pub const SELF_ENTITY: &str = "plugmem workspace self";Expand description
The entity a database’s self-description hangs off.
Entity names are normalized (tokenized, joined by spaces), so this is
written the way it is stored — no surprises about what the tokenizer does to
punctuation. It is a reservation: a caller that gives one of its own facts
this exact subject will be mistaken for a self-description, and
Workspace::verify reports the ambiguity rather than guessing.
