v0.1.0 — Contribution City milestone

What's New

• Open a City view directly in GitHub profile contribution sections, with multi-year selection, gradual filling, pan, zoom and an expanded view.
• Use English or Simplified Chinese, with a saved browser-local language preference and a native extension Options page.
• Read daily contribution counts through the existing GitHub session. No token, separate account, developer backend, ads or telemetry.

Fixes & Engineering

• Yearly caches are scoped to the viewer and profile, with live identity checks, refresh and clear actions.
• Cancel loading and release the city when returning to GitHub's graph, hiding the page or navigating away; the renderer stops continuous frames when idle.
• Include the application icon, runtime artwork notices, bilingual store materials, and published homepage, support and privacy pages.

Deployment Notes

• This is the first GitHub milestone. Chrome Web Store submission is still under review, as confirmed by the maintainer; no verified store installation link is available yet.
• Download codeyears-0.1.0-city.zip, verify its SHA-256, extract it into a permanent folder, then load that folder as an unpacked extension in Chrome's developer mode. Open a GitHub profile and choose City.
• The attached ZIP is the frozen 0.1.0 candidate previously supplied for submission, not a rebuilt package. It has 79 files, 112,526,864 bytes, SHA-256 b0f004a227a68d8acce314343cf91cc053121a35ca09f009aa48106a99208018. The exact file uploaded to Google's console was not independently inspected.
• Edge, Terrain, Signature/Natural theme selection, and the compact fit/percentage/maximum toolbar are not part of this milestone. The compact toolbar is deferred to the next version; 0.1.0 retains its existing zoom buttons.
• Code is MIT-licensed; artwork and dependencies retain the separate terms in ASSETS.md and THIRD_PARTY_NOTICES.md.

Verification

• Existing release checks passed: build/type checks, package inventory, CRC, references, permissions, licenses and notices. The frozen package remains byte-for-byte unchanged.
• Local Chrome acceptance covers reinstall, default graph/City entry, contribution loading, cache actions, menus, language settings, expansion and native background cancellation/resume. User-performed browser-management and native Options steps are identified in the reports.
• Bilingual official/support/privacy pages and store media have their own verification records. These do not replace real extension or hardware acceptance.
• Edge, a full accessibility matrix, long-term memory/GPU/power budgets and a dedicated multi-account matrix were not verified. The maintainer explicitly removed dedicated account-isolation testing from this release scope; prototype 60 Hz observations are not a current City FPS claim.

新功能

• 在GitHub个人贡献区直接切换城市，选择多年范围，逐年填入地块，支持平移、缩放和页内展开。
• 英文与简体中文，可保存本地语言偏好，并通过扩展原生“选项”设置全局语言。
• 使用已有GitHub会话读取每日贡献数量，无Token、独立账户、开发者后台、广告或遥测。

修复与工程

• 年度缓存区分访问者和主页，使用前核对实时身份，支持刷新与清除。
• 切回原图、后台或离开主页时取消请求并释放城市，静止时停止连续帧。
• 正式图标、素材/依赖说明、双语商店媒体和已上线的官网、支持、隐私页面均有对应记录。

部署说明

• 本次是首个GitHub里程碑。Chrome Web Store仍在审核中，依据用户确认；尚无已核实的商店安装链接。
• 下载codeyears-0.1.0-city.zip并核对SHA-256，解压至长期保留的文件夹，再在Chrome开发者模式中“加载已解压的扩展”。打开GitHub个人主页后点击“城市”。
• 附件沿用提供给用户送审的冻结0.1.0候选，不重新打包：79文件、112526864 bytes，指纹如上。工具没有独立检查Google控制台实际选择的文件。
• Edge、Terrain、主题选择与新紧凑缩放组件不在首版范围；“全景图标｜比例｜最大图标”按用户决定放到下一版本，目前仍为原有缩放按钮。
• 代码MIT与素材/依赖条款分别管理，不能将代码许可解释为城市位图独立复用授权。

验证

• 已有构建、类型、ZIP清单/CRC/引用/权限/许可检查通过；本轮复核冻结包未变化。
• 本地Chrome已覆盖重新安装、默认原图、进入城市、数据与缓存操作、菜单、语言、展开，以及退出调试接管后的原生后台取消/恢复；报告区分工具与用户证据。
• 官网六个双语页面、媒体规格与示例数据标签均有独立检查，不冒充扩展或硬件验收。
• 未验证Edge、完整辅助技术矩阵和长期内存/GPU/功耗预算。专门多账户测试已由用户取消；不将历史3D原型60Hz记录迁移为当前City的帧率保证。
