Wave 10: deep audits of 5 unaudited plugins, smoke regression set (W13.1-W13.6)

- W13.1 anthropic_plugin (architect-yang, 497 lines): rated C. 6 C ABI
  functions lack try/catch (§8 violation); my_chat leaks response_body on
  error path; tool_use response silently dropped.
- W13.2 deepseek_plugin (engineer-sun, 486 lines): rated C+. 7 ABI entries
  unprotected including json::parse paths (malformed JSON terminates);
  SSE [DONE] sentinel match brittle; ~55% code overlap with anthropic
  suggests an ai_plugin_base extraction.
- W13.3 network_plugin (qa-wang, 322 lines): rated C. CRITICAL: TLS
  certificate verification fully disabled (set_verify_mode never called,
  default verify_none accepts any cert) — all AI traffic incl. api_key
  is MITM-vulnerable. DNS resolve has no timeout; catch lacks (...).
- W13.4 lsp_plugin (architect-huang, 749 lines): rated C. CRITICAL:
  guaranteed deadlock at L519-526 → L547 (g_lsp_impl_start holds mutex
  then calls g_lsp_impl_stop which re-locks the same non-recursive
  mutex); 7 vtable funcs unprotected; server→client requests dropped.
- W13.5 session+tools (security-cao, 264+251 lines): rated D+/D. Path
  traversal in builtin_file_read/write (zero validation); global
  static state in both plugins lacks mutex (UAF risk); 9 vtable funcs
  lack try/catch.
- W13.6 smoke regression (qa-xu, +193 lines): 4 new cases — context
  max_tokens trim, config dual-store consistency (exposes that W12.2
  merge is incomplete: dstalk_config_set→config_service.get returns
  null), HTTP error path no-crash, repeated init/shutdown cycle.

Verified: cmake build 0 error 0 warning, ctest 4/4 pass.

Top W14 priorities surfaced: TLS verification (W13.3), LSP deadlock
(W13.4), file-tool path traversal (W13.5), config dual-store still
broken (W13.6 R2), shared try/catch wrapper across all AI plugins.

2026-05-27	W2.2: api_key 在 on_shutdown 时安全清零 (deepseek + anthropic)	done	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）。

2026-05-27	W9.3: 错误日志凭证泄露审计（8文件，0真实漏洞）	done	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）。
