## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified; reporting is an explicit benchmark feature.

- **Trigger:** A user starts the CLI with --datadog or --snowflake, or configures a reporting interface for a benchmark run.

- **Impact:** Results and associated metadata are uploaded to the reporting destination the user selected or configured.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-03T17:56:06.840Z

### AI review details

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

- **Mechanism:** The selected interface sends benchmark measurements and run or machine metadata to Datadog or the configured Snowflake batch URI.

- **Rationale:** The package’s import entry only exports benchmark functions. Network reporting is enabled through explicit CLI options or interface configuration and uses the corresponding service credentials or configured URI.

### Review decision

- **Verdict:** Clean

- **Confidence:** 96.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package main entry exports benchmark helpers; it does not start a benchmark run on import., The CLI creates Datadog and Snowflake interfaces only when their corresponding options are supplied., The Datadog interface requires an API key, and the Snowflake interface requires a configured gateway URI, topic, and schema ID., The upload interfaces send benchmark measurements and related run metadata to the selected reporting service.

- **Evidence against:** The reporting metadata includes the local username, machine details, and Git revision and branch., The package supports dynamic interface imports, including an interface name supplied through the environment.
