evaluator: cross-session memory leakage

[achuvyas-kv]

Area

Agent Evaluators (evaluators/agent/)

Problem or motivation

Agents with persistent memory can leak information from one user session to another, creating privacy and security risks.

Proposed solution

Add evaluator under evaluators/agent/memory-rag/ that:

• Tests if session A's data can be retrieved by session B
• Includes multi-turn patterns for memory probing

Acceptance criteria

• Evaluator YAML file created with pass/fail criteria
• Patterns cover direct and indirect memory retrieval attempts
• Test against customer-support agent (multi-session)
