Graph edges between records — SurrealDB's RELATE — with the same honest write outcomes as DrinkMeAlice.Tx.

Edge tables are TYPE RELATION tables (DDL via DrinkMeAlice.Ash.Schema.edge_statements/4, or by hand). A node is {table, key} where key is a string or integer record key.

{:committed, _} = Graph.relate(conn, "blocks", {"task", "a"}, {"task", "b"}, %{"why" => "needs api"})
{:ok, ["b"]}    = Graph.outgoing(conn, {"task", "a"}, "blocks", "task")

Table and edge names must be identifiers (DrinkMeAlice.identifier?/1); keys and field values travel as bound params. String keys and top-level string field values travel exact (DrinkMeAlice.exact_string/1 — 3.0.5 coerces date-, UUID- and record-shaped strings); nested field values are canonical terms and are NOT protected from that coercion. Field names must be identifiers.
