Adds a Learning Path for deploying live MobileSAM segmentation on Alif Ensemble E8 with ExecuTorch and Zephyr. It follows the 384×384 four-prompt int8 model through export, firmware memory checks, model and firmware programming, live-camera validation, and troubleshooting.

Review the lessons in navigation order, then the bundled sample patch and OSPI recovery writer. The setup uses released PyTorch 2.13.0, TorchAO 0.18.0, and TorchVision 0.28.0. The Learning Path and its child pages remain marked as drafts pending a fresh firmware build and board run with this dependency setup.

Validation passed: the full site build with Hugo 0.130.0, repository metadata checks, all 19 shell blocks, and a fresh Python 3.12 source installation. The complete four-prompt export passed the unchanged quality gate using the original deployment calibration image, followed by the PTE/JSON tensor-contract checks. The resulting program has no CPU operators and requires 5,898,256 bytes of temporary scratch, within the configured 6,488,064-byte pool. The export lesson now requires an explicit calibration image because the bundled dog image fails this configuration's quality gate.
