Expand description
Typed parsing for the graph DSL (GRAPH ..., MATCH ...).
A quote-, brace- and bracket-aware tokeniser feeds one parser per
statement. Each parser reads its clauses left to right and produces a
typed [NodedbStatement]. A token that is not a clause of the statement
is a parse error, so a misspelled clause keyword never runs the
statement with a default. Every graph DSL command flows through here
before reaching a handler, so the handlers never touch raw SQL.
Numeric ranges and engine-level caps stay unvalidated here and are
enforced at the pgwire boundary, which keeps this module free of
pgwire dependencies and out of the nodedb → nodedb-sql edge.
Structure is validated here, because the boundary cannot see it: a required clause that is absent, or a clause value outside its own vocabulary, means no statement reaches the boundary at all. Both are reported as a parse error naming what is wrong.
