Overview

An item moves through a small, fixed set of states. The forward path is created (submitted, hash computed, waiting), processing (assigned to a block being built), and committed (its item hash is a Merkle-tree leaf in a finalized block, the normal verifiable resting state; see the sibling term committed). A committed item can be redacted, which withholds its content while every hash and its inclusion proof survive. Deletion is a separate path: deleted_user (user-initiated) and deleted_expired (retention-driven) carry a cancellable grace period, currently 7 days. Deleting the owning account instead hard-deletes its items directly, without a deletion state. The full lifecycle, including who may act at each stage, is in the item lifecycle.
