… on testnet - Restore vETH_Core collateral factor and unpause mint after EBrake tightened the market during DeviationSentinel testing - Clear EBrake snapshot for vETH_Core via resetMarketState - Grant keeper permissions for _setActionsPaused, setCollateralFactor, and resetMarketState on testnet to enable repeatable E2E testing - Update EBrake ABI with new initialize, marketStates, getMarketCFSnapshot, resetMarketState, and MarketStateReset entries - Add ERC20, ResilientOracle, and Comptroller ABIs for simulation

- adds minimal 3-action VIP: restore CF/LT, unpause MINT, clear EBrake snapshot - no permission grants needed — established by bsctestnet.ts (Guardian/EBrake perms) and addendum 1 (Normal Timelock → resetMarketState) - simulation forks from block 100233050 (post-addendum-1, second incident active via Tenderly web action) - serves as reference for minimal governance footprint to recover any future EBrake-tightened market

Summary
Adds two follow-up addendums to VIP-661 to recover the
vETH_Coremarket on BSC Testnet after EBrake tightened it during DeviationSentinel testing, and to establish the operational pattern for future incidents.Addendum 1 — Full Recovery + Permission Setup
One-time VIP that both restores the market and grants Guardian/keeper convenience permissions so future testing iterations don't require a governance VIP.
Actions:

After Addendum 1 was executed, a Tenderly web action re-triggered the DeviationSentinel and EBrake tightened
vETH_Corea second time. Since all permissions were already in place from Addendum 1 (and frombsctestnet.tsfor the original Guardian/EBrake grants), Addendum 2 contains only the three actions strictly necessary to restore a market.This serves as a reference for the minimal governance footprint required to recover any future EBrake-tightened market.
