Deletion strategy scales in complexity with system distribution: single-node systems use soft delete to preserve structural invariants (sequence contiguity, trie connectivity), distributed systems additionally require tombstones and delete markers for anti-entropy, and the KV store demonstrates both layers coexisting in a single system.
Soft delete for structure preservation and tombstones for distributed convergence are complementary layers that compose
