Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found a postinstall hook, but its package-local behavior is limited to guarded wrapper repair and setup nudges. Agent integration and scheduled workspace setup occur through \`hippo init\`; no concrete attack surface was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T19:26:30.635Z - **Finished:** 2026-10-10T19:27:32.891Z - **Download time:** 2796 ms - **Static scan time:** 3179 ms - **AI review time:** 56277 ms - **Total time:** 62256 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 attack was identified. The install hook delegates to a package-local module that performs guarded wrapper repair and prints setup guidance; agent integration and workspace registration are reached through initialization. - **Trigger:** npm installation runs the postinstall hook; users can separately run \`hippo init\` to configure integrations and workspace maintenance. - **Impact:** No confirmed unauthorized agent configuration change, credential exposure, or malicious persistence was established. The dashboard's inspected entrypoint is described as loopback-only with a per-start token. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T19:27:32.891Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall code checks a skip flag, tries wrapper repair, and prints nudges. Initialization detects existing agent markers and registers project paths in Hippo's workspace registry. - **Rationale:** Source inspection found a postinstall hook, but its package-local behavior is limited to guarded wrapper repair and setup nudges. Agent integration and scheduled workspace setup occur through \`hippo init\`; no concrete attack surface was established. - **Files touched:** package.json, scripts/postinstall.cjs, dist/postinstall.js, dist/cli/init.js, dist/cli/scheduler.js, dist/dashboard/dashboard.js ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook imports a package-local module and exits when the skip flag is set., The postinstall module attempts repair of an existing Codex wrapper and prints setup nudges; it describes first-install integration as opt-in., Agent hook detection is part of the explicit \`hippo init\` flow and checks for existing agent markers., Workspace registration writes a normalized project path to the Hippo registry during initialization., The dashboard is served on loopback with a per-start token. - **Evidence against:** The package defines a postinstall lifecycle hook., Initialization can register workspaces for daily maintenance, creating local persistence when the user runs setup. ## Affected versions and remediation This report applies to hippo-memory@1.71.0. - Review the evidence and your use of hippo-memory@1.71.0 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.
