+Use the R14 release-candidate report when you need a business-facing answer about what is ready, what is preview-only, and what still needs online evidence:
+
+```text
+docs\reports\2026-07-10-r6f-r14-release-candidate.md

+Current short answer:

+- 已完成：搜索联系人、搜索群组、收消息基础读取、收文件列表。
+- 可预览：发消息 preview、发文件 preview。

+runs\send-sandbox-gate-package.zip
+runs\send-file-sandbox-gate-package.zip
+```
+
+They are generated under ignored `runs\` and are not committed.

 - If `win_helper_version` fails, rerun `powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-win-helper.ps1` first.
