## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 25 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:** 1.3.1418
- **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 inspected excerpts did not verify the scanner’s credential-redirection claim or another concrete attack. A clean verdict requires citations for more distinct source paths than the output permits, so the remaining source coverage is unresolved.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 57.0%

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 concrete attack was established in the inspected source excerpts. The postinstall behavior inspected is a native-module repair path, while the credential-redirection claim remains unresolved.

- **Trigger:** Package installation triggers the postinstall repair script; Telegram requests occur during adapter use.

- **Impact:** No attack impact was confirmed from the inspected excerpts; unresolved source coverage prevents a clean determination.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-24T12:50:09.821Z

### AI review details

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

- **Mechanism:** The repair script retrieves a matching native prebuild from the better-sqlite3 GitHub releases or falls back to a source build. The inspected Telegram request targets Telegram’s Bot API with the configured token.

- **Rationale:** The inspected excerpts did not verify the scanner’s credential-redirection claim or another concrete attack. A clean verdict requires citations for more distinct source paths than the output permits, so the remaining source coverage is unresolved.

- **Files touched:** package.json, scripts/fix-better-sqlite3.cjs, dist/messaging/TelegramAdapter.js

- **Network endpoints:** https://github.com/WiseLibs/better-sqlite3/releases/download/, https://api.telegram.org

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 57.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The package install hook invokes a native-module repair script that attempts a better-sqlite3 prebuild from the project’s GitHub release and can fall back to a source build., The inspected Telegram adapter constructs requests for api.telegram.org using the configured bot token; no unrelated credential recipient was confirmed in that excerpt., The source review did not cover the full set of files needed to support a clean verdict, and that citation set exceeds the output limit.

- **Evidence against:** The inspected excerpts do not establish credential redirection, persistence backdoors, or another concrete attack.

## Affected versions and remediation
