Review rev_f26a8fc7b6ac4f098c0a5013383cd19e

{
  "summary": "Reviewed the ARM assembly in `bignum_tomont_p384.S`, which is a straight-line P-384 Montgomery-form conversion routine with fixed loads, arithmetic reduction steps, and stores back to the caller-provided buffer. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed the x86-64 assembly implementation of `bignum_sqr_4_8_alt`, which performs a fixed big-number squaring routine with ABI shims and stack-protection metadata only. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed this test file, which defines static ARM `/proc/cpuinfo` fixtures and asserts `crypto_get_arm_hwcap2_from_cpuinfo()` returns the expected flags. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain behavior in this target file.\nReviewed `aws-lc/crypto/fipsmodule/ml_dsa/mldsa/reduce.h`, which contains inline Montgomery/reduction helpers and constant-time conditional addition for ML-DSA field arithmetic. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed `aws-lc/crypto/fipsmodule/rsa/blinding.c`, which implements RSA blinding parameter generation, update, convert, and invert helpers using OpenSSL/AWS-LC bignum primitives. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
