35,000

## Final size

100,000 rows

Hard maximum:

100,000 rows

## FABLE.5 preservation

FABLE.5 messages and tool-call information are retained.

The preprocessing adds an explicit `[FABLE5_TRACE]`
marker for provenance.

## Processing

- streaming dataset loading
- CPU-only processing
- quality filtering
- exact deduplication
- code detection
- debugging detection
- reasoning detection
- web-development detection
- agent/tool-use detection
- source provenance
- FABLE.5 minimum enforcement
- hard 100K row limit
