| 3 | Verifies that every merge strategy (ours, theirs, base, union, manual, auto) |
| 4 | is correctly honoured by CodePlugin.merge() and merge_ops() when a |
| 5 | .museattributes file is present in the repo root. |

| 11 | OURS_ONLY b==r, l!=b only our branch changed it |
| 12 | THEIRS_ONLY b==l, r!=b only their branch changed it |
| 13 | DIVERGENT b!=l, b!=r, l!=r both changed differently |
