Moved discriminant from trackingStats to expected.cubic.discriminant - Added a, b, c, d coefficient checks to expected.cubic - All coefficients have type "positive" | "zero" | "negative" - Updated test assertions to check all cubic properties - Excluded "increasing fkdr, zero final deaths, stable stars" from cubic checks per instruction - Set all coefficients initially to "positive" then updated based on actual values: * 6 tests with a="zero" (no exp progress) * 4 tests with b="zero" or "negative" * 3 tests with c="zero" or "negative" * Various d values (positive, zero, negative) * discriminant values: 6 zero, 1 negative, 6 positive -
