### **1. TL;DR**

This proposal introduces updates to the following components:

- **Initia DEX**
  - Modify `calculate_provide_liqudity_return_amount` to support **non-proportinal liquidity provision**.

- **VIP**
  - Automatically calculate and provide proportional counterparty coins during lock staking (enabled by the new non-proportional support in `0x1::dex`).
  - Add `update_operator_info` function to modify `commission_max_rate` and `commission_max_change_rate` via governance.
  - Add `get_module_store` to expose the module store for `weight_vote`.
  - Add `vote_with_amount` to enable voting with precise amounts.
  - Implement initial snapshot on rollup registration to prevent errors when registration occurs near stage end.

### **2. Background**

**1. Enable Custom Amount Liquidity Provision**

The InitiaDEX (at `0x1::dex`) currently only supports proportional or single-asset liquidity provision. With this update, the contract will support custom (non-proportional) liquidity provision, allowing users to add liquidity to a pool using custom amounts rather than following the standard ratio that matches the current pool asset ratio.

**2. VIP Lock Staking Compatibility Fix**

The VIP lock staking mechanism requires liquidity to be provided proportionally. However, the new custom liquidity provision feature in `0x1::dex` would allow users to bypass this requirement by staking non-proportional amounts (e.g., providing only INIT when providing liquidity and staking in the INIT-USDC pool).

To preserve the intention of the original VIP lock staking mechanism, this proposal includes a modification to the VIP contract that enforces proportional liquidity provision during VIP lock staking, regardless of the custom amount liquidity provision feature.

**3. Misc**

Additionally, features such as `update_operator_info` and `get_module_store` requested by rollup teams are included in this update.
