Identity resolution is powerful and dangerous in equal measure. Done wrong, you've built a surveillance database. Done right, it just feels like the brand remembers you.

- 04Audit log of every merge event, reversible by support
- 05Match confidence scores so low-confidence merges don't auto-trigger campaigns
