Installation creates an immutable crouter-owned runtime under its own home and patches its bundled pinned dependency; remote actions are explicit CLI features. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 86.0% - **Started:** 2026-07-28T22:08:39.720Z - **Finished:** 2026-07-28T22:09:22.658Z - **Download time:** 1528 ms - **Static scan time:** 4132 ms - **AI review time:** 37277 ms - **Total time:** 42938 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. Installation creates an immutable crouter-owned runtime under its own home and patches its bundled pinned dependency; remote actions are explicit CLI features. - **Trigger:** npm postinstall or explicit crouter CLI commands - **Impact:** No credential harvesting, covert exfiltration, remote payload loading, or broad foreign agent-control mutation was confirmed. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/install-runtime.mjs, scripts/patch-pi-tree-root-ordering.mjs, bin/runtime-selector.mjs, dist/commands/pkg/cli-manage.js - **Review source:** ai\_review - **Reviewed:** 2026-07-28T22:09:22.658Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** package-owned runtime installation and user-invoked agent/CLI operations - **Rationale:** The install hook performs package-aligned runtime setup rather than a concrete malicious chain. Dynamic loading and network use are guarded local-runtime or explicit user-command behavior. - **Files touched:** scripts/postinstall.mjs, scripts/install-runtime.mjs, scripts/patch-pi-tree-root-ordering.mjs, bin/runtime-selector.mjs, dist/commands/pkg/cli-manage.js ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** \`scripts/postinstall.mjs\` runs at install and creates a package-owned runtime., \`scripts/patch-pi-tree-root-ordering.mjs\` modifies a pinned dependency inside crouter's dependency tree. - **Evidence against:** \`package.json\` has no preinstall hook; postinstall only invokes bundled runtime setup., \`scripts/install-runtime.mjs\` packages this project, installs dependencies with \`--ignore-scripts\`, validates and seals its runtime., \`bin/runtime-selector.mjs\` dynamically imports only a validated local runtime generation., GitHub issue filing in \`bin/runtime-selector.mjs\` requires explicit \`crtr sys feedback\` use., \`dist/commands/pkg/cli-manage.js\` fetches endpoints only after explicit registration and keeps credentials in environment variables. ## Public findings ### 1.
