## Summary

| Field | Value |
|--------|--------|
| **Module ID** | E9.M3 |
| **Epic** | [Epic 9 — LiveOps / Integrity](../epics/epic_09_liveops_integrity.md) |
| **Stage target** | Production |
| **Status** | Planned (see [dependency register](module_dependency_register.md)) |

## Purpose

Runtime-safe application of signed `BalancePatch` bundles to combat, progression, and economy knobs with `RolloutState` and rollback story.

## Responsibilities

- Version `ConfigVersion` per patch; stage `RolloutState`; integrate with [E9.M2](E9_M2_KpiDashboardsAndAlerting.md), [E5.M1](E5_M1_CombatRulesEngine.md), [E2.M4](E2_M4_ProgressionPacingControls.md), [E3.M5](E3_M5_EconomyBalancePolicy.md).

## Key contracts

| Contract | Role |
|----------|------|
| `BalancePatch` | Signed tunable diff bundle. |
| `ConfigVersion` | Client/server hash visibility. |
| `RolloutState` | Canary, full, rollback. |

## Module dependencies

- **E9.M2** — KpiDashboardsAndAlerting.
- **E5.M1** — CombatRulesEngine.
- **E2.M4** — ProgressionPacingControls.
- **E3.M5** — EconomyBalancePolicy.

## Dependents (by design)

- Operations UI and automated rollback SLOs.
