Fields

id: EntityId

collection: String

entity: UnifiedEntity

metadata: Option<Metadata>

modified_columns: Vec<String>

persist_metadata: bool

context_index_dirty: bool

replaced_entity: Option<UnifiedEntity>

Prior physical version retained for MVCC history. Present when an UPDATE creates a new physical entity for the same logical row.

replaced_entity_previous_xmax: u64

xmax carried by replaced_entity before this mutation stamped it.

pre_mutation_fields: Vec<(String, Value)>

Snapshot of the row’s named fields BEFORE the mutation was applied. Carried so the post-write secondary-index hook can delete(old) + insert(new) for changed indexed columns. Empty when the entity isn’t a row or the row carried neither a named map nor a schema Arc.
