Rehype Doppler Hook

When to use

• Tasks mention Rehype, buybacks, fee distribution, or claimAirlockOwnerFees
• You are working in src/dopplerHooks/RehypeDopplerHook.sol
• You are troubleshooting hook-driven swap behavior for pools managed through DopplerHookInitializer

Prerequisites

• Pool asset address
• Access to DopplerHookInitializer.getState(asset)
• Correct signer (buybackDst for fee distribution updates, airlock.owner() for owner-fee claims)

Core workflow

1. Resolve pool context from initializer state and derive poolId.
2. Read hook state:
   • getFeeDistributionInfo(poolId)
   • getHookFees(poolId)
   • getPoolInfo(poolId)
3. Apply operation:
   • Update distribution with setFeeDistribution(...) from buybackDst
   • Collect beneficiary-directed fees with collectFees(asset)
   • Claim 5% owner fees with claimAirlockOwnerFees(asset) from airlock.owner()
4. Validate storage resets and token balance deltas after each action.

Quick facts

Item	Detail
Initializer integration	Uses DopplerHookInitializer.getState(asset)
Distribution authority	buybackDst only
Airlock owner fees	Separate 5% bucket, claimable via claimAirlockOwnerFees
Primary tests	test/integration/RehypeDopplerHook.t.sol

Failure modes

• Distribution does not sum to WAD
• Non-authorized caller for distribution update
• Non-owner caller for owner-fee claim
• Assuming hook fees equal transferable balances without checking internal buckets
