expose

the fourth verb: answer reads over the committed graph. the read path, complement to validate/order/apply (the write path).

expose(query)  → rows | mutation batch     via inf (datalog) over committed state
expose(from,to) → attention                 a focus read, value from tru

cybergraph exposes its relations to inf and forwards focus reads to tru; it does not compute either. see query for the relation schema and attention for the focus read.

mechanism, not decision: expose answers what it is asked. which questions to ask, and what to do with the answers, is the soma control loop — expose is the read primitive that loop calls.

see apply for the write counterpart · query for the interface · inf for the language · tru for focus.
