## What happened

Phoenix Labs proposed increasing the existing Sentora x Spark RLUSD vault adapter's forced-deallocation penalty from zero to one basis point.

## What changed

Permissionless forced deallocation would burn additional shares from onBehalf, retaining equivalent assets for remaining shareholders.

## What did not change

Ordinary withdrawals and allocator/sentinel deallocation are outside the penalty. Roles and the seven-day setter timelock are unchanged; no execution is established.

## Confirmed

- The target vault is 0xFC8C624B6080a0a780583799f2A862DE936F6E22 on Ethereum.
- The target adapter is 0x743C8eb5dE31E41dEF9048DA268EBd036567cd4e.
- The proposed setter value is 1e14 in WAD units.
- The scope plans a September 14–17 poll, followed by submission only if approved.

## Still open

- Poll approval, mined submission and exact timelock maturity.
- Final execution and reconciliation of any conflicting queued payloads.
- Actual proposed-size exit costs and liquidity under stress.

## What it means for an advisor

- Monitor the vault's forced-exit economics separately from ordinary withdrawal costs.
- Verify exact calldata, maturity and cancellation coverage before updating any vault-specific exit assessment.
