# Project Executive Intent: SMI Firmware

Status: active
Type: decision
Role: project-executive-intent-v1

## North Star

Deliver dependable SMI oven firmware that keeps control, monitoring, and alarms operating through storage faults, and releases only behavior proven on both controller assemblies.

## Current Completion Horizon

Complete the SMI 00-05-01 and revised DisplayTest transition through an evidence-backed release decision. "Done" requires the approved return path, the personality update floor, explicit HPT2 card preparation, and forward, return, and refusal tests on both assemblies. A passing build alone does not close this horizon.

## Strategic Context

SMI 00-05-00 introduced HPT2 logging, but lacks the proposed downgrade guard. Production DisplayTest hands off FAT32 media, while SMI prepares HPT2 media explicitly. Firmware candidate identity and exact-byte release controls are established; the full HPT2 claim and SD-card family qualification have separate evidence gates.

## Current Priorities

- Plan the SMI and DisplayTest work under IDEA-0007, using IDEA-0006 for the technical contract.
- Establish the exact revised DisplayTest image and complete software verification while bench transition testing remains paused.
- When the owner resumes bench work, prove the transition on both assemblies and make the release decision from the exact candidate evidence.

## Deliberate Non-Goals

- No automatic SD-card conversion or erase, and no powered SD-card swap.
- No claim that the update Title authenticates its publisher.
- No automatic CVO/DVO release, SD-family approval, ECO, or customer rollout from the SMI transition result.

## Decisions Needed

- Name the revised DisplayTest release approved for return.
- Select the released IMX specimens for refusal tests.
- Decide when to resume bench transition testing.
- A later release decision must identify the exact qualified candidate.

## Review Triggers

- The revised DisplayTest image is selected.
- Bench testing resumes.
- Either assembly produces contradictory transition evidence.
- An exact candidate reaches release qualification.
- The SD qualification or supply-change scope changes.
