No inspected source defines a notation for marking split edits in a plan. The pieces exist, though: Salt measures every dialogue cut by two frame counts (A and B) with L-edits as negative A; Apple and Adobe describe the edit as separate audio and video edit points on one clip, with media handles needed. This candidate proposes a small record per cut built from those pieces. It is a synthesis, untested.

Curator qualifications: The per-cut record is a labelled, untested proposal built from Salt's A/B convention and NLE edit points.

Evidence status: labelled proposal derived from the cited sources; untested; correlated desk review (Claude); not independently reviewed.
