Scope Isolation Test Plan (plugin-v2)

Goal

Prove strict separation for:

• session memory (run_id)
• long-term memory (user_id)
• merged all

Cases

1. Write session marker only, verify:
   • found in scope=session
   • not found in scope=long-term
2. Write long-term marker only, verify:
   • found in scope=long-term
   • not found in scope=session
3. Write one marker in each lane, verify:
   • both appear in scope=all
   • dedupe stable when identical text appears in both lanes

Pass Criteria

• zero cross-lane leakage for cases 1 and 2
• deterministic merged output in case 3
