      "summary": "Reviewed `src/lib.miri.rs`, a tiny `no_std` Miri bootstrap shim that reexports `compiler_builtins` as `real`. I checked it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed the crate root in `src/lib.rs`, which only defines crate-level feature gates and exposes internal builtin modules for arithmetic, floating-point, memory, target-specific backends, and stack probing. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.",

      "summary": "`src/macros.rs` contains `macro_rules!` expansions for compiler-builtins intrinsics, generating ABI-specific wrappers and symbol aliases for ARM, Apple, PowerPC, mem, and naked-function cases. I checked for install-time execution, network or exfiltration behavior, credential or environment access, dynamic code loading, obfuscation, and persistence hooks, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed `src/math/libm_math/acos.rs`, which is a straight `f64` arccosine implementation using polynomial approximation and `sqrt` for edge cases.

      "summary": "Reviewed `src/math/libm_math/acosf.rs`, which implements a standard `f32` arccosine approximation with range checks and a local `sqrtf` helper. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution; none were present.",
