q2 i? Across the observation window, no indicators of privilege escalation, inter-user interference, boundary violations, or cross-identity contamination were identified, suggesting the rootless Podman isolation layer maintained effective containment. → Germán Arroyo 2026

q2 · i? · design · r2

Operational security analysis of system-wide API event logs under a single-tenant configuration on the deployed Raspberry Pi platform. The article also reports that "No evidence of cross-identity contamination or simultaneous multi-session identity collision was observed in the dataset," with workload variation attributed to normal user interaction differences.

"Although the system was exposed to continuous network access over an extended period, no indicators of privilege escalation, inter-user interference, or boundary violations were identified. Overall, the results suggest that the rootless Podman isolation layer maintained effective containment of execution environments"
