## Security analysis

### Published attack-surface review

- **Summary:** No confirmed attack surface. The entrypoint exports two pure report-processing functions; imported fs/path/os modules are unused.

- **Trigger:** Consumer explicitly calls exported functions.

- **Impact:** No filesystem, network, process, credential, or persistence effect established.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-08T11:05:41.935Z

### AI review details

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

- **Mechanism:** Parse table text and compare gas metrics in memory.

- **Rationale:** Direct inspection found a minimal library with no install hook or harmful runtime behavior. Unused Node built-in imports do not create an attack path.

- **Files touched:** package.json, index.js

### 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 scripts or dependencies., index.js only parses gas-report text and compares numeric values., No network, child-process, eval, persistence, or file-write calls exist.
