+# NoteConnection v1.7.0
+
+## English
+
+### Release Scope
+
+- Compare baseline: `v1.6.8..v1.7.0`
+- Release focus:
+  - startup performance acceleration rollout closure
+  - multi-platform startup validation automation
+  - roadmap consolidation for next-stage learning-system evolution
+
+### Highlights
+
+- Completed the startup acceleration loop with phase-2/3/4 runtime behavior upgrades:
+  - delta tick transport for startup simulation updates
+  - low-alpha adaptive startup throttling policies
+  - staged edge rendering and startup overlay flow hardening
+- Added strict warm-start snapshot validation guardrails:
+  - fingerprint consistency checks
+  - snapshot age and topology consistency checks
+  - coverage threshold checks before applying persisted layout
+- Added frame-coalesced tick application on the main thread to reduce redundant repaint pressure during startup stabilization.
+
+### Startup Performance and Validation Pipeline
+
+- Extended startup performance tooling with:
+  - baseline/pilot compare report generation
+  - cross-platform matrix report generation
+  - real-time watch mode for strict gate evaluation
+  - no-hardware signoff pipeline using Windows real logs plus simulated cohort gates
+- Preserved release safety boundaries by explicitly separating:
+  - engineering signoff (no-hardware acceptable)
+  - release signoff (requires real macOS/Android/iOS cohorts)
+
+### Runtime Contract and Documentation Sync
+
+- Synced runtime contract references in Diataxis docs for new startup profile fields and tick summary telemetry.
+- Updated bilingual startup acceleration explanation docs with v1.1 optimization and risk-guardrail closure details.
+- Added the next-stage knowledge-mastery evolution roadmap docs and integrated them into Diataxis nav and mapping.
+
+### Version Metadata
+
+- Aligned release metadata to `1.7.0` in:
+  - `package.json`
+  - `package-lock.json`
+  - `src-tauri/tauri.conf.json`
+
+### GitHub Release Body Template (Ready-to-Use)
+
+Use this section as the GitHub Release description body with minimal edits:
+
+1. Summary:
+   - This release closes the startup performance acceleration rollout and upgrades startup reliability guardrails.
+2. What is new:
+   - low-alpha adaptive delta transport
+   - frame-coalesced startup tick apply
+   - strict warm snapshot validation
+   - automated startup compare/matrix/signoff pipeline
+3. Operational note:
+   - Engineering signoff can proceed with no-hardware flow, but release signoff still requires real multi-device cohort evidence.
+4. Docs:
+   - Runtime contracts and startup acceleration docs are synchronized in bilingual Diataxis references.

+
+### 发布范围
+
+- 对比基线：`v1.6.8..v1.7.0`
+- 本次发布重点：
+  - 启动性能提速方案收口
+  - 多平台启动验证自动化链路补齐
+  - 下一阶段学习系统演进路线文档固化
+
+### 版本亮点
+
+- 完成启动提速 Phase 2/3/4 运行时行为升级：
+  - 启动期 Delta Tick 传输
+  - 低 alpha 自适应限流策略
+  - 分阶段边渲染与启动遮罩链路加固
+- 补齐 Warm Snapshot 严格校验护栏：
+  - 指纹一致性校验
+  - 快照时效与拓扑一致性校验
+  - 应用前覆盖率阈值校验
+- 在主线程引入启动期 Tick 帧级合并应用，减少稳定阶段冗余重绘压力。
+
+### 启动性能与验收流水线
+
+- 启动性能工具链扩展为：
+  - baseline/pilot 对比报表
+  - 多平台矩阵报表
+  - 准实时严格门禁 watch 模式
+  - 无多端硬件场景下的工程签收流水线（Windows 真实日志 + 模拟 cohort 门禁）
+- 保留分层签收边界：
+  - 工程签收可接受 no-hardware 流程
+  - 发布签收仍要求真实 macOS/Android/iOS cohort 证据
+
+### 运行时契约与文档同步
+
+- Diataxis 参考文档已同步新增启动 profile 字段与 tick summary 观测契约。
+- 双语启动提速解释文档已补齐 v1.1 优化与风险护栏收口内容。
+- 新增“知识彻底掌握演进路线”文档，并接入 Diataxis 导航与映射体系。
+
+### 版本元数据
+
+- 以下文件版本已统一到 `1.7.0`：
+  - `package.json`
+  - `package-lock.json`
+  - `src-tauri/tauri.conf.json`
+
+### GitHub Release 正文模板（可直接使用）
+
+可将以下内容直接作为 GitHub Release 正文，并按需微调：
+
+1. 概要：
+   - 本版本完成启动性能提速方案收口，并强化启动期稳定性护栏。
+2. 核心新增：
+   - 低 alpha 自适应 Delta 传输
+   - 启动 Tick 帧级合并应用
+   - Warm Snapshot 严格校验
+   - 启动 compare/matrix/signoff 自动化流水线
+3. 运维说明：
+   - 工程签收可走 no-hardware 流程，但发布签收仍需真实多端 cohort。
+4. 文档说明：
+   - 运行时契约与启动提速文档已在双语 Diataxis 体系内完成同步。
