|Note:

| After the last rollback, the "served" branchheads cache became invalid, but
| all changesets in the repo were public. For filtering this means:
|   "immutable" == "served" == ΓΈ.
|
| As the "served" cache is invalid, we fall back to the "immutable" cache. But
| no update is needed between "immutable" and "served" and the "served" cache
| is not updated on disk. The on-disk version therefore stays invalid for some
| time. This explains why the "served" branchheads cache is detected as
| invalid here.
