# Mainnet cWUSDC/USDC Repeg Runbook

**Purpose:** Turn the latest read-only preflight into an exact inventory plan for restoring the Mainnet `cWUSDC/USDC` rail toward `1:1`.  
**Scope:** Defended DODO PMM reserve-gap sizing, public Uniswap V2 floor shortfalls, treasury-manager funding needs, and copy-paste operator commands.  
**Safety:** The planner is read-only. It does not broadcast or move funds.

## What this planner answers

- How far the defended PMM is from simple `1:1` reserve parity
- How much USDC is needed to fund one max-sized automated defense cycle
- How far the public pair is below the current policy floor
- Whether the current operator wallet can cover any of those gaps
- Exact commands to fund the manager, top up the defended PMM, and reseed the public pair once inventory exists

## Prereqs

- Run the preflight first:

```bash
bash scripts/verify/snapshot-mainnet-cwusdc-usdc-preflight.sh
```

- `cast` installed
- `python3` installed
- `ETHEREUM_MAINNET_RPC` available
- Optional but useful:
  - `PRIVATE_KEY` or `KEEPER_PRIVATE_KEY` so the planner can inspect the current operator wallet

## Command

Run from the repo root:

```bash
bash scripts/verify/plan-mainnet-cwusdc-usdc-repeg.sh
```

## Artifacts

The wrapper writes:

- `reports/status/mainnet-cwusdc-usdc-repeg-plan-<UTC timestamp>.json`
- `reports/status/mainnet-cwusdc-usdc-repeg-plan-latest.json`

## Key fields to inspect

- `defendedVenue.simpleReserveParity.addQuoteUnits`
- `automation.managerFundingForOneMaxCycle.shortfallUnits`
- `publicLane.policyFloorBaseShortfallUnits`
- `publicLane.policyFloorQuoteShortfallUnits`
- `holderState`
- `holderFundingChecks`
- `blockers`
- `operatorCommands`

## Interpretation notes

- The defended-pool `1:1` number is an inference from matched 6-decimal tokens and equal reserve targets.
- DODO PMM price can still differ from reserve ratio because the PMM curve is not a constant-product pool.
- Re-run the preflight after every liquidity move. Treat the planner as a live calculator, not a one-time document.

## Operator sequence once funding exists

1. Fund the treasury manager with at least one max-sized automated tranche.
Use `operatorCommands.fundManagerUsdc`.

2. Sell the planned USDC amount into the defended PMM.
Use `operatorCommands.tradeDefendedPoolQuoteIn`.

3. Reseed the public pair to at least the current policy floor if public routing / discovery should be healthy again.
Use `operatorCommands.reseedPublicPair`.

4. Re-run both read-only checks.

```bash
bash scripts/verify/snapshot-mainnet-cwusdc-usdc-preflight.sh
bash scripts/verify/plan-mainnet-cwusdc-usdc-repeg.sh
```

5. Only after the defended lane is re-funded should you consider a managed quote-push cycle.

```bash
bash scripts/maintenance/run-mainnet-cwusdc-usdc-support.sh --health-only
```
