## Objective

Migrate non-render domains out of `HardwareBridge` into explicit platform services.

## Background

`DEC-0032` permits render to migrate first but requires the full migration to cover audio, input/touch, assets/storage, clock/pacing, and telemetry where applicable.

## Scope

### Included

- Audio service/facade migration.
- Input/touch service/facade migration.
- Assets/storage service/facade migration.
- Clock/pacing and telemetry surface migration where currently coupled.

### Excluded

- Do not change domain semantics.
- Do not implement async IO unless already supported by existing services.

## Execution Steps

### Step 1 - Migrate audio

**What:** Replace `hw.audio()`/`hw.audio_mut()` production dependencies.
**How:** Route through explicit audio platform service.
**File(s):** `crates/console/prometeu-system/src/services/vm_runtime/dispatch.rs`, firmware/host integration files.

### Step 2 - Migrate input and touch

**What:** Replace `hw.pad()`/`hw.touch()` dependencies.
**How:** Expose input snapshots through platform input service.
**File(s):** `crates/console/prometeu-system`, `crates/console/prometeu-firmware`, host input modules.

### Step 3 - Migrate assets/storage

**What:** Replace `hw.assets()`/`hw.assets_mut()` dependencies.
**How:** Route through asset/storage services while preserving commit and bank visibility semantics.
**File(s):** `crates/console/prometeu-system/src/services/vm_runtime`, `crates/console/prometeu-firmware`.

### Step 4 - Migrate clock/pacing/telemetry coupling

**What:** Move any platform-facing clock or telemetry coupling out of `HardwareBridge`.
**How:** Use explicit runtime/platform services.
**File(s):** `crates/console/prometeu-system/src/services/vm_runtime`, HAL telemetry modules.

## Test Requirements

### Unit Tests

- Audio/input/asset syscall tests pass.

### Integration Tests

- `cargo test -p prometeu-system -p prometeu-firmware -p prometeu-drivers`.

### Manual Verification

- `rg "audio_mut|pad_mut|touch_mut|assets_mut" crates/console` does not show production bridge dependencies.

## Acceptance Criteria

- [ ] Audio migrated to platform service.
- [ ] Input/touch migrated to platform service.
- [ ] Assets/storage migrated to platform service.
- [ ] Clock/pacing/telemetry bridge coupling removed where applicable.

## Dependencies

- `PLN-0104`.
- `PLN-0105`.
- `PLN-0106`.

## Risks

- Asset visibility semantics are high risk. Keep behavior-preserving tests broad.
