## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. Installation creates a package-owned immutable crouter runtime and applies a narrow version-checked dependency patch; broader setup actions require an explicit user command.

- **Trigger:** npm postinstall; optional explicit crtr sys setup or web serve commands

- **Impact:** No concrete exfiltration, remote payload execution, or foreign AI-agent control-surface mutation established.

- **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/install-runtime.mjs, dist/commands/sys/setup-core.js, dist/clients/web/server.js, dist/core/self-update.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-27T12:44:44.363Z

### AI review details

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

- **Mechanism:** Package-owned runtime bootstrap, local authenticated web UI, and user-invoked setup

- **Rationale:** The install hook performs package-aligned runtime setup and a narrowly targeted dependency patch, while privileged setup and update capabilities are user-invoked. Source inspection found no concrete malicious chain.

- **Files touched:** scripts/postinstall.mjs, scripts/install-runtime.mjs, dist/commands/sys/setup-core.js, dist/clients/web/server.js, dist/core/self-update.js

### Review decision

- **Verdict:** Clean

- **Confidence:** 88.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Medium

- **Evidence for:** package.json invokes scripts/postinstall.mjs on install., scripts/postinstall.mjs patches a pinned pi dependency and installs a crouter runtime under its own runtime home., dist/commands/sys/setup-core.js can install selected companion packages/system tools and save user-provided keys, but only through sys setup.

- **Evidence against:** No credential harvesting or unsolicited exfiltration found., Postinstall has no network API; its runtime install packs the local package and uses npm ci --ignore-scripts., Web server defaults to 127.0.0.1; non-loopback binding requires a supplied token., Source bridge and broker relay are gated by local-origin/token authorization., Self-update is an explicit runtime command, not install-time execution., No unconsented postinstall write to .pi, .claude, Codex, or other broad agent configuration was found.
