OffsetFusionIntersect (Strict Consensus)

Idea

OffsetFusionIntersect keeps only boundaries that are proposed by all engines.

This is the most conservative strategy.

---

Method

1. Compute boundary sets per engine.
2. Compute set intersection.
3. Ensure coverage:
   • Add 0 if missing.
   • Add final trace boundary if missing.
4. Convert to segments.

---

Effect

• High precision.
• Low recall.
• Produces coarse segmentation.

---

Recommended for

• When engines are noisy.
• When precision is critical.
