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 manifest confirms an automatic postinstall hook that deletes package-local React and ReactDOM directories, while also declaring them as peer dependencies. This presents unresolved install-time dependency disruption risk, but the inspected source does not establish broader destructive behavior or a publish-blocking attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-16T01:43:43.874Z - **Finished:** 2026-10-16T01:44:43.414Z - **Download time:** 1293 ms - **Static scan time:** 460 ms - **AI review time:** 57787 ms - **Total time:** 59540 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:** The postinstall hook removes React and ReactDOM directories from the package’s node\_modules directory. This creates a risk of disrupting dependency resolution when nested peer copies are present. - **Trigger:** Installing the package runs its postinstall hook. - **Impact:** Nested peer dependencies may be removed and dependent code may fail to resolve them. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-16T01:44:43.414Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook recursively deletes the package-local React and ReactDOM directories, ignoring errors. - **Rationale:** The manifest confirms an automatic postinstall hook that deletes package-local React and ReactDOM directories, while also declaring them as peer dependencies. This presents unresolved install-time dependency disruption risk, but the inspected source does not establish broader destructive behavior or a publish-blocking attack. - **Files touched:** node\_modules/react, node\_modules/react-dom ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook removes React and ReactDOM directories from the package’s node\_modules directory., The package declares React and ReactDOM as peer dependencies, so removing nested copies may disrupt dependency resolution. ## Affected versions and remediation This report applies to @1interface/chat-core@0.20.2. - Review the evidence and your use of @1interface/chat-core@0.20.2 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.
