Git Merge Base Candidates Narration

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 45-second engineering handoff naming the candidate count and uncertainty. Include one concrete verification step that checks the defining task detail against the supplied inputs. Use [audience] and [tone] to calibrate presentation.

Use only the supplied facts and approved wording. If a necessary script or timing reference is missing, ask for it first. Produce the audio when supported; otherwise return the complete spoken script with pauses and a short production cue sheet, clearly labeled as a script. Use original voices and keep speech intelligible without music. Never claim an audio file exists unless it was generated.
