The VWAP bootstrap cannot be completed in a single Forge script execution. Two hard time-based delays imposed by the contracts make this impossible:
1.**300 s TWAP warm-up** — `recenter()` reads the Uniswap V3 TWAP oracle and reverts with `"price deviated from oracle"` if the pool has fewer than 300 seconds of observation history. A pool created within the same broadcast has zero history.
2.**60 s recenter cooldown** — `recenter()` enforces a per-call cooldown (`lastRecenterTime + 60 s`). The first and second recenters cannot share a single broadcast.
`DeployBase.sol` contains an inline bootstrap attempt that will always fail on a freshly-created pool. Follow this runbook instead.

## Prerequisites
```bash
# Required environment variables — set before starting
export BASE_RPC="https://mainnet.base.org" # or your preferred Base RPC
Run the mainnet deploy script. `DeployBase.sol` wraps the inline `recenter()` call in a try/catch, so if the pool is too fresh for the TWAP oracle the bootstrap is skipped with a warning and the deployment still succeeds. The deploy script then prints instructions directing you to complete the bootstrap manually.
> **Note:** If the script still aborts during simulation (e.g., due to an older version of `DeployBase.sol` without the try/catch), see [Troubleshooting](#troubleshooting) for how to separate the deploy from the bootstrap.
The Uniswap V3 TWAP oracle must accumulate at least 300 seconds of observation history before `recenter()` can succeed. Do not proceed until 300 seconds have elapsed since pool initialization.
```bash
# Poll until 300 s have elapsed since pool creation
The VWAP bootstrap path in `recenter()` only records the price anchor when `ethFee > 0` (i.e., when the anchor position has collected a fee). Execute a small buy of KRAIKEN to generate that fee.
echo "Recenter cooldown elapsed. Proceeding to second recenter."
break
fi
echo "Waiting ${REMAINING}s more for recenter cooldown..."
sleep 5
done
```

## Step 6 — Second recenter (records VWAP anchor)
The second `recenter()` hits the bootstrap path inside `LiquidityManager`: `cumulativeVolume == 0` and `ethFee > 0`, so it records the VWAP price anchor and sets `cumulativeVolume > 0`, permanently closing the bootstrap window.
# LM should hold ETH / WETH for ongoing operations
cast balance $LM_ADDRESS --rpc-url $BASE_RPC
```

## Troubleshooting
### `forge script` aborts before broadcast due to recenter() revert
Foundry simulates the entire `run()` function before broadcasting anything. If the inline bootstrap in `DeployBase.sol` causes the simulation to fail, no transactions are broadcast.
**Workaround:** Comment out the bootstrap block in `DeployBase.sol` locally (lines 101–145, from `// =====================================================================` through `seedSwapper.executeSeedBuy{ value: SEED_SWAP_ETH }(sender);`) before running the deploy script, then restore it afterward. The bootstrap is then performed manually using Steps 3–6 above.
### `recenter()` reverts with "price deviated from oracle"
The pool has insufficient TWAP history. Wait longer and retry. At least one block must have been produced with the pool at its initialized price before the 300 s counter begins.
### `recenter()` reverts with "cooldown"
The 60 s cooldown has not elapsed since the last recenter. Wait and retry.
### Seed buy produces zero KRK
The pool may have no in-range liquidity (first recenter did not place positions successfully). Check positions via `cast call $LM_ADDRESS "positions(1)"` and re-run Step 3 if the anchor position is empty.
### BootstrapVWAPPhase2 fails with "cumulativeVolume is still 0"
The anchor position collected no fees — either the seed buy was too small to generate a fee, or the swap routed through a different pool. Repeat Step 4 with a larger `amountIn` (e.g., `0.01 ether` / `10000000000000000`) and re-run Step 5–6.
