highReviewed `CHANGELOG.md`, which is a plain release history for `rand_core` with version notes and GitHub reference links. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration logic, credential access, dynamic code loading, obfuscation, persistence behavior, or other executable content. `src/block.rs` implements the `Generator` trait and `BlockRng` buffer-management helpers for deterministic RNG cores, including refill, skip, serialization-oriented reconstruction, and byte-filling logic. I checked it for install hooks, subprocess execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload delivery paths, and found no concrete malicious or supply-chain indicators. Reviewed `tests/mod.rs`, which contains ordinary unit tests for `rand_core` RNG traits and adapter behavior (`SeedableRng`, `TryRng`, `TryCryptoRng`, `UnwrapErr`). I checked for install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file. Reviewed `src/lib.rs`, which is a no_std Rust crate root exporting RNG traits (`Rng`, `TryRng`, `CryptoRng`) and deprecated compatibility aliases, plus documentation attributes and blanket impls. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, and hidden subprocess execution; none are present in this file. Reviewed `tests/block.rs`, which is a small unit test module for `rand_core::block` behavior using a deterministic dummy RNG. I checked for install-time hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths; none are present in this file.
