hmos-multidevice-scenario-entry

This module is a remote installer that fetches untrusted artifacts, extracts them, and deploys them into platform directories. While it does not show overt backdoor/exfiltration behavior, it has substantial supply-chain and host-safety risks: unauthenticated downloads (no integrity/signature), potentially unsafe zip extraction via unzip without explicit traversal protections, and destructive rm -rf operations on cache and target paths derived from user-controlled inputs. A compromised upstream artifact or crafted inputs could lead to file clobbering or installation of malicious/unexpected content into local environments.

SUSPICIOUS: the skill's routing purpose is coherent, but it extends trust by auto-installing additional scene skills through an unseen remote_load.sh path. The main issue is unverifiable transitive skill loading, not confirmed malicious behavior in the shown file.
