PR 2 of 4 for the runtime service registry change.
- dashboard_widgets gains service_id + widget_kind columns (legacy
addon_id/widget_type kept but unused).
- Source adapters take (service: ServiceRecord | None, widget_kind, config).
SERVICE_ADAPTERS keyed by service_type; BUILTIN_ADAPTERS for backups/static.
- Backups and static stay as service-less built-ins (service_id nullable),
exposed via GET /api/widgets/builtin.
- SSH task adapter resolves the task + instance, runs over SSH, and appends a
service_task_runs history row on success/failure/timeout/error.
- Retire widgets/registry.py; widget metadata now comes from the integrations
registry + widgets/builtin. Remove /api/widgets/types and /api/widgets/sources.
- Stop default widget seeding (fresh install = empty dashboard).
- Rewrite widget tests around the service-bound + built-in model (26 tests).
Backend-only breaking change; frontend is reconciled in Slice 3. Build/lint
stay green; pytest 222 passed.
PR 4 of 4 for configurable dashboard widgets.
- Replace hard-coded Jellyfin/Backups dashboard sections with a loop that
renders enabled widget instances by sort_order.
- Add WidgetInstance renderer and WidgetConfigDialog for adding, editing,
enabling/disabling, deleting, and reordering widgets.
- Add addon pages for grafana, prometheus, and ssh-tasks at /addons/:addonId.
- Register /addons/:addonId route in App.tsx.
- Update docs/REQUIREMENTS.md with the widget system design and API.
Verification:
- backend ruff clean; pytest 200 passed
- frontend npm run lint: 0 errors
- frontend npm run build: success
- frontend npm run test -- src/widgets/registry.test.ts: 3 passed
The 2026-06-16/17 observability update externalised metrics to
Prometheus + node_exporter + Grafana, but the legacy Manage-side
SSH-scraping monitor was never removed. It duplicated the new stack,
ran SSH df on every machine every 300s, and fed nothing (its UI was
deleted in e2ad731). This slice decommissions the duplication.
Removed (backend):
- services/monitoring_poller.py (MonitoringPoller) — entire file
- services/monitoring_actions.py (disk_space, run_machine_operation,
poll_machine_snapshot, build_machine_client) — entire file;
run_machine_operation had only 2 callers (the poller + /disk), both gone
- tests/test_monitoring_actions.py
- endpoints: POST /api/monitoring/poller, GET /machines/{id}/actions,
GET /disk (and the now-dead _resolve_machine helper)
- lifespan wiring (main.py), dependency wrapper (dependencies.py),
poller.start()/kick() from machine save (routers/settings.py)
- SettingsStore: monitoring_machine_actions table CREATE + 2 indexes +
record/list/prune_machine_actions methods; DROP TABLE IF EXISTS on
startup cleans existing DBs (user-approved)
- config knobs: monitoring_poll_interval_seconds,
monitoring_poll_initial_delay_seconds, monitoring_action_retention_days
- test_api.py: TestMonitoring._ensure_machine + test_disk
Kept (fits the new model): /machines, /prometheus-targets, /alerts,
/alertmanager-status, /alertmanager-webhook; the disk_usage JOB template
(manual on-demand, not monitoring); node_exporter_* machine fields
(they point Prometheus at the right host).
Gate: backend pytest 173 passed; ruff clean.
Move the completed, verified, synced change folder to the dated archive:
openspec/changes/web-ui-rework/ -> openspec/changes/archive/2026-06-17-web-ui-rework/
Canonical spec stays in place at openspec/specs/web-ui/spec.md (not moved).
This is the physical archive step deferred (documented-pending-manual) in
archive-report.md ec46e26; user-approved.
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).
