Change one fact at a time
This fictional conversation starts with a user requesting Tuesday at 15:00 for two people. Corrections update only the stated field. The assistant is preparing a request summary; it has no booking authority in this fixture.
| Current state | Correction | Expected summary |
|---|---|---|
| Tuesday 15:00; two people | 「改星期三，時間照舊。」 | Wednesday 15:00; two people; not booked |
| Wednesday 15:00; two people | Make that three people; keep Wednesday. | Wednesday 15:00; three people; not booked |
| Wednesday 15:00; three people | 「唔係三點，係四點。」 | Wednesday 16:00; three people; not booked |
Review meaning before fluency
| Check | Pass condition |
|---|---|
| Changed fact | Latest explicit correction replaces the earlier value |
| Unchanged facts | The date/time/headcount not being corrected remain intact |
| Action status | The summary does not claim a confirmed booking |
Add separate English and zh-HK versions of each turn using natural wording rather than word-for-word translation. Record factual retention and language quality separately. A fluent response can still lose a correction; these examples provide expected states without any actual model run.
