Conceptual model · 1 min read

Parsing safety and action authority

Editorial conceptual model derived from the linked cases and official guidance; not a vendor architecture diagram or an exploitation sequence.

The conceptual model

Untrusted input is parsed with memory safety and limited privileges. A bounded typed result still requires an independent meaning and authorization check before any scoped operation; failed checks reject the request.
