"""P1 Core Tests: Contact Management Flow.
Complete test of contact request/approval workflow.
Test Cases:
1. Request contact from Agent A to Agent B
2. Agent B receives contact request in inbox
3. Agent B approves contact
4. Agent A can now message Agent B
5. Agent B denies contact
6. Denied agent cannot message
7. Contact policy: open (anyone can message)
8. Contact policy: contacts_only (approved only)
9. Contact policy: block_all (nobody)
10. Contact expiration after TTL
11. Cross-project contacts
Verification:
- AgentLink records created with correct status
- Policy enforcement blocks/allows messages
