On AGNOS/aarch64, builds run natively. On laptops, builds use a Linux/ARM64 container.
--params builds libparams_c.so; --cereal builds cereal outputs; --panda
builds signed panda_h7 and body_h7 firmware only. Numeric jobs become -jN.
RELEASE and CERT are environment variables, not trailing SCons arguments:
  RELEASE=1 CERT=/path/to/certificate ./build --panda 4
CERT must name a readable certificate file. Omit RELEASE for DEBUG firmware.
--mapd explicitly packages the pinned offline Linux/ARM64 Go provider; it
does not fetch map regions or participate in the default build.
Run scripts/laptop_device_build.sh doctor to check local prerequisites.
Full laptop builds require a source-matched QCOM artifact package in
.cache/qcom-artifact-package; device builds still compile models natively.
--check-startup checks retained settings admission read-only using the local
native developer runtime. Supply a matching Params namespace and recovery
storage. A relocated copy can fail its path-bound profile marker.
