Explicit CLI commands can start a local web/control surface and agent integrations; no unconsented foreign AI-agent control-surface mutation was confirmed. - **Trigger:** npm postinstall; later explicit crtr CLI commands - **Impact:** Creates and selects crouter runtime files; runtime commands can manage its own agent workflow. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/install-runtime.mjs, bin/runtime-selector.mjs, dist/core/self-update.js, dist/builtin-pi-packages/pi-crtr-extensions/extensions/provider-rotation.ts - **Review source:** ai\_review - **Reviewed:** 2026-07-27T12:47:34.352Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** package-owned runtime installation and user-invoked agent/web features - **Rationale:** The flagged lifecycle behavior is a package-aligned runtime installer, not a payload chain or foreign control-surface takeover. Inspected sources show explicit user-facing agent/web capabilities but no concrete malicious behavior. - **Files touched:** scripts/postinstall.mjs, scripts/install-runtime.mjs, bin/runtime-selector.mjs, dist/clients/web/web-cmd.js ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** package.json defines postinstall., scripts/postinstall.mjs launches install-runtime.mjs., scripts/install-runtime.mjs runs npm pack/ci and creates a sealed crouter runtime generation. - **Evidence against:** Postinstall only patches/packages this product and uses npm ci --ignore-scripts., No credential harvesting or exfiltration was found in inspected lifecycle code., Companion Pi extensions are advertised for explicit \`crtr sys setup\`, not installed by postinstall., Web command defaults to loopback and requires a token off-loopback., provider-rotation.ts performs provider OAuth rotation, consistent with the agent runtime. ## Public findings ### 1.
