## Security analysis

### Published attack-surface review

- **Summary:** Install-time behavior creates a package-owned immutable runtime under ~/.crouter/runtime and patches a precisely pinned direct dependency. Runtime networking observed is localhost/Unix-socket service behavior; issue submission requires an explicit feedback command.

- **Trigger:** npm postinstall; explicit crtr sys feedback or runtime web-server commands

- **Impact:** No confirmed malicious attack surface or unconsented broad AI-agent control-surface mutation.

- **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/install-runtime.mjs, scripts/patch-pi-tree-root-ordering.mjs, bin/runtime-selector.mjs, dist/clients/web/server.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-29T17:26:56.646Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** package-owned runtime bootstrap, pinned dependency compatibility patch, and local agent service

- **Rationale:** The lifecycle behavior is substantial but source-aligned: it builds and integrity-checks a package-owned runtime and applies a narrow version-pinned compatibility patch. No concrete malicious chain, secret theft, exfiltration, or foreign/broad agent-control mutation was identified.

- **Files touched:** scripts/postinstall.mjs, scripts/install-runtime.mjs, scripts/patch-pi-tree-root-ordering.mjs, bin/runtime-selector.mjs, ~/.crouter/runtime, ~/.crouter/feedback, node\_modules/@earendil-works/pi-coding-agent/dist/modes/interactive/components/tree-selector.js

- **Network endpoints:** https://github.com/crouton-labs/crouter/issues, http://127.0.0.1

### Review decision

- **Verdict:** Clean

- **Confidence:** 90.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for:** postinstall runs scripts/postinstall.mjs., Postinstall patches one pinned pi dependency file and installs a runtime under ~/.crouter/runtime.

- **Evidence against:** scripts/postinstall.mjs skips runtime installation in CI and treats failures as non-fatal., scripts/install-runtime.mjs packages this package, uses npm ci --ignore-scripts, and validates/seals the generated runtime., bin/runtime-selector.mjs dynamically imports only a validated entry inside the selected runtime generation., Feedback network action is only the explicit crtr sys feedback command via gh., dist/clients/web/server.js serves a local HTTP endpoint and proxies to a local Unix socket., No credential harvesting, covert exfiltration, foreign agent-config mutation, or remote payload download was found.
