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. The suspicious static signals resolve to package-aligned setup behavior: postinstall does not install agent hooks, while CLI initialization performs integrations and scheduling. The added sleep-offload code is consistent with server sleep processing, with no concrete attack behavior found in the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-11T11:37:11.817Z - **Finished:** 2026-10-11T11:37:59.531Z - **Download time:** 765 ms - **Static scan time:** 3085 ms - **AI review time:** 43861 ms - **Total time:** 47714 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 identified. The install hook reaches a postinstall path for limited Codex wrapper repair and setup messages; broader agent integrations and scheduling are CLI setup behavior. - **Trigger:** Package installation invokes the manifest postinstall; agent hooks and scheduling are activated by running hippo init or setup. - **Impact:** No malicious behavior was established from the inspected sources; explicit CLI setup can modify agent configuration and create a daily schedule. - **Review source:** ai\_review - **Reviewed:** 2026-10-11T11:37:59.531Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall checks for existing integration state and prints opt-in commands. CLI initialization detects existing agent markers, updates integration files, and may schedule the package's daily runner. - **Rationale:** The suspicious static signals resolve to package-aligned setup behavior: postinstall does not install agent hooks, while CLI initialization performs integrations and scheduling. The added sleep-offload code is consistent with server sleep processing, with no concrete attack behavior found in the inspected source. - **Files touched:** package.json, scripts/postinstall.cjs, dist/postinstall.js, dist/cli/init.js, dist/cli/install-steps.js, dist/server/sleep-offload.js ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest postinstall invokes a small wrapper that imports the optional dist postinstall entry., The postinstall entry only attempts repair of an already-installed Codex wrapper and prints setup nudges; it does not itself install hooks into agent settings., Agent hook detection is based on existing agent marker files, and integration writes are reached through the CLI init flow., Daily scheduling is part of init/setup and can be skipped through an environment setting or CLI flag., The added sleep offload file runs sleep work in a child process with a deadline; it shows no unrelated payload or exfiltration behavior. ## Affected versions and remediation This report applies to hippo-memory@1.72.0. - Review the evidence and your use of hippo-memory@1.72.0 before allowing it.
