Stores were only reachable by deep-importing $entities/Font/model, so
consumers reached past the slice public API (FSD anti-pattern D, B-3/D-2).
- convert the Font barrels (root, model, model/store, model/types) to
explicit named exports with export/export type split (B-1)
- re-export the lazy store accessors/classes from the root barrel so the
entity public API is complete and inert at import (construction stays
lazy; the root already loads tanstack via ./ui)
- repoint all consumers (SampleList, SampleListSection, FontList,
comparisonStore, bindings) from $entities/Font/model to $entities/Font
Swap the eagerly-constructed fontCatalogStore singleton for a lazy
getFontCatalog() accessor (plus __resetFontCatalog for tests), so the
InfiniteQueryObserver is created on first use rather than at module load.
Update the model barrels and all consumers (FontVirtualList, SampleList,
SampleListSection) to the accessor.
Also extract createFontLoadRequestConfig from FontVirtualList: it resolves a
font's URL for a weight and returns a 0-or-1 element array, letting callers
flatMap over a list to build load requests and drop unresolvable fonts in one
pass.
FetchFontsByIds was data-access for the Font aggregate wearing a feature
costume: a single FontsByIdsStore (BaseQueryStore over Font's proxy API),
no UI, consumed only by comparisonStore. Move it beside fontCatalogStore
in the Font entity, collapse its deep $entities/Font imports to relative
paths, expose via the Font public API, and delete the feature slice.
Both names were vague or overloaded:
- fontStore / FontStore -> fontCatalogStore / FontCatalogStore
Three font-related stores live in this slice; the new name names the
paginated catalog specifically.
- appliedFontsManager / AppliedFontsManager -> fontLifecycleManager /
FontLifecycleManager
"Applied" collided with the filter-side appliedFilterStore (different
meaning). The class actually orchestrates a load-use-evict lifecycle
with FontBufferCache + FontEvictionPolicy + FontLoadQueue
collaborators, so "Manager" is justified. Companion types file moved
alongside (appliedFonts.ts -> fontLifecycle.ts).
Directories, file basenames, factory (createFontStore ->
createFontCatalogStore), and the AppliedFontsManagerDeps interface all
renamed. All consumers (ComparisonView, SampleList, FontList,
FontApplicator, FontVirtualList, FilterAndSortFonts bindings,
createFontRowSizeResolver, mocks) updated.
The byId font fetch was a verb-oriented capability with a single
consumer driven by a feature need (materializing comparison picks).
That shape belongs at the feature layer, not on the entity.
Move:
- entities/Font/model/store/batchFontStore -> features/FetchFontsByIds/model/store/fontsByIdsStore
- Class BatchFontStore -> FontsByIdsStore
entities/Font retains the transport primitives (fetchFontsByIds,
seedFontCache) and the keyspace (fontKeys); the feature wraps them in
the reactive store. comparisonStore now imports FontsByIdsStore from
the new feature. The proxy API is imported via direct path so vi.spyOn
on the source module still observes the call.
Replace hand-rolled async fetching (fetchFontsByIds + isRestoring flag)
with BatchFontStore backed by TanStack Query. Three reactive effects
handle batch sync, CSS font loading, and default-font fallback.
isLoading now derives from batchStore.isLoading + fontsReady.
