When initializing streaming sources in tablet_stream_files_handler we use a reference to the table. We should hold the table while doing so, because otherwise the table may be dropped and destroyed when we yield. Use the table.stream_in_progress() phaser to hold the table while we access it. For sstable file streaming we can release the table after the snapshot is initialized, and the table may be dropped safely because the files are held by the snapshot and we don't access the table anymore. There was a single access to the table for logging but it is replaced by a pre-calculated variable. For logstor segment streaming, currently it doesn't support discarding the segments while they are streamed - when the table is dropped it discard the segments by overwriting and freeing them, so they shouldn't be accessed after that. Therefore, in that case continue to hold the table until streaming is completed. Fixes [SCYLLADB-1533](https://scylladb.atlassian.net/browse/SCYLLADB-1533) It's a pre-existing use-after-free issue in sstable file streaming so should be backported to all releases. It's also made worse with the recent changes of logstor, and affects also non-logstor tables, so the logstor fixes should be in the same release (2026.2).

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
