| 1 | # Empty final formatting run |

| 3 | `input` is the 24-byte minimized stateful fuzz input retained from the M7 text |
| 4 | editing campaign. The old oracle represented only characters and lost the |
| 5 | insertion style of an emptied final run. An insertion there inherited the |
| 6 | retained final run's style, which disagreed with that incomplete oracle. |
| 7 | |
| 8 | The stable semantic replay is |
| 9 | `tests/edit.rs::an_emptied_final_run_retains_its_insertion_style`: erase UTF-16 |
| 10 | positions 22..27 in the native formatted fixture, insert `a` at 22, and require |
| 11 | the original final run's formatting. The current fuzz oracle carries an explicit |
| 12 | terminal style marker. Fixture-selection bytes have changed as cases were added; |
| 13 | the named regression is the replay independent of that encoding. |
