Lints UBL and CII invoice XML against EN 16931 and the national e-invoicing mandates that are live in 2026
AI Security Review
scanned 11d ago · by lpm-firewall-aiSource inspection found no install hook or concrete attack behavior. The flagged network and credential operations are scoped to license validation, the package's rules feed, and guarded interactive telemetry.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user runs the CLI; license and telemetry requests occur only on their respective validation, feed, or interactive usage paths.
Impact
No credential theft, unrelated data disclosure, destructive action, or code execution was established.
Mechanism
The engine checks invoice text locally. License requests go to Polar or the package vendor's rules feed; telemetry sends event metadata under interactive-session and opt-out guards.
AI rationale
Source inspection found no install hook or concrete attack behavior. The flagged network and credential operations are scoped to license validation, the package's rules feed, and guarded interactive telemetry.

Decision evidence
public snapshotAI called this Clean at 96.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes cli.js as the executable and contains no lifecycle script.
- The engine checks supplied text and returns lint findings.
- License keys are sent to Polar for validation; the product rules feed uses the key to retrieve JSON rules from the package vendor.
- The paywall event contains only event metadata and is gated by telemetry opt-outs and an interactive session.
- The separate usage event runs after a free CLI scan and is also gated by telemetry opt-outs and an interactive session.
