I verified:

- SHA-512 checksum and signature of the source artifact
- Source matches v4.0.5-rc3 at b472a3aa3c4b71b5a6ff068ef396f757bd662e59
- Apache RAT passed with zero unknown licenses
- Java 17 Hive-enabled source build passed
- VersionUtilsSuite passed (5/5)
- Documentation reports Spark 4.0.5

The signature was verified
using:https://dist.apache.org/repos/dist/dev/spark/KEYS

Please also sync/correct the KEYS link in the vote email, since the
linked downloads.apache.org file does not currently contain this key.
