Review Comment:
Thanks for digging that up — confirmed
`HoodieSqlCommonUtils#makePartitionPath` reads hive-style and urlencode from
table config but never `getSlashSeparatedDatePartitioning`, so the DDL commands
compose a dashed path against slash-separated directories.
Agreed it's out of scope here, and I'd rather not widen this PR further.
Leaving it as you suggested, on record next to the tests that create such
tables. Happy to file it separately if you'd like it tracked alongside
#19666/#19668/#19669 rather than living in this thread.
