This is a curated English edition of a legacy Portuguese article originally published on 2025-05-11. It preserves the public argument and editorial intent while avoiding private details, operational state, or unsupported new claims.
Core idea
The original article uses public prompt-leak episodes to discuss how model instructions can be exposed, contested, or misunderstood by users.
Its lasting point is architectural: prompts are not a security boundary by themselves. Sensitive behavior needs layered controls, narrow permissions, reviewable logs, and fail-closed design.
Editorial note
This translation was prepared during the governed migration of the legacy blog into the GitHub Pages hub. Technical references may age; when the topic involves law, public policy, infrastructure, or model behavior, treat the article as educational context and verify current sources before acting.
