All 211 tests pass. ## Summary of changes ### `onchain/src/Optimizer.sol` - **Replaced raw slot inputs** with normalized indicators in `getLiquidityParams()`: - Slot 2 `pricePosition`: where current price sits within VWAP ± 11 000 ticks (0 = lower bound, 0.5e18 = at VWAP, 1e18 = upper bound) - Slot 3 `volatility`: `|shortTwap − longTwap| / 1000 ticks`, capped at 1e18 - Slot 4 `momentum`: 0 = falling, 0.5e18 = flat, 1e18 = rising (5-min vs 30-min TWAP delta) - Slot 5 `timeSinceRecenter`: `elapsed / 86400s`, capped at 1e18 - Slot 6 `utilizationRate`: 1e18 if current tick is within anchor position range, else 0 - **Extended `setDataSources()`** to accept `liquidityManager` + `token0isWeth` (needed for correct tick direction in momentum/utilizationRate) - **Added `_vwapToTick()`** helper: converts `vwapX96 = price × 2⁹⁶` to tick via `sqrt(vwapX96) << 48`, with TickMath bounds clamping - All slots gracefully default to 0 when data sources are unconfigured or TWAP history is insufficient (try/catch on `pool.observe()`) ### `onchain/src/OptimizerV3Push3.sol` - Updated NatSpec to document the new `[0, 1e18]` slot semantics ### New tests (`onchain/test/`) - `OptimizerNormalizedInputsTest`: 18 tests covering all new slots, token ordering, TWAP fallback, and a bounded fuzz test - `mocks/MockPool.sol`: configurable `slot0()` + `observe()` with TWAP tick math - `mocks/MockLiquidityManagerPositions.sol`: configurable anchor position bounds Co-authored-by: openhands Reviewed-on: https://codeberg.org/johba/harb/pulls/649 Reviewed-by: review_bot --- onchain/src/Optimizer.sol | 270 ++++++++++++--- onchain/src/OptimizerV3Push3.sol | 35 +- onchain/test/Optimizer.t.sol | 323 ++++++++++++++++++ .../mocks/MockLiquidityManagerPositions.sol | 27 ++ onchain/test/mocks/MockPool.sol | 76 +++++ 5 files changed, 665 insertions(+), 66 deletions(-) create mode 100644 onchain/test/mocks/MockLiquidityManagerPositions.sol create mode 100644 onchain/test/mocks/MockPool.sol diff --git a/onchain/src/Optimizer.sol b/onchain/src/Optimizer.sol index d2c8063..2a8a0ba 100644 --- a/onchain/src/Optimizer.sol +++ b/onchain/src/Optimizer.sol @@ -7,6 +7,8 @@ import {OptimizerInput} from "./IOptimizer.sol";
