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.
