features. Every mutating tool returns a structured truth: what changed, what
warnings the regenerator raised, and hints for the next move. Multi-view PNG
renders come back as image content so Claude can actually see the part.

Includes a vision-decomposition skill that walks Claude through reading an
engineering reference image *before* building. See `RESEARCH.md` for the
benchmark data behind that workflow.

## What you get

- **Truth-telling on every mutation.** Every tool returns `{ok, status,
  feature_id, feature_name, error_message, changes?, hints?}`. Silent regen
  failures are surfaced, warnings are enriched with actionable fixes.
- **Vision.** `render_part_studio_views` and `render_assembly_views` return
