Report #102754

[gotcha] Harmful payload split across multiple turns reassembles in context window

Inspect the full conversation context, not just the latest turn, for safety. Use a context-level classifier and maintain a rolling summary rather than naively appending every user message. Detect partial payloads, encoded fragments, and coordinated multi-part patterns across turns.

Journey Context:
Single-turn input filters give a false sense of security. An attacker asks for a benign Python function in turn one, a benign string in turn two, then in turn three asks the model to combine them into malware. Each individual turn passes the filter. Safety must operate on the accumulated context and the assistant's planned action, not isolated utterances.
