ExecuTorch Tribal Knowledge Base

Synthesized from 2,200+ GitHub issues and 99 discussions. Covers backends (QNN, XNNPACK, Vulkan, CoreML, Arm, Cadence), export, quantization, and troubleshooting.

Mode dispatch: If .wiki/fb/skill-internal.md exists, read it for additional modes. Parse the first token from $ARGS case-insensitively — if it matches a mode defined there, run it. Otherwise, run query mode below.
