## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 22 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:** 1.5.11
- **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.

Inspected install, bin, dependency, and Claude session-path code shows package-local binary unpacking and a runtime session lookup, not a concrete attack. A clean publication is blocked because nine required citations exceed the eight-citation cap, so the review stays unresolved.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 62.0%

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 confirmed attack was established. The install hook only unpacks vendored platform archives inside the package tools directory, and the indicated Claude config path is a runtime session lookup. A clean verdict cannot be published because the required citation coverage exceeds the citation limit.

- **Trigger:** No attack trigger was confirmed. npm postinstall runs the unpack script, and the Claude path is used when the CLI looks up a session.

- **Impact:** No credential theft, remote payload execution, persistence, or unconsented foreign agent-control write was shown. The remaining issue is an unresolved review constraint, not a demonstrated impact.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-26T11:56:56.902Z

### AI review details

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

- **Mechanism:** The unpack script gunzips named difftastic and ripgrep archives into tools/unpacked. The MCP launcher starts the bundled local bridge. getProjectPath reads a project session path under the Claude config directory.

- **Rationale:** Inspected install, bin, dependency, and Claude session-path code shows package-local binary unpacking and a runtime session lookup, not a concrete attack. A clean publication is blocked because nine required citations exceed the eight-citation cap, so the review stays unresolved.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 62.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** High

- **AI review observations:** package.json postinstall only runs node scripts/unpack-tools.cjs and there is no preinstall or install hook., dependencies do not include the package name thalamus, so there is no runtime self-dependency lifecycle chain., dist/api-BDrqy\_PC.mjs getProjectPath joins CLAUDE\_CONFIG\_DIR or the home .claude projects directory to locate a session file; that read is not an install-time write., scripts/unpack-tools.cjs extracts the platform difftastic and ripgrep archives into the package tools/unpacked directory., bin/thalamus-mcp.mjs respawns the local dist claude MCP stdio bridge with the current Node binary and inherited stdio.

- **Evidence against:** The same behaviors are consistent with a Claude Code client that vendors ripgrep and difftastic and reads local Claude session files when the CLI runs., Marking the package clean would require nine distinct path citations, which exceeds the eight-citation limit, so a clean verdict cannot be finalized from this review.
