+## [1.4.3] - 2026-05-23
+
+### Changed
+
+#### Dashboard and Global UI Polish
+
+- **Balanced dashboard chart cards** - aligned the Hourly Distribution card and Top Apps card heights for a cleaner two-column layout
+- **Refined app-wide visual style** - added layered ambient background gradients, enhanced glass-card depth/hover behavior, and shell-level decorative light effects across main pages
+- **Typography refresh** - upgraded the global font stack for better readability in both Chinese and English UI surfaces
+- **Full-width page layout for key modules** - removed fixed max-width constraints on Categories, Goals, and Focus Mode pages so content fills the available main area without a large right-side blank zone
+
+### Fixed
+
+- **Hourly distribution overflow bug** - fixed per-hour aggregation so usage segments are split across hour boundaries, preventing impossible values such as single-hour totals over 60 minutes
+- **UWP app identification on Windows** - improved foreground window resolution to avoid reporting UWP apps as `ApplicationFrameHost` or `Unknown` by resolving the real process behind the frame host window
+

+# TimeLens Roadmap (From v1.4.3)
+
+Last updated: 2026-05-23
+
+## Starting Point
+
+Current stable baseline: **v1.4.3**
+
+Existing foundation already in place:
+
+- Local-first desktop time tracking with SQLite
+- Widget Center with official widgets and third-party widget loading
+- Permission and bridge-key based extension integration
+- Data Health, Backup/Restore v2, and cross-platform startup controls
+
+## Product Direction After v1.4.3
+
+- Keep local-first as the default architecture.
+- Upgrade from "data display" to "action guidance".
+- Grow widgets into a practical daily workflow system.
+- Make extension and widget ecosystem safe, observable, and stable.
+
+## Milestones
+
+## v2.2.0 (2026 Q3) - 小组件爆发期
+
+### 主题目标
+
+把 Widget Center 做成真正高频入口。
+
+### 核心功能
+
+- 小组件商店页升级：分类、搜索、推荐、最近使用。
+- 组件组合场景：晨间面板、专注面板、复盘面板，一键启用布局。
+- 组件状态同步：同一组件多实例支持独立配置模板。
+- 组件性能监测：CPU/内存占用可视化、异常自动降级。
+
+### 新增官方小组件（第一批）

+- 单日平均打开组件次数提升 40%。
+
+## v2.4.0 (2026 Q4) - 深度专注与目标执行
+
+### 主题目标
+
+把洞察变成“可执行计划”。
+
+### 核心功能
+
+- Focus Plan：基于历史行为自动生成今日专注计划。
+- Goal Coach：目标拆分、风险提示、延期建议。

+- 目标达成率提升 15%。
+
+## v2.6.0 (2027 Q1) - 开发生态与可扩展平台
+
+### 主题目标
+
+让第三方组件开发“易上手、可运营、可审计”。
+
+### 核心功能
+
+- Widget SDK v3：脚手架、热重载、调试面板。
+- 权限中心 v3：细粒度授权、按来源隔离、调用审计。
+- 本地 API 治理：限流、配额、错误分析、客户端信誉分。

+
+### 新增官方小组件（第三批，偏开发与效率）
+
+- Code Focus Heatmap（编码热力图）
+- Git Activity Summary（本地 Git 活动概览）
+- Build Monitor（构建状态）
+- Meeting Guard（会议防打断）
+- Context Switch Counter（上下文切换计数器）
+
+### 验收指标
+

+- 组件崩溃率下降 50%。
+
+## v3.0.0 (2027 Q2) - Local-First 生产力平台
+
+### 主题目标
+
+形成“仪表盘 + 行动系统 + 组件生态”的完整闭环。
+
+### 核心功能
+
+- Unified Workspace 2.0：洞察、计划、执行、复盘同屏联动。
+- Personal Automation：本地规则自动触发（时间、状态、应用场景）。
+- Data Lifecycle Pro：冷热分层、压缩、快速恢复。
+- Accessibility & i18n 全面补齐。
+
+### 新增官方小组件（第四批，平台级）
+
+- AI-Free Smart Assistant（纯本地规则助手，非云 AI）
+- Weekly Review Board（周复盘看板）
+- Time Budget Planner（时间预算）
+- Multi-Goal Kanban（多目标看板）
+- Life Balance Radar（生活平衡雷达）
+
+### 验收指标
+
+- 离线核心流程覆盖率 100%。
+- 首次启动到可用时间降低 30%。
+- NPS 与留存明显提升。
+
+## Widget Roadmap Matrix
+
+### Category Plan
+
+- Execution widgets: tasks, timers, planning, review
+- Focus-health widgets: break, water, stretch, recovery
+- Insight widgets: trends, anomaly, heatmap, category monitor
+- Developer widgets: coding sessions, build status, project rhythm
+- Ambient widgets: pet, quotes, lightweight motivation
+
+### Priority Recommendation
+
+- P0:
+  - Habits Tracker
+  - Quick Capture Inbox
+  - Calendar Agenda
+  - Goal Progress Ring
+- P1:
+  - Distraction Radar
+  - Focus Session Timeline
+  - Weekly Review Board
+- P2:
+  - Git Activity Summary
+  - Build Monitor
+  - Life Balance Radar
+
+## Release Gates (Every Version)
+
+- Performance gate:
+  - Widget open/render/memory limits are measured and enforced.
+- Security gate:
+  - Principle of least privilege for widget permissions.
+  - User can audit and revoke access at any time.
+- Reliability gate:
+  - Backup/restore compatibility passes for supported versions.
+  - Data integrity checks pass on upgrade datasets.
+- Local-first gate:
+  - Core journeys are fully usable when offline.
+
+## Scope Boundaries
+
+Still out of scope for this roadmap window:
+
+- Mandatory cloud account dependency for core features
+- Mandatory cloud sync for daily usage data
+- Uploading user behavior data by default
