"""Migration 087 tests — board_program_cycles table.

NOT a real alembic round-trip — the suite builds the test DB via
Base.metadata.create_all (see conftest); a real `alembic upgrade head` +
`downgrade -1` round trip against a scratch Postgres (:55432) was run
manually and confirmed clean (create + drop, no errors) as part of building
this migration. See `alembic/versions/087_board_program_cycles.py`.
