Items
item lifecycle, ownership vs authorship, the composite fingerprint.
Item Lifecycle
The states a Truestamp item moves through from created to committed, plus the terminal redacted and deletion states, what each means to a user, how an item advances to committed, and how ownership governs who can act at each stage.
Item Ownership vs Authorship
The Item split between immutable authorship (audit-only creator record excluded from every hash, with one exception when the author's account is deleted) and transferable ownership (the user or team rights holder driving all rights-based decisions), plus the creator-retains vs team-retains model.
Item Visibility
The three item visibility levels (private, team, public), who can read an item at each level, how public items are discovered through anonymous search and the public verification page, who can set and change visibility, and why visibility changes never affect an item's hashes or proof.
Submit an Item
How to timestamp data by submitting an item on the web form, JSON:API, GraphQL, console WebSocket, CLI, or an MCP agent, with every claims field (name, hash and hash type, description, URL, location, timestamp, metadata), hash mode versus plan-gated claims-only mode, and the limits that apply.
The Item's Composite Fingerprint
How an item's claims fingerprint and timing fingerprint are bound into the composite fingerprint (item_hash) so user data stays independently verifiable, the witnesses that open the submitted-after edge are committed, and authorship is deliberately excluded from every hash.
