Ignite TC Bot commented on IGNITE-28846:
----------------------------------------
Docs Required triage: I verified the merged change locally in code/ignite
(commit 6e6871673c, PR #13317) and checked the existing snapshot/persistence
docs. The patch fixes dump directory handling for an already-supported
multi-disk/absolute-path storage layout and adds regression coverage; it does
not introduce a new command, API, option, or documented workflow. Removing Docs
Required and leaving Release Notes Required for release-note handling.
