The fee starts at 2.00% (cold ceiling), decreases by 0.05% per swap toward a resting floor, and drifts back up 0.005% per block of inactivity. Every 100 swaps, the floor permanently drops by 0.025% down to an absolute minimum of 0.25%. No owner or admin controls; all parameters are immutable constants.

Falls back to a flat fee when the oracle is unset or stale. Ethereum beforeInitbeforeSwap 1 2mo TrinityHookCharges a fixed 3% total fee on every swap (1.5% from each side) by minting ERC-6909 claims in beforeSwap and afterSwap. Fees are periodically settled to three immutable destinations: ~1% burns TRI tokens, ~1% sends ETH to a rewards contract, and ~1% adds liquidity via an engine contract. Only operates on native ETH / TRI pools.

After each swap it reads the current pool tick and records directional curvature statistics (last tick, direction, cumulative turn sum, swap count) on-chain via events and storage, without modifying swap execution in any way.
