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. No confirmed attack surface was established from the inspected source. Required clean citation coverage cannot fit the output limit. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-30T20:09:25.061Z - **Finished:** 2026-09-30T20:14:03.138Z - **Download time:** 4392 ms - **Static scan time:** 20266 ms - **AI review time:** 253418 ms - **Total time:** 278077 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:** No confirmed attack surface was established from the inspected source. Required clean citation coverage cannot fit the output limit. - **Trigger:** Installation invokes runtime dependency setup; explicit CLI commands activate gateway operations. - **Impact:** No malicious impact was established; the citation constraint prevents a compliant clean determination. - **Review source:** ai\_review - **Reviewed:** 2026-09-30T20:14:03.138Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Inspected installation code installs package runtime dependencies, and the terminal caller preserves localhost authentication requests; no concrete malicious mechanism was established. - **Rationale:** Static inspection did not establish independently supported behavior warranting a warning or block. Manual review is required because mandatory clean coverage needs 15 distinct path citations while the schema permits only eight. ### Review decision - **Verdict:** Manual Review - **Confidence:** 99.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** High - **AI review observations:** package.json activates hooks/postinstall.js during installation., The postinstall hook invokes SQLite runtime setup; the inspected installer requests better-sqlite3 rather than another polyrouter release., The terminal API client caller changes only the port, preserving its localhost destination., Required clean coverage names 15 distinct paths, exceeding the eight-citation limit. ## Affected versions and remediation This report applies to polyrouter@1.0.16. - Review the evidence and your use of polyrouter@1.0.16 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.
