Review rev_7c4226ba21dc43b88dce96d6aa52d2ac

{
  "summary": "Reviewed the ARM assembly implementation of `curve25519_x25519base_alt`, which performs X25519 base-point scalar multiplication and an inline modular inverse using only local arithmetic, constant-time table selection, and stack-resident temporaries. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
