• Stable core — 84 centers active all 12 trailing months, projected forward on their real seasonal shape (Dec peak ≈ 1.11×, Jun trough ≈ 0.89×) × your SSS growth lever.
• New stores — each applies the median ramp curve observed across recent TDB openings, not a guess.
• Closures — remove run-rate from the month they leave; you set how many.
• Liquivida — adjustable monthly overlay (default $500K), applied to forecast months only so the validated history stays untouched.
