Danila Poyarkov 12b6662ba3 fix(fig): keep Figma's order keys on instances and untouched siblings (#819 ) * fix(fig): keep Figma's order keys on instances and untouched siblings Materialized instance occurrences were built without the record's parentIndex position, so every imported instance lost its key and was renumbered on save. They now carry it like other imported nodes. Sibling keys anchored greedily on the first imported key, so a layer moved up past its siblings kept its key and pushed every sibling after it onto a new one. Keep the longest increasing run of imported keys instead, so only the moved and inserted layers are re-keyed. * fix(fig): don't anchor sibling keys on one nothing can precede A moved layer in front of the lowest key ('!') left no room below it, so the anchor was dropped and every sibling up to the next anchor re-keyed. Such a key no longer starts the kept run when a sibling precedes it.		2026-10-04 10:16:01 +00:00

@open-pencil/fig

.fig file-format package for OpenPencil.

The package owns the outer .fig archive boundary and is the staged home for Figma-specific SceneGraph conversion policy. Production SceneGraph read/write remains available through @open-pencil/core/io while conversion modules move behind this package's public API.

Current ownership:

Complete .fig archive parsing through parseFigBuffer()
.fig archive assembly through writeFigArchive()
Canvas payload and image resource handling
readFigContainer() / writeFigContainer() helpers for raw fig-kiwi payloads
.fig source and archive result types
NodeChange-to-SceneGraph property conversion, including styles, plugin metadata, text, paint, vector, and font policy, through @open-pencil/fig/node-change
Component-property, symbol-override, derived-symbol-data, and instance synchronization policy through @open-pencil/fig/instance-overrides
Effective raw-metadata precedence and invalidation over SceneGraph's format-neutral edited-field tracking
SceneGraph-to-NodeChange export conversion with an explicit glyph-outline runtime service
Package-local archive, conversion, instance, export, and dist smoke tests

Architecture documentation

Start with the package docs for the source model, instance evaluation, materialization, document sessions, export, and validation contracts.

Planned ownership:

Oracle-backed .fig fixtures

Non-goals:

Generic Kiwi schema/runtime internals — use @open-pencil/kiwi
Format-neutral IO registration, export targeting, CanvasKit thumbnails, or browser workers — use @open-pencil/core/io
Editor actions, renderer behavior, Vue/app UI, CLI formatting, or MCP transport

This follows the existing @open-pencil/pen pattern: a format package owns its source model/parser and SceneGraph policy, while core registers it in the shared IO system.
