+ * @title BootstrapVWAPPhase2
+ * @notice Second phase of the VWAP bootstrap for Base mainnet deployments.
+ *
+ * Run this script >= 60 seconds after DeployBase (or DeployBaseMainnet/DeployBaseSepolia)
+ * finishes. The first recenter() sets lastRecenterTime; the 60-second cooldown must
+ * elapse before this second recenter() can succeed.
+ *
+ * What this does:
+ *   - Calls liquidityManager.recenter() a second time.
+ *   - At this point cumulativeVolume == 0 (bootstrap path) and the seed buy has
+ *     generated ethFee > 0, so recenter() records the VWAP anchor.
+ *   - Asserts cumulativeVolume > 0 to confirm bootstrap success.
+ *
+ * Usage:
+ *   export LM_ADDRESS=<deployed LiquidityManager address>
+ *   forge script script/BootstrapVWAPPhase2.s.sol --tc BootstrapVWAPPhase2 \
+ *     --fork-url $BASE_RPC --broadcast
