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. On npm install for macOS arm64, a pre-existing ~/.gmax vendor directory causes replacement of @lancedb/lancedb's JavaScript distribution and native binary. This is an automatic, unverified native-code overlay; no confirmed exfiltration or AI-agent mutation occurs at install time. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-08-26T03:39:26.054Z - **Finished:** 2026-08-26T03:40:24.986Z - **Download time:** 509 ms - **Static scan time:** 5497 ms - **AI review time:** 52924 ms - **Total time:** 58932 ms The recorded confidence comes from the underlying analysis.

This is an automatic, unverified native-code overlay; no confirmed exfiltration or AI-agent mutation occurs at install time. - **Trigger:** npm install on darwin-arm64 with ~/.gmax/vendor/lancedb-0.38.0-beta.10 present - **Impact:** A locally supplied native binary becomes the dependency implementation used by grepmax. - **Evidence paths:** package.json, scripts/postinstall.js, dist/commands/codex.js, dist/commands/plugin.js, dist/lib/workers/download-worker.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T03:40:24.986Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies unverified vendored native dependency files - **Rationale:** The automatic unverified native dependency overlay is a real install-hook risk that warrants a warning. The flagged Codex configuration behavior is explicit-command-only, and no concrete exfiltration or malicious control-surface mutation was found. - **Files touched:** ~/.gmax/vendor/lancedb-0.38.0-beta.10/dist, ~/.gmax/vendor/lancedb-0.38.0-beta.10/lancedb.darwin-arm64.node, @lancedb/lancedb/dist, @lancedb/lancedb/.gmax-vendored ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Install hook replaces a dependency's dist directory and native binary from ~/.gmax/vendor without integrity verification., The replacement runs automatically on darwin-arm64 when the vendor files exist. - **Evidence against:** Postinstall does not modify AI-agent configuration., Codex MCP registration and AGENTS.md writes are reached only through explicit gmax plugin commands., Observed network download is model-file retrieval from Hugging Face; local service calls target 127.0.0.1., No credential harvesting or exfiltration found in inspected source. ## Affected versions and remediation This report applies to grepmax@0.26.23. - Review the evidence and your use of grepmax@0.26.23 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.
