# Visual Engineering

Use this profile for reference-driven frontend implementation and visual regression work with real image evidence.

```text
Sol visual lead (active multimodal root)
├── Terra visual analyst (native, image-capable, read-only)
└── Sol visual verifier (MCP, image-capable, read-only)
```

Reference analysis creates textual acceptance criteria before implementation starts. The root then renders the actual UI and supplies both reference and render to the verifier. MCP mechanically validates attachment containment, model/transport modality support, contracts, goal/turn lifecycle, and scope leasing. Stage ordering and production of a meaningful render are instruction- and evaluation-driven.

Cost and latency are high because visual analysis, implementation, rendering, and comparison have real dependencies. Missing images block visual assurance; transport success alone is not a pass.

The visual verifier is a persistent supervised app-server worker controlled by the root, with detach-safe trace, partial evidence, continuation, finalization, and cancellation. The Terra visual analyst remains a Codex-native image participant, so MMO does not claim app-server timing or control enforcement for it; its read-only boundary and output remain advisory and root-verified.
