## TL;DR

The score field's type differs between systems (number vs text), so every sync corrupts it. Align the types, restore the scores, and re-sync.

## Error

```text
lead score corrupted on every sync: field type mismatch
```

## Steps

1. Compare the score field type in both systems Expected: you find the mismatch.
2. Align the types (both numbers, same precision) Expected: they agree.
3. Restore the corrupted scores from history Expected: data is repaired.
4. Re-run the sync and verify scores hold Expected: they are stable.

## When to use

- Lead scores decay on sync
- The field types differ

## When not to use

- Types match (then check the mapping)
- Scores are wrong at the source (then fix the source)

## Tool compatibility

- CRM field type alignment
- Lead scoring sync

## Variant phrasings

### lead score sync corruption

The field types differ between systems. Align them.

### score decayed every sync

Same: type mismatch on the score field.

## Why it happens

One system stores the score as text, the other as a number. Each sync coerces and loses precision.

## Edge cases

- Decimals vs integers: pick one
- Null handling differs by type
