## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 13 low-signal pattern(s) reviewed.

- **Verdict:** Manual Review
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Under Review
- **Threat category:** Unknown
- **Selected version:** 4.3.31
- **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy.

The manifest selects an unassessed UMD artifact for CommonJS consumers, and trusted offline analysis could not resolve its behavior. The inspected ES module shows ordinary widget behavior, but that does not establish that the UMD artifact is benign, so manual review is warranted.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

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:** The declared CommonJS entrypoint resolves to an artifact whose executable behavior could not be assessed. No attack is established by the inspected ES module, but it does not resolve the UMD artifact.

- **Trigger:** Importing the package through its CommonJS entrypoint.

- **Impact:** The behavior of the CommonJS entrypoint remains unknown; no concrete impact is confirmed.

- **Evidence paths:** package.json, dist/venue-calendar.umd.js, .lpm-inspection-ZqZ9lW/0-5ba470b5884b.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T23:24:32.688Z

### AI review details

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

- **Mechanism:** The manifest points to the UMD bundle, and trusted offline analysis reports that its format and executable behavior remain unsupported.

- **Rationale:** The manifest selects an unassessed UMD artifact for CommonJS consumers, and trusted offline analysis could not resolve its behavior. The inspected ES module shows ordinary widget behavior, but that does not establish that the UMD artifact is benign, so manual review is warranted.

- **Files touched:** package.json, dist/venue-calendar.umd.js, dist/venue-calendar.es.js

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 90.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest maps the CommonJS entrypoint to the UMD bundle and the module entrypoint to the inspectable ES bundle., Trusted offline analysis could not structurally or executably analyze the UMD artifact, leaving its behavior unresolved., The ES bundle fetches widget configuration and registers the \`micdrop-calendar\` browser element.
