主题 · Theme — 下载加速通道重做、文件重命名与目录删除、系统级通知、主题切换动画。 Download acceleration channels reworked, file rename & directory delete, real system notifications, animated theme switching.

新增 · Added

  • 下载加速通道（重做）· Download acceleration channels, reworked 独立条目 + 单个总开关 + 通道列表：内置通道（HTTPS，开发者自建）与任意多个自定义通道，单选生效；自定义通道可随时移除，内置不可删。
    A dedicated entry with a single master switch and a channel list: one built-in HTTPS channel plus any number of custom channels, single-select; custom channels can be removed at will, the built-in one cannot.

  • 协议与显式同意 · Agreements with explicit consent 「外来服务自负责任协议」（自定义通道）与「内置通道安全声明」（内置通道）两份文本，均带版本号；未同意当前版本无法开启总开关，同意后记录版本号 + 时间戳作为凭据，文本升版需重新同意。
    Two texts — Third-party Service Disclaimer (custom channels) and Built-in Channel Security Statement (built-in channel) — each with a version number. The master switch cannot be turned on before consenting to the current version; consent stores version + timestamp as evidence, and a version bump requires re-consenting.

  • 文件重命名 · File rename 长按文件 → 重命名，内容不变；一次原子提交（新增新路径 + 删除旧路径），新路径同样走路径校验；.gitkeep 不允许重命名。
    Long-press a file to rename it without touching its content, performed as one atomic commit (add new path + delete old path). The same path rules apply, and .gitkeep cannot be renamed.

  • 目录删除 · Directory delete 长按目录 → 删除目录：先枚举其下全部文件，再在一次提交中删除；结果被截断或超过 200 个文件时拒绝并提示分批，绝不静默半删。
    Long-press a directory to delete it: all files are enumerated first, then removed in a single commit. If the listing is truncated or exceeds 200 files the operation is refused with a hint to split the batch — never a silent partial delete.

  • 系统级通知 · Real system notifications 接入 flutter_local_notifications：后台与 allChannels 通知改为真正发系统通知（Android / Windows / Linux / macOS / iOS）；发送失败只留痕，并回退到「落盘 + 回前台补发」。
    Integrated flutter_local_notifications: background and allChannels notices are delivered as real system notifications on Android / Windows / Linux / macOS / iOS. Failures are recorded and fall back to “persist + re-deliver on return to foreground”.

  • 主题切换动画 · Animated theme switching 换明暗 / 换主题色不再硬切（themeAnimationDuration）；系统关闭动画时自动置 0，与既有规则一致。
    Switching light/dark or the seed colour is no longer a hard cut (themeAnimationDuration). When the system disables animations the duration becomes 0, consistent with existing behaviour.

变更 · Changed

  • 自定义通道地址必须是 HTTPS 且以 / 结尾；明文 http:// 会被直接拒绝并说明原因。
    Custom channel URLs must be HTTPS and end with /; plain http:// is rejected with an explanation.
  • 内置通道地址更新为 HTTPS（https://server.344977.xyz:9999/）；此前的明文地址会被 Android 9+ 拦截。
    The built-in channel now uses HTTPS; the previous cleartext address was blocked on Android 9+.
  • 生效条件固定为「总开关打开 且 已同意当前版本协议」，否则一律直连。
    Acceleration only takes effect when the switch is on and the current agreement is consented to; otherwise downloads always go direct.

修复 · Fixed

  • 定位并消除 4.4.0 下载故障的根因：加速通道只有明文 HTTP，被 Android 9+ 拦截（Cleartext HTTP traffic not permitted）——本版改为 HTTPS 后从机制上不再依赖被拦截的传输。
    Root cause of the 4.4.0 download failure found and removed: the channel only spoke cleartext HTTP and was blocked on Android 9+. With HTTPS in place this class of failure can no longer occur.
  • 新增单元测试 test/surface/path_rules_test.dart（路径规则 / 空文件 / .gitkeep / 通道地址 / 地址拼接 / 协议区分）。
    Added unit tests covering path rules, empty files, .gitkeep, channel URLs, URL joining and agreement selection.

已知限制 · Known limitations

  • 多语言（R6）尚未落地：界面仍为中文，已排入 4.9。
    Localisation (R6) is not shipped yet — the UI is still Chinese; scheduled for 4.9.
  • 不支持目录重命名与跨目录批量操作（当前仅单文件重命名 + 目录删除）。
    No directory rename and no cross-directory batch operations yet (only single-file rename and directory delete).
  • 5.0 待办：下载多线程与进度/速度动画、页面过渡卡顿、Actions 长日志加载、通知中心图标与展开动画、安卓返回键统一处理。
    Planned for 5.0: multi-threaded downloads with progress/speed animation, page-transition jank, long Actions logs, notification-centre icons & expand animation, unified Android back-key handling.
