| Operation | `openWordList(path: Path): tuple[Level, ...]` |
| Traces to | `openWordList` in [SSD-001] |
| Domain Model concepts | Word List, Study Session, Words To Learn ([DM-001]); IT terms `Vocabulary`, `StudySession`, `Deck` ([DICT-001]) |
**Preconditions**
- `path` names an existing file.
**Postconditions**
- The `Vocabulary` of `path` is the word list in use and its progress file (`words_to_learn.csv` for `ms-da.csv`, else `words_to_learn_<name>.csv` in the data folder) is the progress in use.
- Any earlier `StudySession` was dropped and the levels are returned; no card is shown until a level is chosen.
**Exceptions**
| Condition (failing precondition) | Outcome |
| --- | --- |
| The file does not exist or is not a word list (no header of two language codes, a row that is not two cells, or no card) | `VocabularyNotFoundError` or `VocabularyFormatError` is raised; the earlier word list and session stay in use and no file is changed |

| Traces to | `changeLevel` in [SSD-001] |
| Domain Model concepts | Level, Study Session ([DM-001]); IT terms `Level`, `StudySession` ([DICT-001]) |
**Preconditions**
- A word list is in use.
**Postconditions**
- The pending flip timer was cancelled, the `StudySession` was dropped and the levels are returned; the progress file was not changed.

| Operation | `resetWordList(): tuple[Level, ...]` |
| Traces to | `resetWordList` in [SSD-001] |
| Domain Model concepts | Words To Learn, Word List ([DM-001]); IT terms `Deck`, `Vocabulary` ([DICT-001]) |
**Preconditions**
- A word list is in use and the Learner confirmed.
**Postconditions**
- The progress file of the word list in use does not exist; the word list file and the progress files of other word lists are unchanged.
- The `StudySession` was dropped and the levels are returned; the next session starts from a `Deck` of the whole `Vocabulary`.
**Exceptions**
| Condition (failing precondition) | Outcome |
| --- | --- |
| The progress file does not exist | Nothing is deleted and no error is raised |
| The progress file cannot be deleted (`OSError`) | The error is logged and shown to the Learner; the earlier session stays |
## Contract: showContact
| Item | Value |
| --- | --- |
| Operation | `showContact(): tuple[str, str, str]` |
| Traces to | `showContact` in [SSD-001] |
| Domain Model concepts | none (author information, outside the domain) |
**Preconditions**
- None.
**Postconditions**
- The name, the title and the link of the author are returned and the link was opened in the web browser.
**Exceptions**
| Condition (failing precondition) | Outcome |
