Struct CeremonyEventRecord 

pub struct CeremonyEventRecord {

    pub event_id: String,
    pub event_type: String,
    pub schema_version: u32,
    pub ceremony_id: String,
    pub definition_name: String,
    pub definition_version: String,
    pub sequence: u64,
    pub occurred_at: String,
    pub actor: Option<CeremonyEventActor>,
    pub correlation_id: String,
    pub causation_id: String,

    pub event_schema_version: u32,
    pub event: Option<Struct>,
    pub previous_record_hash: Vec<u8>,
    pub record_hash: Vec<u8>,
    pub authorization: Option<CeremonyAuthorizationEvidence>,
}

One sealed record of a ceremony’s stream: the fact, its position, and everything that binds it to the records before it.

The fields are the record’s own rather than a rendering of them, so a caller can rebuild the record and verify the chain itself instead of trusting the engine that sent it.

Fields

event_id: String

Occurs once in the stream. Derived from the fact, so one command decided twice cannot land twice.

event_type: String

Catalogue entry this record is an instance of, in snake_case: “step_completed”, “intervention_requested”, and so on.

schema_version: u32

Version of the record’s field set: 3 seals authorization evidence, 2 carries the event without authorization, and 1 has no event payload.

ceremony_id: String

definition_name: String

definition_version: String

sequence: u64

Position in the stream. From one, contiguous, no gaps.

occurred_at: String

RFC 3339.

actor: Option<CeremonyEventActor>

correlation_id: String

The opening record’s id: what ties one session’s records together. Empty when the record names none.

causation_id: String

The record this one was decided against. Empty on the first.

trace_id: String

Empty until a fact carries a trace.

event_schema_version: u32

The shape the payload below was sealed in. Zero on a version-1 record, which has no payload to shape.

event: Option<Struct>

The sealed event, exactly as the digest covers it. Absent on a version-1 record.

A Struct rather than one message per event type: the payload is versioned by event_schema_version and read through the engine’s own upcasters, so freezing its shape in this contract would put the same thing in two places and make every payload change a contract change.

previous_record_hash: Vec<u8>

The previous record’s digest, 32 bytes. Empty on the first record of a stream.

record_hash: Vec<u8>

This record’s digest, over its content and the previous digest. 32 bytes.

authorization: Option<CeremonyAuthorizationEvidence>

Mandatory for schema 3; absent from historical schema 1 and 2. These are the exact authorization fields covered by record_hash.
