退出状态；可操作的视频画面显示手形光标。

**测试范围：** 主要验证 Windows App 与桌面浏览器。macOS、Linux 实机采集和移动端、跨公网 IPv6 的更广泛验证仍待完成，欢迎试用反馈。
### English
- **Choose how to start on machines with multiple network addresses.** Local rooms show interface names and invitation addresses when a choice is needed. Public invitations and connections to an existing Site no longer fail because several LAN addresses are available.
- **Diagnose startup and connection problems more easily.** The launcher now offers Debug launch for both App and browser diagnostics, alongside a separate browser diagnostics control. Startup failures include their cause and retry guidance; Windows errors remain visible for confirmation after a double-click launch. Failed exits in diagnostic mode save a report. Exported ZIPs remain available until you move or delete them.
- **Remove unnecessary connection setup waits.** Ordinary candidate discovery no longer waits for optional gateway mapping. Fixes cover stale candidates and completion signals during ICE restarts, and feedback from failed connection preparation. Native media can use direct IPv6 connections where available while retaining IPv4 paths.
- **Keep sharing recovery aligned with the current source and settings.** Source changes count new frames for startup protection, SFU recovery uses the latest quality preferences, and one failed answer submission no longer disables Native receiving for the entire session. Duplicate password-error feedback has also been removed.
- **Improve playback and fullscreen interaction.** Safari native fullscreen now synchronizes playback, volume and exit state. Interactive video surfaces show a pointer cursor.
- **Align language selection and community translation guidance.** Simplified and Traditional Chinese system locales select Simplified Chinese; other systems default to English. Chinese, English and visual-mode shortcuts remain, with bilingual translation guides and a registration path for additional languages.
- **Simplify release downloads and refresh the website.** Release attachments contain the three App ZIPs and the Server runtime archive; source identity and checksums appear in a collapsed section of the release notes. The website keeps its embedded introduction and adds a standalone viewing link, with updated setup, download and operations guidance.
**Upgrading:** Extract the complete App ZIP for your platform and keep its directory structure. Follow the deployment guide for Server upgrades, preserving existing configuration and SQLite data. Existing wire contracts and storage formats are unchanged.
**Test coverage:** Windows App and desktop browsers are the primary validated paths. Physical macOS/Linux capture, broader mobile coverage and IPv6 across separate public networks remain open; testing and feedback are welcome.
## Verification / 验证
- `npm run check`: PASS, including TypeScript, 807 tests in 60 files and the production Web build.
- `npm run check:client`: PASS on Windows, including Go formatting/tests/vet, Windows/Linux core builds and native Windows capture compile/probe. Darwin requires the native macOS CI runner.
- `npm run gate:client-media`: PASS with Chrome 152 and a real captured test window on Windows. Two receivers obtained video and audio; live and paused profile changes, recovery frames and cleanup passed. This is a single-machine test, not a public-NAT success-rate measurement.
- `npm run gate:client-link`: PASS using the newly packaged Windows App. A separate remote machine fetched its temporary public page and completed the WebSocket upgrade; App exit closed the link and cleanup passed.
- Server runtime and Windows App candidate packaging: PASS, including archive identity/checksums and execution from the extracted App ZIP. Native Linux/macOS package checks still run in the publishing pipeline before publication.
- `node scripts/check-docs.mjs`, `scripts/check-project-state.ps1`, `git diff --check` and `npm run build:website`: PASS. Seven documentation-size gardening advisories and the existing Vite chunk-size advisory remain non-blocking.
- Browser review: English/Chinese website setup and direct-download links, narrow layout and diagnostics/language controls checked. Native popover accessibility correctly exposes expanded/collapsed state without a duplicate attribute owner.
- Independent audit found no P0/P1/P2 issues; focused race checks for portmapping and mediaedge passed. Diagnostic archive accumulation is retained by the owner's explicit choice. The currently unreachable language menu placement issue is a first-community-language prerequisite in TODO.
Physical macOS/Linux capture, broader mobile behavior, restricted-network/endurance coverage and cross-network Native IPv6 remain explicitly outside this candidate's evidence.
