顺序:`trip_review` → **Panda(C3 DOS)** → SecOC/指纹 → 摄像头/进程 → 车型
## 侧栏 NO PANDA / Panda 离线(C3 DOS)
1. `panda_status` — `pandaStates`、`usb_all`、`multi_panda`、`pandad_snapshot`
2. `list_all_pandas` — 双 USB(如内置 F4 + 外接红熊)时查 `heterogeneous_f4_h7`
3. `panda_recovery_hint` — 含 USBErrorBusy / 崩溃循环建议
4. `grep_log` — `pandad|panda|xhci|USBErrorBusy|DOS internal`
5. offroad:`tsk_restart_pandad(confirm=true)`
6. 双 Panda 崩溃 → `rebuild_pandad(confirm=true)` + `reboot_device`
7. 仍失败且为 F4 → 技能 **`c3-dos-panda`**:`flash_panda_firmware` 或 `recover_dos_panda(confirm=true, internal=true)` / `external=true`(外接黑熊)
8. **不适配 C3/DOS/黑熊**(缺 `panda.bin.signed`、`unknown HW`、双 Panda 指纹失败)→ `ai/docs/PANDA_C3_F4_PORTING.md`:三层合入 `panda@7d703710`、`sp@43d4f56f`、`opendbc@3244efe` → `scons` + 刷写
9. **刷写后 GUI 仍 Panda 否** → 重启 manager(pandad 被 kill 后 manager 不会自动重建子进程)
**禁忌**:F4 不要用 H7 固件;见 `ai/docs/PANDA_FLASH.md`。
## Lite C3(无功放)
若 `get_host_environment` / `get_sp_device_hw` 显示 `lite: true`(`device_type` 为 `tici`):
1. **不要**依赖 `soundd` 或驾驶员监控(`dmonitoringd`)——Lite 上这些进程不启动。
2. 需要声音反馈时:`set_sp_dev_beep(true)`,确认 onroad 后 `beepd` 运行(`SpDevBeep=1`)。
3. **勿**写入 `RecordAudio`、`AlwaysOnDM`(`params_policy` 会拒绝)。
4. UI 设置列表中 `lite_unavailable` 项可忽略。
丰田/雷克萨斯:`lookup_secoc_tier` + TSK 工具链。

Build reusable Terraform modules for AWS, Azure, and GCP infrastructure following infrastructure-as-code best practices. Use when creating infrastructure modules, standardizing cloud provisioning, or implementing reusable IaC components.
Wire a service's OpenTelemetry output to Sematext Cloud. Walks through region, App-type, instrumentation flow (managed OTLP endpoint vs Sematext Agent), and signal selection (traces/metrics/logs), then produces the exact env-var block and points at a runnable reference example in this repo. Invoke when instrumenting a new app for Sematext.
Deployment workflows, CI/CD pipeline patterns, Docker containerization, health checks, rollback strategies, and production readiness checklists for web applications. Use when setting up deployment infrastructure or planning releases.
Watch a pull request or review cycle until it is ready to merge. Use when asked to babysit, monitor, or keep checking PR comments, reviews, and CI until all actionable issues are resolved.
Interact with the Paperclip control plane API for task coordination and governance. Use when checking assignments, updating issue status, posting comments, delegating work, managing routines, or calling Paperclip API endpoints.
