## Known open issue

The disk reclaim path has an unclosed race. A store key is
`(entry id, identity)` and identities are reused — the file-id pool hands a
re-opened path its previous record. `reclaim_orphaned_disk` consults the index
before deleting, but a put that has landed while its index record is not yet
installed is invisible to that check, and t4 applies puts and tombstones by
LSN, so the later `remove` wins and deletes live bytes.

Closing it needs a per-write generation in the store key, which also makes
`DiskResidue::superseded` unreachable and removes the in-place-overwrite case.
Not yet done. Do not re-report it as new.
## Reporting a problem

Open an issue. Nothing in this file records a specific bug: a bug is by
definition temporary, and this file goes stale the moment someone fixes one
without remembering to edit it.

Check the open issues before reporting something — known gaps in the cache's
accounting and reclamation are tracked there, and at least one has been
re-discovered more than once.
