-- Regression: get_gate_type used to populate the per-process circuit
-- cache with an empty children list, causing the next get_children to
-- silently return zero children. provenance_evaluate (PL/pgSQL) hits
-- exactly that pattern and used to fold custom-semiring plus / times
-- gates over an empty set.

-- The seed table is created by gate_cache_setup in a prior backend; we
-- run in a fresh session here, so the per-process cache starts empty.
