pub const ENTITY_LABEL: &str = "Entity";Expand description
Label/prop name constants for the two built-in write shapes
(create_memory/create-memory, create_entity/create-entity). Single
source of truth shared by every front end (topodb-mcp’s default
IndexSpec and write tools, topodb-cli’s
create-entity/create-memory subcommands) so writes land on exactly the
(label, prop) pairs the default spec indexes — search and lookup work
out of the box regardless of which front end wrote the data.
