+# sqlglotc is the mypyc-compiled companion extension for sqlglot: cibuildwheel
+# builds the `sqlglotc/` subdirectory of the tobymao/sqlglot monorepo, whose
+# setup.py mypyc-compiles a subset of sqlglot's own modules and ships the
+# resulting .so files under the `sqlglot.*` namespace (Requires-Dist pins the
+# matching `sqlglot==<version>`, so importing `sqlglot` picks up the compiled
+# extensions transparently). Upstream publishes wheels for cp310-cp314 (no
+# cp314t - "mypyc doesn't have great support for free threaded builds", same
+# as build-black.yml) on every platform except riscv64; sqlglotc/pyproject.toml
+# carries no [tool.cibuildwheel] table, so CIBW_* here isn't overriding
+# anything upstream committed (mirroring .github/workflows/package-publish.yml's
+# build-wheels job instead). Testing runs upstream's own `make unitc` recipe
+# (SKIP_INTEGRATION=1 python -m unittest) against the installed compiled
+# wheel; duckdb and pandas (imported by tests/test_optimizer.py and
+# tests/test_executor.py) come from our registry since neither ships riscv64
+# wheels on public PyPI.
