## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.4.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The source ties the flagged callback to ARCY’s own widget telemetry, with bounded measurement collection when consent is absent. The manifest has no install hook, and the stage entrypoint uses an offline fetch stub.

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** No malicious attack surface was identified. The fixed POST callback is product telemetry sent to ARCY’s API, and the stage helper substitutes offline responses.

- **Trigger:** An embedded widget observes events and flushes queued batches on a timer or when its batch threshold is reached.

- **Impact:** No package install-time mutation, unrelated credential transfer, or remote code execution was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-24T13:57:21.564Z

### AI review details

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

- **Mechanism:** The client sends event JSON to the telemetry endpoint using its SDK token and omits browser credentials; the stage helper injects a fixture fetch.

- **Rationale:** The source ties the flagged callback to ARCY’s own widget telemetry, with bounded measurement collection when consent is absent. The manifest has no install hook, and the stage entrypoint uses an offline fetch stub.

- **Files touched:** package.json, dist/index.cjs, dist/stage.cjs

- **Network endpoints:** https://api.arcyai.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 95.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json exposes the runtime entrypoints and defines only a prepublishOnly release check and build hook., The runtime POST batches event data to ARCY’s telemetry API using the SDK token and omitting browser credentials., Without consent, collection is limited to an event allowlist and is disabled when Do Not Track or Global Privacy Control is signaled; field descriptions use element metadata rather than entered values., The stage helper injects an offline fetch with fixture responses and a synthetic session token., The declared LiquidJS and Marked dependencies use template and Markdown parser entrypoints; their inspected manifests show build and test scripts.
