## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 1.0.3
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The flagged credential and network behavior is attributable to license validation and the package’s own rule service; the telemetry event contains limited product-use fields and has opt-outs. The inspected CLI and license flows do not show unrelated credential collection or exfiltration.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-11-01T03:39:54.199Z

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 identified; the package provides a Swift concurrency lint CLI with license checks and limited product telemetry.

- **Trigger:** Running the CLI; usage telemetry is limited to interactive CLI/MCP sessions, and license requests occur when a license is used or paid functionality is requested.

- **Impact:** No credential theft or unrelated data collection was found in the inspected flows.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-01T03:40:14.256Z

### AI review details

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

- **Mechanism:** It checks license keys with Polar, fetches licensed rule data from Readystack, and may send an event containing the package slug, source, and reason.

- **Rationale:** The flagged credential and network behavior is attributable to license validation and the package’s own rule service; the telemetry event contains limited product-use fields and has opt-outs. The inspected CLI and license flows do not show unrelated credential collection or exfiltration.

- **Files touched:** ~/.config/readystack/swift6-concurrency-lint.json

- **Network endpoints:** api.polar.sh, getreadystack.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest exposes \`cli.js\` as the command entrypoint and declares no lifecycle scripts., The paywall event sends only the event type, package slug, CLI/MCP source, and reason; it skips CI and can be disabled with \`DO\_NOT\_TRACK=1\` or \`READYSTACK\_NO\_TELEMETRY\`., A supplied or stored license key is checked with Polar, the license service; a key is sent to Readystack only to retrieve the package’s rule feed., The downloaded feed is parsed as JSON rules and merged into the linter’s rule list; the engine compiles rule patterns as regular expressions.

- **Evidence against:** The CLI performs network requests for license validation, rule updates, and usage/paywall events., The rule feed is fetched at CLI startup when a license key is available, including a stored key.
