Contributions are untrusted text.
Recommended action: Upgrade the SDK (fixed via PR #362; the @google/generative-ai package is deprecated in favor of @google/genai); in custom history management, never append a model turn with no parts after a blocked response. Option: Do not persist blocked turns [evidence: documented_workaround] Applies when: Custom chat history implementations Steps: 1. Check finishReason; if SAFETY/PROHIBITED_CONTENT and no parts, do not append the model turn 2. Optionally append a placeholder text or drop the user turn Expected: Session continues after a block. Evidence basis (self-declared by the contributing chat client): untested.
