Review Summary

Reviewed src/msgs/deframer/buffers.rs, which is a pure Rust buffer/range management module for TLS deframing: it tracks slices, coalesces/copies buffered bytes, and resizes a read buffer under std. I did not find concrete malicious or supply-chain indicators in this file; there are no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess behavior. I reviewed `src/stream.rs`, which is a TLS stream wrapper that forwards `Read`/`Write`/`BufRead` calls between a `ConnectionCommon` and an underlying transport, plus a few compile-time tests. I did not find any concrete malicious or supply-chain indicators such as install hooks, hidden subprocess execution, credential harvesting, network exfiltration, dynamic code loading, obfuscation, or persistence behavior. Reviewed `src/msgs/message/mod.rs`, which defines TLS message payload enums, parsing/encoding helpers, and message constructors for alerts, handshake, and application data. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file. Reviewed `src/limited_cache.rs`, which implements a bounded in-memory cache with insertion-order eviction and basic get/remove helpers. I checked for install hooks, network or exfiltration, secret access, dynamic code loading, obfuscation, and persistence behavior; none were present in this file.