## Impact / 影响
Compatible feature release, planned as v1.2.0 from v1.1.2. Browser/server v23, Native control v9, capture v7 and SQLite schema 2 remain unchanged. No new telemetry service, retry policy or configuration requirement is introduced. Public Demo remains open-entry and P2P-only. NAT-PMP dependency corrections are explicitly deferred to the next release and are not claimed here.
The existing product, configuration, translation, research and operations owners were updated. Raw audits, handoffs, diagnostic logs and experimental sources are excluded from the PR.
Some room-entry failures still replaced the existing comics with standalone icons in Chinese and English, and status help required a touch hold. These pages now share the same illustrated scenes with localized explanations. Help-only indicators use native buttons and the shared Tooltip owner for click/tap, hover, keyboard and dismissal; action controls retain their actions and long-press guidance.
The App preselects public invitations when no Site is saved, while retaining a saved Site's priority. Launcher metadata and its consumer agree on the existing link mode. The release guide now requires explicit owner approval of each planned version and complete notes before publication.
## Release notes
### 中文
- 补齐中英文的房间错误页、等待状态和操作提示图解，纯视觉模式继续保留。
- 电视下方状态、连接指示灯和说明提示支持点击或轻触展开；再次点击、点外部或按 Esc 可关闭，悬停和键盘操作继续可用。
- App 未保存站点时默认选中“公网邀请”，已保存站点仍优先显示。
- 统一无音频图标，并完善系统“减少动态效果”设置下的显示。
### English
- Completed illustrated guidance for room-entry errors, waiting states and controls in Chinese and English. Pure-visual mode remains available.
- Picture status, connection indicators and informational notices now open on click or tap. Click again, tap outside or press Escape to dismiss; hover and keyboard guidance remain available.
- The App now preselects public invitations when no Site is saved. A saved Site retains priority.
- Made no-audio icons consistent and improved presentation with the system's reduced-motion setting.
## Verification
- `npm run check`: TypeScript, 59 test files / 776 tests and the production Web build passed.
- `npm run check:client-core`: Go tests, formatting, vet and supported local target builds passed; native macOS packaging remains on its macOS runner.
- Existing Launcher HTTP tests verify both the public-link default and saved-Site priority. The browser checked both corresponding metadata responses.
- 27 focused browser checks passed for native touch events, short tap, long press, drag cancellation, action preservation, keyboard dismissal and 260/390px entry layouts.
- 46 overlay combinations passed across Chinese, English, pure-visual mode and 260/390/1280px, including keyboard playback and reduced motion.
- A real local Server returned the missing-room state correctly in all three modes. Status-control accessibility checks, documentation and repository hygiene passed.
Compatible patch. No signaling, native-control, capture or storage contract changes. Existing physical device/network deferrals remain in force.
## Problem and outcome / 问题与结果
App startup rejected short or non-ASCII site passwords, viewers lacked picture-click playback gestures, and text-mode hints hid the existing illustrations. This phase accepts site passwords verbatim, combines shared illustrations with localized captions in tooltips and stage overlays, and adds desktop single-click play/pause and double-click fullscreen through the existing playback owner. Pure-visual mode remains available.
App ZIP names are now stable per platform, allowing the website to use GitHub's native latest-download URLs. The App update link selects the ZIP matching its compiled OS and architecture from the checked release metadata, falling back to the release page if the package is unavailable. Verified Gitee links retain their explicit release version. The Windows packaging workflow also stops restoring a redundant Go toolchain cache that caused setup-go to fail.
## Release notes
### 中文
- 中英文操作提示和画面状态覆盖层加入动态漫画，说明更直观；纯视觉模式继续保留。
- 观众可单击画面暂停或继续播放，双击进入或退出全屏；触屏仍通过单击显示或隐藏播放栏。
- 修复设置短密码、中文密码时 App 或 Server 无法启动的问题。站点密码仍可留空。
- 官网各系统的 GitHub 下载按钮直接获取最新 ZIP 包，并保留 Gitee 备用下载线路。
- App 内的更新入口直接下载对应系统和架构的 ZIP 包。
### English
- Chinese and English tooltips and picture status overlays now pair concise explanations with animated illustrations. Pure-visual mode remains available.
