+- [x] **T14 解密内容默认不打控制台日志(2026-08-20 完成)** - `console_log.meshtastic` 默认改 false(新部署);install.sh 模板同步;README 注明调试可显式开启。既有配置显式写 true 的不受影响
-- [ ] **T15 session cookie `Secure: true`** - 生产部署 HTTPS 下设置 `session_secure: true`(`install.sh:94` / config 默认值);确认 nginx 强制 HTTP->HTTPS 跳转
+- [x] **T15 session cookie `Secure: true` 默认(2026-08-20 完成)** - config 默认与 install.sh 模板改 `session_secure: true`(HTTPS 部署适用);纯 HTTP 部署需显式改回 false;README 注明

+- [x] **T16 config.yaml 回写权限(2026-08-20 完成)** - `config.Write` 改 0600,配置文件含明文口令仅属主可读 ✓(冒烟验证)

-- [ ] **T18 bot PSK 不回显** - `internal/bot/admin_bot_routes.go:308` 改为 `psk_set` 布尔,与 forwarder 路由风格一致
+- [x] **T18 bot PSK 不回显(2026-08-20 完成)** - bot DTO 改 `psk_set` 布尔;`UpdateBotNode` 空 PSK 保持原值(避免改配置时密钥被重置为 AQ==);前端编辑表单留空保持不变 ✓(冒烟验证)
