W16: close CRITICAL/HIGH findings, integrate metadata gate, complete audit summaries (W16.1-W16.6)
- W16.1 (曹武): F-11.7-1 CLOSED — confirmed W12.4 fix, corrupt binary eliminated
- W16.2 (孙宇): F-11.1-1 FIXED — context_plugin.cpp try/catch on set_max_tokens + on_shutdown
- W16.3 (陈风): F-11.1-2 CLOSED — confirmed W12.1 fix, strdup OOM protection already in place
- W16.4 (胡桐): Integrate check_agents_metadata into refresh_status.py as pre-gate (error→exit 1)
- W16.5 (周岩): Add Findings Summary to W13.3 network audit, register 3 findings
- W16.6 (赵码): Add Findings Summary to W13.1+W13.2 AI audits, register 8 findings (4 already W14-fixed)

Build 0 error, ctest 4/4 pass, metadata check 0 error 0 warning.

8年应用安全经验背景是渗透测试 + 代码审计。
熟悉 OWASP Top 10、CWE 分类、内存安全漏洞模式。
对 C/C++ 的常见漏洞缓冲区溢出、UAF、整数溢出有专精。
偏好:威胁建模在写代码之前。
communication_style: 漏洞清单 + CVSS 评分
strengths:
- 内存安全审计
- API 密钥 / 凭证管理
- 输入验证 / 反序列化
- 威胁建模
weaknesses:
- 对功能开发节奏感知较弱,容易"挡路"
- 偶尔过度强调低风险问题

确认 build/dstalk-cli/dstalk-cli.exe 已删除 (W12.4 devops-hu 修复);
build/bin/dstalk-cli.exe 为唯一正确副本 (67584 bytes);
cmake --build build --config Release: 0 error; ctest: 4/4 pass。

event: "W2.2: api_key 在 on_shutdown 时安全清零 (deepseek + anthropic)"
rating: done
detail: |
在 deepseek_plugin.cpp 和 anthropic_plugin.cpp 的 anonymous namespace 内
新增 secure_zero(void*, size_t),通过 volatile 写零循环对 g_cfg.api_key
执行安全擦除后 clear。编译0 error 0 warning与改动相关的文件

event: "W9.3: 错误日志凭证泄露审计8文件0真实漏洞"
rating: done
detail: |
审计了 8 个文件的所有 host->log / printf / fprintf(stderr) / std::cerr 调用。
0 真实可利用漏洞。deepseek/anthropic 的 configure 日志有意排除了 api_key
build_headers_json() 产生的凭证字符串仅通过内存传递给 Beast HTTP未经过日志管道。
低风险/假阳性 2 项lsp server_cmd 日志 + network e.what() 异常信息),无需代码修改。
审计报告写入 docs/explanation/security-logging.md。CVSS: N/A无可利用漏洞

event: "W13.5: session + tools 联合安全审计 (515行)"
rating: done
detail: |
联合审计 session_plugin.cpp (264行) + tools_plugin.cpp (251行)。
TOP3: (1) tools L50/L85 路径遍历→任意文件读写 (CVSS 7.5);
(2) 两插件全文 static global 无 mutex→多线程竞态 UAF/NPD;
(3) session L127/L141/L204/L242 + tools L106/L132/L203
缺 try/catch→§8违反→std::terminate。
凭证泄露: session_save 明文落盘含 tool_calls_json(潜在token泄露)。
命令注入: 未发现。路径遍历: tools 确认。
评级 session:D+ / tools:D。

event: "W14.3: 修复 W13.5 审计发现 — 路径遍历 + 全局状态加锁 + 9 vtable try/catch"
rating: done
detail: |
修改 session_plugin.cpp (294行) + tools_plugin.cpp (292行)。
(1) is_safe_path() 拒绝空路径、绝对路径(/或盘符)、含..段lexically_normal二次校验
builtin_file_read(L50) 和 builtin_file_write(L85) 入口调用不安全→log ERROR + 返回错误JSON。
(2) 加锁: session g_history/g_cached_history→g_session_mutex; tools g_tools→g_tools_mutex;
g_host/g_file_io→std::atomic<T*> load(acquire)/store(release)。
(3) 9 vtable try/catch 覆盖: session_add/save/load/history (session) +
tools_register_tool/unregister_tool/get_tools_json/execute/on_init (tools)。
编译: cmake --build build --config Release → 0 error 0 warning。
ctest -C Release → 4/4 pass。
