"""Tests for write-path app_id migration and API key resolution.

Verifies that all scripts writing to the Mem0 API:
1. Pass app_id as a top-level parameter (not in metadata)
2. Do NOT include project_id in metadata
3. Include branch in metadata when available
4. Use resolve_api_key() for key resolution with userConfig fallback
