**Purpose**: Verify proper resource management in Extractor implementations.

**Key Test Areas**:
- Resource closure on successful extraction (MS Office extractors)
- Resource closure on failed extraction
- Improved error messages with context
- Input validation using `validateInputStream()`

**Covered Extractors**:
- MsWordExtractor
- MsExcelExtractor
- MsPowerPointExtractor
- TextExtractor

**Test Count**: 8 tests

## Status

ACCEPTED

## Consequences

### Positive Consequences

* **Improved consistency**: The codebase has a uniform language standard
* **Easier onboarding**: New contributors have clear guidance on which spelling to use
* **Better searchability**: Finding code and documentation becomes more predictable

### Generate a TypeScript Client with Custom Operation IDs { #generate-a-typescript-client-with-custom-operation-ids }

Now, if you generate the client again, you will see that it has the improved method names:

As you see, the method names now have the tag and then the function name, now they don't include information from the URL path and the HTTP operation.
