Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 1.0.4 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The runtime telemetry is limited and opt-out capable, but it is not disclosed in the README. Under the review rules, undisclosed runtime telemetry is suspicious; no credential exfiltration or unrelated collection was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T03:40:01.607Z - **Finished:** 2026-11-01T03:40:38.284Z - **Download time:** 1033 ms - **Static scan time:** 54 ms - **AI review time:** 35589 ms - **Total time:** 36677 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:** Undisclosed runtime telemetry reports anonymous CLI usage and paywall events to the vendor. - **Trigger:** A free CLI run in an interactive terminal, or a missing or rejected license key in an eligible interactive session. - **Impact:** The vendor can count interactive package use and license-check outcomes. No credential or project-data collection was identified. - **Evidence paths:** cli.js, license.js - **Review source:** ai\_review - **Reviewed:** 2026-11-01T03:40:38.284Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI sends small event payloads over HTTPS to getreadystack.com; the code provides opt-outs and excludes CI. - **Rationale:** The runtime telemetry is limited and opt-out capable, but it is not disclosed in the README. Under the review rules, undisclosed runtime telemetry is suspicious; no credential exfiltration or unrelated collection was identified. - **Network endpoints:** getreadystack.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI calls \`pingUse()\` after a free run completes., The usage event sends only event type, package slug, source, and reason to \`getreadystack.com\`., Usage and paywall telemetry are gated to interactive use and can be disabled with \`DO\_NOT\_TRACK=1\` or \`READYSTACK\_NO\_TELEMETRY\`; CI is excluded., The rule feed is fetched only when a license key is present, from the vendor domain, with the key used to retrieve product rules. - **Evidence against:** The README describes the linting and license features but does not disclose the runtime usage telemetry., The telemetry payload does not include credentials, project files, paths, or other environment values. ## Affected versions and remediation This report applies to @readystack/swift6-concurrency-lint@1.0.4. - Review the evidence and your use of @readystack/swift6-concurrency-lint@1.0.4 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. ## Public findings ### 1.
