Review Summary

`src/lib.rs` is a small Adler-32 checksum implementation with optional `std`-only buffered I/O support and tests. I checked it for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file. Reviewed `README.md`, which is a normal crate overview for an Adler-32 checksum library with dependency usage, MSRV, and performance notes. I checked for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file. Reviewed the `Cargo.toml.orig` manifest for install-time hooks, hidden subprocesses, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior. The file only defines package metadata, a benchmark target, feature flags, and release automation metadata; I found no concrete malicious or supply-chain indicators and no install hooks, network activity, credential harvesting, or payload-loading logic in this target file. I reviewed `benches/bench.rs`, which is a Criterion benchmark harness for `adler2` checksum routines over fixed in-memory buffers. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file. Reviewed this manifest for install-time execution, hidden subprocesses, credential or secret access, network/exfiltration, dynamic code loading, obfuscation, and persistence tampering. It appears to be a normal `adler2` library manifest for an Adler-32 checksum crate, with no build scripts, no install hooks, and no suspicious dependency or metadata behavior in this file.
