=================

Thank you so much for wanting to contribute to Guava! Here are a few important
things you should know about contributing:

1.  API changes require discussion, use cases, etc. Code comes later.
2.  Pull requests are great for small fixes for bugs, documentation, etc.
3.  Pull requests are not merged directly into the master branch.
4.  Code contributions require signing a Google CLA.

API changes
-----------

**Transformer**: `HtmlTransformer`, `XmlTransformer`, `FileTransformer`, etc.
**Extractor**: Weight-based selection (tries in descending weight order)

### Key Extractors

`TikaExtractor` (1000+ formats), `PdfExtractor`, `MsWordExtractor`, `MsExcelExtractor`, `MsPowerPointExtractor`, `ZipExtractor`, `HtmlExtractor`, etc.

**Registration**:
```java

        if (lowerEndpoint.contains(".amazonaws.com") || lowerEndpoint.contains("s3.") || lowerEndpoint.contains("s3-")) {
            return StorageType.S3;
        }

        // Default to S3-compatible (MinIO, etc.)
        return StorageType.S3_COMPAT;
    }

    /**
     * Creates a StorageClient based on FessConfig.
     *
     * @param fessConfig the Fess configuration
     * @return configured StorageClient
     */

 *       {@link #threadAssertTrue}, {@link #threadAssertEquals}, or {@link #threadAssertNull}, (not
