• [Cowork Auto-Compaction Decoupling, Binary Pruning Trap Bypass & Context Residual Cleanup] (PR #3615, Fixes #3614, Thanks to @cubelikeplayDaniel):
  • Precise Cowork vs Code Mode Decoupling: Removed false-veto rules on generic CLI headers (x-app: cli, x-claude-code-session-id) and wrapper host headers (claude-desktop-3p), resolving missed Cowork compactions in Claude Desktop; tightened Code mode detection strictly to mcp__ccd_* tools and "You are Claude Code" prompt markers. (Thanks to @cubelikeplayDaniel)
  • Bypass Client Binary Halving Fallback Trap: Identified the decompiled client CHt fallback where large token gaps trigger Math.floor(n / 2) (preserving 277 turns / 145.7k tokens); introduced calculate_cowork_pruning_target with a calibrated positive gap (+500 tokens) to bypass halving and compel full history summary down to baseline. (Thanks to @cubelikeplayDaniel)
  • Remove Lifetime Continuation Exemption Deadlock: Eliminated hardcoded !is_continuation_detected gate exemption, fixing the issue where a session remained exempt forever once "This session is being continued..." was injected, swelling to 320k+. (Thanks to @cubelikeplayDaniel)
  • 180s Streaming Timeout Guard: Extended summary distillation timeouts to 180s to prevent network disconnects during heavy context compression. (Thanks to @cubelikeplayDaniel)
• [Full-Chain Compaction Signature Stripping, Experimental Global Strip & Tri-Scheme Anti-Resurrection Shield] (PR #3615, Fixes #3614, Thanks to @cubelikeplayDaniel):
  • Physical Cache Invalidation on Compaction: Connected clear_session_for_compaction across Claude handler lifecycles to physically flush RAM ThinkingStore, SQLite proxy_db, and SignatureCache, eliminating pre-compaction stale signature leaks. (Thanks to @cubelikeplayDaniel)
  • Protocol-Differentiated Sentinel Isolation: Compaction history locks Gemini tool calls with official bypass sentinels (skip_thought_signature_validator), while strictly stripping signatures for Claude targets (downgrading thoughts to <think> text) without inventing sentinels, eliminating 400 validation failures. (Thanks to @cubelikeplayDaniel)
  • New Experimental Toggle for Global Compaction Stripping: Added enable_global_compaction_strip in Thinking Budget settings, default disabled for 100% normal user non-interference; when enabled, applies client-agnostic and protocol-agnostic protection.
  • Tri-Scheme Coordinated Anti-Resurrection Architecture: Coordinates macro watermark drop detection (purges caches and defines boundary on context collapse), micro folding detection (flags [Output truncated], [Result omitted] in-place prunings), and anti-resurrection shields (suppresses initial_session_sig and blocks Phase 3/4 fuzzy text matching).

• [Cowork 自动压缩触发与判定解耦、规避二分修剪保底并封堵上下文残留] (PR #3615, Fixes #3614, Thanks to @cubelikeplayDaniel):
  • 精确解耦 Cowork 与 Code 模式判定: 消除对通用 CLI 标头（x-app: cli / x-claude-code-session-id）及第三方宿主外壳标头（claude-desktop-3p）的一票否决，彻底解决 Claude Desktop 原生 Cowork 请求被误杀为 Code 模式导致漏拦截的问题；严格收敛 Code 模式判定为 mcp__ccd_* 专属工具或 "You are Claude Code" 声明。 (Thanks to @cubelikeplayDaniel)
  • 规避客户端二分保底与深度压缩调优: 针对客户端 CHt 倒算算法中大 Gap 触发 Math.floor(n / 2) 导致保留 277 条历史残留 145.7k tokens 的问题，新增 calculate_cowork_pruning_target 抛出微小正向差额（500 tokens），跳过客户端折半保底陷阱，促使客户端将历史轮次深度打包摘要压缩至基线水位。 (Thanks to @cubelikeplayDaniel)
  • 移除静态接续标记终身免死租约: 移除门禁硬编码的 !is_continuation_detected，解决 Cowork 会话在首次压缩后因首条消息永久留存 "This session is being continued..." 导致后续轮次获得终身免死、暴涨至 320k 均不再被拦截的严重缺陷。 (Thanks to @cubelikeplayDaniel)
  • 长流摘要 180s 超时保护: 为摘要生成请求配置 180s 延长超时保护，防止复杂工程长上下文摘要提炼时因网络波动异常断流。 (Thanks to @cubelikeplayDaniel)
• [压缩全链路签名治理、试验性全局压缩剥离与三案联动防复活机制] (PR #3615, Fixes #3614, Thanks to @cubelikeplayDaniel):
  • 全链路物理清库调用与生命周期回收: 在 Claude 消息流生命周期与摘要生成处补齐 clear_session_for_compaction 物理调用，确保会话压缩时 RAM ThinkingStore、SQLite proxy_db 与 SignatureCache 真正被级联清空，杜绝失效旧签名穿透残留。 (Thanks to @cubelikeplayDaniel)
  • 协议差异化出站哨兵隔离: 针对压缩历史轮次，Gemini 缺失签名的工具调用统一以官方哨兵 skip_thought_signature_validator 锁定防止 400 校验报错；Claude 目标彻底剥离签名（思考正文降级为 <think> 纯文本出站），严禁向 Claude 发明 Gemini 哨兵，保证多模型全协议兼容。 (Thanks to @cubelikeplayDaniel)
  • 新增「全局压缩剥离签名」试验性开关: 在思维预算设置中新增 enable_global_compaction_strip 开关，默认保持关闭（100% 保持既有行为与普通用户零干扰）；开启后全局生效，扩展为协议无关、客户端无关的通用压缩防护。
  • 三案联动防复活架构: 开启后联动执行宏观高水位线检测（字符量/轮次断崖暴跌时物理清库并划定治理边界）、微观就地折叠检测（识别 [Output truncated]、[Result omitted] 等定向隔离受污染历史）与防复活屏障（在 finalize 中彻底压制 initial_session_sig 回填，并在 restore 中先划定边界再加载记录，杜绝 Phase 3/4 模糊前缀匹配复活）。
