OffsetFusionMerge (Union Fusion)

Idea

OffsetFusionMerge keeps all boundaries proposed by any engine.

It is the most permissive fusion strategy.

---

Method

1. Collect union of all boundary positions.
2. Sort them.
3. Convert consecutive boundaries into (start,end) segments.

---

Effect

• High boundary recall.
• Often over-segments.
• Useful when downstream tasks tolerate fine granularity.

---

Recommended for

• Exploratory analysis
• Avoiding missed boundaries
• Post-hoc merging downstream
