      "summary": "Reviewed the Hexagon assembly implementation of `hexagon_memcpy_forward_vp4cp4n2`, which is a forward `memcpy` routine using looped word/doubleword loads and stores plus `l2fetch` prefetching. No concrete malicious or supply-chain indicators were found; I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and none were present.",

      "summary": "Reviewed a Hexagon assembly `memcpy` helper that copies aligned buffers in 8-byte chunks and falls back to `memcpy@PLT` when alignment checks fail.
