## TL;DR

The importer silently stopped at 50,000 rows. Check for row limits in the importer, chunk the file, and verify row counts.

## Error

```text
csv import truncated at 50000 rows
```

## Steps

1. Count source vs imported rows Expected: you confirm the truncation.
2. Check the importer for row limits Expected: you find the cap.
3. Chunk the file and import each chunk Expected: all rows land.
4. Assert row counts after every import Expected: it cannot regress.

## When to use

- Import truncated at 50k rows
- A row limit cut it off

## When not to use

- Counts match (then rows failed validation)
- The file has 50k rows (then nothing is wrong)

## Tool compatibility

- CSV imports
- Row limits

## Variant phrasings

### import truncated 50000

Chunk the file and verify row counts.

### csv stopped at 50k rows

Same: a row limit cut it off.

## Why it happens

Limits hide in library defaults. Agents never check because small test files pass.

## Edge cases

- Some limits are per-batch; chunk accordingly
- Log the truncation instead of staying silent
