# V2 Economy Balance Tuning Interface

`@v2/economy-balance-tuning-interface` builds the Phase 72.18.1.12 economy
tuning surface for drop rates, economy prices, and economy rewards. It composes
`@v2/remote-config-service` validation and staging preview APIs so operators can
adjust economy values through remote config without a client patch.

Primary API:

- `buildV2EconomyBalanceTuningSurface`
- `buildV2RemoteConfigValidationRulesSurface`
- `buildV2RemoteConfigPreviewStagingSurface`

The generated publish plan keeps `requiresClientPatch: false` and
`publishesRemoteConfigOnly: true` for valid drop-rate, price, and reward tunes.

Targeted verification:

```bash
pnpm --filter @v2/economy-balance-tuning-interface run typecheck
pnpm --filter @v2/economy-balance-tuning-interface run test
python V2/ue/Tools/check-v2-economy-balance-tuning.py
