Objective

Remove HardwareBridge from the codebase and publish the new platform layer contract in specs.

Background

DEC-0032 explicitly forbids preserving HardwareBridge as final compatibility. After all domains and tests migrate, the bridge must be deleted.

Scope

Included

  • Delete HardwareBridge.
  • Remove exports/imports and adapters that only preserve bridge compatibility.
  • Update canonical specs in English.
  • Run validation and broad tests.

Excluded

  • Do not implement the real render worker.
  • Do not change platform service semantics beyond cleanup.

Execution Steps

Step 1 - Delete bridge

What: Remove HardwareBridge trait and module. How: Delete source file and remove exports/imports. File(s): crates/console/prometeu-hal/src/hardware_bridge.rs, crates/console/prometeu-hal/src/lib.rs, all remaining imports.

Step 2 - Remove compatibility adapters

What: Delete migration-only adapters. How: Replace final references with direct platform services or remove dead code. File(s): HAL, drivers, system, firmware, host modules touched by previous plans.

Step 3 - Update specs

What: Document platform layer and removal of monolithic hardware bridge. How: Update runtime/host/render specs in English. File(s): docs/specs/runtime/*.md and related canonical specs.

Step 4 - Validate and test

What: Run discussion validation and broad test suite. How: Use discussion validate and cargo tests for affected crates. File(s): repository root.

Test Requirements

Unit Tests

  • HAL, drivers, firmware, system tests pass.

Integration Tests

  • Host desktop crate compiles/tests.
  • Stress cartridge still runs through local platform path.

Manual Verification

  • rg "HardwareBridge" returns no production references.
  • rg "Hardware::new\\(" returns no runtime-facing dependency; any remaining use is local implementation detail or removed.

Acceptance Criteria

  • HardwareBridge is deleted.
  • No production/runtime dependencies remain.
  • Specs describe platform services/facades.
  • Tests pass.
  • AGD-0043 can proceed without needing &mut Hardware, &mut Gfx, live FrameComposer, or mutable VM state in the worker.

Dependencies

  • PLN-0107.
  • PLN-0108.

Risks

  • Removing the bridge too early will cause broad breakage. Only execute after dependency searches show all call sites have migrated.
