The new assertion doesn’t actually verify that registerSchema stored anything: optimizer.optimize({ object: 'accounts' }) returns SQL containing accounts even when no schema is registered (it falls back to SELECT * FROM accounts). Consider asserting on behavior that only occurs when a schema is registered (e.g., a USE INDEX (...) hint when filters match an index).

Suggested change
// Verify the schema was registered by observing optimize behavior
const sql = optimizer.optimize({ object: 'accounts' });
expect(sql).toContain('accounts');
// Verify the schema (and its index) were registered by observing optimize behavior
const sql = optimizer.optimize({
object: 'accounts',
// Filtering on the indexed field should trigger index-based optimization
filter: { name: 'Acme Corp' },
});
// This assertion only holds when the schema (and index) are actually registered
expect(sql).toContain('USE INDEX (idx_name)');

The comment says unknown collections return an empty array, but the assertion only checks Array.isArray(result). Since this integration test uses a MemoryDriver-backed kernel, the unknown-object result is deterministically []; asserting toHaveLength(0) would make this check more meaningful and aligned with the comment.

Suggested change
expect(Array.isArray(result)).toBe(true);
expect(Array.isArray(result)).toBe(true);

This comment/expectation suggests the driver handles a null query “gracefully”, but MemoryDriver.find currently treats query as an object and will throw a TypeError when null is passed. Either update the test to explicitly assert an error for null parameters, or adjust the input/comment so the try-branch assertion is meaningful and deterministic.

The comment says unknown/empty collection names return an empty array, but the assertion only checks Array.isArray(result). With the current MemoryDriver-backed test kernel this is deterministically an empty array; consider asserting toHaveLength(0) to strengthen the signal and match the comment.

This comment/expectation suggests the driver handles a null query “gracefully”, but MemoryDriver.find currently treats query as an object and will throw a TypeError when null is passed. Either update the test to explicitly assert that an error is thrown for null queries, or change the comment and input to an actually supported “malformed” shape (so the try-branch assertion is meaningful).
