      "summary": "Reviewed `src/math/libm_math/log2f.rs`, which is a straightforward `f32` base-2 logarithm implementation adapted from FreeBSD/Sun math code. I found no concrete supply-chain indicators in this file: there are no install hooks, subprocess launches, network/exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.",

      "summary": "Reviewed `src/math/libm_math/logf.rs`, which is a standalone `f32` natural-log implementation with numeric constants and branchy edge-case handling for zero, negatives, infinities, and subnormals. I checked for install-time hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators.",
