The direct late-refresh test complements the real GET tests
`non_inline_two_phase_read_fetches_late_parity_after_two_selected_shards_fail`
and `non_inline_two_phase_read_fetches_late_parity_when_selected_parts_are_missing`,
which verify reader retry and exact body reconstruction. The direct test does
not itself issue a full late GET after changing the metadata identity.
The static LIST keys in `crates/ecstore/tests/fixtures/list_namespace_keys.json`
are also consumed by ODM's `list_through_static_namespace_boundary_matrix`.
The ECStore query replay uses seed `0xec5707`; the ODM matrix retains seed
