Git Merge Base Candidates Sequence

Inputs: [branch refs], [commit graph], [git merge-base --all output], [repository rules]. Review common ancestors of two branches using read-only Git evidence. Preserve every merge-base candidate when criss-cross history produces several; do not choose one arbitrarily or perform a merge. Distinguish graph ancestry from commit date order. Produce a 12-second graph traversal showing both branches converging on the supplied ancestor candidates. Include one concrete verification step that checks the defining task detail against the supplied inputs. Use [audience] and [tone] to calibrate presentation.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