- Viewers can click the picture to pause or resume and double-click to enter or exit fullscreen. Touch taps continue to show or hide playback controls.
- Fixed App and Server startup rejecting short or non-ASCII site passwords. Site passwords remain optional.
- Each platform's GitHub download button now fetches the latest ZIP package, with Gitee retained as an alternative download source.
- App update links download the ZIP matching the installed platform and architecture.
## Verification / 验证
- `npm run check`: 59 test files / 774 tests, TypeScript and production build passed.
- `npm run check:client-core`: Go tests, formatting, vet and supported local target builds passed for the included runtime changes. Native macOS packaging remains on its macOS runner.
- Desktop and 390px touch playback checks passed, including double-click without an intermediate pause and control/keyboard interaction.
- Illustrated tooltip checks passed in Chinese, English and pure-visual modes, light/dark themes, 260/360/390px layouts, keyboard, touch hold and reduced motion. User accepted the resulting UI.
- Real stage overlay components passed 46 checks across the three modes and 260/390/1280px layouts, including keyboard play activation, reduced motion, and no overlay over healthy playback with a quality limitation.
- Bounded release review confirmed JSON password authentication retains old bodyless Bearer compatibility and ZIP names match packaging, publisher, mirror and website consumers.
- After checking both providers' real API shapes, 27 focused update tests and type-checking passed; anonymous GitHub and Gitee metadata each selected all three actual platform ZIPs without downloading them.
- Documentation, repository hygiene and diff checks passed.
## Impact / 影响
Compatible feature release. Signaling, Native control, capture protocol and persistent room schema are unchanged. The new latest-download filenames must be published before the matching website deploys; the existing CI-to-Website sequence provides that order. Production service updates use the immutable Server artifact and bounded rollback. Broader physical macOS/Linux, network and endurance acceptance stays under the existing documented deferrals.
## Problem and outcome
Website visitors can download the usual Windows x64, macOS Apple silicon
and Linux x64 App packages directly from clearly labeled platform cards.
Each card includes a verified Gitee alternative, with shared setup
guidance and a More downloads link for the full release list. The
homepage reuses the application's 20 bilingual greetings, and the sample
game no longer displays an invented title.
Website builds resolve links from the latest published GitHub release
and validate matching mirror assets. Website deployment follows main CI
so newly published packages reach the next site build. Version selection
and release notes now share a product-change filter: standalone website,
documentation and maintenance changes do not create App/Server releases
or affect the next product version.
## Verification
- `npm run check`: 57 test files / 759 tests, TypeScript and product
production build passed.
- Website build passed with real GitHub/Gitee v1.0.0 metadata and with
the explicit local fallback.
- English and Chinese browser checks at 390px and 1440px passed:
platform links, More downloads, greeting selection and language
switching.
- All 23 website film check groups passed; the final shared artwork
change rebuilt successfully.
- Documentation, repository hygiene and diff checks passed. Real
Git-history tests cover product/website mixtures and moves across the
release boundary; the accepted phase plans `publish: false`.
## Impact
GitHub remains the version authority; Gitee is a download mirror.
Unavailable mirror metadata falls back to its release page. Product
runtime behavior and package compatibility are unchanged. Physical
macOS/Linux capture and broader device/network limits remain documented.
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]
* fix: allow Linux interface discovery in embedded media service
* feat: expand local diagnostic reports
* research: validate independent Browser encoding producers
* feat: prototype Browser pool ownership and record remaining media gates
* feat: refine Browser shared encoders and native output reuse
* Refine carrier costs and simplify release entry points
* Close media phase and prepare piik design handoff
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.
Merged after local full validation and production postflight. GitHub CI's 16 Linux locale assertions are pre-existing and unrelated to this infrastructure-only change; see PR comment.
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.
Modularize durable truth, bound always-loaded instructions, and keep domain-document size checks advisory. Local cross-platform repository hygiene checks pass; GitHub-hosted steps were not started because of the account billing state.
