📝 Walkthrough

Walkthrough

Consolidates dataset/model detail pages into a single purpose-aware FilesetDetailRoute, replaces dataset/model route params/helpers with fileset variants, refactors FilesTab and card/metadata components to use fileset props, and updates navigation and tests to use filesetName/filesetDetail.

Changes

Fileset Detail Route Consolidation

Layer / File(s)	Summary
Route constants and helpers web/packages/studio/src/constants/routes.ts, web/packages/studio/src/routes/FilesetDetailRoute/constants.ts, web/packages/studio/src/routes/utils.ts	ROUTE_PARAMS replaces datasetName with filesetName; new filesetDetail route added to ROUTES; FilesetDetailTab enum (card/files) and type-guard introduced; old getDatasetDetailRoute and getModelDetailRoute helpers removed and replaced with getFilesetDetailRoute.
FilesetDetailRoute implementation web/packages/studio/src/routes/FilesetDetailRoute/index.tsx, web/packages/studio/src/routes/FilesetDetailRoute/index.spec.tsx	Main route component fetches fileset, derives UI text and default tab from fileset.purpose, wires tab selection to ?tab= query param, and renders FilesetCard + FilesTab with fileset-oriented props. Tests verify tab switching, query-param preview behavior, and purpose-dependent card labeling.
FilesetCard component (card tab) web/packages/studio/src/routes/FilesetDetailRoute/FilesetCard/index.tsx, web/packages/studio/src/routes/FilesetDetailRoute/FilesetMetadataPanel/index.tsx, web/packages/studio/src/routes/FilesetDetailRoute/FilesetCard/ReadmeBody.tsx	Renamed from ModelCardTab to FilesetCard; filesetName prop replaces modelName; FilesetMetadataPanel replaces ModelMetadataPanel; error/missing-README messages generalized from model-specific to fileset-wide copy.
FilesTab refactoring web/packages/studio/src/routes/FilesetDetailRoute/FilesTab/index.tsx, web/packages/studio/src/routes/FilesetDetailRoute/DatasetSchemaEditor/index.tsx	Converted to presentational component receiving fileset, files, isFilesError, isFilesFetching from parent instead of self-fetching. Schema editor panel gating now uses fileset.purpose === FilesetPurpose.dataset. File explorer/preview logic retains query-param control; test IDs updated.
Navigation and route integration web/packages/studio/src/components/FilesetCreateModal/index.tsx, web/packages/studio/src/routes/FilesetListRoute/index.tsx, web/packages/studio/src/routes/FilesetNewRoute/index.tsx, web/packages/studio/src/routes/index.tsx	FilesetCreateModal, FilesetListRoute, and FilesetNewRoute now use getFilesetDetailRoute for all post-action navigation instead of dataset/model-specific routes. FilesetDetailRoute lazy-loaded in route index with unified error panel and suspense fallback.
Cleanup and test updates web/packages/studio/src/routes/ModelDetailRoute/FilesTab/index.tsx, web/packages/studio/src/routes/ModelDetailRoute/constants.ts, web/packages/studio/src/routes/FilesetDetailRoute/FilesetMetadataPanel/utils.spec.ts, web/packages/studio/src/tests/title-change.spec.tsx	Deleted ModelDetailRoute/FilesTab and ModelDetailRoute/constants; updated test imports to use fileset route modules; test params switched from datasetName to filesetName.
