Package coveringleaf holds the schema and queries shared by the two tests that probe a COVERING index leaf from opposite sides — the planner-side shape pin in package embedded_test and the column-metadata pin in package sqldriver_test.

Package explaindiff renders the PHYSICAL plan shape of every query in the yamsql conformance corpus into a stable, diffable text baseline, and diffs two such baselines entry-by-entry.

Package factory is the producer half of the RFC-201 §5 generation factory: generate → execute → bless-or-file → dedup, with cmd/factory-run driving it and pkg/relational/conformance/factorycorpus owning the committed output.

Package factorycorpus is the home of the RFC-201 §5 generation factory's COMMITTED output: machine-generated, oracle-blessed yamsql scenarios that live in the repository as permanent suite content.

Package javacorpus executes the vendored Java `.yamsql` acceptance corpus (parsed by the sibling javayamsql package) against the Go SQL engine.

Package javayamsql parses Apple's `.yamsql` acceptance-test format — the multi-document YAML dialect driving the Java record layer's yaml-tests suite.

Package memoinvariant is RFC-184 W4: a generative memo-invariant harness.

Package plandiff is the Phase 4.-1 plan-equivalence harness from RFC-022 §4.-1.

Package rowdiff is the RFC-182 generative row-soundness differential harness: seeded random (schema, data, query) cases executed through the full production path (sqldriver → Cascades → executor → real FDB), rows diffed against Oracle M — a brute-force in-memory full-scan evaluation over the generator's own authoritative row set, reusing the engine's predicate evaluation (predicates.Comparison.Eval) so the planner is the only component removed.

Package yamsql is a SQL-level conformance harness for the Go SQL driver.
