⚠ Under review

Shared build configuration for TypeScript projects — ESLint, Prettier, tsconfig, and Playwright presets

AI Security Review

scanned 9d ago · by lpm-firewall-ai

The inspected lifecycle and runtime source did not establish an attack, and the poster is not selected by the postinstall asset-copy list. Its structure remains unresolved, so this review cannot classify the package as clean.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

The package postinstall runs on installation; no activation path for the poster was found.

Impact

No attack impact is established; the unresolved poster prevents a clean decision.

Mechanism

The poster is packaged as an asset, while the postinstall source selects only two logos for copying. Its remaining behavior is unresolved because its structure could not be analyzed.

AI rationale

.lpm-inspection-ZVCpQE/0-163ed93a16b3.txtassets/image/jews-support-a-free-palestine-poster.pdfsrc/postinstall.jspackage.json

Decision evidence

public snapshot

AI called this Manual Review at 87.0% confidence as Unknown with medium false-positive risk.

AI review observations

The package includes assets/image and runs src/postinstall.js during installation.
The postinstall asset list names only two logos; it does not select the poster.
The trusted offline analysis could not identify the poster’s format beyond an unrecognized artifact and reports no supported structural or executable analysis.

Evidence against

No inspected source path loads or executes the poster; the postinstall asset list copies only the two named logos.
