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. The inspected findings do not establish malicious behavior, but the required clean citation set exceeds the output limit. Manual review is needed to resolve the remaining source coverage. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 70.0% - **Started:** 2026-10-23T05:53:23.672Z - **Finished:** 2026-10-23T05:54:36.133Z - **Download time:** 6947 ms - **Static scan time:** 18128 ms - **AI review time:** 47384 ms - **Total time:** 72461 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 concrete attack surface was confirmed in the inspected source. The update migrator installs package-owned agent hooks, but the inspected excerpts do not establish harmful behavior. - **Trigger:** No malicious trigger was confirmed; the manifest’s postinstall invokes a database repair script. - **Impact:** No attack impact was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-23T05:54:36.133Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected migration code writes agent hook files, while GitSync records active machines’ public signing keys in an allowed-signers file. - **Rationale:** The inspected findings do not establish malicious behavior, but the required clean citation set exceeds the output limit. Manual review is needed to resolve the remaining source coverage. - **Files touched:** package.json, dist/core/PostUpdateMigrator.js, dist/core/GitSync.js, .claude/hooks/free-text-guard.sh ### Review decision - **Verdict:** Manual Review - **Confidence:** 70.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json limits postinstall to a native database repair script and prepare to Husky setup., The update migrator writes package-owned agent hooks, including a guard for credential questions., GitSync writes an allowed-signers file containing active machines’ public signing keys., The inspected hook parses questions and allows requests when none are supplied. - **Evidence against:** The inspected sources do not establish credential collection, exfiltration, or a backdoor., The required clean review would need more citations than the output limit allows. ## Affected versions and remediation This report applies to instar@1.3.1407. - Review the evidence and your use of instar@1.3.1407 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.
