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. A managed service can fetch another exact release of this package with npm and execute it. This creates a nested package-release execution path after the service-update feature is enabled. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-19T22:07:45.141Z - **Finished:** 2026-09-19T22:17:20.556Z - **Download time:** 1270 ms - **Static scan time:** 21535 ms - **AI review time:** 552610 ms - **Total time:** 575415 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:** A managed service can fetch another exact release of this package with npm and execute it. This creates a nested package-release execution path after the service-update feature is enabled. - **Trigger:** A server self-update request while the Synaptic Code background service is managed. - **Impact:** A selected registry release can execute in the service context, including any lifecycle behavior of that selected release. - **Evidence paths:** dist/bin.mjs, dist/service-launcher.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-19T22:17:20.556Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Self-installation of an exact package release followed by service execution. - **Rationale:** The package has no install-time hook, so the evidence does not establish automatic malware execution. Its managed self-update path installs and runs another release of the same package, which is a meaningful supply-chain capability requiring a warning. - **Files touched:** runtime/versions/\, runtime/versions/\/node\_modules/@dmccore/code/dist/bin.mjs, runtime/service-state.json - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The runtime updater invokes npm to install an exact, caller-selected release of this same package into a staging directory., The installed runtime is subsequently launched as the service process., Remote updates are gated on a managed background service, but that service enables the self-install path. - **Evidence against:** package.json defines only a bin entry and contains no lifecycle scripts., The update code rejects non-exact versions and runs a preflight before use. ## Affected versions and remediation This report applies to @dmccore/code@0.0.33-synaptic.16. - Review the evidence and your use of @dmccore/code@0.0.33-synaptic.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.
