Based on SOC occupation classification
Hidden stage for magnetar. Assemble validated AXMODEL, SDKs, reports, and usage documentation into a customer delivery directory.
Convert remote or local AI models into AXera AXMODEL packages with Python and C++ SDKs for customer delivery. Use when Codex must acquire a model from Git/HuggingFace/URL/local path, export ONNX, compile with Pulsar2, simulate/validate AXMODEL accuracy, optionally run on AX hardware, generate SDKs, or package deployment artifacts.
Hidden stage for magnetar. Compile static ONNX to AXMODEL with Pulsar2 and record compile artifacts.
Hidden stage for magnetar. Export the acquired model to static-shape ONNX, validate it against the source model, and generate model_meta.json plus calibration data.
Hidden stage for magnetar. Acquire a remote or local model into TASK_DIR/origin without modifying the source.
Hidden stage for magnetar. Generate customer-facing Python and C++ inference SDKs from model_meta.json and AXMODEL artifacts.

目标：确认 Pulsar2 可用，并根据 TARGET_HARDWARE 准备 C++ SDK 所需的 BSP 或交叉编译工具链。
PULSAR2_BIN > PULSAR2_IMAGE > PATH 中的 pulsar2 > Docker 镜像。AXERA-TECH/Pulsar2 拉取镜像（使用 hf-mirror）。pulsar2_command。根据 TARGET_HARDWARE 选择 BSP 下载地址和 AX runtime 路径：
| 芯片 | BSP 来源 | 内容 |
|---|---|---|
| AX650 | AX650 BSP SDK V3.10.2 | 含 aarch64 交叉编译器 + AX runtime (include/ lib/) |
| AX620E | Arm GNU 裸工具链（待更新为BSP） | 仅交叉编译器，AX runtime 需另行提供 |
