- Add BacktestKraiken.sol: extends MockToken with Kraiken-compatible interface (dual mint overloads — public mint(address,uint256) for EventReplayer and restricted mint(uint256) for LiquidityManager; peripheryContracts() stubs staking pool as address(0)) - Add KrAIkenDeployer.sol: library deploying OptimizerV3Push3 + LiquidityManager on the shadow pool, wiring BacktestKraiken permissions, setting fee destination, and funding LM with configurable initial mock-WETH capital (default 10 ETH) - Add StrategyExecutor.sol: time-based recenter trigger (configurable block interval, default 100 blocks); logs block, pre/post positions (Floor/Anchor/ Discovery tick ranges + liquidity), fees collected, and revert reason on skip; negligible-impact assumption documented as TODO(#319) - Modify EventReplayer.sol: add overloaded replay() accepting an optional StrategyExecutor hook; maybeRecenter() called after each block advancement without halting replay on failure - Modify BacktestRunner.s.sol: replace tokenA/B with MockWETH + BacktestKraiken, integrate KrAIkenDeployer + StrategyExecutor into broadcast block; configurable via RECENTER_INTERVAL and INITIAL_CAPITAL_WETH env vars; executor.logSummary() printed after replay Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

|
|
*
|
|
* Dual mint interface:
|
|
* - MockToken.mint(address to, uint256 amount) — public, inherited from MockToken.
|
|
* Used by EventReplayer to seed historical pool positions without access checks.
|
|
* - mint(uint256 amount) — restricted to liquidityManager.
|
|
* Mirrors Kraiken.mint(uint256) so LiquidityManager operates unchanged.
|
|
*
|
|
* burn(uint256), setPreviousTotalSupply(), outstandingSupply(), and peripheryContracts()
|
|
* mirror the real Kraiken interface that LiquidityManager depends on.
|
|
*
|
|
* Omissions vs real Kraiken (acceptable for backtesting):
|
|
* - No staking pool proportional minting (no Stake.sol deployed).
|
|
* - No ERC20Permit extension.
|
|
* - setLiquidityManager() has no deployer-only guard (script context only).
