+| AaveStrategy (real Aave V3 USDT) | [`0x1f34e7b58A81a84Def4fdE0ED23daE4B60c500cf`](https://www.oklink.com/xlayer/address/0x1f34e7b58A81a84Def4fdE0ED23daE4B60c500cf) | 2,429 b |
+
+The hook address ends in `0x...8580` — the low 14 bits encode the permission flags `0x580` (afterAddLiquidity + afterRemoveLiquidity + beforeSwap). Verified via `Hooks.validateHookPermissions` in the canonical `BaseHook` constructor.
+
+Total mainnet deploy cost: **0.000372 OKB (~$0.09)** at 0.02 gwei.
+
+The vault attaches to the canonical Uniswap v4 PoolManager (`0x360E68fa…b9FB32`) and routes idle USDT through Aave V3 (`0xE3F3Caef…84F116`). The IdleStrategy is the active baseline; the AaveStrategy starts as shadow and earns its way to active via the on-chain `consecutiveWins` counter.

+Total deploy cost: **0.000372 OKB (~$0.09)**. The mainnet build uses real USDT routed through real Aave V3, attaches to the canonical Uniswap v4 PoolManager (no PoolManager redeploy needed). The AI operating mode is bounded to `register_strategy / retire / scoring_change / no_action` on chain 196 — new Solidity to mainnet requires human review per `chain_actions_allowed`.
