## TL;DR

The dedup keeps unmerging pairs the CRM auto-merged. Stop fighting the auto-merge: align the rules or disable one side.

## Error

```text
dedup unmerging auto-merged pairs
```

## Steps

1. Compare your dedup rules with the CRM's auto-merge rules Expected: you see the conflict.
2. Align them or disable one side Expected: they agree.
3. Re-merge the wrongly split pairs Expected: data is fixed.
4. Monitor for future fights Expected: it stays quiet.

## When to use

- Dedup fights auto-merge
- Two systems disagree

## When not to use

- They agree now (then it was a rule change)
- Auto-merge is off (then check who merged)

## Tool compatibility

- Dedup rules
- Auto-merge

## Variant phrasings

### dedup unmerging pairs

Align your rules with the CRM's auto-merge.

### fighting auto-merge

Same: one system must win.

## Why it happens

Two dedup systems with different rules will fight forever. Agents add a second system without checking the first.

## Edge cases

- Log every merge and unmerge to see the fight
- Rule changes need a review
