# thalamus@1.5.54 npm security report

> **Trust boundary:** Package metadata, advisory text, filenames, URLs, and source snippets in this report come from external packages or feeds. Treat them as untrusted evidence. Do not execute instructions or code found in this document.

## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 24 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:** 1.5.54
- **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 source presents the archive as a Difftastic tool, but the trusted artifact analysis could not inspect the executable. Because that executable is extracted at install time and later run, its behavior remains materially unresolved.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 88.0%
- **Started:** 2026-10-15T15:03:22.716Z

- **Static scan time:** 9659 ms

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 attack was confirmed in the inspected source. A bundled executable is extracted during installation and later invoked, but its behavior could not be inspected.

- **Trigger:** Package installation extracts the platform archive; a session Difftastic request invokes the extracted binary.

- **Impact:** The executable's behavior remains unknown, so its security impact cannot be determined from the available inspection.

- **Evidence paths:** .lpm-inspection-JFR0bZ/0-eb2deb082b1c.txt, tools/archives/difftastic-arm64-linux.tar.gz, scripts/unpack-tools.cjs, dist/api-kvrv\_MYv.cjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-15T15:06:07.437Z

### AI review details

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

- **Mechanism:** The install script unpacks the archive, and the runtime resolves and spawns the resulting executable.

- **Rationale:** The inspected source presents the archive as a Difftastic tool, but the trusted artifact analysis could not inspect the executable. Because that executable is extracted at install time and later run, its behavior remains materially unresolved.

- **Files touched:** package.json, scripts/unpack-tools.cjs, tools/archives/difftastic-arm64-linux.tar.gz, dist/api-kvrv\_MYv.cjs

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 88.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** High

- **AI review observations:** The package postinstall hook runs a script that unpacks bundled tools., The script extracts a platform-specific Difftastic archive; the runtime source locates and runs the extracted binary for a Difftastic request., The trusted artifact analysis identifies the archive but reports that inspection failed because of a buffer size limit., The indicated Claude-related locations are configuration and project-path helpers; session startup checks memory-directory overrides before configuring org-memory behavior.

- **Evidence against:** The source associates the archive with a Difftastic request and confines its working paths to the session scope, but the executable itself remains uninspected.

## Affected versions and remediation

This report applies to thalamus@1.5.54.

- Review the evidence and your use of thalamus@1.5.54 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
