• [Claude Cowork Deep Compaction, Adaptive Desktop Patching & Zero-Diff Token Estimation] Break Context Window Exhaustion Bottlenecks, Implement Adaptive Recursive Patching, and Strictly Align with Official Tokenizer (PR #3580, PR #3582, Fixes #3576, Thanks to @cubelikeplayDaniel):
  • Adaptive Recursive Traversal & Version Priority: Introduced find_claude_apps_recursively to automatically penetrate nested random-hash subdirectories in newer Claude Desktop builds (e.g. 2.1.286/f2326db61802/claude.app); coupled with parse_semver to prioritize official production instances over sandbox builds.
  • macOS System-Level Integrity & Safe Isolation: Resolved folder-permission crash issues after patching by verifying valid Bundle metadata (Info.plist), preventing kernel crashes (tccd/syspolicyd); backups are strictly isolated in .deep_compact_backups/ outside the App Bundle to preserve Gatekeeper seals; applied chmod 0o755 and recursive ad-hoc re-signing via codesign --force --deep --sign -.
  • Alarm State Machine & 35k Active Context Diet: Eliminated hardcoded num_msgs <= 10 deadlocks, setting error target caps to 20k tokens to guide clients in trimming history while returning 200 OK; prioritized manual ./compact dispatch with strict mutual locking against auto gates.
  • Token Estimation Canon Aligned with Official Specification: Reverse-engineered client-side token counting routines, pinning high-res images to 2000 tokens (small images 258); intercepted Base64 media inside tool_result to prevent inflated token counts; eliminated redundant safety margins, matching official /context readings.
  • Cross-Platform Parity & Type Safety (PR #3582): Hardened conditional compilation and type signatures for non-macOS platforms (Windows / Linux), eradicating platform isolation warnings and guaranteeing uniform cross-platform builds.
  • Frontend UX & Progressive Decoupling (AgentSettings.tsx): Replaced high-risk warnings with an elegant "Experimental" badge; introduced a two-step standard ModalDialog clarifying the boundary between switch-only mode and full patch mode, plus ./compact guidance; kept fully opt-in with zero intrusion for default users.
  • Long-Term Architectural Specification (PR #3582): Shipped docs/CLAUDE_COWORK_DEEP_COMPACT_SPEC.md based on official 50% thresholds (100k) and measured latency gains, covering end-to-end sequence flows, decompiler AST comparisons, physical offset and padding formulas, and obfuscation tracking scripts.

• [Claude Cowork 深度归档闭环、客户端自适应补丁与官方 Token 估算绝对对齐] 突破 Claude 桌面端上下文膨胀瓶颈，实现自适应版本穿透微创补丁与官方 0-diff 计词对齐 (PR #3580, PR #3582, Fixes #3576, Thanks to @cubelikeplayDaniel):
  • 自适应递归穿透与版本优先探测: 引入 find_claude_apps_recursively，自动穿透新版 Claude 桌面端嵌套的随机 Hash 子目录（如 2.1.286/f2326db61802/claude.app）；结合 parse_semver 进行语义数值比较，确保正式生产环境实例优先于本地沙盒测试版本。
  • macOS 系统级完整性与安全隔离机制: 彻底解决打补丁后请求文件夹权限闪退问题，严格校验合法 Bundle 元数据（防止沙盒缺失 Info.plist 时请求权限导致 tccd/syspolicyd 内核强退）；备份文件统一部署在 App Bundle 外部隔离目录 .deep_compact_backups/，杜绝破坏 Gatekeeper 密封性；写入补丁后强制赋予 chmod 0o755 并执行 codesign --force --deep --sign - 递归重签名。
  • 假报警状态机与 35k 活跃上下文瘦身: 废除硬编码 num_msgs <= 10 判定死锁，将报错目标上限设定为 20k tokens，驱动客户端足额削减历史并回显 200；手动 ./compact 穿透优先调度并与自动门禁机制绝对互锁。
  • Token 算力法典与官方 0-diff 绝对对齐: 逆向对齐官方客户端底层计词调用链，多模态高分辨率图片统一固定折算为 2000 tokens（小图 258）；在 tool_result 中精准识别 Base64 媒体拦截，防止图片被误当纯文本虚增数万 tokens；剔除虚高安全余量，文本与紧凑工具 Schema 估算与官方 /context 完美拟合。
  • 跨平台兼容与类型安全强化 (PR #3582): 针对非 macOS 平台（Windows / Linux），完善补丁扫描与路径探测的条件编译与类型标注，彻底消除平台隔离警告，确保全平台构建一致性。
  • 前端交互与渐进式解耦架构 (AgentSettings.tsx): 移除高危警告标签并标注为“实验性功能 (Experimental)”；引入双步标准 ModalDialog（说明“仅开开关原生折半”与“配合补丁深度瘦身至 35k 以下”的安全边界，并提供 ./compact 极简使用指南）；默认 Opt-in，保障全平台用户无感与零侵入。
  • 长效架构规范白皮书 (PR #3582): 随版本沉淀永久技术架构文档 docs/CLAUDE_COWORK_DEEP_COMPACT_SPEC.md，基于官方 50% 门限（100k）与实测延迟优势全面阐释深度瘦身原理，涵盖完整时序图、反编译 AST 源码对比、物理偏移与等长填充公式及混淆定位脚本。
