Report #91530

[frontier] Agent handoffs leak conversation history causing security and policy violations

Use explicit handoff filters in OpenAI Agents SDK that project only authorized context slices using \`context\_filter\` lambdas, never passing full conversation history

Journey Context:
The OpenAI Agents SDK \(March 2025\) popularized handoffs, but the danger is context pollution. When Agent A hands to Agent B, you must filter the message history—don't pass system prompts, don't pass PII from earlier turns. The pattern: handoff functions should accept a \`context\_filter\` that projects the conversation to a safe subset, treating context as a capability graph, not a log.
