  "summary": "Reviewed the ARM assembly implementation of the SHA-256 block routine, including the ARMv4, NEON, and hardware-accelerated paths plus their control-flow transitions. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation/deobfuscation pipelines, or persistence/tampering behavior.",
