AutoSync build based on official Nuvio 0.4.26-beta.
What changed
- Added a conservative grouped-reply timing refinement for confident drift-corrected matches.
- Targets 2:2 dialogue groups where the second subtitle starts too early but ends at the correct speech boundary.
- Can move only the second cue start while preserving its end.
- Requires a real reference gap, bounded correction, valid cue duration and supporting simple groups on both sides.
- Ambiguous/overlapping reference gaps and estimated reference ends are ignored.
- This is output-only: it does not change candidate scoring, confidence or reference selection.
Designed to improve chained dialogue without affecting ordinary one-line matches.
