Merge Risk: 🟡 Moderate · up to Some pools can retain outdated fee settings after a partial RPC failure, and a future fee-module upgrade can produce incorrect quotes. These fee-calculation paths should be corrected before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winDo not move a newer pool state backward.
If pool A is cached at block 200 and pool B is cached at block 100, an update to block 150 fetches from block 101 and skips pool A logs through block 150. This assignment then changes pool A's marker from 200 to 150. The next update replays blocks 151-200 against pool A even though its state already includes them.
Only advance a pool when its current
blockNumberis lower than the successfully processed block.🤖 Prompt for AI Agents

In `@packages/sushi/src/router/rain/VelodromeSlipstreamBase.ts`:
- Around line 700-706: Update the fee-configuration loop in the moduleOk/configs
branch to track whether any pool lacks a config, while continuing to apply valid
configurations. After processing all pools, set shouldResetFees back to true
when a configuration is missing so the incomplete update is retried.
- Around line 324-349: Update initFeeModule so that when secondsAgo identifies a
DynamicSwapFeeModule, it logs the incompatibility and returns false instead of
continuing with successful initialization. Ensure SwapFeeModuleChanged handling
also marks the provider unavailable for this incompatible module, preventing
cached pools from serving incorrect fees and allowing initialization to retry.
In `@packages/sushi/src/router/rain/VelodromeSlipstreamDynamicFeeBase.ts`:
- Around line 276-295: Update otherFactoryEventCases, especially
DefaultFeeCapSet and DefaultScalingFactorSet handling, to respect each pool’s
cached block when applying module-wide defaults. Skip or otherwise prevent an
older module event from mutating a pool whose cached fee state is newer,
including volatility classification changes, while preserving newer pools’
cached defaults during partial updates.
