Constants

BUILTIN_SCHEMA_VERSION

Builtin wire schema implemented by the Rust port. Schema v3 adds the @fold$ tree action used by current BNF-family compiler output. Schema v4 adds @key$ lit, the key as a constant rather than read from a token, for grammars that declare their shape instead of delimiting it. Schema v5 adds src to @setval$/@push$, taking a member’s value from the source text the tree builders accumulated.
