The ramp reacts to trade size relative to pool depth, so the same quote amount pays a higher fee in a shallow pool than in a deep one. The ceiling is a hard bound: the hook rejects a ceiling below the base fee outright.

How it behaves
Dynamic fees: 0.3% base, ramps to 3% on large trades
Stacks with the other native blocks; the builder flags parameter conflicts, like the anti-snipe guard against the Nth-buy pot, before deploy.
What it does
The LP fee scales with how much of the pool's in-range depth a trade consumes, from your base fee up to your ceiling. No oracle involved.
