# an adapter that had to move whenever the engine did would force a release for
# changes that do not touch it.

# M2: the real adapter. `datafusion` and `ddx-core` must resolve the SAME
# `sqlparser` version or Path B's bridge won't compile — the workspace
# Cargo.toml documents the pin and tests/sqlparser_pin.rs enforces it in CI.
#
# `ddx-ad` is deliberately NOT a dependency yet: it's still an empty v2 scaffold
# (M3/M4), and depending on it now would buy nothing.
