## Objective
|
|
|
|
Move firmware screens and Hub UI away from `HardwareBridge` and onto explicit platform services.
|
|
|
|
## Background
|
|
|
|
Firmware splash/crash and Hub currently receive `&mut dyn HardwareBridge` and publish Shell UI directly through it. `DEC-0032` requires migration to platform facades.
|
|
|
|
## Scope
|
|
|
|
### Included
|
|
|
|
- Firmware context uses platform services.
|
|
- Splash/crash screens publish via render sink.
|
|
- Hub input/render uses input/render facades.
|
|
|
|
### Excluded
|
|
|
|
- Do not implement worker.
|
|
- Do not change Hub UX or firmware state machine semantics.
|
|
|
|
## Execution Steps
|
|
|
|
### Step 1 - Update firmware context
|
|
|
|
**What:** Replace `PrometeuContext` hardware bridge field with platform services.
|
|
**How:** Expose only the services firmware needs: input, assets, render sink.
|
|
**File(s):** `crates/console/prometeu-firmware/src/firmware/prometeu_context.rs`, `firmware.rs`.
|
|
|
|
### Step 2 - Migrate firmware screens
|
|
|
|
**What:** Splash and crash screens publish through `RenderSubmissionSink`.
|
|
**How:** Build Shell UI packet and submit owned submission.
|
|
**File(s):** `crates/console/prometeu-firmware/src/firmware_step_splash_screen.rs`, `firmware_step_crash_screen.rs`.
|
|
|
|
### Step 3 - Migrate Hub
|
|
|
|
**What:** Hub uses platform input/render services instead of `HardwareBridge`.
|
|
**How:** Replace activation input and render publication dependencies.
|
|
**File(s):** `crates/console/prometeu-system/src/programs/prometeu_hub/prometeu_hub.rs`.
|
|
|
|
## Test Requirements
|
|
|
|
### Unit Tests
|
|
|
|
- Firmware state tests pass.
|
|
- Hub UI tests pass.
|
|
|
|
### Integration Tests
|
|
|
|
- `cargo test -p prometeu-firmware -p prometeu-system`.
|
|
|
|
### Manual Verification
|
|
|
|
- Firmware/Hub no longer call `publish_render_submission` on `HardwareBridge`.
|
|
|
|
## Acceptance Criteria
|
|
|
|
- [ ] Firmware context no longer exposes the monolithic bridge.
|
|
- [ ] Splash/crash/Hub render via render sink.
|
|
- [ ] Hub input uses platform/input facade.
|
|
|
|
## Dependencies
|
|
|
|
- `PLN-0103`.
|
|
- `PLN-0104`.
|
|
|
|
## Risks
|
|
|
|
- Firmware code is lifecycle-sensitive. Keep behavior changes out of scope.
