## Raw Kiwi metadata coverage
OpenPencil deliberately preserves many Figma/Kiwi fields even when they are not rendered or editable. These live under `SceneNode.source.fig` and are applied late during `.fig` export. A schema coverage test compares the current `fig.kiwi` `NodeChange` fields against modeled codec fields, raw-preserved fields, and intentionally schema-only metadata buckets so drift stays visible.
| Field group | Import/export | Render | UI | Fidelity impact |
|---|---:|---:|---:|---|
| `source.fig.rawSize` | ✅ | Indirect | — | Preserves original Figma size for round-trip. Cleared when size is edited. |
| `source.fig.rawTransform` | ✅ | Indirect | — | Preserves exact Figma transform. Cleared when transform is edited. |
| `source.fig.rawNodeFields` | ✅ | Mixed | — | Late-applied to exported NodeChange for round-trip fidelity; raw-field and schema coverage tests guard preservation drift. |
| `source.fig.layout` | ✅ | ✅ | ◐ | Preserves original Figma stack metadata while using normalized layout fields. |
| `source.fig.symbolOverrides` | ✅ | Indirect | — | Important for instance override fidelity. |
| `source.fig.componentPropAssignments` | ✅ | Indirect | ◐ | Used for component property fidelity; not raw-editable. |
| `source.fig.derivedSymbolData` | ✅ | Indirect | — | Critical for instance-derived geometry/layout/text. |
| `source.fig.derivedSymbolDataLayoutVersion` | ✅ | — | — | Figma bookkeeping. |
| `source.fig.uniformScaleFactor` | ✅ | Indirect | — | Important for scaled instances. |
| Style IDs: fill/stroke/text/effect/grid | ↩ | — | — | Preserves style linkage for Figma, but OpenPencil has no style manager yet. |
| Component property refs/defs/specs | ✅ | Indirect | ◐ | Full Figma component-property authoring is incomplete. |

| Variable and parameter consumption maps | ✅ | ◐ | ◐ | Filtered/preserved for safe round-trip; normalized bindings cover common cases. |
| Page fields: background, page type, guides | ↩ | ◐ | — | Background/page type/guides mostly round-trip. Guides are not rendered/editable. |
| Text internals: `textData`, layout versions, font version, derived data | ✅ | ✅ | — | Important for text fidelity; most internals are not editable. Imported derived text data, leading trim, decoration style, underline decoration paint/offset/thickness, semantic font metadata, and raw OpenType feature toggles are preserved for round-trip when safe; decoration style/thickness/color now render through CanvasKit.
| `fontVariations` | ✅ | ✅ | — | Variable font axes are imported, rendered, and exported for text nodes and style runs. |
| Raw paint/effect/vector/geometry payloads | ✅ | ✅ | ◐ | Converted fields render; raw payloads preserve Figma import/export details, including mask, background paint, layout grid, export setting, and prototype interaction metadata where safe. |
