Below md, the Media DataTable renders as MobileCardRow cards: title as
primary, plus size/HDR/library/year (3-5 fields, null-safe). Card tap
navigates to /files?path=... (same handleRowClick as desktop). The TanStack
column-visibility toggle is absent below md (the card picks the fields).
Pagination is preserved via a standalone MediaMobilePagination component
that mirrors DataTablePagination semantics (rows count, page-size select,
page indicator, prev/next with correct disabled states) off the raw
PaginationState. The duplication is flagged tech debt -- extracting a shared
TablePagination is a follow-up, out of scope for this slice.
Desktop (md+) is byte-for-byte identical: the isMobile===false branch
renders the same DataTable with the same props. enableRowSelection state is
vestigial (no batch consumer on either path); navigation is the correct
primary mobile interaction.
Tests: 5 new covering mobile cards + hidden column toggle + pagination +
card-tap navigation, and desktop DataTable + column toggle. matchMedia
mocked per-breakpoint. 94 tests pass; lint/build green.

Slice 4b frontend half. Jellyfin-touching pages now select a Jellyfin service
instance instead of a machine.
- api/client.ts: Jellyfin-backed calls (counts/libraries/activity/users, media
status/build/stop/force-stop, queryMedia) send jellyfin_service_id.
- hooks/useDashboard, useUsers, useMedia: selector param renamed to
jellyfinServiceId.
- pages/Media + Applications: list jellyfin service instances and persist
jellyfin_service_id in the URL.
- Dashboard (widgets) and Users (default instance) need no selector change.
- Update Applications + Media tests for the new hook/param.
Files/SSH transport keeps machine_id. Verification: frontend lint 0 errors,
build success, 70 tests; backend ruff clean, 222 tests.
Web UI rework. Completes the DataGrid migration (7a + 7b):
- pages/Media.tsx off @mui/x-data-grid + @mui/material onto DataTable:
15 locked columns (title/series/season/episode/type/year/runtime_min/
size/bitrate/hdr/video/resolution/date_added/library/path);
enablePagination + manualPagination + rowCount from queryResult.total;
page state (pageIndex/pageSize) -> offset/limit into useMediaQuery;
onRowClick -> navigate('/files?path=...') preserved; stable path-derived
getRowId so selection survives server paging; column-visibility toggle.
Hard rule honored: NO sorting, NO resizing (visibility-only).
- Migrate Media shell (Select/Input/Progress/Card/grid/Typography/Tabs).
- Media component tests (column set + row-click nav).
- Harness fix: polyfill ResizeObserver in test/setup.ts — jsdom lacks it
and Radix primitives (Select/ScrollArea/etc.) reference it; was causing
cross-test failures once Media pulled shadcn Select into the pool.
Gate: build + lint + test green (23 files / 64 tests).
Backend:
- FastAPI app with 17 REST endpoints covering dashboard, monitoring,
media index, file browser, and jobs
- Reuses existing clients/domain/services unchanged
- pydantic-settings config, dependency injection, CORS setup
- Auto-generated OpenAPI docs at /docs
Frontend:
- Vite + React + TypeScript SPA
- @tanstack/react-query for data fetching with polling
- ag-grid-react for media table and file browser
- recharts for monitoring charts
- Tailwind CSS styling
- 4 pages: Dashboard, Monitoring, Media, File Browser
- Typed API client matching all backend endpoints
Also:
- docs/MIGRATION_PLAN.md with full architecture plan
- Updated .gitignore for both subprojects
- Streamlit app preserved for now (can coexist)
