Key Highlights

  • Model-driven parallel sub-agent spawning with max_depth limits
  • TUI Sub-agent real-time monitoring panel
  • Hot/Cold memory separation with memory_search
  • Unified context budgeting and structured compression
  • Web Settings configuration page for context compression

New Features

  • spawn_subagents tool for concurrent attack exploration
  • Automatic archiving of large tool outputs to cold memory
  • Structured context compression with sensitive field masking
  • Web UI for managing compression and memory settings
  • English contribution guide (CONTRIBUTING_EN.md)

Full Release Notes

## Highlights

- **模型驱动并行子 Agent 扇出** — `spawn_subagents` 工具让主模型一轮内并发探索多个独立攻击方向；子证据合并回父状态统一重分配 eNNN，带完整生命周期预算与安全上限（max_depth 硬顶 2）
- **TUI 子代理实时监控面板** — 私有 JSON 行协议实时展示每个子代理角色/状态/步数/进展，独立 run_id + 事件 token 防旧 worker 污染
- **冷热记忆分离** — 热上下文默认 48 条 / 32K token，超出自动归档到冷记忆 JSONL 分片，`memory_search` 按需检索；大工具输出自动归档为指针+预览
- **统一上下文预算与结构化压缩** — `prepare_context()` 唯一预算入口覆盖全部 LLM 路径；70% 触发、55% 目标的结构化压缩生成确定性 `[context digest v1]`，敏感字段脱敏，审计事件完整记录
- **工具循环上下文重构** — 稳定前缀 + 可变工具循环尾部，仅在超高水位时压缩；流式调用 `asyncio.to_thread` 避免阻塞兄弟 agent
- **Web Settings 配置页** — 支持上下文压缩与记忆配置的 UI 管理
- **英文贡献指南** — 新增 CONTRIBUTING_EN.md（issue #157），服务国际贡献者
