Description

An interrupted TestSeedParsing setup can leave seed_expected behind, causing automatic retries to fail with TABLE_OR_VIEW_ALREADY_EXISTS. Drop that setup table before recreating it, and use the existing rerun-safe fixture to reset the model and seed relations between attempts.

This is a test-only repair. The inherited parsing checks remain unchanged. The initial failure that triggered the reported CI retries is still unknown.

Validation

• Reproduced the leftover-table error on the unmodified base with an injected setup interruption.
• Ran the repaired seed test normally on a Unity Catalog SQL warehouse: 1 passed.
• Injected a setup interruption: 1 passed, 1 rerun in the same schema.
• Injected a failure after the complete test body: 1 passed, 1 rerun; both test executions completed in the same schema.
• All five pre-commit hooks passed.
