"""
T1.6: Action Reads from Key-Value Store

Tests that actions can read configuration values from the datastore.

Test Flow:
1. Create key-value pair via API: {"key": "api_url", "value": "https://api.example.com"}
2. Create action that reads from datastore
3. Execute action with datastore key parameter
4. Verify action retrieves correct value
5. Verify action output includes retrieved value

Success Criteria:
- Action can read from attune.datastore_item table
- Scoped to tenant/user (multi-tenancy)
- Non-existent keys return null (no error)
- Action receives value in expected format
- Encrypted values decrypted before passing to action
