* fix(fig): keep variable metadata, plugin data and default mode on save
Saving a .fig rebuilt every variable record from the model, which held none
of Figma's variable metadata, so each save wrote variables as published to
all scopes with no description or code names, dropped other plugins' data,
and made the first mode the default.
Variables now carry scopes, codeSyntax and pluginData, collections carry
pluginData, and the reader and writer translate description,
symbolDescription, isPublishable, variableScopes and codeSyntax. Figma has
no default-mode field, so setting a default moves that mode first (undo
restores the order) and the writer orders the default first.
This is the base for design tokens: the CSS name will live in
codeSyntax.WEB and unit and mode conditions in OpenPencil plugin data.
* refactor(scene-graph): share the default-first mode order
setDefaultMode and the .fig writer both moved the default mode first by
hand; modesDefaultFirst does it once, with es-toolkit's partition.
* fix(core): undo a default mode change on the collection currently in the graph
Undoing a collection's removal restores a copy of it, so the inverse of
setDefaultMode wrote the previous order and default to an object the
graph no longer held when both were undone. Look the collection up by id
when undoing, as the forward step already does.
* test(core): move the fig round-trip suite into the package test home
The reader change added `verifier-contracts.test.ts` under
`tests/engine` and grew the migration baseline to admit it, which the
testing architecture forbids: new tests go to the canonical home and
the baseline only shrinks. It also started
`packages/core/tests/io/formats/fig/roundtrip/`, leaving two homes for
one domain.
These tests drive Core's exporter, so Core's home is the canonical one.
The directory moves whole — eleven files, its helpers and raw verifiers
with it — and picks up the local `assert`, `traversal`, `test-utils`
and fixture helpers already there. The baseline loses nine entries.
* refactor(core): address test helpers by alias instead of drilling
`open-pencil/no-deep-parent-relative-imports` already forbids `../../`
drilling, but `lint:structure` names the directories it checks and
`packages/{core,scene-graph,vue}/tests` were never added — so the 72
drilled imports in Core's tests, including the ones the round-trip move
just wrote, were never seen.
Core gains `#core-tests/*` beside fig's `#fig-tests/*`, registered with
the architecture rules, and its tests reach their helpers through it
and their source through `#core/*`. The three test directories join
`lint:structure`, which also surfaced six errors they had never been
checked for: four duplicated imports, an empty `noop`, and a
self-assignment the test meant, now written through a named binding.
Both guides state the rule, since a lint nobody can find in prose is
how this went unnoticed.
* fix(tools): point the heavy unit patterns at the relocated round-trip tests
`HEAVY_UNIT_TEST_PATTERNS` still listed the three heavy round-trip
tests under `tests/engine`. `test:unit` discovers them by directory so
the move looked clean, but `--heavy-only` selects by path and silently
stopped choosing them: 8 files, 52 tests, where it now runs 11 and 80.
The 54 editor engine tests move to packages/core/tests/editor with their helpers, importing Core's public subpaths or source modules relatively. The package gains test and typecheck scripts; the first type check fixed nullable lookups, stale imports, and renderer doubles, and graph events now declare the GraphEventRenderer surface they invalidate. The engine baseline drops to 534 files.
