Struct NodeCard 

pub struct NodeCard {
    pub node_id: String,
    pub language: String,
    pub text: String,
    pub source_revision: u64,
    pub source_content_hash: String,
    pub source_record_digest: String,
    pub source_body_bytes: u64,
    pub authored_by: String,
    pub authored_at: String,
    pub card_revision: u64,
}

A reader-authored compact view of one node body, in one language.

A card is derived, never canonical. It names the exact body version it was written from — revision and content hash — so a later reader can tell whether it still describes what the store holds, without trusting the prose. Nothing here participates in ranking, path selection or proof; deleting every card changes no answer except the cards themselves.

card_revision is the card’s own compare-and-set token, separate from the node’s revision. Rewriting a card never advances the node.

Fields

node_id: String

language: String

Language tag the card is written in. Part of the identity: a Spanish and an English card for one node coexist and neither shadows the other.

text: String

source_revision: u64

Revision of the node body this card was authored from.

source_content_hash: String

The public token of that body version, kept for provenance. It is not what validity is decided on: it is derived from the event and the node identity, so a write can change the text without changing it.

source_record_digest: String

Digest over the exact stored record of that body version. This is the identity a card is bound to, and the one a reuse check compares.

source_body_bytes: u64

Canonical UTF-8 bytes of the body this card stood in for, recorded at authorship so a reader can see what the card saves without loading it.

authored_by: String

Writer name recorded at authorship.

authored_at: String

RFC3339 instant stamped by the kernel, not by the caller. A historical read compares against this so a card cannot appear before it existed.

card_revision: u64
