{
  "summary": "Reviewed the PowerPC64 assembly implementation of GHASH/GCM routines (`gcm_init_p8`, `gcm_gmult_p8`, `gcm_ghash_p8`). It appears to be normal generated crypto code and I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or payload execution.\nReviewed the target ARM assembly file, which implements P-256 Jacobian point doubling and related bignum helper macros using local arithmetic only. I found no concrete malicious or supply-chain indicators in the target file: no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, or hidden subprocess execution.",
