bisect 全 case FAIL(含无 hardening baseline 与 seccomp=unconfined)+ 宿主
overcommit/ulimit 数据干净 → 嫌疑收敛为 trixie chromium 150 构建 × 本宿主
组合本身跑不了。round-3 脚本:
1/2. 抓崩溃真实 FATAL 行(此前被 head 截断)+ gdb backtrace(best-effort)
3.   实测 Google 官方 chrome-headless-shell(npmmirror 下载)+ mmdc 接上出图,
     直接验证「镜像弃发行版 chromium、改装 puppeteer pinned headless shell」
     修法可行性,PASS 即定案动 Dockerfile

+- **07-11 / 0.58.5**:**chromium 秒崩 round-3 探针**:bisect 结果全 case FAIL(含 baseline 无 hardening、seccomp=unconfined)→ hardening 全部无罪,宿主 overcommit/ulimit 数据也干净——嫌疑收敛为 trixie chromium 150 构建 × 本宿主组合本身跑不了。新 `deploy/sandbox/probe_chromium_round3.sh`:①抓崩溃 FATAL 行(此前日志被 head 截断)+ gdb backtrace(best-effort);②实测 Google 官方 chrome-headless-shell(npmmirror 下载,puppeteer 生态对着它测试)在本宿主能否跑 + mmdc 接上出图——直接验证「镜像弃发行版 chromium 改 pinned headless shell」修法可行性,PASS 即定案动 Dockerfile。
 - **07-11 / 0.58.4**:**mermaid 崩塌第二根因排查工具 `deploy/sandbox/probe_chromium_bisect.sh`**:pids-limit 1024 部署后复测(同 task 9dcae061,green 实例全新容器)仍首调秒崩——排除 pids 打满,根因在 hardening flag × chromium 150 交互。探针把线上 docker run 全款 hardening 逐 flag 开关(no-new-privileges / read-only / cap-drop / mem·cpu / seccomp=unconfined),每 case 跑 mmdc + 裸 chromium 两条,忠实复现 exec 路径(--user zcbot + HOME=/tmp),尾部带判读表;RUN.md 故障兜底条目同步。
 - **07-11 / 0.58.3**：**admin 用量表默认时间范围 all→近7天**：`admin.js` 「按模型」「各用户用量」两表初始 range 从"全部"改"近7天"（下拉仍可切全部/30天）；API 端 `range` 默认值不动。
 - **07-11 / 0.58.2**:**sandbox `pids_limit` 256→1024,修容器内 mermaid 渲染必崩**(task 9dcae061 排查):DB 全量扫描证实近 90 天 mmdc 渲图 0 成功(26 次 launch fail + 67 次 timeout),根因 `--pids-limit` 把线程也计数——chromium headless 一次启动 ~150-200 线程,叠加 shell 超时只杀 host 侧 docker CLI、容器内 mmdc+chromium 树残留(executor_docker 已知 Cancel limitation),256 打满 → `pthread_create EAGAIN` → chromium SIGTRAP(dbus 报错是干扰项)。改 agent.yaml + pool.py 默认值两处;RUN.md 故障兜底补条目。**待服务器验证**:重启 web + 容器回收后跑 `probe_mermaid.sh`,若 chromium 150(07-08 镜像重建带进)仍秒崩则另查宿主 docker/seccomp;彻底修法是 Step 3b PGID kill 协议(超时清残留),此次未动。附带 4 个 diag 脚本(scripts/diag_task_9dcae061.py 等)未入库。**unifyllm 文本模型再加 2 个进 pro 档**——`gpt55`(gpt-5.5)/`gpt54_mini`(gpt-5.4-mini),参数照 gpt56_sol 模板(temp 硬约束 1.0),mini 档 tool_calling/code_quality 记 good、max_iterations 100;网关 `GET /v1/models` 确认模型 ID + diag 冒烟(tool-calling)两模型均过 + `ModelCapabilities.load` 线上路径验证;`diag_unifyllm.py` 默认清单 5→7 个(RUN.md 同步)。
