3If `multicam_sync` is not loaded yet, load it with `ToolSearch` before calling it, so you use its real parameters instead of guessing.

5Parts 1–3 always run: they produce the synced master, a verifiable fact that every
6later edit is rebuilt from. Part 4 cuts a draft from it by default; skip it only for an explicit sync-only request.
7Transcripts do almost all of the work. AI locates; arithmetic decides frames.

9Use ordinary timelines, tracks, and items only. Never create a compound or nested
10multicam clip, and never depend on a camera-switcher item. If a main edit already
11exists, leave it untouched while building the synced master and speaker-follow
12cutting board on separate timelines.

14## Part 1 — Discover the structure
15 
16Work out what you actually have before aligning anything. Never ask the user how many
17cameras there are. The material already answers it.

19### The two rules that do the work
20 
21**Same words at the same moment → cannot be sequential spans of one camera.** Overlapping
22transcripts mean two devices recorded one event simultaneously, so they are different
23sources or simultaneous angles.
24 
25**No shared words, and one ends where the next begins → one camera that stopped and
26restarted.** These are sequential spans of a single capture source, not separate angles.

28### Steps

301. Read every asset's transcript, build a pairwise overlap matrix — how much text
31   each pair shares, and where — and split by the rules above.
