+### Please describe the problem.
+
+In a secondary worktree on Windows, pointer files remain even with keys being available.
+A git annex get fails with "not available", even though "whereis" reports "[here]".
+
+I would expect the behavior to be internally consistent (keys being available in the
+worktree when they are found to be available in the repository).
+
+This report assumes that secondary worktrees are, in principle, a supported use case,
+based on the statement at https://git-annex.branchable.com/tips/Using_git-worktree_with_annex/:
+"Getting, dropping and syncing content works fine in a worktree".
+
+### What steps will reproduce the problem?
