## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. The sole runtime entrypoint provides local serialization helpers only.

- **Trigger:** A consumer imports index.js and invokes an exported codec helper.

- **Impact:** No external side effects established.

- **Evidence paths:** package.json, index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-12T13:01:13.774Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** In-memory Buffer serialization and decoding.

- **Rationale:** Direct inspection of the manifest and sole entrypoint found no install-time execution or harmful behavior. The package is a small, self-contained BCS codec.

### Review decision

- **Verdict:** Clean

- **Confidence:** 99.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json has no lifecycle hooks or dependencies., index.js only implements local ULEB128 and BCS buffer encoding/decoding., No network, filesystem, subprocess, dynamic-code, or persistence APIs appear in the package files.
