What it means
The design is likely to perforate or weaken the substrate through concentrated repeated needle hits.

REPEATED_PENETRATION_RISK
The design is likely to perforate or weaken the substrate through concentrated repeated needle hits.
Material damage riskDeterministic rule
Why it matters
Some materials cannot tolerate dense re-penetration.
Common triggers
- leather
- vinyl
- dense edge retraces
Typical fixes
- reduce density
- increase stitch spacing
- change strategy
Notes
- High-value for leather/vinyl contexts.
